Once you've scheduled a payment or if you've enrolled in Auto Pay, you can change the payment details and payment method, or cancel the scheduled payment unless it has already started processing. To do so, follow the steps below:
Go to the 'Invoices' page on your main dashboard and click ‘Details’ for the relevant invoice
Click the ‘Edit payment details’ button. If the invoice is enrolled in Auto Pay, instead you’ll see ‘Edit Auto Pay details’
In the window that opens, you can change the payment method, and the payment date, or cancel the payment altogether
If you're making changes, select the 'Save' button to finalize your changes
Note, that if you cancel a scheduled payment, the status of the invoice will revert back to 'To Pay' or 'Overdue' depending on the due date of the invoice.
