ZATCA-Compliant POS E-Invoice (KSA)

The module extends Odoo's native POS and account.move flow so that closing a POS order generates a ZATCA-compliant simplified tax invoice (B2C) carrying the mandatory TLV-encoded, Base64 QR — seller name, VAT number, timestamp, invoice total and VAT amount, plus the Phase-2 hash and cryptographic stamp fields. The QR is rendered both on the thermal-printed receipt and on the QWeb PDF, and the receipt is bilingual (Arabic and English) with a correct VAT breakdown per line and per rate. Behind the scenes we implement the EGS (E-invoice Generation Solution) onboarding: CSR generation, compliance CSID and production CSID, and the clearance/reporting calls to the Fatoora APIs — first against the sandbox, then against production once your device is certified.

Everything is grounded in real Odoo architecture. We add fields and compute methods (models.Model, fields, @api.depends) to carry ZATCA state on pos.order and account.move; a QWeb report template for the compliant PDF invoice; automated actions / cron (ir.cron) to retry failed reporting; and proper security via ir.model.access.csv plus record rules so only the right POS and accounting roles can view or resubmit invoices. Integration with the Fatoora reporting endpoint is done server-side and can also be triggered over Odoo's JSON-RPC/XML-RPC API for headless flows. The module targets Odoo 17, 18 and 19 and works on both Community and Enterprise (Enterprise gives you the richer POS and accounting UX; we confirm parity for your edition during scoping).

You get a licensed, documented module tailored to your legal entity, VAT registration and multi-branch/multi-journal setup — not a generic checkbox. ECOSIRE handles the ZATCA onboarding paperwork alongside you, trains your cashiers and finance team, and stands behind the delivery with a post-launch support window and updates as ZATCA specifications evolve.
