Invoicing in South Africa (2026): VAT, SARS Rules & Getting Paid on Time

South African invoicing has two layers: what SARS demands, and what actually gets you paid. Most guides cover the first and ignore the second. Here's both.

Layer 1: What SARS requires

Do you charge VAT at all?

Only if you're a registered VAT vendor. Registration is compulsory once taxable supplies exceed R1 million in any 12-month period, and voluntary above R50,000. Not registered? Then your invoices show no VAT, full stop — charging 15% you can't remit to SARS is a criminal problem, not an admin one.

The full tax invoice (over R5,000)

A valid tax invoice for supplies over R5,000 must contain: the words "Tax Invoice", your name/address/VAT number, the client's name/address/VAT number, a serial number and date, a description of goods or services, quantity or volume, and the price with VAT — either VAT shown separately, or a statement that VAT is included at 15%.

The abridged version (R5,000 and under)

Below R5,000 the client's details can be dropped; below R50, no tax invoice is required at all (a till slip suffices). When in doubt, issue the full version — no one has ever rejected an invoice for containing too much compliance.

Zero-rated and exempt

Exports, certain foodstuffs and fuel are zero-rated (0% VAT but still in the VAT net); financial services and residential rent are exempt. If this paragraph is relevant to your business, one coffee with an accountant will repay itself hundredfold.

Layer 2: Getting paid — the SA reality

Terms that survive contact with SA payment culture

• Due on receipt or Net 7 for new clients. "30 days" in South Africa reliably means 45.
• Deposits for project work — 50% upfront is standard and unremarkable in SA trades and creative work. The invoice for the deposit goes out before work starts.
• EFT details on the invoice itself: bank, account number, branch code, and the reference you want. Every barrier removed is days gained.

The follow-up cadence that works

1. 2 days before due: friendly confirmation — "just making sure INV-2026-014 is loaded for Friday."
2. Day after due: polite but factual — "payment for INV-2026-014 was due yesterday; please confirm the EFT date."
3. Day 7: phone call. In SA, a call still moves money that ten emails won't.
4. Day 14: stop work notice on ongoing projects. Nothing else you can send is as persuasive.

The tooling

All of the above is automatic in Incredibiz: VAT at 15% per line item with the subtotal/VAT/total breakdown SARS expects, sequential numbering, your banking details on every PDF, and the customer record showing what's outstanding. Free plan: 5 invoices a month, R0, no card (top-ups from R29 when you need more) — built in South Africa for exactly this.
