Rule one: one law, not seven versions
Whichever emirate you're in, your deadlines are the same: a voluntary pilot from 1 July 2026, mandatory for large businesses (revenue ≥ AED 50 million) from 1 January 2027, and mandatory for everyone else from 1 July 2027. Scope is the same everywhere too: B2B and B2G transactions only, B2C currently excluded. Full details in our deadlines article.
What actually differs between emirates: context, not law
What genuinely differs between emirates is: concentration of free zones (Dubai and Abu Dhabi have the most), the nature of the local economy (industrial in Sharjah and Ras Al Khaimah, logistics-heavy in Fujairah, government-heavy in Abu Dhabi), and where ASP providers publicly state their headquarters (mostly Dubai, per our research). This context matters because it shapes your priorities — a manufacturing business in Sharjah benefits more from the Incoming Invoice Centre (PO matching), while a logistics company in Fujairah needs more focus on high-volume, cross-border invoicing.
