You are intermittently getting the error "[ATS-291]: Object referenced not set to an instance of an object" when trying to calculate tax on an invoice.
- This issue was resolved with v77.00 of AvaTax for QuickBooks.
- If you are on an older version of Quickbooks, upgrade to the latest version of AvaTax for QuickBooks on all workstations and the server (if applicable).
- As a work around, you can also disable the option "Send Item Account to Avalara".
- This is found on the "General" tab in the AvaTax configuration.
