Stock-keeping units, or SKUs, are crucial tools for inventory management. They provide identification for your products and help businesses keep track of available inventory. You can also use them to track sales trends, optimize future items and improve the customer experience at your stores.
However, managing the number of SKUs in your inventory is important. Focusing too much on expanding inventory might result in extraneous products and a lack of profit. With a process called SKU rationalization, you can optimize SKUs and eliminate products that underperform or don’t sell at all. In turn, you can maximize profits and maintain your inventory more efficiently.
Read on for more information about the SKU rationalization process and how it can help your business.
What Is SKU Rationalization?
Retail businesses’ top priority is the promotion and sale of products. As companies grow in popularity and expand their customer base, they might also grow their product inventory. While introducing new items can be highly beneficial for businesses, adding too many new SKUs can cause overstock. If products undersell, you could lose money in production costs. They could also overflow your inventory, making inventory management more challenging.
SKU rationalization is the process of analyzing your current inventory and getting rid of products that aren’t selling well. During your analysis, you can decide which products to add, remove or keep in stock. By removing underperforming products, you can improve your inventory organization. SKU optimization allows you to focus on high-demand products, which increases profits and customer satisfaction.
For example, technology vendors use SKU rationalization as new items debut. Electronic retailers remove outdated or unpopular items from their inventory as they make room for the latest upgrades. They might pull headphones or cellphones from a certain date, such as three or more years. Customers are likely more interested in the newest editions, so removing older iterations doesn’t impact their preferences.
Why Is SKU Rationalization Important?
The SKU rationalization process is essential for multiple reasons:
Reduces expenses: If you have too many products available, you’ll likely have to pay multiple suppliers and additional shipping fees. When you only focus on the products that sell well, you can maximize profits and keep your warehouses from overcrowding. Essentially, you focus on the products that drive growth for your business.
Streamlines inventory process: Effective inventory management is crucial for all businesses. You can ensure accurate stock levels and provide an enhanced customer experience. With SKU rationalization, you maintain a manageable and profitable stock. The inventory is much easier to manage when you don’t have extraneous items.
Optimizes your catalog: Lastly, SKU optimization allows you to enhance your catalog. You can set your business apart from competitors by offering the most popular products and eliminating outdated ones.
The Benefits of SKU Rationalization
A consistent analysis of your products offers many benefits. SKU rationalization allows you to measure the profitability of each product in your inventory. You can use these metrics to enhance your business in many ways, including:
Raising profits: If a product doesn’t result in a net profit, it might cause your company to lose money overall. From shipping costs to storage space, each item costs additional prices. And with fewer options on your shelves, customers might be able to make purchase decisions more confidently. You can avoid handling fees for extraneous products while enjoying increased sales. Overall, SKU rationalization is an excellent option if you want to increase earnings.
Improving efficiency: The fewer SKUs you have, the less time you have to spend on production and shipping. A more organized warehouse leads to quicker turnaround times, so your customers receive products quickly. Your business can streamline many packaging and distribution processes with fewer items to manage. In turn, your efficiency improves, and customer satisfaction rises.
Strengthening brand awareness: If your business carries leading products and brands, you can enhance your brand’s reputation. Inventory efficiency leads to quick distribution times. When customers receive high-quality products quickly, their satisfaction grows. And the happier your customers are, the more likely your consumer base will grow.
How to Optimize Your SKUs
If you want to optimize your SKUs, it’s best to make a plan first. Here are steps you can take for SKU rationalization:
Identify your target audience: It’s wise to start with your intended audience. Consider the values of your customers and your business. Products that align with these values are more likely to sell consistently because customers will be more interested. You can use these values as you analyze your products for optimization.
Analyze SKUs: Next, it’s time to analyze your current SKUs for their profitability. For each SKU, monitor its storage costs, production times, future sales projections, labor costs and popularity. Afterward, you can use the results to decide which products to remove or keep. For example, if an item has high storage and labor costs but poor selling performance, you might choose to remove it from your inventory. But if a product sells extremely frequently and has high sales projections, you would probably keep it in your stock.
Organize product catalog: As you alter your product inventory, it’s also a good idea to reorganize your catalog. If you remove an item, make sure to eliminate it from all online or in-store inventory logs to reduce customer confusion. As you implement new items, group them with similar products to maximize organization. An organized catalog can also help you notice which items need replacements due to lack of variation.
Track performance results: Lastly, you should closely track product performance after your catalog edits. Check whether your alterations helped with storage optimization, profitability and operational costs.
You should perform SKU rationalization once or twice a year to ensure inventory optimization. Performing it consistently also allows you to track sales projections and other significant business data. This method is beneficial for streamlining inventory processes and increasing your profits.

“The core of maturity, that I see, is starting with a unified view of inventory. I’ve got to be able to accurately represent what do I have, make sure that I know where it’s located so I can get it to my customers quickly.”
— Troy Graham, Descartes
What is the first thing I should fix if I want to scale operations?
Start with a unified view of inventory. The core of maturity starts with being able to accurately represent what you do have and make sure that you know where it’s located to get it to customers quickly. Without a unified view across your warehouses, 3PLs, and vendors, you cannot make the best decisions because you don’t have the best information at hand.
With Inventory Visibility, Businesses Can Make Smarter Allocation Decisions
Once inventory is centralized, businesses can move from reactive updates to intentional allocation. They can decide how much inventory to expose to each channel, when to use buffers, which marketplaces need extra protection, and how seasonality or campaign performance influence availability.
Once I know what inventory I have, how should I decide where to make it available?
Inventory allocation should reflect where orders are coming from, where marketing is working, and which channels carry the most risk. Once you know what you have and where it is located, you can think more strategically using centralized inventory to make prioritization happen automatically. One fertilizer company lost a little over 5,000 orders in one weekend because someone manually uploaded the wrong available inventory to Amazon.
Better Inventory Data Improves Planning, Purchasing, and Growth Bets
Better visibility turns inventory data into a planning tool. With insight into sales velocity, inventory levels, vendors, and channel performance, businesses can make more informed replenishment decisions, avoid overbuying, and test new product lines or vendor-supplied inventory without taking on unnecessary risk.
“You have to have unified inventory to know how to price your products just at that basic level. I can’t price my products if I don’t know the true cost to get it.”
— Mike Bernico, Flxpoint
How does better inventory data help me make smarter buying decisions?
It lets you measure whether your plan is working before you commit more capital. A key question becomes: “Did my plan work? Am I overleveraged in one place or another?” Centralized systems can also help businesses test new product lines or vendor relationships by looking at sales velocity by channel, allowing them to take risks in a calculated and measured way.
Intelligent Order Routing Turns Inventory Complexity Into Automation
Once inventory and supplier data are reliable, businesses can automate fulfillment decisions. Orders can be routed based on cost, speed, margin, location, warehouse priority, vendor fallback, split-shipment rules, or customer expectations. This helps hybrid fulfillment scale because every order does not need a manual review.
How do I decide the best way to fulfill each order?
There is no single answer, which is why order routing needs to account for the context of each order. Intelligent order routing is not just sending an order to someone who has stock; it is taking each and every order and treating it like its own unique use case. Depending on the order, the business may prioritize speed, margin, an internal warehouse, vendor fallback, or preventing split shipments.
Supplier Inventory Sync Extends Inventory Beyond the Four Walls
For hybrid fulfillment to work, supplier inventory needs to become part of the operating model. Supplier sync does not always require advanced technology; it can happen through automated files, FTP, email, APIs, EDI, or ecommerce storefront integrations. The key is replacing manual updates with automated, reliable supplier data.
Can supplier inventory really be treated like part of my own inventory?
Yes, but the goal is not necessarily to force every supplier into a complex integration. Real-time supplier sync can be defined as any way to get an automated update from a supplier, such as Google Sheets, email, FTP, API, EDI, or ecommerce storefront connections. The key is that accurate supplier stock is foundational. If you don’t have an accurate view of what is in stock with your suppliers, you cannot tell your sales channel accurately what’s available.
Exception-Based Workflows Keep Humans Focused Where They Matter
Automation does not remove people from the process. Mature operations let technology handle the routine majority while humans focus on exceptions, such as high-value orders, fraud risk, compliance requirements, restricted products, export rules, or unusual fulfillment scenarios.
If my business has special cases, can automation still work?
Yes. The point is not to automate every possible decision; it is to automate the routine work and surface the exceptions. Businesses should not have to look at every single order. Instead, technology can highlight high-value orders, risky locations, or compliance requirements. The goal is to take care of the 80% of workflows that are obvious while still allowing human review when specific exceptions arise.
The Right Inventory Technology Should Fit the Business, Not Overwhelm It
Software decisions should be based on business fit, not popularity, feature volume, or broad “all-in-one” promises. Growing ecommerce businesses should identify their highest-impact bottleneck, prioritize what matters now, and choose technology that is right-sized but flexible enough to support future phases of growth.
How should I choose software without overbuying or picking the wrong system?
Start with your priorities, not the biggest feature list. Avoid an all-in-one system that claims to “do everything under the sun” and look for a “best of breed approach” with systems that can scale as you add channels or vendors. The practical advice is to stack rank what matters now, make sure the system can support future phases, and choose technology that fits your business rather than overwhelming it.

Ecommerce Fulfillment Operations FAQ
What Is Ecommerce Fulfillment Operations?
Ecommerce fulfillment operations are the processes that move an online order from purchase to delivery. This includes managing inventory, syncing product availability across channels, routing orders to the right warehouse, 3PL, supplier, or vendor, and making sure the customer receives the right product on time. As discussed in the webinar, fulfillment is no longer limited to “what’s in my warehouse these days”; growing businesses may rely on internal warehouses, 3PLs, marketplace fulfillment services, and supplier inventory at the same time.
What Are Ecommerce Fulfillment Operation Examples?
Examples of ecommerce fulfillment operations include updating inventory across Shopify, Amazon, Walmart, and other sales channels; allocating inventory to specific marketplaces; sending orders to an internal warehouse, 3PL, or vendor; syncing supplier inventory through files, APIs, EDI, email, or FTP; replenishing warehouse stock based on sales velocity; and flagging exceptions such as high-value orders, compliance requirements, or restricted products. In the webinar, the speakers also discussed hybrid fulfillment examples where a business may fulfill some products from its own warehouse and use vendors as a fallback or extension of available inventory.
How Can I Track My Inventory at an Ecommerce Fulfillment Center?
The best way to track inventory at an ecommerce fulfillment center is to create a unified inventory view that shows what is available, where it is located, and how that inventory connects to each sales channel. That means tracking inventory across internal warehouses, fulfillment centers, 3PLs, marketplace fulfillment programs, and supplier locations instead of relying on disconnected spreadsheets. The webinar emphasized that businesses need to “accurately represent” what they have and know where it is located so they can get products to customers quickly.
How Can I Connect My Inventory to My Supplier?
You can connect supplier inventory through several methods, depending on what the supplier supports. The webinar discussed low-tech and advanced options, including automated Excel or CSV files, Google Sheets, email updates, FTP servers, APIs, EDI, and direct connections to ecommerce storefronts such as Shopify, BigCommerce, or Magento. The key is to ask suppliers how they share inventory today, then use a system that can automate that data flow instead of manually copying supplier inventory into spreadsheets.
What Is Ecommerce Order Routing?
Ecommerce order routing is the process of deciding where an order is fulfilled from after a customer buys. In a simple operation, every order may go to one warehouse. In a more complex or hybrid fulfillment model, the best fulfillment source may depend on inventory availability, shipping speed, cost, margin, customer location, warehouse priority, vendor fallback rules, or whether the order should be split. The webinar described intelligent order routing as treating each order like its own use case, so businesses can automate the best fulfillment decision without manually reviewing every order.
