- The document is not being closed by QuickBooks before Avalara AvaTax attempts to write to the document to add tax

- Use the Save and Close or Save and New options at the bottom of the invoice

- QuickBooks may be hung up processing the save, restarting QuickBooks (or the computer) may be necessary.
