There are many distributors that have far more inventory than they care to have. Many of the companies that we talk with do not have a good inventory management system to control inventory levels. The systems being used are good, for the most part, for tracking current inventory and knowing current stock levels, but where many of the systems fall short is in the area of replenishing. Answers to questions such as when to buy, how much to buy, and how often to buy often rely on methods that are not accurate.
For accurate inventory levels, consider a system that has an inventory replenishment process that will not only take history into account, but will also consider other variables such seasonable items, shipping time, and vendor criteria (minimums or discounts).
