UAE eInvoicing roadmap for businesses below AED 50 million: a month-by-month plan to the ASP appointment and go-live dates

Published 23 October 2026 · Official sources last reviewed 22 October 2026 · 11 min read

If your business is a person subject to the UAE eInvoicing system and its Revenue is below AED 50 million, you have two legal milestones: appoint an accredited service provider (ASP) by 31 March 2027, and implement eInvoicing by 1 July 2027. Counted from the publication date of this guide, that is 159 days to the appointment date and 251 days to go-live. This guide turns those two dates into a month-by-month plan, working backwards so that the internal work is finished before the provider is appointed and the testing is finished before go-live.

The roadmap is an editorial planning aid, not an official schedule from the Ministry of Finance (MoF) or the Federal Tax Authority (FTA). The only fixed dates in it are the two set by law. Everything between them is a suggested order of work that you should adapt to your own systems, volumes and advisers. We do not name or compare providers, and we do not estimate costs.

Your two dates and the shape of the plan

The dates come from Article 5(1)(b) of Ministerial Decision 244/2025. Ministerial Decision 66/2026 replaced only Article 5(1)(a), which covers the larger category, so the dates for the category below AED 50 million are those in the original Article 5(1)(b).

Legal milestones for the category below AED 50 million (Decision 244/2025, Article 5(1)(b))
Milestone	Date	Days from 23 October 2026
ASP appointment	31 March 2027	159
eInvoicing implementation	1 July 2027	251

The window between appointment and go-live is 92 days. That is the time available for onboarding, data mapping against your provider requirements and end-to-end testing. It is short, so the plan below puts the inventory, data and scope work before the appointment date rather than after it. The roadmap has three phases:

November and December 2026: confirm your category and scope, name an owner, and build your data and system inventory.
January to March 2027: brief, compare and appoint an accredited ASP by 31 March 2027.
April to June 2027: map data, document exception flows, run scenario tests and prepare the go-live decision before 1 July 2027.

The key dates summary on our home page and our guide to the UAE eInvoicing deadlines show all three official timetables side by side.

Step one: confirm you really are in the below AED 50 million category

The category is decided by Revenue, and Revenue has a legal definition. Article 1 of Decision 244/2025 defines Revenue as gross income during the most recent Accounting Period, based on the financial statements you are required to prepare or other documentation acceptable to the FTA. Article 1 also defines Accounting Period; read that definition in the official text rather than relying on a summary.

The boundary matters. Decision 66/2026 rewrote Article 5(1)(a) so that the larger category covers persons subject to the system with Revenue equal to or exceeding AED 50,000,000. A business with Revenue of exactly AED 50,000,000 is therefore in the larger category, not in this one, and its appointment date of 30 October 2026 is much closer. Some announcements describe the larger group in looser words; the binding decision text governs.

What to record now

Which financial statements, for which Accounting Period, you used to measure Revenue.
The Revenue figure and who in finance confirmed it.
Any reason the figure might be close to the boundary or might be measured differently, and whether a tax adviser has reviewed it.

Our guide to the AED 50 million revenue threshold walks through the definition, the inclusive boundary and the questions the texts do not answer. The glossary explains Revenue, Accounting Period and the other defined terms.

Step two: confirm that you are subject to the system at all

A revenue figure only tells you which timetable applies if you are a person subject to the system. It does not decide that you are. Scope is set by Ministerial Decision 243/2025, whose Article 4 exclusions were replaced by Ministerial Decision 197/2026 with effect from 1 October 2026. Check three things before you build a project around the dates.

Transaction scope and exclusions. Decision 243/2025 applies to Business Transactions unless they are excluded. Our transaction scope guide and the guide to sector exclusions for airlines, financial services and Government Entity transactions go through the list.
The B2C exclusion. Article 5(2) of Decision 244/2025 excludes B2C transactions and persons engaged exclusively in them until a further ministerial decision. A business that also sells to other businesses or to government needs a separate check. See the B2C exclusion guide.
The Tax Group exclusion. Ministerial Decision 197/2026, which amended Decision 243/2025 with effect from 1 October 2026, treats Business Transactions between members of the same VAT Tax Group as Excluded Transactions for 24 months starting 1 January 2027 (amended Article 4(1)(f)). Check the full list of exclusions in the official text. It removes transactions between group members, not your sales to outside customers, and it is temporary. Our guide to Decision 197/2026 explains the change.

If you are a Government Entity, you are not in a revenue category at all; see the Government Entity timeline. If you are still unsure, run the free eInvoicing readiness check and take the result to your tax adviser.

November and December 2026: owner, data and system inventory

This phase is about knowing what you have. None of it depends on which provider you choose, and all of it makes the provider discussion faster.

November 2026

Name one project owner with authority across finance, IT and the business units that issue invoices, and agree how decisions are recorded.
Document the category and scope conclusions from steps one and two, including any open questions for your adviser.
List every place an invoice or credit note can be created: the main accounting or ERP system, billing tools, spreadsheets, branches and agents.

December 2026

Extract customer and supplier master data from each system, and record duplicates, missing values and conflicting records.
Flag counterparties whose status matters for scope, such as Government Entities, members of your VAT Tax Group and consumers.
Record where invoice details live as structured data and where they exist only in PDFs, free text or attachments.
Ask each software vendor what integration options it offers, and write down the answers.

Our readiness project plan sets out these tasks as eight workstreams with practical detail.

January to March 2027: choose and appoint an accredited ASP

The appointment date of 31 March 2027 is a legal deadline, so treat the first quarter of 2027 as the provider quarter. The rules on who may act as a provider changed recently. Ministerial Decision 168/2026, in force from 1 October 2026, replaced the earlier service-provider rules (Decision 64/2025 and its amendments, including Decision 56/2026). It removed the former pre-approval stage and introduced direct accreditation, so an earlier pre-approval label is not the same as accreditation under the current framework. Reconfirm a provider's current accreditation status through official channels before you appoint it.

In practice this means that a provider described as “pre-approved” in older material is not, on that basis alone, accredited under the current framework. Check current accreditation through official channels close to the time you sign, using the MoF announcement on Decision 168/2026 and the MoF eInvoicing programme page as starting points.

January 2027: turn your inventory into a short brief: invoice routes, volumes by route, systems, credit note flows and known data gaps. Agree internal selection criteria before you speak to providers.
February 2027: compare providers against the brief, confirm each one is accredited under the current framework, and settle contract and onboarding terms with your own legal and procurement review.
March 2027: complete the appointment by 31 March 2027, keep a record of the accreditation check, and agree an onboarding and testing timetable that ends before 1 July 2027.

Our guide to choosing and appointing an ASP under Decision 168/2026 covers the accreditation change and a selection checklist in more detail.

April to June 2027: exception flows, scenario tests and go-live preparation

After appointment, the work moves from inventory to proof. Ordinary invoices are rarely the problem; corrections and exceptions are. Article 6 of Decision 243/2025 sets out what Issuers and Recipients must do, including the cases in which a credit note is required: cancellation, a reduction of the consideration, a return of consideration, and administrative or numerical errors.

Timing is part of the rule. For Issuers that are VAT Registrants, Article 6(4) points to the VAT Law timeline. Article 6(5), as replaced by Decision 197/2026, sets a period of fourteen Business Days from the Date of Business Transaction, subject to Article 6(4). Our guide to Issuer and Recipient obligations under Article 6 explains how these provisions fit together.

April 2027: map your invoice data against the requirements your provider and the current official specifications set, and document each credit note and correction flow with an owner.
May 2027: run scenario tests: normal invoices, counterparty data errors, rejection and resubmission, each credit note case and recovery after an outage. Record expected and actual results.
June 2027: close or accept the remaining defects with named owners, train the staff who issue and process invoices, tell key customers and suppliers what will change, and make a documented go-live decision before 1 July 2027.

The go-live testing checklist gives a fuller list of scenarios and the evidence worth keeping.

How this timetable differs from the other two categories

The same law sets three timetables. Comparing them helps explain why this roadmap looks the way it does.

All three timetables (Decision 244/2025, Article 5(1), with Article 5(1)(a) as replaced by Decision 66/2026)
Category	Appoint an ASP by	Implement by	Basis
Annual revenue AED 50 million or more	30 October 2026	1 January 2027	Including exactly AED 50,000,000. Decision 244/2025, Article 5(1)(a), as amended by Decision 66/2026.
Annual revenue below AED 50 million	31 March 2027	1 July 2027	Decision 244/2025, Article 5(1)(b).
Government entities	31 March 2027	1 October 2027	Decision 244/2025, Article 5(1)(c), which applies to Government Entities.

The larger category must appoint by 30 October 2026 and implement by 1 January 2027. Its window is shorter and its dates come first, so a business close to the boundary should settle its category before anything else. Our week-by-week roadmap for businesses with Revenue of AED 50 million and above covers that timetable.
Government Entities share your appointment date of 31 March 2027 but implement later, by 1 October 2027, giving them a longer testing window. They are not sorted by revenue.
Your category shares the appointment date with Government Entities but implements on 1 July 2027, so you have less time after appointment than they do.

What this roadmap cannot confirm

Several questions that matter for planning are not answered in the official texts we have reviewed, or are outside what this site has recorded. We do not guess at them. Check the current official texts and ask a qualified UAE tax adviser.

Revenue changes during or between Accounting Periods. We have not identified a rule on whether, or when, a business moves between categories if its Revenue changes.
Group aggregation. Whether Revenue is measured for a single entity or combined across related entities is not settled in the material we have reviewed.
Technical field specifications. Field-level data requirements are not covered here. Confirm them against current official material and with your provider.
How penalties are applied. The penalty amounts are set in Cabinet Decision 106/2025 and apply to all categories: AED 5,000 for each month or part of a month of delay in implementing the system, including late ASP appointment, and AED 100 per late Electronic Invoice or Electronic Credit Note, up to AED 5,000 per calendar month. Voluntary participants are excluded. We have not confirmed its exact entry-into-force date (the Official Gazette publication date) or how the FTA applies it in practice; see our Cabinet Decision 106/2025 penalties guide.
Costs. Costs depend on your systems, volumes and provider. We do not publish estimates.

Official updates are published by the MoF on its eInvoicing programme page and by the FTA, which has, for example, announced a joint awareness meeting for accredited service providers and persons subject to the eInvoicing system. Our legislation map shows which decision answers which question.

Frequently asked questions

Is this the official schedule for smaller businesses?

No. Only the two dates, 31 March 2027 and 1 July 2027, are set by law. The monthly phases are an editorial suggestion.

Our Revenue is exactly AED 50 million. Does this roadmap apply?

No. Under Article 5(1)(a) as replaced by Decision 66/2026, Revenue equal to or exceeding AED 50,000,000 falls in the larger category, with an appointment date of 30 October 2026 and implementation by 1 January 2027.

Can we appoint a provider before 31 March 2027?

The law sets the date by which you must appoint, so appointing earlier is consistent with it. An earlier appointment also gives you more time for testing. Confirm the provider is accredited under the current framework when you appoint.

We only sell to consumers. Do we need this plan?

Persons engaged exclusively in B2C transactions are excluded under Article 5(2) of Decision 244/2025 until a further ministerial decision. Mixed businesses need a separate check. Because the exclusion is temporary, keeping a light inventory is sensible.

Does the Tax Group exclusion change our dates?

No. Decision 197/2026 did not amend the Decision 244/2025 timetable. The exclusion removes transactions between members of the same VAT Tax Group for a limited period; sales outside the group follow the normal rules.
