The integrated revenue management system regularly optimizes product offerings, pricing, and occupancy levels. Additionally, it features a system-optimized room assignment that facilitates manual allocations when necessary. One unit can be marketed in multiple ways, whether as a hotel room, an apartment, or a shared hostel space. Housekeeping personnel can update room statuses through a mobile website, which then automatically syncs with the property management system (PMS). Pricing structures are flexible, based on various adjustable criteria such as agents, weekdays, occupancy rates, duration of stay, and lead times. The system accommodates a range of trip lengths, points of contact, and meal plan options all within a single reservation. Invoices can be conveniently divided among different addresses, guests, or billing periods. Services can be created to reflect a percentage of the total invoice or include itemized charges, such as local taxes and credit card processing fees. Notifications regarding room assignments are sent out, enabling the team leader to designate group members to their respective rooms. Furthermore, the entire payment process is conducted online, which is required if a mobile key is to be issued, ensuring a seamless guest experience. This comprehensive approach not only streamlines operations but also enhances customer satisfaction through flexibility and efficient management.
