Key KPIs to require: on-time order fulfillment, order accuracy, inventory accuracy, and average order-to-ship time. Also verify returns processing time, inventory reconciliation cadence, and penalties or credits tied to SLA misses to align incentives.

• Prioritize warehouses with direct port access or bonded facilities to reduce import dwell and clearance time.
• Evaluate proximity to major road corridors and regional carriers for faster distribution across the island and neighboring markets.

Require a modern WMS with open APIs or EDI for real-time inventory visibility, order management system integration for channel orchestration, and reporting tools for cost-to-serve analysis. Confirm marketplace connectors, automated ASN/PO handling, and returns management.

Pricing differs by order density and handling complexity. Expect higher per-order pick-pack fees and minimums for low-volume ecommerce, while B2B volumes often negotiate tiered storage, pallet-handling, and outbound rate breaks. Also account for cartonization, kitting, dimensional weight, and fuel or peak-season surcharges.
