What is Inventory Control? Explained in 9 minutes

Summary

Inventory control is a crucial process that ensures businesses maintain the right stock levels to meet demand without overspending. It involves monitoring the flow of goods, minimizing losses, and optimizing stock to reduce costs. Through techniques like Just in Time (JIT), Economic Order Quantity (EOQ), and real-time tracking, companies can improve efficiency. From retailers like Walmart to e-commerce giants like Amazon, effective inventory control helps businesses prevent stockouts, reduce waste, and increase customer satisfaction. Mastering inventory control is essential for building a smarter, more reliable business.
