A solo host in Lisbon runs three apartments, all on Airbnb, and manages the whole thing from her phone between her day job and the school run. She doesn't want a dashboard with forty tabs. She wants auto-replies that sound like her, a calendar that won't double-book, and a bill that doesn't make her wince. iGMS sells exactly that pitch, and for her, it mostly delivers. The mobile app is genuinely good, the Airbnb automation is sharp, and the pay-per-booked-night plan means a quiet February costs almost nothing.
Then she adds a Booking.com listing. The story gets messier. This review covers what iGMS does well, where it quietly costs you, and which tools fit better once your business stops being Airbnb-only.
What iGMS is
iGMS is a Canadian property management system, founded in 2015, built mobile-first for short-term rental hosts who live on their phones. Its core is Airbnb automation: a direct Airbnb API connection, AI-assisted guest messaging, automated reviews, and team task management for cleaners and co-hosts. It connects to Booking.com and Vrbo too, plus a basic bookable website, but Airbnb is the channel it was built around, and it shows in everything from the sync reliability to the feature depth.

That Airbnb-first focus is the whole thing to understand about iGMS. It's both why the tool feels so polished for Airbnb power users and why it frustrates hosts running a real multi-channel mix. If your business is 80% or more Airbnb, the rest of this review is about whether iGMS's quirks are worth its genuinely fair pricing. If Booking.com and Vrbo carry serious weight in your calendar, a property management system with sturdier multi-channel sync will save you a season of headaches.
Is iGMS worth it for an Airbnb-first host?
Yes — if your bookings come mostly from Airbnb and you run your business from a phone, iGMS is one of the best-value tools in the budget tier. The Airbnb API connection is real-time, the AI messaging handles the repetitive guest questions, and the mobile app earns its 4.8 App Store rating among co-host operators who never open a laptop. For that specific host, little else at this price feels as fluid.
The answer flips the moment Booking.com or Vrbo matter. If a third of your nights come from outside Airbnb, the calendar reliability and the basic direct-booking site become real liabilities. Hold that thought — the next two sections make the trade concrete.
Where iGMS wins
The pay-per-booked-night billing is the standout, and almost nobody else offers it. On the FLEX plan you pay roughly $1 per booked night with a $20-per-property minimum — figures published on iGMS's own pricing page. For a seasonal host whose units sit empty for months, that's the fairest model in the category. You're not paying a flat subscription through a dead winter.
The mobile app is the other genuine win. It's the daily driver for a lot of co-host operators, and the 4.8 App Store rating isn't marketing fluff — reviewers consistently call out that they manage everything from it without touching a desktop. If you run your rentals on the go, that matters more than any feature list.
The Airbnb automation runs deep. AI-assisted guest messaging with auto-translation on the higher tiers handles the "what time is check-in" flood, automated review-sending closes the loop after checkout, and a native dynamic-pricing module ships in several markets without a third-party add-on. For an Airbnb-heavy operator, that's a tight, well-built stack.
Where iGMS falls short
Now the part the feature page won't lead with.
Booking.com and Vrbo sync is the recurring complaint. iGMS is Airbnb-first by design, and the trade is real: G2 and Capterra reviewers repeatedly flag pricing and calendar drift on Booking.com and especially Vrbo, with fixes that arrive slowly. A multi-channel host hits this inside a single high season. We've watched an Airbnb-loyal host bolt on Booking.com for the extra reach, then spend an August Saturday on the phone to a guest she had to relocate because two channels sold the same room — the booking she gained on Booking.com cost her a review and a weekend.
The direct-booking website is basic. It exists, it's bookable, but it keeps iGMS branding by default and the templates feel dated next to a real builder. If commission-free direct bookings are part of your growth plan, you'll want a proper site or widget elsewhere.
The web dashboard lags the mobile app. Several reviewers say the same thing: the app is great, the web reporting feels slow and thin. Once you scale past a couple of units and start wanting real numbers, that gap stings.
And per-property pricing scales unkindly past five units. FLEX is fair for low occupancy, but the PRO plan bills per property every month, so the bill climbs in lockstep with your portfolio.
How much does iGMS actually cost?
iGMS runs two models: FLEX at about $1 per booked night with a $20-per-property minimum, or PRO at roughly $18 per property per month on an annual plan. There's also a free tier for a single property, which is a genuinely useful way to test the workflow before you pay anything.
The catch is the same one that bites every per-property tool: unit six. FLEX stays fair if your occupancy is low and lumpy, but the PRO plan multiplies straight up with your unit count. Six units on PRO annual is about $108 a month — and that number only grows.

Here's how the budget end lines up for a small multi-channel host. The gap opens because BookBed uses flat plan tiers instead of per-property billing, and runs direct APIs on the two channels iGMS handles by iCal:
| What you're comparing | iGMS | BookBed |
|---|---|---|
| Entry price | Free (1 unit) / from ~$18/prop/mo (PRO annual) | €9/mo (Starter, annual) |
| Pricing model | Per property, or $1/booked night (FLEX) | Flat tiers (up to 3 / up to 25) |
| Cost at 8 units (yearly) | over $1,700/year (PRO annual) | €348/year (Pro, up to 25 units) |
| Booking commission | 0% on every plan | 0% on every plan |
| Contract | Month-to-month | Month-to-month |
| Airbnb sync | Real-time (direct API) | Direct API |
| Booking.com sync | iCal, with reported drift | Direct API |
| iCal sync interval | Slower on non-Airbnb channels | 60 seconds |
| Direct booking site | Basic, stays branded | Embeddable widget on your domain |
| Mobile | Native iOS + Android (4.8 stars) | PWA |
| Free trial | 14 days, plus free single-unit tier | 14 days |
The split is clean. iGMS wins on the Airbnb mobile experience, the AI messaging, and the pay-per-night option for seasonal operators. BookBed wins on Booking.com reliability, on flat pricing once you pass a unit or two, and on a direct-booking widget you can actually put your name on. Eight units pay iGMS's per-property tax every month; the same eight fit inside one flat BookBed Pro plan at €29/mo.
iGMS vs the alternatives
No tool wins for everyone. Match it to how you actually book.
If you're 80%-plus Airbnb, phone-first, and you value the pay-per-night FLEX option, stay on iGMS — that's its home turf, and switching would cost you the thing it does best. But if Booking.com or Vrbo carry real weight, or the per-property bill is climbing faster than your revenue, that's the classic reason hosts start shopping for iGMS alternatives. BookBed's 60-second iCal polling and direct Booking.com API close most of the window where two channels sell the same night, the flat Pro tier means unit eight costs the same as unit four, and you can embed a zero-commission direct booking widget on a site that carries your brand, not the software's.
If you're a budget-minded European host who wants the same low price with stronger Booking.com support and EU-based billing, Smoobu is worth a look. If you've outgrown the budget tier entirely — heading past 25 units with owner statements and heavy automation on the list — that's a different, pricier class of PMS, and the full comparison hub lays out who fits where.
So, should you pick iGMS?
For an Airbnb-first host who runs the business from a phone and wants fair, occupancy-friendly billing, yes. The Airbnb API is real-time, the AI messaging earns its keep, the mobile app is the best in the budget tier, and the FLEX plan is the only genuinely seasonal pricing model around. It's a good tool aimed precisely at one kind of host.
But the value cracks the moment your channel mix widens or your unit count grows. The Booking.com and Vrbo sync drift is a real double-booking risk for multi-channel hosts. The direct-booking site won't carry a growth plan. The web dashboard trails the app. And per-property PRO pricing stops being a budget line somewhere around unit six.
Run the math on your own mix before you commit. If you're Airbnb-heavy and staying that way, iGMS is a smart, fair pick. If you're multi-channel, sync-sensitive, or scaling, it's worth comparing what a flat plan with direct Booking.com sync would cost you instead.
About BookBed: Where iGMS handles Booking.com over iCal and bills per property, BookBed runs a direct Booking.com and Airbnb API, polls iCal every 60 seconds, and charges flat plan pricing — €9/mo for up to 3 units, €29/mo for up to 25 — plus a zero-commission widget you can brand as your own.
