When you are about to register payments, you first enter payment settings in the upper part of the window.
The cursor is first located in the Payment date field, then you enter the Method, Batch total and Text. By entering the Supplier code, the PopUp feature for the consecutive number under Mark to pay will only search for unpaid invoices from the supplier in question.
As new invoices are moved to the Marked to pay section, information regarding Batch rest, Paid quantity, Total paid and a button to see Accounting order is also displayed.
At the top of the window, to the left, you can see the Batch number in question.
