Best Shopify Inventory Tracking Apps in 2026
Shopify's built-in inventory works fine until you start receiving stock from suppliers regularly. Once your restocks come in by PDF or email, you'll want a dedicated Shopify inventory tracking app to keep stock levels and costs accurate without manual data entry. Here are the apps worth comparing in 2026.

What to look for in a Shopify inventory tracking app
1. Smart Restock — best for invoice-driven restocks
Smart Restock is purpose-built for stores whose stock arrives by supplier invoice. Drop a PDF, Excel file, or forwarded email and it extracts every line item, matches SKUs, calculates weighted-average cost, and posts the adjustment to the right Shopify location.
Best for: Stores that restock from suppliers and waste 30–60 minutes per shipment on manual entry.
Pricing: Starter from $9.99/mo (14-day free trial), Unlimited $49/mo.
2. Stocky (by Shopify) — discontinued
Shopify's own purchase-order tool, formerly free with Shopify POS Pro. Stocky shut down on August 31, 2026 and is now read-only for data export only, so it is no longer an option for new or existing stores. If you're coming off it, see our Stocky migration guide for what to export while you still can.
Replaced by: Shopify's native purchase orders and transfers for building POs in-app; an invoice-parsing tool if your suppliers send PDFs or emails.
3. Katana Manufacturing ERP
A full manufacturing ERP. Tracks raw materials, BOMs, and production. Overkill if you simply resell what suppliers ship you — most of its surface area is for makers.
Best for: Makers and small manufacturers, not pure resellers.
4. Cin7 / Dear Inventory
Enterprise-grade inventory and order management. Powerful but expensive and slow to set up. Most stores with under $5M in revenue won't see ROI from the implementation lift.
Best for: Larger multi-channel operations with dedicated ops staff.
How to pick
Start with how your stock arrives. If suppliers send PDFs or emails, an invoice-parsing tool like Smart Restock pays for itself in a week. If you build POs from scratch in-app, Shopify's native purchase orders and transfers now cover that at no extra cost — note that Stocky, which used to be the answer here, shut down on August 31, 2026 . If you manufacture or run multi-channel ops at scale, look at Katana or Cin7.
