Let me share with you how you can add your account and BSB number on invoices.
Go to Settings ⚙ and select Custom form styles.
Locate the Standard style and select Edit from the Action column.
Select Add your EFT details. Note: It is only possible to add your bank details to the Airy new invoice template. If you can’t see this option, select Change up the template to update your template to Airy New.
Enter your payment details and select Done.
Please note that the newly added payment details will only apply to newly created invoices.
