ZATCA compliance · Saudi Arabia
ZATCA Phase 2 e-invoicing integration for your ERP
We make your ERP or POS FATOORA-compliant: generating UBL 2.1 XML invoices with QR codes and cryptographic stamps, onboarding your devices, and connecting to ZATCA for clearance and reporting.
- Phase 1 and Phase 2 compliance
- UBL 2.1 XML, QR codes and cryptographic stamping
- Device onboarding (CSID) handled for you
- Clearance and reporting through ZATCA's APIs
Who it's for
Who must comply?
E-invoicing applies to all VAT-registered persons in the Kingdom. Phase 2 (integration) is being rolled out in waves:
- Every VAT-registered business must issue electronic invoices (Phase 1)
- Businesses are selected for Phase 2 in waves based on their taxable revenue
- ZATCA notifies each selected taxpayer in advance of its integration deadline
- Businesses that have been notified must integrate their systems with FATOORA by their deadline
Phase 1 vs Phase 2
Phase 1: Generation
Since December 2021, invoices must be generated and stored electronically by a compliant solution, with a QR code on simplified (B2C) invoices. Handwritten and editable invoices are no longer accepted.
Phase 2: Integration
From January 2023, in waves, your system must connect to ZATCA's FATOORA platform. Invoices are produced in UBL 2.1 XML with a cryptographic stamp and submitted to ZATCA.
Clearance (B2B)
Standard tax invoices must be cleared by ZATCA before they are shared with the buyer.
Reporting (B2C)
Simplified tax invoices are issued to the customer immediately and reported to ZATCA within 24 hours.
Phase 2 technical requirements
A compliant solution must, among other things:
- Generate invoices, credit and debit notes in UBL 2.1 XML format
- Apply a cryptographic stamp and invoice hash chain to every document
- Produce the required QR code on invoices
- Onboard each invoicing device or unit with ZATCA to obtain a Cryptographic Stamp Identifier (CSID)
- Connect to ZATCA's APIs for clearance and reporting, and handle rejections
- Keep invoices tamper-proof and archived for the required retention period

Frequently asked questions
How do I know when my business must integrate?
ZATCA notifies selected taxpayers in advance of their Phase 2 deadline, based on revenue thresholds for each wave. Check your notification or the FATOORA portal, and contact us early to leave time for testing.
Can you make our existing ERP compliant?
In most cases, yes. We add a ZATCA integration layer to your current ERP or POS instead of replacing it.
What is a CSID and who obtains it?
A Cryptographic Stamp Identifier is issued by ZATCA to each onboarded invoicing unit. We handle the onboarding process with an OTP from your FATOORA portal.
What happens if ZATCA rejects an invoice?
Our integration shows the rejection reason, alerts your team and lets you correct and resubmit the document.
Do you support Arabic invoices?
Yes. Invoices can be produced in Arabic or bilingual Arabic and English formats.
