Most Shopify stores searching for warehouse management software end up looking at tools that cost $200-400 per month and are built for operations ten times their size. This guide explains the real difference between a WMS and inventory management, who actually needs each one, and what growing Shopify stores should use instead.
These two terms get used interchangeably but they solve different problems. Getting this distinction wrong leads to either buying expensive software you do not need or being frustrated that a basic inventory tool cannot do what you want.
A WMS tells warehouse staff exactly where to go, what to pick, and in what order. It manages the physical movement of goods — bin locations, guided picking routes, receiving workflows, barcode scanning for every movement. The goal is operational efficiency at high order volume.
An inventory tool tracks your stock levels, predicts demand, calculates when to reorder, and surfaces problems — dead stock, stockout risks, products losing margin. The goal is making better buying and selling decisions.
The vast majority of Shopify stores with 50-500 SKUs are in the second category. A WMS is genuinely overkill — the complexity and cost is built for operations that are picking hundreds of orders per day from a large physical warehouse. Adding that complexity to a store doing 20-50 orders per day creates more problems than it solves.
This includes stores selling both wholesale and direct-to-consumer from one location. That feels like a multi-warehouse problem, but it usually is not — see our guide on managing wholesale orders on Shopify without multiple warehouses.
Shopify has solid built-in tools for basic stock management. Understanding what is included helps you identify exactly where the gaps are before choosing a third-party solution.
Since Shopify discontinued Stocky in August 2026, there is no native purchase order tool. Stores that used Stocky for PO management and receiving now need a third-party replacement. For a full breakdown of alternatives, see our Stocky shutdown guide.

If your operation genuinely needs a full WMS, here are the tools that actually integrate with Shopify:

The gap in the market is not warehouse management software. It is inventory intelligence — the layer between Shopify's basic stock tracking and full enterprise WMS tools. Knowing what to reorder, when, and which products are costing you money.
Auto-calculated from your actual sales velocity and supplier lead time — not a round number you guessed.
Ranks every product by revenue contribution so you know where to focus your safety stock and tightest reorder points.
Flags products with 60+ days of no sales — the cash tied up in slow inventory you might not even notice.
Create, send, and receive POs with auto stock update — the Stocky replacement most stores actually need.
Shopify has basic inventory management built in — stock tracking per location, transfers between locations, and manual adjustments. It does not have a full warehouse management system. Features like barcode-guided picking routes, bin locations, receiving workflows, and purchase order management require third-party apps. Since Shopify discontinued Stocky in 2026, there is no native PO tool.
Inventory management tracks what you have, when to reorder, and which products are at risk. Warehouse management controls how physical operations happen inside a warehouse — picking routes, bin locations, receiving workflows, and barcode scanning for every movement. Small to mid-sized Shopify stores typically need better inventory management. Large fulfilment operations with multiple warehouse staff need a WMS.
For large operations needing true warehouse management, Fishbowl, Linnworks, and Extensiv (formerly Skubana) integrate with Shopify. These start at $200-400/month and are built for multi-warehouse operations with complex fulfilment needs. For most growing Shopify stores (50-500 SKUs), a WMS is overkill — what you need is an inventory intelligence tool that adds reorder points, demand forecasting, and dead stock detection.
Probably not, unless you are fulfilling 500+ orders per day from a physical warehouse with multiple staff picking simultaneously. The businesses that genuinely need a WMS have complex physical operations — guided picking routes, bin management, multi-warehouse routing with separate teams. Most Shopify sellers need better inventory intelligence: knowing when to reorder, which products are at risk, and which are tying up cash.
For basic warehouse inventory, use Shopify Admin → Settings → Locations to set up each warehouse, assign stock per location, and manage transfers. For incoming shipments, use the transfer feature or a third-party PO management app. For ongoing stock accuracy, do regular cycle counts comparing physical inventory to Shopify records. For intelligence on what to reorder and when, add an inventory app that calculates reorder points from your actual sales velocity.
Shopify discontinued Stocky on August 31, 2026. Stocky handled purchase orders, receiving, and basic reorder management. Since the shutdown, there is no native Shopify tool for PO management. Stores that used Stocky for warehouse receiving and PO tracking need a third-party replacement before the deadline.
