Change Orders Generally, you’ll give your clients many freebies over the years. This is critical to good client-vendor relationships. They hook you up with being flexible about some aggressive deadline, and you are flexible with a word change here or there to the motion graphics. Here’s some boiler plate language you can use if the changes are significant: “Hi Client,  Thanks for your notes. This change is significant enough for us to evaluate additional hours. I expect it to cost an additional $X to $Y. Would you like to move forward with the changes?” Obviously, if timing is critical, make this a phone call . Be prepared with an estimate, or a range of costs. People don’t like when things cost more than they expected! Good luck…
