We are an international IT company and expect strong growth. This is one of the reasons why we are looking for a professional time tracking system.
The software should meet the following requirements:
- Accurate time tracking for currently approx. 35 users
 
- Time allocation by project/task/category/cost center
 
- Real-time evaluation functions for the recorded times
 
- Costs/user, total costs
 
- Appointment calendar
 
- Vacation requests and approvals
 
- Support for international travel (sales tax, multiple currencies and languages, German/English also user-specific, e.g., Euro/USD...)
 
- Recording of receipts, etc. from mobile devices, including mobile travel expense recording
 
- The effort required for tracking should be kept to a minimum and run almost automatically, so that manual re-entry at the end of the month or similar is avoided and the accuracy of the recorded times is kept as high as possible
 
- Contemporary look
 
- Preferably with an interface to PM software (JIRA, Redmine, Github) to automatically record tasks/tickets, and also to MS Excel
 
- Desktop and mobile apps would be useful, as would a web browser – web-based preferred
 
- Possibly also a desktop widget or monitor tracking
 
- Integration with GoTo, JIRA, SugarCRM, Google Calendar, Redmine, Github, Atlassian, Zapier(?)
 
Maintenance should be kept to a minimum, e.g. through automatic updates, etc. The software should currently manage approx. 35 users. However, administration should be carried out by a small number of users.
