3PL Warehouse Management Systems: Features & Benefits

Quick Overview

A 3PL warehouse management system (WMS) is software designed to help third-party logistics providers manage inventory, warehouse operations, orders, and fulfillment for multiple clients from a single platform. Unlike a basic warehouse system, a 3PL WMS needs to support multi-client inventory, client-specific workflows, order management, reporting, and billing.

Key Facts about 3PL Warehouse Management Systems at a Glance:

• A 3PL WMS manages warehouse operations on behalf of multiple customers.
• Receiving, putaway, picking, packing, and shipping can be managed digitally.
• Many systems integrate with ecommerce platforms, ERPs, marketplaces, and transportation systems.
• Automated reporting helps clients monitor warehouse performance.
• 3PLs can use WMS data for more accurate storage and fulfillment billing.

What Is a 3PL Warehouse Management System?

A 3PL warehouse management system is specialized warehouse software used by third-party logistics companies to manage goods belonging to different customers.

A 3PL WMS must manage multiple businesses, each potentially having different products, inventory rules, customers, service levels, and fulfillment requirements.

How Does a 3PL WMS Work?

A typical workflow looks like this:

Inbound shipment → Receiving → Inventory check → Putaway → Storage → Customer order → Picking → Packing → Shipping → Inventory update

1. Receiving

When inventory arrives at the warehouse, the WMS records quantities, SKUs, purchase orders, cartons, pallets, and other relevant information.

Barcode scanning can reduce manual entry and help warehouse teams identify discrepancies during receiving.

2. Putaway and Storage

The system determines inventory storage locations based on warehouse rules, product characteristics, available space, or client requirements.

This helps warehouses use storage capacity more efficiently.

3. Inventory Management

A 3PL WMS provides visibility into inventory by client, SKU, location, batch, lot, or other attributes supported by the system.

Depending on the operation, inventory can be tracked by:

• Available quantity
• Reserved quantity
• Damaged or quarantined stock
• Inbound quantity
• Allocated inventory

4. Order Fulfillment

When an order enters the system, warehouse staff can receive digital instructions for picking, packing, and shipping.

The WMS can support different picking strategies, including:

• Single-order picking
• Batch picking
• Wave picking
• Zone picking

The right method depends on order volume, SKU mix, and warehouse layout.

Key Features of a 3PL Warehouse Management System

Why 3PLs Need Specialized WMS Software?

A 3PL WMS helps standardize processes while allowing different clients to have different operational requirements.

For example, one customer may require FIFO inventory rotation, another may require lot-level tracking, while another may need individual-unit fulfillment. A capable system can configure workflows according to each client's requirements.

3PL WMS Integrations

A warehouse management system becomes significantly more useful when it connects with the systems already used by the business.

Common integrations include:

Ecommerce platforms → ERP systems → Marketplaces → Order management systems → Transportation systems → 3PL WMS

How to Choose a 3PL Warehouse Management System

Businesses evaluating a 3PL should look beyond whether the provider simply has a WMS.

Consider:

• Inventory visibility: Can you access accurate, near-real-time inventory data?
• Integration: Can the WMS connect with your ecommerce, ERP, or marketplace systems?
• Multi-client capabilities: Can the system handle different inventory and workflow requirements?
• Scalability: Can it support increasing SKUs and order volumes?
• Reporting: Can you access the operational information you actually need?
• Traceability: Can inventory movements be tracked from receiving through shipment?
