Prioritize measurable KPIs and system capabilities: order-to-ship lead time, pick accuracy, on-time dispatch rate, and average handling cost per order. Verify WMS/OMS APIs, carrier integrations, dimensional weight handling, returns processing, and access to multiple parcel partners to enable zone-skipping and negotiated rates.

Key infrastructure: dock-high loading bays, cross-dock capacity, trailer marshalling yard, hardstand for container operations, and temperature-controlled zones. Carrier access should include local courier networks, national FTL/LTL carriers, and forwarders for maritime lanes to ensure flexible routing and reliable lead times.

Optimize by balancing inventory days against transport frequency: use near-port consolidation for inbound LTL, regional stock for express delivery, and seasonal satellite space. Negotiate bundled services (receiving, pick-pack, and parcel postage) and leverage local labor and lower facility rents to reduce overall cost-to-serve.

Require WMS with real-time inventory APIs, OMS connectivity, barcode or RFID support, and automated reporting. Also validate carrier label automation, returns management workflows, SLA monitoring, and support for EDI or API-based order exchanges to enable rapid scale and channel visibility.
