Fatoora is the programme name for Saudi Arabia's mandatory e-invoicing regime, administered by ZATCA. It rolled out in two phases.

Phase 1 โ€” Generation

Invoices had to be issued electronically with prescribed fields and a QR code. Handwritten and scanned invoices stopped being acceptable.

Phase 2 โ€” Integration

The substantive phase. Invoices must be structured XML (UBL 2.1), carry a cryptographic stamp from a certificate obtained through ZATCA onboarding, and be transmitted to ZATCA โ€” cleared before issue for standard B2B invoices, reported within 24 hours for simplified B2C invoices.

Taxpayers were brought into Phase 2 in waves based on revenue, with ZATCA notifying each wave in advance.

Confirm your own wave and obligations with ZATCA or your tax advisor; this is a definition, not tax advice.
