A client who goes quiet after receiving your invoice is frustrating — but there are clear steps you can take, legal rights you can enforce, and systems you can put in place so it happens less often. This is exactly what to do.
You delivered the work. They accepted it. You sent the invoice. And now — nothing.
No payment. No response. No explanation. Just an outstanding balance sitting on your receivables list while you decide how to handle it without it becoming a bigger problem than it already is.
This situation is more common than most South African business owners admit publicly, and it has a clear playbook. Whether the client is genuinely stuck, quietly hoping you will drop it, or somewhere in between, there are steps you can take that are proportional, professional, and legally grounded.
Here is exactly what to do.
Not all non-paying clients are the same. Before you decide what to do, it helps to diagnose the situation accurately — because the right response to "client is stuck in a cash flow crunch" is different from "client is ignoring the invoice deliberately."
The overworked contact. The person you dealt with received the invoice but has not passed it to accounts payable, or does not have authority to approve it. The invoice is in their inbox. Nobody is being dishonest — the process just got stuck.
The cash flow squeeze. The client is waiting for their own payment before they can release funds to you. They may intend to tell you this but feel embarrassed. A direct, non-judgmental question — "Is there anything holding up the payment I can help with?" — often surfaces this quickly.
The soft dispute. They have a problem with the invoice or the work — scope creep, a deliverable they are unhappy with, a line item they did not expect — but they have not raised it because they are also avoiding the conversation. This is frustrating, but it is better to know about it at day 14 than day 60.
The deliberate delayer. Some clients delay payment as a cash flow management strategy. They know the invoice is due. They are just seeing how long they can hold it. Consistency in your follow-up is the main tool here — they pay the vendors who chase promptly and let the passive ones wait.
The non-payer. A small percentage of clients genuinely do not intend to pay. This usually becomes clear after two or three ignored formal communications, at which point legal options are appropriate.
Knowing which of these you are dealing with shapes everything else.
The longer you wait, the more uncomfortable the conversation becomes — and the easier it is for the client to treat the invoice as an afterthought.
At 5–7 days overdue, send a direct email:
Subject: Invoice #[INV-XXX] overdue — quick follow-up
Hi [Name],
I am following up on Invoice #[INV-XXX] for R[amount], which was due on [date]. Just checking it came through okay and there are no issues on your end.
Happy to resend if needed. Payment details are included.
Kind regards,
[Your name]
Attach the invoice. Keep the tone light. Most late invoices at this stage are genuinely forgotten — this email alone resolves it.
If there is still no payment or response after two weeks, move from nudge to direct request. Ask for a date:
Subject: Invoice #[INV-XXX] — payment date?
Hi [Name],
Following up again on Invoice #[INV-XXX] for R[amount] — now [X] days overdue.
Can you give me an expected payment date? I am not looking to cause difficulty, just need to know where it stands.
If there is an issue with the invoice or anything on the work side you want to raise, I am happy to discuss it.
Regards,
[Your name]
The request for a "payment date" rather than "payment" is deliberate — it is easier to respond to, and it creates a micro-commitment that most clients honour.
By three weeks overdue, you have sent two emails that have not moved anything. Time to change the medium.
A phone call is the most effective next step. It is immediate, personal, and harder to ignore than another email. Keep it factual and brief:
"Hi [Name], this is [your name] from [your company]. I am calling about Invoice [number] for R[amount] — it has been three weeks past due now. I wanted to check if there is something I can help with to get it processed."
A WhatsApp message is appropriate if you have that kind of working relationship with the contact:
Hi [Name] — just following up on Invoice #[INV-XXX] for R[amount]. Three weeks overdue now. Can you let me know what is happening with it?
Document whatever they say. If they give you a date, write it down with a timestamp. If they tell you it is with accounts, get a name.
At 30 days overdue, the situation has moved past the polite reminder stage. You send a letter of demand — by email is legally acceptable in South Africa, with read receipt enabled.
This letter should include:
Letter of Demand — Invoice #[INV-XXX]
Dear [Client name / Company name],
This letter serves as formal notice that Invoice #[INV-XXX] in the amount of R[amount], issued on [issue date] and due for payment on [due date], remains unpaid.
You are hereby required to make payment in full by [specific date — 10 business days from today].
Should payment not be received by this date, we will proceed without further notice to recover the outstanding amount through the Small Claims Court, Magistrate's Court, or registered debt collection services, as appropriate.
This notice is issued without prejudice to any other rights and remedies available to us.
[Your name, company name, contact details, date]
Keep this professional and factual. The goal is not to threaten — it is to make clear that you are serious and that you know your options.
If the letter of demand produces no payment and no credible response, your legal options are:
Small Claims Court — for amounts up to R20 000, this is the most practical starting point. You file at your nearest Magistrate's Court, pay a small fee, and a date is set. No legal representation is required or permitted — the commissioner hears both sides directly. Turnaround is typically 4–8 weeks from filing. A judgment in your favour can be enforced against the client's assets.
Magistrate's Court — for amounts between R20 000 and R400 000. An attorney is recommended and likely necessary. The process takes longer but the judgments are enforceable and can include interest and costs.
High Court — for amounts above R400 000. This requires an attorney and becomes significantly more expensive. Relevant for large commercial disputes.
Registered debt collectors — governed by the Debt Collectors Act 114 of 1998. They work on contingency (a percentage of what is recovered — typically 15–25%). Useful when you want to recover a debt without the time investment of legal proceedings. They can be effective even without formal legal proceedings, particularly for amounts under the Small Claims threshold.
Attorney's letter of demand — even if you do not intend to sue, a letter from an attorney often produces payment when your own letters have not. Many clients pay immediately when they see a law firm letterhead. Costs a few hundred rand and often resolves the matter without proceeding further.
A few things worth knowing as a South African business owner:
Invoices create a legal obligation. Once your client accepted your goods or services and you issued a compliant invoice, they are legally obligated to pay it under the agreed terms. Silence is not a defence.
Interest on overdue amounts. You can charge interest on overdue invoices if your contract or invoice terms specify it. The Prescribed Rate of Interest Act provides a default rate (prime + 1%) where no rate is specified, but it must be mentioned in your terms to be claimable.
The National Credit Act applies where a credit agreement exists. If you offered payment terms (i.e., do the work first, get paid later), this may constitute a credit arrangement. For consumer clients, Section 129 of the NCA requires a formal notice before legal action.
Prescription. In South Africa, a debt prescribes (expires) after three years of no acknowledgement or payment. Do not leave debts unresolved for years — you may lose the legal right to recover them.
Knowing what weakens your case matters as much as knowing your rights:
No written quote or contract. If you did the work without a written agreement, the client can dispute what was agreed. Always send a formal quote before starting work and keep the accepted copy.
No payment terms on the invoice. An invoice that does not specify a due date or payment terms makes it harder to prove the debt was overdue. Every invoice should state the due date and payment terms.
Verbal agreements about delays. If you verbally agreed to extend the payment date or waive interest, it is much harder to claim those amounts later. If you change terms, do it in writing.
Not following up at all. A court or debt collector needs to see evidence that you made reasonable attempts to collect. Your email trail, call logs, and WhatsApp messages become your documentation.
Non-payment is easier to prevent than to fix. The practices that make the biggest difference:
Upfront deposits on large jobs. A 30–50% deposit aligns incentives and substantially reduces the risk of non-payment at completion. Clients who refuse any deposit are worth scrutinising before you start work.
Clear payment terms in writing. State the due date, accepted payment methods, and interest policy on every document. See our guide on payment terms that work for a practical breakdown.
Credit checks for large new clients. For significant new contracts, a basic credit check is a reasonable step. CIPC (Companies and Intellectual Property Commission) provides basic company verification; Experian and TransUnion offer commercial credit checks.
Follow up before the due date. A quick message two or three days before payment is due — "Just a reminder that Invoice #XXX is due Friday" — catches any last-minute issues early enough to resolve them before the invoice goes overdue.
Automate your follow-up. The biggest single change most South African businesses can make is to follow up consistently. Automatic invoice reminders — via email, WhatsApp, or phone — run on schedule regardless of how busy you are. The clients who pay promptly don't mind; the ones who would otherwise delay get a consistent signal that you are watching your receivables.
A client not paying your invoice is not the end of the matter — it is the beginning of a process. That process has clear steps, legal grounding, and predictable outcomes when you follow it consistently.
The two things that determine whether you get paid are:
How early and consistently you follow up. Most overdue invoices resolve at step one or two. The ones that require legal action are the exception, not the rule.
Whether you have a process at all. An ad hoc approach — following up when you remember, dropping it when you get busy — is why most late payment drags on. A scheduled sequence, applied to every invoice, changes the dynamic.
Start the process early. Escalate proportionally. Document everything. And put systems in place so the follow-up happens whether or not you remember to do it.
