The Linear solution features a Site Store with shopping cart functionality.
You are in control of product Main categories and Sub-categories. You define your shipping methods and costs. Virtually every aspect of the store/shopping experience is your to control. Best of all, it's fully e-commerce enabled through either Paypal, billing or Linear's secure credit card system.
Individual store items have small images and large images, short descriptions and extended descriptions. Withe each item you can define up to 2 attributes (i.e. size and color).
Your Web visitor is able to browse the categories (items can be placed in multiple categories). Click on an item and see the extended description. Click to add the item to the Shopping cart.
The internal management system will notify you of new orders. Quick reports show pending orders, fulfilled orders - even totals for individual store items.
Store Accounts: Want to get serious? Linear has a feature which can allow frequent shoppers to create an account for storing their shipping and billing information. With both shipping and billing the SUer can define multiple locations. Account Users may view past purchases and check on the status of current orders. Users may not edit existing orders - only review them.
The printable invoice is designed through your Linear system. (click for larger version)
Shopping Cart: Its full functioning - oh yeah. Shoppers can add items, view the cart and edit the contents. Once done shopping, the Web shopper simply clicks the "Check Out" link to enter their contact and shipping information. Redundancy will check the validity of their information. Depending on your configuration of the Linear system, shoppers will then either click to pay with a credit card or choose to be billed. Whichever, the system will provide the shopper with a confirmation number for order tracking - even the option of printing an invoice customized for your site.
