We work with a company calle Merchant Support. Yes we do. Miva Merchant is a browser based Storefront and Catalog development tool that integrates cataloging, product maintenance, category management, shopping basket, order and credit card processing. One central administrator can maintain multiple stores or specific store functions can be delegated to sub-administrators. The software is organized as a series of modules that can be field upgraded to provide new functionality without any changes to the core system.
Merchants manage their stores with a user friendly browser based interface.
Authorizenet is a service that provides real-time authorization and processing of credit card transactions over the internet. It's easy to set up and use and integrates easily with Miva Merchant. 1-Host can set you up with your own merchant account and Authorizenet service.
