Prioritize WMS/API compatibility with your OMS, order accuracy and SLA history, carrier connectivity and transit times, returns and reverse‑logistics capability, labor scalability for peak seasons, and value‑added services such as kitting, labeling and customs handling.

Proximity to major highways, rail links and Brussels Airport shortens transit lanes to Benelux, northern France and western Germany, enabling next‑day and same‑day regional delivery windows and better carrier choice for both parcel and palletized shipments.

Central sites typically carry higher rent and labor costs but reduce last‑mile and express carrier spend and improve lead times. Peripheral sites offer lower real‑estate costs and larger footprints but can increase transport time and last‑mile expenses—evaluate based on SKU velocity, order density and delivery promises.

Look for real‑time inventory visibility, robust API/EDI connectivity to OMS and marketplaces, support for batch and wave picking, cross‑dock and returns workflows, configurable business rules for routing and carrier selection, plus reporting and exception management.

Negotiate SLAs for order accuracy, on‑time shipments, inventory accuracy, and lead times; include measurable KPIs, chargeback and penalty clauses, audit rights, insurance limits and clear responsibilities for customs, VAT or duty compliance on international shipments.
