Stocky Alternatives in 2026: Every Option Compared (Including the Cheap One)

Short answer: If you run a large, multi-warehouse catalog and live in forecasts, pick Inventory Planner or inFlow. If you're a mid-market brand that wants AI forecasting plus POs, look at Prediko or Sumtracker. If you're a small retail store that just needs restock suggestions and purchase orders by vendor — the thing most people actually used Stocky for — you don't need $100–300/month of forecasting software. That's where a flat-rate tool like FillShelves ($15/mo) fits.

Shopify is sunsetting Stocky after August 31, 2026. It was pulled from the App Store on February 2, 2026, and the app plus all its APIs stop working after the deadline. You'll get read-only export access for at least 90 days after that, but the tool itself is done. (Shopify Help Center)

So the real question isn't "what's the best inventory app" — it's "what did I actually use Stocky for, and what's the smallest thing that replaces that?" This guide compares every serious option against that question.

The honest recommendations

If you have 2,000+ SKUs across multiple warehouses: Inventory Planner or inFlow

We're not going to pretend a $15 app replaces enterprise forecasting. If you're managing thousands of SKUs across multiple warehouses, syncing to Amazon and a 3PL, and your buyers plan purchasing on 90-day demand curves with lead-time variability — you need real forecasting, and you should pay for it.

Inventory Planner (starts ~$129/mo for 2 users) is the closest thing to a heavyweight Stocky successor: sales velocity forecasting, replenishment recommendations, multichannel connectors (Shopify, Amazon, QuickBooks), and open-to-buy planning. It's a legacy tool that has done this for years.

inFlow (starts ~$129/mo for 2 users) leans more toward warehouse operations and B2B — replenishment planning, cash-flow control, barcode workflows. If your bottleneck is the warehouse floor, not the forecast, inFlow is the stronger pick.

Recommending these honestly is the whole point. Most "Stocky alternative" lists exist to funnel you into the author's own expensive app. If forecasting is genuinely your problem, buy the forecasting tool.

If you're a growing DTC brand that wants AI forecasting + POs: Prediko or Sumtracker

Prediko (from ~$49–119/mo, scaling with SKUs and locations) is an all-in-one: AI demand forecasting, stock alerts, and purchase order management in one Shopify-native app. Good middle ground for brands that have outgrown "replace what sold" but aren't running a warehouse team.

Sumtracker (from ~$59/mo) is strongest when you sell the same inventory across multiple stores or channels and need real-time sync, plus practical forecasting on top. If multi-store sync is your pain, start here.

If you're a small retail store that just needs restock + POs: you don't need any of the above

Here's the part the other lists skip.

Most small brick-and-mortar Shopify (POS) merchants used Stocky for three things:

1. See what sold so they know what to reorder.
2. Generate a purchase order per vendor and send it.
3. Receive the stock and have Shopify inventory update.

That's it. No AI. No open-to-buy. No 90-day demand model. If that's you, paying $129/month for a forecasting engine you'll never open is lighting money on fire.

FillShelves does exactly those three things for $15/month flat — one plan, no tiers, no per-SKU or per-location pricing, 30-day free trial:

• Pick a sales window (30/60/90 days) → it shows units sold vs. on-hand and suggests "replace what sold."
• Suggestions become purchase orders grouped by vendor automatically — vendors are detected from your Shopify product data (more on why that matters below).
• Send each PO by email or PDF, then receive stock and it writes back to Shopify inventory.

It deliberately does not forecast. If you want trend lines and confidence intervals, buy Inventory Planner. If you want your shelves filled with what sold, this is smaller, cheaper, and faster.

The one migration detail that should influence your choice

When you leave Stocky, your supplier list does not come with you. Per Shopify's own Help Center, "Suppliers can't be exported from Stocky." There's no CSV, no API, no one-click export. Every vendor's contact info has to be rebuilt by hand in whatever tool you pick. (Shopify Help Center)

So when you evaluate alternatives, ask: how much work is rebuilding my vendors?

• Most tools: you re-type every supplier manually.
• FillShelves: it detects vendors automatically from the vendor field already on your Shopify products — so the one thing you can't export from Stocky is the thing you get back in one click. You add email + notes per vendor and you're done.

That single gap is worth more than any feature-checkbox comparison for a small store.

FAQ

Is Stocky really shutting down? Yes. Shopify is sunsetting Stocky after August 31, 2026. It was removed from the App Store on February 2, 2026, and the app and its APIs stop working after the deadline. You get read-only export access for at least 90 days afterward.

What is the best Stocky alternative in 2026? It depends on scale. Large multi-warehouse catalogs: Inventory Planner or inFlow. Growing DTC brands wanting AI forecasting: Prediko or Sumtracker. Small retail stores needing restock suggestions and purchase orders: FillShelves ($15/mo flat).

Is there a cheap Stocky alternative? Yes. FillShelves is $15/month flat with no tiers or per-SKU pricing, versus the $49–129+/month starting prices of the forecasting-heavy tools. See the full breakdown in Stocky Was Free. Its Replacements Cost $100–300/Month. Here's the Math.

Can I just use Shopify Admin instead of Stocky? Partly. Shopify Admin handles transfers, draft POs, and receiving, but it does not natively replace Stocky's restock suggestions or min/max replenishment — those require metafields or the Sidekick AI assistant. See Shopify Admin vs. Stocky: What You Actually Lose.

Can I move my Stocky suppliers to a new app? Not by export — supplier data can't be exported from Stocky. You'll rebuild vendors manually in most tools, or auto-detect them from your Shopify products with FillShelves.
