Classifying inventory is one of the most basic, yet essential and strategic parts of inventory management. Classifying inventory allows business owners to focus on items that make the most impact on their business goals while identifying (and potentially removing) items that aren’t contributing to the bottom line, selling or are obsolete.
Beyond simply identifying items as revenue-generating and dead weight, classifying items provides a better way to assign service levels to meet target fulfillment rates. The classification also simplifies the assignment of safety stock inventory (dollars of investment) to each item based on its contribution to the organization. Alignment of service levels to the various classifications of inventory will unite execution with strategic intent. This will mean happy customers and happy customers mean repeat business and recommendations.
Lastly, classifying inventory helps streamline your inventory management processes. With more predictability and less fires to put out, business owners can focus on the future rather than the now.

Classifying items as A,B, or C involves a few calculations to identify cutoff points and ends with identifying the 20% of your stock that produces 80% of your revenue, or margin. This helps business owners focus on the highest producing items, to ensure they are properly stocked. The problem with only classifying products using the A,B, or C method is that it doesn’t account for cheap items sold at a high rate. Including unit sales, or velocity, will ensure that these items don’t get improperly classified and cause issues with stock-outs.
