When you're creating a budget, it is useful to add a time estimate that will tell you are you on track with delivering the service.
Only the project manager and the administrator can see the estimates, and they are also visible when logging time:
Using estimates will help you plan efficiently how much hours should you allocate to a a particular service. Don't worry if you go over the estimate with the hours logged, you can edit it at any time.
Tip: Clients can't see estimates anywhere in the app, unless it is a sales proposal that you will send to them as a document.
