The math that drives every short-term rental landlord's software decision is the platform tax: Airbnb's guest fees, Vrbo's commissions, Booking.com's cut. A good channel manager doesn't just sync calendars — it gives you the automation and direct-booking tools to claw back some of that margin. Pick the wrong one and you're paying a monthly fee for a calendar you could have synced free.

Two platforms dominate the conversation for independent hosts and small portfolios, and they come from opposite design philosophies. iGMS is the flexibility-first platform: per-night Flex pricing that scales with occupancy, AI-assisted guest messaging, a built-in website builder, and features bundled into every plan. OwnerRez is the operator's platform: flat per-property monthly pricing with zero booking fees, the segment's highest user ratings, and a built-in legal layer of rental agreements and guest signatures. Here's the honest comparison, with pricing drawn from 2026 sources.

The Quick Verdict

Choose iGMS if you want pricing that breathes with your occupancy — the Flex plan charges $1 per booked night with a $20-per-property monthly minimum, so a slow month costs you almost nothing. With automated guest messaging, a unified inbox, cleaning and team management, a website builder, payment processing, and financial reporting bundled in, it's the pick for the landlord testing short-term rentals or running a seasonal property.

Choose OwnerRez if you want flat, predictable costs and the strongest legal layer in the segment — around $40/month for one property on a sliding scale that drops per-property as you grow, with zero booking fees and digital rental agreements with guest signatures included in the base price. It's the pick for the detail-oriented operator who runs direct bookings and wants contracts handled without a third-party tool.

The one-line version: iGMS sells flexibility — pay for what you book; OwnerRez sells control — flat pricing, no booking fees, and legal agreements built in. Seasonal or testing leans iGMS; established and direct-booking-focused leans OwnerRez.

iGMS: The Flexibility-First Platform

iGMS (founded 2015) is built for individual Airbnb and Vrbo hosts and small managers running 1–50 listings. Its signature move is pricing choice: Flex, Pro, and the newer Pro+ tiers plus a custom enterprise tier.

The plans (per igms.com/pricing, verified October 2026):

• Flex — $1 per booked night, minimum $20 per property per month. Unlimited properties. You only pay for nights with actual reservations (canceled reservations aren't charged), and properties are billed as active if they had a booking during the period. Includes the full feature set: all channels, automated reviews, revenue management, financial reports, dynamic pricing, owner access — even the add-on features.
• Pro — volume ladder: monthly billing runs $48/property/mo for 1 property down to $17.40/property/mo at 10 properties; annual billing drops those to $38 and $15/property/mo respectively. Unlimited properties; full channel coverage (Airbnb, Booking.com, Vrbo/HomeAway) plus automated reviews, revenue management, financial reports, and dynamic pricing.
• Pro+ — the newest top tier: $69 per property per month for 1 property on monthly billing ($56 on annual billing).
• Enterprise — custom pricing for 30+ properties, with phone support and a dedicated success manager.

Note: iGMS's old Lite entry tier ($14/property/mo) no longer appears on its pricing page — Flex is now the entry-level option.

There's a free 14-day trial, free setup, and no cancellation fees — the whole pricing philosophy is low-commitment.

The feature stack is broad for the price: AI-assisted messaging automation with templates, a unified inbox across channels, a multi-calendar, automated review requests, cleaning and key-exchange management, team management with task assignment, a website builder for direct bookings, Stripe-based payment processing, and financial reporting across properties. iGMS explicitly serves hosts prioritizing Airbnb and Vrbo over traditional hotel channels.

The trade-off: iGMS is not a long-term residential tool — it's purpose-built for short-term and mid-term rentals. And the Flex plan's per-night math only wins when occupancy is low to moderate; at full occupancy on several properties, Pro's flat rate can be cheaper. Run both numbers for your actual booked nights.

OwnerRez: The Operator's Platform

OwnerRez is the highest user-rated platform in the vacation rental software segment — third-party aggregators show it at or near the top of the category (one 2026 comparison cites a 5.0/5 G2 rating and 4.9/5 on Capterra), a reputation earned by building for technically capable hosts rather than for the broadest market.

The pricing model: flat monthly, per-property, on a sliding scale — roughly $40/month for one property, with the per-property cost decreasing as you add listings (one 2026 comparison puts five properties at $88/month). Zero booking fees. No setup fees, no contracts, and a 14-day trial.

The channel manager syncs Airbnb, Vrbo, Booking.com, and Google Vacation Rentals via API — real-time sync of rates, availability, photos, and rules — plus dozens of smaller OTAs. But OwnerRez's most differentiated feature isn't channel management at all: it's the legal layer. Customizable digital rental agreements with signed PDFs for every guest are included in the base price. For a landlord running direct bookings, that's a contract tool most competitors charge extra for or punt to a third party.

Other standouts: hosted property websites with custom domains (plus a WordPress plugin), unlimited team logins, included SMS messaging, centralized guest communication with a guest guide, owner statements and accounting with QuickBooks sync, and detailed availability and rate management.

The trade-offs are real: the interface has a steeper learning curve than iGMS — power users love it, first-timers can find it overwhelming. OwnerRez has no native dynamic pricing engine; you connect PriceLabs, Beyond, or Wheelhouse, which adds cost and setup. And it has fewer total channel integrations than the enterprise-grade managers — fine for Airbnb/Vrbo/Booking.com hosts, a limitation if you distribute widely.

The Pricing Math: 1 Property, 5 Properties, 15 Booked Nights

This is where the two philosophies collide. Using 2026 published figures:

One property, 15 booked nights in the month. iGMS Flex: $20 (the $15 in per-night charges sits under the $20 minimum). OwnerRez: ~$40. iGMS wins by half — Flex's minimum is simply cheaper than a flat plan at low occupancy.

One property, 28 booked nights. iGMS Flex: $28. iGMS Pro (annual): $38. OwnerRez: ~$40. At high occupancy, iGMS Pro's flat $38/month still undercuts both — this is the crossover most hosts miss: Flex is for variable occupancy, Pro is for full calendars. The margin is thinner than the old ladder-tail numbers suggested, so price your actual booked nights.

Five properties, moderate occupancy. iGMS Pro (annual): ~$87 (5 × $17.40). OwnerRez: ~$88 (per 2026 third-party comparisons). Dead heat — at this scale the decision stops being about price and starts being about features: OwnerRez's legal agreements and zero-booking-fee model vs. iGMS's included automation add-ons and simpler onboarding.

The booking-fee footnote. Neither platform charges per-booking fees — OwnerRez explicitly, iGMS implicitly (per-night billing is a subscription, not a commission). Compare that against commission-based managers that take 1–2% of bookings: on $10,000/month in bookings, that's $100–$200/month saved by either platform here. Both win; the question is only which pricing shape fits your occupancy pattern.

Guest Messaging: Automation Depth

This is the daily-grind feature — the one you'll touch more than any other. iGMS leads with AI-assisted messaging automation: routine guest interactions (check-in instructions, checkout reminders, mid-stay check-ups) handled automatically from templates, all flowing through a unified inbox across channels. For a landlord managing STRs alongside a day job, this is the feature that prevents the 11 PM "what's the Wi-Fi password?" message from ruining your evening.

OwnerRez counters with a centralized inbox, customizable guest guide, and included SMS messaging — solid, reliable, and arguably more controllable, but without iGMS's AI layer doing the first pass. OwnerRez's Rezzy AI exists as an add-on for hosts who want the automation. If you want messaging that mostly runs itself out of the box, iGMS. If you want to script every touchpoint yourself and keep humans in the loop, OwnerRez's tooling is deeper.

Direct Bookings: Cutting the Platform Tax

Both platforms offer direct-booking websites, which is how you escape the 14–16% combined platform fees — but they package them differently. iGMS includes its website builder and direct booking management in every plan. OwnerRez offers hosted property websites with custom domains and a WordPress plugin across plans, with the direct booking engine as part of its toolkit (note: some 2026 comparisons flag the booking site as an add-on — verify what's included at your plan level before committing).

The deeper point: OwnerRez's included rental agreements are what make its direct bookings work for landlords. Taking a booking directly means you own the guest relationship — and the liability. Signed digital agreements on every direct booking, without paying for a separate e-signature tool, is the kind of unglamorous feature that prevents the dispute that costs you a month's revenue. iGMS covers direct bookings well operationally; OwnerRez covers them legally.

Accounting, Owner Statements, and Cleaning Operations

If you co-own properties or report to investor partners, accounting matters. iGMS includes financial reports (reservations, work orders, transaction history, summaries) and owner access across plans, with revenue management and dynamic pricing built in on Flex and Pro. OwnerRez offers owner statements and accounting with QuickBooks sync — the more mature accounting story, especially if your books live in QuickBooks already.

On operations, both handle the turnover workflow: iGMS bundles cleaning and key-exchange management with team task assignment and productivity add-ons (included on Flex/Pro); OwnerRez covers task management and team coordination with unlimited team logins — no per-seat fees as your cleaner roster grows. For a 1–5 property landlord with one or two cleaners, both are more than adequate; the difference only shows at 10+ properties with layered teams.

The Verdict by Landlord Type

The testing-the-waters landlord (1 property, trying STR for a season). iGMS Flex. The $20 minimum means your software cost tracks your occupancy, and a slow first month doesn't punish you with a $40 flat fee. Free 14-day trial, no cancellation fees — the whole product is designed for exactly this experiment.

The established 2–5 property STR operator. A genuine toss-up on price (~$87 vs. ~$88 at five properties on annual billing). Choose iGMS if guest-messaging automation and included dynamic pricing matter most; choose OwnerRez if you take direct bookings and want the rental-agreement legal layer plus QuickBooks-synced owner statements. Expect a steeper learning curve with OwnerRez — budget a weekend for setup.

The 10+ property manager. OwnerRez, with a pricing check. The sliding per-property scale keeps dropping, zero booking fees compound at volume, and unlimited team logins plus the legal layer are built for operations with staff. iGMS Enterprise is the alternative if your team lives in its automation workflows — get both quotes at your exact property count.

The landlord who also runs long-term rentals. Neither — and that's the honest answer. Both platforms are short-term/mid-term specialists. Your long-term units belong in a residential manager; use one of these only for the STR side of the portfolio.

Frequently Asked Questions

Is iGMS or OwnerRez cheaper for one vacation rental?

At 2026 published pricing, iGMS is cheaper at low-to-moderate occupancy: Flex costs $1 per booked night with a $20 monthly minimum, versus OwnerRez at roughly $40/month for one property. At high occupancy (25+ booked nights), iGMS Pro's flat $38/month (billed annually) undercuts both. Price your actual booked nights on both plans.

Do either charge booking fees?

No — and that's a key reason both appear in this comparison. OwnerRez charges a flat monthly rate with zero booking fees; iGMS charges per-night or per-property subscription fees, not commissions. Either one saves you the 1–2% booking commissions that commission-based managers take.

Which is better for direct bookings?

Both offer direct-booking websites, but OwnerRez has the stronger legal story: digital rental agreements with guest signatures are included in the base price, which matters when you own the guest relationship directly. iGMS includes its website builder on every plan and is simpler to launch. Verify the current plan-level inclusions on both sites before committing.

Does OwnerRez have dynamic pricing built in?

No — OwnerRez has no native dynamic pricing engine. You integrate a third-party tool like PriceLabs, Beyond, or Wheelhouse, which adds subscription cost and setup time. iGMS includes dynamic pricing and revenue management on its Flex and Pro plans. If automated rate optimization is a must-have, this is iGMS's clearest feature win.

Can I use iGMS or OwnerRez for long-term rentals?

Not well. iGMS is explicitly built for short-term and mid-term rentals, and OwnerRez is a vacation-rental channel manager — neither handles long-term leases, tenant screening, or monthly rent collection the way a residential property manager does. Use them for the STR units only.

Which has the easier learning curve?

iGMS, by most accounts — it's designed for individual hosts getting started, with a free trial and no setup fees. OwnerRez is the more powerful platform but has a steeper learning curve; technically inclined operators love it, first-timers should budget real setup time. Both offer trials, so test-drive the interface before committing.

What happens if I cancel mid-season?

iGMS charges no cancellation fees, and the Flex plan means a canceled season costs you little beyond the monthly minimums on active properties. OwnerRez has no contracts. Either way, export your guest data, forward your direct-booking domain, and update your OTA listings before you pull the plug — the software exit is easy, the listing transition is where hosts get burned.
