KSEF-BUS-303 HEURISTIC Warning KSeF Guard Only
Advance and settlement invoice amount inconsistency
Niespójność kwot zaliczkowych i rozliczeniowych
Problem
The settlement invoice (ROZ) amount exceeds the sum of the related advance invoices (ZAL) in the batch. This may indicate missing advance linkage or a partial-advance scenario (Art. 106f).
How to Fix
Verify the linkage between advance and settlement invoices. The rule is a Guard heuristic — a partial-advance scenario per Art. 106f is legitimate and may trigger this alert.

“If the invoice referred to in sec. 1 does not cover the entire payment, in the invoice issued after the delivery of the goods or performance of the service, the sum of the values of the goods or services is reduced by the value of the partial payments received, and the tax amount is reduced by the sum of the tax amounts shown on the invoices documenting receipt of the partial payments. The invoice referred to in the first sentence shall also contain the numbers identifying in the National e-Invoice System the invoices issued before the delivery of goods or performance of the service, and in the case of invoices other than structured invoices — the numbers of those invoices.”
