iGMS review

iGMS is aimed at hosts moving from Airbnb only to several channels. It connects Airbnb, Vrbo, Booking.com and a direct website through a multi-calendar and channel manager, with iCal for Expedia, TripAdvisor and other sites. The unified inbox translates guest messages and runs templates with custom triggers, and the PRO tier adds AI-driven replies, an AI agent and an AI property knowledge base. Cleaning management is a strength: tasks can be assigned automatically, cleaners get SMS notices, and there is a cleaner marketplace. The pricing model stands out. FLEX charges $1 per booked night with a $20 per property monthly minimum, which suits hosts with quiet off seasons, while PRO costs $38 per property per month on annual billing for one listing and gets cheaper per property as you add more. After the first property, you only pay for properties once they receive reservations. Owner statements and dynamic pricing sit on the higher plans.
