Which Should You Pick: Boom or iGMS?

Pick Boom if you manage 50+ listings, need AI-driven guest messaging and task generation at scale, and are comfortable with sales-led onboarding and undisclosed pricing.

What each tool does well — and where it falls short
What Boom does well
Deep AI automation across guest comms and operations
Boom's BAM handles guest messaging 24/7, writes review responses, and auto-creates tasks from guest feedback. One operator said their front office team is 'now available to deal with making our guests happy, rather than dealing with repetitive stuff.'
White-glove onboarding and responsive support
Case studies and reviews consistently highlight hands-on migration support. One operator (250 properties) reported full PMS migration completed in one week with 24/7 support, including weekends.
Consolidates multiple tools, potentially cutting software spend
One reviewer reported saving ~$30k/year in add-on software costs after switching to Boom from a previous PMS stack, managing everything in one place.
What iGMS does well
Strong automation that drives real portfolio growth
Users report iGMS helped them grow by over 50% and add new units with less effort. The platform automates guest messaging, reviews, and cleaning management.
Zero commission on direct bookings
Direct bookings through iGMS eliminate OTA fees of up to 17%, allowing property managers to keep significantly more revenue compared to listing exclusively on platforms like Airbnb or Vrbo.
Proven scale across global operations
iGMS manages almost 90,000 property listings across 49+ countries and processes more than 500,000 reservations monthly, demonstrating reliable multi-channel sync at scale.
Where Boom falls short
No public pricing — must contact sales
Boom discloses no pricing on its website and the /pricing URL returns a 404. This makes comparison shopping impossible and suggests custom enterprise-style quoting.
Young product with reported stability issues
Launched around September 2024, two of ten Trustpilot reviews (1-star each) cite bugs and unfinished features. One reviewer warned: 'go for a grown up PMS who have a product that works.'
No built-in direct booking website builder
Unlike Lodgify, Hostaway, and Hospitable, Boom has no native website builder or booking widget. Direct booking sites require a third-party partner integration with ICND.
Where iGMS falls short
Financial reporting is a weak point
95% of reviews on financial reporting say the system offers limited report variations and customizations, making it difficult for operators who need detailed revenue analytics.
No accounting software integration
iGMS lacks built-in accounting features and has no QuickBooks integration, forcing property managers to maintain a completely separate accounting workflow.
Calendar sync reliability concerns
Some users report booking synchronization problems that can lead to double bookings across platforms, which is a serious operational risk for multi-channel hosts.
Which Should You Pick
Pick Boom if
Mid-to-large STR operators (50–360+ listings) who want an AI-first, all-in-one PMS with automated guest comms, dynamic pricing, and white-glove onboarding support.
Skip Boom if
You're a solo host or small operator who needs transparent pricing, a built-in direct booking website builder, or a mature mobile app — Boom has none of these.
Pick iGMS if
Small to medium property managers who want to automate 90% of daily hosting tasks across multiple OTAs like Airbnb, Booking.com, and Vrbo from one unified calendar.
Skip iGMS if
Large-scale operations requiring advanced financial reporting, QuickBooks integration, or enterprise-level team management tools.
Where Boom and iGMS actually differ
- iGMS publishes tiered pricing ($14–$18/property/month) with a pay-per-booked-night option. Boom has no public pricing — prospective customers must book a demo, and its /pricing page returns a 404.
- iGMS is a proven platform managing 90,000+ listings across 49+ countries and processing 500,000+ reservations monthly. Boom launched around September 2024 with $12.7M in funding but has no comparable public scale data.
- Boom's BAM provides AI-powered 24/7 guest messaging, review responses, and auto-generated maintenance tasks from guest feedback. iGMS offers templated automated messaging and review management without a dedicated AI layer.
- iGMS is self-serve with immediate sign-up and concentrates on Airbnb, Vrbo, and Booking.com as direct channels. Boom claims 40+ channel integrations but actual depth is undocumented, and onboarding is white-glove and sales-led.
- iGMS is rated best for small portfolios (1–5 listings) but hits reporting and accounting gaps at scale. Boom explicitly targets 50–360+ listing operators and positions its automation ROI as compounding with portfolio size.
Common objections
- iGMS is cheaper, but will I outgrow it and end up migrating to Boom anyway?
- If you're under 20 listings and your main pain is calendar sync and guest messaging, iGMS handles that today at a known cost. Boom targets 50+ listings — if you're not there yet, you'd be paying for (and onboarding into) a product built for a scale you haven't reached. Revisit when your portfolio and operational complexity actually demand AI-driven task automation.
- Boom can sit on top of my current PMS — could I just add it alongside iGMS instead of choosing?
- Boom does market itself as a layer on top of an existing PMS, but running two platforms creates dual sources of truth for reservations and calendars. Boom's own onboarding process assumes white-glove setup to make the layered model work. For most iGMS users under 50 listings, the added complexity and unknown cost outweigh the AI messaging upside.
