I make custom items from metal, which involve machining, designing, etching, installing electronics, etc.
I was working with a client who I realized would be well served with a design I’d started on my own time.
Me: I have an incomplete design that could be modified to suit your needs.
Client: Will that knock the price down?
Me: No. most of what I’m charging for doesn’t change and besides, I should be paid for the design work I’ve already done.
Client: Will it make it any quicker?
Me: Maybe a little, but there is no real difference to you.
Lesson to me: don’t tell the client if you’re using previous work. Lesson to the client: DESIGN DOESN’T HAVE “DISCOUNTED FLOOR MODELS.”
