Prioritize SLA metrics (order cycle time, accuracy), warehouse infrastructure (racking, IT/WMS integration), inbound/outbound dock capacity, carrier connectivity, and pricing transparency. Also assess scalability, reverse logistics capability, and security/compliance for regulated products.

Location influences last-mile distance, carrier choice, and LTL/parcel rates. A warehouse nearer main transport corridors shortens transit windows and reduces freight spend. Consider carrier density, average transit days to your customer base, and available service levels (next-day, timed delivery) when modeling landed cost.

Look for omnichannel picking (batch & single-item), zone and wave picking, real-time inventory visibility via WMS APIs, integrated returns processing (RMA workflows), inspection and refurbishment services, and multi-channel order routing to optimize SKU availability and reduce return-to-stock cycle.

Negotiate clear tariff schedules, minimum volume commitments, SLA penalties/rebates, inventory accuracy KPIs, advance notice windows for seasonal peaks, flexible scalability clauses, and data access rights. Include audit provisions and an exit/transition plan to protect continuity.
