A buyer contacted me to get a keynote prepared. I designed it to meet his specifications that he had mentioned under Order Requirements and delivered one full day before the deadline. After two days he requested for a modification saying he wants it designed in a totally different way, which he had not specified in the first place.
Do I charge additional, taking it as a new project or do the “modification” at no cost? What if he changes his mind again? How do I deal with such situations/buyers?
Please help. Thanks in advance!
