Key factors include order cycle times, pick-and-pack throughput (orders/hour), inventory accuracy targets, WMS integration and reporting, bonded storage capability, reverse logistics processes, and carrier connectivity to primary markets. Also assess seasonal capacity, SLA penalties, and real-world unit handling costs per SKU.

Proximity to ports, railheads and reliable road links directly reduces handling steps and carriage distance, lowering landed costs and variability in lead times. Evaluate modal mix, container unpacking options, carrier frequency, and seasonal road reliability to size buffer inventory and optimize routing agreements.

Negotiate clear KPIs: OTIF, order accuracy, inventory accuracy, average dwell time, and shrinkage thresholds. Define billing transparency (per-pallet, per-pick), minimums, capacity scalars for peak seasons, liability limits, and termination clauses tied to sustained SLA breaches to protect service continuity and cost predictability.
