My method for dealing with clients who want more than they paid for
I kept having clients ask for extra bits of work after we agreed on a price. It was eating up my time and I wasn't getting any more money for it. After one job where I did three rounds of free tweaks, I knew I had to fix this. Now, I write a very clear list of what my price covers before I start anything. I email this list to the client and make sure they say okay. When they later ask for something not on the list, I just refer back to our agreement. I tell them politely that it will need a new quote. This keeps things fair and has really cut down on those annoying requests.
