The UAE's e-invoicing system becomes mandatory in phases from 1 January 2027, and the first deadline that actually requires action is close: businesses with annual revenue of AED 50 million or more must appoint an Accredited Service Provider by 30 October 2026.

The timeline

Annual revenue	Appoint an ASP by	Go live
AED 50 million or more	30 October 2026 (was 31 July 2026)	1 January 2027
Below AED 50 million	31 March 2027	1 July 2027

A pilot programme with selected businesses started on 1 July 2026, under Ministerial Decisions No. 243 and 244 of 2025, which set up the system and its phased rollout.

What the extension changed — and did not

In May 2026 the Ministry of Finance moved the ASP appointment deadline for the first group from 31 July to 30 October 2026, after feedback from businesses about the range of technical options and pricing available. The go-live date was not moved: large businesses still have to be issuing e-invoices through the system from 1 January 2027. The extension shortened the time between choosing a provider and going live; it did not add any.

⚠️ HEADS UP — Penalties

Failing to issue or transmit an e-invoice or e-credit note in the prescribed manner and time carries a penalty of AED 100 per document, capped at AED 5,000 per month.

What an ASP is

The UAE uses a decentralised model: invoices are exchanged and reported through accredited service providers rather than a single government portal. Your ASP connects your billing or accounting system to the network. Several accounting vendors are accredited, Tally Solutions among them — worth knowing if your books are already in Tally.

What to do before 30 October

Confirm which phase you are in from annual revenue, and keep the working.
Shortlist ASPs that work with your current system, so the appointment is not also a migration.
Clean master data now — customer TRNs, legal names and addresses — because the format is far less forgiving than a PDF invoice.
Plan the December cut-over around year-end close, not on top of it.

What stays manual

E-invoicing covers the invoice. Whether the customer paid it, paid part of it, or paid two invoices in one transfer is still answered by the bank statement — as is everything that never had an invoice: bank charges, transfers between accounts, salaries through WPS.

BankXL turns UAE bank statements into Excel or Tally XML, with AED carried through and every row checked against the running balance on the statement, so the bank side of the reconciliation starts from data you can trust. See the pages for Emirates NBD, FAB and ADCB, or the Tally Prime import guide.
