Prioritize multimodal access (port, airport, road/rail), WMS and API integrations, inventory visibility, SLA and order‑cycle metrics, scalable footprint and labor plans, capability for returns and value‑added services, and demonstrable carrier partnerships that support your desired transit times and cost targets.

Carrier density and multimodal connectivity reduce both cost and variability: proximity to major ports and Lisbon Airport enables consolidation and feeder services, while efficient road/rail corridors shorten inland transit. This typically lowers last‑mile costs, improves consistency of ETAs, and enables flexible routing for peak demand.

Benchmark base rent and storage per sqm, handling and pick/pack rates, minimum monthly fees, inbound/outbound pallet charges, value‑added service fees, fuel and carrier surcharges, SLA penalties, indexation clauses, and contract flexibility for seasonal scaling or early termination.

Evaluate reverse logistics workflows, dedicated returns processing KPIs, capacity for light assembly and kitting, seasonal labor surge plans, temporary storage options, cross‑dock capabilities, and the 3PL’s WMS support for matrix SKUs and split‑order fulfillment across channels.
