What is inventory accuracy?
Inventory accuracy refers to any inconsistencies between the actual quantity or type of physical inventory and what is recorded or is supposed to be. In most cases, it is the difference between what’s recorded in an inventory management system and what you have available for sale in a store, warehouse, or storage location.
Importance of inventory accuracy
Inaccurate inventory is obviously problematic as it can translate to incorrect customer orders, a shortage of product, theft, damages, loss for your business, or even trouble selling through what you have before it becomes obsolete.
But there are also implications on the accounting side that can cause more trouble for a business.
For example, inaccurate inventory can lead to inventory shrinkage when stock is less than the recorded balance in accounting records and can throw off your inventory valuation at the end of a financial year or accounting phase.
By making sure your inventory is accounted for, your operations run more smoothly and you make more sales. Here are some of the reasons why maintaining inventory accuracy is so important.
Minimize customer loss
Having inventory inaccuracies is troublesome because it can translate to incorrect customer orders because you have a shortage of product. This can be a loss for your business as a result, or you may even have trouble selling through the inventory you have before it becomes obsolete.
When your inventory is accurate, you ensure customers are getting what they ordered instead of turning to your competitor.
Reduce operational and holding costs
If you don’t have a clear understanding of how much inventory you have, you may buy more inventory than you need. When you have a surplus of inventory that isn’t selling, it is sitting on the warehouse shelf racking up holding costs. Knowing when to move those items helps you drive down operational costs.
Prevent inventory shrinkage
When you have accurate inventory counts, you’re able to monitor how much product you have. If you have inaccuracies in your inventory records, you can experience inventory shrinkage. Inventory can easily go missing due to theft, damage, or pick errors.
Keep inventory valuation in check
If you experience inventory inaccuracies, it can throw off your inventory valuation at the end of a financial year or accounting phase. Making sure you have proper inventory results in less headaches for you and your finance team.
Why ecommerce shops struggle with inventory accuracy
Achieving inventory accuracy isn’t an easy task, but it can be made easier with the right technology, processes, and know-how. Here are the most common reasons why inventory accuracy is challenging for ecommerce brands.
They are self-storing
Many ecommerce stores prefer to be as independent and cost-effective as possible, and usually self-fulfill and self-store their products from their home. This can lead to inventory accuracy problems when it’s not being stored professionally or managed in a warehouse.
And as the business grows and expands its product line, inventory storage only becomes more difficult without the right equipment and a dedicated, experienced team.
Their inventory management system is sub-par
If your inventory management system is basic or non-existent, you may be tracking inventory on paper, spreadsheets, or not at all. Having integrated technology helps keep inventory records up-to-date, making things easier for accounting purposes, helping prevent stockouts, and streamlining purchasing from manufacturers.
“So many 3PLs have either bad or no front-facing software, making it impossible to keep track of what’s leaving or entering the warehouse.
On the supply chain side, I just throw in what we placed at the factory into a WRO in the ShipBob dashboard, and I can see how many units we have on-hand, what’s incoming, what’s at docks, and so on. I can see all of those numbers in a few seconds, and it makes life so much easier.”
Harley Abrams, Operations Manager of SuperSpeed Golf, LLC
If you introduce new sales channels, multichannel inventory management is needed to prevent over-stocking and under-stocking issues across stores.
How to calculate inventory accuracy
There are two common methods for calculating inventory accuracy.
1. Physical inventory counting
Inventory reconciliation, or the process of comparing physical inventory counts with records of inventory on hand, helps reduce stock discrepancies and understand why there are discrepancies in the first place.
You’ll need to perform a physical count of all the available inventory on hand and compare it against what you’re supposed to have.
You can use this formula to calculate inventory accuracy rate:
Inventory Accuracy Rate = (Counted Units / Units on Record) x 100
If the two counts match up, then your inventory is accurate and does not have any inconsistencies. If it does not match, then there is an obvious discrepancy.
The best way to get the most out of this method is to perform weekly checks using this method. This way, you can progressively keep track of your inventory.
2. Inventory valuation
This method for calculating inventory accuracy is an inventory accounting practice and is done by counting the value of the inventory you have on hand (physical inventory), and then dividing it by the value of the inventory you are supposed to have in whatever you use to track inventory data. This method is not as accurate, as you are not comparing each item in your inventory.
If your inventory accuracy is low, you should consult your sales receipts and records. This could reveal the discrepancy (e.g., you may have sold the missing inventory).
What is the average inventory accuracy?
It is almost impossible to retain a 100% inventory accuracy rate, no matter what calculation method and technology you employ but it shouldn’t be too far from it. Typically, the average inventory accuracy is 99.6%, where the 0.4% is mostly due to human error that is inevitable for large companies. The more transactions you have, the higher the probability of a discrepancy in inventory data, and the occasional mishap isn’t something to worry much about.
7 tips to improve your inventory accuracy
After choosing an inventory accuracy calculation method and computing your inventory accuracy, you might feel that there’s room to improve your inventory control. Here are some tried-and-tested methods for improving inventory accuracy.
1. Count your inventory regularly
Inventory accuracy is a metric that should be top of mind. Inventory should be checked often to make sure your physical inventory matches your records. By doing this regularly, you’ll minimize the chance that your inventory is incorrect. And if your inventory is inaccurate for any reason, you’ll be able to fix the issue early on.
2. Adopt the cycle count program
Cycle counting is a way of managing inventory where a portion of inventory is counted in specific locations, on certain days, on a recurring schedule. Implementing a cycle count program allows you to forgo annual physical counts so you can count specific items on a more regular basis and therefore ensure your inventory is accurate.
3. Improve inventory security
Having proper inventory security ensures the safety of your products in the storage facility. By making sure your inventory is secure, you’re able to minimize theft. As a result, your inventory counts will remain accurate since theft is not a consideration.
4. Use more professional storage methods
Instead of self-storing your inventory, consider professionally storing your inventory in a proper warehouse. It’s all too easy to lose inventory in your apartment, basement, garage, or car.
Although an investment of this kind might incur higher overhead costs, you may end up saving money, in the long run, thanks to greater inventory accuracy. Of course, a good warehouse is not enough though; Proper warehouse management will help you keep tabs on real-time inventory records.
5. Work with a fulfillment partner
Rather than storing your own inventory at all, you can pair up with an ecommerce fulfillment partner that can store your inventory in its their warehouse(s) and manage it for you. Fulfillment companies specialize in picking, packing, kitting, shipping, inventory management, and warehousing.
“We have a Shopify store but do not use Shopify to track inventory. In terms of tracking inventory, we use ShipBob for everything — to be able to track each bottle of perfume, what we have left, and what we’ve shipped, while getting a lot more information on each order.”
Ines Guien, Vice President of Operations at Dossier
6. Upgrade your inventory management system
Having a reliable inventory management system is necessary to help your business scale sustainably. If your inventory management system is too basic or lacking the features you need, your inventory accuracy could be suffering. In this case, you should consider investing in a better, more connected inventory management system or ERP system.
“Another ShipBob integration I love is Inventory Planner. It saves me hours every week in Excel spreadsheets, and I can raise a PO in minutes when it used to take me hours.
For every order I placed for years, I was ordering too much or not enough. Between inventory forecasting tools and the ability to auto-create WROs, we don’t have stockouts much anymore. I sleep better at night.”
Wes Brown, Head of Operations at Black Claw LLC
You can also look to use hardware and other equipment like inventory scanners to improve inventory processes within your warehouse.
7. Run frequent and randomized inventory checks
One way to improve your inventory accuracy and save time is by scheduling a frequent cycle count. A cycle counting program is an inventory auditing procedure, and conducting these frequently can prevent unchecked inventory from piling up, keeping your records consistent, and minimizing potential inventory error.
