When it comes to dealing small businesses, the last thing you want is for the company you’re working with to renege on a transaction after you’ve contributed your half. Sending multiple invoices may be enough to annoy them into submission, but if that doesn’t work the legal fees and time involved with taking them to court usually isn’t worth it. Cortera, a new site that launched yesterday at DEMO Fall, is looking to help businesses avoid this kind of dispute.

Cortera can be thought of as a Yelp for business credit, offering reviews on large and small businesses alike that have been submitted by the community. In other words, it can help you figure out if a company you’re thinking of dealing with is going to pay you in a timely fashion, or if it’s run by deadbeats who should be avoided.
