You're reading iGMS reviews because you want one place to handle guest messages, calendars and cleaners, and you've seen that it offers an unusual pay-per-booked-night plan. The question is whether its pricing and features fit the way your rentals actually earn money.
Before reading any review, including this one, pull two things from your own records: the number of booked nights per property for each of the last 12 months, and the share of bookings that came from each channel. Those two lists decide which iGMS plan is cheapest for you, and whether iGMS is the right kind of tool at all.
What does iGMS vacation rental software actually offer?
iGMS is short-term rental software with a channel manager, unified inbox, message automation, cleaning and team task management, a direct booking engine and a mobile app, sold on three plans: FLEX, PRO and PRO+.
On its pricing page, iGMS lists Airbnb, Vrbo, Booking.com and a direct website as channels on all three plans, with Expedia, Tripadvisor and other channels connected by iCal. Its channel manager page describes integration with "the top OTAs, including Airbnb, Vrbo/HomeAway, and Booking.com" and managing other OTAs via iCal.
What each plan adds, per the same pricing page:
- FLEX: channel management, automation, integrations and direct bookings.
- PRO: everything in FLEX plus AI-driven replies, a bookable website, brand management, a property owner portal, and a customer success manager for portfolios of 20 or more properties.
- PRO+: everything in PRO plus message auto-translation, a cash flow report, revenue management, dynamic pricing (listed as available in the US, Canada, Australia, Mexico, the UK and Spain), an AI agent, owner statements and property expense tracking.
White label and a custom domain are listed as an additional fee. The mobile app page describes booking notifications, a unified inbox, calendar edits, review responses and team task assignment from your phone.
Our recommendation: treat the feature list as a starting point and check two things in the trial. First, confirm how each of your channels connects in your account. Second, confirm which plan the features you care about sit on, because several useful ones start at PRO or PRO+.
How much does iGMS cost for your portfolio?
iGMS FLEX costs $1 per booked night with a $20 minimum per property per month. PRO and PRO+ charge a per-property monthly price that falls as your property count rises and is lower on annual billing.
Here are the published per-property prices for a few portfolio sizes, from the iGMS pricing table as of 2026-09-30:
| Properties | PRO monthly | PRO annual | PRO+ monthly | PRO+ annual |
|---|---|---|---|---|
| 1 | $48.00 | $38.00 | $69.00 | $56.00 |
| 3 | $23.33 | $20.67 | $31.33 | $27.67 |
| 8 | $18.00 | $15.75 | $27.88 | $22.13 |
| 20 | $14.20 | $11.35 | $19.25 | $16.00 |
Two billing rules change the real number. On FLEX, iGMS's FAQ says you pay $20 per property for up to 20 booked nights and $1 per night above that, and canceled reservations aren't charged. Its FAQ also says that after the first property you're charged only for properties with at least one confirmed booking that calendar month.
Use this formula for FLEX:
Monthly FLEX cost = sum across properties of the larger of $20 or booked nights × $1
Worked example. Consider a hypothetical three-property host in a seasonal market. In a quiet month the units book 6, 9 and 14 nights. In a peak month they book 27, 29 and 30.
| Month | FLEX | PRO annual (3 × $20.67) |
|---|---|---|
| Quiet (6, 9, 14 nights) | $60 | about $62 |
| Peak (27, 29, 30 nights) | $86 | about $62 |
What this suggests: FLEX and PRO land close together in quiet months, and FLEX costs more once properties fill most of the month. FLEX suits hosts whose units often book under about 20 nights. PRO's per-property price keeps falling as you add properties, so run the table for your own count rather than assuming either plan wins. If you're weighing per-property billing against flat tiers or commission models in general, our guide to vacation rental PMS pricing models walks through the trade-offs.
One more cost rule to know: if you connect to Airbnb through property management software, Airbnb's service fee article says the single host-only fee is mandatory, with most hosts paying 15.5%. That applies to any PMS, not only iGMS, but it belongs in your cost comparison if you're still on the split fee.
What do iGMS reviews miss about fit?
iGMS suits hosts who want messaging automation, team tasks and a mobile app in one tool and whose occupancy makes FLEX or tiered PRO pricing work. It fits less well if you mostly need calendar sync, or if the features you want sit on PRO+.
Use this diagnostic before you start a trial:
| Your situation | What it points to |
|---|---|
| Units often book under 20 nights a month, occupancy swings by season | FLEX is worth pricing out first |
| Units book most nights, 3 or more properties | Compare PRO annual against FLEX with your own numbers |
| You need AI replies, a bookable website or an owner portal | PRO at minimum |
| You need dynamic pricing, auto-translation or owner statements | PRO+, and check dynamic pricing covers your country |
| You want your own domain with no vendor branding | Ask for the white-label fee before you commit |
| You mainly need two calendars to stop clashing | A lighter channel manager may be enough |
| You run over 20 properties with owners to report to | PRO or PRO+, with the customer success manager threshold in mind |
Our recommendation: pick the row that describes the next 12 months, not only today. A host planning to add Booking.com or a direct website next season should test those connections during the trial, not after paying annually.
What should you check during the iGMS trial?
Use the trial to test the connections, costs and features you would depend on in your busiest week, because a feature list can't tell you how the tool behaves with your listings.
- Channel connections. Connect every listing you run and note which ones connect by API-style integration and which by iCal. iCal links update on the fetching platform's schedule. For example, Airbnb imports connected calendars every 3 hours and Booking.com every two hours. Our explainer on iCal vs API sync covers what that gap means for double bookings.
- A test booking. Block a date on one channel and time how long it takes to appear everywhere else.
- Messaging. Set up your check-in and checkout templates and send them to yourself.
- Direct bookings. Check whether the booking page carries iGMS branding on your plan and what a custom domain costs.
- Annual terms. iGMS's FAQ says annual subscriptions under 10 properties are charged upfront, and cancelling early switches you to monthly pricing with the difference charged. Monthly plans have no cancellation fee.
If you're moving from another tool, our checklist for switching vacation rental PMS covers exports and cutover timing.
When this advice does not apply
- Outside USD billing: iGMS publishes prices in US dollars. Your card issuer's conversion will change the effective cost.
- Dynamic pricing outside the listed countries: iGMS dynamic pricing is listed for six countries only. Elsewhere, budget for a third-party pricing tool; its pricing page lists integrations such as PriceLabs, Wheelhouse and Beyond, which charge their own fees.
- Room-by-room rentals: iGMS counts an entire home and its individual rooms as separate properties, which changes every calculation above.
- Large portfolios on annual plans: over 10 properties, iGMS says annual plans are billed monthly under a signed contract. Read that contract rather than relying on this summary.
What to do next
- List booked nights per property for the last 12 months and run the FLEX formula against PRO for your property count.
- Mark which features you need and find the lowest plan that includes all of them.
- In a trial, connect every channel and time a test block across all of them.
- Ask iGMS for the white-label fee if a branded direct booking site matters to you.
- Compare the result with at least one alternative on the iGMS alternatives page before paying annually.
FAQ
What is iGMS pricing for one property?
Its pricing page doesn't list a free plan. It lists a free trial, then FLEX from $20 per property per month or PRO from $38 per property per month on annual billing for one property.
Does iGMS charge booking commission?
The FLEX plan is listed with a 0% booking fee. Payment processing for direct bookings runs through Stripe, which charges its own fees.
Does iGMS work with Booking.com and Vrbo?
Yes. Its pricing page lists Booking.com and Vrbo alongside Airbnb on all plans, with Expedia, Tripadvisor and other channels via iCal. Test the connection with your own listings during the trial.
Calendar sync: BookBed runs two-way iCal sync with Airbnb and Booking.com, so bookings from each channel block the matching dates on the other and on your direct booking calendar. It uses iCal rather than direct APIs, and each OTA fetches calendars on its own schedule. If you're weighing it against iGMS, compare BookBed with the alternatives.
