If your UAE business has revenue below AED 50 million, you are in the second phase of e-invoicing: appoint an Accredited Service Provider (ASP) by 31 March 2027 and go live by 1 July 2027. This guide turns those two dates into a month-by-month plan and gives you an ERP data checklist. Our UAE e-invoicing integration service does the technical part for you: PINT AE mapping, ASP connection and testing, with no new ERP.
What are the key dates for businesses under AED 50 million?
| Milestone | Date | Source |
|---|---|---|
| Voluntary adoption possible | From 1 July 2026 | MD 244/2025, Art. 4 |
| Appoint an Accredited Service Provider | By 31 March 2027 | MD 244/2025, Art. 5(1)(b) |
| Implement e-invoicing (go live) | By 1 July 2027 | MD 244/2025, Art. 5(1)(b) |
| Intra-VAT-group transactions | Excluded for 24 months from 1 January 2027 | MD 197/2026 |
“Revenue” here means gross income in your most recent accounting period, from your financial statements. The larger businesses (AED 50 million and above) go live earlier, on 1 January 2027, so ASPs and integrators will be busy until then. Starting early helps you avoid the queue.
What does “go live” actually require?
Going live means every in-scope invoice and credit note is issued as a PINT AE e-invoice through your ASP. Under Ministerial Decision No. 243 of 2025 you must:
- Issue and transmit e-invoices for business transactions: within the VAT Law timeline if you are VAT-registered, otherwise within 14 days of the transaction date.
- Issue electronic credit notes when a sale is cancelled, the price is reduced, consideration is returned, or there is an error.
- Receive and process e-invoices from your suppliers through the system.
- Keep your ASP informed of changes to your FTA-registered data within five business days.
What this means for your systems, and who does each part, is explained in ASP vs integrator vs ERP vendor.
What is the month-by-month plan to 31 March 2027?
This plan works back from the two deadlines. It assumes one legal entity and one main invoicing system; add time for each extra system or entity.
| Month | Focus | What to finish |
|---|---|---|
| November 2026 | Scope and inventory | Confirm your Revenue and phase. List every system that issues invoices (ERP, POS, branch tools, spreadsheets). Collect samples of every invoice type you issue. |
| December 2026 | Data clean-up | Fill in customer TRNs and addresses, standardise item and tax codes, and agree how each tax code maps to PINT AE tax categories. |
| January 2027 | Choose your ASP | Shortlist providers from the Ministry’s list, request sandbox access and compare APIs, ERP support, pricing and support hours. |
| February 2027 | Field gap analysis and build | Map every PINT AE mandatory field to your ERP data. Build or configure the connector between your ERP and the ASP. |
| March 2027 | Appoint ASP and test | Sign with your ASP by 31 March 2027. Test standard, zero-rated and exempt invoices, credit notes and rejections in the sandbox. |
| April 2027 | Production onboarding | Complete the ASP’s onboarding, set up Peppol participant identifiers and run real invoices in parallel with your current process. |
| May 2027 | Train and harden | Train billing and finance teams, set up the rejection queue and monitoring, and fix issues from the parallel run. |
| June 2027 | Go-live readiness | Final checks and a cut-over date. Optionally go live early in June to leave a buffer before 1 July 2027. |
If your data is already clean and you use a mainstream ERP, December and January can overlap. If you run custom or multiple systems, start the build earlier.
Which ERP data must be ready?
Most delays come from data, not software. Use this checklist before you build anything.
- Customer TRNs for every business customer, validated and stored in the ERP.
- Customer legal names and addresses in structured fields, not one free-text block.
- Peppol participant identifiers for customers, or a way to look them up with your ASP.
- Tax codes mapped one-to-one to PINT AE tax categories: standard-rated, zero-rated, exempt, reverse charge and out of scope.
- Item data with consistent descriptions, units of measure and codes.
- Invoice numbering that is unique and sequential per entity.
- Credit note references that always point to the original invoice.
- Your own company data (TRN, legal name, address) matching your FTA registration exactly.
- Supplier records ready to receive inbound e-invoices into accounts payable.
Who in your team needs to be involved?
E-invoicing touches more than the accounts team. For a small business, these roles are often held by two or three people, but each one needs a named owner:
| Role | Responsibility |
|---|---|
| Finance owner | Decides tax-code mapping, approves test results, owns rejected invoices after go-live |
| Sales or billing lead | Makes sure customer TRNs and addresses are captured when new customers are created |
| IT or ERP administrator | Gives access to the ERP, adds missing fields, supports testing |
| Purchasing or accounts payable | Prepares to receive supplier e-invoices through the system |
| Management | Signs the ASP contract and the integration scope, and keeps the dates on track |
The most common reason for slippage in small businesses is that data clean-up has no owner. Give it one in November.
What does the go-live week look like?
A calm go-live follows a simple routine:
- Freeze master data changes for the cut-over day, except corrections.
- Switch the connector to production for one entity or branch first.
- Issue a small batch of real invoices and confirm each reaches the ASP and is accepted.
- Check the rejection queue twice a day for the first two weeks.
- Switch on the remaining entities or branches once the first one is stable.
- Review the month-end close with your finance owner, including credit notes.
How do I choose an ASP on a small-business budget?
Look beyond the headline price. Compare annual cost at your real volumes, including credit notes and received invoices, and check:
- whether the ASP has a working connector for your ERP and version, or accepts a third-party connector;
- whether you can export your data and switch provider without rebuilding the integration;
- support hours and language, especially around month-end.
The ASP’s role, and how to evaluate one, is covered in what is an ASP in the UAE.
Can I keep my current accounting software?
In most cases, yes. Tally, Zoho Books, QuickBooks, Xero, Odoo and custom systems can all be connected. The integration reads posted invoices, converts them to PINT AE, checks them and sends them to your ASP, then writes the status back. Your team keeps invoicing the same way.
What if we are late?
Cabinet Decision No. 106 of 2025 sets a fine of AED 5,000 per month for not appointing an ASP or not implementing the system within the deadline, and AED 100 per e-invoice or credit note not issued on time (capped at AED 5,000 per month for each). The full list is in UAE e-invoicing penalties.
