Five common Bacs file mistakes

April 12, 2023

When it comes to Bacs processing, errors within files can be expected – however, some mistakes are more common than others and can easily be avoided. By avoiding these common Bacs file mistakes, you can save time and ensure successful transactions without any issues. Here are the most common Bacs file mistakes to watch out for.

1. Missing mandatory data fields

All Bacs files must include six mandatory fields of data. These are the payers' sort code, account number, account name, amount, user reference and transaction code/Bacs code. While other data can be added if necessary, these six fields are essential. Make sure to include them in your files to avoid any issues.

2. Invalid sort code/account number

Sort codes and account numbers must be specific lengths, and leading zeroes must not be removed. Invalid characters, such as letters or symbols, should also be removed. Keep these guidelines in mind when working with your Bacs files to avoid any errors.

3. Values in an AUDDIS File

In an Automated Direct Debit Instruction Service (AUDDIS) file, values above 0 will cause an error that prevents the file from being submitted to Bacs. New instructions and cancellations must be set at zero. Values above zero are for debits and credits only.

4. Commas within payee names

A comma within a payee name can easily ruin a .csv file. These are most often found in joint accounts or when a family name is in front of a given name. That little comma can throw out the rest of the line and cause havoc in the file, so be mindful of this when creating your Bacs files.

5. File format discrepancies

File format discrepancies can occur when a file is extracted from a CRM/database in the wrong format or when a file is amended at the service user's end. For example, a file created in Excel but amended in Notepad may automatically save in a new format. Be sure to check your file formats to avoid any unexpected issues.

For many of us, direct debits are a key part of our everyday finances. From paying bills to keeping our gym membership up to date, we rely on direct debits to help us meet our financial commitments with the minimum of fuss. For businesses needing to debit customers on a regular basis, a direct debit makes sense. Indeed, in the year to February 2025, almost five billion direct debit transactions took place, totalling £1.49 trillion, underlining just how accustomed we are to using direct debit. But when you’re looking for a solution to take regular payments from customers, there are a number of options out there that all seem to offer the same end result. However, there are some very good reasons as to why you should partner with an Bacs (Bankers Automated Clearing Services) approved software provider such as Mosaic Software by ClearDebit , which is one of only 13 Bacs-approved software providers in the UK .
