Depending on your employer's settings, the client you are working for may be able to approve your working hours after the assignment.

This works similarly to recording working hours:

As soon as an assignment is completed, you can record your working hours in the app and have them signed off by the client. To do this, use the "clock" icon in your assignment:

If the assignment is already over, scroll down in the app to "To Complete" and select "Send work data", which opens a view where you can see your past assignments.

As soon as the time editing screen opens by clicking on the clock icon, you can adjust the start and end times of the shift and the break times, and add a comment if needed.
Once you have entered your data, select "Approve work data":

This opens a form where the client can enter their company name, the signing contact person, and the email address, and then sign directly on your smartphone with their finger:

By clicking "Send", the working data approved by the client is sent directly to your employer and to the contact email address provided.

Depending on your employer's settings, it is also possible here to specify expenses or other costs incurred during the assignment.
