✓Editorial verdict
Which should you pick: iGMS or Boom?
Pick iGMS if you want transparent per-listing pricing starting at $14/mo and can self-serve onboarding for 2–20 listings. Pick Boom if you manage 50+ listings, are already stitching together separate tools for messaging, pricing, and task management, and are willing to go through a sales-led process for an AI-first PMS layer.

What each tool does well — and where it falls short
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.
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.
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.
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.
Which should you pick
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.
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.
Where iGMS and Boom actually differ
- iGMS publishes pricing ($14–17/listing/mo) and lets you sign up online. Boom is quote-only with no public pricing and a sales-led onboarding.
- Boom's core pitch is AI-first automation — BAM for 24/7 guest messaging and review responses, plus AI-generated tasks from guest feedback. iGMS offers templated guest messaging and basic automations without a dedicated AI layer.
- Boom claims 40+ channel connections and can operate as a standalone PMS or as an enhancement layer on top of an existing PMS. iGMS concentrates on Airbnb, Vrbo, and Booking.com with 40+ integrations, but is not designed to sit on top of another PMS.
- Boom offers white-glove onboarding and migration support as part of its enterprise motion. iGMS is self-serve with documentation and standard support — no dedicated migration team.
- iGMS has a public track record — 90,000+ listings, 49+ countries, 500K+ reservations/month. Boom is a younger, mid-to-large-operator-focused product with less public scale data and explicit 'early-stage rough edges' in its own worth-it guidance.
Common objections
- Boom's AI messaging sounds better than iGMS's templates — isn't that worth the premium?
- For a large operator drowning in inbox volume, possibly. But Boom's pricing is opaque, and the actual cost vs. iGMS Pro ($17/listing) is unknown until you talk to sales. If AI messaging is your only pain, Hospitable publishes $29/mo + $10/property with Airbnb Preferred+ status, which is a more transparent comparison than Boom.
- Boom can layer on top of my existing PMS — doesn't that make switching cheaper than ripping out iGMS?
- It can, in theory. In practice, running two platforms means two sources of truth for reservations and two monthly fees, and Boom's own materials suggest white-glove onboarding is needed to make the layered model work. If you're already on iGMS and it's doing its job, adding Boom on top is usually a worse trade than migrating to a single platform once.
