Inventory for Shopify

Top 10 Shopify Inventory Management Apps (2026)

Shopify’s native inventory works for single-warehouse, simple-SKU brands. Above that, you need an inventory management system (IMS) — for multi-warehouse, purchasing, manufacturing, kitting, lot / batch, or barcode receiving. The right pick depends on SKU count, warehouse footprint, whether manufacturing is in scope, and your accounting platform.

How to choose

The 3 decisions that determine fit.

If you’re under $1M and single-warehouse

Stocky (free with Shopify POS Pro or Shopify Plus) or inFlow. You don’t need a real inventory platform yet — Shopify-native plus Stocky for PO management usually covers it. Wait until SKU count or warehouse count makes Shopify alone painful.

If you’re $1M–$10M on Xero or QuickBooks

Cin7 Core is the default — it pairs natively with both accounting systems and adds real inventory (multi-warehouse, manufacturing, purchasing) without forcing an ERP migration. Katana if manufacturing is the dominant complexity.

If you’re $10M+ with multi-channel and B2B

Cin7 Omni or Brightpearl if you want a one-platform OMS + inventory + accounting; NetSuite Inventory if you’re already on NetSuite or moving there; Fishbowl if you’re committed to QuickBooks Enterprise. Linnworks for UK-heavy multi-region operations.

Common questions

Questions operators ask before they choose

Does Shopify need a separate inventory app?
Below $1M and single-warehouse, no — Shopify’s native inventory plus Stocky (free with Plus or POS Pro) usually covers it. Above that, or with multi-warehouse, manufacturing, kitting, or lot tracking, a dedicated inventory app is the default.
How much do inventory apps cost in 2026?
Stocky: free (with Shopify POS Pro / Plus). inFlow: $89–$549/mo. Cin7 Core: $349–$849/mo. Cin7 Omni: $599–$2K+/mo. Katana: $179–$1,279/mo. Inventory Planner: $200–$2K+/mo by SKU count. Brightpearl: $35K–$110K/year. NetSuite Inventory: included with NetSuite (~$25K+/year).
Cin7 Core or Cin7 Omni — which is right?
Cin7 Core for $500K–$10M brands on Xero / QuickBooks needing inventory depth without ERP scope. Cin7 Omni for $2M–$30M brands needing multi-channel inventory + OMS + B2B + EDI as a quasi-ERP. They’re different products despite the shared brand.
Should manufacturing be in the inventory app or a separate MRP?
For light assembly and kitting, the inventory app (Cin7 Core, Cin7 Omni, Brightpearl, NetSuite) handles it well. For real manufacturing — discrete work orders, routings, production scheduling — Katana or a dedicated MRP usually wins.
When do we need a WMS instead of an IMS?
When the warehouse operation itself becomes the bottleneck — bin-level picking optimization, batch / wave picking, mobile barcode scanning across pickers, and slotting. Usually that means 10K+ orders/month from a single warehouse. WMS is operational; IMS is administrative.
