See What Is In Progress and Unbilled

I am sure there is a lot of work we have done and never invoiced. Build me a work in progress app. Take approved billable time and any billable expenses that have not yet been included on an invoice, value them at the applicable rate, and show the total by client, by project and by person. Age the unbilled value into bands so I can see what has been sitting for weeks or months, since old unbilled time is far harder to bill successfully. Where work is being deliberately held back, require a reason to be recorded such as awaiting a milestone or a client agreement, so unexplained work in progress is visible separately. Add an AI agent that reviews the position and tells me what could be invoiced today and roughly how much that is worth, what is at risk of never being billed because of its age, and which clients or projects consistently accumulate unbilled time, which usually points to a billing process problem. Automate two things: a scheduled weekly work in progress report to me, and an alert when unbilled value for any client passes a threshold. Two logins: a project lead who sees their own projects, and an owner who sees everything.
