How to fix ibr-030 in UAE e-invoicing

What is ibr-030?

ibr-030 is a fatal validation rule in the UAE's Peppol PINT-AE e-invoicing specification, inherited from the shared Peppol layer. It is checked against each invoice line and belongs to the Dates & periods rule group. An e-invoice that fails ibr-030 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

If both Invoice line period start date (ibt-134) and Invoice line period end date (ibt-135) are given then the Invoice line period end date (ibt-135) MUST be later or equal to the Invoice line period start date (ibt-134).
UAE impact: this is a fatal rule from the shared Peppol layer, enforced in the UAE profile — an invoice failing it is rejected at the Accredited Service Provider gateway before it ever reaches the FTA. A rejected invoice means resubmission delays, and late transmission risks the AED 100-per-invoice penalty under Cabinet Decision No. 106 of 2025.
