Hay many people use collections agencies to try and recoup unpaid debts, both personally and in business.

know a gal that does it on the corporate level and most of the time they don't even know they owe the money.. they go back to accounting and review the amount.. just to find out it just fell through the cracks.. i think she make good money doing that too..

My mother use to do it. She said there are 100's of in's and out's when trying to collect
