PINT AE format & the 51 mandatory invoice fields
Many websites talk about "the electronic invoice" as if it were just a PDF you email to a client. That is not correct. The UAE's e-invoicing model is built on a structured data format called PINT AE, and an invoice is only compliant when it is issued in that format and exchanged between both parties through an Accredited Service Provider (ASP).
What is PINT AE?
PINT AE is the national billing specification (PINT AE Billing) adopted within the country's technical e-invoicing model. It sits on the Peppol network in a "five-corner" model (DCTCE): the supplier creates the invoice, it travels from the supplier's ASP to the buyer's ASP and then to the buyer, while being reported to the Federal Tax Authority through the FTA e-Billing system. So an invoice is not just a document you look at — it is a machine-readable data message that follows a defined route.
Why a plain PDF is not compliant
A PDF — however neat and tidy it looks — is designed to be read by a human, not a machine. The buyer's system and the FTA cannot reliably extract the fields from it, and it does not travel the five-corner path. Therefore:
- A paper, scanned, or emailed-PDF invoice is not a compliant e-invoice.
- Owning accounting software that prints a PDF does not make you compliant; you must issue in PINT AE format and exchange it through an ASP.
- There is no free government issuance portal like Saudi Arabia's "Fatoora"; in the UAE every invoice must pass through an accredited provider.
The 51 mandatory fields
The PINT AE specification defines a set of 51 mandatory fields that every invoice must carry. Their purpose is to make each invoice complete and standardized so that any system in the country reads it the same way. If a mandatory field is missing, the invoice may not be valid for exchange or reporting. The exact official list of these fields is published on the Ministry of Finance portal; review it with your provider before you go live, and do not rely on unofficial lists.
What data should you prepare?
Practically, start now by cleaning up your core data so it maps easily into PINT AE. This usually includes:
- Accurate identity details for you and for your business and government customers (including tax-registration details where they exist).
- Invoice line items, quantities, prices, and the VAT breakdown.
- An organized register of your B2B and B2G customers — these transactions are the ones in scope today, while consumer (B2C) sales are excluded for now.
An important note: scope has nothing to do with VAT registration. Even a business that is not VAT-registered is in the system if it issues invoices to companies or government entities. Remember, too, that input-VAT recovery now requires keeping the electronic invoice (under Federal Decree-Law 16 of 2024, amending Article 55 of the VAT Law), with records retained inside the UAE for 5 to 7 years.
