UAE e-invoicing deadlines 2026–2027: who must act, and by when

The UAE is rolling out mandatory e-invoicing on the Peppol "5-corner" model. Invoices will no longer travel directly from supplier to customer — they pass through Accredited Service Providers (ASPs) on both sides, with tax-authority reporting built in. Appointing an accredited ASP is therefore a compliance obligation with fixed deadlines, not an optional upgrade.

The four dates

What "appoint" actually involves

Appointing an ASP is more than signing a form. In practice a business needs to:

1. Shortlist providers from the official accredited register (48 accredited providers as of 1 September 2026) — only accredited providers count.
2. Compare on facts, not marketing — pricing, integration with your accounting system, onboarding time, multi-TRN support, contract exit terms. Almost no provider publishes these; you have to ask. Our 12-question checklist covers what to settle in writing.
3. Sign and integrate — connect the ASP to your ERP or invoicing process, test, train the finance team.
4. Go live before your deadline — allowing for the provider's real onboarding time, which ranges from days to months depending on your systems.

Who should care right now

• Large businesses (≥ AED 50M): your appointment window is measured in weeks. Shortlist now.
• SMEs: your date is 31 March 2027 — but the good providers' onboarding queues will fill as the first deadline passes.
• Accounting & bookkeeping firms: every client on your books will face this choice and most will ask you. Firms that answer with provider-confirmed data turn a compliance question into an advisory service.
