Assess WMS and API/EDI integration, carrier partnerships and parcel density, lead times for inbound receipts, pick/pack and throughput capacity, slotting and storage density, SLA and chargeback terms, and value‑added services (kitting, returns). Also review workforce flexibility for peaks and the 3PL’s reporting and exception management capabilities.

Common drivers: pallet or cubic storage, per‑pick fees, inbound receiving charges, putaway, returns processing, packing materials, and labor surcharges. To optimize costs, consolidate SKUs by velocity, negotiate volume discounts, use blended storage tiers, and align service levels to channel margin rather than one‑size‑fits‑all pricing.

Proximity to dense urban demand shortens last‑mile routes and supports multiple day‑certain delivery options. Consolidation in Sutton can enable carrier densification, reduce multi‑stop inefficiencies, and improve on‑time delivery percentages for both next‑day and same‑day services when combined with optimized cutoffs and carrier selection.
