Prioritize WMS functionality and API readiness, pick-and-pack throughput, pick accuracy, SLA lead times, cold-chain availability, cross-dock capability, and inventory visibility. Ask for measured KPIs (OTD, accuracy, cycle time) and sample performance reports to validate operational claims before contracting.

Closer access to Douala and regional highways reduces drayage, shortens inland haul times and lowers variability in transit schedules. That typically cuts buffer inventory needs and enables lower safety-stock levels, improving total landed cost for import-dependent SKUs and speeding replenishment to regional hubs.

Key cost drivers include per-sqm storage rates, labor and handling charges (pick/pack), minimum throughput fees, inbound/outbound accessorials, equipment surcharges, and peak-season pricing. Contract terms to watch: invoice cadence, minimum terms, liability limits, and CPI or fuel surcharge pass-throughs.

Conduct a site visit, request a WMS demonstration and API sandbox access, run test orders, review SLA language and penalties, obtain client references, and validate reporting cadence. Confirm physical security, workforce stability and contingency plans for peak seasons or transport disruptions.
