How does invoice numbering work?

Numbers are assigned when you issue, not when you start a draft, so the series is consecutive with no gaps.

SARS expects a unique, consecutive series, and gaps or duplicates are a red flag in an audit.

Klaar therefore hands out a number only at the moment you issue the document. An abandoned draft never burns a number, and two people pressing Send at the same instant cannot land on the same one.

Quotes and credit notes run in their own separate series. You can change the prefix under Settings, but not the numbers themselves.

• Why can I not edit an invoice after sending it?
• Can I send a quote first?
• I bill the same client the same thing every month
• Where do I put my bank details?

If not, the assistant in the corner can dig further, or a person will pick it up by email — Mon to Fri, 08:00 to 17:00 SAST.
