Evaluate SLA metrics (OTD, pick accuracy), WMS and API connectivity, returns handling, peak labour scalability, slotting and kitting capabilities, inbound receipt speed, and carrier integrations. Confirm KPI reporting cadence, contingency plans for port disruptions, and visibility to inventory across channels.

Closer proximity reduces drayage, shortens transit windows to national motorways, and improves options for direct container handling or rail freight. That lowers landed cost, shortens lead times for replenishment, and increases flexibility for regional next‑day and same‑day delivery promises.

Require a modern WMS with API/EDI connectivity, real‑time inventory visibility, configurable pick/pack rules, multi‑channel order orchestration, integrated returns processing, and support for value‑added services (kitting, labelling). Verify seasonal workforce sourcing and rapid footprint expansion options.

Negotiate clear rate tables for storage, handling and value‑added services, indexation rules, minimum guarantees, SLA penalties, and carrier pass‑throughs. Confirm access to multiple parcel and pallet carriers, fuel surcharge policies, and breakout scenarios for seasonal volume spikes or contract exit.
