Big Commerce is an online e-commerce service – they provide the software and tech, you provide the products and manage your shop.
I established and designed the original theme for naturalinstinct.com and can honestly say that from a designers’ point of view, it was an OK experience.
Great reporting tools
The code is very modular and fairly well documented. Once you’ve worked out where all the numerous parts live, it’s not too hard to tweak things. I didn’t find support very responsive in regards to development issues but they were on the ball with shop owner issues.
I wrote a jQuery script for some additional menu functionality which seems to have helped a bunch of folks, but that was some time ago.
For a shop owner the tools available are pretty good with stock management, nice quality visual reporting, coupons as standard, you should check it out.
Woo Commerce is a WordPress plugin that adds sophisticated shop and cart functionality to any WordPress website.
It has been around for some time and with a very large user-base and developer following, there are many extensions and users to learn from.
Out of the box, it provides most shop store functionality and supports product variations, multiple shipping and payment gateways.
There is a pro version too that provides extra functionality.
The admin is excellent and the UI is really well implemented, lots and lots of hard work has gone in to perfecting this plugin.
