We were having a terrible time with double bookings. Airbnb and VRBO would allow the same bookings on the same days — even though I had linked the calendars, it was still happening. Since starting iGMS I have not had a single double booking.Jill F., Owner · Verified review, Capterra

What is a vacation rental channel manager?

A vacation rental channel manager is software that connects your booking channels so availability, rates and reservations stay in step across them. iGMS connects to Airbnb, Vrbo and Booking.com by direct API: when one channel takes a booking, the same dates are blocked on the others straight away. Reservations land in one multi-calendar, next to guest messaging and team tasks.

Real connections, not just calendar links.

A direct API connection means iGMS and the channel talk to each other. A booking on Booking.com blocks the same dates on Airbnb and Vrbo straight away, without waiting for a calendar file to refresh. iCal is a file read on a schedule, and that gap is where double bookings happen, so iGMS uses it only for channels without a direct connection.

Only directly connected channels can be grouped into one property. Make price and availability changes in iGMS: once a listing is connected, iGMS manages them for that channel. Sources: How the channel manager works and the setup guides linked in each row.

Capabilities

What the channel manager does

Multi-calendar with grouped properties and reservations colour-coded by channel

Every booking, every channel, one live calendar.

Group a property's Airbnb, Vrbo and Booking.com listings into one property: one row on the multi-calendar, colour-coded by channel. Block dates for an owner stay and every grouped channel blocks with it.

Booked on Vrbo → Airbnb automatically blockedGrouped property
How grouping works

Push the right rates to the right channels, automatically.

Set your nightly rate and minimum stay once for the whole property, or per channel. Add or subtract a percentage per channel to offset Booking.com's commission, lift Airbnb in peak weeks and keep your direct rate the lowest. Markups apply on top of your dynamic pricing tool.

How channel markups work
iGMS mobile inbox with guest conversations next to a monthly booking calendar

One inbox for guests from every channel.

Airbnb, Vrbo, Booking.com and direct booking messages land in one inbox. Templates and triggers run across all of them, and you can write channel-specific templates where a channel needs different wording.

Explore vacation rental automation

A new booking triggers more than just a calendar block.

A guest books your Vrbo listing at 11pm on a Saturday. iGMS blocks the dates on your other channels, sends the welcome message and schedules the cleaner. You set this up once and it runs on every booking from every channel, with one cleaning task per turnover, not one per channel.

With iGMS, I'm always confident that my calendar is completely synced across platforms, pricing is up to date, my guests are well informed, and my cleaners will always show up.Eric L., Property Manager · Verified review, Capterra

Channel manager or property management system?

A channel manager keeps availability and reservations in step across booking sites. A property management system (PMS) adds the daily work around each stay, such as guest messaging, cleaning, payments and direct bookings. iGMS is both: the multi-calendar, unified inbox and cleaning tasks work from the same reservations.

Hosts who stopped chasing double bookings.

“This system allows me to manage 9 rental properties as easily as managing 1. It links Airbnb and VRBO seamlessly and automates reviewing and notifying guests of any info I was having to manually send out. A must have.”
David L., Owner, 9 properties · Verified review, Capterra · September 2021
“We tried six different PMS systems and none of them were able to accomplish what iGMS did. Everyone else just promised things but never made anything work. We chased double bookings around all day — with this company, we fixed it.”
Juliya M. · Verified review, Trustpilot · March 2026
“Love the simple integration for VRBO, Airbnb and Booking.com. iGMS makes it so easy to have all 3 STR sites active without the fear of double bookings.”

FAQ

Answers before you connect

What is a channel manager for Airbnb?

It is software connected to your Airbnb account that keeps Airbnb reservations, availability and rates in step with your other booking channels. In iGMS, Airbnb reservations appear in the same multi-calendar and inbox as Vrbo and Booking.com.

Will connecting to iGMS change my listings on Airbnb, Vrbo or Booking.com?

Connecting does not rewrite your listings. Your photos, descriptions and reviews stay as they are. Once a listing is connected, iGMS manages its availability, rates and minimum stays, and you can also edit listing details from iGMS if you choose to.

I already link my calendars with iCal. Isn't this the same thing?

No. An iCal link is a file that is re-read on a schedule (iGMS refreshes imported iCal calendars once an hour), which is long enough for two guests to book the same night. A direct connection blocks the dates straight away. If you connect Airbnb, Vrbo or Booking.com directly, remove any iCal links you had set up between those same channels, because running both can block dates twice.

Can I charge a different price on each channel?

Yes, in two ways. Set a rate and minimum stay per channel, or set a percentage markup per channel so every rate moves together, which is how most hosts offset a channel's commission. Markups work on top of a dynamic pricing tool. Make the changes in iGMS rather than on the channel, because iGMS manages rates and availability for connected listings.

I list the same property on three channels. Does that cost me three subscriptions?

No. iGMS counts properties, not listings. When you group a property's Airbnb, Vrbo and Booking.com listings, it counts as one property on your plan. Grouping is also what gives you the single calendar, so it is the first thing to do after connecting.

What about channels you don't connect to directly?

Airbnb, Vrbo and Booking.com connect through a direct API. Others, including Expedia and Tripadvisor, connect by iCal. An iCal calendar still shows its bookings in the multi-calendar and gets automatic cleaning tasks, but it refreshes on a schedule and cannot be grouped into a property.

Which plan includes the channel manager?

All of them. FLEX, PRO and PRO+ include multi-channel sync, the multi-calendar and the unified inbox. Other tools vary by plan, so check the plan comparison on the pricing page.

Can I use iGMS on my phone?

Yes. iGMS has iOS and Android apps for day-to-day rental management, including checking reservations and replying to guests.
