Prioritize warehouse footprint and racking density, WMS/API connectivity, inbound/outbound capacity, SLA and KPI guarantees (inventory accuracy, order lead time, pick rates), returns handling and available value‑added services such as kitting, labelling and cold chain where required.

Map primary and alternate lanes, request lane-specific transit studies and sample ETAs, verify multimodal options (road, inland container depots), confirm bonded/clearance capabilities, and audit current carrier contracts and last‑mile partners to validate published transit assumptions.

Expect line items for storage (per pallet/CBM), receiving and putaway, pick-and-pack (per pick or per order), handling for returns, kitting fees, minimum monthly charges, and accessorials. Negotiate SLA targets, chargeback terms and KPI‑linked rebates for inventory accuracy and on‑time fulfillment.

Strong selection criteria include real‑time WMS with API/EDI, inventory visibility across locations, barcode scanning, cycle‑count reporting, exception workflows, and dashboard KPIs. These capabilities reduce manual reconciliation, speed order routing and improve omnichannel customer experience.
