People working on a project track their time against services you defined in a budget. Tracking time you spend on a project enables you to have an insight in your project's profitability.
To see how much time is spent on what by who, open a budget and select Time entries tab.
You can view time entries by days, people and services.
Specify a time interval if you want to see time entries just for the last week or month.
If you want to see how many hours were spent on a specific service, select one from the dropdown menu.
When you're done defining all the criteria you're interested in, click on the green checkmark to run a report.
If you want to export time entries, click on the arrow and select PDF, XLS or CSV format.
You can edit or delete time entries. Sort time entries by days and select an option you need from a menu.
What is Client access for?
You turn Client access on when you want your client to have access to the project's time entries.
That way you don't need to export time sheets every month and send it to a client. You're giving your client a real-time insight into hours that were spent on a project.
What is Time approval for?
You set Time approval feature on if you want a person responsible for the project to take a look at time entries before they become visible to clients or any other internal reports.
To use Time approval feature you have to enable it first in the company settings. Read more about it here.
