Prioritize network reach (carrier contracts and lanes), WMS and EDI capabilities, dock and racking capacity, SLA-backed KPIs (OTD, inventory accuracy, pick accuracy), scalable labor and contingency planning. Confirm value-added services for returns, kitting, and labeling to match your channel mix.

Model transit times using zone distribution analysis and historical carrier performance; compare parcel and LTL access, density-based zone skipping, and average last-mile mileage. Include landed cost modeling that accounts for regional freight rates, fuel surcharges, and dwell time to quantify savings.

Look for ISO-compliant racking, sufficient dock doors, temperature control if needed, robust WMS with ASN and batch control, barcode scanning, secure inventory segregation, and demonstrated experience with kitting, assembly, and returns handling to support B2B SLAs.

Expect a mix of storage (per pallet or per cubic meter), throughput fees (receiving, putaway, picks, pack), pick-and-pack labor, packaging materials, and ancillary charges (returns, kitting, special handling). Watch minimums, detention, and inbound receiving windows as primary cost drivers.
