or can I use Cs-cart with an Intuit Merchant Service for Web Stores account? I do not see it listed in the payment methods. I find something called QB Merchant Service in the gateway list, but nobody at Intuit can tell me if it is what I need to connect to their service. They ask me to confirm with my cart provider that it is compatible with QuickBooks SDK 4.1 or higher? I don't want to have to modify code to make it work.
