If you’re running a business in South Africa, one of the first questions is: Do I legally have to send invoices? The short answer is yes—in many cases, especially if your business is VAT-registered. But the rules have details, thresholds, and timing you should know well. And when you do issue invoices, using ProInvoice ensures your invoices are compliant, professional, and defensible.
What the Law Says: Tax Invoices & VAT in South Africa
The VAT Act requires registered vendors to issue a tax invoice for taxable supplies. A full tax invoice must be issued within 21 days after the date of supply.
If the supply amount is greater than R5,000, the full invoice must include all the prescribed information (supplier and recipient details, VAT amounts, item description, serial number, etc.). If the amount is R5,000 or less, an abridged invoice is allowed—fewer details are required. For supplies of R50 or less, you don’t need a tax invoice, but you must still provide some proof of transaction like a till slip or docket that shows VAT involved.
Stay organized as you grow. Use ProInvoice to manage billing and client relationships with ease.
When Invoicing Becomes Legally Essential
You absolutely need to issue invoices when:
- You are registered for VAT, and
- You make taxable supplies (goods/services that are subject to VAT), and
- The transaction meets or exceeds certain monetary thresholds (for a full tax invoice etc.).
Failing to issue compliant invoices can lead to:
- Inability to claim input VAT on expenses.
- Penalties or audits from SARS.
- Difficulty proving income or transactions in case of disputes.
What Must a Legal Invoice Include?
To be valid under South African rules, a tax invoice must contain specific elements. A non-exhaustive list includes:
- Wordings like “Tax Invoice”, “VAT Invoice”, or “Invoice” clearly indicated.
- Supplier’s name, address, and VAT registration number.
- Customer’s name and address, and if they are VAT registered, their VAT number too.
- A unique serial invoice number and date of issue.
- A clear description of the goods or services (with quantity where applicable).
- The amount excluding VAT, the VAT amount, and the total.
Electronic Invoices & Legal Validity
E-invoicing is permitted and increasingly encouraged in South Africa. Electronic documents can have the same legal force as paper invoices if they meet accessibility, integrity, and security standards.
This means you can confidently use tools like ProInvoice to issue legally valid e-invoices that are easy to share, track, and archive.
