How it works

Simple to connect. Easier to control.

1. Connect

Choose sandbox or production. Enter Account ID, License Key, and Company Code. Test the connection before go-live to validate results with your team.

2. Configure

Set the AvaTax fiscal position, validate addresses, sync exemption codes, and map products or categories so Avalara can apply the correct tax rules and product taxability content across your Odoo workflows.

3. Go live

Run tax inside your Odoo workflows. Review logs, verify transactions, and maintain a clearer audit trail. Odoo supports AvaTax logging and exposes transaction-level details for review, giving finance and tax teams visibility into how tax was determined on each document.
