Project Billable Types: Hourly, Flat Fee, and Contingency

Choose the right billing model for each project and understand how it affects invoicing

How you bill a project determines how TimeTracker calculates invoice amounts. Choosing the right billable type upfront means your invoices will generate correctly without manual adjustments. Here's how each type works and when to use it.

Each project has a billable type that determines how work is invoiced.

Add New Project Dialog

The Add New Project dialog lets you set client, lead, billable type, and budget when creating a project.

Type
How It Works
Best For
Hourly
Tracked time × rate = invoice amount
Most client work where you bill by the hour
Flat Fee
A fixed price regardless of hours worked
Defined-scope projects with a set budget
Contingency
Billing depends on the outcome
Legal cases, performance-based work

Set the billable type on the Billing tab when creating or editing a project. The type affects how invoice amounts are calculated when you select entries for invoicing.
