XRechnung BR-DE-13 (legacy): delivery date or invoice period
Note: BR-DE-13 is no longer part of the current XRechnung 3.x rule set — modern validators do not emit this code. Historically it covered the recommendation to provide either the actual delivery date (BT-72) or an invoice period (BG-14). That information is still good practice but is now checked through the EN 16931 core rather than a dedicated BR-DE rule.

Affected field
cac:Delivery/cbc:ActualDeliveryDate (BT-72) or cac:InvoicePeriod/cbc:StartDate + EndDate (BG-14)
Cause
The invoicing system does not export a delivery date (common for service invoices) and no invoice period is set.
Fix
Add either the delivery date (for goods) or the invoice period start/end dates (for services or ongoing deliveries).
<!-- No Delivery and no InvoicePeriod element present -->
<!-- Option 1: Delivery date --> <cac:Delivery> <cbc:ActualDeliveryDate>2026-05-15</cbc:ActualDeliveryDate> </cac:Delivery> <!-- Option 2: Invoice period --> <cac:InvoicePeriod> <cbc:StartDate>2026-05-01</cbc:StartDate> <cbc:EndDate>2026-05-31</cbc:EndDate> </cac:InvoicePeriod>

Frequently asked questions
What about service invoices?▼
For services there is usually no physical delivery date. Use the invoice period (InvoicePeriod) with start and end dates instead.
Can I use the invoice date as the delivery date?▼
Technically yes, but it is not semantically correct. Use the actual date the service was performed or goods were delivered.
