Can I set a price for a task if I'm billing by the hour, day, or week?

Yes!

When adding a task, click the clock icon in the popup. This will unveil a price field.

You can either leave the hour estimate blank (for things like buying stock art or something that you don't care about tracking time with), but you can also set an hourly estimate. If a price is set, we don't apply your rate to the task — a task with a price of $500 will be billed at $500, regardless of whether 10 minutes or 10 hours of time is logged against it.

We encourage you to set time estimates, even if the task has a set price, as it helps you understand how profitable that requirement was, and helps us accurately gauge your project progress.
