I'm trying to decide what is the right course of action about a non-paying client while remaining tactful. FYI, I am a 19 year old web designer (freelance, just recently became incorporated, etc.) I did a web site for free for some really good friends of mine. As a way to thank me, they have recommended me to a ton of people and brough in a lot of business for me. One of the sites I did was for one of their really good friends. I now ask my clients for deposits, but I didn't ask him for a deposit but did tell him payment was payment upon completion of the site. The site took about a month to build and was fully launched in early July, and he was very happy. I billed him towards the end of July and the invoice said payment was due within 2 weeks. I hadn't gotten anything from him, so after about 4 weeks, I emailed him and said to mail the check to a different address, as I was going back to college. No response. Emailed him again about 10 days later, no response. Called him about a week later and he said was going to pay me, and that he had gotten my emails. Still no check. He then had the audacity to email me and ask him to change something on his site for me. I emailed him and said I would happy to make the change, but that I could not move forward until I was paid for the site. That was about 4 days ago, and I haven't heard from him, and I know he is getting my emails. I didn't want to "harrass" him since he is really good friends with my friends, but this is ridiculous. Is it appropriate to take his web site offline at this point? It has been about 6 weeks since he was supposed to pay me.
