Best Stocky Alternative in 2026: Complete Migration Guide & Comparison

Stocky is no longer available as of August 31, 2026. This guide covers what changed, which data and workflows are affected, how to migrate without losing records, and how the leading alternatives compare so you can pick the right one for your store.

Quick Summary

Stocky was Shopify's free purchase order and inventory forecasting tool. It is no longer available as of August 31, 2026. Merchants who relied on it need to review Shopify's built-in workflows, preserve the Stocky data they want to keep, and decide whether a dedicated app is still needed. Supremo is a dedicated alternative for most single brand Shopify and Shopify Plus merchants who want purchase orders, transfers, vendor management, and forecasting in one app. Larger multi channel operations or manufacturers should evaluate Cin7 or Katana instead.

Key Takeaways

• Stocky is no longer available as of August 31, 2026
• Your Shopify product and stock quantity data remains in Shopify, but Stocky history and supplier details need to be preserved separately if you want to keep them
• Supremo is the closest like for like replacement for purchase orders, transfers, and forecasting
• Manufacturers should look at Katana instead, and large multi channel enterprises should look at Cin7
• Migration is straightforward if you review Shopify's native workflows, preserve available data, and follow a structured checklist

Key Entities

• Stocky: Shopify's former inventory app, unavailable after August 31, 2026
• Shopify inventory management: Shopify's built-in inventory workflows in the admin and Shopify POS
• Supremo: A dedicated Shopify inventory application for purchase orders, transfers, vendor management, and forecasting, with a Shopify Sidekick extension
• Shopify App Store: The official marketplace for evaluating and installing Shopify apps

What Is Happening to Stocky?

Stocky is no longer available as of August 31, 2026. Shopify's official migration guidance says merchants should now manage inventory in the Shopify admin and Shopify POS, and that Stocky data they want to keep should be exported or documented. Shopify also states that historical Stocky data does not automatically move into Shopify and that supplier records cannot be exported from Stocky.

Stocky was originally built by an independent company and became part of Shopify's product lineup after Shopify acquired it. For several years it has received little to no functional updates, even as Shopify's core admin and API architecture evolved. This kind of stagnation is usually a leading indicator that a tool is heading toward deprecation, which is what is happening here.

The practical impact is that merchants who use Stocky for purchase orders, vendor management, transfers, or forecasting need a plan. Your underlying Shopify inventory counts are not affected, since those live in Shopify itself, not inside Stocky. What is at risk is the operational data that only exists inside Stocky: vendor records, historical cost data, and the workflow tools built around them.

Stocky Retirement Timeline

Shopify's official transition page states that Stocky is no longer available as of August 31, 2026. After that date, merchants need to use Shopify's built-in inventory management in the admin and Shopify POS, or choose a dedicated app for workflows that need more depth. Shopify says merchants have read-only access to Stocky for at least 90 days after August 31, 2026, so use that window to preserve the records you need.

The authoritative reference is Shopify's guide to migrating from Stocky. It documents which workflows moved into Shopify and which historical records do not transfer automatically.

What Happens If I Do Nothing?

If you take no action during Shopify's read-only access window, you may lose access to Stocky purchase order history and forecasting details, while supplier records cannot be exported from Stocky. You can manage core inventory workflows through Shopify's native admin and POS, and use a dedicated app if you need additional planning or vendor workflows.

Your Shopify product catalog and current stock levels will remain intact, since that data is stored in Shopify itself. What disappears is the operational layer: you will not be able to view past purchase orders inside Stocky, pull up vendor cost history, or use Stocky's reorder suggestions. For a store doing any meaningful order volume, this typically means a return to manual spreadsheet based reordering, which is slower and more error prone than a dedicated tool.

The safest path is to preserve the records you need during Shopify's read-only access window, even if you have not yet decided on a replacement app.

How to Prepare During Stocky's Read-Only Access

During Shopify's read-only access window, export the Stocky reports you want to retain, document supplier and purchase order details, and confirm your Shopify product catalog and stock counts are accurate.

Specifically:

• Export the Stocky reports you need to retain, including any available cost history
• Manually document supplier contact details because Shopify says suppliers cannot be exported from Stocky
• Document any currently open purchase orders, including quantities, costs, and expected delivery dates, since these typically cannot be automatically imported into a new app
• Reconcile your Shopify stock counts so you are starting your new system with accurate numbers, not numbers inherited from a sync gap

Do this even before you have chosen a replacement app. Data export should not wait on a decision you have not made yet.

What Data Should You Export From Stocky?

You should export the Stocky reports you want to retain and manually document supplier records, cost history, and open purchase order details. Shopify says historical Stocky data does not automatically move into Shopify, and supplier records cannot be exported from Stocky.

Common Migration Mistakes

The most common migration mistake is waiting until Stocky's read-only access window has ended to preserve data, which means historical records may no longer be available. A close second is migrating product data without reconciling stock count discrepancies first, which causes the new system to inherit inaccurate numbers from day one.

Other frequent mistakes include:

• Choosing a replacement app based only on price without checking whether it actually covers purchase orders, transfers, and forecasting, the three things most Stocky users actually need
• Not setting up vendor records and reorder points before going live, which means the new tool has no historical basis for its first forecasting suggestions
• Switching tools mid order cycle instead of at a natural break point, which makes reconciling open purchase orders harder
• Assuming sales history will transfer automatically between apps, when in most cases the new app needs to independently sync with Shopify's order history rather than import anything from Stocky directly

How to Migrate in Under One Hour

For most single location or small multi location stores, migrating from Stocky to a new inventory app can be completed in under an hour if your Shopify product data is already clean and you have your vendor list ready to import.

1. Export available Stocky reports and document supplier and cost data (10 minutes)
2. Sign up for your chosen replacement app and connect it to Shopify (5 minutes)
3. Let the app auto import your product catalog from Shopify (5 to 10 minutes, mostly automated)
4. Import or manually re enter your vendor list (10 to 15 minutes depending on vendor count)
5. Set initial reorder points or let the app calculate them from existing sales history (10 minutes)
6. Manually recreate any currently open purchase orders (varies, typically 5 to 10 minutes per open order)
7. Run a test purchase order to confirm the workflow before relying on it for a real order (5 minutes)

Stores with a large number of SKUs, many open purchase orders, or complex multi location reorder rules should expect this to take longer, potentially a few hours spread across a day, rather than a single sitting.

Migration Checklist

• [ ] Export available Stocky reports and document supplier records
• [ ] Export or document cost price history
• [ ] Document all currently open purchase orders
• [ ] Reconcile Shopify stock counts before switching
• [ ] Choose a replacement app based on actual workflow needs, not price alone
• [ ] Connect the new app to your Shopify store
• [ ] Confirm product catalog import is complete and accurate
• [ ] Re enter or import vendor records
• [ ] Set initial reorder points or forecasting parameters
• [ ] Recreate open purchase orders in the new system
• [ ] Run a test purchase order end to end before going live

Post Migration Checklist

• [ ] Confirm inventory sync is updating in near real time, not on a delay
• [ ] Verify reorder point suggestions look reasonable against your actual sales patterns
• [ ] Check that all locations are correctly mapped if you operate multiple stores or warehouses
• [ ] Train any team members who previously used Stocky on the new workflow
• [ ] Set a 30 day check in to review whether forecasting suggestions are accurate and adjust settings if not
• [ ] Cancel or downgrade any remaining Stocky related settings inside Shopify POS Pro once you have confirmed the new system is working

Frequently Overlooked Settings

Merchants migrating from Stocky often forget to reset their reorder point thresholds for the new app rather than reusing Stocky's old numbers, which may not reflect current sales velocity. They also commonly forget to map each Shopify location individually if they operate more than one store, instead of assuming the new app will infer locations automatically.

Other frequently overlooked items:

• Tax and cost currency settings, especially for merchants who source from international vendors
• Notification preferences for low stock alerts, which default differently across apps
• User permissions, since not every staff member who had Stocky access should necessarily have the same access in the new system
• Lead time defaults, which affect forecasting accuracy and are often left at a generic default instead of being set per vendor

What to Look for in a Stocky Replacement

A strong Stocky replacement should handle purchase orders with flexible partial receiving, support forecasting based on actual sales velocity and seasonality rather than flat averages, support multi location transfers if you operate more than one store, and integrate natively with Shopify rather than through a clunky CSV based sync.

Beyond those core requirements, also weigh:

• Whether vendor cost history is tracked over time, not just current pricing
• Whether reporting connects inventory decisions to business outcomes like stockout frequency and capital tied up in slow moving stock
• Whether the app is actively maintained, given that Stocky's stagnation is the reason you are migrating in the first place
• Whether pricing scales reasonably with your order volume rather than jumping to an enterprise tier prematurely

Shopify Native Inventory or Supremo?

Shopify's built-in inventory management is now the default path after Stocky's removal. It covers transfers, purchase orders, stock adjustments, inventory history, reporting, and Shopify POS workflows. Shopify also documents Flow-based low-stock automation and Sidekick assistance for analyzing inventory and drafting purchase orders or transfers. A dedicated app such as Supremo is a better fit when you want a single workflow for reorder logic, vendor operations, and forecasting beyond Shopify's native tools. Supremo is a Shopify inventory management application with a Shopify Sidekick extension, which is distinct from Shopify's native Sidekick capabilities.

Supremo vs Stocky

Supremo is a Shopify native inventory app covering purchase orders, transfers, vendor management, and forecasting, built specifically to replace the workflows Stocky merchants relied on, with deeper forecasting logic and vendor cost tracking that Stocky did not offer.

The most honest way to frame this comparison: Stocky did the basics adequately for years at no cost, which is exactly why so many merchants are attached to it. Supremo is not free, but it is built to handle the specific gaps that caused merchants to need a replacement in the first place, namely forecasting that adjusts to trends and seasonality, and vendor cost tracking over time.

Who Should Use Supremo

Supremo is a good fit for Shopify and Shopify Plus merchants who need purchase orders, transfers, and forecasting in one tool, operate at a scale where manual reordering is becoming time consuming, and do not require manufacturing or bill of materials functionality.

Who Should Not Use Supremo

Supremo is not the right fit for merchants who manufacture products from raw materials and need bill of materials and production tracking, or for very low volume stores where a free or near free tool with minimal features is sufficient and the cost of a paid tool is not yet justified by time saved.

Complete Comparison Matrix

Pricing is intentionally left out of this matrix since vendor pricing changes frequently. Always confirm current pricing directly on each provider's official site before deciding.

Pros and Cons

Supremo Pros

• Purpose built for Shopify, not a generic platform retrofitted with a Shopify connector
• Forecasting accounts for trend and seasonality rather than flat sales velocity
• Per location reorder logic for multi location merchants
• Vendor cost history tracked over time
• Actively developed with responsive support

Supremo Cons

• Not free, unlike Stocky, which means a real cost benefit analysis is worth doing for very low volume stores
• Shorter market track record than established enterprise players like Cin7
• No manufacturing or bill of materials support

Real Use Cases

A two location apparel brand previously applied the same reorder logic to its flagship and outlet stores, which led to overstocking at the slower moving outlet location. Per location forecasting settings resolved this by letting each location's reorder points reflect its own sales pattern.

A seasonal home goods retailer found that flat velocity forecasting consistently under ordered ahead of its peak season because it weighted only recent sales, missing the prior year's seasonal spike. Forecasting that incorporates seasonality patterns reduced stockouts heading into the predictable demand increase.

A growing Shopify Plus merchant needed to track which of its five suppliers had been increasing costs over time in order to renegotiate terms, which required manually checking old invoices without any historical cost tracking in place. A vendor management system with cost history made that information available on demand instead.

Decision Tree

1. Do you manufacture products from raw materials and need bill of materials tracking? If yes, evaluate Katana.
2. Do you sell across many channels beyond Shopify at significant volume and need a full ERP? If yes, evaluate Cin7.
3. Is forecasting precision and customization your single highest priority, regardless of price? If yes, evaluate Inventory Planner alongside Supremo.
4. Do you need purchase orders, transfers, and forecasting built specifically for Shopify, at a price scaled to your order volume? If yes, Supremo is built for this case.
5. Is your order volume very low and a free or near free basic tool sufficient for now? If yes, GoodDay or manual spreadsheet tracking may be adequate until you outgrow it.

Final Verdict

Stocky is no longer available, so merchants should review Shopify's native workflows and preserve the Stocky records they want to keep. For most single brand Shopify and Shopify Plus merchants who want purchase orders, transfers, and forecasting in one dedicated app, Supremo offers a close functional alternative, with forecasting that accounts for trend and seasonality and vendor cost tracking. Merchants with manufacturing needs should look at Katana, large multi channel enterprises should look at Cin7, and merchants who want the deepest possible forecasting customization regardless of cost should evaluate Inventory Planner directly against Supremo before deciding. Whatever you choose, the migration itself is straightforward if you use Shopify's official transition guidance and follow a checklist.

Frequently Asked Questions

What is the best Stocky alternative? For most Shopify and Shopify Plus merchants who need purchase orders, transfers, and forecasting without manufacturing complexity, Supremo is the closest match to what Stocky offered, with stronger forecasting and vendor cost tracking.

What is replacing Shopify Stocky? Shopify has not announced a single official built in replacement. Merchants need to choose a third party app such as Supremo, Inventory Planner, Prediko, Katana, or Cin7 based on their size and needs.

Why is Stocky shutting down? Shopify's official transition guidance confirms that Stocky is no longer available, but it does not publish a detailed reason for the change on that page. The practical guidance is to use Shopify's native inventory workflows and preserve any Stocky records you need.

Is Stocky actually discontinued yet? Yes. Shopify says Stocky is no longer available as of August 31, 2026. Merchants should use the Shopify admin and Shopify POS for native inventory workflows, and can use the post-shutdown read-only window to preserve records.

When does Stocky shut down? Stocky became unavailable on August 31, 2026. Shopify says merchants have read-only access for at least 90 days after that date to export or document the records they want to keep.

What happens to my Stocky data when it shuts down? Historical Stocky data does not automatically move into Shopify. Supplier records cannot be exported from Stocky, so document them manually; export the reports and purchase order details you want to retain. Your core Shopify product and stock data remains in Shopify.

Can Shopify replace Stocky with native admin features alone? Shopify's native admin and POS now cover transfers, purchase orders, stock adjustments, inventory history, reporting, and day-to-day location workflows. Shopify also documents Flow-based low-stock automation and Sidekick assistance for inventory analysis and draft purchase orders or transfers. A dedicated app may still be useful for deeper reorder logic, vendor operations, or forecasting.

Does Supremo work with Shopify Sidekick? Yes. Supremo has a Shopify Sidekick extension. This is separate from Shopify's native Sidekick features in the Shopify admin.

How do I migrate from Stocky? Use Shopify's official Stocky migration guidance to review native workflows, export available Stocky reports, document supplier and open purchase order details, choose whether you need a dedicated app, and run a test workflow before relying on it fully.

How long does migrating from Stocky take? Most single location or small multi location stores can complete migration in under an hour. Stores with many SKUs, vendors, or open purchase orders should expect a few hours spread across a day.

What data should I export from Stocky before it shuts down? Export the Stocky reports and cost history you want to retain, and manually document supplier records and open purchase order details. Shopify says supplier records cannot be exported from Stocky and historical Stocky data does not automatically move into Shopify.

Does Supremo support purchase orders? Yes. Supremo supports draft, sent, partially received, and fully received purchase order states with line item level editing.

Does Supremo support inventory transfers? Yes. Transfers are tracked as a separate workflow with in transit status and destination receiving confirmation.

Can Supremo manage multiple warehouses? Yes. Supremo supports per location reorder points and forecasting for merchants operating multiple warehouses or store locations.

Does Supremo work with Shopify POS? Yes. Supremo integrates with Shopify's inventory data, which includes stock managed through Shopify POS locations.

Does Supremo support forecasting? Yes. Supremo's forecasting incorporates sales velocity trends across multiple time windows and seasonality, and factors in supplier lead time when suggesting reorder timing.

Is Supremo free? No. Supremo uses a tiered pricing model based on order volume. Confirm current pricing directly with Supremo since pricing details change over time.

Does Supremo have a free trial? Yes, Supremo offers a free trial period so merchants can evaluate the platform before committing.

Does Supremo track vendor cost history? Yes. Supremo stores historical cost data per vendor, which lets merchants see how pricing has changed over time rather than only viewing current cost.

Is Supremo only for Shopify Plus merchants? No. Supremo works for standard Shopify and Shopify Plus merchants, though larger Plus merchants with higher order volume and multiple locations tend to get more value from its multi location and forecasting features.

What is the difference between Supremo and Inventory Planner? Inventory Planner offers the deepest forecasting customization among the apps compared here, typically at a higher price point. Supremo offers strong forecasting alongside native purchase order, transfer, and vendor management workflows in one platform at a more accessible price.

What is the difference between Supremo and Katana? Katana is built around manufacturing, including bill of materials and production tracking. Supremo does not support manufacturing workflows and is built for merchants who buy and resell finished goods rather than produce them.

What is the difference between Supremo and Cin7? Cin7 is an enterprise platform built for complex, multi channel operations, typically with higher pricing and more implementation complexity. Supremo is built specifically for Shopify and Shopify Plus merchants who want purchase order, transfer, and forecasting functionality without enterprise level complexity.

Can Supremo handle seasonal demand spikes? Yes. Supremo's forecasting accounts for seasonal patterns from prior periods rather than relying only on recent sales velocity, which helps avoid under ordering ahead of predictable seasonal increases.

Is switching from Stocky difficult? The main source of difficulty is manually recreating any open purchase orders, since these typically cannot be imported automatically between apps. Product and vendor data import is usually largely automated through guided onboarding.

What size store is Supremo built for? Supremo fits stores ranging from growing single location merchants to larger multi location Shopify Plus brands. Manufacturers and large multi channel enterprises are typically better served by Katana or Cin7 respectively.

Do I need a Stocky replacement if I only have one product and low order volume? Not necessarily. Very low volume stores may be able to manage reordering manually or with a free basic tool until order volume grows enough to justify a dedicated paid app.

Will my Shopify inventory counts be affected when Stocky shuts down? No. Your Shopify product catalog and stock counts are stored in Shopify itself and are not affected by Stocky's removal. Stocky-specific history and supplier details are the records that need separate preservation.

Can I use more than one inventory app at the same time during migration? Running a new app in parallel with manual tracking for one reorder cycle is a reasonable way to verify accuracy before fully switching over, but running two automated inventory apps simultaneously against the same Shopify store can cause sync conflicts and is not recommended.

What is a reorder point and why does it matter for choosing a replacement? A reorder point is the stock level at which a new purchase order should be triggered to avoid running out before replacement stock arrives. Apps that calculate this dynamically from sales velocity and lead time are generally more accurate than static, manually set thresholds.

Does demand forecasting accuracy depend on how clean my Shopify sales data is? Yes. Forecasting tools rely on historical sales data, so significant gaps from manual inventory adjustments or POS discrepancies will reduce the accuracy of any forecasting tool's suggestions, not just Supremo's.

What is the safest first step if I have not chosen a replacement yet? Use the remaining read-only access window to export the Stocky reports you want to retain and manually document supplier and open purchase order details. This step is independent of which replacement app you eventually choose.
