Stocky Shuts Down Aug 31, 2026 — 5 Best Shopify Alternatives

⚠️ The purchase-order deadline is earlier than the shutdown. That window has arrived. Shopify tells merchants to stop creating new purchase orders in Stocky about two weeks before it closes on August 31, so raise nothing now that you cannot receive in time, and close out anything still in transit — a PO you cannot receive is stock you cannot account for. Shopify's own words: *"receive and close all open, in-transit purchase orders in Stocky before the deadline."* (Shopify's migration page)

Stocky is gone. Now what?#

If you're a Shopify seller who relied on Stocky for purchase orders and inventory management, you already know: Shopify removed Stocky from the App Store on February 2, 2026, and it fully shuts down on August 31, 2026. The features were partially absorbed into Shopify's admin, but only for POS Pro users — and even then, the functionality is a shadow of what Stocky offered.

And Stocky isn't the only casualty. TradeGecko, once the go-to inventory management tool for ecommerce sellers, was acquired by Intuit in 2020, rebranded as QuickBooks Commerce, and then shut down entirely in June 2023.

Two of the biggest names in Shopify inventory management — gone in two years.

So what are Shopify sellers using instead? Here are the five best alternatives in 2026, with honest pricing and feature comparisons.

What Shopify sellers actually need#

Before we compare tools, let's be clear about what Shopify's built-in inventory can't do:

• No purchase orders — you can't track what you ordered from suppliers
• No demand forecasting — Shopify shows what sold, not what will sell
• No reorder points — no automatic alerts when stock hits a threshold
• No cost/margin tracking — the cost field exists but Shopify doesn't use it
• No supplier management — just a "vendor" text field
• No barcode scanning for inventory — only through Shopify POS for checkout

If you're managing more than 100 SKUs, these gaps become painful. That's why Stocky existed in the first place.

1. InventoryQuick — Best overall for Shopify sellers#

Price: From $19/mo (Starter) to $149/mo (Business). 7-day free trial.

InventoryQuick is purpose-built for sellers who need real inventory management without enterprise complexity. It connects to your Shopify store and syncs products, variants, and stock levels in real-time (new store connections are paused) — meanwhile CSV import covers the same catalogue.

What makes it different:

• AI assistant — ask "what's running low?" or "create a PO for my top supplier"
• Shopify sync (new store connections are paused) — products import automatically with variants, prices, barcodes. Stock changes flow both directions
• Purchase orders — full PO workflow with supplier management and receiving
• Demand forecasting — ML-powered predictions based on your sales history
• Barcode scanning — scan from any phone camera, no special hardware
• Multi-location — track stock across warehouses, stores, and job sites

Best for: Shopify sellers with 100-5,000 SKUs who want Stocky-level features plus AI at a fraction of the price.

What it replaces: Stocky (everything it did, plus forecasting and AI), TradeGecko (at 1/7th the price)

2. Cin7 Core — For large multi-channel sellers#

Price: From $349/mo. No free tier.

Cin7 is a full-scale inventory and order management platform built for mid-market sellers doing high volume across multiple channels (Shopify, Amazon, eBay, wholesale).

Pros:

• Deep multi-channel support (Amazon, eBay, Shopify, WooCommerce, EDI)
• Warehouse management with pick/pack/ship
• B2B portal for wholesale customers

Cons:

• $349/mo minimum — overkill for most Shopify sellers
• Complex setup (weeks of onboarding, often requires paid implementation)
• Frequent complaints about buggy sync and slow support
• Annual contracts pushed aggressively

Best for: Sellers doing $1M+ in revenue across 3+ sales channels who need enterprise-grade warehouse management.

3. Katana — For manufacturers who sell on Shopify#

Price: From $299/mo (Core). Limited free plan (30 SKUs).

Katana is a manufacturing-focused inventory platform. If you make products (not just resell them), Katana handles bill of materials, production scheduling, and shop floor management alongside inventory.

Pros:

• Bill of materials and production planning
• Shop floor control with real-time tracking
• Good Shopify sync for manufactured products

Cons:

• $299/mo minimum — expensive for small sellers
• Manufacturing-focused — overkill if you're not a maker
• Limited features below the Professional tier
• Occasional sync delays reported

Best for: Shopify sellers who manufacture their own products and need production planning alongside inventory.

4. Trunk — For multi-channel sync only#

Price: From $35/mo. Free trial.

Trunk is laser-focused on one thing: keeping inventory in sync across multiple sales channels. If you sell on Shopify, Amazon, and Etsy, Trunk makes sure a sale on one channel updates stock on all others.

Pros:

• Simple, reliable multi-channel sync
• Affordable starting price
• Easy setup (15 minutes)

Cons:

• Sync only — no purchase orders, no forecasting, no supplier management
• Not a full inventory management system
• Limited reporting and analytics

Best for: Sellers who just need stock sync across channels and nothing else. If you need POs, forecasting, or warehouse management, look elsewhere.

5. inFlow — For desktop-first inventory management#

Price: From $129/mo (Entrepreneur). 14-day trial.

inFlow is a traditional inventory management system with a desktop app and cloud sync. It's been around since 2007 and has a loyal user base.

Pros:

• Full inventory management with POs, sales orders, and reporting
• Barcode scanning with label printing
• Multiple integrations (Shopify, WooCommerce, Amazon)

Cons:

• $129/mo minimum — mid-range pricing
• Desktop app feels dated compared to modern web apps
• Mobile app is limited
• Setup is more involved than cloud-native tools

Best for: Sellers who prefer a desktop-first workflow and need traditional inventory management features.

Comparison table#

The bottom line#

Stocky was good for its time, but it's gone. TradeGecko was better, but it's also gone. The Shopify inventory landscape in 2026 is split between expensive enterprise tools (Cin7, Katana) and lightweight sync-only tools (Trunk).

If you want what Stocky and TradeGecko offered — purchase orders, stock management, forecasting — without paying $200-350/mo, InventoryQuick is the closest replacement at a fraction of the cost — including GST-ready purchase orders (ex-tax costs, tax-inclusive totals that match your supplier invoice), partial receipts, and average cost tracking on every receive. And the AI assistant is something none of the legacy tools ever had.

Start your 7-day free trial — import your catalogue by CSV the same day and see your active products in one place, variant by variant (new store connections are paused).
