What UAE e-invoicing asks of your business
From your go-live date, a PDF invoice is no longer enough for business-to-business and business-to-government sales.
Each invoice is sent as an XML file in the PINT AE format, built on UBL 2.1.
The FTA expects 51 mandatory fields, from buyer TRN to the tax breakdown on each line.
Invoices travel through an Accredited Service Provider (ASP), which reports them to the FTA.
When your business needs to be ready

How to choose an e-invoicing provider (ASP)
Every UAE e-invoice travels through an Accredited Service Provider. PENTAXIS gets the invoice right, and your ASP delivers it. Before you sign with an ASP, ask:
- Is it on the Ministry of Finance list of accredited providers?
- Does it accept PINT AE files from any source?
- Is pricing per invoice, by volume or a flat fee?
- What support hours and languages does it offer?
- How long does onboarding take?

PENTAXIS questions and answers
Can't find your answer? Ask our team or message us on WhatsApp.
Do UAE businesses need an ASP for e-invoicing?
Yes. Under the UAE e-invoicing model, every e-invoice is exchanged through an Accredited Service Provider (ASP) approved by the Ministry of Finance. PENTAXIS works with whichever ASP you appoint.
Is PENTAXIS an Accredited Service Provider (ASP)?
No. PENTAXIS prepares, validates and archives your e-invoices. Your chosen ASP transmits them to your customer and the FTA, and PENTAXIS records the response.
Does PENTAXIS work with our current ERP or accounting system?
Yes. PENTAXIS works with any ERP or accounting system, including SAP, Microsoft Dynamics, Oracle NetSuite, Odoo, Tally, Zoho and QuickBooks. It reads the export your system already produces in XML, JSON, CSV, Excel or text-based PDF, by upload, SFTP or API.
When does UAE e-invoicing start for my business?
Businesses with revenue of AED 50 million or more appoint an ASP by 30 October 2026 and go live on 1 January 2027. Businesses below AED 50 million appoint by 31 March 2027 and go live on 1 July 2027. Government entities go live on 1 October 2027.
How long does PENTAXIS take to set up?
About one week for most businesses. Omegamatrix maps a sample export of your real invoices first, so you see the result on your own data before you commit.
How much does PENTAXIS cost?
PENTAXIS is priced by monthly invoice volume. Share roughly how many invoices you issue each month and Omegamatrix sends a quote the same day.
Can an accounting or audit firm manage PENTAXIS for its clients?
Yes. Through the PENTAXIS partner programme, accounting and audit firms manage e-invoicing for all their clients from one console, under their own brand.
How long does PENTAXIS keep e-invoicing records?
PENTAXIS keeps sealed records for five years, or seven years for real estate, counted from the correct date. Legal holds pause the clock, and nothing is deleted without an administrator's approval.
Which countries does PENTAXIS cover?
PENTAXIS is built for UAE e-invoicing (PINT AE). For Saudi Arabia (ZATCA) and India (GST e-invoice), NeatAccounts includes e-invoicing.
