Prioritize inventory accuracy, SKU-level traceability, pick-and-pack throughput, and returns handling. Verify WMS/API integrations for OMS/carrier connectivity, dock and staging capacity for peak cycles, and documented KPIs (OTD, accuracy, lead times) to ensure visibility and scalable service.

Evaluate trunking lanes to primary ports and intercity hubs, frequency of carrier departures, and road quality for reliable transit times. Consolidated LTL and pallet carrier options, plus routable lanes to key customers, materially reduce per-shipment cost and dwell time.

Require pallet racking, configurable pick modules, temperature control where needed, sufficient dock doors, secure perimeter, and redundant utilities. Confirm WMS capabilities, barcode scanning, and real-time inventory reporting to minimize errors as volumes scale.

Compare fixed vs variable charge mixes, minimums, and activity-based fees. Negotiate SLAs for accuracy, lead time, and claims with financial remedies. Model total landed cost including inbound, storage, pick/pack, returns, and last-mile to reveal true cost trade-offs.

Confirm customs clearance points, documentation requirements, and any regional trade agreements affecting duties. Assess bonded warehouse options, local licensing, and compliance services offered by 3PLs to prevent clearance delays and additional duties for cross-border flows.
