How FreshBooks connects to Kintsugi
FreshBooks runs your invoicing. Kintsugi connects to your FreshBooks account and handles the tax, so you keep the invoicing setup you already have.

Connect FreshBooks
In Kintsugi, go to Settings, then Import, then Integrations, and choose FreshBooks. You sign in on FreshBooks' own screen and approve access. If your login owns more than one business, pick the one to connect.
Let the first sync finish
Kintsugi pulls in your clients, products and services, invoices, and credit notes. Set a start date if you want to limit how far back it goes.
Enable Tax Collection
Click Enable Tax Collection on the connection. Kintsugi sets up the link with FreshBooks for you, so there is no app to install.
What Kintsugi uses from each FreshBooks invoice

|---|---|
| Invoice line items | Classified for taxability and used to calculate tax |
| Client address | Used to find the jurisdiction and the rate |
| Sales Tax rate (returned to FreshBooks) | Written onto each taxable line. Lines with no tax are left untaxed. |
