You send an estimate to a client for a 4 part project. It's an hourly arrangement and no guarantee of final cost is given.
The project ends up being much more involved than anticipated and you spend the entire budget of the estimate you gave completing 1 part of the 4. The client decides that is ok and doesn't really need the other 3 parts. Part 1, that you completed was the most important to them.
You bill for the time spent to complete the one part. The client balks at the charge and says that they should only have to pay 25% of the 4 part estimate since only 25% of the work was completed.
What do you do to solve the puzzle?
