Assess the 3PL’s domestic and international carrier contracts, transit time reliability to key destinations, frequency of linehaul departures, and intermodal connections to Riga ports and rail. Verify SLA performance data, typical lead times for pick‑pack, and backup carrier options to maintain service during peak demand or disruptions.

Prioritize clear staging and cross‑dock capacity, racked storage density, temperature‑controlled zones if needed, automation for pick accuracy, and IT integration (WMS/API). Evaluate dock count, yard depth for trailers, security, and proximity to major road links to minimize turnaround time.

Include base storage rates, handling and pick/pack fees, inbound/outbound freight estimates, minimum volume commitments, seasonal rate adjustments, and chargeback policies. Model total landed cost including last‑mile surcharges, returns processing, and inventory carrying costs to compare providers accurately.

Require documented capacity flex plans, short lead times for expanding footprint or labor, seasonal staffing strategies, and contingency routing. Confirm the provider’s technology for demand forecasting and capacity planning, plus SLA penalties and escalation procedures to protect service levels during spikes.
