Use the Settings Menu to access Trust Account settings. BPAY file formats are able to be set for each Trust Account.
Options available are:
Commonwealth Bank CommBiz
Macquarie Batch Payment
National Australia Bank
If none of these formats are correct for you, you will be unable to create a BPAY file compatible with your bank. You may select one of the available file format and still process disbursements with the BPAY payment method, but will need to complete the payments at the bank manually.
