10 Best Inventory Management Apps for Shopify (2026 Edition)

Let me be honest with you managing inventory on Shopify without a dedicated app is like trying to run a shop blindfolded. You don’t know what’s running low, what’s been sitting unsold for months, or what’s about to go out of stock right in the middle of your biggest sale. It’s stressful, and it costs you money.

The good news? There are some really solid inventory management apps built specifically for Shopify that make all of this so much easier. And in this post, I’m going to walk you through the 10 best ones so you can pick the right fit for your store.

Let’s get into it.

Why You Even Need an Inventory Management App

Before we get to the list, let me quickly explain why Shopify’s built-in tools aren’t always enough.

Shopify does give you basic inventory tracking you can see stock quantities, set low stock alerts, and manage transfers between locations. That’s fine when you’re starting out. But once you’re selling on multiple channels, managing dozens or hundreds of SKUs, or trying to forecast demand, those built in tools hit a wall pretty fast.

And here’s something important Shopify retired its free Stocky app in February 2026, with a complete shutdown scheduled for August 2026. Stocky gave merchants basic inventory analytics, demand forecasting, and purchase order management at no extra cost. So if you were relying on that, it’s time to find an alternative.

Research shows that 69% of customers will shop with a competitor if their preferred product is out of stock. That single stat should tell you everything. Getting your inventory right isn’t optional it’s survival.

1. Prediko Best Overall

If I had to recommend just one app for most Shopify merchants, it would be Prediko. It’s built specifically for Shopify D2C brands and it goes way beyond basic stock tracking.

What makes Prediko stand out is the AI driven demand forecasting. It predicts demand at SKU, category, and company levels to help you make smarter purchasing decisions, and it gives you automated out of tock alerts and intelligent buying recommendations to optimize stock levels.

You also get purchase order management you can create, track, and bulk edit POs all in one place. And the reporting is genuinely useful, with over 100 filters available so you can slice the data however you need.

Prediko is best for brands of all sizes especially in fashion and apparel, beauty, retail, manufacturing, and CPG.

One more thing it even handles subscription based stores, which is rare. If your Shopify store runs subscriptions, Prediko can forecast demand for those too.

Pricing: Paid plans starting around $49/month with a free trial available.

2. Stock Sync Best for Multi Source Inventory

Got inventory coming from multiple suppliers, spreadsheets, or platforms? Stock Sync is your solution.

Stock Sync is ideal for syncing inventory across multiple sources and formats like CSV, XML, and Google Sheets, with automation and ease of use.

The way it works is simple. You connect your different inventory sources whether that’s a supplier feed, a Google Sheet, or an FTP server and Stock Sync keeps everything updated automatically. No more manually uploading spreadsheets or fixing mismatched numbers.

It integrates with Google Sheets, FTP, API, and Shopify Flow and supports multiple languages including English, Japanese, Chinese variants, German, French, Polish, Dutch, and Spanish.

If your business works with multiple vendors and you’re spending way too much time reconciling inventory data, this app will save you hours every week.

Pricing: Free plan available. Paid plans start from $5/month.

3. Katana ERP Best for Manufacturers

If you’re not just selling products but actually making them, Katana is the one to look at.

Katana is the ideal solution if you’re manufacturing your own products and need real time production tracking, smart forecasting, and native Shopify integration all without complicated setups.

It handles raw materials tracking, production planning, and finished goods inventory all in one visual dashboard. You can see exactly what you need to produce, what materials you have, and where your orders are in the production process.

Katana offers visual production planning that helps streamline your production and order fulfillment processes. With real-time inventory sync, it ensures that your stock levels and orders are always up to date.

The one thing to keep in mind is the pricing. Katana’s Starter plan is $199/month, the Standard plan is $399/month, the Professional plan is $899/month, and the Professional Plus plan is $1,999/month. So this is a serious tool for serious manufacturing operations, not a casual pick for small stores.

Pricing: Starts at $199/month.

4. SKULabs Best for Multi Channel Fulfillment

If you’re selling on Shopify, Amazon, eBay, Etsy, and maybe a few other places all at once, keeping your inventory straight can feel impossible. SKULabs is built exactly for this situation.

SKULabs offers a comprehensive solution for merchants selling on multiple channels. With features like barcode scanning and multi channel synchronization, SKULabs ensures that inventory is tracked and orders are fulfilled accurately, improving operational efficiency.

You get everything in one place orders from every channel, inventory updates pushed everywhere, and shipping label generation. It’s a proper warehouse management setup for brands that have grown beyond a single storefront.

The barcode scanning feature is especially handy if you’re doing any kind of in house fulfillment and want to reduce picking errors.

Pricing: Starts from $299/month for growing operations.

5. Cin7 Core Best for Combined Inventory and Sales

Cin7 Core (formerly DEAR Inventory) is a full featured inventory and business management platform that goes deep on features.

Cin7 Core is good for combined inventory, manufacturing, and multi channel sales management.

It covers purchase orders, sales orders, production management, and multi channel inventory sync under one roof. If you’re operating a business that has both wholesale and retail sides, Cin7 handles that combination really well.

One important heads up though after the Sage acquisition, pricing moved to a custom quote model starting around $245/month, and several users have reported significant price increases. There have also been reports of technical issues with Shopify API synchronization through late 2024 and into 2025, so it is worth testing thoroughly during the free trial period.

It’s still a powerful tool, just make sure you test it properly before committing.

Pricing: Custom pricing, starting around $245/month.

6. Assisty Best for Data Driven Merchants

If you love data and want your inventory decisions backed by real numbers, Assisty is worth a serious look.

Assisty is purpose built for Shopify, using your real-time store data to create actionable insights. What makes it stand out is its focus on simplicity, flexibility, and smart automation.

The app gives you product analytics so you can identify your bestsellers, your slow movers, and the dead stock that’s just sitting there eating up your cash. It also gives you automated reports on a schedule so you’re not digging for information, it just comes to you.

A skincare brand with fast moving hero products can use sales velocity insights to prevent stockouts. A fashion retailer managing multiple suppliers can track vendor performance and make better purchasing decisions. And a home decor brand preparing for the holiday season can analyze last year’s trends to stock this year’s collections accurately.

If data is how you make decisions, Assisty makes that a lot easier.

Pricing: Free plan available. Paid plans from $9/month.

7. EasyScan SKU & Barcode Best for Barcode Based Operations

Sometimes you don’t need a massive platform. You just need a reliable way to scan barcodes, create purchase orders, and keep your warehouse organized. That’s exactly what EasyScan does.

EasyScan SKU & Barcode has 326 reviews with a 5.0 rating on the Shopify App Store and it helps you create purchase orders and streamline inventory management.

It’s a “Built for Shopify” app, which means Shopify has verified that it meets their highest standards for performance, design, and integration. That badge matters it means the app is reliable and won’t break things on your store.

This is a great pick for smaller to mid size stores that are doing in-house fulfillment and need barcode scanning without paying for a massive enterprise platform.

Pricing: Free trial available. Plans start from around $9.99/month.

8. Stockie Inventory Management Best for Forecasting on a Budget

Stockie is a newer app that’s been building a solid reputation fast. It currently holds a 5.0 rating on the Shopify App Store, which is hard to maintain, and it’s also “Built for Shopify” certified.

Stockie Inventory Management offers low stock alerts and inventory forecasting to help you restock on time.

It’s simpler than some of the heavier platforms on this list, but that’s honestly a feature for a lot of store owners. You don’t always need 200 filters and a complex dashboard. Sometimes you just want to know what’s running low and when you need to reorder and Stockie does that cleanly.

If you’re an early stage or growing brand that wants smart forecasting without the enterprise price tag, Stockie is worth trying.

Pricing: Free trial available.

9. Simple Inventory Best for CSV Based Updates

Sometimes the most straightforward solution is the best one. Simple Inventory is exactly what it sounds like a no nonsense app that lets you manage your inventory through CSV files.

Simple Inventory lets you update inventory counts, tags, prices, and more by uploading a CSV file, simplifying what could otherwise be a complex task. You can also set the app to periodically fetch your inventory CSV file from a designated URL or SFTP server, keeping your stock levels accurate at all times.

You also get bulk tag management and out of stock prevention built in.

This is perfect if you’re working with a supplier who sends you regular inventory feeds in spreadsheet format and you want to automate those updates without building a custom integration.

Pricing: Free plan available.

10. Restock Rocket Best for Back in Stock Alerts

Here’s one that a lot of merchants overlook. Restock Rocket isn’t a traditional inventory management tool it focuses on a very specific and very valuable problem: letting your customers know when a product is back in stock.

With Restock Rocket, you can send back in stock emails, SMS, and push notifications when a previously unavailable item is restocked in your Shopify store. It also allows you to design the ‘Notify me’ button and alert messages to match your store’s brand.

Pricing: Free plan available. Paid plans from around $10/month.

How to Pick the Right One for Your Store

Okay, so now you’ve seen all 10. The question is which one is right for you?

Here’s a simple way to think about it:

You’re a manufacturer making your own products → Go with Katana. It’s built for production tracking and raw materials management.

You’re selling on 3+ channels → SKULabs or Stock Sync will keep everything in sync without you losing your mind.

You want AI forecasting and smart replenishment → Prediko is your best bet. It’s the most advanced option for Shopify-focused brands.

You just want clean data and good reports → Assisty is the move.

You’re on a tight budget but need forecasting → Try Stockie. It’s solid and affordable.

You work with supplier CSV feeds → Simple Inventory handles that without any fuss.

You lose sales when products go out of stock → Add Restock Rocket regardless of which other app you use. It works alongside everything else.

One Last Thing

Here’s the real talk the best inventory management app is the one you’ll actually use consistently. A complex enterprise platform sitting half-configured doesn’t help anyone.

Start with what your business actually needs right now. If you’re growing fast, invest in something with AI forecasting like Prediko. If you’re still figuring things out, start simple and upgrade as you scale.

Poor inventory management costs retailers an estimated $1.6 trillion globally every year. That’s not a number to ignore. But you don’t need to spend a fortune to fix it — you just need the right tool for where your business is today.

Pick one from this list, install it, and actually use it. Your stock levels, your cash flow, and your customers will all thank you .
