What is SKU-Keeper?

SKU-Keeper is a hardware and software inventory management system. It’s designed from the ground up to modernize warehouse operations by leveraging the latest IIoT (Industrial-Internet-of-Things) technology. While it does some of the same things as traditional inventory management systems, WMS (Warehouse Management Systems) or ERP (Enterprise Resource Planning) systems, it’s far easier to use and way more economical–it even includes a whole Pick-To-Light system!

All Product Types

Search the master catalog of SKUs for all known types of products. The item may be in inventory or not.

All Areas

List or create areas of your warehouse. An area can be, for example, a storage aisle, shipping dock, receiving, QA: Set up your warehouse the way you work using names that are meaningful to you.

All Locations

Locations are places where inventory can be stored. Each Location belongs to an Area.

All Devices

Keep track of and maintain the Cloud Display Devices in your warehouse. Find and identify any device in just a couple of clicks!

All Picklists

View and assign Picklists to each Picker. Notice that total weight and dimensions are calculated!

All My Picklists

Privileges can be set so that Pickers can only see Picklists that are assigned to them. Pickers can start multiple Picklists at once to do batch picking. The resulting Task List aggregates everything in order for a single pass through the warehouse.

Completed Picks

All Restock Lists

View and assign Restock lists to Restockers. Again, dimensions and weights are totaled.

All My Restock Lists

Restockers can be limited to view only Restock operations that have been assigned to them. They can perform multiple Restocks together–batch Restocking!


Which Picklists can be completed given particular Areas of Inventory? Deficiencies shows how many items you’re short and how many to order.

“Voodoo Robotics pushes the envelope with their low cost SKU-Keeper warehouse inventory management system.  They’ve replaced the Software as a Service (SaaS) model with a leased Hardware as a Service model for warehouse picking and inventory management.  Voodoo’s proprietary “pick assist” modules are simple, reliable and easy-to-use.  These modules are connected to a robust web-hosted inventory management system and integrated with your smartphone or tablet.  Voodoo is years ahead of the competition.  People using this technology in their warehouses and distribution facilities will find the system reliable and inexpensive.  We like to call that a “no-brainer” decision around here.”
