I'm looking for any sugestions on a shopping cart that has the ability to service my retail customers along with my wholesale accounts. I would need the customer to log in and only see thier price point. The group pricing has to have the ability to be able to plug in the prices, not a % off of retail. I am using Zen Cart now and thier group pricing only allows % off retail. Also it needs to be able to intergrate withh Quickbooks. I would be thrilled if I could find one that I could add fields to the log in (ex:tax #,date needed by, rep, ect. )

thanks for any help
