You can pay or refund "ad hoc" charges without linking to a borrower. To do this:
Once a charge is added to the Applied charges list, you can click the cursor in the Amount column and/or the Qty column to change the value.
If you wish you can apply the same charge multiple times with a different amount for each one.
You can click Add and then Add Refund to add a refund to the Applied charges list.
In the charge parameters you can specify which charges you'll see on the "main" dialog, and the default amount. Click Show all charges to list all the ad hoc charges.
You can also add ad hoc charges for a borrower.
