Pricing Error in a Government Tender? What a Bidder Should Do

Key takeaways

• A bidder that discovers a pricing error after a public tender closes does not have a general right to replace its price. First preserve the exact bid as submitted. Then classify the issue, read the tender's arithmetic-error, clarification, responsiveness and order-of-precedence clauses, and identify what can be established objectively from the closed bid record.
• South African procurement law allows fairness to be assessed in context. In Metro Projects the Supreme Court of Appeal said it may, in given circumstances, be fair to explain an ambiguity, correct an obvious mistake or provide clarification needed for evaluation. The same judgment imposed the controlling limit: whatever is done must preserve fairness, transparency, competitiveness and cost-effectiveness. A later price, omitted cost, new rate, changed assumption or commercially improved offer is not made lawful merely by calling it a clarification.
• Do not send a replacement pricing schedule on your own initiative. A premature correction can obscure the historical bid, create an admission or alter the competitive position. Build a privileged internal reconstruction and get procurement advice before any material external response.
• This guide is current to 21 July 2026. It is for a South African supplier, director, bid lead, finance lead or commercial manager who finds a pricing issue after submission but before a final outcome. It does not determine whether a procuring institution must accept a correction.

Freeze the submitted bid before investigating

Create a read-only evidence set before anyone edits the working files. Preserve:

• the invitation, specifications, bid conditions and pricing schedule;
• every published addendum, clarification and corrigendum;
• the exact uploaded or delivered bid, including native spreadsheets and exported PDFs;
• portal receipts, upload logs, delivery acknowledgements and closing time;
• formulas, cell protection, print ranges and version history that existed at submission;
• supplier quotations, subcontractor inputs and internal approvals used for the price; and
• every communication with the procuring institution after closing.

The National Treasury eTender portal publishes official tender documents and procuring-entity corrigenda. Compare the frozen bid with the final published document set. Work on a forensic copy and record who created it.

Classify the pricing issue precisely

“Pricing mistake” is too broad for a decision. Build an issue register:

Record the submitted value, reconstructed value, supporting cell or page, affected total, evaluation effect and proposed treatment separately.

Read the tender's own correction rule

The invitation and its incorporated conditions are the starting point. Identify:

1. which document governs if the pricing schedule, form of offer, bill of quantities and summary differ;
2. how figures-versus-words, unit-rate, line-total, summation, decimal and omission errors are treated;
3. whether the evaluator may seek clarification and from whom;
4. whether the bidder must accept an evaluator's correction;
5. the consequence of rejecting a proposed correction;
6. whether corrections must be applied consistently across responsive bids; and
7. whether a corrected price must be used for points, ranking, affordability and award.

National Treasury publishes standard SBD pricing forms, but a standard form does not replace the complete tender-specific conditions. Construction, municipal, state-owned-entity and sector tenders may use different standard conditions, data clauses or institutional policies.

As at 21 July 2026, the South African Government page for the Public Procurement Act 28 of 2024 still recorded commencement as “to be proclaimed.” Treasury has explained that commencement may be phased and that the existing framework continues until the relevant provisions and regulations take effect. Verify the institution, tender date, current Gazette, incorporated rules and any transition instrument; do not assume the new Act or one correction clause applies universally.

Separate correction, clarification and amendment

Use this as a triage aid, not a legal conclusion:

Metro Projects does not create a correction right in every deficient bid. In Prosec Guards (2024), the High Court stressed that the duty depends on the circumstances and that a clarification clause did not authorise condonation of material non-compliance. The distinction is between explaining what was already offered and supplying what the bid needed but did not contain.

Build a bid-price reconstruction

Prepare a controlled workbook with four layers:

1. submitted record: every value exactly as it appeared at closing;
2. tender rule: the clause governing that discrepancy;
3. mechanical result: the output of applying the clause without commercial judgment; and
4. commercial consequence: ranking, affordability, margin, scope and performance impact.

For each formula, retain the formula text, inputs, displayed value and source page. Reconcile VAT, provisional sums, discounts, escalation, currency, annual versus total-term pricing and price carried to the form of offer. Have a second reviewer reproduce the result independently.

Do not back-solve an “intended” total and then change rates to make the schedule fit. If the closed record supports two plausible outcomes, record both. Ambiguity is not proof that the preferred price was submitted.

Respond carefully to a clarification request

If the procuring institution writes to the bidder:

• authenticate the sender and preserve the request as received;
• identify the exact clause and authority relied on;
• diarise the response deadline and bid-validity position;
• answer only the question asked;
• reproduce submitted values before explaining any calculation;
• distinguish an evaluator-proposed correction from a bidder-proposed price;
• state whether the response adds any new rate, assumption or qualification;
• reserve rights where necessary without threatening or obstructing the process; and
• obtain the correct internal authority before accepting a changed contract price.

Do not use the response to negotiate, rebalance rates, cure a scope omission, withdraw an unfavourable qualification or reduce a price to preserve first place. Do not describe a replacement spreadsheet as “for clarity” if it contains new commercial inputs.

If the bidder finds the issue without being asked

Do not conceal the problem or improvise an unsolicited amendment. Escalate to the bid owner, finance lead and legal adviser. Check whether the tender provides a notification route.

A controlled notice may identify the tender, submitted page and discrepancy, then ask the institution to apply the published rules. Whether to propose an outcome, accept a calculation or withdraw is fact-specific. Consider bid security, validity, supply capacity and later contractual obligations.

Correction must flow through the evaluation

A permitted correction is not complete when a number changes. The procuring institution must still apply the tender rules and constitutional procurement standard consistently.

In KET Civils (2020), the tender contained detailed rules for discrepancies, unit rates, summation errors, omissions and bidder confirmation. The court criticised an increased adjusted price that was not evaluated with the other bids at that revised amount, as well as a discount opportunity not offered equally. The case does not establish a universal calculation rule; it shows why the actual clause, confirmation record and comparative re-evaluation matter.

In ROMH JV (2025), the High Court upheld a pre-award re-evaluation after a bid evaluation committee corrected its own earlier responsiveness error and assessed the original responsive bids. That was an evaluator correcting its process, not a bidder supplying a new price. Keep those events distinct in the chronology.

Prepare for an adverse outcome without duplicating the remedy process

If the bid is declared non-responsive, disqualified or unsuccessful, preserve the notice, reasons, award information and implementation status. The separate tender-disqualification guide owns the next-stage workflow for reasons, internal remedies, review timing, affected parties and urgent relief. The administrative-review checklist can organise the decision record.

Do not assume that a complaint or reasons request suspends implementation. An administrative action, internal remedy and judicial review have different requirements. Obtain advice early if the contract may be signed or performed.

What to do in the first 24 hours

1. Lock the exact submitted bid and create verified working copies.
2. Download the final invitation, addenda and corrigenda.
3. Classify every affected price, rate, unit, tax and assumption.
4. Map each discrepancy to the exact tender clause and document hierarchy.
5. Reconstruct the submitted and mechanically corrected totals independently.
6. Measure the effect on ranking, affordability, margin and performance.
7. Stop unauthorised contact and replacement-file circulation.
8. Escalate material issues to finance, the bid owner and procurement counsel.
9. Prepare a controlled response plan for any clarification request.
10. Preserve the outcome and implementation record if the issue becomes a dispute.
