UAE E-Invoicing Compliance Software

The UAE e-invoicing mandate timeline

The rollout is phased by revenue under Ministerial Decision No. 56 of 2026, and penalties for non-compliance run up to AED 5,000 per non-compliant invoice. These are the dates that matter:

1. 1 July 2026Pilot phase opens

   The UAE e-invoicing pilot is live. Early movers are already exchanging structured invoices.

2. 30 October 2026ASP appointment deadline — revenue ≥ AED 50M

   Businesses with annual revenue of AED 50M or more must appoint an Accredited Service Provider under Ministerial Decision No. 56 of 2026.

3. 1 January 2027Compliance mandatory — large businesses

   Businesses with revenue ≥ AED 50M must issue and report e-invoices through their ASP.

4. 31 March 2027ASP appointment deadline — all other businesses

   Smaller businesses must have their Accredited Service Provider appointed by this date.

5. 1 July 2027Compliance mandatory — all other businesses

   The mandate reaches every in-scope business in the UAE.

What PINT-AE and UBL 2.1 mean — and what Invaq generates

The UAE mandate is built on structured XML, not PDFs. UBL 2.1 is the underlying document vocabulary; PINT-AE is the UAE localization of the Peppol international invoice profile that defines exactly which fields, codes, and totals a compliant invoice must carry. Invaq normalizes every invoice into a single canonical record, then renders it as PINT-AE-aligned UBL 2.1 XML deterministically — what you submitted is always exactly what you can re-inspect later.

• Correct UBL document types per UNCL1001: commercial invoice (380), credit note (381), debit note (383) — each with the right root element and references back to the original invoice.
• Full party detail on both sides: legal names, addresses, and 15-digit TRNs rendered into AccountingSupplierParty and AccountingCustomerParty.
• TaxTotal and LegalMonetaryTotal computed from the same canonical amounts the validation engine checks — the XML can never disagree with what was validated.
• Every interpolated value is XML-escaped, so invoice content can never break or inject into the document structure.

A deterministic validation engine with a 0–100 score

A pure, deterministic rule engine checks every invoice before it can move forward — same input, same verdict, every time. Nothing reaches an ASP unvalidated, and every verdict comes with stored evidence you can hand to an auditor.

• Line-level math: quantity × unit price reconciliation, VAT per line, and category rate enforcement (Standard 5%, Zero-rated, Exempt, Out of scope).
• Totals reconciliation including the per-category VAT breakdown computed on the aggregated base (BR-CO-17), with rounding tolerances that match the standard.
• Duplicate invoice-number detection per legal entity, and mandatory original-invoice references on credit and debit notes.
• Your own workspace policies — PO required, value limits, custom required fields — layer on top and can only make validation stricter, never looser.
• Every run produces a 0–100 score and a persisted evidence record, kept separately from the invoice so re-validation never overwrites history.

The ruleset is a versioned draft (uae-pint-ae-draft-1) of the PINT-AE requirements, updated as the official regulator specification is finalized.

ASP routing without lock-in

Under the UAE model, invoices reach the tax authority through Accredited Service Providers. Invaq treats the ASP as a pluggable adapter behind one interface, so switching or adding providers never touches your invoice, validation, or audit machinery.

• One adapter interface per provider: your invoices, workflows, and audit history never depend on any single ASP.
• Submissions run asynchronously with automatic retries — a provider outage delays delivery, it never loses an invoice.
• Failed submissions land in the Exceptions center with the real error, where they can be retried individually or bulk-fixed by root cause.
• Every attempt, success, and failure is written to the audit trail with the provider message ID.

Honest footnote: the Ministry of Finance pre-approved ASP list currently names 42 providers, and none is fully accredited yet. Live provider connections switch on as the FTA finalizes accreditation — the routing, retry, and audit machinery around them is already running.

Trust Ledger: software that can prove what it did

Most audit logs ask you to trust that nobody edited them. Invaq’s can prove it.

• Each audit event stores a SHA-256 hash of its own canonical content combined with the hash of the event before it — an unbroken chain from the very first record.
• Editing, deleting, or reordering any past event breaks every hash after it. Tampering is mathematically evident, not just policy-forbidden.
• One-click verification re-computes the entire chain and reports exactly where, if anywhere, it breaks.
• The FTA audit pack export bundles the XML documents, validation evidence, and the chain-integrity report into a ZIP for any date range — a self-proving compliance package.

Multi-currency, and invoice numbers that cannot collide

And the rest of the platform

• Document vault — encrypted storage for VAT certificates, trade licenses, and correspondence, attached per entity or supplier.
• Vendor portal — external suppliers self-manage their own profile and documents, scoped to exactly one supplier record.
• AI CSV mapper — import from any ERP — an LLM proposes the column mapping, you confirm it, then it imports for real.
• API keys + HMAC webhooks — role-scoped server-to-server keys and signed outbound webhooks so your systems react the moment an invoice moves.
• Executive reports — CFO-level tax liability, validation pass rate, and per-entity breakdowns, normalized to AED.

Invaq also plans and evidences your ICV score and runs a consent-enforced CRM on the same audited rails.
