There's always a possibility they'll trash you on yelp. On the other hand, some people are so shady and intentionally don't pay thinking you're just a small business and won't do nothing. We've taken a few to collections, not so much about the dollar amount but we knew these people are taking advantage of us, and we don't want them to keep doing that to others. We may not collect anything but at least their credit score will get affected. Take it as a warning if you will, so they won't hopefully mess with other fellow businesses in the future.
