Inventory Management

As the cost of logistics increases retailers and manufacturers are looking to inventory management as a way to control costs. Inventory is a term used to describe unsold goods held for sale or raw materials awaiting manufacture. These items may be on the shelves of a store, in the backroom or in a warehouse miles away from the point of sale. In the case of manufacturing, they are typically kept at the factory. Any goods needed to keep things running beyond the next few hours are considered inventory.

What is Inventory Management?

Inventory management simply means the methods you use to organize, store and replace inventory, to keep an adequate supply of goods while minimizing costs.  Each location where goods are kept will require different methods of inventory management. Keeping an inventory, or stock of goods, is a necessity in retail. Customers often prefer to physically touch what they are considering purchasing, so you must have items on hand. In addition, most customers prefer to have it now, rather than wait for something to be ordered from a distributor. In manufacturing, inventory management is event more important to keep production running. Every minute that is spent down because the supply of raw materials was interrupted costs the company unplanned expenses.

Counting Current Stock

All businesses must know what they have on hand and evaluate stock levels with respect to current and forecasted demands. You must know what you have in stock to ensure you can meet the demands of customers and production and to be sure you are ordering enough stock in the future. Counting is also important because it is the only way you will know if there is a problem with theft occurring at some point in the supply chain. When you become aware of such problems you can take steps to eliminate them.

Managing Small Items

Businesses that use large quantities of small items often use an “80/20” or ABC rule in which they keep track of 20 percent of the largest value inventory items and use it to represent the whole. “A” items are the top valued 20 percent of the company’s inventory, both in terms of the cost of the item and the need for the item in the manufacturing or sales process. Controlling this top 20 percent will control 80 percent of their inventory costs. “B” items are those of mid-range value and “C” items are cheap and rarely in demand.

The retailer or manufacturer can now categorize all items in the inventory into one of these three classes and then monitor the stock according to value. “A” items would be counted and tracked regularly, while “B” and “C” items would be counted only monthly or quarterly.

Cyclical Counting

Many companies prefer to count inventory on a cyclical basis to avoid the need for shutting down operations while stock is counted. This means that a particular section of the warehouse or plant is counted at particular times, rather than counting all inventory at once. In this way, the company takes a physical count of inventory, but never counts the entire inventory at once. While this method may be less accurate than counting the whole, it is much more cost effective.

Controlling Supply and Demand

Whenever possible, obtain a commitment from a customer for a purchase. In this way, you ensure that the items you order will not take space in your inventory for long. When this is not possible, you may be able to share responsibility for the cost of carrying goods with the salesperson, to ensure that an order placed actually results in a sale. You can also keep a list of goods that can easily be sold to another party, should a customer cancel. Such goods can be ordered without prior approval.

Approval procedures should be arranged around several factors. You should set minimum and maximum quantities which your buyers can order without prior approval. This ensures that you are maximizing any volume discounts available through your vendors and preventing over-ordering of stock. It is also important to require pre-approval on goods with a high carrying cost.

Keeping Accurate Records

Any time items arrive at or leave a warehouse, accurate paperwork should be kept, itemizing the goods. When inventory arrives, this is when you will find breakage or loss on the goods you ordered. Inventory leaving your warehouse must be counted to prevent loss between the warehouse and the point of sale. Even samples should be recorded, making the salesperson responsible for the goods until they are returned to the storage facility. Records should be processed quickly, at least in the same day that the withdrawal of stock occurred.

Managing Employees

Buyers are the employees who make stock purchases for your company. Reward systems should be set in place that encourage high levels of customer service and return on investment for the product lines the buyer manages.

Warehouse employees should be educated on the costs of improper inventory management. Be sure they understand that the lower your profit margin, the more sales must be generated to make up for the lost goods. Incentive programs can help employees keep this in perspective. When they see a difference in their paychecks from poor inventory management, they are more likely to take precautions to prevent shrinkage.

Each stock item in your warehouse or back room should have its own procedures for replenishing the supply. Find the best suppliers and storage location for each and record this information in official procedures that can easily be accessed by your employees.

Inventory management should be a part of your overall strategic business plan. As the business climate evolves towards a green economy, businesses are looking for ways to leverage this trend as part of the “big picture”. This can mean reevaluating your supply chain and choosing products that are environmentally sound. It can also mean putting in place recycling procedures for packaging or other materials. In this way, inventory management is more than a means to control costs; it becomes a way to promote your business.
