A UAE eInvoicing project can stall even when a business has chosen an Accredited Service Provider (ASP). The finance team understands the invoices, tax understands the treatment, IT understands the connections, and the ERP team knows where the data is created. If these teams work separately, gaps often surface during testing.
The practical solution is to assign one project owner and give each team a clear deliverable. Your ASP is an essential external participant, but your business still needs to prepare its processes, data, systems, and staff.
Who should be on a UAE eInvoicing project team?
A useful core team includes an executive sponsor, project lead, finance owner, tax owner, IT owner, and ERP owner. Add an accounts payable representative if receiving supplier invoices is handled separately. Bring your chosen ASP into planning and testing once the integration approach is agreed.
One person can fill more than one role in a smaller business. What matters is that every decision and task has a named owner.

This is a suggested project structure, not a list of job titles prescribed by the UAE government. The Ministry of Finance guidance sets out the obligations and preparation steps; each business can organise its team to deliver them.
1. Give finance ownership of the invoice process
Finance knows how transactions actually move through the business. Ask the finance owner to list where invoices originate and what happens before and after they are issued.
That list should include standard sales invoices, commercial invoices where relevant, credit notes, advance payments, recurring bills, project or milestone invoices, exports, and intercompany charges where applicable. It should also cover incoming supplier invoices: who receives them, matches them to purchases, approves them, and deals with exceptions.
The output should be a set of real examples for testing. A technically successful test using only one simple invoice does not prove that returns, discounts, or unusual customer cases will work.
2. Ask tax to approve the rules and exceptions
The tax owner should review how each transaction is classified and which invoice or credit note category is appropriate. This includes the business’s VAT treatments, zero-rated or exempt supplies where relevant, and the information required on different documents.
Tax should also help determine which transactions are within the current UAE eInvoicing scope and identify cases that need specialist review. Finance and tax should sign off the scenario list before the ERP team finalises field mapping. Otherwise, a technically correct integration could repeatedly transmit the wrong tax classification.
Keep a short decision register. If a tax treatment changes during the project, the team can see which ERP rule, test case, and ASP mapping must be updated.
3. Give IT ownership of the connection and support plan
IT should agree with the ERP provider and ASP how invoice data will move, how acknowledgements will return, and who can access each system. The review should cover credentials, permissions, secure transmission, monitoring, and the handling of failed or delayed messages.
The Ministry’s guidance specifically calls for businesses to agree with their ASP how data is transmitted, how success or failure confirmations are received, and how incoming electronic invoices reach the business. It also calls for a process to resolve errors before go-live.
A useful IT deliverable is a simple support runbook: what failed, where it failed, who investigates first, and who confirms that it has been resolved.
4. Involve the ERP team from the beginning
Most invoice information starts in the ERP. Customer and supplier details, item descriptions, amounts, tax codes, invoice types, and credit note references must be available and mapped correctly before data reaches the ASP.
Ask your ERP owner or provider to compare existing fields and workflows with the required electronic invoice data. Identify missing information, data-cleaning work, configuration changes, and any custom integration. Then test both sending and receiving, including the status messages returned by the ASP.
For a FactsERP customer, FACTS can work with finance, tax and IT to review the current setup, identify gaps, prepare the relevant data and document flows, and support integration testing with the selected ASP. FactsERP is the business system feeding the process; the appointed ASP performs its own accredited exchange and reporting role.
5. Bring the ASP into end-to-end testing
Selecting an ASP is a milestone, but a contract alone does not make the business ready. Agree who will provide the test environment, sample files or API specifications, validation feedback, and confirmation messages.
Test the complete journey:
Create an invoice from an actual business scenario in the ERP.
Send the required data to the ASP.
Check validation and exchange with the buyer.
Receive and record the success or failure acknowledgement.
Confirm the required tax data reporting status.
Correct a deliberately rejected invoice and retest.
Receive and process a supplier’s electronic invoice.
Repeat for credit notes and other important transaction types.
The Ministry’s readiness checklist includes ERP changes, integration, exchange and reporting tests, and a governance model for resolving errors. Your project lead should keep evidence of the results and the owner of each unresolved issue.
Who makes the final go-live decision?
The executive sponsor should approve go-live using evidence from the workstream owners. Finance confirms that the operating process works. Tax confirms that the agreed scenarios and mappings were tested. IT confirms that connections and monitoring are ready. The ERP owner confirms that source data and workflows behave as expected. The ASP confirms its onboarding and exchange arrangements.
A short go-live checklist can cover:
Are the relevant invoice and credit note scenarios tested?
Are customer and supplier records ready?
Can staff see failed submissions and know what to do?
Are incoming electronic invoices handled?
Is there an owner for unresolved errors and a route to the ASP?
Has the team agreed how to manage changes after launch?
Work backwards from your applicable deadline
Businesses in scope with revenue of AED 50 million or more must appoint an ASP by 30 October 2026 and implement eInvoicing by 1 January 2027. The 30 October date was set by the 2026 amendment to the original implementation decision.
For businesses in scope below AED 50 million, the published dates are 31 March 2027 to appoint an ASP and 1 July 2027 to implement. In-scope government entities have a separate implementation timetable. Confirm your category against the latest official Ministry of Finance eInvoicing portal.
Set internal dates for scope review, data clean-up, ASP selection, ERP changes, testing and staff training before the mandatory date. Leave time to fix the cases that fail in testing.
Start with one working session
Bring finance, tax, IT, the ERP owner and the project lead into a single meeting. Take three real invoices and one credit note. For each document, ask:
Why was it issued, and who approved it?
Which system created each piece of data?
Is the customer and tax information complete?
How will it reach the ASP?
How will the team know whether exchange and reporting succeeded?
Who will correct it if the ASP rejects it?
That session will reveal more useful work than a generic project plan built without seeing the invoices.
FACTS can help you assess the invoicing processes and data held in FactsERP, identify the gaps, and prepare the ERP side for integration and testing with your chosen ASP. Speak to the FACTS team to start the review.
Frequently asked questions
Who should lead a UAE eInvoicing project?
Give one project lead responsibility for the schedule and issues, supported by an executive sponsor who can make cross-department decisions. Finance, tax, IT and ERP owners should each approve their own work.
Can finance manage eInvoicing without IT or the ERP provider?
Finance should own the business process, but system mapping, integration, acknowledgements and error monitoring usually require IT and ERP involvement.
Does the ASP take responsibility for our ERP data?
The ASP supports its accredited exchange and reporting functions. Your business still needs to prepare accurate source data, appropriate tax treatment, workflows, testing and oversight.
What should we test before go-live?
Test representative sales invoices, credit notes, incoming supplier invoices, acknowledgements, rejections and corrections. Include the transaction types your business actually uses.
