I see a lot of site with quick checkout workflow. You choose your product and you go directly to the checkout page to pay often without having to authenticate. In general, you receive an email when you have paid with instruction to create an account and/or provide your delivery address for physical goods.
I have some knowledge in Magento but I think I will have to break down this software if I want to build this kind of checkout workflow or something simple like that.
Do you have some recommendation about an open source (prerequisite) ecommerce solution in any language providing this kind of functionnality ? Or should I develop my own ?
Thanks in advance
