Stocky Shut Down: Best Alternatives (2026)

Stocky is dead. Not dying. Dead.

Here is the short version if you just want the answer. Shopify retired Stocky on August 31, 2026, and the replacement we recommend is ReplenishRadar: statistical forecasting you can inspect, purchase orders, and native Amazon FBA support, from $99/mo. Under about 30 SKUs, spreadsheets or the built-in Shopify Admin still work. Inventory Planner, Prediko and Stockful are described below for what they are built for and where they differ from us. The rest of this post is the reasoning behind that recommendation, and the full ReplenishRadar vs Stocky comparison if you want the side-by-side.

Shopify pulled it from the App Store on February 2, 2026. Transfers and min/max forecasting were already stripped out in July 2025. The app stopped working entirely on August 31, 2026. If you are reading this, you probably already know all of that and you are here for the "now what" part.

Sellers who built their entire reorder workflow around Stocky now need a replacement, and the deadline is behind them.

Answer one question first: do you sell anywhere other than Shopify?

It is the only fork on this page that is expensive to get wrong. Stocky was Shopify-only, so it never forced you to think about it, and most of the tools being recommended as replacements are Shopify-only too. Pick one of those while an Amazon or wholesale channel is anywhere in your plans and you will be running a second system for it inside a year, which is how sellers end up with a spreadsheet stitching two tools together. That was the problem Stocky users had before Stocky was even in trouble.

If you sell on Shopify and Amazon, or expect to: ReplenishRadar, from $99/mo. That is us, and combined forecasting across both channels is the reason we are on this list at all.

If you are Shopify-only, ReplenishRadar still fits from about 50 products: forecasts you can inspect, lead times measured from your PO history, and Amazon covered the day you add it. Other Shopify-only apps exist (Stockful from $19.99/mo, Monocle from $47/mo, Prediko from $49/mo priced on GMV, and Inventory Planner by Sage, quote-based since 2026), and each is described below. Under 30 SKUs and one supplier, a spreadsheet works, honestly.

If your problem is bigger than Stocky was: Cin7 ($349/mo) or Katana (free to 30 SKUs, then a custom annual quote) cover wholesale, manufacturing or accounting alongside inventory, and we do not. Starshipit WMS or similar cover pick, pack and barcode operations.

The rest of this is the detail behind each of those, the migration checklist, and what we would do in your position.

The Shutdown Timeline

Date	What Happened
Jul 7, 2025	Features removed: transfers, min/max forecasting, barcode printing
Feb 2, 2026	Delisted from Shopify App Store. No new installs.
Aug 31, 2026	Complete shutdown. Velocity-based reorder suggestions and purchase orders stop with the rest of the app.

The first row is the one most sellers missed. Transfers and min/max forecasting went in July 2025, more than a year before the shutdown. The velocity-based reorder suggestions and purchase orders kept running until August 31, 2026, and went with everything else.

Why Shopify Killed Stocky

Shopify has not said why, so this is our read, not a statement from Shopify. Stocky started as a third-party app that Shopify acquired. Shopify folded basic inventory features into the Admin over time, and Stocky became an orphan. No dedicated team. No roadmap. Feature removals started quietly, then the delisting made it official.

Shopify's stated replacement is the built-in Admin inventory management. It handles stock counts and location transfers. That is about it. No demand forecasting. No reorder suggestions. No purchase order workflows. If your entire Stocky usage was "check how many units I have," the Admin works fine. If you were using Stocky for reorder planning, the Admin is not a replacement. It is a downgrade.

Your Actual Options

These are grouped by the decision you are actually making. "Closest to Stocky" is a tempting way to sort a list like this and it is the wrong one: Stocky was Shopify-only and deliberately simple, so sorting on similarity to it just rewards whichever tool is smallest. The question worth answering is which of these still fits you in two years, and we start with ours below.

Our recommendation: ReplenishRadar

Cost: $99-$499/month depending on SKUs and stores, month to month. 14-day free trial.

This is our tool, so take that into account. We built ReplenishRadar for Shopify and Amazon sellers who need demand forecasting, reorder recommendations, and purchase order workflows. The exact things Stocky used to do, but with actual statistical forecasting instead of simple recent-velocity math.

Where it goes further than Stocky ever did: demand forecasting with trend and seasonality detection, safety stock calculations that factor in lead time variability, reorder point automation, FBA restocking for sellers who also sell on Amazon, and supplier management with lead time tracking.

If you are Shopify-only today, you get forecasts you can inspect and lead times measured from your own PO history, and Amazon is there the day you add it. If you sell on both Shopify and Amazon, Stocky was never going to work for you anyway (it was Shopify-only). ReplenishRadar handles both channels from one place.

Migration from Stocky starts with a Shopify OAuth connection, which takes about five minutes; your catalog and sales history then sync automatically, usually finishing within a few hours. Supplier data imports through the supplier CSV flow, and open or historical POs import through the purchase-order CSV flow with preview before confirm. The PO import preserves PO numbers and received quantities for history, but it does not move stock. Start the 14-day trial.

If you are not sure you need a tool at all

Spreadsheets

Cost: Free (plus your time).

A spreadsheet is the obvious fallback after losing a tool. A Google Sheet with your SKUs, current stock, average daily sales, and a simple reorder point formula. It works.

The problem is maintenance. Illustrative assumptions: say each SKU takes about 40 seconds to update by hand. At 30 SKUs, the weekly update is 20 minutes. At 200 SKUs, it is over two hours. At 500, you stop doing it consistently and start flying blind on the SKUs you did not get to this week. The spreadsheet does not pull your sales data automatically. It does not adjust when lead times shift. It does not warn you that SKU #347 has six days of stock left.

That gap is where the money leaks. Research by Corsten and Gruen, published in Harvard Business Review, found that 21% to 43% of shoppers who hit a stockout buy from a competitor instead. Missing one reorder on one fast mover is not a rounding error. It is a customer you handed to someone else.

If you have under 30 SKUs and one supplier, a spreadsheet is fine. Past that, the time cost exceeds what you would spend on software.

Shopify Admin (do nothing)

Cost: Free (included with Shopify).

Shopify's built-in inventory tracks quantities across locations and handles basic transfers. That is the floor, not the ceiling. There is no forecasting, no reorder point calculation, no purchase order generation.

This works if inventory planning is not really your problem. Maybe you sell 10 SKUs. Maybe you order once a month from one supplier and eyeball it. For that workflow, Shopify Admin is fine and always has been.

For anyone who was actively using Stocky's reorder suggestions, this is not a substitute.

Shopify-only replacements

These are the like-for-like swaps. Every one of them stops at the Shopify boundary, which is the thing to check against your own plans before you commit.

Stockful

Cost: $19.99/mo (2,000 SKUs, 1 location), $39.99/mo (7,500 SKUs, 5 locations), $79.99/mo (15,000 SKUs, 10 locations). Overages run $5 per extra 500 SKUs or per extra location. 14-day trial.

Stockful covers the reporting side of Stocky closely: daily inventory snapshots going back up to two years, self-tuning demand forecasts with safety stock, reorder points, scheduled reports and Slack alerts. It launched in March 2026, which is to say it was built for this migration.

We have not run it on a real catalogue, so treat this as a description from its own materials rather than a review. Two things are worth knowing before you commit. It is Shopify-only, so the day you add Amazon you are shopping again. And it is priced per SKU and per location rather than on revenue, which is the friendlier shape if you are growing sales faster than catalogue.

Its ceiling is the Shopify boundary, so check that against your plans.

Inventory Planner

Cost: Quote-based since 2026.

Inventory Planner is a well-established Shopify app with detailed forecasting and replenishment features. It handles large catalogs and gives you granular control over forecasting parameters per product. If you have 500+ SKUs on Shopify and want to tune every knob, Inventory Planner has the depth for it.

That depth comes with a lot of configuration. If you want something you can set up in an afternoon and have working by dinner, this is not that. Maximum control in exchange for setup time is the trade it offers. We have a detailed comparison with Inventory Planner that covers pricing, features, and when each one makes sense.

Prediko

Cost: Priced on GMV, with a published price for every band: $49/mo under $100k, $119/mo at $100k to $500k, $199/mo at $500k to $2M, rising to $3,999/mo at $45M to $50M on monthly billing (Prediko pricing page, checked October 26, 2026).

Prediko pitches itself to Stocky migrators. It is Shopify-native, the interface is clean, and they lean hard into AI positioning with an assistant called Pia that answers inventory questions in natural language. If you want a modern-looking tool that feels like it was built in 2025 rather than 2015, Prediko checks that box.

The trade-offs: pricing is GMV-based, so your bill scales with revenue rather than features or SKU count. That matters for growing sellers: the same catalog costs more each time revenue crosses into a new band, even if nothing else changes. The forecasting leans on their AI model - you get recommendations but less visibility into what inputs and patterns are driving them. If you want to understand why the system is telling you to order 500 units, you are trusting the black box.

The bigger question is what happens on the Amazon side. As of October 2026 Prediko has a native Amazon integration that reads FBA inventory and Amazon sales into its forecast. It cannot create FBA shipments, so if you send stock to FBA you still decide the quantities and build every inbound plan yourself in Seller Central. It is built for Shopify-led sellers who want a polished, AI-forward experience. See how it compares to ReplenishRadar.

Monocle

Cost: $47/mo, $67/mo, and $89/mo, tiered by monthly order volume. Free trial. Rated 4.6 from 26 reviews on the Shopify App Store at the time of writing.

Monocle is Shopify-exclusive and forecasting-first. Its machine-learning model trains on your own store's history and gets better as it accumulates data, which means it is stronger in year two than in month one. Two features stand out on paper: it detects stock-out periods and excludes them from the forecast, so a month where you sold zero because you had zero does not teach the model that demand collapsed, and it surfaces products that tend to sell together.

Same caveat as Stockful: this is a description, not a review. And the same ceiling: Shopify only, no Amazon.

Pricing on order volume rather than SKU count is worth checking against your own numbers. A store with 300 SKUs and heavy repeat volume pays more here than in a SKU-priced tool, and a store with 5,000 slow-moving SKUs pays less.

Bigger systems than Stocky ever was

Cin7 (formerly Dear Systems)

Cost: $349/month and up.

Cin7 is an ERP-adjacent tool. If you do manufacturing, wholesale, and DTC, and you need accounting integrations, warehouse management, and B2B order processing alongside inventory planning, it might be the right move.

For most Stocky users, this is overkill. Stocky was a simple tool for simple needs. Jumping to an ERP because your simple tool got shut down is like replacing a Honda Civic with a semi truck because the Civic got recalled. Unless you were already outgrowing Stocky's scope, a focused inventory tool will serve you better and cost less. If you are seriously considering Cin7, read our detailed Cin7 alternative comparison first.

Katana

Cost: Free to 30 SKUs, then a custom annual quote.

Katana is built for manufacturers who sell DTC. If you make your own products on Shopify, Katana handles raw material planning, production scheduling, and finished goods inventory in one system. For makers and manufacturers, it fills a different niche than Stocky did.

If you do not manufacture, Katana is not the right fit.

Starshipit WMS and other warehouse systems

Cost: quote-based.

Starshipit is a shipping platform that has moved into warehouse management, and it turns up in most Stocky-alternative lists now. A WMS covers purchase orders, inbound receiving and multi-location stock, so on paper it does tick the Stocky boxes, and it adds pick and pack workflows, barcode scanning and multi-carrier shipping on top.

Be clear about the fit. If you are picking and packing your own orders out of your own warehouse and that process is the thing hurting you, a WMS is the right category and Stocky was never really solving that problem for you anyway. If your problem is deciding what to reorder and when, a WMS is a large, operationally heavy answer to a planning question. Stocky was a planning tool, so most of its users are in the second group.

Evaluate this one only if warehouse operations, not reorder planning, is what actually keeps you up.

When ReplenishRadar Is Not the Right Fit

We plan inventory for Shopify and Amazon sellers. Four situations point elsewhere.

• Under 30 SKUs and one supplier, a spreadsheet or the Shopify Admin is enough.
• Wholesale, EDI or accounting alongside inventory is the real need. Cin7 is built for that, and we do not do it.
• You make what you sell. Katana handles bills of materials and production orders.
• Pick, pack and barcode scanning in your own warehouse is the pain. A WMS such as Starshipit is built for that.

Migration Checklist

Stocky went dark on August 31, 2026, and Shopify said it would not provide exports afterwards, so what you have is whatever you exported before then. If you did, import it. If you did not, your sales history is still in Shopify and every tool below rebuilds forecasts from it; what you lost is purchase order history and supplier settings, which you re-enter once.

If you exported from Stocky before the shutdown, you have:

1. Your supplier list (names, lead times, contact info)
2. Any open purchase orders, for CSV import and reference while you cut over
3. Product cost data if you entered it in Stocky

If you did not, the supplier list is the one thing to rebuild by hand.

From Shopify (your new tool will pull this automatically):

• Product catalog and variants
• Current inventory levels by location
• Sales history (most tools pull 12-24 months)

What you will lose regardless:

• Stocky-specific reports and views
• Any custom configurations in Stocky's interface

The good news: your actual inventory data lives in Shopify, not in Stocky. Stocky was a layer on top. Now that it is gone, your products, stock levels, and order history are still in Shopify Admin. You are migrating the planning logic, not the data.

What We Would Do

With 100+ SKUs on Shopify and no Stocky, we would pick a tool this week rather than run without forecasting into Q4. Most tools on this list have a free trial and connect to Shopify by OAuth, so trialling two in parallel is an afternoon, not a project.

A migration goes best when the tools overlap. Run the new system in parallel. Verify the reorder suggestions make sense. Then switch.

A decision made in a rush tends to go one of two ways: overspending on a tool you do not need, or underspending on one that does not actually replace what you lost.

Try ReplenishRadar free for 14 days. Connect Shopify in five minutes, then once your data syncs see if the reorder suggestions match what you have been doing manually. Want to see what it does before signing up? Product overview.
