AUDDIS

AUDDIS stands for Automated Direct Debit Instruction Service. It is a business to bank messaging service. It enables Service Users (the collecting organisation receiving the Direct Debit funds), to send new Direct Debit Instructions (DDIs) to their customers’ bank or payment service provider (PSP) electronically. This replaces the paper-based system where Service Users would post completed paper DDIs to the bank. It is mandatory for all new Service Users that submit direct to Bacs to use AUDDIS.
