Evaluate port proximity, RoRo ferry frequency, and inter-island carrier schedules. Check 3PL access to consolidation services, cross-dock capabilities, and connections to major hubs like Cebu and Dumaguete. Confirm transit time variability and contingency routing for weather-disrupted sailings.

Focus on total landed cost—storage, handling, inbound/outbound shipping, and seasonal surcharges. Require clear SLAs for picking accuracy, order lead time, and claims. Request detailed cost models for peak-season volume and defined penalties or remediation terms for missed SLAs.

Look for a proven WMS with API-based integrations to your eCommerce platforms and TMS. Key features: real-time inventory visibility, batch and expiry control, barcode scanning, and automated order routing. Ask for examples of prior integrations and data exchange cadence.

Seasonality increases demand volatility and shortens lead times; plan with buffer stock and flexible labor/space commitments. Consider temporary storage ramps and staggered replenishment. Use demand forecasting tied to tourism calendars and require scalable pick/pack resources from your 3PL.

Compare transit time to primary customer clusters, frequency of feeder sailings, and total cost-to-serve. Assess infrastructure (covered racking, security, cold storage if needed), labor availability, WMS maturity, and the 3PL’s contingency plans for maritime disruptions. Prioritize partners with transparent metrics and experience handling multi-island logistics.
