Prioritize location (proximity to key demand corridors), warehouse throughput (picks per hour), technology compatibility (WMS/APIs), service breadth (kitting, returns, cross-dock), and documented SLAs for order accuracy and lead times. Also validate carrier partnerships and seasonal scalability to match peak demand.

Perform a network cost model comparing current transit times, freight tiers, and inventory days-of-supply against projected metrics from a Mubende site. Include inbound consolidation savings, reduced last-mile miles, lower holding costs from faster turns, and any changes to carrier rates due to different zone classifications.

Insist on real-time WMS integrations, barcode-driven inventory accuracy, multi-DC routing, returns processing, SLA-backed order cutoffs, and demonstrated carrier integrations for parcel and LTL. Confirm the 3PL’s contingency plans for transport disruption and inventory reconciliation processes.

Conduct site visits, audit sample workflows, request performance KPIs (OTIF, accuracy, lead times), review insurance and liability terms, verify licensing and compliance, and test system integrations. Include a pilot period in contracts with clear KPIs and termination/scale clauses tied to performance.
