Prioritize WMS capabilities (real-time inventory, batch/lot control), API integrations with your OMS and carriers, SLA guarantees for pick/pack/ship, returns handling, and reporting. Also assess onboarding timelines, EDI/API documentation, and whether they support cross-docking or value‑added services relevant to your SKU mix.

Look for dock density, cubic clear height, racked vs bulk capacity, temperature zones, bonded storage, and onsite customs clearance. Evaluate labor pool stability, night shifts, and proximity to major road and rail nodes to minimize last‑mile and interregional transit costs.

Transit windows affect inventory days and safety stock—longer lanes increase carrying cost. Strong carrier competition from Krustpils reduces freight rates and enables parcel zone optimization. Analyze lane lead times, carrier cutoffs, and multi-carrier routing to balance cost vs service for your top markets.

Request transparent line‑item pricing for receiving, storage (by pallet/cubic), pick & pack by piece or order, returns, and special handling. Seek volume tiers, minimums, pass‑throughs for fuel/insurance, and clear SLA penalties. Include scalability clauses for seasonality and defined review periods for re‑pricing.
