I am a sole proprietor of a company where we provide development services. We had a contract in place that is signed by my former client that outlines payment terms and what we would be doing. We completed a project about 4 months ago and the client never paid our invoice. I have numerous emails and a recorded voicemail where they says the invoice will be paid but needs more time. I ended up suing them after getting the run around. I won the judgement in small claims court by default because he no-showed, however a few days later I got a notice in the mail that he had countersued. I have no idea what the reason is since I held up my end of the agreement and had no complaints from him while we were doing the work. If anybody could give me advice on what to do it would be appreciated.
