If your business falls within the scope of UAE e-invoicing, you cannot connect your accounting system directly to the Federal Tax Authority (FTA). Every Electronic Invoice must first pass through an Accredited Service Provider (ASP), the FTA-approved intermediary that validates, converts and transmits your invoice data. Completing ASP onboarding correctly, and on time, is now a compliance requirement.
This checklist explains who needs to onboard an ASP, the documents you need ready, how to choose an accredited provider, and the exact steps to get connected.
What is an ASP in the UAE e-Invoicing System?
The UAE has adopted a 5-corner Decentralised Continuous Transaction Controls (DCTC) model:
- Corner 1: the Supplier
- Corner 2: the Supplier’s ASP
- Corner 3: the Recipient’s (buyer’s) ASP
- Corner 4: the Recipient (buyer)
- Corner 5: the Federal Tax Authority
An ASP is an organisation authorised by OpenPeppol to access the Peppol Interoperability Framework, and separately accredited by the UAE Ministry of Finance under Ministerial Decision No. 64 of 2025. Your business appoints one ASP to handle both sending (accounts receivable) and receiving (accounts payable) Electronic Invoices. The ASP validates your Electronic Invoice data, converts it into the mandatory XML format under the PINT-AE billing specification, and reports the required Tax Data to the FTA on your behalf.
Who Needs to Complete ASP Onboarding, and By When?
Electronic Invoicing is mandatory for any Person conducting Business in the UAE, regardless of VAT registration status, unless specifically excluded. The Ministry originally set a phased rollout under Ministerial Decision No. 244 of 2025, and in May 2026 extended the first-wave ASP appointment deadline in response to market feedback on provider choice and pricing.
The current timeline is:
- Persons with Annual Revenue AED 50,000,000 or more: ASP Appointment Deadline is 30 October 2026. and deadline for Einvoicing implementation is 1 January 2027.
- For Persons Below AED 50,000,000: ASP Appointment Deadline is 31 March 2027 and Einvoice implementation deadline is 1 July 2027
- For Government Entities: ASP Appointment Deadline is 31 March 2027 and Einvoice implementation deadline is 1 October 2027
Documents and Information to Prepare Before Onboarding
Before you approach an ASP, gather the following:
- A valid trade licence and company registration details
- Your Tax Identification Number (TIN): the first 10 digits of your Tax Registration Number (TRN). If you are within scope but not registered for any tax type, you must register with the FTA to obtain a TIN
- Authorised signatory and EmaraTax account admin details
- Details of your accounting/ERP/invoicing system, including whether it can generate data compatible with the PINT-AE XML format
- A designated technical contact to manage the integration and testing process
- For Tax Group members: each entity’s own TIN, since each Tax Group member must onboard individually and may use a different ASP
How to Choose an FTA-Accredited ASP
The Ministry of Finance maintains a Central Register of Accredited Service Providers, accessible via EmaraTax. Under Ministerial Decision No. 64 of 2025 (as amended), an accredited ASP must demonstrate:
- Active Peppol certification and successful completion of OpenPeppol conformance testing
- At least two years’ experience operating the relevant Peppol Service Provider (PSP) product
- Minimum paid-up capital of AED 50,000 and a valid trade licence
- ISO/IEC 27001 certification for the PSP product, plus multifactor authentication and encryption of data in transit and at rest
- ISO 22301 business continuity certification
- Professional indemnity insurance (minimum AED 2,500,000), crime insurance and cyber fraud insurance (minimum AED 5,000,000 each)
- A commitment to provide 100 free eInvoice exchange and reporting services per End User annually
When comparing shortlisted ASPs, also weigh:
- Compatibility of their integration method (direct API, Peppol access point or middleware) with your existing ERP
- Their sandbox/testing environment and average onboarding timeline
- Service Level Agreement (SLA) terms, including uptime and how transmission failures are handled and escalated
- Support availability in English and Arabic, and whether they offer local implementation assistance
Step-by-Step ASP Onboarding Process
Onboarding must be initiated by your business (not the ASP) via the EmaraTax portal. The process follows four broad steps:
- Understand your obligations confirm your mandatory implementation phase, review the data points required for each Electronic Invoice category relevant to your transactions, and check whether your accounting/ERP system needs upgrading.
- Select and connect to an ASP: log into EmaraTax, open the E-Invoicing tile, review the list of Accredited Service Providers, and select “Proceed to ASP” to be redirected to your chosen provider’s onboarding portal. Finalise your commercial contract with the ASP and obtain your Peppol Participant Identifier (0235 followed by your 10-digit TIN).
- Test invoice exchange and reporting: agree with your ASP how invoice data will be transmitted, then run end-to-end sandbox testing of Electronic Invoice issuance, receipt, and Tax Data reporting to the FTA.
- Go live: agree roles and responsibilities with your ASP for ongoing transmission oversight and error resolution, then commence live exchange and reporting of Electronic Invoices.
Sandbox testing sign-off is a required step before go-live, it is not optional, and skipping or rushing it is one of the most common reasons businesses miss their deadline.
What Commonly Delays ASP Onboarding
- A TIN that is inactive, not yet generated, or linked to the wrong legal entity
- ERP software that cannot yet generate data mapped to the PINT-AE / UBL 2.1 structure, requiring a system upgrade first
- Missing authorisation documents where a tax agent or implementation partner is managing onboarding on your behalf
- Underestimating the time needed to reconfigure approval workflows around the Electronic Invoicing System
- Leaving ASP selection until close to the statutory deadline, with no buffer for testing or error resolution
Penalties for Missing Your ASP Onboarding Deadline
Once your mandatory implementation date passes without a working ASP connection, both administrative penalties (under the VAT Decree-Law and Tax Procedures Law framework) and specific Electronic Invoicing penalties under Cabinet Decision No. 106 of 2025 can apply. Penalties do not apply to invoices issued voluntarily before a business’s mandatory date, which is precisely why early, phased onboarding is the lower-risk route.
FAQs
Can a business use more than one ASP at the same time?
Generally, each Person should appoint a single ASP for both sending and receiving Electronic Invoices. Members of a Tax Group, however, are onboarded individually and each member may select a different ASP, since each holds its own TIN.
What happens if my chosen ASP loses its accreditation?
The Ministry delists a terminated ASP from the Central Register and notifies OpenPeppol. Your business would need to migrate to another accredited provider to keep transmitting Electronic Invoices without interruption.
Is there a fee to register on the FTA e-invoicing portal?
Registering your TIN and onboarding via EmaraTax does not carry an FTA fee. ASPs set their own commercial pricing for integration and ongoing service, which varies by provider and by the complexity of your ERP integration.
