Simply go to https://account.zipmoney.com.au, and select your account type (Zip Biz) using the login details (Facebook, PayPal or email) you originally signed up with. 

If you are unsure which method you used to signup, you can always request a password reset, by clicking on the Forgot Password link at the sign-in page. 

You should then receive an email that allows you to reset your password and sign in via email. If that still fails, please don't hesitate to contact us and we will be able to assist you.
