Start with the client and project
Confirm the legal client name, billing contact, service description, agreed currency, and purchase order details before you create the invoice. For South Africa, DingVoice templates default to ZAR so totals stay consistent with the rest of your records.
Add tax and business identity fields
Keep your business identity visible on the invoice, including the Company Registration / Tax Ref field when it applies to your situation. Use the linked calculator as a sanity check, but confirm tax registration, exemptions, and local rules before sending official documents.
Set payment terms and follow up
A common starting point for this guide is Net 30. Add the due date, payment instructions, and a short note about late follow-up so the client understands when action is expected.
Tax invoice or plain invoice
Only a VAT vendor registered with SARS may issue a tax invoice or charge VAT. If you are registered, the document should say "Tax Invoice" and show your VAT number, the invoice number and date, a description of the work, and the VAT amount at 15% or a statement that the total includes VAT. For larger amounts (above R5,000 at the time of writing) SARS expects a full tax invoice that also shows the client's name, address, and VAT number if they have one. If you are not registered, send a plain invoice with no VAT line and do not call it a tax invoice.
When VAT registration applies
At the time of writing, registration is compulsory once your taxable supplies pass R1 million in any 12-month period, and you can apply to register voluntarily from R50,000. SARS reviews these thresholds, so check the current figures on the SARS website or with a tax practitioner before you decide.
Rand totals and timing
Bill local clients in ZAR so the amounts match what you declare to SARS. A VAT vendor is generally expected to issue the tax invoice within 21 days of the supply, so send it when the work is delivered rather than at the end of the month.
