An Essential Guide To Ecommerce Inventory Management

an-essential-guide-to-ecommerce-inventory-management

Creating an ecommerce inventory management system allows you to bid farewell to issues such as overstocking or overselling.

Ecommerce inventory management often seems simple: Make sure you have enough products to meet demand without overstocking, and you’re good to go — right? Not quite.

In reality, striking this balance is challenging. According to the U.S. Census Bureau, U.S. retailers sit on $1.26 of inventory for every $1.00 of products sold. Of course, not having enough available stock to meet customer demand is even worse than overstocking.

An effective inventory management strategy is key to bucriticaling a successful ecommerce business and leads to an optimized supply chain.

To help you create an ecommerce inventory management strategy that works for you, we’ll look at warehouse management tips and the top inventory management solutions.

What is ecommerce inventory management?

Inventory management is the process of ordering, storing, and selling inventory for your company. It also includes tracking amounts, pricing, location for all your products, and your workflow for keeping tabs on everything.

What is ecommerce inventory management?

A good inventory management process should ensure that you always have enough inventory to meet customer demand without overstocking.

It may come as a surprise to learn that 43% of small businesses in the United States do not track inventory or do so using a manual system, according to Conveyco Technologies.

If you would like to position your ecommerce store ahead of the competition, identifying your reorder points — the pre-determined level of inventory at which you order a restock — and improving inventory forecasting and supply chain management are grat places to starst.

5 common types of inventory management

There are several methods for e-commerce businesses to deal with inventory management. Compare the following types to determine which is best for you.

1) Just-in-time inventory

Also called JIT, just-in-time inventory management is like it sounds. Rather than keeping a large inventory on hand, the JIT method is when a business receives goods only as they’re needed.

Just In Time inventory: Pros and Cons

In ecommerce, for example, that could mean only ordering a supply of Halloween decorations in time for expected demand in October, rther than stocking them all year.

The goal of JIT inventory management is to keep inventory — and the cost of that inventory — to a minimum. This can be an excellent benefit for your exp, but the tricky part is being able to predict demand accuratelyaving enough stock if demand goes up means upset, empty-handed customers. Having too much stock defeats the purpose of the entire method. Therefore, JIT inventory management only works if demand is very predictable.

2) Just-in-case inventory management

This is the opposite of JIT inventory management. Just-in-case, or JIC, inventory management means keeping more stock on hand than you might need to be able to respond to unpredictable demand.

Just in case inventory: Pros and Cons

Also called safety stock, having extra products means there’ll be no sweat if there’s a sudden upticF, for example, an influencer surprises you with a great review a,nd hundreds of orders flood in for a product. It sounds like a dream, but only if you can meet the demand.

The upsides of this type of inventory management are apparent, but so are the downsides. This method can lead to deadstock — items sitting in your inventory that you can’t sell.

3) ABC analysis inventory management

Classifying your stock-keeping units (SKUs) based on ABC analysis is one of the best ways to determine which products deliver the most value to your business, a key inventory management consideration.

ABC inventory: Pros and Cons

Under ABC analysis, three categories of products deliver the highest value to a retail business:

  • High-value products with a low sales frequency
  • Moderate-value products with a moderate sales frequency
  • Low-value products with a high sales frequency

Of course, it’s also possible for a product to not fit into any of these categories. For instance, you might have a low-value product with a low frequency of sales. In this case, removing this product from your catalog might be best altogether.

ABC analysis is meant to help you manage inventory levels for your ecommerce store’s most important products, and any product that falls under one of the following categories deserves particular emphasis in your inventory management strategy.

(A) High-value products with a low sales frequency

Products that yield an exceptionally high profit can preciousble to a company, even if they have a low frequency of sales. For instance, a product that generates $1,000 of profit offers just as much value as selling 100 products that generate $10 in profit each.

It’s recommended that products in this category constitute 10-20% of your total inventory.

(B) Moderate-value products with a moderate sales frequency

The second category of high-importance products is moderate-value products with a moderate frequency of sales.

Products within this category are recommended to constitute 30% of your total inventory.

(C) Low-value products with a high sales frequency

Low-value products with a high frequency of sales are the final ABC analysis product category — and the one that most retail products fall under.

It’s recommended that these products constitute 50% of your total inventory.

4) Dropshipping

This is a no-inventory inventory solution. Ecommerce dropshipping is when a business doesn’t hold its stock. Instead, orders are passed directly to the manufacturer or wholesaler who, who fulfillsse orders.

Dropshipping inventory: Pros and Cons

This the cost and space needed for keeping your inventory or restocking shelves, making it great for first-time operations or testing a concept.

The downside is that order fulfillment — and all the ways it intersects with the customer experience — is left to a third party. If you want complete control over orders from beginning to end, this isn’t the method for you.

5) First in, first out inventory management

First in, first out, also called FIFO, is an inventory system that prioritizes the products in your inventory the longest to be shipped out first.

First in First out inventory: Pros and Cons

FIFO is, of course, a great method for ecommerce businesses selling perishable goods like food or cosmetics. It lowers the risk of a product expiring while still on your inventory shelves, leaving you to eat the cost of unsold goods.

However, this method can be used by any type of business to keep goods moving.

Main challenges to ecommerce inventory management

Here are a few challenges your ecommerce business may face when managing your inventory.

Scaling with a system in place

When you start small, it seems to make sense to simply track everything manually on spreadsheets or even written documents. But if you dream bigger, you need systems in place to match.

As your business scales up, your inventory management process needs to scale with it. Manual management just isn’t going to cut it when you’re processing hundreds, thousands, or even millions of orders and tracking inventory along the way.

Overstocking or overselling

These are two sides of the same coin. Overstocking means having deadstock you can’t sell, which equals wasted money. But overselling without enough inventory means not being able to fulfill orders, or missing out on orders altogether.

Not enough data

Accurate product demanding forecasting requires historical data or at least a trends forecast to give you some insight. Just going with a gut feeling could lead to over or understocking.

Ecommerce inventory management software can help with this, as we’ll discuss later.

Lack of oversight across your whole operation

Keeping an eye on your inventory when you’re running your business out of your garage and selling on a single website is one thing. But as your business gets more complex, so will your inventory management needs.

Having multiple sales channels — such as selling on your own ecommerce website, Amazon, and eBay at one time — means your inventory records need to sync across all those places. If not, you could sell out on one platform, but have plenty available elsewhere.

The same is true if you’re large enough to have multiple warehouses. You need to be able to track inventory across all of them in sync.

Again, inventory management software can help with both these challenges.

6 steps to create a successful inventory management system

Exactly how you manage your inventory is an important business decision, including which method you choose to implement.

If you would like to create an inventory management strategy that is sure to boost your retail business’s bottom line, here are six inventory management optimization tips worth considering.

1) Consider implementing an inventory management tool

Today, many excellent inventory management software solutions are available to business owners. Their useful automation features can help streamline your inventory management process and eliminate human error.

Many also include inventory tracking features that make it easy to follow what flows in and out of your warehouses.

We’ll cover some of the top inventory management software later on. For now, it’s important to understand that leveraging inventory management software solutions is one of the simplest ways to optimize an ecommerce store’s inventory management process.

2) Conduct product demand research

Understanding product demand is key to effective inventory management. If you place purchase orders for all of your products in equal amounts without considering customer demand, you will likely end up with too much of some products and not enough of others.

Instead of falling into this trap, base your inventory replenishment strategy around in-depth product demand research.

Utilizing a tool such as Google Analytics is a great place to start your product demand research. Under the “product performance” section of Google Analytics, you will find a wealth of metrics on how your various products perform, making it easy to estimate product demand.

However, if your online store is relatively new and does not have a lot of past sales to analyze in this manner, research on product demand might be a little more of a guessing game at first. In this case, estimate product demand based on your best analysis of which products will sell the fastest until you generate more sales.

3) Forecast future demand based on historical data

We’ve already mentioned that analyzing past sales via a tool such as Google Analytics is the best way to forecast future demand. As you begin to analyze this information on a regular basis, you’ll have more data to build your forecasts from.

When forecasting future demand based on historical data, there are several important factors to consider. For one, it’s important to identify outliers and anomalies that might lead to inaccurate projections.

For example, let’s say that a viral marketing campaign leads to a large number of sales for a particular product. Based on these results, your forecasting demand for next month’s sales might lead to overstocking once your marketing campaign winds down.

Similarly, forecasting demand for January based on December sales without considering the holiday season’s impact might also lead you to order more products than you should.

As long as you perform a thorough analysis of your inventory data and pinpoint any outliers that might skew your forecast, analyzing historical data is the most effective way to achieve accurate inventory demand projections.

4) Determine reorder points and minimum viable stock levels

The next step is to determine your reorder levels and minimum viable stock levels.

  • Reorder points are the pre-determined levels of stock at which you place another order
  • Minimum viable stock levels are the minimum amounts of product that your online store needs to have on hand to keep up with customer demand without running out of stock
Reorder point formula

It’s also important to consider production times and order fulfillment times. The lead time for products to arrive at your warehouse and the time it takes  to process, prepare, and ship products can both impact your minimum viable stock level calculations.

For example, let’s say you know it takes about six weeks after a purchase order is placed before those products are ready to ship to customers. You will need to place a purchase order for new stock at least six weeks before the date you project you’ll run out of inventory.

It’s also important to note that meeting minimum viable stock levels does not mean stocking the bare minimum product needed to meet forecasted demand. No matter how much research you conduct or historical data you analyze, no demand forecast is 100% accurate.

Only stocking enough products to just meet forecasted demand means that you will run out of stock if actual demand ends up being higher than what you forecast. To prevent this, companies purchase “safety stock,” or extra inventory beyond what they forecast selling.

To calculate how much safety stock you should purchase, you first need to determine your desired service level. Service level indicates the percentage of time a retailer has products in stock.

Using this chart, you can use the desired service level to calculate a service factor. Multiplying this service factor by your demand forecast will tell you how much stock you need to order.

Minimum inventory level formula

According to SKUVault, most retail companies aim for a service level of 90-95%. Assuming that you would like to achieve a service level of 90% and that you forecast selling 100 units per day over the next month, then your minimum viable stock level calculation will look like this:

Minimum viable stock = 1.282 (the service factor for a 90% service level) x 100 units per day x 30 days 

Minimum viable stock = 3,546 units

By plugging your own numbers into this formula, you can determine exactly what your minimum stock level needs to be to achieve your desired service level for a given period.

5) Strategize around seasonality

A company selling pool supplies is likely to see much higher sales during the summer months, while a company selling Christmas ornaments may generate almost all of its sales during the holiday season.

In these two examples, it’s easy to determine how seasonality will affect demand. In other cases, strategizing around seasonality isn’t always straightforward.

While it’s helpful to analyze your products and customer base to determine obvious reasons for seasonal demand fluctuations, the best way to strategize around seasonality is to examine historical inventory data.

Suppose you notice demand trends based on seasonality and determine that these trends are due to the time of year and not some other anomaly. In this case, you should certainly take these seasonality trends into account in your inventory control strategy.
