Types Of Inventory Management

There are a number of types of inventory management that inventory managers use to ensure goods are available to meet customer demand. They include:

  • Stock review: This type of inventory management is usually particularly appealing for small businesses. It involves regularly analysing the goods that you have in stock versus what you project your future needs to be. While automated stock reviews can define a minimum stock level, this method requires regular inventory inspections.

  • Economic order quantity: Economic order quantity (EOQ), is a formula for the ideal amount of inventory a company needs to purchase and includes a set of variables such as demand rate, total costs of production and other factors. The purpose of the formula is to identify the greatest number of product units that need to be purchased to minimise buying.

  • Minimum order quantity: This type of inventory management applies specifically to suppliers and refers to the smallest amount of stock they are willing to sell. The retailer must be selling to purchase the minimum order quantity in order for the supplier to agree to the sale.

  • Safety stock inventory: With this method of inventory management, inventory manager order extra inventory beyond what the retailer expects demand to be. This technique is used to prevent out-of-stocks that are caused by unexpected changes in consumer demand.

  • Reorder point formula: This inventory management technique uses a company's purchase and sales cycles and may vary according to the product. With this formula, the reorder point is usually higher than the safety stock number, as it allows extra lead time for reordering.

  • FIFO and LIFO: FIFO stands for first in, first out and LIFO stands for last in, first out. With FIFO, they sell the older inventory first to keep the entire inventory as fresh and new as possible. LIFO is used to prevent the inventory from going back as they sell the newer inventory first.

  • Batch tracking: With this type of inventory management, the company groups and monitors stock with similar traits. This method is beneficial for tracking expired inventory or tracing defective products back to their original batches.

  • Bulk shipments: This method focuses on reducing the cost of shipping. With this, you palletise your inventory to ship more products at once.

  • Consignment inventory: With this type of inventory management, the vendor or wholesaler agrees to give the retailer their goods without an upfront payment. The vendor maintains ownership of the goods and the retailer pays for them when they sell.

  • Perpetual inventory management: This is the most basic type of inventory management technique and involves counting your inventory as soon as it reaches your warehouse. Inventory managers may manually record inventory in a spreadsheet or using pen and paper when using this technique.

  • Dropshipping: With this type of inventory management, the store does not keep the goods that it sells in stock. Instead, when a consumer purchases a product, the store purchases the item from a third party and has it shipped directly to the consumer. The retailer never handles the product directly.

  • Cross-docking: This is an inventory management method that involves inbound trucks unloading goods directly into outbound trucks. Using this technique, there is very little or even no storage between the deliveries.

  • Six Sigma: This is a methodology that focuses on improving the overall performance of businesses, increasing their profitability while decreasing the increase in excess inventory.

  • Lean Six Sigma: This methodology uses the tools of Six Sigma but focuses on improving the flow of business and increasing word standardisation.

  • Demand forecasting: With this technique, companies review historical sales data to determine an estimate for customer demand. In order words, the company estimates the number of goods that they expect customers to purchase and then uses this information to determine the amount of inventory they may order.

  • Lean manufacturing: This methodology specifically impacts a company's management practices. The goal of lean manufacturing is to eliminate waste and activities that do not add value.
