Odoo FreshBooks Integration

FreshBooks is cloud accounting aimed at small service businesses and freelancers, strong on invoicing and expense tracking.

An Odoo to FreshBooks integration suits a service business that has grown into Odoo for operations but whose accountant still works in FreshBooks. The integration keeps invoices, expenses and payments consistent across both.

The integration uses the FreshBooks API with OAuth.

• Odoo to FreshBooks: invoices, payments and clients.
• FreshBooks to Odoo: optionally expenses and payment status.

• Two ledgers. Decide authority per record type.
• Scope differences. FreshBooks is lighter than full double-entry accounting, so not every Odoo transaction has a clean FreshBooks equivalent.
• Client matching. Clients need a matching rule to avoid duplicates.
• Token refresh. OAuth tokens expire and need refreshing.
• Tax handling. Tax treatment must align between the systems.

1. Create a FreshBooks API client and complete OAuth.
2. Agree authority per record type and what syncs.
3. Map clients, tax and payment methods.
4. Run a pilot period and reconcile.
5. Schedule the sync.
6. Monitor token refresh.
