What is ZATCA e-invoicing in Saudi Arabia?

ZATCA (Zakat, Tax and Customs Authority) e-invoicing is the mandatory digital invoicing system in Saudi Arabia, known as Fatoorah. It requires all VAT-registered businesses to generate structured XML invoices with digital signatures. Phase 1 (Generation) started December 2021; Phase 2 (Integration/Clearance) has been rolling out in waves since January 2023.

What is the difference between ZATCA Phase 1 and Phase 2?

Phase 1 (Generation Phase) requires businesses to generate structured XML invoices with a QR code on every B2C invoice, stored in ZATCA-compliant format. Phase 2 (Integration Phase) requires real-time clearance for B2B invoices and reporting for B2C invoices through a direct API integration with ZATCA's Fatoorah platform.

How does ROSTAN integrate ZATCA e-invoicing with Oracle EBS?

ROSTAN has a pre-built Oracle EBS ZATCA connector that intercepts invoice creation in the AR module, generates the UBL 2.1 XML with cryptographic stamp, submits it to ZATCA for clearance in real-time, and writes back the ZATCA-cleared invoice reference to EBS — all without manual intervention.

What is the ZATCA Phase 2 integration timeline for my company?

ZATCA is onboarding companies in waves based on annual revenue. Large enterprises (above SAR 3 billion) were in early waves; smaller businesses are being onboarded progressively. ROSTAN can help you check your wave assignment and ensure you're compliant before your deadline.

What is a CSID in ZATCA e-invoicing?

CSID (Compliance Stamp Identifier) is a cryptographic certificate issued by ZATCA to each registered taxpayer. Every invoice must be stamped with the CSID before submission. ROSTAN handles the CSID onboarding, certificate management, and renewal process for you.

Does ROSTAN support ZATCA e-invoicing for businesses in Riyadh and Jeddah?

Yes. ROSTAN serves Saudi businesses across all major cities — Riyadh, Jeddah, Dammam, Al Khobar, Mecca, Medina, and NEOM. We provide remote implementation and on-site support across the Kingdom of Saudi Arabia.

In short

ZATCA e-invoicing in Saudi Arabia runs in two phases: Phase 1 (generation) requires structured electronic invoices with a QR code, and Phase 2 (integration) requires invoices to be cleared or reported through ZATCA's Fatoora platform with cryptographic stamping. Clearance failures are usually traced back to the ERP rather than the platform — customer and tax master data, VAT treatment, or a payload that does not validate. ROSTAN integrates Phase 2 clearance directly into Oracle EBS and Fusion Receivables for Saudi entities.
