There are two ways to edit an existing payment plan for a registrant — through Banking Transactions or directly from the participant record.
Option 1: Edit via Banking Transactions
Go to Banking Transactions > Payment Plans
Find the registrant and click Actions > View
In the Edit Payment Plan modal, you'll see the plan details and a breakdown of all invoices
Click Edit next to any upcoming invoice to update the amount or date, or click Delete to remove it
Click Add to add a new invoice if needed
Option 2: Edit via Participant Record
Go to Registration > Participants
Click on the participant's name to open their record
Scroll down to the Payment Information section
Click View next to Paying by Payment Plan
Edit the invoices as needed
Note: Changing the base fees on a participant record will not update the scheduled payment amounts on the plan. Make sure to edit the payment plan directly if adjustments are needed.
