What is ZATCA Phase 2? The Integration Phase Explained
ZATCA Phase 2 — the Integration phase — started on 1 January 2023. Where Phase 1 was about generating e-invoices, Phase 2 is about connecting your invoicing system directly to ZATCA through the FATOORA platform.
What changes in Phase 2
- Invoices are produced in a structured XML format (or PDF/A-3 with embedded XML).
- Standard (B2B) invoices are sent to ZATCA for clearance in real time — the invoice is only valid after ZATCA stamps it.
- Simplified (B2C) invoices are reported to ZATCA within 24 hours of issue.
- Each invoice carries a cryptographic stamp, UUID and invoice counter, forming an unbreakable chain.
Who must comply, and when?
Phase 2 is rolled out in waves by annual revenue. ZATCA notifies each targeted group at least six months before their integration date — see our full roll-out waves timeline.
Getting ready with Zenvy POS: your invoice data — QR codes, VAT breakdowns, credit notes and sequential numbering — is already structured the way FATOORA integration expects, so moving to Phase 2 when your wave arrives is a configuration step, not a system change.
