E-Invoice in UAE: Step‑by‑Step Guide to FTA eInvoicing and UAE E‑Invoicing Accreditation

The UAE Federal Tax Authority (FTA) is making e‑invoicing mandatory for most business transactions. This means invoices no longer stay as paper, PDF, or free‑text files. They must be issued and exchanged in a structured digital format that the FTA recognises and accepts through a regulated network. The system covers business‑to‑business (B2B) and business‑to‑government (B2G) transactions. Businesses that serve only consumers must still join the process so they can receive structured invoices from their suppliers. UAE e‑invoicing aligns invoice issuance, Peppol network exchange, and tax reporting directly with the FTA’s requirements.

Structured e‑invoice creation and submission replace traditional billing methods. Requirements include strict data fields, controlled transmission paths, and an accredited network element. Missed compliance can lead to rejected invoices, reporting gaps, and penalties. 

The following guide maps out the key steps for FTA eInvoicing, how the UAE’s accreditation system fits into this, and how Flick Network supports businesses through structured invoice creation, validation, Peppol network submission, and real‑time compliance monitoring. 

UAE e‑Invoicing Requirements

UAE e‑invoicing requires each invoice to be a machine readable structured record that conforms to the PINT‑AE format approved by the Federal Tax Authority. This format specifies the exact fields and data types that must appear in every invoice for it to qualify as a valid electronic tax invoice. Traditional formats such as manual billing, PDFs, or scans are not permitted under the rules.

Invoices flow through a controlled exchange model known as the five‑corner model, connecting issuer, buyer, accredited service providers, and the FTA through the Peppol network. This setup enables secure exchange of the invoice and the associated tax data for compliance reporting.

Who Must Comply With UAE e‑Invoicing Rules

All businesses issuing invoices for B2B or B2G transactions in the UAE fall under the e‑invoicing compliance requirement. Non‑VAT registered entities engaged in such transactions are also within scope. Although e‑invoicing is not required for B2C transactions, businesses dealing purely with end consumers must still onboard the system to receive purchase invoices digitally through the Peppol network, which supports accurate record keeping and compliance with FTA reporting expectations

The mandate rolls out in phases, with larger businesses needing to connect to an accredited service provider earlier and smaller companies following later. Integration must occur through FTA‑approved service providers capable of handling structured exchange and reporting obligations.

UAE e‑Invoicing Accreditation Overview

Accreditation is formal approval granted by the UAE Ministry of Finance that allows a service provider to operate within the regulated e‑invoicing system. Only accredited providers can validate, transmit, and report structured invoices and related tax data to the Federal Tax Authority under the e‑invoicing rules.

To achieve accreditation - a provider must meet company and technical criteria such as legal establishment, relevant certifications, Peppol Access Point status, and compliance with interoperability and security standards defined by the Ministry. Accredited providers undergo thorough operational readiness testing before approval and publication on the official list.

Accredited providers must also demonstrate secure data handling, tax data transmission capability, and ongoing compliance with monitoring requirements set by the Ministry.

Step‑By‑Step Guide to FTA eInvoicing

1. Structured Invoice Generation
 Your invoice is created using your billing or ERP system in the PINT‑AE structured format required by the FTA. This includes defined fields for supplier and customer details, VAT values, product codes, and other required data.

2. Transmit to an Accredited Service Provider
 Send the structured invoice to your chosen accredited service provider, such as Flick Network. The provider will validate the invoice against the PINT‑AE specification and verify that all mandatory data has been included.

3. Peppol Network Validation and Exchange
 The accredited provider routes the validated invoice through the Peppol network in compliance with the e‑invoicing exchange model. Delivery status messages signal invoice acceptance or highlight errors that need correction.

4. Tax Data Document Submission
 Alongside the invoice exchange, the service provider generates a Tax Data Document (TDD), which contains all tax‑relevant elements extracted from the invoice. The TDD is submitted to the FTA for real‑time reporting.

5. Status Feedback and Record Retention
 Once the FTA processes the tax data, status responses are relayed back through the service provider to you. These status messages provide confirmation of receipt, acceptance, or any issues. All structured invoices and tax data records must be archived according to UAE retention rules.

6. Exception Handling and Corrections
 If errors appear during validation or submission, corrective actions are taken through the accredited service provider. Credit notes or amended invoices are issued and re‑submitted through the system.

Why Accredited Providers Are Required

Accredited Service Providers, such as Flick Network, are the middle point between your systems and the FTA. They ensure structured invoices conform to mandated standards and that invoice and tax data flow securely through the Peppol network and into the FTA’s systems. ERP and accounting software alone cannot meet these exchange and reporting requirements without integration with approved providers.

Failing to appoint an accredited provider before deadlines can expose businesses to administrative penalties, operational delays, and rejected invoices.
