Shopify WMS Integration: Complete Guide 2026

A Shopify WMS integration automatically syncs your webshop with your Warehouse Management System. Orders from Shopify flow directly to your WMS for picking and shipping. Inventory updates in real-time on your webshop. Result: no manual data entry, fewer errors, and scalability from 10 to 1,000 orders per day. Duxly builds these integrations from €2,500.

What is a WMS and Why Do You Need It?

WMS Definition

A Warehouse Management System (WMS) is software that manages your warehouse operations: receiving inventory, storage, order picking, packing, and shipping. Popular WMS systems for e-commerce include Picqer (NL), ShipMonk (US/EU), Mintsoft (UK), and 3PL Central.

When do you need a WMS?

• 50+ orders per day: Manual picking becomes error-prone and slow
• Multiple sales channels: Shopify + bol.com + Amazon + physical store
• Multiple warehouse staff: Without WMS, nobody knows who is picking what
• Complex inventory: Variants, bundles, serial numbers, batch numbers
• External fulfillment: 3PL (third-party logistics) often requires WMS integration

How Does a Shopify WMS Integration Work?

1. Order flow: Shopify → WMS

• Customer orders on Shopify
• Shopify sends order via API to WMS
• WMS prepares order for picking
• Warehouse staff scans products with barcode scanner
• Order is packed and shipped
• Tracking code sent back to Shopify
• Customer receives shipping email with track & trace

2. Inventory flow: WMS → Shopify

• Inventory count in WMS (purchase, return, correction)
• WMS updates inventory via API to Shopify
• Shopify shows real-time inventory level
• When product is out of stock: automatically “Sold out” on product page
• No more overselling
