ABA file is used by all major Australian financial institutions to specify payments to be made from one bank account to one or more bank accounts.

The most common way for employers to pay employees is via an ABA file which can be generated through Payroo. Once you have your ABA file, it’s usually a simple matter of uploading it to your business internet banking portal and authorising the payments.

Setting up your business to generate an ABA file

Step 1: Select "Settings" from main menu.

Step 2: Select "Bank Account Settings" under "Settings".

Note: Before filling in the details, please refer to what each of these fields mean at the end of this article after Step 5.

Step 4: Click on "Save" to update the changes.

Once you’ve filled in the Bank account details click 'Save' and you will now be able to generate ABA files from within your pay runs.


Step 5: You will now be notified with a message "Updated Settings".
