Shopify order management and stock level tracking across sales channels becomes more difficult as demand increases.
If you're at this stage (congrats!), it’s the time most businesses start looking into inventory management solutions for their Shopify store.
Inventory management, also known as inventory control, is the process of acquiring, storing, and distributing your stocks through your different platforms.
It involves tracking how much stock you have left and predicting how much stock you'll need based on sales.
A robust understanding of inventory management and how it works will help you prevent common problems caused by inventory distortion: overstocking, understocking, and overselling.
In this guide, we'll explore:
Now, let’s get started by learning more about inventory management.
Let’s say you own a french fry stall and you want to track sales and revenue and project future sales to create an accurate restock schedule.
You’ll need to know how many potatoes you still have, when your potatoes on-hand will go bad, how many french fry packs you're going to sell, and how many extra potatoes you need in case of emergencies.
Gathering all that information is difficult without a system, especially if you have 10 stalls across the country.
You'll end up buying too many potatoes and wasting money on them going bad, or buying too few and wasting money on lost sales opportunities.
Or worse, you'll accidentally tell your customers that you have more in storage, only to find out you're all out of potatoes.
You can avoid all that trouble with a good inventory management process.
With that, you can track how many items or stock keeping units (SKUs) you have across multiple locations and channels and predict how many more of each item you need so that you can determine when you need to restock and by how much.
Having a product inventory management process will tell you the exact quantity of each of your items in each of your fulfillment channels and whether you're managing your supply chain in-house or through third-party logistics (3PL).
When you open an online store, you have the option of storing your items across multiple warehouses so that you can ship your products out from a location that is closer to your buyer.
The Shopify Fulfillment Network (SFN), for example, is a series of warehouses across different locations that stock, store, and distribute your product to different locations, all powered by Shopify.
You can avoid overselling and disappointing your customers by knowing how much of what you have in each location.
In today’s online world, you need to be omnipresent to catch your audience’s attention—so selling across multiple channels is a must.
But if you're selling on Amazon, eBay, and your own website, it becomes difficult to track how many items you should allocate to each channel, how many items you have left, and how many items you should restock on each channel.
An inventory management system synchronizes your data across different channels and makes restocking suggestions based on past data.
Let’s go back to the french fry stall example and say that you also sell frozen french fries on Amazon, eBay, and your website.
Instead of having to allocate exact quantities to each platform—11 kg to Amazon, 12 kg to eBay, 18 kg to your website, for example—an inventory management system lets you sell all stock (40 kg, in this example) across all sites.
It then updates your total amount of remaining french fries across all your channels every time you make a sale.
If you get one sale on eBay, the number of french fries across all your channels will decrease by one. Simple.
In 2015, retailers lost 1.75 trillion U.S. dollars in revenue worldwide because of stocking issues—going out-of-stock or having too many items that are no longer in-season—and returns.
And that number has risen since, primarily because of the COVID-19 pandemic that disrupted predictions and buying behavior.
Stocking issues result in a loss of sales and negatively impact customer loyalty—if you’re always out of stock, your customers will leave you for more reliable shops.
An inventory management system will keep track of your available items so that you know when it’s time to buy or produce more.
You can also use inventory management apps to tell your customers how much stock you have left per item.

Inventory management is a necessary part of running an effective ecommerce business.
A sound inventory control system will provide insight into your inventory and allow you to understand how often you should restock each of your products.
Using various inventory management techniques can also help you keep an eye on your inventory turnover. This will help you figure out the right amount of stock to keep in your warehouse, thus preventing dead stock.
This is especially important for businesses that sell seasonal items—like winter coats and summer dresses—or perishable goods.
Having a system in place will help you save time and money and satisfy your customers by helping you:
Ecommerce businesses with inventory tracking issues on Shopify often purchase too much stock (resulting in cash flow issues) or sell more products than they can supply.
Both of these problems are equally damaging to a brand’s reputation and bottom line.
In fact, 37% of your would-be buyers will move to a competitor when they find an item is out of stock. By the third time a consumer faces an out-of-stock sign, 70% will switch stores or abandon their purchase, according to Repsly.
An inventory management system helps you provide a better customer experience by preventing overstocking and understocking.
You’ll be able to tell shoppers how many products you have in stock and save your customer support team from the constant back and forth communications with customers.
You can also calculate your economic order quantity (EOQ) within this plan to map out your supply chain operations accordingly.
Imagine booking a plane ticket, getting to the check-in counter, and being informed that your flight was overbooked. You can't get on the plane, and the airport is kind of a drag.
It's infuriating and hurts both customer satisfaction and loyalty.
If you're promised a seat in exchange for money, you want that seat. When an airline becomes unable to fulfill that promise, it tarnishes their reputation and reduces the amount of trust you have in them.
The same thing goes for overselling—selling a product you no longer hold in stock can cause angry customers and result in a tarnished business reputation.
By accurate SKU tracking through inventory management and displaying the status of your items on your distribution channel, you can avoid backlash from unfulfilled promises.
A system will help you track and forecast sales, which will help you predict how much inventory you’ll need during different parts of the year.
From there, it becomes a lot easier to understand how your inventory fluctuates over time and how product demand changes from season to season.
Manually tracking and fulfilling orders is relatively easy when you’re just starting out.
But imagine trying to sell frozen foods—french fries, nachos, chips, dips, popcorn, etc.—stored at different warehouses across the country on Amazon, eBay, your local physical store, and your Shopify website, simultaneously.
Once your business starts growing, it gets progressively harder to scale fulfillment and meet the demands of your customer base.
Managing inventory also becomes a messy nightmare: businesses that don’t have a solid system in place cannot track all the orders and sales that come through different channels.
They’re also not able to see how these orders and sales impact their inventory.
An inventory management system will allow you to easily manage all your sales channels and ensure that each channel has sufficient stock levels.
Inventory management gives you an accurate view of your cash flow and assets, enabling you to better understand how much you should budget for stock or invest in other aspects of your business.
For example, managing your inventory effectively will help you save money on storage costs by allowing you to purchase just the right amount of stock you need.
You’ll be able to make informed business decisions on how to use warehouse space, when to restock products, how to price products, and which products to stop stocking.
This, in turn, will allow you to invest more of your budget into marketing and customer acquisition.
There are all kinds of merchants on Shopify.
Smaller merchants use Shopify inventory management apps and their sales channels to handle their inventory needs.
Enterprise merchants often have an IT team and an enterprise resource planning (ERP) solution that they build and maintain to handle the high volume of restocks and sales.
Mid-sized and growing brands usually use a mix of integrations to balance their sales channels with various fulfillment solutions.

A Shopify inventory app is an automated digital tool that handles Shopify inventory tracking for you.
There are two general types of systems for inventory management: manual and automated.
Using Google Sheets or Microsoft Excel and inputting sales data, generating your SKUs, and updating your sheets every time you make a sale is the manual way of tracking.
A Shopify product inventory app, on the other hand, automates the entire process with little to no input from you.
Even if you know how to track inventory manually, doing so leaves more room for human error and wastes time on manual data entry and verification.
Choosing the right inventory control app will help you and your team free up time to focus on more critical aspects of your business.
A good inventory control app will help you streamline and automate inventory management, save on and reallocate resources, and help you forecast trends.
You'll also increase team productivity and accuracy because employees won't spend large sums of time manually tracking inventory.
You should look into an inventory management app if you:
There are different inventory management apps, each with its distinct features, advantages, and disadvantages.
The best inventory management software for ecommerce provides detailed online store inventory tracking, auto-generated product orders, integrations with other apps, and a comprehensive data dashboard.
The app you choose should have:
You should be able to track all orders and order fulfillment information and receive notifications on when to purchase additional stock.
Look for an application that accurately tracks the number of items you have at any given moment, updating within a few minutes of a sale so that you can prevent overselling.
The inventory app you choose should play nicely with the other apps you use.
You want an application with a Shopify warehouse integration. Look out for integrations with your accounting tools, website ecommerce tools, POS systems, and other tools in your tech stack.
While there are many variables involved with forecasting sales, your ecommerce inventory management app should offer a ballpark projection of market trends and growth rates.
Some applications even automate purchase order (PO) generation as soon as one of your items is low in stock, predicting the reorder quantity based on sales forecasts.
A POS integration is crucial if you also sell from a physical store.
This will allow you to automatically sync online and in-store orders and stock levels and make sure there are no discrepancies between stock levels in your online and offline sales channels.
Your app should offer reports and inventory analysis tools that fit your inventory management methods.
The app should generate various real-time reports and allow you to customize them as you see fit.
