My revenue from my online business is getting lower over time and my credit card processing fees has approached 25% of my revenue. I am getting upset with all the fees the credit card companies and credit card processors impose on people. At some point I am thinking of dropping using my merchant account and just go with Paypal. I think my credit card processor charges for every attempt from my side to charge a credit card even if it's invalid. So basically someone at my online form can just sit and keep entering any card info and I get charged 40 cents for each attempt.
Does Paypal charge for successful transactions only?
