iGMS vs Hospitable vs Smartbnb: Small-Host PMS Guide 2026

Smartbnb and Hospitable are the same product. The company rebranded Smartbnb to Hospitable in 2021, then absorbed the old name into the new one. So when a forum thread pits "Smartbnb vs Hospitable," the answer is: pick a date. Anything before mid-2021 is Smartbnb. After that, it is Hospitable. The real fight, for a host with 1 to 10 units, is iGMS vs Hospitable, and the deciding factor is not features. It is which messaging engine breaks less often at 2 a.m.

The Smartbnb and Hospitable Confusion, Cleared

Smartbnb launched as a messaging automation tool focused on Airbnb. The team rebranded to Hospitable Technologies in 2021, then folded the Smartbnb brand into Hospitable.com. If you find a 2020 review raving about Smartbnb's auto-messages, that review is about today's Hospitable. The product line is continuous.

This matters because old comparison posts still rank. A new host reads three articles and thinks they are choosing between three products. They are choosing between two: iGMS and Hospitable. That is the entire field for the small-host tier.

The other small-host name you see is Hostfully, which is a different company with a different focus (guidebooks plus PMS). It is not a Smartbnb successor. Do not let the URL trail confuse you.

What Each One Does at the Core

iGMS started as a multi-calendar tool for Airbnb power users. It stayed close to that root. Hospitable started as messaging automation and grew outward. Both now do calendar sync, message rules, team tasks, and direct booking sites. The shapes are similar. The defaults are not.

Feature Comparison That Actually Matters

Forget the marketing site checklists. Both vendors check most of the same boxes. The differences live in three places: messaging logic, channel reliability, and pricing per listing.

Read that table once. Then read it again with this filter: which of these will I actually use this quarter? If the answer is "messages, calendar, cleaner notifications," you do not need a $29 plan. You need the $14 plan to not break.

Where iGMS Wins

Price. A host with 2 units paying $14 each saves real money against Hospitable's per-listing rate. Over 12 months on 5 units, that gap is $900 or more. iGMS also has a more forgiving free tier for hosts testing the workflow before they pay.

Where Hospitable Wins

Setup speed and message quality out of the box. Hospitable's default templates handle 80% of guest questions on day one. iGMS asks you to build more of that yourself. If your time is worth $50 an hour and setup takes you 6 extra hours, the math flips.

Messaging Automation Is the Real Product

Both tools sync calendars. Both push prices from a connected revenue tool. The thing you actually buy a small-host PMS for is messaging that does not embarrass you.

A guest sends "what time is checkout?" at 11 p.m. on a Tuesday. The PMS either answers within 60 seconds with the right time, or it does not. That is the product. Everything else is a calendar widget.

Hospitable's AI guesses guest intent and drafts a reply. You approve it or let it auto-send. iGMS leans on rule templates: trigger plus action, like "if booking confirmed, send welcome message at 4 p.m. day before check-in." Rule logic is more predictable. AI drafting is faster to set up but harder to audit.

The Auto-Send Trap

New hosts turn on full auto-send and stop reading messages. Three weeks in, a guest reports a broken AC, the AI replies with the check-in code, and the review tanks. Both products have this failure mode. Auto-send is a feature, not a strategy. Read your inbox daily for the first 90 days. More on keeping voice in automated messages.

Pricing Tools and the PMS Boundary

Neither iGMS nor Hospitable is a pricing engine. Both connect to PriceLabs, Wheelhouse, or Beyond. A small host who treats the PMS as the pricing tool is going to leave money on the table. Pick a pricing tool separately, then connect it.

The bigger question is when to override the pricing tool. Software is pattern-matching. You know things the model does not, like a local festival or a competitor relisting at half price. Override rules belong in your head, not in the PMS.

I launched a two-bedroom in a soft Ohio market last spring at 18 percent below the lowest comparable active listing. The first eight bookings cost me about $600 against my target. By month four I had 31 reviews and an actual ADR 12 percent above my launch price, within 6 percent of the target I had retuned upward once review velocity kicked in. The PMS did none of that math. PriceLabs did the daily moves. The PMS just sent the messages and kept the cleaner on schedule.

Connect, Do Not Combine

Use the PMS for messaging, tasks, and unified inbox. Use the pricing tool for daily rate moves. Use your own brain for strategy calls. Three layers. Do not let any vendor sell you on collapsing them.

Decision Framework by Listing Count

Your unit count drives the answer more than any feature comparison.

The trial-period support test is real. Email each vendor a question that requires a thoughtful reply, like "how do I handle a dispute message that the AI misread?" Whoever answers in under 4 hours with a real human is the one you sign with.

When to Walk Away From Both

If you have one listing and you are still figuring out whether the market works, you do not need a PMS yet. The Airbnb native inbox plus a saved-replies cheat sheet covers you for the first 30 bookings. Knowing when a market is wrong matters more than your tool stack.

Migration Reality and Switching Costs

Switching PMS tools is not a 20-minute job. You disconnect the Airbnb API on one side, reconnect on the other, rebuild every message rule, reattach your pricing tool, and re-invite your cleaning team. Plan a full weekend. Expect at least one missed message during the cutover.

The data does not migrate cleanly either. Past guest threads stay on the old platform. Your message rule library has to be rebuilt by hand. Vendors say "easy migration." Operators who have done it twice know better.

Pick once, commit for 12 months, then reassess. The cost of switching often outweighs the feature gap you thought you were fixing.

You are not buying software. You are buying the quiet that comes from knowing the 11 p.m. checkout question got answered without you.

What Is iGMS vs Hospitable vs Smartbnb

It is a comparison query that should really be iGMS vs Hospitable, because Smartbnb became Hospitable in 2021. The two real products are aimed at small hosts running 1 to 10 listings. Both connect to Airbnb's official API. Both automate messaging, calendar sync, and team tasks. iGMS is cheaper. Hospitable is faster to set up.

The query exists because Smartbnb-era reviews still rank in search results. Hosts read those reviews, see the old name, and assume there are three live products. There are two. Use the most recent comparisons you can find, and confirm pricing on each vendor's site directly. Airbnb's Help Center lists the current API-certified partners if you want to verify.

The Underlying Tradeoff

Cheaper and more manual setup, or pricier and more turnkey. That is the tradeoff in one line. Pick based on whether your scarce resource is dollars or hours.

How to Choose Between iGMS and Hospitable

Run a structured 14-day test. Do not just read reviews and pick.

Use current platform documentation as a guardrail. Start with Airbnb Help, Airbnb host resources, AirROI market tools, Airbnb Help before you make a pricing, legal, or operating decision.

Price is not the whole problem.

Stage decides the right move.

Run the same review on one listing before you change the whole business. Pull the next 30 days of availability. Count the gaps, weak weekdays, and blocked weekends. Then compare those dates against your photos, rules, reviews, and price. Change one constraint at a time. Give the market seven days to answer before you change the next one.

A good article, course, or coach should make the next action obvious. The output should be a spreadsheet, checklist, message template, pricing rule, or market scorecard you can use today. If the advice stays general, it will not help the listing. If the advice creates one measurable action, you can test it. That is the difference between content that sounds smart and work that changes bookings.
