Disclosure: I built SimpleStock, one of the apps mentioned below. I’ll tell you when it fits and when it doesn’t. If something else is better for your store, I’ll point you there.

If you’ve used Stocky for inventory and you’re not paying for Shopify POS Pro, you have a problem on a deadline. Stocky is shutting down completely on August 31, 2026, and if you don’t act soon, you’ll lose reorder alerts, supplier lists, and purchase order workflows on a single day. This is a quick rundown of what’s happening, who needs to switch, and the main Stocky alternatives worth looking at — including the one I built.

TL;DR

What	When	Status
Demand forecasting + stock transfer removed	July 7, 2025	✅ Already gone
App Store listing removed	February 2, 2026	✅ Already gone (no new installs)
Full shutdown	August 31, 2026	⚠️ ~16 weeks away as of May 2026

If you’re on POS Pro ($89/location/mo), Shopify is moving you to native inventory tools in Admin and POS. Note: native does not include the demand forecasting Stocky used to have. If you’re not on POS Pro, you need a third-party Stocky replacement before the deadline. Best picks below.

What’s Happening to Stocky

Stocky has been Shopify’s free-with-POS-Pro inventory companion for years: purchase orders, reorder points, supplier management, demand forecasting. Useful for stores that don’t need full enterprise inventory software but need more than the bare-minimum Shopify Admin.

That arrangement is winding down in three steps:

July 7, 2025: Stock transfers and demand forecasting were the first to go. If you remember when forecasting suddenly stopped working, that’s why.

February 2, 2026: Stocky was quietly removed from the Shopify App Store. Existing installs kept running. New ones became impossible. You can verify this yourself — searching “stocky” in the App Store now turns up alternatives, not the original.

August 31, 2026: Hard shutdown. APIs go offline. Purchase orders stop syncing. Supplier lists become read-only for a brief window, then disappear.

Today is May 8, 2026. That’s roughly 16 weeks of runway.

Stocky Without POS Pro: What You Need to Do

Most posts about this skip past the actual decision tree, so let me be direct.

If you’re on POS Pro ($89/location/month, paid annually $79): Shopify is moving you to native inventory features in Shopify Admin and POS. You probably don’t need a third-party app. The catch is that native tools don’t replicate Stocky’s demand forecasting — that’s gone for everyone. If forecasting was the reason you used Stocky, native won’t replace it, and a third-party app is still worth considering.

If you’re not on POS Pro: this is you, and most of this article is for you. You have two options. Either start paying $89/location/month for POS Pro (which gets you Shopify’s native tools but not forecasting), or pick a third-party Stocky replacement that costs less than POS Pro but does what you actually need.

If you’re a small or mid-sized store and POS Pro feels like a stretch, one option to know upfront is SimpleStock — flat $14.99/month with multi-location included, no POS Pro needed. Free plan covers 30 SKUs with no credit card. I’ll cover the others below too.

The 4-Step Migration Playbook

Step 1: Export your Stocky data while it still runs

Don’t wait. Export now, in May or June. Things you want a copy of:

• Supplier list (names, contact info, lead times you’ve fine-tuned)
• Purchase order history (recent ones for reference, older for records)
• Reorder points and min/max levels per SKU
• Cost prices if you track margins through Stocky

Also export your full Shopify product CSV from Admin. Most replacement apps can import it directly, but having a local backup is cheap insurance.

The boring part: Stocky’s CSV export is okay but not great. Set aside an hour. If you have under 200 SKUs you’ll be fine. If you’re larger, plan a half-day for cross-referencing.

Step 2: Pick a replacement

This is the call you’re trying to make. The honest comparison is below. Quick version: pick based on how much forecasting you actually need, your SKU count, and what you’re willing to pay.

If you migrated from Stocky because you wanted simple-but-not-bare-bones inventory and you don’t have POS Pro, SimpleStock has a free 30-SKU plan and a 14-day Growth trial — under 10 minutes to try.

Step 3: Migrate your supplier and reorder data

Here’s what most apps automate (because they pull from Shopify directly):

• Product catalog
• Variant SKUs
• Inventory quantities at locations
• Sales history (rebuilt from order data)

Here’s what you’ll re-enter manually (because it lived inside Stocky):

• Supplier names, emails, lead times
• Reorder thresholds per SKU (or per vendor)
• Safety stock buffers
• Cost prices, if those weren’t in Shopify

Budget about 30-60 minutes for 100 SKUs. CSV import helps if your replacement app supports it. Most do.

Step 4: Run both systems in parallel for two weeks

Don’t cut over the day Stocky dies. Run your new app alongside Stocky from now through August. Test purchase orders. Verify stock adjustments sync. Watch reorder alerts fire at the right thresholds.

This is the step nobody mentions in migration guides because it’s tedious. It’s also the step that prevents a stockout in September.

Best Stocky Alternatives in 2026 (Honest Comparison)

I looked at the apps actively replacing Stocky. Here’s what I’d say if a friend asked.

Prediko — for stores that lived on Stocky’s forecasting

Pricing: $49 to $349 per month, tiered by GMV.

If demand forecasting was the main reason you used Stocky, Prediko is the closest functional replacement. Their AI replenishment suggestions are genuinely useful, and the UI is clean. Lower tier ($49) handles most small-to-mid stores. Upper tier ($349) starts making sense around $2M GMV.

Where it gets harder: if you’re a small store running straightforward wholesale reorders, you’re paying for AI you won’t use. Forecasting is real value, but only for stores with enough sales velocity to forecast against.

Assisty — middle ground for AI-assisted stores

Pricing: from $19/month, with higher tiers for larger stores. Check their pricing page for current numbers; the upper tiers move around.

Assisty’s $19 entry tier is genuinely usable for smaller stores. They’ve built decent Shopify Plus integrations on the upper plans. If you’re going to scale and want forecasting baked in early, it’s worth a trial.

The tier choice can feel confusing. Spend 15 minutes auditing your actual usage before committing to a plan.

Sumtracker — multi-store sync first

Pricing: from $49 per month.

Sumtracker’s strength is syncing inventory across multiple Shopify storefronts and external channels. If you sell on more than one Shopify store, or you need to reconcile inventory between Shopify and another system, this solves a problem most apps don’t.

If you’re a single-store Shopify merchant, you’re paying for sync infrastructure you won’t touch.

Inventory Planner — enterprise-grade

Pricing: starts at $299/month, custom pricing above that for enterprise.

This is real enterprise software. Forecasting, replenishment planning, multi-warehouse, deep analytics. If you have a team running inventory at scale, $299 is fine.

If you’re a small or mid-sized merchant migrating from a free Stocky install, this is way too much app. Don’t even consider it unless you have someone full-time on inventory.

SimpleStock — for small stores that just want Stocky to keep working

Pricing: free for 30 SKUs, $14.99/month for Growth (multi-location, CSV export, vendor lead times, reorder alerts), $29.99 for Pro (unlimited SKUs).

This is the one I built. The pitch is: if Stocky was good enough for you and you don’t want to pay $89/location/month for POS Pro to keep using Shopify native tools, SimpleStock does the same job for $14.99 flat. Multi-location is in the Growth plan, not paywalled separately.

I’ll be straight about what it doesn’t do:

• No AI demand forecasting. Reorder calculations use the last 30 days of sales velocity, plus your vendor lead time and safety stock buffer. That’s enough for most small stores. It’s not enough if you’re trying to forecast holiday spikes a quarter out.
• Not built for 1,000+ SKU operations with deep analytics. It works, but Inventory Planner does that better.
• Shopify-only. No multi-channel sync. Use Sumtracker if that’s your problem.

If you’ve got under 500 SKUs, want simple, and don’t have POS Pro, this is the lane it’s in.

What I’d Actually Do If I Were You

Decision tree, no fluff:

• Lived on Stocky’s forecasting? → Prediko. The $49 tier is fine for most stores.
• Selling on multiple Shopify stores? → Sumtracker.
• Running inventory at $2M+ GMV with a team? → Inventory Planner.
• Want AI forecasting on a smaller budget? → Assisty. Try the $19 tier first.
• Just want Stocky-without-POS-Pro? → SimpleStock. Free plan, no card, ten minutes.

The only wrong answer is waiting until late August. Pick something this month, set it up alongside Stocky, and give yourself July to validate.

See If SimpleStock Fits Your Store

If you’re on Stocky and not sure what’s next, SimpleStock has a free plan: up to 30 SKUs, no credit card, no commitment. The paid Growth plan is $14.99/month with multi-location included. If 30 SKUs isn’t enough but the rest fits, the 14-day Growth trial is the fastest way to know.

Side note for the curious: I built SimpleStock as a solo project with Claude Code over a couple of weeks of evenings. It’s deliberately small. Not enterprise inventory software, just a clean replacement for what Stocky did well.
