Evaluate WMS integration and API capabilities, SLA definitions (order cutoffs, same-day/next-day windows), inventory visibility, scalable pick-pack capacity, and experience with B2B pallet workflows. Also review location proximity to highways/border crossings and available value‑added services like kitting, labelling and returns processing.

Closer proximity reduces line-haul distance and potential handoffs, lowering transport cost and lead time. Benefits include faster cross-border clearance, easier consolidation and improved carrier scheduling. Consider:

Negotiate clear unit rates, minimums, volume tiers, and surge pricing. Define KPIs (OTD, accuracy), billing cadence, chargeback rules, onboarding fees and termination clauses. Include provisions for seasonal capacity, inventory ownership, liability limits and audit access to WMS logs for transparency.

Yes—many regional 3PLs offer temperature-controlled chambers, bonded warehousing and reverse-logistics services. Validate certifications, temperature mapping, segregation protocols, customs authorizations and documented returns workflows to ensure they meet retailer and regulatory requirements.
