How the UAE model works
The UAE uses a decentralised "five-corner" model on the Peppol network. A seller's Accredited Service Provider (ASP) validates the e-invoice in the PINT AE format, delivers it to the buyer's ASP, and reports the tax data to the Federal Tax Authority.
Businesses with annual revenue of AED 50 million or more are scheduled to go live on 1 January 2027, after appointing an ASP; other businesses follow in later phases. Always confirm the current timetable with the UAE Ministry of Finance and the FTA.
How UPAX handles it
Each legal entity has its own ASP connection, identified on Peppol by its TRN, and moves from test to the ASP sandbox to production when you are ready. Credentials are write-only: once saved, nobody can read them back.
When the ASP accepts an invoice, UPAX posts the receivable. Delivery to the buyer, FTA reporting and the buyer's response are then tracked through signed callbacks and polling, with undeliverable invoices and buyer rejections flagged for action.
Receiving supplier e-invoices
Incoming PINT AE invoices are read, matched to the supplier by TRN and to the purchase order, and recorded as draft supplier invoices — or parked with a reason. Your team accepts or rejects each one, and the response goes back over Peppol.
