E-invoicing — tax categories & reporting

The software supports standard and simplified invoices, and ZATCA’s tax categories: standard, zero-rated, exempt, out of scope — with the mandatory exemption reason for zero-rated and exempt. Credit and debit notes are linked to the original invoice. Reporting runs on a background queue so selling never stalls.

Common workflows

  1. 1

    Set the category on the item

    “Products and taxes → Taxes” — when creating or editing a tax, pick ZATCA’s category.

  2. 2

    The exemption reason

    For zero-rated or exempt, the software asks for the exemption reason before saving — ZATCA requires it.

  3. 3

    Sending behaviour

    Automatic sending is off by default — switch it on after the link is complete and tested.

  4. 4

    Credit and debit notes

    Link it to the original invoice number and write the reason for the note.
