If a paid bill is voided, either by staff or by the system, it may result in a negative balance on the patron’s account. To close negative bills, you can adjust the balance to zero, add a bill entry to the negative line item, or refund the balance amount.
On occasion staff may need to manually void a payment in order to trigger the refund. See the section called “Voiding a Paid Bill”.
The most common scenario resulting in a negative balance is a lost item that has been paid for being returned within the library’s refund interval. See LINK for information on lost settings.
Select the line for the refund and go to Actions → Refund.
Click OK/Continue.
In the summary section of the Bills tab you will see the amount you are refunding reflected in the Refunds Available and Pending Payment fields.
Click Apply Payment.
