I have a client in the US who was happy and asked for a final invoice back in August 2019. He then stopped contacting me. Month by month we talked and he said there were PayPal problems, bank transfer problems, all kinds of problems. He said he would pay and was happy to. Stopped talking for a while then tells me he's ready. Basically, he's just playing around. I don't think I can take him to small claims court, but are there any actions I can take? Is there something I can email him so that he can understand the seriousness. When I mentioned lawyers, he got very worried so I think he wants to avoid anything like that. It's for around £500 so although not a lot of money, it's something I'd really like to deal with.
