Every invoice must contain an issue date (BT-2), the day on which it was issued. Among other things, the date determines the accounting period and when payment terms start running. Without it the e-invoice is not valid.

As of

Who can correct it?

The sender can correct the invoice.

How to fix it

  1. Ask the sender for a corrected invoice that includes the issue date.
  2. If you created the invoice yourself: enter the issue date in your invoicing software and generate the invoice again.

Rule text and source

Paraphrase · The document needs an issue date (BT-2). The CII rule looks for a date with format code 102.

Message to the sender

Subject: Invoice {invoiceNumber} – issue date missing

Hello,

Thank you for your invoice {invoiceNumber}. Unfortunately the electronic invoice does not contain an issue date (rule BR-03), so it cannot be processed. Could you please send us a corrected version?

Kind regards

Example

The issue date is missing. If 3 November 2026 is the actual date of issue, the software exports 2026-11-03 in UBL or 20261103 with format="102" in CII.
