10 Best Inventory Replenishment Software in 2025

You have a fast-growing e-commerce store. Sales are up and people simply can’t get enough of our products. But incorrectly predicting and replenishing your inventory is eating into your bottom lines and leading to missed sales opportunities, AGAIN! 

And while sales are surging, your quater on quarter profit margin is still stagnant.

You’re not alone though. We saw that this was the case with Jolie’s, Kate Hewko, Cloudsharks, until they replenish their inventory with Prediko - A story for another day. 

However, this is the reality for many scaling businesses. That’s why they often turn to dedicated inventory forecasting and replenishment software.

Let’s look at the top 10 inventory replenishment software that can bridge these gaps: 

Top Features to Look for in an Inventory Replenishment Software

Before diving into specific tools, let’s break down the key features you need to look for when choosing inventory replenishment software. These features will ensure that you have full control over your stock levels and help you make smarter decisions.

1. Real-time Inventory Tracking

You need accurate, up-to-minute data to avoid stockouts or overstocking. Look for software that syncs across all your sales channels—online, in-store, and even multiple warehouses. This way, you can track sales and monitor inventory in real time. Plus, you can set automatic reorder thresholds.

Why it’s important: Real-time tracking helps you make informed decisions, reducing costly errors.

2. Demand Forecasting

Another critical feature is demand forecasting. The ability to predict future demand based on historical sales data, market trends, and seasonality is a game-changer. By having accurate forecasts, you can ensure that your stock levels align with expected sales, preventing overstocking during slow periods and stockouts during peak demand times.

Look for replenishment software that uses AI-powered algorithms to analyze past sales patterns and provide more accurate demand predictions. The more sophisticated the forecasting, the more control you’ll have over your supply chain.

3. Multi-Location and Multi-Channel Support

If you’re running a business that sells on multiple channels (like Amazon, eBay, or your own Shopify store) or operates across multiple locations (different warehouses, retail stores, etc.), it’s essential that your inventory replenishment software can manage stock across all these locations seamlessly.

The right software lets you track stock levels at each warehouse or store, helping you avoid shortages and overstocking at any location.

4. Customizable Alerts and Notifications

The right replenishment software will notify you when stock levels are getting low, or when an item is approaching its reorder point. These alerts can help you avoid stockouts and ensure that you never miss a crucial reorder. 

Additionally, many systems let you customize notifications to fit your business’s unique needs—whether it’s an alert for a specific product, location, or sales threshold.

5. Easy Integration with Your Existing Systems

A siloed inventory replenishment software (like tabs and tabs of spreadsheets) will cause you to deal with a lot of duplicates and order discrepancies. Your replenishment software will need to work seamlessly with other systems you already use, such as your point-of-sale (POS), accounting software, and eCommerce platforms. 

Whether you’re using Shopify, WooCommerce, or any other platform, look for software with out-of-the-box integrations or easy API connections to ensure smooth data flow between systems.

Top 10 Inventory Replenishment Software Of 2025

Without a proper tool for demand forecasting and replenishment, companies can face several issues such as increased storage costs due to overstocking or missed sales opportunities due to stockouts.

It is crucial to choose the right software that helps with forecasting, management and visibility.

Do Remember…

When it comes to selecting the best inventory replenishment tool for your Shopify store, the key is to find a solution that aligns with your unique business needs, goals, and current setup.

Start by considering your store’s size and complexity. While tools like Prediko are ideal for larger, more complex stores, solutions like Genie are well-suited for smaller businesses with simpler inventory needs.

Also, your platform should easily integrate with Klaviyo, QuickBooks and the likes. Real-time tracking and alert systems are also essential to keep you on top of stock levels and avoid costly stockouts.

We do observe that many e-commerce businesses won’t have large IT teams that can suppose onboarding and setup. Your platform of choice should be easy to  set up or offer a white-glove approach in setup, migration and onboarding.

Choose the solution that fits seamlessly into your operations, and you'll set your store up for success.
