Built In Project Management Software

需求

It would be nice to have a built in project management system. Even as an add-on product that has a one time cost. I would like to see features such as: - Ticket integration - Attach files - Attach to customer or set for internal use - Reporting ability - Create tasks - Each person who works on tasks can add their time per task for billing - Allow for customer to see project or not - Billing integrations - Ability to bill a whole cost or by the hours spent - Ability to choose what hours to bill for and what not to that was entered - Tasks status - Project status and ECD - Milestones - Ability to create templates for projects so all tasks do not have to be created for new project if one has been done in the past just like it - Note section - Communication board for collaboration
