Businesses: do you allow CREDIT CARD payments?

[ironworks]

I do very few credit card transactions. I have found the guys who really can't afford to build a car try to use a credit cards. I have customers send me a check every 2 weeks for the work completed in that time frame. They send me a personal check and we start on another invoice. If at any point they are not satisfied they can pull the car or I can get rid of them. The additional expense of credit card charges for doing the transaction, is reason enough to me to not do a credit card transaction.

I understand some customers want the points or mileage for the large expense, but in the car building industry there is not the room in the hourly rate to lose another 2-3% on a regular basis. That margin could make the difference between a successful profit margin and not.
