There are two easy ways to collect once-off payments from your client’s bank account:
During the Reconcile process
Head to your 'Dashboard' tab
Select the 'Reconcile' button of the past session/class you wish to charge the payment from.
Tick the box 'Make a Payment?'
Ensure the payment amount is correct, and whether you want to email a payment receipt to the client, then select 'Reconcile'. This will save the reconcile and also immediately submit a GoCardless payment request.
Manually record a payment
Select which client is to be charged, ensure that the checkbox 'Make payment using (your client’s name) stored GoCardless Bank Account?' is checked.
Enter the Payment Amount, any notes, and whether you want a payment receipt sent to the client, then 'Save Payment'.
