Prioritize measurable metrics: dock doors per 1,000 sqm, pick density and SKU slotting, average picks per hour, inventory accuracy, labour scalability, and carrier access. Require WMS/API connectivity, SLA turnaround times, returns processing capability, and visibility into pick/pack costs to compare true landed cost and service performance.

B2B pallet models focus on pallet storage rates, monthly minimums and pallet handling fees. eCommerce models add pick-and-pack fees per order/line, cartonization, kitting and returns handling. Common drivers: inbound handling, slotting density, labour (seasonality), minimum charges and value-added services like labeling or QA.

Carrier options include daily RoRo/ferry, express parcel and national LTL networks. Typical lead times: next-day to major GB metros (subject to cutoffs), 1–2 days to ROI, and 2–5 days to EU depending on routing and customs. Plan for customs clearance time for intra-EU/GB flows and maintain buffer for peak periods.

Require a modern WMS with real-time inventory, order batching, barcode scanning and returns module. Verify API or EDI connections to your OMS/ecommerce platforms, automated ASN/inbound reconciliation, reporting dashboards, and support for carrier integrations and rate shopping to enable accurate cutoffs and shipment visibility.

Assess 3PL customs expertise: in-house brokers, bonded storage, documentation for EORI and VAT, and experience with DDP/DAP flows. Confirm processes for export declarations, commodity classification, and duty mitigation. Choose partners that can demonstrate compliant cross-border workflows and systems integration with customs agents.
