If you're choosing vacation rental software, you've probably narrowed it to two names: iGMS, the flexible per-night-priced toolkit for independent hosts, and Guesty, the enterprise-grade property management platform that grew up serving professional operators. They get compared constantly because Guesty actually sells to both ends of the market — its Lite tier targets 1–3 listing hosts while its Pro tier serves management companies — which puts it in direct competition with iGMS's independent-host sweet spot.

The comparison is trickier than it looks, because Guesty is really two products under one brand. We break down both against iGMS across pricing, transparency, channels, messaging, cleaning operations, direct bookings, and — the factor that decides it for most landlords — which portfolio size each plan is actually built for.

The short answer

Pick iGMS if you host 1–30 short-term rental listings and want software cost that follows your occupancy. Its Flex plan charges $1 per booked night with a $20-per-property monthly minimum, so a dead January costs $20 per listing and you only pay more as bookings prove the model. Pro plans start from about $13 per property per month with published pricing and self-serve signup. Everything operational — multi-calendar, channel manager, unified messaging inbox with AI-driven replies, cleaning and task management, a direct booking engine, and financial reporting — runs from one dashboard. See our full iGMS review (2026) for the plan-by-plan breakdown.

Pick Guesty if you're building toward a professional management operation and want the depth that comes with it: trust accounting, an owner portal, a real CRM, 60+ channel integrations, an open API, and multilingual AI messaging (ReplyAI) across every channel. Guesty Lite covers 1–3 listings with published pricing ($9 per listing per month plus 1% per reservation on the pay-as-you-grow option). Guesty Pro (4–199 listings) is quote-only with a required demo and annual contract — built for teams with staff, not side-portfolio landlords.

The honest bottom line: for 1–3 listings, iGMS and Guesty Lite compete head-to-head and the math usually favors iGMS on slow months. For 4+ listings, the two platforms diverge — iGMS stays self-serve and transparent while Guesty Pro becomes an enterprise sale with enterprise machinery.

iGMS in depth: the independent host's toolkit

iGMS is built around one idea: your software bill should follow your occupancy. The Flex plan charges $1 per booked night with a $20-per-property monthly minimum — a quiet January costs you $20 per listing, while a booked-solid summer costs what it costs because you're earning. Pro plans start from about $13 per property per month, with Pro+ from about $16, suiting hosts who'd rather budget a fixed line item as they scale toward 30 listings.

Everything operational lives in the one dashboard:

• Multi-calendar and channel manager keep Airbnb, Vrbo, and Booking.com availability and rates in sync so double bookings stop happening.
• Unified messaging inbox pulls guest conversations from every channel into one thread with automation rules and AI-driven replies for the routine 80% of questions.
• Cleaning and task management assign turnover jobs, track completion, and keep the crew off your phone — which matters more than any feature once you're past three listings (see our turnover cleaning operations guide).
• Direct booking engine lets guests book off your own site and keep the OTA commission, which is the cheapest revenue lever most hosts underuse.
• Financial reporting tracks revenue per property without a second subscription.
• Integrations with PriceLabs, Beyond, Wheelhouse, DPGO, RemoteLock, Stripe, and Turno cover dynamic pricing, smart locks, payments, and turnover automation.

The strategic case for iGMS is the low fixed cost. A landlord testing whether short-term rentals beat long-term tenants — the classic short-term vs long-term rental decision — can run iGMS on one property for $20 in a dead month and only pay more as bookings prove the model. You're never paying enterprise pricing to find out if the strategy works.

Guesty in depth: two products under one brand

This is where the comparison gets honest: "Guesty" means different things depending on which plan you're on.

Guesty Lite (formerly Guesty for Hosts) is the self-serve product for 1–3 listings. It covers the essentials — multi-calendar, channel sync across Airbnb, Booking.com, and Vrbo, a unified inbox with automated messaging, task automation, payment processing, and a booking website — with published pricing and no sales call. The pay-as-you-grow option ($9 per listing per month plus 1% per reservation) mirrors iGMS's philosophy of paying in proportion to business done, though the 1% reservation fee means high-ADR properties pay meaningfully more than the base rate suggests. Notably, Guesty's AI dynamic-pricing add-on PriceOptimizer is included on Lite for one to three listings, which is genuinely generous — iGMS's built-in rate tools cover basics, but dedicated pricing engines are usually paid extras.

Guesty Pro is the enterprise platform: 4–199 listings (Enterprise covers 200+), quote-only pricing after a demo, annual contracts, and the machinery professional managers need — a real CRM, owner portal, trust accounting, multi-location staff management, 60+ channel integrations, advanced analytics, and a full open API. ReplyAI handles multilingual automated guest messaging across every channel. This is not a product for a landlord with two cabins; it's a product for someone building a management company, and its sales process is designed to filter accordingly.

The practical catch for landlords: Guesty Lite caps at 3 listings. The moment you add a fourth property, you're crossing into Pro's quote-only, annual-contract world — a bigger commitment step than adding a fourth listing on iGMS's published Pro pricing.

The pricing math: when each one wins

Take one property at 50% occupancy — roughly 15 booked nights per month — at a $150 average nightly rate ($2,250 monthly revenue):

• iGMS Flex: 15 booked nights × $1 = $15, which is under the $20 monthly minimum, so you pay $20.
• Guesty Lite pay-as-you-grow: $9 + 1% of $2,250 = $31.50.
• Guesty Lite monthly (flat): $29 per listing.
• Guesty Pro: quote only — but third-party reports put enterprise PMS pricing well above Lite for small portfolios, plus a significant setup fee.

At these figures, iGMS Flex is the cheapest option for a single listing in a normal month. Guesty Lite's flat monthly ($29) or annual ($20) options close the gap for hosts with steady occupancy who'd rather skip the per-reservation fee — run your own ADR against the 1% to see which Lite flavor fits.

The math flips meaningfully at 4+ listings. iGMS Pro's published per-property pricing stays transparent and self-serve, while Guesty Pro becomes a custom quote with annual commitment. If you're growing toward a real management operation — owner reporting, trust accounting, staff coordination — Guesty Pro's depth may justify the enterprise pricing. If you're an independent host scaling a personal portfolio, iGMS's model keeps your software cost predictable and low.

What switching costs to expect

Moving an existing portfolio between platforms is the hidden price of a wrong first pick. With iGMS, the per-night model means trying it on two or three listings is nearly free — connect the channels, import the calendars, and let the unified inbox absorb your guest threads before you migrate the rest. Guesty Lite's self-serve signup is similarly low-friction for 1–3 listings, but the Lite-to-Pro boundary is the trap: growing past three listings forces a sales process, a quote, and an annual contract. Either way, run one platform as the system of record from day one — split operations across two dashboards are how double bookings and missed cleanings happen. If you're starting from scratch, the cheapest experiment is iGMS on Flex for 60 days, then decide whether your portfolio is growing into enterprise territory.

Which should you pick?

• 1–3 listings, testing STR or running a side portfolio: iGMS. Lowest fixed cost in slow months, self-serve signup, published pricing, and no per-reservation fee. Guesty Lite pay-as-you-grow is the honest alternative — worth it if you want PriceOptimizer AI pricing bundled in and your ADR keeps the 1% fee small.
• 3–10 listings, self-managing, growing a personal portfolio: still iGMS for most — Pro's published per-property pricing scales without a sales call. Guesty Pro only enters the picture if you're adding staff and need owner tools.
• 10+ listings, co-hosting for owners, or building a management company: Guesty Pro. The owner portal, trust accounting, CRM, 60+ channels, and open API are built for exactly this — and ReplyAI's multilingual messaging is a genuine edge at scale.
• You mainly want a direct-booking website plus light channel sync: consider a third option — Lodgify publishes its pricing (Basic $18/mo, Starter $33/mo, Professional $58/mo, Ultimate $85/mo for one property on monthly billing, about 20% off annually), offers a 7-day free trial with no card required, and bundles the website builder with channel management.

Guesty Lite's pay-as-you-grow plan costs $9 per listing per month plus 1% of reservation revenue — about $31.50 on $2,250 of monthly revenue. Guesty Pro is quote-only and priced for management companies, well above either.

What is the difference between Guesty Lite and Guesty Pro?

Guesty Lite (formerly Guesty for Hosts) is a self-serve product for 1–3 listings with published pricing and basic automation. Guesty Pro is an enterprise PMS for 4–199 listings with quote-only pricing, a required demo, annual contracts, and professional features — CRM, owner portal, trust accounting, 60+ channels, and an open API.

Does Guesty charge a commission on bookings?

Guesty Lite's pay-as-you-grow plan charges $9 per listing per month plus 1% per reservation. Guesty Pro uses custom quoted pricing (reported as a percentage of revenue plus setup fees by third-party sources). iGMS's Flex plan charges $1 per booked night with no percentage-of-revenue fee.

Which connects to more booking channels, iGMS or Guesty?

Guesty Pro — it offers 60+ channel integrations, among the broadest in the category. iGMS covers the major channels (Airbnb, Vrbo, Booking.com) with multi-calendar sync, which is sufficient for most independent hosts.

Can I use iGMS for long-term rentals?

iGMS is purpose-built for short-term stays — nightly pricing, turnover management, OTA channel sync. For long-term residential tenants, you'd be paying for machinery you don't use; a long-term-focused platform is the better fit.
