For most businesses, understanding e-invoicing itself is not the hard part. The hard part is picking the right ASP. Once you appoint one, every e-invoice your business sends or receives runs through them, so this is not a decision to rush. This guide walks through what actually matters when you compare providers, so you pick one that works well from day one.
What Counts as a UAE E-Invoice?
A UAE e-invoice is structured data about a sale, not a PDF, a scanned copy, or a photo of a paper invoice. Once the mandate applies to your business, only invoices sent this way, through an ASP, count. A PDF emailed to your customer will no longer be valid.
What Is an ASP, in One Line?
An ASP, or Accredited Service Provider, is a company approved by the UAE Ministry of Finance to check your e-invoices and send them over the Peppol network to your buyer and to the Federal Tax Authority. You cannot send a UAE e-invoice without one.
Eight Things to Check Before You Appoint an ASP
1. Is the Provider Actually Accredited, or Only Pre-Approved?
The Ministry of Finance uses two stages. A pre-approved provider has passed the first checks. An accredited provider has completed the full process under Article 16 of Ministerial Decision No. 64 of 2025 and can handle live invoices. As of 28 September 2026, the Ministry's own list shows 60 fully accredited providers and 3 more still under final assessment. Before you sign anything, check the provider's name and accreditation number directly on the Ministry of Finance's list, not on the provider's own marketing page. Accreditation is also reported to run for two years and need renewal, and since May 2026, a local provider is allowed to partner with an international one for technology, so it is fair to ask a shortlisted provider both how they are structured and when their accreditation is next due for renewal.
2. How Long Have They Actually Run E-Invoicing?
Ask two separate questions here, not one. How long has the provider run e-invoicing services generally? And separately, how long have they been a Peppol Service Provider? A company can be new to Peppol even if it has done other kinds of invoicing for years, and a provider that has handled real invoices, credit notes and error cases for longer is less likely to be caught out by something you run into.
3. Do They Have Real Support in the UAE?
Ask which Emirate they operate from and how you reach support when something goes wrong. A provider with a local office and local working hours can help faster than one running support from a different time zone.
4. Does It Work With the Software You Already Use?
If your ASP is a separate system from your accounting software, you type or import your invoices twice. Ask whether the provider connects directly to your existing accounting software, and whether that software already supports the required Peppol BIS 3.0 or UBL 2.1 format, or whether you need new integration work first.
5. How Is Your Data Handled?
Your ASP sees your sales, your buyers, and your VAT details. Ask where your data is stored and how it is protected before you appoint anyone.
6. What Does It Cost, Broken Down?
Ask for the full cost picture, not just one number. This usually means five separate things: the setup cost, the monthly or yearly subscription, the price per invoice once you go over any free allowance, any customisation charges, and ongoing support costs. Several sources tied to Ministerial Decision No. 64 of 2025 say ASPs must offer a set number of free e-invoices each year to small businesses, often cited as 100. Ask your provider directly whether this applies to you, and get all five costs in writing before you sign.
7. Can It Grow With Your Business?
A provider that works fine today at your current invoice volume may struggle if you open a second branch, add more staff, or your invoice count grows. Ask what happens to your pricing and your support if your volume doubles, and whether the provider has UAE customers of a similar size to where you expect to be in two years.
8. Can One ASP Handle Both Your Sales and Purchase Invoices?
You appoint one ASP for your business, not one for sales and another for purchases. Splitting this creates two systems to manage and two places for errors to hide.
Common Mistakes Businesses Make When Choosing an ASP
- Picking the cheapest provider without checking it connects to the software you already use
- Counting only your taxable sales toward the AED 50 million line, instead of your full gross income
- Assuming your business is automatically out of scope because it is not VAT registered
- Leaving customer and supplier records messy until testing has already started
- Letting one person handle the whole decision, without input from finance, tax and IT
What to Prepare Before You Start Onboarding Your ASP
Once you have shortlisted a provider, most ASPs will ask for a few things before onboarding starts:
- Your accounting or invoicing software's name and version, and whether it supports the required Peppol format
- A named technical contact for the integration
- Your company registration documents, if a partner is handling onboarding on your behalf
- A letter of authorisation, if someone else is onboarding for you
While comparing providers, it also helps to ask directly:
- Whether their integration method, a direct API, a Peppol access point, or middleware, fits your system
- Their Service Level Agreement, including uptime and what happens if a transmission fails
- Whether they give you a proper testing environment before go-live
- Their onboarding timeline, and whether support is available in your preferred language
The most common ASP onboarding mistakes are invoice fields that are not mapped correctly to the required format. This causes repeated test failures, missing authorisation paperwork when someone else is onboarding for you, and asking to go live before finishing the required test sign-off.
How to Appoint and Register Your ASP for UAE E-Invoicing on EmaraTax
Once you have picked a provider, appointing an ASP happens on the EmaraTax portal. In short, you open EmaraTax, select your VAT-registered entity, choose your ASP from the approved list, and submit the request. If you are appointing Tally, our full step-by-step guide shows every screen, from TallyPrime to EmaraTax and back.
ASP Registration Deadline in the UAE
| Business Size | Appoint an ASP By | E-Invoicing Becomes Mandatory |
|---|---|---|
| Annual revenue AED 50 million or more | 30 October 2026 | 1 January 2027 |
| Annual revenue below AED 50 million | 31 March 2027 | 1 July 2027 |
| Government entities | 31 March 2027 | 1 October 2027 |
The Ministry of Finance moved the first deadline from 31 July 2026 to 30 October 2026. The go-live dates did not change.
What to Keep Ready After You Appoint Your ASP
Going live is not the end of the work. It is worth being able to show, at any time:
- Your signed agreement with your ASP, including how your data is hosted and protected
- Updated customer and supplier records, with the right tax numbers on file where they apply
- A record of your testing, covering normal sales as well as other cases like exports or credit notes
- Sign-off from your finance, tax and IT people that each step is genuinely done
- A plan for what happens if the system goes down, agreed with your ASP in advance

Frequently Asked Questions
1What is an ASP for UAE e-invoicing?
An Accredited Service Provider (ASP) is a company approved by the UAE Ministry of Finance to validate your e-invoices and send them over the Peppol network to your buyer and to the Federal Tax Authority. Businesses in scope must appoint one before they can send e-invoices.
2Is e-invoicing mandatory in the UAE?
Yes. It becomes mandatory on 1 January 2027 for businesses with annual revenue of AED 50 million or more, and from 1 July 2027 for businesses below that. The dates are set under Ministerial Decisions 243 and 244 of 2025.
3What is the difference between an ASP and Peppol?
Peppol is the network itself, the set of rules that lets invoices move securely between different systems. An ASP is the company you appoint that connects your business to that network, checks your invoices against the rules, and handles delivery. You need an ASP to use Peppol; Peppol is not a company you sign up with directly.
4How does an e-invoice actually travel between two businesses?
Your business sends invoice data to your ASP. Your ASP checks it, turns it into the required PINT AE format, and sends it to your buyer's ASP, while also reporting your tax data to the Federal Tax Authority. Your buyer's ASP checks what it receives and passes the invoice to your buyer, then reports its own tax data separately.
5Do I need an ASP even if I am not VAT registered?
E-invoicing in the UAE applies more broadly than VAT registration alone. If your business carries out business transactions in the UAE, you may be in scope even without VAT registration, unless a specific exclusion applies to you. Check your situation with your tax advisor or the Ministry of Finance.
6Can I use one ASP for both my sales and purchase invoices?
Yes. You appoint one ASP to handle both the e-invoices you send and the ones you receive.
7How do I register my ASP on EmaraTax?
You open the EmaraTax portal, log in, select your VAT-registered entity, choose your ASP from the approved list, and submit the request. If you are appointing Tally from TallyPrime, our step-by-step ASP guide covers every screen.
8When is the ASP registration deadline in the UAE?
Businesses with annual revenue of AED 50 million or more must appoint an ASP by 30 October 2026. Businesses below that must appoint one by 31 March 2027, and so must government entities.
9Is Tally an accredited ASP in the UAE?
Yes. Tally Software Solutions FZCO is on the Ministry of Finance's list of Accredited Service Providers, with Accreditation Number 162503.
10What happens if I appoint the wrong ASP, or none at all?
Without an appointed ASP, your business cannot legally send e-invoices once the mandate applies to you. Switching providers later is possible, but it means redoing data migration, testing, and training, so it is worth choosing carefully the first time.
