Completion Accounts & Purchase‑price Adjustments in South Africa (2026): Step‑by‑step Process, Checklist & Dispute Guide

Completion accounts south africa deals use to fix the final price after a transaction closes, settling the gap between an estimated purchase price agreed at signing and the actual financial position of the target on the completion date. In a 2026 market marked by deal volatility, distressed M&A and heightened business‑rescue activity, the completion accounts mechanism has become a frequent battleground for value leakage and post‑closing disputes. This guide sets out a practitioner’s end‑to‑end workflow: how to draft the completion accounts clause, build a defensible timetable, prepare and review the accounts, calculate the true‑up, and resolve disagreement through expert determination, arbitration or the courts.

It is written for in‑house counsel, private equity and corporate deal teams, and transactional lawyers who need a practical, South Africa‑specific reference rather than a high‑level overview.

Overview: what completion accounts are and why they matter

The completion accounts mechanism is one of two dominant pricing structures in South African share and asset sales. Rather than fixing the price irrevocably at signing, the parties agree an estimated consideration and then adjust it once a set of accounts drawn up as at the completion date reveals the target’s true net debt, working capital and, sometimes, net asset position. The resulting difference, the purchase price adjustment, flows as a payment from buyer to seller or seller to buyer.

What are completion accounts?

Completion accounts are typically a profit‑and‑loss account and balance sheet prepared as at the completion (closing) date, drawn up in accordance with accounting principles specified in the sale and purchase agreement (SPA). They are measured against agreed reference figures, typically a target net working capital and an estimated net debt. Common adjustments include:

• Net debt. Cash, bank balances, loans, overdrafts and finance leases are measured on the completion date; actual net debt is compared to the estimate.
• Net working capital. Trade receivables, inventory, prepayments and trade payables are tested against an agreed working‑capital target or peg.
• Specific items. Tax liabilities, provisions, intercompany balances, transaction costs and deferred revenue are often singled out for bespoke treatment.

Because the accounts are prepared after the buyer takes control, the measurement reflects the state of the business at handover rather than a historic snapshot. Accounting treatment is governed by the principles the parties choose, which in South African practice are usually tied to IFRS/IAS standards, supplemented by SAICA technical guidance and any agreed deal‑specific policies.

Why use completion accounts (buyer and seller objectives)

Buyers often favour completion accounts because they pay for the value actually delivered on the day they assume risk; a leaking balance sheet or depleted working capital is corrected through the adjustment. Sellers may accept the mechanism when the business is volatile or when a fixed price would force them to over‑discount for uncertainty. The trade‑off is reduced price certainty and a materially higher post‑closing administrative and dispute burden compared with a locked‑box structure. The 2026 environment, rapid working‑capital swings, carve‑outs with incomplete standalone records, and distressed targets, has encouraged more South African transactions towards completion accounts precisely because historic accounts can be a less stable price anchor.

Eligibility: when to use completion accounts south africa deals require

Completion accounts are not the right tool for every transaction. They add cost and risk, so the mechanism should be reserved for deals where price certainty cannot safely be set at signing.

Deal scenarios

• Private equity buyouts. PE buyers frequently insist on completion accounts to protect against working‑capital manipulation in the run‑up to closing.
• Carve‑outs. Where a division is separated from a group, standalone accounts may be unreliable, making a post‑closing true‑up useful.
• Distressed and business‑rescue transactions. Rapidly deteriorating balance sheets, creditor pressure and the provisions of the Companies Act 71 of 2008 can make fixed pricing risky; completion accounts allow the price to track a moving target.

Contractual prerequisites

Before committing to the mechanism, confirm that the SPA can support agreed accounting principles, a workable delivery timeframe, a clear review window and an enforceable dispute route. Without these, completion accounts can become a source of leakage rather than protection.

Step‑by‑step process for completion accounts south africa transactions

The following eight‑step process runs from SPA negotiation through to final payment. Each step identifies the action, the lead party and practical drafting positions. The timeline table that follows sets out indicative durations; actual periods must be fixed in the SPA.

1. Negotiate the completion mechanism in the SPA. Lead: buyer and seller legal teams, with accountants advising. Define the accounting basis (the hierarchy of specific policies, then consistent past practice, then the applicable accounting standards), the completion date as the measurement point, the line items to be adjusted, and the reference figures (working‑capital peg and estimated net debt). Buyers typically push for a detailed hierarchy that places specific agreed policies above past practice; sellers often prefer “consistent with the last audited accounts” to limit surprises.

2. Agree the timetable and delivery mechanism. Lead: respective counsel; settle at signing. Fix the number of business days for delivery after completion, the buyer’s review window, the negotiation period and the dispute escalation deadlines. A workable clause reads: “The Seller shall prepare and deliver the draft Completion Accounts to the Buyer within 45 Business Days after the Completion Date.” Build in a deeming provision so that failure to object within the review window deems the accounts agreed, buyers often resist this, sellers favour it.

3. Prepare the draft completion accounts. Lead: seller finance team and external accountants (or the buyer, depending on which party the SPA appoints to prepare). The preparing party assembles the accounts and a full working‑paper pack: trial balances, reconciliations, inventory counts and schedules supporting each adjustment. Thin working papers are a common cause of disputes; insist in drafting that the accounts be delivered “together with reasonable supporting working papers.”

4. Deliver the draft accounts. Lead: preparing party via counsel. Delivery should include management representations and the working papers. The SPA should specify the method of delivery and grant the reviewing party and its advisers reasonable access to the books, records and personnel needed to review.

5. Review and queries. Lead: reviewing party’s accountants and legal team. Within the defined review window, the reviewing party must either accept the accounts or deliver a written objection notice itemising each disputed line, the amount and the basis. Materiality and de minimis thresholds filter out trivial items. A typical clause: “The Buyer shall notify the Seller of any items it disputes in writing within 20 Business Days of receipt, specifying the amount and reasons for each disputed item.”

6. Reconciliation and true‑up calculation. Lead: both parties and their experts. Agreed items are settled; the net adjustment is computed. The calculation should capture interest on the adjustment, any tax effect and treatment of transaction costs, as provided in the SPA. Where the actual net debt exceeds the estimate, the buyer typically pays less (or the seller repays); where working capital exceeds the peg, the buyer typically tops up.

7. Resolve disputes if agreement fails. Lead: expert, arbitrator or court. If the parties cannot reconcile, the SPA’s escalation ladder is triggered, usually a meet‑and‑confer, then referral of accounting items to an independent expert, with broader legal disputes going to arbitration (for example under the rules of the Arbitration Foundation of Southern Africa (AFSA)) or the courts.

8. Finalisation, payment and post‑closing filings. Lead: buyer (payment) and seller (acceptance). Once the accounts are agreed or determined, the adjustment payment is made within the contractual period, interest is settled and any post‑closing accounting and SARS tax filings are updated to reflect the final consideration.

Completion accounts south africa timeline (step, who, duration)

Required documents for completion accounts south africa deliverables

Preparing a complete and authenticated document pack is one of the best defences against dispute. The preparing party should deliver the accounts with management sign‑off, and the SPA should specify whether independent auditor or accountant involvement is required. Use the checklist below as a signing‑room reference.

Timeline & deadlines: how to set the timetable

The completion accounts timeline should be drafted with precision; vague phrasing invites argument. Each period should be expressed in business days and tied to a defined trigger event. Recommended template timings for a mid‑market South African deal are:

• Delivery. Preparing party delivers the draft accounts within 30 to 60 days after completion. For complex or carve‑out targets, 60 days is often prudent; for simple businesses, 30 days may be achievable.
• Review. 20 to 30 business days from receipt of the accounts and working papers, with the clock starting only once the full pack is delivered.
• Negotiation period. 14 to 30 days for the parties to reconcile disputed items in good faith before escalation.
• Expert determination window. Commonly 90 to 180 days from appointment for the expert to deliver a binding determination, though this varies with complexity.

Attach interest to late adjustment payments to discourage delay, a defined interest clause running from the determination or completion date is common. Where the target is in business rescue, the completion timetable must be reconciled with the moratorium and creditor processes under Chapter 6 of the Companies Act 71 of 2008, which can affect the enforceability and timing of adjustment payments. Confirm any CIPC filing requirements for closing deliverables that depend on the company register.

Costs, fees and who bears them

Completion accounts carry preparation, review and potential dispute costs. Allocation is a matter of negotiation, but market norms often place preparation on the preparing party and review costs on the reviewing party, with expert and arbitration fees split or borne as the clause directs. The ranges below are broad indicative estimates only and vary widely with deal complexity; clients should obtain firm quotes from their advisers.

Because fee levels move with inflation, firm size and matter complexity, parties should request current, matter‑specific quotes rather than rely on generic figures.

What changes in 2026

Several trends make 2026 a demanding year for completion accounts in South Africa. Deal teams should adjust their drafting and evidence practices accordingly.

Business rescue & distressed M&A implications

Where a target is subject to business rescue proceedings under Chapter 6 of the Companies Act 71 of 2008, the general moratorium and creditor‑priority rules can constrain adjustment payments and complicate the measurement of liabilities as at completion. Counsel should confirm the business rescue practitioner’s position on any post‑closing payment and ensure the completion accounts clause does not inadvertently prejudice secured or preferent creditors.

Tighter working paper packs and auditor sign‑offs

Many practitioners report a shift towards more robust working‑paper requirements and, in higher‑value deals, independent auditor or accountant sign‑off. The likely practical effect is fewer disputes over the adequacy of supporting evidence, but higher preparation costs. Treatment of events after the reporting period under IAS 10, as published by the IFRS Foundation, is a recurring flashpoint; drafting should state expressly whether and how such events feed into the completion measurement.

Enforcement trends: court capacity versus arbitration

With pressure on court rolls, many transaction teams default to arbitration and expert determination for speed and confidentiality. The practical consequence is that well‑drafted arbitration and expert clauses carry significant weight.

Drafting checklist & sample clause language

Strong drafting is where completion accounts disputes are often won or lost. The checklist below sets out the definitions and clauses that an SPA using this mechanism should contain, together with indicative language and negotiation notes. The sample wording is illustrative only and should be tailored by qualified counsel to each transaction.

Key drafting definitions to include

• Accounting Principles. Define the hierarchy: specific agreed policies first, then accounting policies consistent with the last audited accounts, then the applicable IFRS/IAS standards. Buyers push specific policies to the top; sellers often resist.
• Completion Date. The precise measurement point, including the time of day for cash and net‑debt cut‑off.
• Completion Accounts. The documents to be prepared, their form and the required supporting working papers.
• Adjusted Net Working Capital and Net Debt. Exhaustive definitions listing every included and excluded line item to prevent later argument.

Sample SPA clauses (illustrative)

• Delivery. “The Seller shall prepare and deliver to the Buyer the draft Completion Accounts, together with reasonable supporting working papers, within 45 Business Days after the Completion Date.”
• Review and deemed agreement. “If the Buyer does not deliver an objection notice within 20 Business Days of receipt, the draft Completion Accounts shall be final and binding.”
• Dispute escalation. “Any disputed items not resolved within 20 Business Days shall be referred to an independent accounting expert, whose determination shall be final and binding save in the case of manifest error.”
• Interest. “Any adjustment amount shall bear interest at [agreed rate] from the Completion Date to the date of payment.”
• Arbitration. “Any dispute arising under this Agreement, other than accounting items referred to the Expert, shall be finally resolved by arbitration under agreed arbitration rules, seated in [city], South Africa.”

Negotiation notes: buyers commonly seek broad access to records, a longer review window and no deeming provision; sellers often push for short, final windows, deemed agreement on silence, and a cap on the buyer’s ability to re‑open agreed items. Tax gross‑ups and the interaction with SARS obligations should be addressed expressly, not left to implication.

Locked‑box vs completion accounts

The choice between a locked box and completion accounts turns largely on how far the target’s financial position can be relied on at signing. A locked box fixes the price by reference to an agreed set of historic “locked‑box” accounts, with the seller typically indemnifying the buyer for any permitted‑exception leakage between the locked‑box date and completion. Completion accounts instead defer the final price to a post‑closing true‑up. For stable, audited targets, the locked box can offer certainty and lower administrative burden; for volatile, distressed or carve‑out targets, completion accounts offer protection that a fixed price cannot.

Dispute resolution: escalation, experts, arbitration vs court

When the parties cannot agree the accounts, the SPA’s dispute architecture takes over. A well‑designed clause follows an escalation ladder that keeps accounting questions out of court and reserves litigation for genuine legal disputes.

Typical escalation ladder & timelines

The ladder usually runs: a mandatory meet‑and‑confer within a short window; referral of unresolved accounting items to an independent expert; and arbitration or court proceedings for disputes that fall outside the expert’s accounting remit, such as breach of warranty or fraud. Each rung should carry its own deadline to prevent stalling.

Expert determination: scope, bindingness and selection

Expert determination is a common tool in completion accounts disputes. The expert, typically a chartered accountant agreed by the parties or appointed by a nominated institution, resolves accounting questions and issues a determination that is usually final and binding save for manifest error (as defined in the SPA). Define the expert’s scope tightly: they decide accounting items, not legal construction. The evidence that persuades an expert is the working‑paper pack: trial balances, reconciliations, bank statements, inventory reports and management representations.

Arbitration: rules, seat and enforceability

Where a dispute exceeds the expert’s remit, arbitration (for example under AFSA rules) can offer confidentiality, a chosen seat, access to interim relief and awards enforceable under the Arbitration Act and the International Arbitration Act 15 of 2017 where applicable. Given pressure on court capacity, arbitration’s speed advantage can be significant. Specify the seat, the number of arbitrators, the applicable rules and the availability of urgent interim relief in the clause.

Court remedies

The South African courts remain available for urgent relief, summary judgment on undisputed amounts and application proceedings where the matter turns on documents. Judgments on contractual interpretation and post‑closing disputes can be researched through SAFLII and should inform how clauses are drafted. The trade‑off is a public record and, often, longer timelines than arbitration.

Evidence checklist for a completion accounts dispute

• Working papers. The complete reconciliation pack behind every disputed line.
• Bank statements. Cut‑off period evidence of cash and liabilities.
• Management representations. Signed confirmations relied on in preparation.
• Auditor / accountant sign‑off. Where the SPA required independent review.
• Correspondence. The objection notice and the parties’ good‑faith negotiation record.

Common pitfalls & negotiation traps

• Ambiguous accounting basis. Failing to set a clear policy hierarchy invites argument over which standard applies.
• Incomplete working papers. Thin supporting evidence is a leading cause of disputes and weakens the preparing party before an expert.
• Vague timelines. Periods expressed in “days” without specifying business days, or triggers that are not clearly defined.
• No deeming provision. Without a consequence for silence, review windows can drift indefinitely.
• Inconsistent definitions. Net working capital and net debt definitions that overlap or leave gaps can double‑count or omit items.
• Tax gross‑ups ignored. Leaving the tax effect of adjustments unaddressed can create unexpected SARS exposure.
• Unlimited re‑opening. Allowing a party to re‑open agreed items undermines finality.
• Expert scope creep. Failing to confine the expert to accounting questions pulls legal disputes into the wrong forum.
• Post‑reporting‑period event confusion. Not stating how IAS 10 events feed the measurement.
• Business‑rescue blind spots. Ignoring the Companies Act moratorium when the target is distressed.
• No interest clause. Omitting interest removes an incentive for prompt payment.
• Weak access rights. A reviewing party that cannot access records cannot mount a credible review.

Conclusion

Completion accounts south africa deal teams rely on remain one of the most effective tools for protecting value in uncertain transactions, but their benefit depends heavily on disciplined drafting, a defensible evidence pack and a clear dispute route. In the volatile 2026 market, with more distressed targets, business‑rescue complications and pressure on court capacity, the margin for sloppy mechanics has narrowed. Fix the accounting basis, define every line item, set realistic deadlines in business days, require a robust working‑paper pack and build an escalation ladder that routes accounting questions to an expert and legal questions to arbitration or court.

Done well, the completion accounts mechanism can deliver a fair, final price; done poorly, it can become the very source of leakage it was meant to prevent. This guide is general information and not legal advice; obtain specialist advice on any specific transaction.
