Does Tryton have approval workflows for invoices and expenses?

Partly. The Purchase Requisition module lets employees raise requisitions that an Approval group approves or rejects before purchase requests are created. However, no configurable multi-level approval engine for supplier invoices or expenses is documented. No official upstream expense-reimbursement module exists, per the Tryton forum and the module list. Vergo adds optional approvals on spend before it posts into Tryton.

Where Vergo fits with Tryton

Vergo adds approvals on the spend before it reaches Tryton. Approval workflows are optional and fit how you already control spend: route by GL account or by amount — or skip approval flows entirely and let policy flags catch only what breaks a rule. Approved card spend posts into Tryton, coded to your account and analytic axes.
