UAE eInvoicing for accounts receivable: how an Issuer issues and transmits Electronic Invoices and Credit Notes under Articles 6, 8 and 9

Published · Decisions 243/2025 and 197/2026 read in the official English text on 23 October 2026 · Other official sources last reviewed 22 October 2026 · 11 min read

For a business that sells, UAE eInvoicing lands first on the billing desk. The accounts receivable (AR) team, together with sales operations and whoever runs the invoicing system, has to turn every in-scope sale into a structured Electronic Invoice, send it through the system on time and correct it with an Electronic Credit Note when something changes. The practical questions are simple to ask and harder to answer. Which sales need an Electronic Invoice? Which clock applies to us? When must we raise a credit note? Who else may issue on our behalf, and which customers are outside the system?

This guide answers those questions from the seller’s side, using the text of Ministerial Decision No. 243 of 2025 on the Electronic Invoicing System as amended by Ministerial Decision No. 197 of 2026, and the timetable in Ministerial Decision No. 244 of 2025. It keeps what the text says apart from our own reading and lists what we have not been able to confirm. It is the companion to our accounts payable and Recipient guide, which covers the buyer’s side of the same articles, and it builds on our overview of Issuer and Recipient obligations under Article 6. For the separate process of matching customer bank receipts to invoices, see our AR cash application and unidentified receipts guide.

Who counts as the Issuer

Article 1 of Decision 243/2025 defines the Issuer as the Person obligated to issue, transmit, share and exchange Electronic Invoices and Electronic Credit Notes through the Electronic Invoicing System. The Recipient is the Person who receives them. In an ordinary sale, your business is the Issuer and your customer is the Recipient. Most businesses are both: an Issuer in the AR ledger and a Recipient in the AP ledger. That is why we suggest the two teams share one readiness plan, one ASP relationship and one set of counterparty records rather than preparing separately.

A structured document, not a PDF

Electronic Invoices and Electronic Credit Notes are defined as documents issued, transmitted and received in a structured electronic format that enables automatic and electronic processing. An invoice designed as a printable layout and emailed as a PDF is not what that definition describes. For the AR team, the invoice becomes data produced by the billing system and passed through the Electronic Invoicing System. Article 7 says the data fields and particulars are those prescribed by the Ministry. We have not reviewed a field-by-field specification, so this guide does not list mandatory fields or describe a file format. The defined terms used here are explained in our glossary.

Article 6(1): an Electronic Invoice for every in-scope Business Transaction

Article 6(1) requires the Issuer to issue and transmit an Electronic Invoice through the Electronic Invoicing System for any Business Transaction, subject to Articles 8, 9 and 10. Article 3(a) brings into scope any Person conducting Business in the State in respect of every Business Transaction, unless the person or the transaction is excluded under Article 4. Read together, the starting point for AR is broad: every sale made in the course of Business is a candidate for an Electronic Invoice until an exclusion is identified.

Articles 8 and 9, explained below, allow someone other than the Issuer to issue in particular cases. This guide does not describe Article 10, so check that article in the official text if your arrangements might fall under it.

Our reading for AR

On our reading, the safest working assumption for an in-scope seller is that each billable sale needs an Electronic Invoice issued through the system, and that any sale treated as outside the system should have a documented reason, such as one of the exclusions discussed below. Our transaction scope guide walks through B2B, B2G, cross-border and VAT registration questions in more detail.

The AR workflow: from order to correction

The rules do not prescribe an internal workflow. The four stages below are our editorial way of mapping the articles onto a typical order-to-cash process, so that each rule has an owner in the AR team.

  1. Order and customer set-up. Before a sale is invoiced, the customer record should show what the rules depend on: whether the customer is a Registrant, a Government Entity, a fellow member of your VAT Tax Group or a consumer, and whether an agent bills for you. Our master data readiness guide covers this clean-up.
  2. Issue. The billing system produces the structured Electronic Invoice for the Business Transaction, using the data model your ASP supports.
  3. Transmit. The invoice is sent through the Electronic Invoicing System via your appointed ASP within the applicable timeline, discussed in the next section.
  4. Correct. When one of the four Article 6(2) events happens, an Electronic Credit Note is issued and transmitted, rather than an informal adjustment.

Reporting to the Federal Tax Authority under Article 6(6) sits alongside these stages. Our dedicated Article 6(6) reporting obligations guide explains the shared Issuer and Recipient reporting wording and how to verify the applicable timeline without guessing. Testing each stage before go-live is covered in our go-live testing checklist.

Timing under Articles 6(4) and 6(5)

Two paragraphs decide how quickly an Issuer must act, and they depend on whether your business is registered for VAT.

Registrants follow the VAT Law timeline

Where the Issuer is a Registrant (a person registered for VAT with a Tax Registration Number), Article 6(4) requires it to issue and transmit the Electronic Invoice and Electronic Credit Note within the timeline prescribed by the VAT Law. Decision 243/2025 does not repeat that timeline, and this guide does not state a number of days for it. Confirm it with your tax adviser and build it into your billing calendar.

Fourteen Business Days from the Date of Business Transaction

Decision 197/2026, in force from 1 October 2026, replaced Article 6(5). The current text requires issue and transmission through the system within fourteen (14) Business Days from the Date of Business Transaction, subject to Article 6(4). The original wording said 14 days. The MoF explained the October amendments in its announcement of 19 October 2026, and our Decision 197/2026 guide covers the other changes.

Our editorial reading is that a Registrant Issuer follows the VAT Law timeline and the fourteen Business Day period applies to Issuers outside Article 6(4). Either way, AR needs two data points per sale. The first is the Date of Business Transaction, which is the earlier of the date the transaction occurred or the date payment was received; an advance payment can therefore start the clock before goods or services are delivered. The second is a count of Business Days, meaning every day except weekends and official Federal Government holidays. The decision does not list those holidays, so use the current federal calendar. If your process invoices only on delivery, check how deposits and prepayments are captured.

Credit notes: the four Article 6(2) cases

Article 6(2) requires the Issuer to issue and transmit an Electronic Credit Note to the Recipient where:

  1. the Business Transaction is cancelled;
  2. the agreed consideration is reduced for any reason;
  3. the consideration is returned in full or in part;
  4. an administrative or numerical error has occurred in relation to the Business Transaction.

What this means for AR

These cases cover the everyday corrections an AR team already handles: cancelled orders, discounts and rebates agreed after invoicing, refunds and wrong amounts or details. The duty sits with the seller, and Article 6(4) names Electronic Credit Notes as well as Electronic Invoices, so credit notes need the same timing discipline as invoices. A practical control is to link each of these events in your billing system to a credit note trigger, so that an informal fix such as a manual write-off, a payment deduction accepted without paperwork or an email to the customer does not replace the credit note the rule describes.

The text we read does not say how a credit note must reference the original invoice, how a price increase is handled or how partial returns are calculated. Agree these with your adviser and your ASP, and test them before go-live. Our Electronic Credit Notes guide covers the four cases, the timing rules and self-billed credit notes in more detail.

Article 6(6) reporting and Article 6(7) ASPs

Article 6(6), which Decision 197/2026 did not replace, says the Issuer and the Recipient report Electronic Invoices and Electronic Credit Notes to the Federal Tax Authority within the timeline prescribed by the Minister. We have not identified that ministerial timeline, so this guide gives no reporting deadline. What the text does make clear is that reporting is an obligation of the seller as well as the buyer.

Article 6(7) says the Issuer and the Recipient fulfil their Article 6 obligations through the appointment of an Accredited Service Provider. For AR, the ASP is the route by which invoices and credit notes leave your billing system and reach the customer through the system. The accreditation rules 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. The MoF described the change in its announcement on Decision 168/2026. In short, a provider described in older material as “pre-approved” should not be treated as currently accredited without checking. Our guide to choosing and appointing an ASP covers selection. For AR we suggest adding three questions: how your billing system hands invoices and credit notes to the ASP, how transmission failures are reported back to the AR team, and how the provider supports your timing controls. These are editorial prompts, not official criteria, and we name no providers.

Article 8 agents and Article 9 self-billing

When an agent issues for you

Article 8 allows an agent acting on behalf of a principal to issue and transmit the document for that principal. If an agent bills your customers on your behalf, record the arrangement in your customer and contract data so that AR knows which sales are invoiced by someone else and can reconcile them. The text we read does not describe how the agent and principal appear on the document, so we do not describe it here.

When your customer issues for you

Article 9 allows the Recipient to issue an Electronic Invoice or Electronic Credit Note on behalf of the Issuer only where both the Recipient and the Issuer are Registrants, and in accordance with the conditions in the VAT Executive Regulation or as otherwise determined by the Minister. For a seller whose customers raise self-billed invoices today, the first step is a customer-by-customer check of VAT registration on both sides. Where either party is not a Registrant, Article 9 does not allow self-billing, so your business would need to issue its own documents. We have not reviewed the VAT Executive Regulation conditions and do not summarise them. Our self-billing guide walks through Article 9 in detail.

Sales the system does not cover

Sales inside a Tax Group

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. If your business is a member of a VAT Tax Group, sales to other members of the same group fall within that temporary exclusion. Sales to customers outside the group are not covered by it, so the Issuer obligations above still apply to them unless another exclusion does. Flag fellow group members in the customer master so that intra-group billing and external billing can be routed differently. We do not calculate the end date of the 24-month period. Our Tax Group exclusion guide explains the rule in more detail.

B2C sales and mixed businesses

Article 5(2) of Decision 244/2025 provides that B2C transactions, and persons engaged exclusively in them, are not subject to the system until a ministerial decision determines otherwise. A business that sells only to consumers falls within the person-level part of that rule. A mixed business, selling to both businesses and consumers, is not engaged “exclusively” in B2C transactions on our reading, so its non-B2C sales need their own scope check. B2B and B2C are editorial labels here; the decisions we read do not define B2B, and we have not confirmed the legal definition of a B2C transaction. Our B2C exclusion guide explains the rule.

Other exclusions and voluntary participation

The replaced Article 4 also excludes certain transactions, such as certain airline documents and certain VAT-exempt or zero-rated financial services; see our sector exclusions guide. Article 4(3) lets a Person take part voluntarily for otherwise excluded transactions, in which case the decisions apply to it mandatorily except those on violations and penalties. Decide that deliberately rather than by default.

Dates by category

The obligations above apply from the implementation dates in Article 5(1) of Decision 244/2025, with Article 5(1)(a) as replaced by Decision 66/2026. The revenue-based dates apply to persons subject to the system, and Government Entities have their own timetable.

  • Annual revenue AED 50 million or more: ASP appointment by 30 October 2026; eInvoicing implementation by 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: ASP appointment by 31 March 2027; eInvoicing implementation by 1 July 2027. Decision 244/2025, Article 5(1)(b).
  • Government entities: ASP appointment by 31 March 2027; eInvoicing implementation by 1 October 2027. Decision 244/2025, Article 5(1)(c), which applies to Government Entities.

Our deadlines guide and the key dates summary explain the categories. For AR, the ASP appointment date is the practical deadline for billing-system integration, because invoices cannot be transmitted through the system without an appointed provider.

What we have not been able to confirm

  • The number of days in the VAT Law timeline referred to in Article 6(4).
  • The ministerial reporting timeline under Article 6(6).
  • The Article 7 technical specifications and data fields, including how agents, principals and original invoice references appear.
  • How a credit note must reference the original invoice, and how price increases and partial returns are handled.
  • How the penalties are applied in practice. The amounts are set in Cabinet Decision 106/2025: AED 100 per Electronic Invoice or Electronic Credit Note not issued and transmitted on time, up to AED 5,000 per calendar month, and AED 5,000 for each month or part of a month of delay in implementing the system, including late ASP appointment. 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; see our Cabinet Decision 106/2025 penalties guide.
  • Which days are federal holidays for Business Day counting, the VAT Executive Regulation self-billing conditions and the content of Article 10.

We state these gaps rather than filling them with estimates. Check the official texts on the MoF eInvoicing programme page and ask a qualified adviser. We do not name, compare or price providers or billing software.

An accounts receivable checklist

This is an editorial planning list, not an official checklist or a legal test.

  1. Confirm scope and category. Use the scope guide and note your ASP appointment and implementation dates.
  2. Inventory billing flows. List every system and channel that produces invoices or credit notes, including manual ones.
  3. Clean customer master data. Record VAT registration, Government Entity status, Tax Group membership, consumer status and agent arrangements.
  4. Appoint an accredited ASP. Confirm current accreditation under Decision 168/2026 and how your billing system connects to it.
  5. Set the timing rule. Decide which timeline applies to your business under Articles 6(4) and 6(5), capture the Date of Business Transaction including advance payments, and agree how Business Days are counted.
  6. Map credit note triggers. Link cancellations, price reductions, refunds and error corrections to an Electronic Credit Note.
  7. Review agent and self-billing arrangements. Record Article 8 agents and check that both parties are Registrants for any Article 9 self-billing.
  8. Test and assign owners. Run issuing, transmission and credit note scenarios with the go-live testing checklist, fit the work into the readiness project plan and score your preparation with the free readiness check.
  9. Reconcile every month. Compare issued Electronic Invoices and Credit Notes with the sales ledger at period end, as described in our month-end reconciliation guide.

Frequently asked questions

Can we keep emailing PDF invoices to in-scope customers?

Article 6(1) requires the Issuer to issue and transmit an Electronic Invoice through the system, and Electronic Invoices are defined as structured electronic documents. On our reading, a PDF sent by email does not replace that for an in-scope sale.

How long do we have to issue an Electronic Invoice?

A Registrant Issuer follows the VAT Law timeline under Article 6(4). Article 6(5), as replaced by Decision 197/2026, sets fourteen Business Days from the Date of Business Transaction, subject to Article 6(4). We have not confirmed the number of days in the VAT Law timeline.

When must we issue an Electronic Credit Note?

On cancellation, reduction of the agreed consideration, return of consideration in full or in part, and administrative or numerical error, under Article 6(2).

Can our customer invoice itself on our behalf?

Only under Article 9, where both parties are Registrants and the VAT Executive Regulation conditions, or conditions set by the Minister, are met.

Do we invoice other members of our Tax Group through the system?

Business Transactions between members of the same VAT Tax Group are Excluded Transactions for 24 months starting 1 January 2027. Sales to customers outside the group are not covered by that exclusion.
