Prioritize a WMS with API connectors for marketplace and ERP integration, real-time inventory visibility, SLA reporting, and support for kitting, batching and returns. Also assess carrier integrations, cold chain capabilities (if needed), bonded storage, and the provider’s ability to scale labor and space during peak demand.

Proximity to trunk roads and rail reduces inland drayage and transit time, lowering freight spend and inventory in transit. Efficient customs processes and bonded warehousing in Ndola cut border delays and duties timing, improving predictability for regional corridors into DRC and southern Africa.

Negotiate clear SLAs for order accuracy, on-time dispatch, dock-to-delivery times, and claims resolution. Set transparent pricing for receiving, storage per pallet/cubic meter, pick-and-pack, returns processing and value-added services. Include volume tiers, minimum-term commitments and performance-linked incentives or penalties.

Evaluate facility layout, racking types, clear height, power reliability, security controls and dock numbers. Review workforce skill levels for handling SKU proliferation, shift flexibility, training programs and the 3PL’s contingency plans for seasonal peaks or labor shortages to ensure consistent service levels.
