UAE eInvoicing dispute resolution and invoice rejection management: legal framework, ASP status workflows and commercial remediation

Electronic invoicing changes how an invoice travels between a supplier and a buyer, but it does not stop the two businesses from disagreeing about price, quantity, delivery or the terms of a contract. This guide is about what happens when an invoice has been exchanged and one side does not accept what it says: how to escalate the disagreement, how to reach and record an agreed outcome, and when that outcome has to be reflected in an Electronic Credit Note. It keeps to what the official texts we have read actually say, and it labels our own practical suggestions as editorial. Where we could not verify something, we say so in a separate section rather than guessing.

How this guide fits with the rejection and intake guides

Three of our guides deal with invoices that are not straightforward, and each has a different job:

• Intake and validation. The invoice intake and validation workflow covers the checks a buyer runs when an invoice first arrives: is it the right document, for the right entity, with the data the business needs to process it.
• Rejections and discrepancies. The invoice rejection and discrepancy workflow covers triage: classifying a problem, routing it to the right owner, and keeping exchange status separate from commercial and tax status.
• Commercial disputes (this guide). This page picks up where triage ends. It covers disagreements that need escalation between the two businesses, a negotiated outcome, and a documented settlement, together with the corrective document that the settlement may require.

If you are still working out what went wrong with an incoming invoice, start with the rejection and discrepancy workflow. Come back here once you know the problem is a genuine commercial disagreement rather than a data or exchange error.

The official texts that matter, and what they say

None of the official texts we have read sets out a dispute resolution procedure between a supplier and a buyer. What they do set are the rules around the documents that a dispute may affect. We have read the following and describe them only at the level we have verified.

Ministerial Decision No. 243 of 2025, Article 6

Under Article 6(2) of Decision 243/2025, the Issuer issues and transmits an Electronic Credit Note to the Recipient in four cases: (a) cancellation of the Business Transaction; (b) a reduction of the agreed consideration for any reason; (c) a full or partial return of the consideration; and (d) an administrative or numerical error. On timing, Article 6(4) points an Issuer that is a Registrant to the timeline in the VAT Law (Federal Decree-Law No. 8 of 2017), and Article 6(5), as replaced, sets fourteen Business Days for other cases. Our credit notes and price adjustments guide works through each case with editorial scenarios.

Ministerial Decision No. 197 of 2026

Decision 197/2026 amends Decision 243/2025 and is in force from 1 October 2026, according to the Ministry of Finance announcement of the amendment. Within the scope we have recorded, it replaces Article 4 (exclusions), replaces Article 6(5), replaces Article 11 (records are kept for the period under the Tax Procedures Law) and repeals Article 12 (System Failure). It does not add a dispute procedure. Our Decision 197/2026 guide describes these changes in more detail.

Cabinet Decision No. 106 of 2025

Cabinet Decision 106/2025, which we read in the official English text on 24 October 2026, sets the administrative penalties for violating the eInvoicing legislation under the Tax Procedures Law. It does not apply to a Person participating on a voluntary basis. The amounts most relevant to an open dispute are covered further down this page, and our penalties guide sets out the full table.

Where a dispute sits in the 5-corner exchange

The Ministry of Finance describes a 5-corner model: the supplier (C1), the supplier's accredited service provider (C2), the buyer's accredited service provider (C3), the buyer (C4) and the Federal Tax Authority (C5). C2 transmits the invoice to C3, both ASPs report tax data to the FTA, and Message Level Status (MLS) messages flow back to the supplier and the buyer. Our 5-corner model and PINT AE guide sets out each step as described in the official sources.

Both MoF sources say that if C3's validation fails, C3 sends a negative status to C2 and to the FTA and does not report tax data. That is an exchange event between systems, not a commercial decision by the buyer. A commercial dispute usually starts later: the invoice has passed validation and reached the buyer, and someone in the buyer's business disagrees with what it says. Keeping those two situations apart is the single most useful habit in dispute handling, because a successful exchange does not mean the buyer agrees, and a buyer's agreement does not prove that the exchange completed.

Technical rejection versus commercial dispute

As an editorial working distinction, we suggest treating an issue as technical where the invoice did not pass validation or did not reach the buyer, and as commercial where the invoice arrived but the buyer contests the price, the quantity, the delivery, the service quality or the contract terms behind it. A technical issue is resolved with the supplier's ASP and data owners, usually by correcting and resending. A commercial issue is resolved between the two businesses, and its outcome may or may not require a new document. Mixed cases happen: a wrong tax category or legal entity name can be both a data problem and a commercial one, and should be escalated to the tax team before anyone agrees a figure.

A practical escalation path for commercial disputes

The following sequence is editorial. It is not an official procedure, and the timings in it are internal targets your business sets, not statutory deadlines.

1. Confirm the exchange position. Before arguing the substance, check with your ASP that the invoice was actually delivered and what status messages were received. This rules out a technical problem being treated as a dispute.
2. Open one case with one owner. Assign a named coordinator on each side. On the buyer side this is usually accounts payable with procurement; on the supplier side, accounts receivable with the account manager.
3. State the disagreement precisely. Record which invoice line, field or amount is contested, the value invoiced, the value the disputing party expects, and the evidence for it (order, contract, delivery record, prior correspondence).
4. Escalate in stages. Agree in advance who decides at each level: operational staff first, then finance and commercial managers, then legal or external advisers for material contractual disputes. A written escalation matrix agreed with key trading partners saves time later.
5. Agree the outcome in writing. The outcome is typically one of three: the invoice stands as issued; the supplier reduces or cancels the amount; or the parties agree that the invoice contained an error. Record who agreed it and when.
6. Map the outcome to a document. If the outcome falls within one of the four Article 6(2) cases, the Issuer issues and transmits an Electronic Credit Note. If the invoice stands, no corrective document follows from the dispute itself.
7. Close and file. Link the case record, the settlement and any credit note together and keep them with your eInvoicing records.

Payment holds during a dispute are a matter for your own contract terms and payment controls. Our accounts payable recipient guide covers the buyer's side of the process more generally.

Documenting the settlement

A dispute that ends in a phone call leaves nothing to show an auditor or a future colleague. We suggest that every closed case carries: the original invoice identifier; the case opening date and the parties involved; a short statement of the disagreement; the evidence each side relied on; the agreed outcome and who approved it; the identifier of any Electronic Credit Note that resulted; and the date the case was closed. Article 11 of Decision 243/2025, as replaced by Decision 197/2026, requires records to be kept for the period under the Tax Procedures Law. We have not recorded the number of years here; our record-keeping and archiving guide explains what is and is not confirmed.

When a settlement changes the invoice: Article 6 credit notes

Most negotiated outcomes that reduce what the buyer pays will fall within Article 6(2): a cancelled transaction, a reduced price, a returned amount or a corrected error. The Issuer (the supplier) issues and transmits the Electronic Credit Note, within the Article 6(4) or Article 6(5) timeline that applies to it. The buyer cannot issue the credit note in the supplier's place, except where a self-billing arrangement applies under Article 9. How a credit note should reference the original invoice, and whether a partial credit or a full credit followed by a new invoice is the better route, are not settled by Article 6; agree that with your ASP and tax adviser. Our credit notes guide and Article 6 obligations guide go further.

Penalty exposure while a dispute is open

Cabinet Decision 106/2025 does not contain a penalty for disputing an invoice. Its table does, however, include amounts that a long-running dispute can touch indirectly:

• Failure to implement the system, including failing to appoint an ASP within the Minister's timeline: AED 5,000 for each month of delay or part of a month (row 1).
• Failure to issue and transmit an Electronic Invoice or Electronic Credit Note within the prescribed timeline: AED 100 per document, up to AED 5,000 per calendar month, written for the Issuer. If a settlement triggers a credit note, the supplier should not let the dispute paperwork delay it.
• Failure to notify the Authority of a System Failure, or the ASP of changes to data registered with the Authority, within the timeline: AED 1,000 per day of delay or part of a day.

The decision does not apply to persons participating on a voluntary basis. How the FTA applies these amounts in a particular case is not confirmed here. Outages are a separate topic covered in our system failure and continuity guide.

Not confirmed: points we could not verify

The following are not confirmed in the sources we have read, so this guide does not state them as fact:

• the official list of Message Level Status codes, their meanings, and the legal effect of a negative status or of a buyer rejecting an invoice;
• any deadline for resending a corrected invoice after a validation failure;
• whether, or how, an ASP or the FTA checks buyer identifiers against registration records during exchange;
• whether Article 6(5) covers credit notes in the same way as invoices, and how Business Days are counted around holidays;
• the date of Official Gazette publication of Cabinet Decision 106/2025 (and therefore its exact entry-into-force date) and how the FTA counts or waives penalties;
• which provision now sets the System Failure notification timeline after Article 12 was repealed;
• any official dispute resolution or mediation channel specific to eInvoicing.

For the exchange framework itself, see the Ministry of Finance UAE Electronic Invoicing Guidelines V1.1 and the MoF eInvoicing programme page.

Frequently asked questions

Does a buyer rejecting an invoice cancel it?

The texts we have read do not say that a buyer's rejection cancels an invoice, and we have not verified the legal effect of a rejection status. Cancellation of the Business Transaction is one of the four cases in which the Issuer issues an Electronic Credit Note under Article 6(2), so if the parties agree to cancel, the credit note is the document the text names.

Who issues the credit note after a settled dispute?

The Issuer, meaning the supplier, issues and transmits it to the Recipient, except where a self-billing arrangement under Article 9 applies.

How long does the supplier have to issue the credit note?

Article 6(4) points a Registrant Issuer to the VAT Law timeline; Article 6(5), as replaced by Decision 197/2026, sets fourteen Business Days for other cases. Whether Article 6(5) applies to credit notes in the same way is not confirmed, so check with your adviser.

Is a validation failure the same as a dispute?

No. A validation failure is an exchange event handled with the ASP, usually by correcting and resending. A dispute is a disagreement between the businesses about what the invoice says. Use the rejection and discrepancy workflow for the first and this guide for the second.

Is there a penalty for disputing an invoice?

No row in the Cabinet Decision 106/2025 table names disputes. The rows for late Electronic Invoices and Credit Notes apply to the Issuer, so a supplier should not let a settled dispute delay a required credit note.

How long should we keep dispute records?

Article 11, as replaced, requires records to be kept for the Tax Procedures Law period. We suggest keeping the dispute file with the invoice and any credit note so they can be produced together.
