If a Direct Debit's status is Suspended, this normally means that the Direct Debit instruction couldn't be lodged.
You'll need to visit the payer’s CONTRACT UPDATES in their individual profile to determine the particular AUDDIS code received.
The Guide to BACS transaction codes gives guidance on the various codes and action that needs to be taken.
For AUDDIS code B (Account Closed), the customer's bank details will need to be updated before restarting the Direct Debit contract.
📌Note: When a contract is suspended any payments which are due will still show in the future payments due report and calendar view, however these will not attempt collection. To stop the payments from showing you will need to skip or terminate the contract.
