If you're working with a third-party logistics (3PL) provider or using a Warehouse Management System (WMS), Sumtracker can integrate seamlessly to give you centralized inventory control, while your fulfillment partners handle day-to-day operations.
🤝 What Is a 3PL Partner?
A 3PL (Third-Party Logistics) partner takes care of storing and shipping your products. They typically:
Hold all or part of your inventory
Pick, pack, and ship customer orders
Communicate with your online store
Update inventory levels and shipping statuses on your sales channels
🏭 What Is a WMS?
A Warehouse Management System (WMS) is software used to manage warehouse operations. It includes:
Bin/location-level inventory management
Efficient picking, packing, and stock movements
Stock counting and replenishment processes
Accurate inventory tracking inside your warehouse
🔄 How Does Sumtracker Work With a 3PL or WMS?
You can integrate Sumtracker with your 3PL partner’s software or WMS to create a connected, streamlined workflow.
✅ Integration Capabilities
We can sync the following between systems:
Purchase Orders (POs) – Plan and send incoming stock info to the warehouse
Receipt of Goods – Confirm and record what was actually received
Stock Transfers – Track inventory movement between storage locations or warehouses
Inventory Adjustments – Keep stock levels accurate across all platforms
🧭 Choose Your Inventory Source of Truth
You can decide where inventory data originates:
Sumtracker as the master – Centralized planning, forecasting, and stock control
3PL or WMS as the master – Let the fulfillment system lead inventory updates
We'll help configure this based on your workflow.
