ZATCA Phase 2 invoicing connected to Zoho Books

About the client

Chemtec Arabia supplies advanced chemical products to industrial customers across the Kingdom of Saudi Arabia.

The challenge

Saudi Arabia's ZATCA Phase 2 rules require invoices to be cryptographically stamped, carry a compliant QR code and be reported to the authority in near real time. Chemtec's existing setup produced English-only PDFs and could not integrate with the ZATCA platform.

• Hard regulatory deadline for Phase 2 integration
• English-only invoice templates
• No integration between invoicing and the ZATCA platform
• Manual reconciliation with Zoho Books

Our solution

1. Compliance architecture — A lightweight middleware service handles onboarding, cryptographic stamping, XML generation and clearance with the ZATCA API.
2. Bilingual templates — Arabic and English invoice layouts generated as PDF/A-3 with the embedded XML and compliant QR code.
3. Zoho Books integration — Invoices raised in Zoho Books are sent for clearance automatically, and the ZATCA response is written back to the invoice record.
4. Error handling and audit — Rejected invoices are flagged to finance with the reason, and every submission is logged for audit.

Results

Chemtec met its Phase 2 deadline with a fully automated, auditable invoicing process.

• 100% of invoices cleared through ZATCA without manual steps
• Bilingual invoices accepted by all key customers
• Finance reconciliation time reduced significantly
• Complete audit trail for every invoice
