We have been using CARTwebERP at ChasingTailSalsa.com for 6 months. It is the easiest shopping cart to install and there is nothing to maintain. Descriptions, pricing, pictures, and everything come from our accounting database. Whenever we change these things in our accounting system it is also changed on the web site. Our customers enter their orders directly into our accounting system through our Joomla web site. Nothing to synchronize. Payments are recorded too. All we have to do is show the merchandise is shipped and match the payment with the invoice. With webERP accounting system as the backend, it has the strongest back end of any shopping cart!
