How can I enter invoices to reflect historical data?


We finally received an exemption certificate from a few customers and credited the sales tax back to them. Now we have to submit to the state. I know that this has to tied to the original invoice (which was before we went live with AvaTax).

When entering historical data you would like us to file, you will need to add transactions manually to the admin console or import them, with the current liability period as the document dates, so we pick the changes in your liability worksheet.
