FoxyPress

It will basically allow to use a FoxyCart like system shopping system inside the WordPress CMS.

Installation:

Unpack and upload it to the /wp-content/plugins/ directory.
Activate the plugin through the 'Plugins' menu in WordPress.

Features:

• Management/Back-end:
• Inventory Management. Manage your inventory from within WordPress. Add or edit item codes (SKU), names, descriptions, available dates, prices, categories, and images.
• Product Attribute Options. Apply product options, or option groups, to your inventory such as color and/or size. Multiple options may be applied to the same item.
• Product Pricing Options. Set different prices for different variations of the same product, such as $3 more for size XL.
• Product Categories. Organize products into categories (these will correspond to the categories you already have setup in FoxyCart), and assign items to multiple categories for cross-promotion.
• Transaction Syncing/Management. Sync your transactions with FoxyCart and manage transactions from WordPress.
• Transaction Statuses. Set your own "statuses" for transactions and make notes within them. Setting a product's status such as "Shipped" can also trigger an email to be sent to the customer with your own custom body or tracking number.
• Quick Inventory Add. Add inventory quickly with a downloadable Excel file that allows products to be added with no variations or options. Attributes can be defined once the inventory has been uploaded.
• Display/Front-end:
• Easy to Use. A simple WYSIWYG icon opens a dialogue box for adding products to WordPress pages.
• Display Inventory Items. Choose a single inventory item to display, or many.
• Display Options. Choose which products are displayed, how many appear, how many columns/rows are shown, and the detail page. Custom page templates can be used in conjunction with custom CSS to obtain the desired look and feel of the product listing and detail pages.
• Order Information Panel. Your customers can enter their transaction number to receive the current details of their order through the automatically generated order information panel.
• Search Inventory. Use the search option to quickly find the inventory item you're looking to post.
