What is warehouse optimization?

Warehouse optimization is the strategic process of improving the efficiency, productivity, and accuracy of warehouse operations. The objective is to minimize costs, maximize throughput, and enhance the customer experience through a combination of improved warehouse layout design, technology integration, process reengineering, and employee training. 

For ecommerce brands, this optimization aims to streamline receiving, picking, packing, shipping, and return processes. By doing so, ecommerce businesses help ensure orders are processed in the quickest and most cost-effective way possible.

Here’s why you need to optimize your warehouse

A warehouse is more than just a storage facility; it’s the place where you get to prove why your customers should trust you. It’s what enables you to create a memorable unboxing experience or provide affordable 2-day shipping.

Yet, despite its central role, warehouse efficiency isn’t always at the top of mind for ecommerce businesses. It’s certainly not the most glamorous aspect of running an ecommerce business – in fact, it can be expensive, complicated, and time-consuming.

However, those willing to spend the time, money, and resources to invest in improving their warehouse benefit from these three key advantages:

  1. Improved productivity: An optimized warehouse streamlines every process. This means less time wasted, quicker turnaround, and the ability to handle a larger volume of orders. 
  2. Greater customer satisfaction: When customers receive their orders on time and in perfect condition, they’re more likely to come back for more. In contrast, delayed or incorrect orders can have an outsized negative impact. An optimized warehouse helps you consistently meet or exceed customer expectations, turning one-time buyers into repeat customers or even vocal members of your brand community.
  3. Increased profitability: The quicker you can move products in and out of your warehouse, the better your cash flow will be. Additionally, efficient space utilization can reduce storage and labor costs, which helps protect your bottom line.

The benefits of warehouse optimization

Warehouse optimization offers benefits that go far beyond operational improvements. It has the power to reshape a business’s logistical capabilities, enabling a brand to scale further.

Let’s dig deeper into a few of the most important benefits of warehouse optimization.

Better inventory management

Inventory management is no small task—especially when your business offers hundreds, thousands, or even tens of thousands of SKUs. Manually keeping track of which ones are running low and which are overstocked is a cumbersome process that’s prone to human error. 
But with real-time inventory management systems directing inventory flow and recording inventory movement across a warehouse, businesses have access to instantaneous data regarding stock levels, order status, product locations, and more.

“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

By leveraging these real-time insights to, companies can:

  • Reduce stockouts: Nothing turns off a potential customer more than finding out their desired product is out of stock. Real-time inventory updates help businesses react swiftly, ensuring stock levels match the demand.
  • Optimize storage space: When you understand which products are fast-moving and which are not, it’s much easier to use your storage space efficiently. 
  • Improve forecasting: Accurate inventory data means better demand forecasting, helping businesses plan for the future more effectively.

Accurate order picking

In ecommerce, warehouse picking and packing errors are costly—not just in terms of monetary loss, but also in terms of customer trust. By introducing smart order picking software and easily readable labels and barcodes into your warehousing operations, pickers are much less likely to make mistakes. 

Increasing order picking accuracy through warehouse optimization naturally: 

  • Reduces return rates: The cost and hassle of handling returns due to picking errors can be significant. Accurate picking minimizes this risk.
  • Enhances customer trust: Delivering the correct product on time, every time, enhances customer trust and loyalty.
  • Improves operational efficiency: Fewer errors mean fewer re-picks, saving both time and money.

“One of the biggest reasons we went with ShipBob is the multiple checks from start to finish. The WMS makes it really hard to send out the wrong product. It still happens on rare occasions – but it happens a lot less than before. Before we implemented ShipBob’s WMS, our order accuracy rate was around 92%. Now we’re at 99.7% for order accuracy, which equates to 2,100 less mispicks a year on average.”

Jourdan Davis, Operations Manager at Pit Viper

Effective kitting & assembly

Kitting is essentially the process of preparing inventory to be sent out. This can be anything from removing an item from the warehouse’s packaging to combining multiple SKUs into a single package so that they can be sold as a “kit”. Assembly, on the other hand, refers to partly assembling a product before shipping it to the end customer.

Both of these processes take time, attention to detail, and are prone to errors when the correct workflows aren’t in place. By optimizing your warehouse for effective kitting and assembly, you can achieve:

  • Cost savings: An efficient kitting and assembly process reduces the amount of time it takes to prepare each order, saving on labor costs.
  • Enhanced product offerings: An unoptimized warehouse may not be able to offer “kits” or pre-assembled products. Offering these can differentiate a business in a crowded market and lead to higher average order values.
  • Inventory efficiency: Tracking inventory becomes more streamlined when items are kitted, reducing potential errors and stockouts.

Fast shipping & receiving

The speed of shipping can make or break a customer’s experience. If your warehouse is unable to quickly unload, inspect, and store products, this can lead to significant bottlenecks, inaccurate inventory numbers, and missed sales opportunities. 

An optimized warehouse facilitates faster and more efficient shipping and receiving processes, resulting in:

  • Enhanced customer satisfaction: Meeting or exceeding delivery expectations leads to satisfied customers and more positive reviews.
  • Competitive edge: Offering expedited shipping options can provide a competitive advantage in a market where customers expect fast delivery.
  • Operational savings: Faster warehouse receiving processes mean products are available for sale sooner, reducing potential lost sales due to stockouts.

Swift returns processing

Returns are an inevitable part of ecommerce, but an optimized warehouse can turn this challenge into a strategic advantage. Having an optimized warehouse that can streamline the returns process helps with:

  • Customer retention: The average ecommerce return rates range between 20-30%. A hassle-free and efficient return process can lead to higher levels of customer satisfaction and retention.
  • Inventory turnover: Efficiently processed returns can be restocked and resold more quickly, reducing holding costs.
  • Data insights: Tracking and analyzing returns can provide valuable insights into product quality, customer preferences, and potential areas of improvement.

“About a year and a half after building out our business, we figured it was time to optimize some of our processes, including returns. The ability to work with one of the co-founders of ShipBob to launch a new, custom returns process was awesome. Returns were taking a lot of time and resources to process on our end, but ShipBob was super helpful and critical in creating a solution for us.”

Nikolai Paloni, Co-Founder of Ombraz Sunglasses

7 warehouse optimization tips (from the experts)

A truly optimized warehouse balances technology and integrations with streamlined warehouse processes and proper training. Only when these three things align will a business experience the full benefits of an efficient warehouse.

To achieve that balance, consider following these best practices as you begin your warehouse optimization journey.

1. Assess & understand your current warehouse setup

First things first: you can’t fix what you don’t know is broken. 

Start by conducting a detailed assessment of your current warehouse setup, staffing levels, and technology. Are employees tripping over each other due to a cluttered layout? Is half your warehouse space gathering dust? Does your order accuracy decline when order volume increases? 

Think of this stage as a diagnostic test; the results will indicate what needs to be improved. 

You might discover an opportunity to better organize your warehouse, invest in new equipment, or upgrade your warehousing racks and shelving systems. Whatever it may be, this initial evaluation is your roadmap for actionable changes. 

2. Define your objectives & pain points

Now that you’ve audited your current setup, you need to define what it is you’re trying to achieve.

Ask yourself: what is the brand aiming for? Is it: 

  • Reducing shipping times to improve customer satisfaction?
  • Cutting down operational costs to improve profitability?
  • Increasing accuracy in picking and packing to reduce returns and associated costs?
  • Improving space optimization to satisfy growing customer demand?

Specific goals will offer you direction and purpose, allowing you to better plan out your strategy. 

During this stage, remember to keep the customer a priority. For example, if one of your objectives is to reduce costs, but that in turn compromises the speed or accuracy of shipping, you might inadvertently affect customer satisfaction negatively. 

Therefore, try to find a balance between operational efficiency and customer-centric goals.

3. Get your inventory management right, first

Once you’ve assessed your current setup and defined your objectives, the first warehouse function to optimize is your inventory management. From reducing holding costs to improving cash flow, the right inventory control techniques and systems can drastically improve the efficiency of your warehouse.

Imagine this: you roll out a fantastic sale on a particular SKU, only to realize after the fact that you’ve got very few units left to sell. Alternatively, say you have mountains of products collecting dust, and they go obsolete before you’re able to sell them. 

Real-time tracking is the solution to these sorts of issues. Deep visibility into inventory movement in your supply chain provides you with the best data on which products are running low, and which need to be cleared out. 

Inventory management tools and techniques can also be a lifesaver when it comes to seasonal fluctuations in demand. Some software solutions like ShipBob’s even offer demand forecasting based on your order history, so you can study past sales patterns to stock up on seasonal favorites ahead of time. 

4. Adopt a warehouse management solution (WMS)

A well-chosen warehouse management system (WMS) centralizes data and automates many of the tasks that would otherwise be labor-intensive and prone to error (such as receiving, shipping, storage, picking, kitting, packing, etc.).

A WMS streamlines these processes and provides a single source of truth, so you aren’t left guessing or cross-referencing multiple systems to figure out what’s happening in your warehouse. 

Adopting a warehouse management system will require an initial investment up front. However, in the long run, the benefits far outweigh the costs. With a WMS you’ll be able to achieve:

  • More accurate inventory counts
  • Better order efficiency
  • More productive warehouses
  • A reduction in operational costs
  • Faster shipping

5. Consider Lean warehousing techniques

Incorporating principles of Lean management helps reduce time spent on non-value-added activities. Originating from the manufacturing sector, Lean is all about doing more with less.

For example, your employees may be walking an extra 200 steps just to pick an item that’s not strategically placed. Lean techniques would pinpoint this inefficiency, which you can then work towards improving. It’s like feng shui for your warehouse; every element has a purpose and a place, thereby streamlining operations.

6. Invest in staff training

A warehouse is only as efficient as its least-trained employee. If employees aren’t properly trained, they won’t perform tasks to the best of their abilities. 

Holding periodic training sessions and implementing a labor management system to measure the efficacy of employees will help you identify areas where further training is needed. Investing in staff training ensures that everyone understands not just the what, but the why and the how of their tasks. This leads to fewer errors and less rework.

7. Outsource warehouse management to a 3PL

Optimizing a warehouse to compete with today’s retail giants is no easy task. It takes time, significant investment, and expertise that many businesses simply don’t have in-house. This is where outsourcing to a 3PL or logistics partner can simplify things.

A 3PL specializes in all things logistics, from warehouse inventory management to warehouse putaway, picking, packing, shipping, and so much more. This means they have the experience and smart warehousing technology to optimize each step of the supply chain. By handing off your warehouse management to an expert partner, you’re essentially plugging into their existing infrastructure, benefitting from their economies of scale, and freeing yourself to focus on other core aspects of your business.

Emerging trends and the future of warehouse management & optimization

As technology progresses, businesses must find ways to leverage tech advancements to further optimize operations–especially within their warehouses. 

Advancements like artificial intelligence (AI), robotics, and machine learning are revolutionizing everything you can do in an ecommerce warehouse, from inventory management to order fulfillment. AI algorithms can predict inventory needs with uncanny accuracy, and robotics 

can improve warehouse efficiency by automating the picking process.


Big data and analytics also play a large role in the future of warehouse optimization. As the volume of data generated by ecommerce businesses continues to grow, there is more need for sophisticated data collection and analysis tools. These metrics can provide insights into customer behavior, operational bottlenecks, and forecast future demand based on historical data.
