Invoice payment terms in South Africa: what to use and how

Invoice payment terms tell your customer when and how an invoice must be paid. Common choices in South Africa are "due on receipt", 7 or 14 days for smaller clients, and 30 days from invoice or "30 days from statement" for corporate customers. The best terms are short enough to protect your cash flow, agreed in writing before work starts, and printed clearly on every invoice.

Here is how each option works, how to choose, and what to include so there is no room for argument later.

Common invoice payment terms

"30 days from invoice" vs "30 days from statement"

These sound similar but are not. An invoice dated 3 June on 30 days from invoice is due on 3 July. On 30 days from statement, the June statement is issued around 30 June, and payment is due about 30 days later, near the end of July. That is almost two months after the work.

Many large South African companies and government entities run their payments on statement cycles and fixed payment runs. If you sell to them, learn their payment run dates and submit invoices before their cut-off, or you can lose a whole month.

How to choose your terms

Ask four questions:

1. What can your cash flow handle? If paying staff and suppliers depends on each invoice, keep terms short or ask for deposits.
2. What does the customer's industry expect? Corporates may insist on their standard terms; consumers usually pay upfront.
3. How big is the risk? New customers, large orders and custom work justify deposits or upfront payment.
4. Can you automate collection? Card tokenisation or debit orders let you bill on the due date without chasing, which makes recurring services much easier.

A useful default for a small South African service business: 50% deposit on projects, balance on completion due in 7 days, and monthly retainers billed in advance and collected automatically.

Early payment discounts

A term such as "2/10 net 30" means the customer may deduct 2% if they pay within 10 days; otherwise the full amount is due in 30 days. It can speed up cash, but it is expensive: giving up 2% to be paid 20 days sooner is a high annualised cost. Use it only if faster cash is worth that to you.

If you offer a discount and you are a VAT vendor, make sure your VAT treatment of the discount is correct. A prompt-payment discount taken after a tax invoice has been issued may need a credit note. Ask your tax practitioner.

Late payment interest

You can charge interest on overdue invoices if your agreed terms say so. Where no rate has been agreed, South African law generally allows interest on overdue debts at the rate prescribed under the Prescribed Rate of Interest Act, which is linked to the Reserve Bank's repo rate and published in the Government Gazette. The rate changes, so check the latest notice.

Practical points:

• Put your interest rate and when it starts in your terms and conditions, and have the customer accept them.
• Some arrangements, particularly with consumers or where you allow payment over time, may fall under the National Credit Act. Take legal advice before charging interest or fees in those cases.
• Apply interest consistently, or not at all. Charging some customers and not others invites disputes.

Most debts also have a time limit: many ordinary debts prescribe after three years under the Prescription Act. Do not let old invoices sit unchased.

What to put on the invoice

Every invoice should state:

• The invoice date and the actual due date, not just "30 days".
• The payment term in words, such as "Payment due within 14 days of invoice date".
• How to pay: a payment link, and your banking details for EFT.
• The reference to use, normally the invoice number.
• Any late payment interest or early payment discount, consistent with your agreed terms.

If you are VAT registered, the invoice must also meet SARS's tax invoice requirements. See VAT invoice requirements in South Africa.

Worked example

A clearly illustrative example: a Durban IT support company bills a client R11,500.00 including VAT on 5 August 2026.

The same invoice can arrive in your bank account anywhere from a few days to almost two months later, purely because of the term you agreed.

Enforcing your terms without damaging relationships

• Agree terms in writing before you start.
• Send invoices immediately, not at month end.
• Remind customers before and on the due date. Our payment reminder email templates give you wording for each stage.
• Track overdue balances by age so you can act early. An aged receivables report shows who owes what and for how long.
• For regular services, move customers to automatic collection.

Frequently asked questions

What are standard payment terms in South Africa?

There is no single legal standard. Small businesses often use 7 or 14 days, business-to-business services commonly use 30 days, and many large companies pay 30 days from statement.

What does 30 days from statement mean?

Payment is due 30 days after the month-end statement that includes the invoice, not 30 days after the invoice date. It can mean waiting close to two months for payment.

Can I charge interest on late payments?

Yes, if your agreed terms provide for it. Where no rate was agreed, the rate under the Prescribed Rate of Interest Act generally applies. Take advice where the National Credit Act may apply.

Should I ask for a deposit?

Deposits are sensible for new customers, custom work and large projects. A deposit of, say, 30% to 50% with the balance due on completion is a reasonable starting point.
