Prioritize location proximity to major roads and ports, real-time WMS integration, scalable racked capacity, SKU velocity segmentation, and SLAs for pick/pack/ship. If helpful, look for:

• Carrier access and zone-skipping options
• Returns and value‑add service capabilities

Carrier density and direct lanes reduce transit time and zonal charges. Choosing a 3PL in proximity to primary carriers enables better negotiated rates, consolidated LTL moves, and faster parcel delivery windows—key to lowering cost per order and meeting two‑day delivery targets.

Model fixed and variable cost elements: storage cubic pricing, inbound receiving fees, pick/pack labor rates, outbound packaging, minimum monthly volumes, and transportation surcharges. Include costs for WMS integration, cross-dock handling, and returns processing to get a complete landed‑fulfillment view.

Look for a modern WMS with API or EDI connectivity, real-time inventory synchronization, ASNs for inbound management, configurable picking logic, and reporting dashboards. These capabilities enable accurate inventory visibility, reduce stockouts, and streamline order routing between eCommerce and B2B channels.
