Hey guys, I'm looking for a little bit of advice. I've designed a few websites for this particular client before and haven't had too much of a problem with him before. We agreed on him paying half of his payment before I give him the files and then once I receive his first payment I send my files over. Once that's done he sends his second half of the payment and everything is good to go. This time he hasn't followed through with his second payment and it has been two months. His reasons for not being able to pay usually have to do with something similar to: "I'm still waiting on my partner to pay me for the second half..." or "The site is going really slow and everyone is busy." I have now asked him to borrow money from his parents/friends/unicorns/whatever has money because this is getting out of hand. He responds to my emails within a day or two or sometimes not at all. What should I do? He is well aware that his payment is overdue and that he needs to follow through with his portion of the agreement.
