BR-03 — Missing issue date

What it means

The invoice issue date is missing. This date fixes when the invoice was issued — the due date and other time-based calculations count from it.

How to fix it

Check that the invoice XML contains an IssueDate element in YYYY-MM-DD format (e.g. 2026-07-13). If the invoice is issued from accounting software (Jumis, Horizon, 1C, etc.), the date usually fills in automatically — check whether it's being dropped in the export settings.

Example

Wrong: the IssueDate element is missing or empty. Correct: <cbc:IssueDate>2026-07-13</cbc:IssueDate>.
