Assess SLA metrics (OTD, order accuracy), WMS integration and API support, picking technology, returns processing, multi-temperature capacity, and ability to provide value-added services. Request throughput data, peak-season performance, KPIs and client references to validate operational consistency.

Armagh offers direct links to major trunk roads and reasonable proximity to Belfast and Larne ports, improving transit times to both UK and Irish customers. Multiple carrier lanes and regional haulers serve the area, enabling flexible routing and cost-optimized LTL and full-truckload options.

Typical cost components include storage per pallet or cubic metre, pick-and-pack fees, inbound receiving and put-away, handling for value-added services, climate-control premiums, labour surcharges and fuel/carrier pass-throughs. Look for activity-based vs throughput-based pricing and minimums that affect ROI for seasonal volumes.

Validate access to temporary labour pools, seasonal warehouse bays, overflow cross-dock capacity and contingency carrier agreements. Review the 3PL's historical peak metrics, WMS flexibility for surge SKUs, and ability to deploy slotting and temporary automation to maintain SLAs.

Confirm customs brokerage capabilities, EORI and VAT handling, bonded storage options if needed, accurate export documentation and experience with Northern Ireland Protocol implications. Ensure the 3PL integrates customs data with shipments and provides audit-ready records for cross-border audits.
