If you've ever had to pay a group of employees or suppliers one by one through online banking, you know how slow and error-prone it can be.  This is where ABA files help.  They offer a straightforward way to make bulk payments from your business bank account without manually entering each payment.

An ABA file is a plain text document that instructs your bank on who to pay, how much to pay, and when the payment should occur.  It is generated by your accounting or payroll software and uploaded to your online banking portal.  Once uploaded, you can review and authorise all payments.  It’s like sending a batch of instructions to your bank.  This method is handy for recurring payments, such as employee wages or supplier invoices.

For example, if you run a small business with ten employees and a few regular suppliers, your payroll software generates an ABA file every fortnight that details each employee’s pay.  You simply upload that file to your bank, verify the amounts, and approve the payments.  The same process applies to suppliers.  Instead of manually entering each bank account and payment amount, your accounting software simplifies the process.

To reduce the risk of fraudulent deposits, it’s worth implementing a few simple checks.  Make sure only authorised staff can update your system with bank account details.  Have a second person review any changes before the next payment run.  If your software allows it, set up alerts for edits to account information.  You can also keep an audit trail of changes and quickly check payment summaries before uploading the file.  These precautions help protect your business without adding much extra work.

Additionally, it is wise to store ABA files in a secure folder with limited access.  If your software supports it, employ file integrity checks or approval workflows to ensure that nothing has been tampered with before uploading the file.  These steps are handy when multiple people are involved in the payment process.

Thousands of Australian businesses use ABA files every day.  Most major banks and accounting platforms support them, making business life easier.  You don’t need to understand the technical workings of the file; you need to know how to generate it and upload it safely.

The Tax Office does not require businesses to use ABA files, but they are a practical solution for keeping organised and minimising errors.  They also assist with record-keeping, since both your software and bank maintain a copy of the payments.

If your business is still processing payments manually, it may be time to evaluate your accounting or payroll software to see if it can generate ABA files.  Consult with your accountant or bookkeeper, and check with your bank to confirm if your current systems support this feature.  Making this small change can save you a significant amount of time.
