Setting up & using Single Sign On

Single Sign On (SSO) enables you to use a single login to sign into multiple platforms. Fathom allows you to authorise Xero and/or Intuit QuickBooks SSO for your Fathom account so you can log in to Fathom with your Xero or Intuit credentials.

To set up SSO on your Fathom account, simply go to the Fathom login page ( From there,

  1. Select either the Xero or Intuit (QuickBooks) SSO option under the regular ‘Log in’ button

  2. Depending on the option you selected, you’ll be taken to either the Xero or Intuit/QuickBooks login page and be asked to log in

  3. Once you’ve logged in to your Xero or Intuit, you’ll be taken back to Fathom and asked to enter in your email associated with your Fathom account. Select ‘Next step’.

    💡Pro tip: The email will be auto-filled with your Xero or Intuit credentials, but you can enter in another email.
