Focus on WMS integration, inventory accuracy rates, pick/pack throughput, dock‑to‑door lead times, and SLA penalties. Confirm available value‑add services (kitting, returns), cold‑chain capacity if needed, handling equipment, labor scalability, and proven customs clearance processes for inter‑island and cross‑border flows.

Port proximity and feeder service frequency directly affect transit windows and consolidation opportunities. Limited direct sailings can increase handling and dwell time; using regional consolidation, multi‑modal routing, and zone‑skipping carriers can lower landed cost and improve delivery predictability.

Negotiate transparent throughput pricing (per‑pick, per‑pallet), minimum monthly charges, peak season clauses, inbound consolidation fees, and fuel or service surcharges. Include SLA‑linked rebates, scalable labor rate terms, inventory shrinkage liability, and reasonable termination/notice periods to manage long‑term cost exposure.
