I like the honest approach and have an honest conversation with the client. They are not the easiest part of the job, but I can say that more than 80% of the time the client coughs up at least a little more money. Be as fair about is as you can….in other words you can say that the clients requests created about 8 additional hours of editing but you are asking for only half of your normal rate to do these cleanups… Most of the time they will bite on this. Most important is that they know how much beyond the original estimate things went…in hours and dollars.
If it comes to it, offer to have them pay the additional amount in 90-120 days…sometimes giving them a little more time can help make the “sale”.
Sometimes I let the client know when I DON’T charge them for changes. If it was a bad design, or clunky animation, or if I didn’t clean up the audio that was clearly bad, I tell them I fixed it and won’t bill them for the fixes. They appreciate this and will remember it.
I also will warn the client BEFORE I make their changes what it will take, how much it will add to the estimate. I just made this call today and got an additional $500 for making a bunch of changes that were the client’s last minute decisions, even though I had said I would stick to a number. They understood and paid it.
I like to keep communication going throughout the project so these things aren’t surprises at the end of the project.
Good luck.
