When starting your ecommerce business, you have a lot of decisions to make — but one of the most important is where you’ll store your inventory.

More specifically, you’ll need to decide whether to centralize your inventory, or distribute inventory across multiple locations.

Your inventory management strategy affects almost every other part of your supply chain (including warehouse management, order fulfillment, and overall operational efficiency). For peak performance, you’ll need to choose the distribution system that is best suited for your business.

In this article, we discuss what centralized inventory is, why it’s essential for ecommerce store owners, the main advantages and disadvantages of centralized vs. decentralized inventory, and how ShipBob can help centralize and manage your inventory as you grow.

What is centralized inventory?

Centralized inventory is aninventory storage strategy in which you keep all your stock in one central location. This central hub can be a retail store, a warehouse, or another type of storage facility.

Because all inventory is stored at a central location, instead of different distribution centers, that location also typically houses all or most of thelogistics operations, including order processing and fulfillment.

In a centralized system, all or most functions are managed from a single location, even if you sell from multiple stores or various retail locations.

Why having the right inventory management model in place is so important

If you want to grow your ecommerce business and stay afloat, an effective inventory management system is not a bonus; it’s a need.

The right inventory management strategy unlocks benefits that can transform your operations and position your business to succeed. Here are just a few of the benefits of implementing a good inventory management model in your business.

Better inventory planning

In order to know when to replenish inventory and how much new stock to order, you’ll need accurate inventory counts to go off of.

If your inventory management strategy is up to snuff, you are less likely to miscount inventory, lose SKUs, or waste valuable space keeping obsolete, expired, or excess inventory on the shelf. The right inventory management model helps you track inventory levels, maintain healthy safety stock levels, and meet customer demand.

“ShipBob’s Inventory Planner integration allows us to have all of our warehouse forecasting and inventory numbers in one platform. We can create ShipBob WROs directly in Inventory Planner and have the inventory levels be reflected in our local shipping warehouse and ShipBob immediately.

It also provides forecasting for each individual ShipBob warehouse, so we know how many units we need to ship each week to cover a certain period and also to not run out of stock.”

Marc Fontanetta, Director of Operations at BAKblade

Better customer satisfaction

Customers want to receive precisely what they ordered within an acceptable time frame, and at a reasonable cost. Good inventory management helps prevent stockouts and backorders that disappoint customers, and increases the efficiency of the picking and packing process to facilitate quicker delivery — both of which enable your business to meet and beat customers’ expectations.

Accurate order fulfillment

A well-managed and organized inventory also helps prevent picking and packing mistakes. The right inventory management model ensures that each SKU receives its own dedicated space in your warehouse, to mitigate confusion and improve order accuracy.

Reduced fulfillment & inventory costs

The right inventory management model allows you to reduce inventory carrying costs by minimizing obsolete inventory and dead stock. It also helps you to keep your fulfillment costs low by streamlining the order fulfillment process, as it ensures that inventory is stored optimally and picked accurately.

“When I was shipping orders myself, what I paid per order is the same price now to pick, pack, and ship orders through ShipBob. It’s even much cheaper to ship to certain countries, which used to take ages and often got lost with localized post here.

Now, I have very transparent pricing, and I can easily run and plan my business. I also like that I’m billed right away. My old carrier billed monthly, which would drain a huge sum of Euros from my account at once. My cash flow has improved.”

Leonie Lynch, Founder & CEO of Juspy

Centralized vs. decentralized inventory: which is best?

There are two different strategies that a business can use to distribute and store stock: centralized inventory, and decentralized inventory.

As mentioned previously, the centralized inventory management approach involves a business storing all of their stock at a single warehouse or location, and managing logistical functions such as order fulfillment from that hub. This is the most traditional approach to inventory management, as it simplifies your supply chain management by keeping most critical functions under one roof.

Decentralized inventory, on the other hand, involves splitting a business’s inventory between multiple warehouses in different geographical locations, storing a portion of the overall inventory at each location. Each of these locations perform warehousing and fulfillment functions, and process, pick, pack, and ship orders going to a particular region or area close to them. Retailers may use retail locations or storefronts as micro fulfillment centers, and employ direct store delivery instead of one centralized warehouse.

Neither of these two approaches is necessarily always better than the other; rather, both  have benefits and drawbacks. Ultimately, you will need to weigh the costs and benefits of centralized inventory against decentralized inventory to decide which approach is best for your business.

To help you evaluate your options, here is a breakdown of the pros and cons of centralized and decentralized inventory.

Pros and cons of a centralized inventory and why you should choose it

In most cases, centralized inventory makes inventory control and management simpler. Since you only need to monitor inventory levels in one location, it’s easier to keep track of how much inventory you have left, and properly manage fulfillment for multiple channels at once. Operating only one warehouse also consolidates expenses and decreases facilities and operations costs.

However, shipping orders from just one location means that orders will take longer to reach most of your customers, and will cost more to ship. This could make it more difficult to scale your operations, especially if you plan to sell internationally.

Storing all inventory in one place also means that, in the event of an unexpected disaster that impacts your central warehouse, you won’t have any backup inventory stored in other locations.



  • Slower shipping speeds, higher average shipping cost
  • Makes it harder to scale your operations
  • No backup inventory in case of unexpected disasters

Best for: Smaller ecommerce businesses that ship to a local customer base, sell through multiple channels, and do not plan to scale quickly in near future.

Pros and cons of a decentralized inventory and why you should choose it

With the need for ecommerce retailers to provide fast and hassle-free deliveries, decentralized inventory is quickly gaining in popularity. Storing inventory in multiple strategically placed fulfillment centers allows a business to fulfill orders closer to the customer, which reduces shipping distance, shortens transit time for most orders, and drastically reduces average shipping cost.

Decentralized inventory also allows businesses to allocate inventory based on changes in demand at certain locations. For example, if a certain product is experiencing high demand in one city, retailers can take the inventory from a low-demand warehouse and reallocate it to the warehouse where it will see greater demand.

Overall, decentralizing your supply chain makes it easier to scale your operations — especially even if you want to expand globally — and provides pockets of backup inventory if one warehouse experiences an unexpected disaster.

But there are some drawbacks to decentralized inventory. It is costly for a business to rent, operate, and maintain multiple facilities, which can eat into profit margins. Tracking inventory levels across multiple warehouses is also challenging, and it can be difficult to plan inventory and see the bigger picture of your operations.


  • Faster and cheaper shipping the delights customers
  • Better for scaling your business, especially internationally
  • Backup inventory in case of disasters


  • Extra rent, maintenance, and operational costs
  • Lower margins on certain products
  • Complications in managing inventory across multiple locations

Best for: Growing ecommerce brands with customers all over the country or in other countries, and/or that want to provide fast and affordable 2-day shipping.

Which is better – centralization or decentralization?

The best option for your business will depend on your business’s needs, and what it can afford to compromise on. Traditional centralized inventory is better for small businesses and ecommerce stores that are shipping locally, while decentralized inventory is better for growing ecommerce brands looking to scale, expand internationally, or increase throughput.

Can 3PLs manage decentralized inventory?

Yes! 3PLs like ShipBob have networks of warehouses and fulfillment centers where retailers can store inventory, as well as fulfill and ship orders. The right 3PL partner will also have the technological tools to help you manage various inventories from one platform.

What is the advantage of inventory centralization?

Inventory centralization enables you to keep all inventory in one place, which simplifies inventory management enormously. It is also cheaper than renting and operating multiple warehouses, and makes multi-channel fulfillment easier.

What is the difference between a centralized and decentralized warehouse?

A centralized warehouse stores all of a business’s inventory, and also usually fulfills and ships all orders as well. A decentralized warehouse, on the other hand, is one of many similar warehouses that stores a portion of a business’s overall inventory, and fulfills and ships only orders that are routed to destinations nearby.
