Prioritize measurable operational KPIs and technical compatibility: on-time pick-and-ship rates, inventory accuracy, average order cycle time, and peak throughput. Verify WMS/TMS integrations, EDI/API capabilities, returns and reverse-logistics processes, and contingency plans for seasonality and labor fluctuations to ensure SLA alignment and predictable cost-to-serve.

Location affects transit times and freight spend: facilities closer to major highways, regional hubs, or rail terminals reduce line-haul and last-mile costs. For omnichannel retailers, placing inventory near high-density customer zones shortens delivery windows and lowers expedited freight usage. Balance inventory placement against inventory carrying costs to optimize overall service and spend.

Migrations commonly follow discovery, integration, testing, and ramp phases. Expect 6–12 weeks for standard WMS integrations and process alignment; more complex SKU assortments or custom systems can extend timelines. Key milestones: requirements mapping, systems integration, pilot orders, staff training, and staged go-live with post-launch performance review and SLA benchmarks.
