• •July 1, 2027: Phase 2 mandatory for SMEs (below AED 50M revenue)
• •October 1, 2027: Phase 3 mandatory for government entities

Phase 1: Large Enterprises (AED 50M+ Revenue)

Phase 1 targets businesses with annual revenue of AED 50,000,000 or more. These enterprises must appoint an ASP by July 31, 2026, and achieve mandatory implementation by January 1, 2027. All B2B and B2G transactions must flow through the Electronic Invoicing System using the OpenPeppol network via an accredited ASP.

Phase 2: SMEs and Phase 3: Government Entities

Phase 2 covers small and medium enterprises with annual revenue below AED 50,000,000. SMEs must appoint an ASP by March 31, 2027, and achieve mandatory implementation by July 1, 2027. Phase 3 covers government entities, which must appoint an ASP by March 31, 2027, and implement by October 1, 2027. This phased approach is designed to allow businesses to transition gradually and smoothly. Any person may also implement the system voluntarily from July 1, 2026.

ASP Accreditation Framework

Accredited Service Providers are governed by Ministerial Decision No. 64 of 2025. ASPs must submit a formal accreditation application through the dedicated MoF portal, provide self-declaration documentation, demonstrate compliance with information security standards and the OpenPeppol interoperability framework, and obtain an operational permit before offering services. Accreditation is granted for a renewable 2-year period. Non-compliance can result in revocation with a 2-year ban on reapplication. Both invoice issuers and recipients must appoint an ASP.

How to Prepare Now

Businesses should begin their compliance journey immediately. Large enterprises (AED 50M+) face a July 31, 2026 deadline to appoint their ASP, and must be fully operational by January 1, 2027. SMEs have until March 31, 2027 to appoint an ASP and July 1, 2027 for implementation. Key preparation steps include assessing current invoicing processes, selecting an accredited ASP partner, planning system integration, training staff, and conducting thorough testing.
