When the Contract Starts Cracking - Protecting Your Business Before a Customer Defaults
The first sign that a customer’s cash flow is collapsing is rarely a dramatic announcement from a sombre board. It’s usually an email from accounts payable saying the invoice is “in process”, a phrase with roughly the same evidential value as “the cheque is in the post”. Then comes the request for another statement, another proof of delivery and perhaps another 30 days. These small shifts in routine can be the first indication that the customer is rationing cash.
For South African suppliers, this isn’t merely comic corporate ritual. Business Partners, citing National Treasury data, reported that by the end of the second quarter of 2025, 95 399 government invoices older than 30 days, worth R12,4 billion, remained unpaid. The lesson applies equally to private customers: once formal business rescue, liquidation or litigation arrives, the creditor’s choices narrow, leverage weakens and “stakeholder engagement” becomes the phrase of the hour. Protection starts earlier, while the contract still has teeth and the evidence is still within reach.
Early Warning Signs of Customer Financial Distress
Financial distress usually leaks before it floods. Watch for repeated requests to extend terms, unexplained changes in payment patterns, invoices paid in round amounts rather than matched amounts, shrinking order sizes followed by urgent oversized orders, management departures, returned debit orders, newly disputed invoices, requests to invoice a different entity and sudden enthusiasm for payment plans. One sign on its own may mean very little. Several appearing together deserve attention. A customer that once approved invoices in 3 days but now requires multiple approvals and reconciliations may be rationing cash.
None of these signs proves insolvency, but several appearing together justify a closer look. Credit control should trigger a documented review rather than leaving the sales team to negotiate informal extensions over WhatsApp. Map the exposure - unpaid invoices, committed stock, work in progress, recurring services, retention money and goods already dispatched. Decide who may extend credit, who may compromise a debt and who may authorise continued performance. If those responsibilities aren’t clear, the customer may end up setting the terms by default.
Suspending Performance and Cancelling a Contract for Non-Payment
Start with the contract, not indignation. Check when payment becomes due, whether time is of the essence, what constitutes breach, whether notice must be delivered to a nominated address, how long the debtor has to remedy, and whether suspension or cancellation is permitted. At common law, cancellation generally requires a material breach. An agreement may also contain a lex commissoria: a clause allowing one party to cancel when a specified breach occurs. South African courts take agreed procedures seriously. In Hodgkinson v K2011104122 (Pty) Ltd, discussed by the Association of Arbitrators, a cancellation notice allowing seven days instead of the agreed 14 was defective.
Before sending notice, calculate the amount carefully and separate disputed from undisputed items. Identify each invoice, contractual clause, breach, cure period, delivery method and consequence. An acceleration clause may make future instalments immediately due. A cross-default clause may treat default under one agreement as default under another. Both can be powerful, but only if drafted precisely and invoked consistently. A creditor should select the remedy the contract supports and follow every procedural requirement accurately.
Deposits, Suretyships, Guarantees and Security Before Default
Credit isn’t kindness; it’s unsecured lending with a sales function attached. Before exposure grows, consider a deposit, advance payment, staged billing, retention-of-title wording, a cession of receivables, a bank or on-demand guarantee, or a suretyship from a solvent person or holding company. Match the security to the risk. A deposit reduces exposure immediately, while retention of title may assist where identifiable goods remain recoverable. A guarantee can provide a separate payment route and a suretyship another source of recovery. The important point is that none of these protections looks after itself: its value depends on the wording, the assets behind it and whether it remains enforceable when needed.
Section 6 of the General Law Amendment Act 50 of 1956 requires the terms of a suretyship to be in writing and signed by or for the surety. The parties and principal obligation must be adequately identified. A recurring problem is the director who signs “for the company” but never signs in a separate personal capacity as surety and co-principal debtor. The signature block, capacity and wording must make the personal undertaking clear. Verify authority, marital status (where relevant), asset position, caps, duration, continuing-cover wording, renunciations, and release events. Also distinguish an accessory suretyship from an autonomous demand guarantee, because legal character follows substance rather than the document’s label.
Security also needs maintenance. Obtain current company searches, management accounts and resolutions, monitor expiry dates, and confirm that guarantees haven’t been reduced, released or compromised by later conduct. If an acknowledgement of debt or payment plan is proposed, check the National Credit Act 34 of 2005. In Friend v Sendal 2015 (1) SA 395 (GP), an acknowledgement deferring payment could constitute a credit agreement. Whether the NCA applies will depend on the parties and the transaction, not on the label given to a finance charge.
Late Payment, Waiver, and the Danger of Accidental New Terms
Repeatedly accepting overdue payments can create an evidential mess. A non-variation clause may protect the written bargain from informal amendment, but it doesn’t resolve every question raised by the parties’ later conduct. Waiver is the intentional abandonment of a known right and can, depending on the contract and evidence, be inferred from conduct. In Phoenix Salt Industries v The Lubavitch Foundation of Southern Africa [2024] ZASCA 107, the Supreme Court of Appeal distinguished contractual variation from waiver: one changes the agreement, while the other relinquishes an existing right. The distinction is important when assessing a creditor’s repeated indulgence.
If a creditor allows extra time, record it. State the revised date, whether interest continues, whether security remains intact, that no further indulgence is promised and that rights are reserved. Ensure the arrangement complies with any non-variation and notice clauses. A properly drafted payment plan may stabilise the relationship, but a vague assurance that payment will follow next month merely postpones the decision. Don’t accept part-payment as full settlement by accident, and don’t release security without checking the legal and commercial consequences.
Purchase Orders, Delivery Notes and Evidence That Survives a Dispute
Commercial disputes are won with contemporaneous records, not collective memory. Preserve the signed agreement and amendments, accepted quotations, purchase orders, proof of the customer’s authority, invoices, delivery notes, goods-received notes, timesheets, completion certificates, email approvals, system logs, statements, remittance advices, and reconciliations. Tie every invoice to the order, every delivery to acceptance and every credit to its reason. If the customer disputes quality, quantify the disputed component and obtain the complaint in writing. Records should be organised so that the transaction can be reconstructed without relying on recollection.
Electronic records matter too. Keep the original message, attachment, metadata and audit trail; a cropped screenshot may omit the very context needed to prove what happened. For public-sector customers and municipalities, preserve the procurement chain as well: bid documents, appointment letters, delegated authority, purchase orders and proof that the official who approved the work could lawfully do so. BW Brightwater Way Props v Eastern Cape Development Corporation [2021] ZASCA 47 is a reminder that contracts involving public bodies exist within constitutional and statutory procurement controls. An official’s approval cannot cure an unlawful procurement process.
Act Before Business Rescue Changes the Debt-Recovery Landscape
Timing matters because Chapter 6 of the Companies Act 71 of 2008 changes the landscape once business rescue begins. Section 133 generally imposes a moratorium on legal proceedings and enforcement action against the company unless the practitioner consents or a court grants leave. In Cloete Murray N.O. v FirstRand Bank Ltd [2015] ZASCA 39, the Supreme Court of Appeal described that breathing space as crucial to restructuring. For an unpaid supplier, it means that ordinary recovery steps may require consent or court approval.
This doesn’t mean creditors should engineer preferences, seize assets unlawfully or manufacture evidence before rescue. It means they should lawfully reduce further exposure, perfect existing security where permitted, issue compliant notices and take advice while ordinary contractual routes remain available. Section 136 is not itself a bar on a creditor cancelling a contract. It empowers the business rescue practitioner, during the rescue proceedings and subject to the statutory limits, to suspend wholly, partially or conditionally certain obligations of the company arising under agreements entered into before business rescue. At the first creditors’ meeting, the practitioner explains whether there appears to be a reasonable prospect of rescuing the company, creditors may prove their claims and may determine whether to appoint a creditors’ committee. Creditors should arrive with reconciled claims, supporting documents and clarity about any security they assert.
A Five-Step Customer Distress Protocol for South African Businesses
The legal response will depend on the contract, the type of security held and the customer’s actual position, but the following internal protocol gives businesses a practical starting point before formal insolvency processes begin.
1. Freeze further exposure - pause new discretionary orders and identify work that can lawfully be suspended. Ring-fence customer-owned and supplier-owned property. Escalate exceptions to authorised executives.
2. Reconcile the account - match invoices, credits, payments, delivery records, and disputes. Confirm the balance with the customer without misstating that silence equals agreement.
3. Review the contract and security - test notice periods, breach clauses, acceleration, cross-default, interest, domicilium, dispute resolution, retention of title, guarantees, and suretyships.
4. Preserve evidence - export emails, approvals and system records, identify witnesses, retain originals, and document every concession. Check prescription dates: most ordinary debts have a three-year period under the Prescription Act 68 of 1969, subject to the Act’s rules and exceptions.
5. Send the correct notice - use the agreed address and method, allow the full cure period, and state the intended consequence accurately. Then follow through consistently, documenting any further indulgence or change in position.
The protocol needs named owners, clear thresholds and firm deadlines. Sales, operations, finance and legal must work from the same account history rather than their own versions of events. Decide in advance when future orders move to cash-before-delivery, when security must be topped up and when litigation counsel is briefed. Test the process before a large debtor falters. If the protocol is first read during the crisis meeting, it has arrived too late.
Protect the Contract Before the Customer Defaults
A contract can’t make a customer solvent, but it can help stop that customer’s distress from spreading into your own business. The best protection is a disciplined process that notices deterioration early, limits exposure, records every indulgence and uses security while it still has practical value. That isn’t paranoia. It’s the less glamorous work of recognising that even a long-standing customer can become a serious credit risk.
If a customer’s payment behaviour is changing, it’s worth reviewing the contract and the available security before the problem becomes a formal recovery exercise. NVDB Attorneys can help assess the position, prepare the right notice and work through a commercially sensible response before business rescue, insolvency or litigation limits the available options. Early advice won’t manufacture cash, but it may preserve leverage - and sometimes that’s what keeps a difficult account from becoming a damaging one.
