The UAE's Electronic Invoicing System, established by Ministerial Decision No. 243 of 2025, replaces PDF invoices with structured e-invoices exchanged over the Peppol network under a 5-corner (DCTCE) model and reported to the Federal Tax Authority. Businesses with revenue of AED 50 million or more must appoint an Accredited Service Provider by 30 October 2026 and go live by 1 January 2027; smaller businesses follow by 1 July 2027 and government entities by 1 October 2027. Invoices follow the PINT AE specification with 51 mandatory fields, penalties under Cabinet Decision No. 106 of 2025 start at AED 5,000 per month, and RESON, an Odoo Partner in Dubai, helps UAE businesses prepare their ERP and master data for compliance.
