Odoo ships a UAE chart of accounts and a handful of 5% tax records, and for a single-entity trading company that is sometimes enough. It stops being enough the moment the Federal Tax Authority asks you to prove something. Native tax reporting gives you a report grouped by tax code, not a return laid out box by box, so someone in finance ends up rebuilding the VAT 201 in a spreadsheet every quarter from an account.move.line export. Native invoice reports are English-only, so the Arabic tax invoice requirement is met by a hand-edited Word template that drifts out of sync with the ledger. Reverse charge on imports and services from abroad is modelled as a tax with a negative repartition line if someone remembered to configure it, and nobody can explain later which lines fed which box. Designated zone movements — a free zone entity selling into the mainland, or between zones — are just ordinary invoices with the wrong tax defaulted on them. None of this is an Odoo defect; it is the gap between a generic accounting engine and a specific tax authority.

What we build is a localization module — a real Odoo addon with its own __manifest__.py, depending on account and the base UAE localization — that closes that gap inside the ERP instead of beside it. On the data side we extend account.tax and account.move with the fields the return actually needs: an FTA box mapping on the tax repartition, an emirate field on the invoice (standard-rated supplies are reported per emirate, and native Odoo has nowhere to put that), a supply-type selector that distinguishes standard-rated, zero-rated, exempt, out-of-scope, reverse-charge and designated-zone movements, and a stored computed classification on account.move.line driven by @api.depends so it recalculates when a line's tax or partner changes rather than at report time. Reverse charge is configured as a proper tax with paired repartition lines that debit output and credit input in the same journal entry, so the VAT self-accounts and both sides carry the box tag — the FTA sees a symmetric entry, and your P&L is untouched. Designated zone handling sits on the partner and the warehouse: a fiscal position with the right tax and account mappings, selected automatically through the fiscal position resolution hook when the counterparty or delivery address falls inside a zone you have flagged, so the tax on the line is correct before anyone clicks Confirm.

On the presentation side we build QWeb reports for the tax invoice, simplified tax invoice, tax credit note and self-billed invoice, each rendered bilingually with Arabic and English in the same document rather than as two separate PDFs. Arabic strings come from the standard translation layer plus the partner's lang, the layout is RTL-aware, and the mandatory fields — the words "Tax Invoice" in both languages, supplier and recipient TRNs, the tax amount in AED with its exchange rate where the invoice is in another currency, and a sequential invoice number — are asserted by the template rather than left to whoever edits the header. The VAT return preparation view is a set of read-only list and pivot views over the classified move lines, one filter per VAT 201 box, so a reviewer can open a box and see exactly the invoices behind the number before anything is filed; nothing is submitted automatically, because the return is a signed declaration and software should not sign it. Audit file export produces the FTA Audit File layout from the same classified data as a downloadable attachment, generated in a background job for large periods so the request does not time out. Access is controlled through ir.model.access.csv plus record rules, with a Tax Reviewer group that can read the return views and export, separate from the accountants who post entries. Everything is reachable over XML-RPC and JSON-RPC, so an external filing agent or a group consolidation tool can pull the same numbers the screens show.

We support Odoo 17.0, 18.0 and 19.0, and we build against the exact edition you run. That distinction matters here: Enterprise ships an accounting report engine we can extend and register the VAT 201 against as a native report definition, while on Community the same figures are delivered through the list and pivot views plus the export, because the Enterprise report engine simply is not there to build on. We tell you which you are getting during scoping, not after installation.

This product is built to order. ECOSIRE writes it against your database — your chart of accounts, your existing fiscal positions, your emirate footprint, your invoice layout, and whatever localization or e-invoicing work you already have installed — rather than shipping a generic package to force-fit. Delivery is typically 2 to 4 weeks from confirmed scope: a scoping call, then the build, then UAT on a staging copy of your production database where your accountant reconciles a real closed quarter against the return views before anything reaches production. You receive the full source, the git repository, and a support window after go-live. There is no instant download, and we do not pretend otherwise.
