What is iGMS?
iGMS is vacation-rental software. This page covers the two plans our figures cover, PRO and FLEX; it is not a description of the whole range, and there is at least one tier above them that I have no verified price for. The verified distinction is narrow but important: PRO includes a bookable website and AI replies, while FLEX does not include either capability. Pricing is also calculated differently. PRO is priced per property per month, with the rate per property falling as the property count rises; FLEX is priced per booked night, subject to a monthly minimum for each property.
I read the figures used on this page on September 10, 2026, through a United States connection. That date and location matter because vacation-rental software prices can vary by country. I have therefore treated the displayed United States figures as a dated snapshot rather than assuming they apply indefinitely or in every market.
The available pricing makes the intended account shapes fairly clear without requiring a broader claim about the software. A host can price PRO for 1 property at $48.00 per month, 3 properties at $23.33 each per month, or 10 properties at $17.40 each per month, according to the vendor. FLEX instead costs $1 per booked night with a $20 monthly minimum for each property, according to the same vendor.
That distinction should come before any feature comparison. A per-property plan answers, “How many properties are in the account?” A per-booked-night plan answers, “How many paid nights did those properties generate?” Those are different billing questions, and treating them as interchangeable produces misleading totals.
For example, the vendor’s verified PRO price for 3 properties is not 3 × $48.00. It is 3 × $23.33, which comes to $69.99 per month. The difference between $144.00 and $69.99 is $74.01 per month. That example shows why a review based only on the 1-property card would substantially overstate the price for a 3-property account.
This review stays within what I could verify: pricing at 1, 3 and 10 properties, the billing basis for FLEX, and the two confirmed PRO capabilities. It does not assume unlisted integrations, operational tools or channel coverage. If the underlying question is whether a host needs broad property-management software at all, do you need an Airbnb PMS? separates the software categories before comparing individual products.
That category distinction is useful because hosts often place messaging, calendar control, pricing, cleaning and accounting into one software bucket. They are separate jobs. The Airbnb automation software comparison sorts automation by task. Identify the job first and judge the plan second. I would identify the job first and evaluate the plan second.
How much does iGMS cost?
The billing basis comes first. According to the iGMS pricing page, PRO is charged per property per month on a rate that falls as the property count rises. FLEX is charged at $1 per booked night, with a $20 monthly minimum for each property. FLEX is not a cheaper edition of the same package because the verified plan boundary also differs: it does not include the bookable website or AI replies included with PRO.
| Account size | PRO rate verified from the vendor | PRO monthly arithmetic | FLEX arithmetic from the vendor’s minimum |
|---|---|---|---|
| 1 property | $48.00 per property | 1 × $48.00 = $48.00 | $1 per booked night, never less than $20 for the month: floor $20 |
| 3 properties | $23.33 per property | 3 × $23.33 = $69.99 | $1 per booked night on each property, never less than $20 each: floor $60 |
| 10 properties | $17.40 per property | 10 × $17.40 = $174.00 | $1 per booked night on each property, never less than $20 each: floor $200 |
The 1-property PRO total is straightforward: 1 × $48.00 equals $48.00 per month. The mistake begins when that rate is projected across a larger account. Applying $48.00 to 10 properties would produce $480.00, but the verified 10-property rate is $17.40 each. The correct arithmetic is 10 × $17.40, or $174.00 per month. The incorrect extrapolation is therefore $306.00 higher.
The 3-property calculation sits between those points. At $23.33 per property, PRO totals $69.99 per month. Compared with the vendor’s $48.00 price at 1 property, the property count triples while the total rises by $21.99 rather than tripling. That is the consequence of the falling per-property rate.
FLEX requires a different calculation. At 3 properties, its monthly floor is 3 × $20, or $60. The final charge depends on booked nights because the vendor states a $1 charge per booked night and a $20 minimum for each property. If each of the 3 properties incurs only its minimum, the account total is $60. If the booked-night calculation exceeds a property’s $20 minimum, that property’s booked-night amount determines its charge.
I would not compare $60 for FLEX with $69.99 for PRO and call FLEX categorically cheaper. The verified information establishes that FLEX omits the bookable website and AI replies supplied on PRO. The $9.99 difference at the 3-property minimum therefore compares two plans with different confirmed inclusions.
The 10-property row reverses even the minimum-price ordering. PRO costs 10 × $17.40, or $174.00. FLEX has a minimum of 10 × $20, or $200. PRO is $26.00 below the FLEX minimum at that verified property count, before any FLEX charge above the minimum is considered.
I have not verified a PRO rate for 2, 4, 5, 6, 7, 8 or 9 properties, so I would not draw a straight line between the published points. Nor would I assume the 10-property rate applies above 10 properties. The defensible figures are the three counts the vendor supplied: $48.00 each at 1, $23.33 each at 3 and $17.40 each at 10.
Hosts comparing software costs should also separate subscription expense from the revenue assumptions used to justify it. The rental-arbitrage profitability arithmetic shows how recurring software belongs in a full property model. For demand assumptions, finding Airbnb occupancy rates explains how to research a market rather than inserting an unsupported booked-night estimate.
That matters especially for FLEX because booked nights are part of its billing formula. A host should model the actual nights expected for each property, apply the $1 booked-night charge, and compare the result with the $20 minimum for that property. Combining all booked nights first could hide the fact that the minimum is stated per property rather than once for the whole account.
What do you actually get on each iGMS plan?
The verified feature line contains two capabilities. PRO includes a bookable website and AI replies. FLEX includes neither. I have not added other feature rows because silence in the verified record is not evidence that a capability exists or is absent.
| Verified capability | PRO | FLEX |
|---|---|---|
| Bookable website | Included | Not included |
| AI replies | Included | Not included |
For a concrete 3-property example, PRO costs $69.99 per month based on 3 × $23.33 and includes both verified capabilities. FLEX starts at a $60 monthly minimum based on 3 × $20, but it does not include either one. The minimum difference is $9.99, although the eventual FLEX total depends on booked nights.
The bookable-website inclusion matters only if that is a job the host intends this subscription to perform. A host who already has a suitable booking route may assign little value to another website. A host who specifically wants a bookable website can identify PRO as the verified plan containing it without assuming FLEX offers an add-on or workaround that has not been checked.
The same logic applies to AI replies. They are verified on PRO and absent from FLEX. I have not verified how the replies are configured, where they operate, what inputs they use or whether any usage restriction applies. A responsible plan comparison therefore stops at inclusion rather than turning a two-word capability label into a detailed workflow claim.
This limited table is more useful than a long speculative one. Feature grids often imply certainty by placing ticks and crosses into every row. Here, only 2 rows have been established. If calendar synchronization, pricing, accounting or cleaning coordination determines the purchase — and none of those four is a job we do — the right next step is to ask the vendor directly rather than infer an answer from those 2 rows.
It also helps to define the operational problem before assigning value to AI replies. The Airbnb automated-messages guide distinguishes scheduled communication from other reply workflows. The guest-message template collection helps identify which messages are repetitive enough to standardize. Those decisions can reveal whether AI replies are central to the purchase or merely an additional feature.
A website should receive the same scrutiny. “Bookable” establishes that a booking can be made through it, but the verified record does not establish any further detail I can report. Hosts evaluating a wider platform mix can begin with other apps like Airbnb, then decide whether a separate booking route belongs in their distribution plan.
At 10 properties, PRO’s verified total is $174.00 per month and its per-property rate is $17.40. FLEX cannot cost less than $200 across 10 properties because its minimum is $20 for each property. At that count, PRO provides the two confirmed capabilities while also sitting $26.00 below the FLEX minimum. That is an unusually clear plan boundary based on the verified figures, without requiring assumptions about any unverified feature.
What does iGMS not do?
The only verified absence I can report is plan-specific: FLEX does not include a bookable website or AI replies. PRO includes both. I cannot responsibly expand that statement into a general list of limitations for the software.
For example, at 1 property FLEX has a $20 monthly minimum and PRO costs $48.00, according to the vendor. The $28.00 difference does not prove that FLEX lacks anything beyond the 2 confirmed omissions. It proves only that the billing basis and those verified inclusions differ.
I do not infer absences from an incomplete pricing record. If a function is not covered by the confirmed evidence, the accurate answer is that I have not verified it. That rule is particularly important for channel management, calendar synchronization, direct bookings, pricing, accounting, cleaning and maintenance because each label can encompass several distinct workflows.
A host who needs calendar coordination should frame that requirement directly rather than expecting a plan label to settle it. Syncing Airbnb and VRBO calendars explains the underlying calendar problem, while channel managers for small hosts, a category we do not build, compares it at several account sizes. Neither topic should be treated as settled by the short verified feature list on this page.
The shortest honest limitation section is preferable to a longer invented one. In this case, there are exactly 2 established FLEX omissions and no verified general-product absence worth reporting. Anything more would convert missing evidence into a product claim.
Who is iGMS right for?
I would make this decision from property count, booking pattern and required plan features rather than from a broad verdict. The strongest verified fit is an account that needs a bookable website or AI replies and can price PRO at one of the confirmed counts. The strongest verified case for FLEX is an account that does not need those 2 capabilities and is comfortable with per-booked-night billing subject to the per-property minimum.
Consider Teodor, who operates 10 properties in Zagreb across Airbnb and VRBO. His town, property count and platform mix remain fixed in this example. The vendor’s verified PRO rate at 10 properties is $17.40 each, so his monthly total is 10 × $17.40, or $174.00.
FLEX would have a minimum of 10 × $20, or $200 per month for Teodor’s account. Because $174.00 is $26.00 below $200, PRO is already cheaper than the FLEX minimum at his verified count. PRO also includes the bookable website and AI replies, while FLEX excludes both.
For Teodor, 10 properties is therefore both the count where FLEX stops being the cheaper answer among the verified price points and the count where PRO becomes the obvious price choice between these two plans. I am deliberately limiting that statement to the verified counts of 1, 3 and 10. I have not established the exact crossover at every intermediate property count because those PRO rates have not been verified.
The outcome differs at 3 properties. PRO totals 3 × $23.33, or $69.99. FLEX begins at 3 × $20, or $60, leaving a minimum gap of $9.99. At that count, the choice cannot be made from minimum price alone because FLEX excludes both confirmed PRO features and its final charge depends on booked nights.
At 1 property, PRO is $48.00 and the FLEX minimum is $20. The starting gap is $28.00, but the plans still differ in both billing basis and verified features. A single-property host who needs AI replies or a bookable website would be comparing capability as well as price. A host who needs neither can model FLEX from actual booked nights rather than treating its minimum as the guaranteed final bill.
Portfolio shape also affects the quality of the calculation. Because FLEX applies a $20 minimum to each property, a host should model properties separately. A 3-property account cannot safely be evaluated by taking aggregate booked nights and applying one $20 account-level floor. The confirmed minimum is per property.
Before choosing based on property growth, I would also test whether the operating process is ready for multiple units. Managing Airbnb remotely with multiple listings covers the wider operational structure. For turnover work specifically, sharing a calendar with a cleaner and the vacation-rental task-management comparison help separate staffing needs from guest-reply software.
I would not call the product universally “worth it” from these facts. At 10 properties, the PRO arithmetic is compelling relative to FLEX: $174.00 versus a $200 minimum. At 3 properties, $69.99 versus a $60 minimum leaves feature requirements and booked nights to decide the result. At 1 property, $48.00 versus a $20 minimum makes the same questions even more important.
What do iGMS users say in their reviews?
We do not collect user reviews of other companies, and I will not summarize ratings we did not gather. Readers who want firsthand accounts can consult Capterra’s iGMS review page; I am not repeating a star rating, review count, quoted opinion, pro or con from it.
What this page supplies instead is reproducible pricing at 3 verified counts, read on September 10, 2026, through a United States connection. Those figures are $48.00 for 1 PRO property, $69.99 for 3 based on 3 × $23.33, and $174.00 for 10 based on 10 × $17.40, all according to the vendor.
That evidence answers a different question from a user review. Reviews can describe individual experiences, but the arithmetic here establishes how the confirmed United States price changes with property count and why multiplying $48.00 by every property is wrong. It also keeps FLEX’s $1-per-booked-night basis and $20 per-property minimum separate from PRO’s falling per-property rate.
What should you check before subscribing to iGMS?
I would use the following checklist before entering payment details. It is designed to take about 10 minutes because each item asks for one specific fact or calculation rather than a broad sales demonstration.
- Confirm the billing basis shown for the chosen plan. PRO should be evaluated as a per-property monthly plan whose rate falls with property count. FLEX should be evaluated at $1 per booked night with a $20 monthly minimum for each property, according to the vendor. Do not compare the two as though they use the same unit.
- Check whether the displayed amount assumes yearly billing. The verified record establishes the United States figures used here, but I have not verified a separate monthly-versus-yearly schedule. Ask which billing period produces the displayed rate before using it in a monthly budget.
- Enter the real property count. At 1 property, PRO is $48.00. At 3, it is $23.33 each and $69.99 total. At 10, it is $17.40 each and $174.00 total. I would request a current written total for any other count rather than extrapolate between these points.
- Calculate FLEX property by property. For 3 properties, the combined minimum is 3 × $20, or $60, but each property has its own minimum. Apply the $1 booked-night basis separately and then total the properties.
- Identify whether either confirmed PRO capability is required. The bookable website and AI replies are included on PRO and absent from FLEX. If either one is essential, a FLEX minimum that appears lower at 1 or 3 properties does not represent an equivalent package.
- Ask about every purchase-critical capability not covered here. This review verifies only 2 feature inclusions and the matching FLEX absences. A missing row is not a “no.” It is a question that still needs a documented answer.
- Keep calendar, pricing and accounting requirements separate. A host can use the rate-setting and owner-accounting requirements separately, and the cleaning-app comparison to define those jobs before asking one subscription to cover them.
- Recheck the price immediately before subscribing. The figures here were read on September 10, 2026, through a United States connection. A current checkout total should take precedence if the vendor has changed its pricing since that date.
For a 10-property check, the arithmetic should fit on one line: PRO is 10 × $17.40 = $174.00, while FLEX cannot be below 10 × $20 = $200. That $26.00 difference is large enough to catch a mistaken multiplication or a misunderstood billing basis before purchase.
If the choice is specifically against BnBGenius, our iGMS vs BnBGenius comparison handles that separate decision; BnBGenius Pro costs $10 per month, while the first 500 messages are available with all features and no card. BnBGenius is not a channel manager and does not provide calendar synchronization, direct bookings, pricing tools or owner accounting.
For the technical side of automation choices, automation mistakes new hosts make provides a useful pre-purchase check. The key is to write down the required job, the real property count and the billing unit before comparing totals. At the vendor’s 3-property PRO point, that discipline is the difference between the correct $69.99 calculation and the incorrect $144.00 extrapolation from the 1-property rate.
