This is a serious question.. I want to know when it comes to push comes to shove.. what are the key features that you're looking for when you pick out a ecommerce. Now; Im not looking for everyone to say how great 1 cart and how it has everything. I'm looking for a feature list that's important to you guys.. who want to start a ecommerce shop or who have them already and realize you need something more.. tell me about it.
i'm in the field of ecommerce for 7 years, i can tell you that all the shopping carts out there doesn't have all the features you will need and if your site will start selling good you will need to improve it constantly, if you sale tangible good the most important is the stock control as most shopping carts have a very basic stock control system.
Most importantly, something that is easy to manage. I wouldn't want the admin panel to be too complicated, but at the same time I would want something that's got every feature imaginable.
I believe the biggest problem of e-commerce websites is high shopping cart abandonment rate due to complexity of checkout. You need to make checkout procedure very fast and easy not to give a chance to your customers to change their mind and quit. If you use Magento platform, GoMage LightCheckout can be very useful for you. It combines all checkout steps on one single page and allows enable, disable and sort fields easily from admin panel. http://www.gomage.com/extensions/lightcheckout.html
