FTA Validates the Invoice in Real Time: The FTA reviews and accepts the invoice instantly. Your transaction is now fully compliant and audit-ready.

Question 14

What are the requirements for e-invoicing in UAE?

Accepted Answer

Key requirements include using the Peppol-based 5-corner model, where invoices must be exchanged through Accredited Service Providers (ASPs) accredited by the Federal Tax Authority (FTA). Invoices must be generated in specific digital formats like XML or JSON using structured standards such as PINT AE (Peppol International Invoice for UAE). Real-time reporting to the FTA is mandatory, and invoices must include mandatory fields like supplier/buyer Tax Identification Numbers (TRNs), VAT breakdowns, and invoice types as per the UAE Data Dictionary.

Question 15

Who is required to prepare an e-invoice?

Accepted Answer

All businesses registered for VAT in the UAE are required to prepare e-invoices for B2B and B2G transactions. This obligation extends even to micro businesses with an annual turnover below AED 3 million, meaning size does not exempt a company from compliance. Non-resident businesses that supply taxable goods or services in the UAE are also included under the mandate. The only current exception applies to B2C transactions, which remain out of scope for now but may be brought under the e-invoicing framework in the future.

Question 16

What software is used for e-invoicing?

Accepted Answer

Complyance is a global e-invoicing platform that works in 100+ countries through one simple API. It takes care of tax rules, formats, and real-time checks; no changes needed in your ERP, Accounting software, or POS. Our GETS framework turns your invoice into the right format for each country automatically. From Peppol to PINT, Complyance helps you stay compliant without the manual work.

Question 17

How do I generate an e-invoice from my ERP?

Accepted Answer

It typically involves using a dedicated transaction or report to create a standard invoice. However, for compliance, the critical next step is transforming that internal invoice file into the government-mandated format (like XML or JSON in the UAE) and then securely transmitting it to the tax authority's platform. Many ERPs need an added integration solution to handle this compliance step automatically.

Question 18

How is e-invoicing implemented in SAP?

Accepted Answer

You should configure SAP's native output settings for invoices, often using tools like SAP Document Compliance, and most importantly, you should integrate SAP with a certified third-party compliance solution or middleware like Complyance. Their system takes the invoice data from SAP, ensures it meets all local regulatory rules (like the UAE's FTA requirements), converts it into the correct format, and submits it to the government portal. This end-to-end managed process is what ensures your SAP-generated invoices are fully compliant.

Question 19

What is the difference between an API and an ERP?

Accepted Answer

Your ERP is the central software that manages your core processes like finance, sales, and inventory. An API (Application Programming Interface), on the other hand, allows your ERP to communicate seamlessly with other external systems. For e-invoicing compliance, an API is what allows your ERP to safely send invoice data to the government's tax authority system and receive a compliance approval back without any manual work.

Question 20

What if an e-invoice is not generated within 30 days?

Accepted Answer

Failure to issue an e-invoice within the required timeframe, such as 30 days, may result in penalties under UAE VAT laws, including fines starting at AED 5,000 for the first violation, potential audits by the Federal Tax Authority (FTA), and disruptions in B2B/B2G transactions. Specific guidelines will be clarified closer to the July 2026 e-invoicing mandate. Businesses should ensure timely compliance and monitor FTA updates.
