Prioritize measurable service levels: on-time pick/pack SLA, order cycle times, and inventory accuracy. Evaluate WMS and carrier integrations, returns capability, customs handling experience for cross-border shipments, scalability of labor and space, and transparent cost structures that separate storage, throughput, and value-added services.

Rivera’s border position can lower last‑mile transit but introduces customs and tariff variables. Work with 3PLs that provide customs brokerage, bonded storage options, and carriers experienced in cross-border documentation. Strategic staging of inventory in Rivera can reduce inland transport but requires coordinated duty and compliance planning.

Require a cloud WMS with real-time inventory, API or EDI integrations to major carriers and your eCommerce platforms, barcode/lot tracking, and reporting dashboards. Look for automated replenishment signals, returns processing workflows, and exception management to maintain SLA compliance across channels.

Common models include per-pallet or per-sqft storage, pick/pack per-line fees, and throughput-based handling charges. Negotiate minimums, volume tier discounts, clear SLA penalties, seasonal rate cadences, and short pilot periods. Include flexibility clauses for labor peaks and rate reviews tied to defined indices to control cost exposure.
