How to handle duplicate payments?

← Banking and EBICS FAQ

A customer has paid twice. Applying a credit balance strategy in this case is currently not supported, and automatic balance assignment with balance records created through integrating JustOn Billing & Invoice Management with JustOn Cash Management is not allowed.

So how can I use a duplicate payment for a new entry?

Manual assignment

As a straightforward solution, you can use the manual settlement feature – associating the "free" payment to an open entry. If required, you may have to recreate the related invoice PDF to reproduce the completed settlement.

1. On the relevant payment, click Settle Manually.

   This opens the Edit Assignments dialog, which allows you to relate the payment with an entry.

2. Click + Assign Entry to select the target entry.

3. Save the changes to complete the settlement operation.
4. Optionally, navigate to the related invoice record and click Recreate PDF.

Automatic assignment

In integrations with sales portals or web shops, the combination of JustOn Billing & Invoice Management with JustOn Cash Management allows for handling pre-payments automatically.

There are two possible scenarios:

• The sales portal integration creates entries based on sales order data. As buyers pay, the entries are settled using the corresponding payments.

  Now creating and finalizing invoices (based on the same sales order data) must relate the invoices with the existing entries, and associate the existing payments to the invoices to set them Paid.

  To this end, you use the assignment key on entries and the entry assignment key on invoices. With the same key, the software will associate an existing entry with a new invoice.

  For an outline of this scenario, see Prepaid Entry Assignment on Invoice Finalization.

  For information on enabling this behavior, see Enabling Entry Assignment.

• The sales portal integration creates payments. Creating (and finalizing) invoices from the sales order data must relate the produced entries with the existing payments, settling them, and associate the existing payments to the invoices to set them Paid.

  JustOn Cash Management compares the payment assignment keys on entries and the assignment keys on payments to relate entries with payments. To pass this key from a new invoice to the entry, you set the field PaymentAssignmentKey on the invoice. On finalization, JustOn Billing & Invoice Management copies the specified value to the produced entry.

  For an outline of this scenario, see Payment Assignment on Invoice Finalization.
