Prioritize WMS integration and reporting, SLA-backed lead times, handling capabilities for your SKU mix (e.g., temperature control), scalable labor and slotting strategies, and transparent fee structures. Confirm carrier pickup windows and zone-skipping options to reduce parcel costs and transit days.

Location reduces driving distance to key consumption centers and improves access to primary trucking lanes, which lowers transit times and variability. Evaluate nearby intermodal points and common carriers serving the area to ensure consistent capacity during peaks.

Negotiate clear terms for storage (per pallet or cubic), handling (receiving, picking, packing), special services (kitting, returns), labor uplift during peaks, and minimum monthly charges. Request historical billing samples to validate estimated monthly spend and seasonality impacts.

Look for 3PLs with flexible workforce models, scalable racking and slotting, WMS-driven wave planning, and pre-negotiated carrier capacity. Service-level tiers and forecast-based labor planning help contain unit costs during surges while maintaining on-time rates.
