Modernizing Payment Systems: An Approach to BACS AUDDIS Implementation with SAP S/4HANA

Our team at Zanders has been at the forefront of implementing BACS AUDDIS (Automated Direct Debit Instruction Service) with SAP S/4HANA, helping clients to streamline their direct debit management while ensuring regulatory compliance.

Why BACS AUDDIS Matters

BACS Direct Debit is the UK's electronic direct debit service, enabling organizations to collect payments directly from customers' bank accounts. This service offers numerous advantages, including predictable cash flow, reduced administrative overhead, and improved operational efficiency.

The implementation of AUDDIS enhances this process by allowing organizations to electronically send Direct Debit instructions to the banking system. This digitization eliminates paper-based processes, reduces operational costs, and improves overall processing speed.

The Advantage

Our approach for AUDDIS implementation with SAP S/4HANA provides a bespoke solution that supports AUDDIS requirements, built on top of the standard SAP S/4HANA functionality. What sets our approach apart is our deep expertise in complex, mission-critical financial system implementations specifically tailored for market leading organizations.

The solution development leverages the full range of SAP's Direct Debit (DD) capabilities supplemented by our extensive experience in Treasury and Payment systems. This creates a seamless integration with existing SAP finance processes while ensuring full compliance with BACS standards.

The Solution

The solution developed supports the full cycle of BACS Direct Debit (DD) mandate management in SAP, from new mandate registration to mandate amendments, cancellation, and dormancy assessment.

Mandate information and amendments are automatically interfaced in XML format (PAIN.008) in compliance with BACS requirements, transmitting from the SAP Payment Hub to BACS through a BACSTEL-IP service provider.

Furthermore, to ensure a smooth and streamlined direct debit collection process, the custom solution enhances SAP’s automatic payment program with additional features.

These include verifying the validity of the customer or alternative payee’s mandate status at the payment proposal stage, considering DD collection lead periods.

This ensures that only customers with an active mandate status are included in the payment run. In addition, SAP’s Data Medium Exchange (DME) engine has been extended to include the mandatory mandate reference attributes in the bank interface.

Our Four-Phase Implementation Approach

 Every AUDDIS implementation follows four key stages:

1 - Application: The corporate entity applies to its sponsoring payment service provider for AUDDIS approval.

2 - Preparation: After approval, the corporate prepares its internal systems, ensuring software, processes, and infrastructure are in place for AUDDIS integration.

3 - Testing: The corporate submits test files to BACS to validate both compliance and successful transmission.

4 - Go-Live: The corporate transitions to using the AUDDIS service either as a ‘live’ user from the start or by migrating first before going live. This is the final stage of the AUDDIS implementation process, and exactly what this entails depends on whether the corporate is joining AUDDIS with a new Service User Number or with an existing one, and therefore, has a migration (to onboard existing customer mandates to AUDDIS) to complete.

AUDDIS implementation projects require ongoing coordination with Banking Partners, System Integrators and Business Process Teams. This includes the process of creating BACS Service User Numbers, extensively testing bank interfaces for AUDDIS and Direct Debit Instruction files. At go-live, detailed coordination is required to support penny testing.
