Article 5 of Ministerial Decision No. 243 of 2025 establishes the Accredited Service Provider appointment as a legal obligation for every Issuer and Recipient within the scope of the Electronic Invoicing System. It is not a technical option or a market choice between certified and uncertified intermediaries. An Issuer or Recipient who routes electronic invoices through any intermediary that is not on the Ministry-published list of Accredited Service Providers has not satisfied this obligation, regardless of the intermediary's technical capability or Peppol certification status in other jurisdictions.
Clause 1: The Obligation and Its Scope
Article 5(1) provides: "Without prejudice to the Issuer's and Recipient's obligations under this Decision, the Issuer and the Recipient, as applicable, shall appoint an Accredited Service Provider in accordance with Article 6 of this Decision."
The phrase "without prejudice to the Issuer's and Recipient's obligations" is a critical qualifier. The ASP appointment does not transfer or extinguish the Issuer's or Recipient's own compliance obligations. An Issuer who appoints an accredited provider but fails to ensure that the provider transmits invoices within the 14-day window remains in breach of Article 6(5). The ASP provides the technical pathway; the obligation to use that pathway correctly remains with the Issuer and Recipient. This distinction matters when assessing the contractual terms of ASP service agreements: SLA commitments, liability for failed transmissions, and error notification procedures all need to be mapped against the legal obligations that the Issuer and Recipient personally carry.
Clause 2: The Published List
Article 5(2) requires the Ministry to publish the list of Accredited Service Providers. This list is the definitive source. An intermediary's claims about its own accreditation status are not a substitute for verification against the Ministry-published list. The Ministry's EmaraTax portal and e-invoicing section of the MoF website are the primary sources for the published list. Businesses should verify ASP status at the time of appointment and periodically during the term of the service agreement — accreditation can be suspended or withdrawn under MD 64 of 2025 if a provider fails to maintain compliance with accreditation requirements.
Clause 3: The Notification Obligation on Data Changes
Article 5(3) creates a specific data notification obligation that is easy to overlook in the broader implementation workload: "The Issuer and the Recipient shall notify the appointed Accredited Service Provider in writing of any change to the data registered with the Authority pursuant to Clause 4 of Article 6 of the Cabinet Decision No. 74 of 2023 on the Executive Regulation of the Tax Procedures Law, within five Business Days from receiving confirmation of the amendment by the Authority."
Article 6(4) of Cabinet Decision No. 74 of 2023 covers the data elements that a registrant must maintain with the FTA — including legal name, trade licence details, address, and related registration information. When any of this information changes and the Authority confirms the amendment on EmaraTax, the five-Business-Day notification clock to the ASP starts running. This creates an operational link between the FTA registration maintenance process (which typically sits with the tax or finance team) and the ASP service relationship (which typically sits with the IT or procurement team). Businesses need an internal workflow that connects these two functions so that FTA-confirmed data changes trigger the ASP notification automatically, not on an ad hoc basis.
The ASP Appointment Timeline Under MD 244
Article 5 of MD 243 sets the obligation; Article 5 of MD 244 sets the timing. For Phase 1 businesses — those with Revenue of AED 50 million or above — the ASP appointment deadline is 31 July 2026. For Phase 2 businesses, the appointment deadline is 31 March 2027. Government Entities must appoint by 31 March 2027. These appointment deadlines precede the go-live implementation dates by five to six months, giving businesses a structured window for integration before mandatory live exchange begins.
The appointment is made through EmaraTax. The process involves linking the legal entity's EmaraTax account to the chosen ASP, which provisions the Peppol Participant Identifier for that entity. A corporate group with multiple in-scope UAE legal entities must complete a separate appointment for each entity — there is no group-level appointment mechanism that covers multiple entities simultaneously.
Selecting the ASP: What Article 5 Does Not Say
Article 5 establishes the obligation but not the selection criteria beyond accreditation. The ASP selection decision is one of the most consequential choices in the e-invoicing implementation programme, and it involves assessment along dimensions that MD 243 leaves entirely to the market: integration method (API-based, file-based, or ERP-native connector), data processing location and storage within the UAE, service levels for transmission confirmation and error handling, support for inbound invoice processing and confirmation messaging, pricing model and contractual flexibility, and the provider's financial stability and operational track record. These are contractual and commercial questions, not regulatory ones. But they materially affect the quality and sustainability of compliance, and they cannot be resolved in the last weeks before the appointment deadline.
