Personally I dont charge for any enhancements, everything is included for a fixed fee. Thats how my suppliers work and thats how I work with my clients. I wouldnt be in business too long if I quoted one price and charged another. As long as you are adding value you will not get stung.

You need to look at your requirements engineering, and pricing processes and make them more agile. It sounds like ypou jump too quickly from requirements to implementation without doing scoping and boundary properly, or maybe not seeing the actual business value in the solution - if you see this you will pre-emp the changes to spec

Have a look at this
[agilemanifesto.org...]

If you are doing big projects then it wont work maybe something like Prince2 will help instead.
