iGMS is short-term rental software for independent hosts and property managers who list on Airbnb, Vrbo and Booking.com. It brings bookings, calendars and guest messages into one app, so a host does not have to log in to each platform separately. The company behind it, AirGMS Technologies Inc., launched in 2015 and is bootstrapped.
According to iGMS, the platform has managed 399,536 listings across 133 countries and sent 19,568,104 messages. The homepage shows a 4.8 rating from more than 3,000 hosts, and the iOS app is listed at 4.7 on the App Store. These figures come from the company itself, not an independent source.
Setup follows three steps on the site. A host links Airbnb, Vrbo or Booking.com accounts, which the company says takes about two minutes each. Calendars, messages and bookings from every platform then sync automatically into one app, color-coded by source so each reservation's origin is clear.
From there, the host works in a single inbox and calendar on the web or the mobile app. Replies, booking checks and cleaning coordination happen in one place. Other channels such as Expedia and TripAdvisor connect through iCal, and the company says a real person helps if a user gets stuck during setup.
The unified inbox collects guest messages from all connected platforms and uses AI to suggest replies. Message templates, custom automation triggers and review automation cover routine communication. The multi-calendar and channel manager keep availability in sync and aim to prevent double bookings.
On the operations side, iGMS offers cleaning task auto-assignment, checklists, SMS notifications to cleaners and shared access for staff, co-hosts and owners. Direct booking tools include a website builder, booking engine, coupon codes and Stripe payments. PRO+ adds dynamic pricing, cash flow reports, owner statements and AI tools.

Yes. New accounts get a 14-day free trial with no credit card required. The site also lists a Free Plan pilot at $0 a month, with a 4% fee only on direct payments.
iGMS connects to Airbnb, Vrbo and Booking.com, and supports iCal for other channels such as Expedia and TripAdvisor. It is also an official Google Vacation Rentals partner and offers a WordPress direct booking plugin.
After the first property, iGMS charges only for properties with at least one confirmed booking in the calendar month, with a minimum equal to one property. Listings of the same property on several platforms must be grouped through the channel manager to count as one.
The site positions iGMS for independent hosts, including those managing 2 to 8 properties. The usage-based FLEX plan and per-property pricing make it workable for small portfolios, and a mobile app supports managing rentals on the go.
Dynamic pricing and revenue management are included on PRO+ and listed as available in the US, CA, AU, MX, UK and ES. iGMS also integrates with PriceLabs, Wheelhouse, Beyond and DPGO.
Monthly subscribers pay no cancellation fees. If an annual subscription is canceled early, the plan switches to monthly pricing and the difference for the months used is charged.
