Best ecommerce inventory management software: What to look for and top options
Inventory management software is the backbone of a successful ecommerce business. It tracks products, orders, and stock levels across every place you sell and store goods, so you can avoid stockouts, overselling, and overstocking, and keep customers happy.
With so many options, the hard part is choosing. This guide explains what inventory management software does, what to look for, how to choose, and how seven options compare, so you can find the right fit for how you sell.
What is inventory management software?
Inventory management software (also called inventory tracking software) automates the work of tracking stock. It keeps counts accurate across sales channels, warehouses, and locations, reduces the risk of human error, and automates routine tasks such as reorder alerts and stock updates. With a clear view of what you have and where, you can decide what to buy, when to replenish, and how to price.
Some systems also cover supplier management, purchase orders, order management, and warehouse tools like barcode scanning. Others focus on one area, so what you need depends on how you sell. For the fundamentals, see our introduction to inventory management.
Signs you need dedicated software
- You track stock in spreadsheets, and the numbers disagree with what’s on the shelf
- You oversell or run out of popular items because channels don’t update each other quickly enough
- You sell on more than one channel, or hold stock in more than one location
- Counting, reordering, and updating listings take hours that you’d rather spend selling
- You operate a store or pop-up as well as an online shop and need one view of stock
What to look for in inventory management software
Every business is different, but these capabilities matter for most ecommerce sellers.
Centralized stock across channels and warehouses
One source of truth for stock prevents discrepancies and overselling. It’s also where many retailers fall short. In Linnworks’ State of Commerce Ops 2026 report, only about a third of mid-market retailers (33.2% in the UK and 37.2% in the US) reported excellent inventory visibility across channels and warehouses, even though the average retailer sold on more than four marketplaces or channels.
Fast stock sync and overselling protection
Ask how quickly the system updates stock across channels after a sale, and whether you can set inventory thresholds to protect your last few units. Slow sync is a common cause of oversells.
Demand forecasting and reorder alerts
Forecasting uses historical sales and other factors to predict demand, so you can make better purchasing and stocking decisions. Reorder alerts tell you when stock falls below a threshold, so you can replenish before you run out. See our guides to forecasting inventory and the safety stock formula.
Multi-warehouse and 3PL support
If you hold stock in several locations, including a 3PL or fulfillment centers, the software should track stock levels, transfers, and shipments across all of them. It should also help you optimize warehouse operations as you grow.
Barcode scanning and batch or expiry tracking
Barcode scanning speeds up receiving, picking, and counts, and cuts errors. If you sell perishable goods or items with expiry dates, batch and expiry tracking helps you sell older stock first and maintain quality.
Channel and platform integrations
Your software should connect to your webstore platform, marketplaces, shipping carriers, and accounting tools, so data flows between them without manual re-entry. Check that it supports every channel you sell on today and the ones you plan to add. See our guide to managing inventory across multiple channels.
Point of sale (POS) support
Many ecommerce businesses also sell in physical stores or at pop-up events. If that’s you, make sure the software connects with your point of sale, so stock stays accurate whether a sale happens online or in person.
Supplier and purchase order management
Keeping supplier details and purchase orders in the same system helps you maintain better supplier relationships, negotiate terms, and simplify purchasing. Look for supplier performance reporting if lead times and reliability affect you.
Reporting and analytics
Good reporting and analytics show stock levels, turnover, fast and slow movers, sales, and profitability by SKU and channel, so you can act on the data. See our inventory reporting guide.
Ease of use, support, and room to grow
An intuitive interface cuts training time and mistakes. Strong onboarding and support help you get value faster. And the system should handle more SKUs, orders, channels, and users as you grow, without forcing a costly switch later.
How to choose inventory management software
Step 1: Assess your ecommerce business needs
Start with a clear picture of how you operate. Write down:
- The number of SKUs and how often your catalog changes
- Your sales channels, today and in the next 12 months
- Your warehouses, locations, and 3PLs
- Monthly order volume and seasonal peaks
- Special requirements, such as batch or expiry tracking, kits, or manufacturing
- The tools it must connect to, such as your webstore platform, accounting software, POS, and shipping carriers
Step 2: Determine your budget
Look beyond the monthly subscription. Consider:
- How pricing scales: by users, order volume, SKUs, or channels
- Implementation and onboarding costs
- Paid add-ons for features like warehouse tools, forecasting, or listings
- Hardware, such as barcode scanners and label printers
- Training time, and the cost of mistakes you’ll avoid
The cheapest option isn’t always the best fit. Weigh cost against the time and errors you’ll save, and expect pricing to change, so check each vendor’s current plans.
Step 3: Evaluate the features and capabilities of each system
Once you have a shortlist, test each against your requirements. Ask:
- Does it connect natively to every channel and tool I use?
- How quickly does stock update across channels, and how does it prevent oversells?
- Does it support my warehouse workflow, including scanning, picking, and returns?
- Can I automate reordering, routing, and other repetitive tasks?
- Do the reports show what I need by SKU and channel?
- What’s included in the base price, and what costs extra?
Step 4: Consider the user experience and customer support
The quality of onboarding and support often decides how well a system works in practice. Check:
- How the vendor supports onboarding, and how long a typical go-live takes
- Support channels and hours, and whether you get a named contact
- Documentation, training, and tutorials
- How easily your team can learn the interface, ideally by letting them try it
Step 5: Take advantage of free trials and demos
Use trials and demos to test the system with your own situation. They let you:
- Run your own data and products through it, instead of the vendor’s sample set
- Test your hardest workflow, such as a multi-warehouse transfer or a return
- Get your warehouse and support staff to try it, not just managers
- Check how well it integrates with your existing tools
- Ask about limits on users, orders, and channels
Step 6: Seek recommendations from other ecommerce business owners
Finally, talk to people who’ve already made the choice. Their experience can help you:
- Learn what the day-to-day experience is really like
- Find out how long onboarding took and what went wrong
- Spot problems that demos don’t reveal
- Ask vendors for references from sellers like you, and compare them with independent reviews

FAQs: inventory management software
Inventory management software tracks your stock across sales channels, warehouses, and locations, and automates tasks such as stock updates, reorder alerts, and reporting. It’s also called inventory tracking software.
Businesses track stock using a perpetual system, which updates counts continuously as stock moves, or a periodic system, which updates counts at set intervals. They also use methods and strategies such as just-in-time inventory and dropshipping to decide how and when to hold stock.
Common methods include economic order quantity (EOQ), ABC analysis, and material requirements planning (MRP). Many businesses also hold safety stock as a buffer against demand spikes and supply delays.
Excel works for basic inventory management at a small scale, but it lacks the automation and integrations of dedicated software, and it raises the risk of inefficiency and human error as you add channels and locations.
A perpetual system updates inventory levels continuously as products are received, sold, and shipped. A periodic system updates levels at set intervals, typically after manual counts. Perpetual systems give more accurate, current data, while periodic systems are more prone to discrepancies.
The three categories are raw materials, work-in-progress (WIP) inventory, and finished goods.
Yes. Many inventory management systems, including Linnworks warehouse management, support barcode scanning. Scanners let you update stock levels, track products, and process orders quickly with fewer manual errors.
It updates stock levels automatically when returned items come back and tracks them through to resale, so your stock information stays accurate and returns are easier to manage.
Many systems integrate with POS software, so stock stays accurate whether a sale happens online or in a store. If you sell in person as well as online, check POS support before you choose.
Forecasting uses historical sales data and other factors to predict future demand. It helps you decide what to buy and when, reduces stockouts and overstocking, and improves profitability.
