Key software systems that benefit from integration include Property Management Systems (PMS), Point of Sale (POS), Guest Engagement Platforms, Building Management Systems (BMS/EMS), and analytics tools. Integrations allow real-time data sharing, automated workflows, consistent guest profiles, and centralized control. For example, PMS integration can enable occupancy-based HVAC adjustments, guest preferences carried across systems, and reduced manual data entry. Integration reduces errors, speeds operations, and improves the guest experience across touchpoints.
