Integration setup
1
Connect to Avalara
Go to Integrations, find Avalara and select “Manage integration”.

2
Assign Avalara tax codes
Start by assigning Avalara tax codes to product tax categories in Sequence (go to Settings > Sales Tax). Once Avalara is connected, tax categories are managed via Avalara tax codes. You can no longer manage tax categories with custom rates.

3
Add tax categories to products
In your product catalogue, assign product tax categories to products. In order to automatically calculate sales tax for a given product, its tax category must be mapped to an Avalara tax code.
You’re now set up to automatically calculate sales tax on invoices via Avalara.

Calculating sales tax with Avalara
Once you’re connected to Avalara, Sequence will calculate sales tax for every draft invoice via Avalara. Whether and how tax is calculated depends on the following factors:- Your merchant location in Sequence (Settings > Merchant > Address)
- Your customer’s location & tax status
- Your tax configuration and tax exposure as reported to Avalara
- The Avalara tax code assigned to a sold product
Tax is automatically calculated and added to the invoice.

Customer address validation via Avalara
Once you’re connected to Avalara, Sequence will validate a customer’s billing address via Avalara. This is required to ensure sales tax is accurately calculated based on the customer’s locale. For customers located outside of the US, Avalara only checks the country.
Troubleshooting
Tax categories not mapped to Avalara tax codes
Tax categories not mapped to Avalara tax codes
