Egypt's Tax Authority (ETA) mandate requires every registered business to issue structured e-invoices — and, for B2C retail and restaurant sales, e-receipts — that are digitally signed, carry a unique UUID, and are submitted to the ETA platform in real time. Business Central does not do this natively, and the JSON schema, signing, and submission lifecycle are non-trivial.

This is a build-to-order extension. ECOSIRE builds it in AL against your specific Business Central setup, installs it as a per-tenant extension on your environment (cloud or on-prem), and supports it after go-live. It is not an instant AppSource download — it is a tailored solution delivered and maintained by our team.

The extension generates ETA-compliant e-invoice and e-receipt documents from your posted Sales Invoices and POS transactions, maps your items, tax codes, and customers to ETA code structures (GS1/EGS, tax type and subtype tables), applies the required digital signature (CADES / HSM or USB token, as your compliance path dictates), assigns and stores the UUID, and submits to the ETA portal via its REST API. Submission status is tracked on each document with valid / invalid / rejected states, human-readable error reasons, and one-click retry. A scheduled Job Queue handles batched submission and status polling so your team never babysits the portal.

We deliver Arabic and bilingual invoice/receipt templates, dedicated permission sets, document and ledger extensions, event subscribers wired into BC's posting routines, and a clear setup page for credentials and environment switching (preproduction vs production ETA). Optional Power Platform / Dataverse surfacing of submission status is available for dashboards and approvals.
