Blue Sky Project Tracker is a web-based time tracking system with expense tracking. The software is locally installed on a Windows server or PC. The web interface itself can be accessed with a web browser on multiple operation systems.In the web interface employees can enter the time spent on a project or sub-project. At the same time expenses can be entered. After a full week has been filled in the employee can submit the timesheet for approval by the manager. The time and expense tracking data can contain additional user data fields. These data fields can either contain text numerical values or items selected from a list. Examples of possible custom fields are: Client Notes and Payment method.Statistics are available in graphs and tables or can be exported to a spreadsheet file format. The statistics show for example the amount of time that has been spent per week on each of the major projects. Using a cost calculation factor the time spendings can be converted to a monetary value and combined with the other expenses.For each project a detailed description can be entered and the progress in percentages can be tracked. A permission system with user accounts user groups system permissions and project permissions allows fine-grained access control. For example a user or group can be permitted to view a project to comment on it to book spendings on it to update its progression or to completely manage it. The list of user accounts and their group membership can be imported from a CSV file.The Project Tracker Control Panel shows the status of the service and contains an option to check for an updated version online. The software can use or create a certificate to provide a secure HTTPS web interface.
