Essential Considerations And Tools For A Commercially Competitive Tender Bid

Tenders are put out when large-scale buyers such as State-owned enterprises advertise their needs and invite bids or tenders from a range of suppliers. They constitute an offer in writing for a company to carry out work or to supply goods or services at a certain price. 

If you are bidding for a high-value tender, plan your tender carefully and consider the requirements involved. For example, ask yourself:

  • What is the cost component breakdown as well as the weight for each of those components?
  • What is the base date for escalation stipulated?
  • What is the frequency of escalation in the contract?

Cost component

A cost component breakdown is a listing of items that will be included in delivering the goods or services being tendered for. It can also be described as the “shopping list” of the components that are being bought by a buying company from a supplying company, whether it is goods or services. Supplying companies are, therefore, advised to put a lot of thought into developing the cost component breakdown. 

If we use a hypothetical example of the manufacturing and supply of a pen, the cost components could typically consist of Labour (to produce the pen), Material (which will in this case be plastic, metal and ink), as well as Transport (to deliver the pen to the buying company). Each of those components will have a weighting agreed upon by both parties assigned to it. For example, labour can have a weight of 30%, material 50%, etc. 

The supplying company must provide the buying company with a cost component breakdown, as the buying company does not know exactly what costs would be undertaken to provide the goods or services required by the tender bid. Some tender bid documents have examples of a cost component breakdown included. 

It is very important to ensure that the supplying company reads and understands the document carefully and properly, and not to simply use the example of the cost component breakdown provided, when completing the tender bid.  The reason is that this might include components that have no relation to the supplying company’s cost components whatsoever, and may have an enormous impact on price adjustment calculations in due course.

Base date 

Each tender bid would specify the base date to be used when completing a price adjustment calculation. This date is normally specified as either the date as at the close of a tender bid, or two months prior to the close of a tender, as the relevant indices may not be available in the current month. The base date of a contract can also be referred to as the starting date for escalation, hence it is very important to ensure that a base date is agreed upon by both the supplier and the buyer and that it is clearly specified for escalation purposes. 

Escalation frequency

The frequency of escalation will depend on the type of goods or services that are being tendered for. Suppliers that complete the tender document must understand fully and specify what the frequency of the adjustment of prices in a contract will be, especially in tenders with very volatile components which are included in the cost component breakdown. 

Referring to the earlier example of the manufacture and supply of a pen, the frequency of escalation could be annually.  On the other hand, if the product or service involved in the tender process is the supply of transport for goods, the frequency of the adjustment of prices on the fuel component of the contract will very likely be more regular than the frequency of the balance of the components. You might find that a transport company stipulates the frequency of escalation as annually, whereas the fuel component would need to be escalated more frequently, most likely on a monthly basis.

SEIFSA Price & Index Pages 

The SEIFSA Price and Index Pages (PIPS) is a tool that is commonly used for Contract Price Adjustments (CPA). The aim of the publication is to provide users with an independent source – based on the arm’s-length principle – from which price benchmarking and adjustments can be made fairly and equitably for suppliers or manufacturers and their respective clients. 

SEIFSA’s PIPS tracks the escalation costs or prices of over 240 different variables. This information is condensed into various price escalation indices and published on a monthly basis. SEIFSA’s independence from any financial gain in these contracts places it in a perfect position to mediate between parties in case of disputes, underpinned by well-researched and audited information. SEIFSA PIPS, therefore, provides a tool for parties in a contract to come to a fair and equitable price increase based on agreed principles, as earlier explained. 

SEIFSA is any company’s best insurance against price increases eroding its company’s profitability and sustainability.

Irrespective of whether you are running a small business or a large enterprise, contracts will become an integral part of your operating environment. This is especially true given that you will have some form of a contractual commitment relating to the purchase or supply of goods and services as part of the day-to-day activities in your business.  Therefore, it is very important for you to implement and manage contracts effectively.

A contract ensures that the interests of both parties are legally protected, while also ensuring that the parties to the contract fulfil their obligations as agreed to.

Once a contract has been signed, it may be very difficult – and  even impossible – to get out of without such action having an adverse financial impact on your business. To ensure that the outcome of a contract is fair to both the buyer and supplier, there are a number of aspects pertaining to contracts that one has to be cognisant of and be familiar with. These include the following:

1. It is better to have contractual agreements in writing

While contracts can be verbal or written, it is advisable to have all agreements in writing. Verbal contracts are often difficult to prove and may lead to additional disputes when misunderstandings occur.  Moreover, because verbal contracts are difficult to prove, they may put a strain on the business relationship of the parties to the contract and may also lead to project cost overruns when parties cannot agree to the terms and conditions. These types of disputes can be avoided by ensuring that all the terms and conditions are written and agreed to by both parties. 

2. Understand the essential elements to a contract

a. Capacity

It is important that the parties to a contract understand the terms and conditions set out by the contract, and that consent to the contract must be given out of free will and must not be forced or influenced.

b. Offer and Acceptance

The agreement will be in force when an offer is made by one party, which is subsequently accepted by the other party to the contract.

c. Certainty

Contracts must avoid vague terminology and should have definite terms, especially given that a court will not uphold contracts that are vague.

d. Possible

The contractual obligations must be possible to carry out.

e. Lawful

If a contract is against public policy or unlawful, the contract will not be legally valid.

3. General terms and structure of an agreement

There is no standard format that a contract must adhere to. The contract will generally include various terms and conditions that will form the basis of the contract. If contract conditions are not met, the contract may be terminated. Moreover, there are different aspects and unique characteristics that are relevant to each contract that one has to consider in drawing up the contract.

4. You do not have to sign the agreement if you don’t understand it

It is important to ensure that both parties to the contract understand the terms and conditions as set out, especially given that the contract is legally binding. If you find yourself in a situation where you are not quite sure what the terms and conditions mean, do not sign and hope for the best. Rather, make sure you get someone to assist you before you sign. This is a very important point, especially if your company is new to the tender and contract space and if you are concerned that you will lose out on a contract being awarded if you do not agree to the terms and conditions that were stipulated at the onset. 

5. Contracts and their contents are negotiable

Contracts contain a lot of details, but  it does not mean that everything is set in stone. The terms and conditions of a contract are negotiable (like the period of the escalation or the size of the fixed portion, etc.). If you do not agree to the terms that are being offered, make a counter offer. For example, if the contract stipulates that a fixed portion of 15 percent should be included in the cost breakdown, you are well within your rights to negotiate a smaller fixed portion. 

6. You need to adjust contracts regularly to ensure that margins and profits are maintained and maximised

More often than not, Contract Price Adjustment-linked (CPA-linked) contracts are escalated on an annual basis. That is because companies (both buyers and suppliers to the contract) regularly cite labour constraints and the administration that is linked to CPAs as reasons for doing escalations annually.  Often times, there is a limited number of employees in a company who are responsible for tendering and contract escalations. If an individual oversees a large number of contracts, there may not be sufficient time to complete normal day-to-day work activities and also do more frequent escalations.

Apart from the work involved in a tender process and contract escalations, parties to a contract generally do not have an understanding of the implications of frequent escalations (e.g. monthly) compared to non-frequent escalations (e.g. annually) on contracts. Generally, input costs change monthly, although there are certain inputs that change on an annual basis, such as labour costs. 

We often receive queries where a supplying company states that the price of some of its input cost components has increased significantly in recent months and that the buying company does not want to accept an escalation to recover the costs. The first point of reference is to refer back to the contract and to determine what was stipulated and agreed upon by both parties. If the contract stipulates that all escalations must be done annually, and if the annual escalation is not currently due, the supplying company will not be able to pass such increases on to the buying company. This will invariably impact negatively on the margins of the supplying company.

Let’s make use of an example to expand further:

For the purpose of this example, we assume that you run a construction company and that you have entered into a two-year contract with a buying company for the building of an office park, and that the parties agreed to an annual escalation. The input cost components may include labour, materials comprising reinforcing steel, cement, bricks, roofing, etc., as well as  transport. 

It is important to highlight that the prices of the majority of the input cost components in your company’s cost breakdown (excluding labour) will change (increase or decrease) on a frequent (i.e. monthly) basis.

In the process of building the office park, your company will incur costs on a frequent basis through the purchase of various materials used in the construction process. Moreover, the price of the items purchased might differ from one purchase to the next as a result of changing input costs that the manufacturer passes on to its buyers – in this case, your company. 

While the price of your inputs will change as a result of changes in the price of the inputs of the manufacturer from whom you bought the products, you will not be able to do an escalation and pass the change in the price onto the buying company. This is because you entered into a contract for the building of an office park where escalations are done on an annual basis, and the annual escalation may not be due yet. This will invariably eat into your margins and profits, in the process impacting on the sustainability of your company, especially given that your company will need to have sufficient cash flow available to continue with the project and to absorb various price increases.

Had you entered into a contract where more frequent escalations were agreed upon, the situation would have been different as you would have been able to pass changes in the price of the inputs used in the construction process on to the buyer on a more regular basis, ensuring the sustainability of your company. Therefore, it is crucial to adjust contracts regularly to ensure that margins and profits are maintained and maximised.

Contract Management is a crucial part of a business and can account for significant leakages in finances and can also have a long-term impact.

SEIFSA can help, both with your Contract Price Adjustment and the drafting or reviewing of your contract or Service Level Agreement, through our Economic and Commercial Division and our Industrial Relations and Legal Services Division.

The Benefits of a Contract Price Adjustment - Linked Contract

The most important factor regarding contract price escalation is that the basis on which this is achieved must be fair and equitable to both parties to a contract. The recovery process should be easy to calculate and administer.

Fixed price contract

A contract that does not contain a clause permitting an adjustment to current price changes that have occurred during the execution of the contract is called a fixed price contract. When the interval between the contract’s date of the tender and the date of the completion is so short that the contractor’s or supplier’s costs vary to a negligible extent, a contractor may be expected to enter into a fixed price contract.

As the general rate of inflation increases, a contractor’s or supplier’s costs are likely to change over a relatively short period of time, so when a supplier commits himself to a fixed price contract, he has no certainty that he will maintain his profit margin.

When entering into a fixed price contract for an extended contract period, the supplier should factor in a contingency provision for inflation into the price or quotation.

Suppliers of goods and/or services are becoming increasingly reluctant to incur cost escalation risks. Their customers are also becoming reluctant to incur the cost of a risk premium in contract prices or to be involved in consideration of whether or not suppliers have over-provided for possible future cost increases in their quotation.

Contract price adjustment clauses seek to establish tender prices at the date of the tender based on known cost and to deal with the subsequent cost escalation risk separation.

Contract Price Adjustment-linked contract

An important aspect of recovering escalations in a contract between two parties is the inclusion of an agreement by both parties on all aspects of a contract escalation or CPA.  The basic logic behind a CPA is to adjust the base price (the price at the start of the period under review) with a market-related change to calculate a new price, ensuring a fair outcome to both parties to the contract.

By using SEIFSA’s Price and Index Pages (PIPS) in a CPA, the buyer in the contract can be certain that market-related increases are paid to the suppliers (as determined by the CPA calculation), ensuring the sustainability/improvement of profitability.

If companies do not stipulate in the contract that an escalation be based on SEIFSA’s formula and indices, suppliers to a contract can submit price increases as they please. Similarly, buyers in the contract can reject any claims as they please. Thus, companies/trading partners

[image_with_animation image_url="40340" alignment="" animation="Fade In" border_radius="none" box_shadow="none" max_width="100%" img_link=""]

maximise potential benefits from their contracts by using SEIFSA PIPS in their CPA calculations.

The formula method

The formula method of recovery breaks an item into its various components including fixed costs, labour, material and overhead costs. Each of these components are linked to an index against which escalation is recovered. For example: labour is linked to SEIFSA Table C-3. Table C-3, however, contains four indices ranging from low-skilled labour to skilled labour, and it also contains an index which calculates the average increase in the labour rate across all 13 job gradings as per the Metals and Engineering Industry’s Bargaining Council (MEIBC).

It is, therefore, important to specify the exact index contained in Table C-3 to link to the labour component of a contract i.e. SEIFSA Table C-3: All Hourly-paid employees. The rate of increase of each component is, therefore, directly linked to the increase of the index to which it is linked. The formula method also defines the period over which the escalation will apply for each component.

Advantages of the formula method


The formula method recovers escalation by using indices which are impartial indicators of cost movement. No supporting documentation is required to substantiate the claim , hence full confidentiality is maintained regarding the source and price of goods.

Administrative cost

If a formula and its component definitions have been clearly stipulated and contractually agreed upon, the process of calculating the escalation is fairly simple.

Indirect Costs

These costs are included in the formula and many indices which are compiled from actual costs in the industry include the indirect element of costs.

Profit margins

The original quoted selling price forms the basis on which escalation is calculated. If a formula is applied, the profit margin is maintained.

Control over increases

The formula method only allows increases in relation to the indices defined with it. Since bodies independent of the parties to a CPA agreement supply information which is used to publish indices, neither party can influence or manipulate them. Indices generally reflect the average cost increases within the industry as a whole and not those of any individual supplier.

[image_with_animation image_url="40340" alignment="" animation="Fade In" border_radius="none" box_shadow="none" max_width="100%" img_link=""]

Challenges in using the formula method


In order to keep the formula simple and workable, a formula rarely represents more than 10 components of cost.  As a consequence, it can never be entirely representative of a specific product, group of products or service being escalated. In addition, indices are not always entirely representative of each of the components of the formula.

If indices are not available

It sometimes happens that there is not an index contained in the SEIFSA PIPS which is relevant to a specific product. There is, however, an alternative. SEIFSA refers users of the PIPS to the PPI for final or intermediate manufactured goods. The decision will be based on whether the product is used in the intermediary process or not or, alternatively, which one of the two indices tracks the closest the movement in the cost component.


The need for escalation procedures is clear. In analysing the method of recovery in this section, the conclusion is that the use of a formula is usually the efficient method recovery. The features of the formula method supporting this statement are:

  • A formula gives a clear contractual base by which price increases or decreases can be calculated;
  • Profit Margins are maintained;
  • Minimal time is taken up in the calculation process and administrative costs are low;
  • Confidentiality of price and sources is maintained;
  • Using indices usually caters for indirect costs; and
  • A formula linked to indices is immune to manipulation by either the supplier or the customer.

Although a formula is a mathematical entity, each component is subject to a definition. It is, therefore, vital that each component of the formula agreed upon is clearly defined and is fair to both parties.

It is the mission of SEIFSA’s Economics and Commercial Division to give voice to and raise the profile of the metals and engineering sector in the national discourse on economic, industrial and trade policies. The Economics and Commercial Division also produces its PIPS product and hosts training workshops in which the Division highlights the essence of the indices and the importance of Contract Price Adjustments.

The metals and engineering sector is a strategic industry for South Africa, comprising 45% of manufacturing and contributing 6% to the gross domestic product of the country. Real output in the manufacturing sector accelerated to 4.3% in the third quarter of 2017, following an increase of 1.5% in the second quarter, as activity in manufacturing expanded at a faster pace,  contributing 0.5 percentage points to overall GDP growth. The companies in the sector export 52.1% of their production to the rest of the world, earning valuable foreign currency for South Africa.

The health of the industry is vitally important.

[image_with_animation image_url="17749" alignment="center" animation="Fade In" box_shadow="none" max_width="100%" img_link=""]

The SEIFSA Economics and Commercial Division accomplishes its mission through:

  • Research of economic and cost trends;
  • Communicating sector market intelligence to its members, associates and the general public;
  • Monitoring the international and domestic economic and policy environment;
  • Supporting companies in the sector to make more informed business decisions;
  • Having a particular focus on small and medium size businesses; and
  • Offering a comprehensive advisory service on black economic empowerment and assisting companies to achieve this business imperative.


The Economic and Commercial Division strives to influence the business environment positively by representing the sector in debates and forums about monetary, fiscal, industrial and trade policies.

This is done through:

  • Direct interaction with the relevant institutions in the public sector, like the South African Reserve Bank, the National Treasury, the Department of Trade and Industry, Customs, the National Empowerment Fund and many similar organisations or institutions.
  • It is also done through participation in multilateral forums through Business Unity South Africa and the National Development and Labour Council.

Particular ad hoc research is done from time to time on subjects like the electricity crisis, or the extent and impact of import penetration into the metals and engineering market. In many instances, the very rich knowledge present amongst individuals, or within associations or sub-industries is harnessed and utilised in compiling position papers on issues of importance to the sector.

An example of our market commentary can be seen in our press releases like the one issued  on 28 February 2018, which highlighted the impact of the Producer Price Index (PPI) data released by  StatsSA.

The Stats SA data showed that the PPI for intermediate manufactured goods decreased to 1.5 percent year on year in January 2018, from the 3.2 percent recorded in December 2017.

“This is a poor performance, especially given the four consecutive months of PPI increases for intermediate manufactured goods prior to December 2017,” SEIFSA Economist Marique Kruger said.

Also, given the volatility of input costs in the sector, the deceleration in the PPI data leaves manufacturers with little leeway to pass cost increases on to the market. Correspondingly, SEIFSA’s composite input cost index, which tracks the average cost structure for the M&E sector, was recorded at 1.4 percent in January 2018, up from 3.4 percent in December 2017.

Ms Kruger said it is important to maintain a positive differential in the selling price inflation and input cost inflation in order for the sector to stay attractive for existing and new investments.

“Hopefully, the PPI for intermediate manufactured goods will rebound against the backdrop of a continued improvement in business confidence, especially in light of recent developments in South Africa’s political landscape,” Ms Kruger said.

What is cost price adjustment and why is it so important

Based on the terms and conditions set out in the tender awarded to you, it is now time for you to take stock of what has happened to the price of the product or service you provided over the last couple of months/year. You also need to supply the information to the buying party to your contract. So where to from here?

Unfortunately, you cannot go to the buyer and tell them that your costs have increased by 11% and expect them to pay it, especially if you do not have proof. Without substantial proof to support the increase in the costs you want to pass onto the buyer, your request will not be met. So how do you get the proof? Easy, through calculations in a Cost Price Adjustment (CPA) with the use of relevant industry related price indices which will give you a true and accurate reflection of what has happened in the market.

Alright, so you know you must do a CPA but you have no idea what it is, let alone how to apply it or why it is beneficial to you. The aim of this blog is to do just that – give you a better understanding of what a contract price adjustment is.

[image_with_animation image_url="15054" alignment="" animation="Fade In" hover_animation="none" border_radius="none" box_shadow="none" image_loading="default" max_width="100%" max_width_mobile="default"]

In the simplest terms, a CPA is a process in which you calculate the extent to which the price of inputs of the product or service you supply, has increased or decreased over a specified period of time. This means that due to unforeseen circumstances (i.e. inflation) the cost of doing business has changed and you have to account for it in some way because it ultimately impacts on the price of the contract over the duration thereof.

Both parties to the contract aim to sustain or improve the profitability of their business. Buyers therefore try to manage and maintain their costs, while suppliers want to recover as much cost as possible.

[image_with_animation image_url="14647" alignment="" animation="None" hover_animation="none" border_radius="none" box_shadow="none" image_loading="default" max_width="100%" max_width_mobile="default" img_link=""]

Let me explain the importance of a cost price adjustment with the use of an example:

You are a supplier to a contract. The initial contract value was R10 000 000, the contract term was for 10 years and you were allowed to escalate (do your cost price adjustment) once a year. At the end of the 10-year period the contract value that you calculate by taking costs into account amounted to R14 233 118. One of your colleagues came to you and mentioned that you made an error in your calculations and that the contract value was actually supposed to be R16 894 790. Through discussions with your colleague you actually realise that you applied the calculations incorrectly because you didn’t understand the contract price adjustment process. As a result, your company lost R2 661 671 on the contract. What is worse is that the profit calculated at the start of the contract was R2 000 000 which means that your company actually has to pay in, in order to finalise the project (thereby putting your company in a worse position).

This example can be explained from the buyer’s side as well. Let’s assume the same contract over the same period as in the above example. At the end of the 10-year span the contract cost you R16 894 790. Your colleague then tells you that the cost of the contract was supposed to be R14 233 118. Unfortunately, your company overpaid by R2 661 671 because you didn’t understand the process and applied calculations incorrectly.

As the company supplying the product or service, you are therefore assured that you can justify the cost increase you are passing on to the buyer and that the costs were accurately calculated from your CPA which is based on what has happened in the market. The correct application of the CPA also allows the company buying the product or service to be certain that market related increases are paid out, ensuring the sustainability or improvement of business profitability.

In order to accurately calculate your costs, you need to make use of SEIFSA’s price indices and apply them to the mathematical formula which is based on the inputs of your product or service. Although the mathematical formula is a very important aspect to your CPA, it will be of no benefit if you do not use the correct price indices. The use of the incorrect indices could have an adverse effect on the increase you calculate. Often times the CPA process is handed to staff in financial positions due to the calculations involved. However, it is very important that the technical people in the company assist with the process, especially when tendering. This is because the technical people have a better understanding of what inputs are used in the manufacturing of a product. If for example your company manufactures power transformers, the technical person would know that one of the materials used is electrical steel.

SEIFSA’s Price and Index Pages (PIPS) currently offer a wide variety of steel indices and because you lack the technical knowledge you might link the incorrect steel index to the material component.

If you are worried about changes in the input costs in your tender application or the right time to escalate (that is, make adjustments to your contract), subscribe to SEIFSA’s Price and Index Pages and join a CPA workshop to better understand the process involved.

What are the SEIFSA Indices?

So, you are in the process of tendering for that big contract and it is a requirement that you make use of the SEIFSA indices to assist you in accurately pricing your tender contract. At this point in the tendering process you might not be aware of who SEIFSA is or that SEIFSA even has price indices available. At the same time, you might not have a clear understanding of what an index is, or what the purpose of using an index is, let alone have knowledge of a SEIFSA price index.

The aim of this blog is to give you as a tenderer a basic understanding of indices and to give you an overview of the SEIFSA indices on offer. Lastly, we aim to give you a brief explanation as to why you should use the SEIFSA price indices in the tendering processes and subsequent escalations.

In the most basic sense you use an index as a statistical measure of changes in two or more data points. What I mean here is that one index point (e.g. 102) tells you nothing. In order for indices to have meaning, you need to have at least two index points to calculate the percentage increase or decrease between any two periods. Just by looking at the indices you should already have an indication whether the price of what you are interested in (e.g. domestic merchant steel) increased or decreased between two periods.

[image_with_animation image_url="14647" alignment="" animation="None" hover_animation="none" border_radius="none" box_shadow="none" image_loading="default" max_width="100%" max_width_mobile="default" img_link=""]

Let me show you with an example:


seifsa-indices example


The table above is a hypothetical example giving index points which reflect domestic merchant steel prices for the months of January 2017 and February 2017. Without doing any calculations you can see that there was an increase in domestic merchant steel prices. How? The index value in February 2017 is higher than that of January 2017. Now that you know that the price of domestic merchant steel increased between these two months, you can easily calculate by how much. You can make use of either of the following formulas to calculate the percentage change in the price of domestic merchant steel:

  1. ((New/Old) – 1) *100
  2. (New-Old/Old) *100

Both of the above formulas will give the same results. Based on both formulas and the figures cited in the example, the change in the price will be 2%. There are some advantages to using indices.

Firstly, an index hides sensitive information such as the source of the information or the actual price level and secondly, it minimises errors in computation that are often associated with larger numbers. It is much easier to type 125.1 as opposed to 138 789, which allows for reduced errors. It is also important to understand that a price index only indicates the extent to which the price of an item has changed when compared to some earlier point it time. Moreover, a price index does not give you an indication of the actual level of the variable which means that you won’t know what the exact price of the item (i.e. domestic merchant steel) is. Important to understand is that when the domestic merchant steel price increases by 10% in a given month, that 10% increase will be reflected in the index for that same month.

Now that you have some background on indices, allow me to go into a little bit more detail regarding the SEIFSA indices. Every month SEIFSA updates and publish over 200 price indices in the SEIFSA Price and Index Pages (PIPS). We have time series for some of these price indices dating as far back as the 1960s.

SEIFSA PIPS cover a wide spectrum of price indices which includes but is not limited to labour, transport, overheads and materials. The SEIFSA labour indices cover all 13 job gradings as set out by the Metal and Engineering Industries Bargaining Council (MEIBC). Although our labour indices relate mostly to the Metals and Engineering sector, we also publish labour indices for other industrial sectors.

In addition to indices for petroleum products, we publish two road freight (transport) indices that you will apply based on your primary activity of business. For overheads, SEIFSA PIPS offer you indices for both office and production. We also have indices that you could apply if you have an imported component in your cost breakdown. These include exchange rates and imported unit value indices (UVI).

SEIFSA PIPS offer a wide array of indices relating to materials. In terms of steel, our offering includes but is not limited to domestic merchant and producer price and stainless-steel indices. A number of material indices relevant to different type of engineering activities are also available along with commodity indices.

When you make use of PIPS in your tender submission you can be assured that your tender bid is comprehensive and competitive because you will be able to accurately calculate the changes in inputs that affect the final cost of manufacturing. SEIFSA PIPS is the best tool to use to use for contract price adjustment as well.

How the tender processes in South Africa works

Tender processes in South Africa need careful and accurate preparation to help you land that big tender but it can also be a time-consuming and costly exercise, especially if you do not understand the tender bidding process or adhere to the necessary requirements (i.e. submitting all the tender forms). When an organisation such as a private company or government need to obtain specific goods or skills, they will issue a tender bid, an invitation to tender or a Request for Quotations (RFQ). The reason why a RFQ or tender invitation is advertised is to make the process fair and to promote competition by offering an equal opportunity to as many suppliers as possible to submit their tenders.

You will be able to find information on available private company tender bids through adverts in newspapers and in trade and professional magazines. Networking can also be a great way to get information on available tenders. Major national and provincial tenders are normally advertised in the Government bulletin, newspapers, notice boards at various governmental departments, post offices and police stations. Each tender bid will supply information on the following that is important to take into account:

  1. The RFQ or tender number;
  2. A short description on the requirements and eligibility criteria
  3. Closing date, time and address to deliver your tender submission documents. The responsibility lies with you as the tenderer to ensure that your tender bid is received at the required address in good time; and
  4. The compulsory meetings or and special conditions of the contract.

Failure to comply with points 3 and 4 above could lead to the disqualification of your bid. Even if you are aware of where to look for tenders, you have to make sure that your company is legally compliant which will allow you to take part in the tendering process.

Your business has to be registered, with a commendable banking history and you must have a good relationship with your clients and suppliers. Make sure that your company has an excellent credit record by ensuring that you are registered with the South African Revenue Service (SARS), all bills are paid on time and that you are up to date with company tax and VAT payments. Ensure that all your employees are registered with the Department of Labour in terms of Unemployment Insurance Fund (UIF) and Workmen’s compensation fund etc.

Each national or provincial tender has a number of forms that has to be included in your tender submission. These required forms were formerly referred to as tender forms but are now referred to bid documents. Bid documents for national tenders have the prefix of SBD.

Now that you have a better understanding of the legalities of bidding for a tender, you need to also understand the economic aspects to consider when pricing a tender. You need to remember that the pricing of a tender is different from the way you would normally price a product in your company.

Why? As a bidder, you need to consider all the cost associated with undertaking the project to ensure you calculated an optimum mark-up. Imagine you get allocated the tender only to find out that it is not profitable to undertake the tender.

Often times tender documents will state that you have to make use of SEIFSA’s Price and Index Pages (PIPS) (a data set that contains over 200 indices) with some of these indices dating back to the 1960s. The idea is that you link a relevant index to each of the input cost components in the breakdown of your tender application.

By including data from these indices in your tender application, you will be able to accurately calculate the changes in the costs of labour, steel, transport, just to name a few, and other inputs that affect the final cost of manufacturing in a business through the application of a Contract Price Adjustment (CPA). The results from the CPA calculations allow the tenderer to adjust prices in line with unforeseen cost increases.

Furthermore, by using PIPS during the tender processes in South Africa you can be certain that the cost increases you calculated is a true reflection of what happened in the market, thereby ensuring that you maintain and ultimately improve the profitability of your business.

Here are some useful tips to keep at the back of your mind that could potentially increase your chance of winning the tender:

  • Make sure that you provide all necessary information as set out in the tender application. These include updated tax clearance certificate and shareholding certificates, amongst other requirements.
  • Apply the relevant PIPS indices and always double-check the calculations of the prices in your tender application.
  • Only tender for a contract that fits in with the scope of your business. There is no use in tendering for a tender to build a hospital if your company is in the catering industry.
  • If you are unsure of anything, ask.
  • Sign all relevant pages of your bid document as any unsigned documents may lead to the disqualification of your bid
  • Aim to beat the client’s expectations through non-price solutions and sell them upfront. These can include doing the job in less time than required or using fewer resources.

How to use SEIFSA indices for contract price adjustment (CPA)

Congratulations you have just landed a very big tender contract! Despite this significant achievement you are unsure on how to proceed with the process, and different questions come to mind:

  1. What type of price indices does SEIFSA offer?
  2. How do you apply these price indices in your Contract Price Adjustment (CPA); and
  3. What are the benefits of using the SEIFSA price indices in a CPA calculation?

All of the questions are normal to ask, especially to a new user of the SEIFSA Price and Index Pages (PIPS).


The aim of this blog is to assist you as a potential first-time user of SEIFSA PIPS in understanding the price indices and how to apply the same in your CPA after landing that big tender. We also want you to better understand some of the advantages that the correct use and application of the price indices in a CPA can have on the profitability of your business.

Before we go into all the detail, let’s discuss the spirit of the CPA. For buyers the profitability is expressed as a function of how well they are able to manage and maintain their costs, whilst suppliers aim to contain or recover as much of the cost as possible. Both parties aim to sustain or ultimately improve the profitability of their businesses.

For the company supplying the product or service, you are assured that you can justify the cost increases calculated from your CPA based on what has happened in the market. On the reverse side, the company buying the product or service can be certain that market related increases are paid out as determined by the Contract Price Adjustment calculation, ensuring the sustainability or improvement of business profitability.

SEIFSA offers over 200 PIPS indices that relate to the Metals and Engineering sector. We have data for some of these price indices dating back to the 1960s. SEIFSA’s PIPS have been accepted by sales and marketing personnel and contract and procurement managers. Most state-owned entities and mines only allow the use of the SEIFSA Price and Index Pages for calculating CPA on their contracts. The variables include but are not limited to: Labour, transport, steel, stainless steel and metal indices, production consumables and office overheads.

By including data from these indices in your CPA formula to calculate your escalation, you will be able to accurately calculate the changes in the costs of labour, steel, transport and other inputs that affect the final cost of manufacturing in a business. The results from the Contract Price Adjustment calculations allow the tenderer to adjust prices in line with unforeseen cost increases.

Applying SEIFSA PIPS to a contract price adjustment ( CPA )

Now that you have an understanding of SEIFSA’s price indices, the next step is on application in a CPA contract. In your CPA the price is adjusted based on the following contract price adjustment example:

  • P – Escalated or New price
  • P0 – Base price
  • L – Labour percentage
  • S – Steel percentage
  • EI – Relevant index at the end of the escalation period
  • SI – Relevant index at the start of the escalation period

NB! This is a basic example of a contract price adjustment contract based on merits in labour and steel indices only.

Although the mathematical SEIFSA formula is an important aspect in CPA, it is also vital to understand the optimal combination of indices to link to each of your cost components. This can be explained with the following example:

You are an employee in a financial position in a company with the responsibility of negotiating and/or calculating the contract price adjustment.

One of the material components in your contracts is only specified as steel. However, you do not have the technical knowledge regarding the different types of steel and as a result, you might link the steel material component to one of the stainless-steel indices. The hot rolled steel index that you were supposed to use might increase by 20%, whereas the movement in the stainless-steel index that you incorrectly allocated was only 2%, hence drastically impacting your business profit margin.

The basic logic behind a CPA is to adjust the base price with a market related change to get your new price, ensuring a fair outcome for both the supplier and buyer. When you calculate a CPA linked price the risk is spread between both parties to the contract.

It is also very imperative to remember that no 2 contracts are the same. This holds true even if you have 2 or more contracts with the same company to deliver the same product with the same product specifications.  Herewith an example which clearly explain the stated scenario:

You work for company AA that is located in Johannesburg and have 2 contracts with company BB. Based on the terms of these contracts you have to manufacture and deliver the same product with the same specifications but to 2 different branches of company BB. According to the terms of your contracts you have to deliver one of the manufactured products to a BB branch that is also located in Johannesburg while the other product has to be delivered to the BB branch in Cape Town. Thus, due to the geographical distance between your offices in Johannesburg and the BB branch in Cape Town, the transport portion that relates to this contract will be higher than the transport portion of the contract where you have to deliver to BB branch in Johannesburg. Therefore, because no 2 contracts are the same, the CPA formula will be unique per company, contract and product or service. You have to be transparent in calculating your contracts in order not to be accused of transfer pricing.
