Our goal is to make sure our client's achieve their inventory and service objectives

At Inventory Worx, we combine our team's vast supply chain planning and business process knowledge with industry best practices, technical expertise, and a client-first focus. We target the areas of the planning process that are often the most challenging to execute because they can drive significant business value in reducing inventory, increasing service levels, and improving productivity.

Customer success has always been of the utmost importance to us when engaging with a client on any type of sales effort or project. When we founded Inventory Worx in 2015, we had one goal in mind...we wanted to create a services organization where success was measured by customer happiness and retention - not by margin.  All of us at Inventory Worx not only understand this goal but live by it.  We know what is needed to start a project and finish it successfully.  Our homegrown methodologies, which will forever continue to evolve, address all aspects and challenges of delivering successful outcomes to our clients. With a combined-experience pool of 30 years in inventory and demand planning, we are confident we can ensure your projects are completed successfully.
