Egyptian merchants under the ETA mandate need every sales invoice and B2C receipt to reach the Egyptian Tax Authority in the exact JSON shape ETA expects — correctly hashed, UUID-stamped and digitally signed. Magento 2 ships nothing for this, and the cost of getting it wrong is rejected submissions and compliance exposure.

This is a build-to-order extension, not an instant Adobe Commerce Marketplace download. After you order, ECOSIRE builds the module to your store's tax configuration, item catalogue and entity registration, installs it on your environment (or hands you a tested package for your DevOps pipeline), and supports it afterward. There is no fabricated marketplace listing — you buy an engagement that ends with working code on your store.

The module is delivered as a proper composer package under app/code/Ecosire/EtaEinvoicing (or vendor/), wiring its services through di.xml service contracts, an observer on sales_order_invoice_save_after (and creditmemo/receipt events), cron jobs for retry and status polling, and admin-store-scoped configuration under System > Configuration with dedicated ACL resources. It transforms Magento invoices into ETA document JSON, computes the canonical hash, applies your digital signature (USB token / HSM or eseal-as-a-service), authenticates against ETA's OAuth client-credentials endpoint, submits, and records the returned UUID, long-ID and validation status against the order.

Works on Magento Open Source and Adobe Commerce 2.4.x. Egyptian VAT codes, the ETA GS1/EGS item-code scheme and your unit-of-measure map are configured per your business, not hard-coded. Admins get a submission grid, per-document status, error reasons from ETA, and one-click resubmit. REST and GraphQL endpoints are available for headless/PWA setups so receipts submit from any checkout.
