UAE e-invoicing timeline: key dates, ASPs and a readiness checklist

The UAE's e-invoicing system goes live in phases. Per current Ministry of Finance (MoF) guidance, businesses with revenue of AED 50 million or more had to appoint an Accredited Service Provider (ASP) by 30 October 2026 and go live on 1 January 2027. Businesses below AED 50 million must appoint one by 31 March 2027 and go live on 1 July 2027.

Key points

• E-invoicing is set out in Ministerial Decisions No. 243 and No. 244 of 2025.
• A voluntary pilot started on 1 July 2026.
• Revenue of AED 50 million or more: ASP appointment was due by 30 October 2026, go live 1 January 2027.
• Revenue below AED 50 million: appoint an ASP by 31 March 2027, go live 1 July 2027.
• Government entities follow from 1 October 2027.
• These are the dates per current MoF guidance. Check for updates, as dates can move.

The timeline

Phase	Who	Appoint an ASP by	Go live
Pilot	Selected businesses, voluntary	Not applicable	1 July 2026
Phase 1	Revenue of AED 50 million or more	30 October 2026	1 January 2027
Phase 2	Revenue below AED 50 million	31 March 2027	1 July 2027
Government	Government entities	See MoF guidance	1 October 2027

If you are in Phase 1, the appointment deadline is close. If you are in Phase 2, 31 March 2027 is less than six months away at the time of writing (October 2026), and the work below usually takes longer than businesses expect. Check the MoF guidance for which revenue figure decides your phase.

What actually changes

Today, most UAE businesses create an invoice in their accounting software, save it as a PDF and email it. The tax data reaches the Federal Tax Authority (FTA) only later, through the VAT return.

Under e-invoicing:

• Invoices are created as structured data (a machine-readable file), not as PDFs or scans.
• They are sent through the Peppol network, a standard used for e-invoicing in many countries.
• Invoice data is reported to the FTA close to the time of the transaction, not just once a quarter.

The UAE calls this a decentralised continuous transaction and reporting system. It applies to B2B and B2G invoices and to related documents such as credit notes. A short list of transactions is excluded or treated differently, so check whether any of your supplies fall into it.

The 5-corner model

The system is built on five "corners":

1. Corner 1: you, the supplier. Your accounting or ERP system creates the invoice data.
2. Corner 2: your ASP. It checks the invoice against the required format and sends it.
3. Corner 3: your customer's ASP. It receives the invoice.
4. Corner 4: your customer. The invoice arrives in their system.
5. Corner 5: the FTA. The ASPs report the tax data to the FTA's platform.

You never send an invoice directly to your customer's system or to the FTA. Everything passes through accredited providers.

What an Accredited Service Provider is

An ASP is a company that the MoF has accredited to validate, send, receive and report e-invoices on behalf of businesses. Each business must appoint one. Your ASP and your customer's ASP don't need to be the same company, because Peppol connects them.

Questions to ask before you sign with an ASP:

• Are you on the MoF's list of accredited providers? Ask for evidence.
• Do you connect to my accounting software? Zoho Books, Xero, QuickBooks, Odoo, Tally and SAP users will have different options.
• How do you charge? Per invoice, per month, a setup fee, or a mix. Ask what happens if your volume grows.
• Do you handle both sending and receiving? You will receive e-invoices from suppliers too.
• What happens when an invoice is rejected? Ask how errors are shown and how quickly you can fix and resend.
• How long do you store invoices, and can I export them? You need to meet record-keeping rules for at least 7 years.
• What support do you give during go-live?

We are not an ASP. We help you get your data, software and processes ready, and work alongside the ASP you choose. See our e-invoicing readiness service.

Readiness checklist

Work through this list in order. Most of the effort is in the first five items.

1. Confirm your phase. Check your revenue against the AED 50 million line and note both your appointment and go-live dates.
2. Map your invoice flows. List every way you issue invoices: from the accounting system, from a POS, from a separate billing tool, manually. Include credit notes and any self-billing.
3. Clean your customer and supplier data. Every B2B customer needs a correct legal name, address and TRN where they have one. Errors here cause rejected invoices.
4. Clean your product and service data. Item descriptions, units and VAT treatment (standard, zero-rated, exempt) must be consistent.
5. Check your accounting software. Can it produce structured invoice data or connect to an ASP? If you still invoice from Word or Excel, plan a move now. Our accounting software and ERP service covers setup and migration.
6. Shortlist and appoint an ASP using the questions above.
7. Update your processes. Who raises invoices, who approves credit notes, and what happens if an invoice is rejected?
8. Prepare to receive e-invoices. Your accounts payable team will start receiving structured invoices from suppliers.
9. Test before go-live. Send test invoices, including credit notes and unusual cases.
10. Train the team and set a cut-over date.

Common readiness problems

These are the issues that tend to slow businesses down:

• Invoices raised outside the main system. Sales teams sometimes issue invoices from templates or a separate tool. Every invoice in scope has to pass through your ASP, so these flows need to move into one system.
• Incomplete customer records. Missing TRNs, trading names in place of legal names, and old addresses all cause rejections.
• Inconsistent VAT treatment. The same product coded as standard-rated on one invoice and zero-rated on another will be visible to the FTA.
• Old accounting software. Desktop or heavily customised systems may not connect to an ASP without an upgrade.
• No owner for the project. E-invoicing touches finance, sales, IT and suppliers. Give one person responsibility for the plan and the dates.

Budgeting for e-invoicing

Plan for three types of cost: the ASP's fees (setup and per-invoice or subscription), any software upgrade or migration, and internal time for data clean-up and testing. Ask for written pricing from at least two ASPs, and check whether your accounting software vendor charges extra for the connection.

How e-invoicing links to VAT

E-invoicing does not change VAT rates or registration thresholds. It changes how invoice data reaches the FTA. Because the FTA will see invoices close to real time, mismatches between your invoices and your VAT returns will be easier to spot. Clean VAT records matter more than before. Our VAT services cover registration and quarterly returns.
