Run your 3PL like a tech company
Willowcommerce 3PL WMS gives warehouse operators everything they need — multi-tenant client management, automated billing, inbound/outbound workflows, client portals, and AI-powered optimization. Scale from 5 clients to 500 without adding headcount.
Replace spreadsheet billing, manual client management, and disconnected tools with one purpose-built 3PL platform.
What Is 3PL Warehouse Management Software?
3PL warehouse management software is a specialized WMS designed for third-party logistics providers who store, manage, and fulfill inventory on behalf of multiple clients. Unlike generic warehouse software, 3PL WMS includes multi-tenant isolation, automated client billing, and self-service portals.
For 3PL operators, the biggest challenges are manual billing, client communication overhead, and scaling operations without proportionally scaling staff. Every new client means more spreadsheets, more emails, and more complexity.
Willowcommerce solves this with fully automated billing, dedicated client portals, native marketplace integrations per client, and per-client profitability tracking. It's natively connected to order management, inventory management, warehouse operations, and shipping — so every piece of the fulfillment workflow is unified.
Key Features
From receiving to shipping to invoicing — one system for your entire 3PL operation.
Multi-Tenant Client Management
Manage unlimited 3PL clients from one dashboard. Each client gets their own portal with scoped access to their inventory, orders, and billing — fully isolated data.
Automated Billing
Bill clients for storage (per pallet/bin/sqft), pick & pack fees, shipping markups, receiving charges, and custom services. Auto-generate invoices on configurable schedules.
Inbound Receiving
Create ASNs, scan barcodes on arrival, quality-check items, and put-away to locations. Clients can submit inbound requests through their portal.
Location Management
Zone → Aisle → Rack → Shelf → Bin hierarchy. Barcode-scannable locations with directed put-away and pick paths for maximum warehouse efficiency.
Outbound Fulfillment
Pick, pack, and ship orders with wave-based or order-based workflows. Batch label printing with carrier rate shopping across UPS, FedEx, USPS, and DHL.
Client Portal Access
Give each client a branded portal where they can manage store connections, view inventory, track orders, and see real-time billing — without accessing your internal tools.
Shipping Markup & Rate Cards
Set per-client shipping markups, custom rate cards, and carrier preferences. Clients see your rates while you profit on the spread.
Warehouse Analytics
Throughput metrics, labor efficiency, space utilization, and per-client profitability dashboards. Identify bottlenecks and optimize operations.
