Managing, analyzing, and optimizing inventory is a never-ending job and often defines the success of a direct to consumer or B2B business. It’s arguably the most important thing to get right if you want your business to grow.
That’s why there are so many concepts around inventory you should understand. There are a lot of ways to look at inventory’s effects on operation and profitability. Let’s run through the big ones to flesh out the ripple effect inventory has across your business.
Inventory Meaning: What Does Inventory Mean?
Inventory, in business, is all the goods that a company owns, produces, and uses in service of production at any given time. It’s typically physical goods, though it can refer to services, like all work done prior to the sale. It’s usually a company’s largest current asset, or an asset expected to sell within the year.
That’s the general definition. And there are many types of inventory to consider within that definition.
But beyond that inventory meaning, there are a host of other related concepts whose definition will provide useful context to an understanding of inventory.
Let’s consider some.
Inventory Definition Accounting
Inventory is listed on a company’s balance sheet as an asset. That’s why the inventory definition from an accounting perspective takes into account the specific phases of production. Because inventory’s value is recorded and reconciled based on its place in the production pipeline.
Inventory, in that sense, is all the raw materials inventory, work in process inventory, and finished goods inventory that a company acquires and produces. Each of those types of manufacturing inventory can be recorded on the balance sheet separately. That’s why it’s a particularly apt inventory definition from an accounting angle.
Inventory Definition Economics
From a general economics perspective, inventory is all assets held by a business with the intention of selling in the market for profit.
Inventory levels and reactions to market consumption can have broad economic impact. If, for example, consumption of inventory in the market declines, any investment in inventory results in an accumulation of unsold goods.
Sitting inventory ties up cash and costs money to store. In large enough quantities—with enough decline in demand—inventory issues can cause widespread and substantial issues to entire industries.
Inventory Management Definition
Inventory management is the process of buying, storing, using, packaging, and shipping inventory. It covers the warehousing and processing of all goods that a business uses in production and produces.
A simple way to look at inventory management is as the balancing act between excess inventory and having to wait on an order (read more on backorder meaning) profitable items. This can be achieved by using the average inventory formula.
Shortages and excesses can indicate problems in inventory forecasting, production efficiency, and raw material acquisition. And they can have a big impact on a business’s bottom line. To thread the needle of optimal inventory operations, companies rely on inventory management to hit their inventory management KPI.
Inventory Turnover Definition
Inventory turnover is the ratio at which a company can turn goods into cash. It’s also called inventory turnover ratio, for obvious reasons. It’s an important factor when appraising a company’s financial health.
Why is that?
Well, the inventory turnover definition can be put another way. It’s how many times a company has sold and replaced their inventory over a specific period of time.
For most companies, this is their sole purpose. To create and sell a product. Inventory turnover, then, is a convenient metric that indicates just how good a company is at doing that.
Let’s say a coffee company’s monthly inventory turnover rate is 6 for their decaf blend. That means that over the course of a month, they sell and replace their entire decaf blend inventory 6 times.
Most companies end up with an inventory turnover rate of between 5 and 10. The higher the better.
Inventory turnover ratio is also called inventory turns. Any inventory turns definition will cover the same information above.
Inventory Control Definition
Inventory control is the regulation of the inventory a company has on-hand to ensure optimal inventory production. Tight inventory control means the right amount of safety stock to avoid overstock and shortages.
It differs from inventory management with respect to scope. Inventory control focuses on maintaining and adjusting inventory levels to ensure the most efficient production possible. Inventory management, on the other hand, is higher-level management of inventory. It includes which suppliers to work with, shipping routes, demand forecasting, etc. Inventory control is a part of inventory management.
Perpetual Inventory Definition
Perpetual inventory is a way to account for inventory that immediately records the purchase or sale of inventory. It then immediately adjusts the total inventory numbers accordingly. This is done with inventory management software that records all transactions and an inventory database that is adjusted based on those transactions.
In other words, it’s an inventory accounting method that happens automatically because software makes our lives easier.
As long as a company has inventory management software integrated into a POS system, every movement of inventory is recorded and cataloged in the database. Nothing enters the inventory pipeline without immediately being added to the database. And nothing exits without immediately being removed.
That way your inventory database always accurately reflects your current inventory levels and is adjusted in real time. And it can be done in your own facility or with vendor managed inventory.
A perpetual inventory system is opposed to a periodic inventory system. A periodic inventory system maintains records of its inventory by regularly scheduled physical counts of inventory.
Perpetual Inventory System Definition
A perpetual inventory system is opposed to a periodic inventory system. In a periodic inventory system a company tallies up their inventory stocks every once in a while. Or periodically. Then they compare a current number against a previous number to determine inventory change over time. They're also a vital form of eCommerce shipping software.
But in a perpetual inventory system, inventory levels are monitored in real time. And all inventory management and control decisions can be made at any time based on current, accurate numbers. Because those numbers are all updated perpetually, after every purchase and every sale.
