Search / display all payments for an invoice
To display all payments for a specific invoice, click in the invoice archive under Actions on "Payment history":
Alternatively, you can search for all payments for an invoice in the incoming payments. Enter the desired invoice number in the column "to Inv-ID":
Please note: only the selected period will be searched:
If you are not sure in which period the payment was received, it may make sense to search all incoming payments. First select "All" and then click on "Search". Then enter the desired invoice number again.
