Streamline Direct Debit Processing with AUDDIS and Automated Validation
Read time: 3 minsLast updated: 15 April 2025
Direct Debits are a core part of how you move money. But even small data errors - wrong account numbers, unsupported account types - can cause rejections, delays, and unnecessary admin work.
AUDDIS (Automated Direct Debit Instruction Service) helps automate the setup and management of Direct Debit mandates. It's essential for reducing manual tasks. But to use AUDDIS effectively, your data must be accurate. That's where validation becomes critical.
Why Validation Matters in Direct Debit Processing
Common errors in Direct Debit submissions - like “No Account,” “Invalid Account Type,” or “Bank Will Not Accept Direct Debits” - often trace back to incorrect bank details. These issues can:
- Lead to rejected payments
- Create cash flow disruptions
- Increase admin time spent on corrections
- Damage customer trust
Finance teams can’t afford that kind of friction.

How Mintly Helps You Catch Errors Early
Mintly's validation tool is built to handle the specific requirements of AUDDIS. It checks sort codes, account numbers, and account types before submission. If there's a mismatch or the account can't accept Direct Debits, it flags it immediately, so you can fix it before the error causes a failed payment.
You stay compliant.
You reduce the risk of rejection.
You save time on post-processing fixes.
Whether you're dealing with Error L (incorrect payer details) or Error G (Direct Debits not accepted on account), Mintly helps you catch it early.
Optimise Your AUDDIS Workflow
To run Direct Debit operations efficiently, build validation into your process:
- Always verify account data before submitting a mandate
- Stay familiar with common AUDDIS error codes and what they mean
- Use a validation tool that aligns with Bacs standards
Mintly's validation engine is designed for finance teams like yours. It's fast, accurate, and easy to integrate.
