I need a custom shopping cart with shipping (UPS, FedEx and/or Canada Post) and payment integration (PayPal). It also needs to be connected to our existing MySQL database for sales/order history, inventory updates and customer management.
The shopping cart must have typical functionality including tax calculations (based on address), shipping/handling fees (based on address), discounts, user registration/access (guest checkouts allowed), payment/order confirmation as well as email notifications.
We sell new and refurbished computers, parts and accessories.
You may customize existing shopping cart software or develop from scratch, as long as a) all our needs are met, b) there are no ongoing software hosting/management fees, and c) the code may be modified/updated by us in the future without any copyright restrictions.
