This is what Imploy uses to calculate the task’s main billable amount, and it’s also what enables you to mark a task as Billable.
To set the primary charge, open the task and use the Charge field in the task details (in the task header area). If the task doesn’t have a client selected yet, you’ll need to select the client first. Imploy won’t let you set a charge until the task is linked to a client.
Alternatively, the Primary Charge can also be assigned from the main task view. A 'Set Charge' button will also show there.
When you choose a charge, Imploy creates (or updates) the task’s primary finance entry in the background. The primary charge is tied to the task’s duration, so when you change the task duration, the primary charge updates with it.
If you try to tick Billable without a primary charge set, Imploy will stop you and prompt you to select a charge first. This prevents billable tasks from being created without enough information to bill correctly.
If your task already has multiple charges and you need a different one to be the main charge, open the task’s Finance tab and use Make Primary on the charge you want to promote (only saved charges can be made primary).
