What is required
Phase 2 means real-time integration.
ZATCA rolled out e-invoicing in Saudi Arabia in two phases. Phase 1 (from December 2021) required electronic generation. ZATCA Phase 2, the integration phase, has been rolling out in waves since January 2023, grouped by revenue, with taxpayers notified ahead of their deadline.
In Phase 2, your system must produce invoices in UBL 2.1 XML, sign them with a cryptographic stamp, add a QR code and send them to Fatoora: standard tax invoices for clearance before issue, simplified invoices for reporting within 24 hours.
- XML generation: UBL 2.1 with the ZATCA data dictionary
- Cryptographic stamping: with your CSID certificates
- Clearance & reporting: via the Fatoora APIs
- Error handling: retries, logs and rejection alerts

Buyer guide
ZATCA Phase 2: the questions we hear most.
How do I know my deadline?
ZATCA notifies taxpayers in each wave in advance of their integration deadline, based on revenue thresholds. Check the ZATCA e-invoicing regulations and the notifications for your VAT number, and start integration as soon as you are notified.
Can my current ERP do this?
Many ERPs offer a ZATCA module, but it often needs configuration, master data fixes and testing. Older or custom systems usually need an integration layer, which we build.
What does ZATCA integration cost?
Configuring an ERP that already supports Phase 2 usually costs $1,500 to $5,000. Building an integration for a custom or legacy system typically costs $5,000 to $15,000.

FAQ
ZATCA E-Invoicing questions, answered.
Straight answers to what clients ask us most. Still curious? Ask us on WhatsApp.
What is ZATCA Phase 2?
It is the integration phase of Saudi e-invoicing (Fatoora). Invoices must be generated in XML, cryptographically stamped and sent to ZATCA for clearance (B2B) or reporting (B2C).
Do simplified invoices need clearance?
No. Simplified (B2C) invoices are reported to ZATCA within 24 hours of issue. Standard (B2B) tax invoices must be cleared before they are shared with the buyer.
What is a CSID?
A Cryptographic Stamp Identifier is the certificate ZATCA issues to each invoicing unit. It is used to sign invoices and must be renewed before it expires.
Can you integrate Odoo or ERPNext with ZATCA?
Yes. We configure Odoo's Saudi localization or a ZATCA app for ERPNext, then test and onboard it.
Do you support businesses outside Saudi Arabia?
Yes. If you are VAT-registered in Saudi Arabia but run systems elsewhere, we integrate your systems with ZATCA remotely.
