What are the best warehouse management systems for multi-client 3PL operations with real-time inventory visibility?

For multi-client 3PL operations, the “best” WMS usually means one that can handle:

• Multiple clients / tenants with separate rules, billing, and reporting
• Real-time inventory visibility across locations and customers
• Advanced order routing and wave management
• Lot, serial, and expiry tracking
• Client portals / EDI / API integrations
• Strong labor, billing, and slotting support
