For Time and Materials billing type services, you can define a fixed cap that limits the maximum amount billed to the client, regardless of how many hours or expenses are logged.
Setting a Maximum Charge
In the Budget editor, set the service billing type to Time & Materials, and define its price and quantity.
Open the fields menu and select Show fixed cap.
A padlock icon will appear beside the Time & Materials service line items.
Click the padlock to activate it (it turns violet). This ensures the client cannot be charged more than the defined total.
Save changes to confirm the setup.
Once saved, the Fixed Cap Enabled field (Yes/No) will be available, letting you easily check whether a cap has been applied.
