what i need is a simple system for the client to request work with billing calculation.
the client adds a task to a task list
i price the task (each task)
then the client accepts the task
then i do it.
at the end of the task i mark the task done
then i want to see a summery of the bill of my client for each month.
i have many clients and also i have two large clients. i am a subcontractor for them.
i record how match each client of my large client have to pay.
so i divide the bill.
i need some permissions i want the client could not be able to change the work that it is accepted by him and just comment on it.
time spent is related to a task.
it is bad for me to do work without the client know how match he will pay at the end.
i must tell hit before i begin to work.
