New e-commerce shopping cart and order management system

NEW E-cOMMERCE SHOPPING CART AND ORDER MANAGEMENT SYSTEM

Seeking configuration support for a new e-commerce site.

Currently using volusion but happy to move to another shopping cart if required.

Looking for a shopping cart that is integrated and has single order management and inventory management for two website, ebay, amazon, facebook and others that may be needed in the future.

Currently, Linnworks appears to offer this kind of solution, but support required to configure and set up Linnworks with a compatible shopping cart (assuming volusion is not compatible).

The shopping cart needs to be modern looking (so OS COmmerce may not be the answer) and have all usual features of a good cart. Most likely using x-cart, zencart, cube-cart etc (these are the linnworks compatible carts).


The centralised order management systems needs to have:
- single location for managing all orders
- single location for managing, updating and changing inventory levels
- all basic functionality for order management without having to separately go into my website, ebay or amazon websites



Looking to start ASAP.
