Prioritise measurable metrics: transit times to major customer clusters, carrier network breadth, inventory visibility (WMS/API), thermal storage if needed, minimum order quantities, SLAs for pick-and-pack, and scalability for peak seasons. Also verify local labour availability and compliance with handling standards.

Transit times impact freight tiers and inventory buffer levels. Assess available line-haul frequency, parcel carrier pickup windows, and proximity to arterial routes—these determine shipping zones, costs, and the ability to meet B2B delivery windows without inflating inventory carrying costs.

Compare storage rates, handling charges (pick/pack), inbound receiving fees, kitting/assembly costs, minimum monthly charges, and accessorials like returns processing. Factor in carrier contract pass-throughs, seasonal surcharges, and technology integration fees to calculate true cost-to-serve.

Typical onboarding runs 6–12 weeks: contract & SOP finalization (1–2 weeks), WMS mapping and API integrations (2–6 weeks), test shipments and carrier onboarding (1–2 weeks), and pilot live operations. Include SKU master data, packing specifications, labeling rules, and performance KPIs in the checklist.
