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.
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.
