The two deadlines you must not confuse
Every business faces two separate deadlines, with a gap of two to three months between them:
- The provider appointment deadline. This one comes first, and exceeding it triggers a recurring monthly penalty. Many businesses overlook it entirely because they are focused on the second one.
- The go-live deadline. The day every in-scope invoice you issue must be produced electronically through the system.
The gap between them is deliberate: it is the window allocated for implementation, integration and testing. A business that appoints its provider on the last possible day enters go-live with no time left to test — reason enough on its own to contract early.
The official timetable
| Category | Appoint a provider by | Compliance starts |
|---|---|---|
| Phase 1 Annual revenue ≥ AED 50 million | 30 October 2026 | 1 January 2027 |
| Phase 2 Annual revenue < AED 50 million | 31 March 2027 | 1 July 2027 |
| Government entities | — | 1 October 2027 |
These phases were preceded by a voluntary pilot that opened in July 2026 — a useful opportunity for anyone who wanted to test early without commitment.
Why did the first deadline move? And will it move again?
The Phase 1 appointment deadline was originally 31 July 2026, then officially extended to 30 October 2026. The stated reason was to give the market more time following feedback about the limited options available at that point.
Will it be extended again? Nobody can say for certain, but two observations are worth weighing:
- The extension covered the appointment deadline only, while the 1 January 2027 go-live date stayed fixed. That suggests regulators are holding firm on the go-live.
- The number of accredited providers has grown to 44, meaning the original reason for the extension — too few options — no longer applies to the same degree.
Building your plan on the assumption of another extension is a risky bet: if it does not come, the penalty has already been accumulating monthly while you were still shopping for a provider.
How to determine your own deadline
The criterion is annual revenue — not headcount, not capital, not invoice volume. Three practical cases:
Your revenue is clearly above AED 50 million
You are in Phase 1. Check the table above and start today if you have not already — you have less time remaining than you think.
Your revenue is clearly below AED 50 million
You are in Phase 2. You have more room, but don't relax: the number of businesses in this bracket is enormous, and demand for providers will peak in early 2027. Contracting in the final quarter of your window means paying more and getting slower service.
Your revenue sits near the threshold, or fluctuates
This is the trickiest and most dangerous case. If your revenue swings around AED 50 million from year to year, the prudent move is to assume you are in Phase 1 and prepare accordingly. The cost of preparing early is far lower than the cost of discovering late that you were in scope months ago. Review how revenue is calculated with your accountant to confirm your position.

Find your deadline in two minutesWorking backwards: when to start each step
Count backwards from your go-live date:
| Time before go-live | What should be done |
|---|---|
| 6 months | Confirm your phase, assess your accounting system, begin cleaning customer data |
| 4 months | Compare at least three providers and request written quotes |
| 3 months | Sign with your provider (roughly the official appointment deadline) |
| 2 months | Technical integration with your accounting system |
| 1 month | Testing in the sandbox with real invoices |
| 2 weeks | Train the finance team and work through test rejections |
If you look at this table and find you are behind on a milestone, that is not a disaster — but it is a signal to compress the schedule and start the next step now rather than waiting.
