Our client is an online book seller and didn’t want to use existing hosted carts or subscription based carts. We helped them to develop a custom shopping cart and developed modules to integrate with payment gateways and shipment providers.
Customers could sign up and checkout as guests or registered users and will be able to track orders. We also developed a backend system for their employees to add items/process orders etc..
