How can this happen?
Automatic Payments configuration settings contain: Maximum Days Past Due - This is if past due payments are enabled to be scheduled, set the maximum days allowed. When greater than this value payments will need to be scheduled manually.
This setting is designed to ensure you don't accidentally bill old invoices by automatic payment so we recommend completing either option 1 or 2.
There are three options available to resolve this issue:
Locate the invoices in Outstanding Payments > Actions > Pay Now by Credit Card
This will enable you to process payment via a Credit Card immediately
Locate the invoices in Outstanding Payments > Actions > Schedule a Bank Debit
This will enable you to schedule the invoice to be paid on a particular day via a bank account
Change your Automatic payments configuration settings to increase the Maximum Days Past Due > locate the invoices in Auto Payments > Reset & Re queue
