Prioritize order accuracy, on-time dispatch rate, inventory accuracy, average pick-pack cycle time, cut-off times for same-day shipment, returns turnaround, and SLA remedies. Also evaluate WMS/API integration, carrier connectivity, real-time reporting, and scalability to handle peak volumes without service degradation.

Location affects mileage-based transport costs, regional carrier service frequency, and access to cross-border corridors. Closer proximity to major routes reduces transit time and fuel expense, while strong carrier density lowers contract rates and improves routing options for both domestic and international lanes.

B2B needs prioritize pallet handling, dock scheduling, and bulk pick efficiency; DTC emphasizes fast pick-and-pack, configurable packaging, returns processing, and high SKU-level accuracy. Across both, a modern WMS, API/EDI connectivity, and yard management are essential for visibility and SLA compliance.

Negotiate transparent unitized pricing (picks, packs, storage tiers), flexible labor and storage clauses for peak seasons, clear SLA KPIs with service credits, minimum volume terms, and defined offboarding processes. Ensure access to reporting and audit rights to monitor true landed cost and identify scope-change charges.
