OS Commerce is very difficult to install and use – and it’s very limiting. There’s not enough features to run an entire professional business. The same goes with ZenCart. Magento almost has it right, but it’s also very difficult to install and it’s slow. You should look into a total online business platform such as www.haikuob.com which handles shopping cart, website, customer database and marketing features. It’s a hosted solution so you don’t have to worry about the technical stuff either. All the other bases are also integrated, such as the payment gateways, shipping modules etc., and you can even give your customers coupons and vouchers. It’s an all in one solution so you don’t need to juggle multiple systems.
