HEAT Booking is a booking, CRM, and automation platform built specifically for sauna operators. Designed for both private sauna rentals and commercial sauna businesses, HEAT helps operators manage bookings, payments, customer communication, upsells, and daily operations from one system.
With built-in automation for booking flows, payments, customer communication, and smart lock access, HEAT makes it easier for sauna operators to reduce manual work and offer a smooth guest experience. When connected with digital lock systems, sauna guests can receive access automatically based on their booking time—without staff needing to hand out keys or coordinate access manually.

That’s where Inlet comes in.
Inlet provides a secure integration layer between HEAT Booking and supported digital lock systems. Whether you operate a single private sauna, a floating sauna, or multiple commercial sauna locations, Inlet enables automated access control based on confirmed bookings—so guests get access when they need it, and access is revoked when the booking ends.

API-first and lock-agnostic – Connect HEAT Booking to a wide range of supported smart locks
Automated guest access – Issue PIN codes or digital keys based on each sauna booking
Built for sauna operators – Ideal for private sauna rentals, commercial saunas, and self-service wellness concepts
