If you have a Recurring Plan with an unpaid invoice, you can close that invoice manually. That will prevent the system from attempting to automatically pay the invoice in the future. To close the invoice:
1) Click on the Plans button in your account’s main navigation.
2) Click on the Recurring Plan whose unpaid invoice you wish to close.
3) Scroll to the Invoice section and click on the unpaid invoice you wish to close.
4) Click on the Close button.
