What causes the BR-DE-18 error?

XRechnung requires Skonto (cash discount) lines to follow a specific format: #SKONTO#TAGE=days#PROZENT=percentage#BASISBETRAG=amount# (BASISBETRAG is optional).

How do I fix BR-DE-18?

Reformat the Skonto line in PaymentTerms/Note to: #SKONTO#TAGE=14#PROZENT=2.00# (for 2% discount within 14 days).

Skonto is the German term for early payment discount. It specifies the discount percentage and number of days within which payment must be made to receive the discount.

Can BR-DE-18 be automatically fixed?

Yes, Invoice Navigator can automatically reformat invalid Skonto lines to the correct pattern.
