If your store sells variations of products on the same page in your Zen Cart store, you will need a way to accurately manage the inventory of each variation separately. Whether your variations differ by size, color, material, or any other attribute, the Numinix Product Variant Inventory Manager (NPVIM) will provide you with a simple and easy-to-use interface for managing your stock.

  • Intuitive interface
  • Uses AJAX to avoid page reloads 
  • Track inventory of product variants (attribute combinations)
  • Show available stock on selection of variants on the product info page
  • Dynamically display attributes from available variants as selections are made on the product info page
  • Hide out of stock options on the product info page
  • Convert/migrate inventory from Stock by Attributes
  • Add data to variants (i.e. UPC, ISBN, SKU codes)
  • Supported by Ajax Shopping Cart with Coupons, Fast and Easy Checkout, Fast and Easy Ajax Checkout, and One Page Responsive Checkout
  • Supports all default Zen Cart stock settings

The package includes documentation for easy modification of the catalog and core files to support variant stock. We've also included a script for converting your existing Stock by Attributes (third party Zen Cart mod used for tracking stock of attributes) to our system. Unlike Stock by Attributes, our tool uses a more logical table structure which is both faster and easier to support by other third part plugins (Linnwords, for example, is a third party inventory manager that works across platforms and can use our table structure to sync inventory with eBay and other ecommerce platforms that your store may share inventory with).

    Just what I needed!

    This mod was exactly what I was looking for as I couldn't get 'Stock by Attribute' to work with the newest update of ZenCart. I also love the added features- like the Dynamic Attributes compared to 'Stock by Attribute'. I wish there was a bulk feature but other than that small flaw it works 100%, kind of a pain to do each product one at a time and as long as you don't have too many attributes it goes pretty quick. They installed this mod without issue, and I will use them to install future mods.

    The Business, Excellent Tool

    This is no doubt one of the best purchases from yourselves, we had another version of this from CEON which had so many bugs and not updated. The Numinix Variants Inventory Manager is far superior and is actually really simple to use. Love it. couldn't be with out it. Thanks (-:

    Best solution for attributes

    This has been very powerful software to help us, and it is very efficient and has lots of flexibility.

    NPVIM an essential tool for Zen

    One of the weaknesses of the basic Zen Cart application is the ability to quickly and easily manage the inventory values of products that use atttributes or variants. Base Zen Cart functionality was not adequate. The Numinix Product Variants Inventory Manager was just what we needed. This enhanced inventory manager allows us to navigate and update inventory with ease. If you use products with variants, this module is an absolute must. The only caveat is that installation of this module will significantly change the database structure. You must be careful if you are using any 3rd party software to access the MySQL database.
