Focus on WMS compatibility and data exchange, inventory accuracy and reconciliation processes, SLA definitions for order cycle time, pick-and-pack throughput, returns handling, and multi-temperature capabilities. Also verify carrier coverage to your customer base, cross-dock options, bonded/customs support, and the partner's ability to scale during peaks.

Close proximity to ports and major corridors reduces drayage and inland transport charges, shortens lead times, and improves reliability for inbound freight. That lowers total landed cost and enables faster replenishment cycles. Evaluate average transit times to primary customer ZIPs and carrier frequency from local gateways.

Include fixed and variable storage (per pallet/CBM), inbound handling and putaway, pick-and-pack labor per order line, packaging materials, pallet wrap and shrink, outbound freight rates, cross-dock fees, returns processing, and any value-added services like kitting or labeling. Account for minimums and seasonal rate adjustments.

Request site tours and SLA documentation, review operational KPIs (OTIF, inventory accuracy, order cycle time), ask for customer references in similar verticals, run a short pilot or integration test with your WMS/ERP, and confirm escalation procedures and reporting cadence to ensure alignment before signing.
