The ZATCA E-Invoicing Compliance Connector is a build-to-order Microsoft Dynamics 365 Business Central extension that brings your posted sales documents into full compliance with Saudi Arabia's ZATCA Phase-2 (Integration / FATOORA) mandate — without ripping out your existing posting workflow.

ECOSIRE builds this as a per-tenant AL extension (not a generic AppSource download) so it maps precisely to your chart of accounts, VAT posting setup, item/branch dimensions and document numbering. We deliver table and page extensions on the Sales Invoice, Sales Credit Memo and Posted document pages, an event subscriber on OnAfterPost that serializes each document to a ZATCA-conformant UBL 2.1 XML, applies the cryptographic stamp (CSID-based digital signing), generates the TLV Base64 QR code, and submits it to the FATOORA platform's clearance/reporting APIs.

Because it runs inside Business Central, clearance status, ICV counter, PIH (previous invoice hash) and the returned QR are written back to the document and visible to your AR team. A dedicated job queue entry retries failed submissions and handles the standard vs simplified invoice flows (clearance for B2B, reporting for B2C).

ECOSIRE handles onboarding end to end: CSR generation, compliance and production CSID enrollment in the ZATCA portal, sandbox certification, then go-live on your live tenant. Multi-entity and multi-branch groups get per-VAT-registration configuration and isolated certificates.

This is an engineered, supported deliverable. After build and installation we provide a warranty period and an optional support retainer covering ZATCA schema/version changes. Pricing is a one-time USD 799 build fee. Lead time is honest and quoted up front — typically one working week depending on your invoice types and entity count.
