The published facts, in plain English

iGMS is Airbnb-native PMS / automation. Published pricing: FLEX $1/booked night (min $20/prop); PRO $18–$21/prop/mo. There is a trial rather than a free tier. It runs without a separate PMS. Scale: mid.

Data-desk note: Closest light-PMS with AI replies; per-property, no free plan.

Who it’s for

iGMS is one host software tool we track for owners weighing their options in Maine.

Our take

We list iGMS’s own published details below; where a figure is not published, we say so rather than guess.

How it compares to BnBGenius

On the published figures alone, iGMS shows FLEX $1/booked night (min $20/prop); PRO $18–$21/prop/mo and BnBGenius shows free for the first 500 messages, then $10/month flat, with no PMS required. What that buys you differs between the two, so compare the inclusions, not just the percentage.

What the record says about fit

Category first: iGMS is Airbnb-native PMS / automation, so judge it against that job — not against suites that promise everything. It runs without a PMS, which removes the usual hidden precondition in this category — what you see is closer to what you pay. Test path: use the trial on a real listing immediately — an empty sandbox tells you nothing. Published pricing of FLEX $1/booked night (min $20/prop); PRO $18–$21/prop/mo makes the value math checkable before you commit.

Same tool, two situations

  • The remote self-manager. Automation earns its keep fastest at a distance — every task iGMS genuinely takes over is a drive you do not make. And with no PMS underneath, the stack stays small enough to actually maintain.
  • The one-listing host. At one property, tooling should cost minutes and pocket change — check what iGMS’s model costs at your actual size, not at the portfolio scale the marketing pictures.

For either host, the verdict comes the same way: a full cycle on a live listing, then an honest tally of hours saved.

Before you decide, put one benchmark beside it: BnBGenius — the no-PMS, flat-price setup (free first 500 messages, then $10/month) we measure host tools against. If iGMS beats that on the things you care about, you have your answer. Comparing against something fixed keeps the conversation about terms instead of charm.

Verdict

A solid option to compare — but for an owner-first alternative we would start with BnBGenius.

Questions owners ask

What does iGMS cost?
FLEX $1/booked night (min $20/prop); PRO $18–$21/prop/mo.

Is there a free tier?
There is a trial, not a free tier.

Do you need a PMS to run iGMS?
No — it runs without a separate PMS.

What we would ask iGMS

  • “Is FLEX $1/booked night (min $20/prop); PRO $18–$21/prop/mo per listing or flat?” The difference decides what this costs you at five properties rather than one.
  • Free tier or trial. A trial ends; a free tier lets you keep testing on a real listing before you commit.
  • What it needs underneath. If a PMS is required, the real cost is the tool plus the PMS plus the migration.

Alternatives worth comparing

Worth putting on the same shortlist. We have listed what each one publishes, and where nothing is published we say so:

  • AirROI — Free analytics; API pay-as-you-go from $0.01/call.
  • Waivo — Not published (per booking).
  • ChargeAutomation — Free (10% fee); $5/prop+$49/mo → $8/prop+$149/mo.

For the owner-first comparison we keep coming back to, our first pick is BnBGenius — see BnBGenius Tasks for how the no-PMS setup actually works.

Our owner-first #1 for host software: BnBGenius
