Assess WMS functionality and API/EDI connectivity, pick-and-pack throughput and accuracy rates, available value-added services (kitting, returns, labeling), SLA definitions for order cycle times, and local labor flexibility. Also validate bonded or temperature-controlled capacities if your SKU profile requires special handling.

Proximity to major highways and regional carrier hubs reduces line-haul distances and enables more predictable transit times. That lowers FTL/LTL spend and supports same-region delivery windows. Evaluate 3PLs on their carrier contracts, consolidation capabilities, and routing efficiency to control per-shipment costs.

Yes. Many operators offer scalable, shared-space models with flexible storage tiers and temporary labor pools for peak seasons. Prioritize providers with modular pricing, transparent onboarding fees, and WMS features that support rapid SKU onboarding and variable pick profiles to avoid disruption during surges.

Consider inventory placement to reduce lead time versus carrying cost, cross-dock versus storage trade-offs, customs and bonded processing needs for imports/exports, multimodal links to nearby ports, and SLA alignment for order fill and replenishment frequency. Model total landed cost and service risk before committing capacity.
