I didn;t know you delivered oil Carbon, I have a coal truck for sale. Includes a 1 week crash course in coal delivery.
Honestly I never had much trouble collecting, in about 6 years I had 3 bounced checks and two of them I believe were accidents because they rectified the situation immediately. I only got burned on the one check and that guy was in jail. I tried and work with them once they were established customer and offered credit with minimal interest charges. Worked out for me because I'd only have to go to the house once. Full loads = Big bucks.
