Prioritize transit-time impact to your top delivery ZIPs, carrier density (parcel/LTL options), proximity to ports and highways, warehouse tech (WMS/ASNs), SLA flexibility, labor availability, and total landed cost including drayage and local taxes. Compare sample pick-and-pack rates and integration options with your OMS before advancing.

Carrier connectivity determines daily pickup windows, zone-based parcel costs, and LTL consolidation options. Use transit-time mapping from candidate warehouses to your customer base to quantify two-day and next-day coverage. Factor in first/last-mile partners and peak-season capacity to avoid service degradation.

Key cost drivers: storage density and racking, labor rates, pick/pack pricing, inbound receiving fees, cross-dock charges, and transportation access (drayage/LTL). B2B shippers should model landed cost per SKU across expected velocity bands and include overheads like returns handling and value‑added services.

Typical onboarding: 8–12 weeks for account setup, WMS integration, EDI/API testing, space build-out and SOP alignment. Key checklist items: data migration (SKUs/units), test orders, packing specifications, returns flow, SLAs, and contingency plans for peak periods. Allow extra time for custom compliance or kitting requirements.
