Lenny ePassporte is the billing company, it's part of Paycom which also do Epoch.
You have to sign up to them before you can use your CC with them. They want you to use one CC, which they charge and you tell them what the charge amount was. This is to verify that you are the holder of that CC.
It's an excellent way to go for one off amounts B2B, this keeps the fraud and charge backs down so comission charges are low and no hold back. Which lets us know the buyer is solid and keeps our prices down.
We looked at most of the CC billing companies business models and they are useless for our type of business. Webmasters moan at getting a chargeback of $25-35, how would you feel about charge backs of $2,500-3,500. "A son cannot come onto our site and buy content and you charge it back." Well not through this system.
