Inventory Management Systems: Ultimate Buying Guide (2024)


Inventory management software helps stores organize and manage their goods across the supply chain. No matter the size of your business, all retailers need an inventory management system (IMS) to keep track of their products and ensure they have enough supply to meet order demand.

Your inventory management software should maintain your stock levels and make it easier for you to ship products to customers. Modern platforms cut down on manual processes, saving time and reducing the risk of human error. They also integrate with other retail systems—whether that’s your Shopify store admin or your preferred accounting program.

As your business grows, you don’t want to manage orders with an ad hoc pile of spreadsheets and apps. Instead, use one of these best-in-class inventory management systems, which keep all your sales data in a single place.

What is inventory management software?

Inventory management software offers merchants an integrated way to track and report on their stock.

These programs monitor inventory, orders, and fulfillment between a store, its customers, and its suppliers.

High-volume ecommerce companies use digital inventory management systems (IMS) to avoid stockouts, overselling, and optimize fulfillment for the shortest possible delivery times.

Centralizing inventory data is also helpful for companies that sell across multiple channels (including online and offline). Brands that use multiple warehouses or have kitting demands, where orders contain items from different locations, can harness an IMS to stay organized.

Visualization of the seven primary features of inventory management software.

What to look for in inventory management software

Most leading inventory management systems include these seven features:

1. Inventory monitoring

Inventory management systems ensure there’s sufficient stock to meet customer orders. An IMS will alert managers when stock levels run low and automate orders from wholesalers before a product runs out.

2. Inventory control

Inventory control measures help optimize storage space and allocate financial resources to your stock.

3. Multichannel sales alignment

IMS will synchronize inventory data entry across multiple sales channels, so you don’t need to estimate stock levels.

4. Comprehensive reporting and analytics

Advanced reporting and analytics tools highlight which products have the highest and lowest sales volume. These data-driven insights can influence future stock orders.

5. Volume forecasting

Using historical data, IMS can make accurate forecasts and predictions on likely sales volume during a specified time frame.

6. Purchase order generation

IMS enables you to generate and dispatch purchase orders to suppliers, with certain systems offering automated purchase order creation and sending capabilities.

7. Multi-warehouse syncing

Syncing inventory data across all retailer warehouses ensures stock levels are kept accurate.

How to find the best inventory management software

Struggling to choose an inventory management platform? Here are some tips for finding the right inventory software for your company:

Pinpoint needs and features

Start by identifying your IMS requirements. Do you run a small online store that needs shipment tracking, or a larger business looking for multichannel synchronization?

Once you’ve outlined your needs, match them with IMS features like real-time updating, multichannel support, demand forecasting, and in-store POS integration.

Example: Shopify retailer Jen Greenlees, owner of kids-wear store Sydney So Sweet, found her IMS by looking for a specific feature: iPad compatibility.

“The most important thing was that pick-and-ship could be run from iPads, and that the picking screen included the catalog picture of the item being shipped,” Jen says. “This feature cuts our order error rate down to almost zero.

“As a small ecommerce business, the impression a customer gets when they open the first order from us is the most important, so it’s critical to make sure orders are shipped correctly.”

Set your budget

Inventory software costs can vary hugely. Prices are typically based on the number of orders an IMS can process. Remember to factor in all potential costs when budgeting for new software, including:

  • Installation

  • Setup costs

  • Staff training

  • Migration from other systems

  • Hardware for warehouses and stores

Consider the growth of your business when budgeting. For example, you may not need inventory control features right now, but investing in an IMS that optimizes inventory across marketplaces will ensure you have enough stock when sales take off.

Crucially, that means a consistent customer experience at a time when your brand is earning trust and credibility.

Look for integrations

Your new system should complement or replace your existing tech stack—and be customizable to your setup. Check for seamless integration capabilities with your ecommerce platform.

For retailers with physical store locations, check that an inventory management system synchronizes with your POS. That way, whenever an item is sold in-store, your inventory management system will automatically update its stock levels in real time.

If you’re planning on expanding your warehouse storage system, look at whether your inventory management system will integrate with a warehouse management system.

Don’t forget about usability

A system with advanced features is great, but not if it’s too complex for your team. Opt for a solution that’s user-friendly and simplifies your operations. Consider the cost and time you will need to spend training yourself and employees.

Benefits of using an inventory management system

To run a profitable and efficient retail business, you need to have products in stock when customers want to purchase them.

But, between ordering inventory, sales, shipping, and storing, your supply chain can become complicated to manage.

Effective inventory systems automate and handle the complex sides of inventory management so you can focus your energy on selling.

Here are the top four benefits of using an inventory management system:

1. Reduced missed sales

Stockouts cost US and Canadian retailers an estimated $350 billion every year. Not having sufficient inventory to match customer demand results in your business missing out on sales.

Thankfully, today’s inventory systems use RFID tags to reduce out-of-stock messages by up to 30%.

Instead of second-guessing your stock levels, you’ll know in real time exactly how much inventory you have available to sell. A perpetual inventory management system updates inventory levels when a product is purchased, sold, or returned.

2. Loss reduction

Automated inventory software gives you real-time updates on where your stock is located. This visibility is essential if you store stock in multiple locations, such as different warehouses or physical stores. If you sell through several channels, your system tracks this too.

Without thorough tracking systems, it’s easy for inventory to go through the net unnoticed. For example, damaged stock may not be adequately recorded, or inventory may get lost in large warehouses.

Knowing the exact location of your inventory—even if you stock products in different locations, either nationally or internationally—helps lower the time needed to track individual items over your supply chain.

3. Lower warehouse costs

Warehouse storage represents significant operational costs for retailers. But an IMS can help you lower these costs.

Accurate inventory management software reports show which products have the highest and lowest sales volume. By ordering fewer SKUs with low sales volume, you’ll free up more of your warehouse space. You can instead use this space for storing inventory that has a higher sales volume—putting your storage space to better use.

Alternatively, your inventory management system reports may show that by stocking fewer products with low sales volume, you can downsize your warehouse and lower your costs.

4. Manage third-party logistics partners

Fluctuations in demand, seasonality, supply-chain logistics, and a product’s natural life cycle can make managing inventory feel like a moving target. When you work with a third-party logistics (3PL) company, those fluctuations can make it hard to communicate stock needs during sales rushes successfully.

With a centralized system, everybody can access the same information, keeping communications between merchants and 3PLs clear and organized.

Find an inventory system to manage your growth

Inventory software does more than prevent stockouts: it streamlines fulfillment to save you (and your customers) time.

Choosing the right inventory software can mean the difference between a satisfied, growing customer base and a stressful back office that’s struggling to keep up with demand.
