In the Mark to pay section, in the lower part of the window, you select/enter which invoices have been paid. When you have entered the Invoice number, information about the invoice such as Customer code and Paid amount is loaded.
If the invoice is linked to an order that has a payment plan, you will to the right of the customer name see which type of partial invoice it concerns: Advance, Delivery or Subsequent
In the Paid amount field you can see the Rest amount of the invoice, but this can be changed. If a smaller amount has been paid, you can enter a Difference code.
If the invoice was made out in a foreign currency, you can also see the Currency code for the foreign currency and the Initial rate in which the invoice was recorded. In the Current rate field you enter the rate of the payment date. The rate difference is calculated as the difference between the two rates. The Bank charge, if any, is entered in a separate field.
Under Interest you will see interest amount if the invoice has been paid after the due date.
The fields Payment date and Payment method are automatically filled in according to the corresponding fields under Payment settings. Due date, cash discount date, and cash discount in percent, are displayed here. Under the Comment button you can load or update comments linked to the invoice.
You can control and adjust the coding of the payment by clicking on the Coding window button.
Finally, the invoice is registered as paid when you click the Move button or use the F9 key or the plus key (+) on the numerical keyboard. The invoice will then disappear from this section and instead be visible in the Marked to pay section.
