Resolution

  • Sometimes when using custom pages instead of standard pages, error messages appear.

    • Testing of custom pages should be conducted in Sandbox environment before moving them to live environment.

  • First, check that the AvaTax bundle is up-to-date

  • Next, see if you are able to process the transaction by using a Standard Form

    • If the Standard Form is able to calculate tax, compare the Standard and Custom Forms.

    • Make sure all required fields for tax calculation are included on the Custom Form.
