Evaluate network reach (road/rail access), facility capabilities (racking, security, cold chain), IT/WMS integration, SLA track record, and carrier partnerships. Also validate local labor availability and turnaround metrics for receiving, putaway, and order cycle times.

Model transit using regional trunk road distances to Conakry and scheduled feeder services; include average dwell at consolidation points and seasonal delays. Verify carrier schedules with local truckers and rail operators to produce reliable lead-time windows for planning.

Key drivers: land/lease rates, labor hourly rates, handling productivity (picks per hour), utility and security costs, and last-mile trucking tariffs. Benchmark per-pallet and per-order charges, and require sample cost models for projected volume bands.

Prioritize real-time WMS with API connectivity, barcode/scan-based inventory accuracy, flexible pick-and-pack zones, returns processing, and SLA reporting. Confirm capacity for surge volumes and carrier label/integration requirements for marketplaces and retail partners.
