The system does not allow matching multiple payments with a single invoice (advance tax/non-tax invoice or invoice – tax document) at the same time. Each matching must be performed separately.
Procedure:
navigate to the Money – Bank menu,
for each item (record), click the Services button and select the Create payment link option,
match the document amount to the required advance payment (the advance document will be in a partially paid status),
follow the same procedure for the remaining payments in the Bank form until the selected advance document is fully paid,
afterwards, in the same form, you can use the Services button to select the Create invoice from paid advances option,
the system will generate an invoice including the deduction of the advance document (note: if advance documents have not been entered in the system and matched to the bank document, it is not possible to issue an invoice with a deduction using this feature).
