currently eat the fees, got to change that as they have gotten out of hand. dosen't really matter which processing co you use, (gone through a couple) . I am not a big shop and take just for convenience for my customers. Generally has been running about $50/mo. kinda a killer when you only have one customer use a card for $55. So I think I will have to start a minimum amount for cards like $200. Base fees are billed every month so it would be about $25 /mo with no one useing a card. Debit cards cost you more than a regular charge card. The processing fees vary a little depending who issued the card. You could add 3.5% to a credit sale for card use. That would offset some of it. Some states have a rule that you can't charge more for credit card use. WI used to, not sure if it is still on the books. Raising prices and giving a cash discount is a double edged sword, here we have to charge sales tax on the full amount before discounts or sale pricing- that is a pain as well. Only reason I got into it was of some of my customers are/were corporate accounts, A lot of that has dropped off over the last few years.
