AUDDIS stands for Automated Direct Debit Instruction Service and is operated by Bacs. An AUDDIS Direct Debit solution enables organisations to send Direct Debit Instructions to their customers’ banks through a payment service provider (PSP). That provider will hopefully be Interbacs! It has significant benefits over its predecessor. Direct Debits are the most common means for a company to collect payments from customers. The original paper-based Direct Debit system was the most popular payment collection method until the late 90s, when service users could electronically submit DDI’s. Its older form, a paper mandate, was a lengthy process that made businesses wait for payments to be cleared. This method involved the manual process of having the mandate taken to the bank and then to Bacs. This process has many variables which make it risky, as the mandate could be lost or found to be incorrect. Nowadays, businesses can submit files electronically to Bacs. Removing risk from the procedure and streamlining the Payment Process to a few clicks, rather than a hand-delivered letter. We can offer software that is beneficial to your time and wallet. ## How can an AUDDIS direct debit solution help your business? - AUDDIS direct debit solutions deliver a range of benefits to customers, service users and banks. It is the preferred method to deliver payments, as it makes processing Direct Debit Instructions faster, cheaper and more streamlined. - Reduces paperwork across the business. Helping your company lower its carbon footprint. - Allows easy identification of invalid accounts, as well as unpaid Direct Debits. Making reconciliation of issues faster and easier. - Reduces set up costs per individual instruction. You will not be paying postage costs to migrate payment information; you can then pass these savings onto your customer. - Streamlines overall processing, boosting productivity and allowing your business to focus on growth in other areas. - Speeds up the time between a bank receiving and accepting a Direct Debit Instruction.
