A key part of running an Amazon business is inventory management. It will help you avoid two major profit killers: loss of sales due to stock shortages and expensive storage fees due to overstocking.

The key to good inventory management is finding the right balance between too much and too little stock. You can determine how often to reorder inventory to maintain optimal levels of stock if you have the right strategies.

Why is inventory management important?

Customers don’t have the patience to deal with poor inventory management. Customers expect speed and convenience when shopping online. 68% of U.S. customers expect items to arrive within two to three days after purchase. 47% will pay more for faster shipping. Online shoppers don’t want to wait for their products to be back in stock. 70% of them would be disappointed if they received their order late.

Your customers will be forced to buy from your competition if you have insufficient inventory. This can increase your organic ranking and decrease yours. If you have too much inventory, your business will be tied down and you may face long-term storage fees.

Many factors can affect Amazon seller’s inventory management: the manufacturing and shipping times of your supplier, customs delays and FBA storage capacities and fees, as well as the sell-through rate, all play a part.

It can be hard to determine how much inventory you should order when you launch your first product on Amazon. Your brand-new listing won’t have any reviews and it won’t convert nearly as well as the listings of your competitors.

You will eventually learn how quickly your inventory sells so that you can order more accurately to avoid selling out or overstock.

Common inventory issues Amazon sellers face

Inventory problems are something that most sellers will encounter at some point in their lives. It’s important to be ready to deal with any issues that may arise.

Running out of inventory

Don’t sell out of stock. It will hurt your Amazon Best Seller Rank. If you are running out of stock and waiting for shipments, a great way to keep your inventory in stock is to slow down the demand side. This can be done by putting a halt to marketing strategies like off-channel campaigns or ads, as well as setting a higher price for your product. This will allow brands to retain existing customers, while slowing down the acquisition of new customers.

Avoiding stock outage is your goal, even if it means slowing sales and advertising less.

Your Best Sellers Rank (or organic keyword ranking) will suffer more damage if you’re out of stock for longer periods. Amazon only promotes products that are always available. You may lose your ranking if your products aren’t available consistently.

Overstocking inventory

You don’t want your inventory to be depleted, but you also don’t want to stockpile too many products. If you use FBA, this can lead to you spending more money on inventory than you would otherwise need to replenish faster-selling products.

Amazon will consider your excess inventory if the product is out of stock for more than 90 days and/or has at least one unit older than 90 days. Amazon is not a fulfillment center, but a storage facility. They expect products to be moved in and out in 90 days. The quicker, the better.

Your overall IPI score (inventory performance indicator) will be affected if you have too much inventory. If you have too many inventory in Amazon fulfillment centers, they will decrease your inventory storage limit and charge you monthly storage fees. These costs can add up, sometimes even exceeding the actual value of your unsold inventory.

Seller Central provides tools that will help you identify excess inventory in FBA and address long-term seller fees.

FBM (fulfillment through Merchant) can cause your money to be held in slow-moving inventory, even if you use it. You could also be paying storage fees if you use a third-party fulfillment center.

Stranded inventory

Many sellers aren’t familiar with how to deal with stranded inventory. It happens when inventory in Amazon’s warehouse doesn’t have an active listing. It is basically in limbo — it is still available for sale, but it cannot be purchased by customers.

The worst thing about stranded inventory? Even if your products aren’t listed for sale, you will still have to pay monthly storage fees per unit.

Amazon will display inventory that is currently stranded in your Inventory Dashboard. This section is not subject to Amazon alerts, so you need to check it regularly.

Long-term storage fees

Let’s get back to the subject of excess inventory at an Amazon fulfillment center. This is another problem you should avoid. Amazon can charge you a lot depending on how long-term you store your inventory.

Amazon evaluates its entire fulfillment network every 15th of each calendar month to determine the age of all sellers’ stored inventory. The date your inventory arrives at FBA warehouses is the start of its age. Long-term storage fees will apply to inventory that is kept for longer than one year. These fees are in addition to the normal monthly storage fees.

Amazon states: “Inventory that has been in a fulfillment center for more than 365 days will be charged a monthly long-term storage fee of $6.90 per cubic foot or $0.15 per unit, whichever is greater.”
