If your business is in the AED 50 million-plus implementation band, check whether you must appoint an Accredited Service Provider (ASP) by 30 October 2026. Mandatory e-invoicing for you starts on 1 January 2027 — and that date has not moved.
What is changing
October 2026 update: Ministerial Decision No. 197 of 2026 changed certain e-invoicing rules for tax-group transactions, data retention and system-failure notification. The ASP appointment deadline and first mandatory implementation date remain as announced by the Ministry of Finance.
Under Ministerial Decisions No. 243 and 244 of 2025, B2B and B2G invoices in the UAE will no longer go directly from supplier to customer. They will flow through accredited service providers on the Peppol network, with invoice data reported to the FTA in near real time. B2C transactions are outside the mandatory scope for now.
Key dates
| Entity | Appoint ASP by | Go live |
|---|---|---|
| Revenue AED 50 million or more | 30 October 2026 | 1 January 2027 |
| Revenue below AED 50 million | 31 March 2027 | 1 July 2027 |
| Government entities | 31 March 2027 | 1 October 2027 |
A voluntary pilot has been open since 1 July 2026 for businesses that want to test early.
Penalties and implementation
- Failure to appoint an ASP or implement the system on time: AED 5,000 for each month of delay.
- Failure to issue and transmit an e-invoice on time: AED 100 per invoice, capped at AED 5,000 a month.
- Late notification of changes to data recorded in the system can attract a daily penalty under the applicable decision. Check the precise obligation and period.
Why smaller businesses should start now
E-invoicing is not a software switch. Your customer master data, TRNs, item codes and invoice formats must be clean before an ASP can connect your system. Businesses below AED 50m have until 31 March 2027 to appoint an ASP under the current timetable — a short window once year-end closing starts.
What to do now
- Confirm which revenue band your business falls into.
- Shortlist accredited ASPs and check they integrate with your accounting software.
- Clean up customer and supplier TRN data.
- Train your finance team on the new invoice flow.
