to all of my fellow contractors, how do I deal with Net 30 customers? I really can't afford to pass up the calls, since most of work is commercial work and their charges are much higher than residential. however, I have so much trouble getting these guys to pay their bills. local Hotels, Movie Theatres and Restaurants are usually pretty good, but most of the time Malls have these Service companies from all of the place they use and they won't pay me unless I hound the crap out of them. Any Ideas?
