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)
Shopify's own purchase-order tool, free with Shopify POS Pro. Good if you already use Shopify POS in physical locations. Less useful for stores whose suppliers send free-form invoices, since Stocky expects you to build purchase orders manually inside the app.
Best for: Retail stores already on POS Pro who build POs from scratch.
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, Stocky is free with POS Pro. If you manufacture or run multi-channel ops at scale, look at Katana or Cin7.
