I run a small business and would like to collect on a small bad debt a former client does not want to pay. It's $500, is a lien a better way to go?

The question

I run a small business and would like to collect on a small bad debt a former client does not want to pay. They're in WI, I'm in MI, it's approximately $500 and I see filing in the former clients county in a small claims court costs about $120. I understand I can also place a lien on the business(?), Would I have more luck with just placing a lien and taking my chances or is it always advisable to do the small-claims option and take my chances with a judge? Is there a better option?
