Which of the following is not a role of the inventory management function not the inventory management process as a whole?

Entrepreneurs, founders, and independent brands now live in a native commerce world where small-to-medium businesses compete against global conglomerates.

We’ve put together this definitive guide to inventory management to level the playing field and help you grow your brand with speed, scalability, and smart insights. You’ll find everything you need from inventory control basics to best practices and formulas to advanced automation processes.

Inventory management definition

As a part of your supply chain, inventory management includes aspects such as controlling and overseeing purchases — from suppliers as well as customers — maintaining the storage of stock, controlling the amount of product for sale, and order fulfillment.

Naturally, your company’s precise inventory management meaning will vary based on the types of products you sell and the channels you sell them through. But as long as those basic ingredients are present, you’ll have a solid foundation to build upon.

Small-to-medium businesses (SMBs) often use Excel, Google Sheets, or other manual tools to keep track of inventory databases and make decisions about ordering.

However, knowing when to reorder, how much to order, where to store stock, and so on can quickly become a complicated process. As a result, many growing businesses graduate to an inventory management app, software, or system with capabilities beyond manual databases and formulas.

With these systems, the procedures of inventory management extend beyond basic reordering and stock monitoring to encompass everything from end-to-end production and business management to lead time and demand forecasting to metrics, reports, and even accounting.

Retail inventory management

Retail is the broadest catch-all term to describe business-to-consumer (B2C) selling. There are essentially two types of retail separated by how and where a sale takes place.

  • First, online retail (eCommerce) where the purchase takes place digitally.
  • Second, offline retail where the purchase is physical through a brick-and-mortar storefront or a salesperson.

Wholesale, on the other hand, refers to business-to-business (B2B) selling. Knowing the differences and best practices of retail and wholesale is critical to success.

Most businesses maintain stock across multiple channels as well as in multiple locations. The diversity of retail inventory management adds to its complexity and drives home its importance to your brand.

Importance of inventory management

For any goods-based businesses, the value of inventory cannot be overstated, which is why inventory management benefits your operational efficiency and longevity.

From SMBs to companies already using enterprise resource planning (ERP), without a smart approach, you’ll face an army of challenges, including blown-out costs, loss of profits, poor customer service, and even outright failure.

From a product perspective, the importance of inventory management lies in understanding what stock you have on hand, where it is in your warehouse(s), and how it’s coming in and out.

Clear visibility helps you:

  • Reduce costs
  • Optimize fulfillment
  • Provide better customer service
  • Prevent loss from theft, spoilage, and returns

In a broader context, inventory management also provides insights into your financial standing, customer behaviors and preferences, product and business opportunities, future trends, and more.

Inventory management formulas

If you’re new to inventory, you’ll probably come across a lot of formulas that might seem confusing at first. However, with a little bit of homework, these formulas can be very useful for keeping stock levels optimized.

Here’s an overview of some of the most common inventory formulas…

  1. Economic order quantity (EOQ) formula
  2. Days inventory outstanding (DIO) formula
  3. Reorder point formula
  4. Safety stock formula

1. Economic order quantity (EOQ) formula

Your EOQ is the optimum number of products you should purchase to minimize the total cost of ordering or holding stock. Figuring out your EOQ can potentially save you a significant amount of money.

EOQ = √(2DK / H), or the square root of (2 x D x K / H)

Where:

D = Setup or order costs (per order, generally includes shipping and handling)
K = Demand rate (quantity sold per year)
H = Holding or carrying costs (per year, per unit)
