Automated Direct Debit Instruction Service

AUDDIS enables organisations to send new Direct Debit Instructions to their customers' bank electronically, instead of in paper format. It is mandatory for all new service users that submit direct to Bacs.

AUDDIS automates the transfer of Direct Debit Instructions from collecting organisations to the paying banks and building societies via the Bacs service. The organisation keeps the original signed Instruction and electronically sends the details to the customers' bank to validate and, if accepted, set up the Instruction on its database.

By automating the exchange of Instruction details between organisations and banks, manual handling is reduced leading to fewer errors. Instruction details are processed faster and more efficiently, eliminating the need for the customer's bank to re-key the details.

Any invalid Instructions rejected by the paying banks and building societies are returned via the Bacs service using ADDACS​.

Service users who wish to use the Paperless Direct Debit service must become AUDDIS compliant first.


  • Reduced paper handling
  • Your customers enjoy a better quality service through fewer manual keying errors
  • Overall, the Direct Debit Scheme is improved, as is its public image.
