If you split inventory across multiple fulfillment centers and/or have a robust multi-channel distribution strategy, inventory technology makes it easy to track your products across channels in real-time. The question is: what’s the best way to manage your inventory? Gone are the days of using spreadsheets, paper, and other inventory sheet templates

To easily track inventory, many ecommerce businesses are turning to inventory apps for solutions. Depending on how you organize and store your inventory, inventory apps offer the option to organize and more easily manage ecommerce inventory by volume, type, SKU, and more.

In this article, you’ll learn what to look for in an inventory app and how to choose the right solution for your business. 

What is an inventory app?

Inventory apps help you track, organize, and manage inventory in real-time across multiple channels and warehouses. They can either be viewed on a web browser and/or mobile device and can provide real-time updates.

What matters most for inventory apps?

When researching inventory apps, it’s important to find the right solution that fits your unique business. Features like inventory volume, budgeting, tracking, and integrations with other apps are some of the key features you’ll want to consider. 

1. Inventory days on hand

Tracking inventory days on hand can help you understand how quickly your inventory levels deplete on average. By tracking this measurement combined with inventory forecasting, you can get insight into how long products stay on the shelf and make better predictions on when to restock. Inventory apps make this easy by providing this data for you. 

2. Carrying costs

Warehousing inventory can be costly if products are sitting in the warehouse for too long. Along with inventory days on hand, with an inventory app, you can track how long your products are sitting on shelves compared to other locations, whether it’s in a warehouse or at a brick-and-mortar retailer. This will give you a better sense on how to cut down on carrying costs

3. Calculating your SKU count and product variants

Using SKUs to designate inventory is an industry best practice, especially if you partner with a 3PL that fulfills orders for you. By using an inventory app that makes it easy to organize products by SKU, you’ll be able to see how many SKUs you have based on different product variations, such as color, size, etc. 

4. Integrations

It’s important to look for an inventory app that has an integration for your online store so you can easily control stock, such as Shopify, BigCommerce, or WooCommerce. That way, it’s easier to sync inventory levels and communicate what’s in stock or out of stock on your website in real time. 

5. Inventory reorder points

A reorder point (ROP) is the minimum unit quantity that a business should have in available inventory to meet demand. To calculate ROP, you’ll need the sum of lead-time demand and safety stock in days. The right inventory app will not only provide insights like this, but also allow you to automatically set reorder points based on historical inventory data and gain a better understanding of your ideal reorder quantity

6 best inventory apps compared

There are dozens of inventory apps available. Here are some of top seven apps to consider for your ecommerce business.

1. ShipBob

While ShipBob is not a standalone inventory app, we offer a lot of the same features through our end-to-end tech-enabled order fulfillment solution. Our free inventory management software is built-in.

Merchants are given the tools, data, and reporting necessary to efficiently manage their inventory in real-time across multiple ShipBob fulfillment centers all from one dashboard. 



  • You have to be using them for fulfillment (and they are best for ecommerce brands fulfilling 200 orders per month)

2. On Shelf

On Shelf is an inventory management app for small businesses. Ideal for salons, restaurants, and bars, On Shelf is a good option for smaller operations just getting started with inventory management. 


  • Easy-to-use interface
  • Easily import products in through a .txt file


  • Can’t see how much the pricing is before you sign up

3. Cin7

Cin7 is an inventory management solution for multi-channel brands. It synchronizes inventory and orders across every sales channel and stock location.

How it compare to ShipBob

myStock is a good option for newer, smaller ecommerce businesses that are self-fulfilling and only handle a few orders a month.

“Another ShipBob integration I love is Inventory Planner. It saves me hours every week in Excel spreadsheets, and I can raise a PO in minutes when it used to take me hours.

For every order I placed for years, I was ordering too much or not enough. Between inventory forecasting tools and the ability to auto-create WROs, we don’t have stockouts much anymore. I sleep better at night.”

Wes Brown, Head of Operations at Black Claw LLC
