What is the Meaning of Inventory Management?
Inventory management is a function of business and operations management concerned with planning and controlling inventories.
Inventory management involves overseeing the stock levels of goods, from the point of purchase to the point of sale. It includes: Stock Monitoring, Demand Forecasting, Order Management, Supplier Management.
Intro to Inventory Management for Small Enterprises
In the heart of small business operations, especially in warehousing, lies inventory management. It’s an art and science of managing the journey of inventory from purchase to sale, ensuring you have the right stock at the right time.
The activities for inventory management varies from business to business based on the type of business and the products that are sold. For example, manufacturers will have a more complex inventory management process than a wholesale distributor because, typically, manufacturers manage and process raw goods before creating finished goods to sell to customers. In comparison, distributors primarily manage inventory of only Finished Goods and ship them direct to customers.
Broadly speaking, there are 9 inventory management activities used to manage inventory for small businesses. Not all activities are needed by every company and not all functions are done the same way at different companies. Inventory processes are tailored to fit business needs for each company.
1. Replenishment Planning
Replenishment Planning is a strategic approach to maintaining optimal inventory levels. It involves determining the right time and quantity for reordering stock to prevent shortages without overstocking. For example, a small boutique specializing in seasonal fashion must plan its inventory orders in line with changing fashion trends and seasons, ordering summer attire in spring to ensure availability when demand spikes.
Key Considerations:
