The foundation of the ECOSIRE GCC E-Invoicing Suite — a premium, country-agnostic e-invoicing engine for Gulf tax mandates. Country packs (Saudi Arabia today; Bahrain, UAE and Oman as their mandates land) plug into this engine.

Engine capabilities

• UBL 2.1 invoice builder with per-country plug-in extension points
• XAdES-BES digital signer — byte-validated against the ZATCA SDK 238-R4.0.0 reference
• TLV-encoded QR code generator (parametric per country)
• Submission orchestrator with exponential-backoff retry queue
• Hash-chained, PostgreSQL-immutable audit log (6-year tamper-evident archive)
• CSID lifecycle wizard: compliance CSID, production CSID, auto-renewal cron
• OWL dashboard with real-time KPI updates (bus.bus)
• Sandbox self-test framework (6-invoice ZATCA test matrix)
• Fernet-encrypted private-key storage with environment-variable master key

How the suite fits together

Install this engine, then add the country pack for each jurisdiction you invoice in. The Saudi Arabia pack (ECOSIRE GCC E-Invoicing | KSA ZATCA Phase 2) is available now. Try the full suite on the live demo at zatca.demo.ecosire.com.

Compatible with Odoo Community and Enterprise, versions 17, 18 and 19.
