A long-time client wanted to start a new project. I scoped it out with him and gave him a quote of $1,000. He approved.
I presented the work to him.
Client: Can you make these changes?
Me: Those are significant changes that are basically another new project. They will cost $750.
I delivered again, and he made requests for changes. This time they were minor so I charged an additional $150.
I sent him the invoice.
Client: (furious) What is this? You told me the project would be $750!
Me: What? No. I told you it would be $1000, with additional charges.
Client: No, you said $1000, and then when I wanted changes you lowered the price to $750.
Me: So you think when faced with doing more work I LOWERED the fee?
Client: Well what you did definitely isn’t worth $1900.
