I've just built a database for a client, she's received the database ahead of schedule, and is currently working on it, and has been invoiced (payment yet to be received).
Now I'm having to do further adjustments, for things that she would like to add.
Would you ask for more money for this? or would you agree to do the work for free?
I don't want to rock the boat since it's my one of few clients, but I do have money to make
How would you deal with this situation?
