The timetracker allows you to enter the number of hours worked in a day.
It comes with an easy to use calendar where you click a date and a popup opens. There you can enter your hours and details about your work if required.
The interface offers a way to define the client you worked for and whether you worked from home (teleworked), went to the office, or went on site. If you used a mean of transportation, you can also select which one.
As the administrator you can then generate an invoice that you optionally make available publicly with the use of a key and automatically send by email to the client defined on that invoice.
