Side-by-side comparison of 8 inventory tools - from free to enterprise. We cover pricing, AI features, purchase orders, and exactly which software fits your store size. Updated for 2026, including Stocky shutdown alternatives.
Shopify's native inventory tools handle the basics: stock tracking, simple transfers, and low stock alerts. For a store with fewer than 30 SKUs and one sales channel, that's usually sufficient.
But once you grow past 50 products, work with multiple suppliers, or experience seasonal demand swings, the gaps become expensive. Shopify doesn't calculate reorder points automatically. It doesn't predict when you'll run out. It doesn't tell you which products drive 80% of your revenue. And it doesn't flag dead stock until you notice it yourself.
These gaps cost real money. A single stockout on a product selling 20 units/day at $35 average order value costs you $700 per day in lost revenue. Over a two-week supplier lead time, that's $9,800. The right inventory software pays for itself many times over.
The question isn't whether you need inventory software - it's which type. The answer depends on your store size, sales channels, and the specific problem costing you the most right now.

Shopify's native inventory covers tracking, transfers between locations, basic purchase orders, and low stock alerts. It's the official Stocky replacement and works well for simple stores.
Debnix uses Google Gemini AI to analyze your Shopify sales data and predict stockouts before they happen. It auto-calculates reorder points from your actual sales velocity, runs ABC analysis on your catalog, manages purchase orders, and tracks profit margins per product.
Stockful positions itself as the closest Stocky replacement with a focus on inventory analytics and reporting. Clean UI, free tier available, and straightforward to set up.
Prediko offers AI forecasting trained on 25M+ SKUs with a 12-month inventory planning calendar. Strong PO workflows and designed specifically for direct-to-consumer Shopify brands.
One of the most mature inventory tools available. Deep purchase order workflows, multi-warehouse support, seasonal forecasting, and comprehensive reporting. Acquired by Sage in 2022.
Built around one core strength: keeping inventory synchronized across Shopify, Amazon, eBay, Etsy, and Walmart. If you sell on multiple platforms and overselling is your main problem, Sumtracker solves it.
Purpose-built for sellers who manufacture their own products. Raw material tracking, bills of materials, production scheduling, and shop floor management. The only option here built for makers.
Full ERP system combining inventory, POS, warehouse management, manufacturing, and accounting integrations. The most complete option - and the most expensive. Overkill for stores under $1M/year.

Shopify's Stocky app is shutting down on August 31, 2026. If you currently use Stocky for purchase orders, forecasting, or reporting, you need to migrate before that date. All Stocky data becomes inaccessible after shutdown.
For a detailed step-by-step walkthrough, read our Stocky migration guide. For a direct Stocky vs alternatives comparison, see the Stocky alternative page.
The Shopify App Store has over 1,000 inventory-related apps. Most are basic sync tools or stock counters. Here are the features that actually move the needle on your bottom line:
The software should calculate when to reorder based on your actual sales velocity and supplier lead times - not a static number you set manually. Manual thresholds break as sales patterns change.
Predicting future demand based on historical sales, seasonality, and trends. Even 70% accurate forecasting prevents the worst stockouts and overstock situations. Only 4 of the 8 tools here offer this.
Automatically classifying products by revenue contribution. Your top 20% of products generate ~80% of revenue - they deserve more safety stock and attention than the bottom 50%.
Going from "this product needs reordering" to "PO sent to supplier" in one workflow. The best tools auto-generate POs based on reorder points and let you email suppliers directly.
Revenue without margin data is flying blind. Track COGS per product to know which items are actually profitable - not just which sell the most. Read more on tracking profit margins.
Shopify's built-in inventory management is free with any Shopify plan. It covers stock tracking, basic purchase orders, transfers, and low stock alerts. For analytics specifically, Stockful has a free tier. Neither offers AI forecasting or reorder point calculation on the free plan.
Debnix at $21.99/month is the most affordable inventory software with AI-powered demand predictions for Shopify. The next cheapest AI option is Prediko starting at $49/month. Stockful offers basic analytics but not true AI forecasting.
For stores with fewer than 30-50 SKUs and steady demand, Shopify's built-in tools are usually sufficient. Once you hit 50+ SKUs, experience stockouts, or need demand forecasting, a dedicated app pays for itself by preventing lost sales. The cost of one stockout on a fast-moving product typically exceeds a month of app fees.
Shopify is directing merchants to use the built-in Shopify Admin tools, but these don't include Stocky's forecasting or advanced reporting. Third-party alternatives include Debnix (AI predictions, $21.99/mo), Stockful (analytics, free-$29/mo), and Prediko (forecasting, $49+/mo). Export your Stocky data before August 31, 2026.
Prices range from free (Shopify Admin, Stockful free tier) to $999+/month (Cin7 enterprise). Most mid-range options cost $20-$100/month. AI-powered tools start at $21.99/month (Debnix) and go up to $349/month (Prediko's highest tier). The right price depends on your SKU count, revenue, and which features you actually need.
Generally not recommended. Most inventory apps sync directly with Shopify and running two simultaneously can cause stock count conflicts and overselling. Choose one primary tool. You can run apps in parallel briefly for evaluation, but don't rely on both for live inventory data.
The most impactful features are: (1) automated reorder point calculation based on your actual sales data, (2) AI demand forecasting to predict stockouts, (3) ABC analysis to prioritize high-revenue products, (4) purchase order management, and (5) dead stock detection. Match your feature requirements to your store size and budget.
The "best" Shopify inventory software depends entirely on your store. A solo seller with 80 SKUs doesn't need Cin7. A manufacturer doesn't need Sumtracker. A multi-channel seller doesn't need Debnix.
Match the tool to your actual problem. If stockouts cost you sales, you need AI forecasting (Debnix, Prediko, or Inventory Planner). If overselling across channels is the issue, you need sync (Sumtracker). If you just need analytics, start free (Stockful).
And if you're on Stocky, don't wait until August. Start evaluating now, run your replacement in parallel, and switch well before the deadline. Your Q4 will thank you.
