HRS (Hotel Reservation Service) is a business-travel focused hotel booking and corporate lodging platform that connects hotels with travelers and travel managers. As an integration, HRS typically enables properties and PMS/CRS/channel ecosystems to distribute rates and availability to HRS, receive reservations, modifications, and cancellations, and support business-travel specific booking conditions such as flexible cancellation policies and negotiated corporate rates.

HRS emphasizes member and corporate benefits (e.g., discounted rates, free cancellation until 6 PM at many hotels, loyalty miles/points earning) and invests in digital guest experience capabilities such as mobile-enabled check-in, check-out, and payment. For hotels, the integration value is primarily incremental demand from business travelers, streamlined reservation delivery into operational systems, and support for corporate travel programs with rate agreements and traveler servicing.
