Egypt ETA E-Invoicing Compliance

A submission model no standard localization covers end to end

Egypt's Tax Authority does not accept a PDF. Every invoice has to be assembled into a specific JSON document, signed, submitted to the ETA platform, and then tracked through validation until it comes back accepted, accepted-with-warnings or rejected — with the returned UUID and submission reference stored against the source document. Every item on that invoice needs a code that the authority recognises: either a GS1 GTIN or an EGS code registered to your taxpayer profile. Retail sales follow a different path again, as e-receipts through the receipt API rather than the invoice API.

The standard Dynamics 365 Finance & Operations localization layer gets you part of the way. What it does not do is close the loop: build the exact document ETA expects for your document types, handle signing against your certificate, manage the item code registry, retry the submissions that fail on transport rather than content, reconcile what the portal thinks you submitted against what your ledger says you invoiced, and give an accountant somewhere to stand when a rejection comes back with a validation code and no explanation.

The result in most Egyptian F&O implementations is a manual bridge — an export, a spreadsheet, a portal upload, and a person who becomes the single point of failure for tax compliance.

What ECOSIRE builds

We build an X++ extension package for Dynamics 365 Finance and Supply Chain Management that submits directly to the ETA platform from inside F&O. Extension-only: Chain of Command, extension classes, table and form extensions, and new data entities. No overlayering.

Document assembly and signing

We map your posted documents — customer invoices, free text invoices, project invoices, credit notes and debit notes — into the ETA JSON structure, including issuer and receiver blocks, tax totals and subtypes, discount and payment structures, and the internal document reference model that links credit notes back to the original invoice. Serialization follows the canonical form the platform requires for signature validation, and the document is signed with your certificate before submission.

Item coding: EGS and GS1

We extend the released product master with an item code registry holding the code type, the code value, the effective dates and the mapping to your internal item numbers. Validation runs before posting, not after: a document that would fail on an unmapped item is caught at source with a clear message naming the item, rather than bouncing back from the authority days later. Bulk maintenance runs through the Data management framework, so onboarding thousands of items is an import, not a data entry project.

Submission, retry and status tracking

Submission runs through the batch framework — configurable batching, so you send in the volumes the platform expects rather than one document at a time. A submission record stores the request, the response, the returned UUID, the long ID, the submission reference and the validation results. Transport-level failures retry automatically with backoff; content-level rejections stop and land on an exception workspace with the authority's validation codes translated into something an accountant can act on. Nothing silently disappears.

E-receipts for retail

Where you sell through point of sale or other retail channels, receipts are assembled and submitted through the receipt path, with its own document structure, signing and status lifecycle. Receipt submission is decoupled from invoice submission so a problem in one lane never blocks the other.

Reconciliation and audit

A reconciliation view compares what the platform holds against what your ledger posted for a period, by document type and legal entity, so you find gaps before the tax authority does. Every submission, response and retry is retained as an audit trail, and the returned UUID is written back onto the source document so any invoice in F&O can be traced to its cleared counterpart.

Legal entity and dimension handling

Multi-entity is handled properly: taxpayer registration details, certificates, branch and activity codes are configured per legal entity, and ledger dimensions carry through so tax reporting reconciles to the same dimensional structure as the rest of your ledger. Where your architecture calls for it, submission telemetry can be surfaced through Power Platform or exposed over OData for a compliance dashboard.

Who this is for

Organisations invoicing in Egypt on Dynamics 365 F&O that are in scope for ETA e-invoicing and e-receipt mandates — manufacturers, distributors, retailers and services businesses with meaningful document volume, and multinational groups running an Egyptian legal entity inside a shared F&O instance where a manual portal process is not acceptable.

How delivery works

1. Scoping call. We go through your document types, your taxpayer registration and certificate arrangement, your item master and existing coding, your retail channels, and your legal entity structure.

2. Fixed quote. A written scope covering document types, coding approach, entity coverage, retry and exception handling, and acceptance criteria, at a fixed price.

3. Build. Developed in our environment against your named platform and application version, tested against the authority's preproduction environment using your own document shapes.

4. Install in test. A deployable package goes into your sandbox through LCS. We configure taxpayer details and certificates with you and run a submission cycle against preproduction so you see real acceptances and real rejections before go-live.

5. Production. After sign-off, the same package moves through your normal LCS release pipeline, pointed at the production endpoint. We stand by for the first production submission window.

6. Support. A defined post-go-live support window covering defects, with full source handed over.

This is build-to-order software. Nothing is available for instant download — the app is developed for your configuration after the quote is accepted, with a typical lead time of one working week depending on document types and entity count. Regulatory specifications change; we tell you at scoping what is covered by the fixed price and how specification updates are handled afterwards, in writing.
