We are struggling to figure out appropriate pricing on real-time credit card processing. We are now resellers of Verisign Payment Services (formerly Signio).

I have been trying to figure out what others are charging for this service by browsing the directory at
http://webservices.cnet.com/html/aisles/E-commerce_Hosting.asp but it's frustrating because most of the listings either don't include real-time processing at all (just shopping carts), or the pricing for real-time
transactions is not included and is buried somewhere on the company website.

Any wisdom out there on this topic?

it's about USD$0.35 per approval real-time transaction on average! of course, plus another monthly charge, refound service charge as well.

Ibill has reasonable rates if you have a merchant account, and best of all, there is no monthly fee.
