E-invoicing · Customer master data
Drop your customer list. Nine checks run in your browser against the buyer fields the Ministry of Finance lists as mandatory, plus the PINT AE rule that rejects an emirate written as a name. You get every record that will fail, the value as it stands, and what it has to become.
No invoices, no amounts, no financial data. Names, TRNs, email, address, city, emirate, country. Nothing is uploaded: this page carries no analytics script, makes no request with your file, and closing the tab removes it. If you would rather see it work first, load the sample list.
One row per customer. CSV from any system. Up to a few thousand rows is fine.
Read only. Nothing is written back to your file and nothing is sent anywhere. The sample list is invented and carries the faults we see in real customer masters.
| Rule | What it checks | Findings | Severity | Source |

Want the fixes made, not just listed? We correct the master data at source, collect the fields nothing has ever held, and run the list again until it passes. Twenty minutes to scope it, no charge.
Or take the fix plan with you. Leave an email and we will send the written plan for all nine checks: what each one rejects, how to correct it at source, and the order to do them in.
Only the email address you type here is sent. Your customer list stays on this page, exactly as promised above.
MD-01 Emirate is one of the seven PINT AE subdivision codes (AUH DXB SHJ UAQ FUJ AJM RAK), not a city name and not an ISO 3166-2 code. HIGH.MD-02 Country code present, two letters, AE for a UAE address. HIGH.MD-03 Buyer name present, and a name rather than an account code. HIGH.MD-04 Buyer address line 1 present. HIGH.MD-05 Buyer city present. HIGH.MD-06 Buyer electronic address present and well formed. HIGH.MD-07 TRN is fifteen digits and not a placeholder. MEDIUM.MD-08 One TRN is not shared by customers carrying different names. MEDIUM.MD-09 No near duplicate customer records once the legal form is set aside. LOW.Checks MD-01 to MD-06 are mandatory buyer fields. The field list is the Ministry of Finance UAE Electronic Invoice mandatory fields, version 1.0 of 23 February 2026; the emirate code rule is IBR-128-AE in the PINT AE v1.0.3 jurisdiction rules on docs.peppol.eu. TRN format is checkable against the FTA TRN verification service. Deadlines: revenue AED 50 million and above appoint an accredited provider by 30 October 2026 and go live 1 January 2027; below AED 50 million appoint by 31 March 2027 and go live 1 July 2027, under Ministerial Decision 244 of 2025 as amended 10 May 2026. Failing to implement the system or appoint a provider carries AED 5,000 per month under Cabinet Decision 106 of 2025.
The buyer electronic address is the one worth looking at first. It is mandatory, and it is the field almost no customer master has ever held, because until now nobody needed it. Already checked your invoices? Run the invoice export check as well. Background: UAE e-invoicing readiness and the five fields to fix first.
