Can the client manually add hours for the work done?

Question

Upwork

Hello, dear experts :) The
question has a little prehistory: Odesk: how to resolve the situation?
I completed the job, the client was satisfied. He noticed that I did not set the clock for my improvements and offered to pay for them, although I did not ask) For me, this is of course a pleasant surprise, and that's, in fact, the question. Can he add the hours that I spent on work or should I add them, and he will already agree in the system to pay them?

Answer 1

The client cannot add hours, he can only issue a cash bonus through odesk, it is clear that hours are more profitable, since many jobs have a limit of 100 or 1000 hours worked on odesk.
