Prioritize inventory accuracy, order processing speed, carrier integrations (parcel and pallet), returns handling, and scalability of pick/pack operations. Also evaluate technology (WMS + API), cross‑dock capacity, and same‑day cutoffs to align with your SLAs and peak seasonal demand.

Closer proximity reduces drayage, inbound lead times, and multimodal handling costs; motorway access lowers trunking miles and improves route flexibility for last‑mile. Factor port handling windows and terminal access times into transit cost models when comparing providers.

Compare dock doors per 10,000 sq ft, yard depth, clear height, racking density, on‑site staging, segregation for returns, power for automation, and rail/port connectivity. These operational metrics drive throughput, labor productivity, and space utilization.

Onboarding typically ranges 6–12 weeks depending on SKU complexity, EDI/WMS integrations and inventory transfer. Expect initial productivity ramp and QA cycles; mature operations can deliver next‑day UK coverage and regional same‑day options through parcel hubs.

Model fixed vs variable warehousing costs, inbound consolidation, drayage, inventory carrying, pick/pack labor, packaging, parcel vs pallet pricing, and penalty/chargeback exposure. Include scenario analysis for peak season volume and returns to compare true landed cost across providers.
