For a host with three listings, the channel manager I would buy is Smoobu at EUR 53 a month on monthly billing, plus 0.9% of booking value. BnBGenius is not among them and never will be: we are not a channel manager and we do not synchronise calendars. The runner-up is Beds24 at EUR 24.00 a month for the same three units on two channels: less than half the bill, and the reason to think twice is that the figure is assembled from rooms, room types and channel links you map yourself, so it moves when the map does.
I am Baris Ergin, I work on the product side at BnBGenius, and I should say the awkward part in the same breath as the recommendation: BnBGenius is not a channel manager. We do not sync calendars, rates or availability between Airbnb and VRBO, and we do not do direct bookings. Everything above is a recommendation to buy something we do not sell.
Every price on this page was read in a rendered browser page from a connection inside the United States, not pulled from the page source. That step is not decoration. Two of the five tell you in their own words that the figure on screen is a conversion rather than the amount they will charge, and one of them preselects the currency from the country you are reading in.
Cheapest first, at three listings on two platforms, billed monthly: Beds24 EUR 24.00, Smoobu EUR 53 plus 0.9% of booking value, iGMS $69.99, OwnerRez $70, Lodgify $106. Two of those are quoted in euros and three in dollars, so the ordering is not a straight ranking — it is five bills that arrive in two currencies.
I put Smoobu first for a three-listing host because its number is the one that needs the least from the host to stay true. Set the unit counter to three and the page prints EUR 53; there is nothing else to configure before that figure is real. Beds24 is cheaper and the arithmetic is visible rather than hidden, which I like, but it asks you to know how many room types you sell and how many channel links that produces before the calculator means anything.
| Channel manager | Three listings, monthly | How the figure is built | Billed in | What the figure does not cover |
|---|---|---|---|---|
| Beds24 | EUR 24.00 | EUR 12.90 base account, EUR 2.60 a room, EUR 0.55 a channel link — three rooms, three room types, two channels | Quoted in euros; payable in USD, AUD, CAD, EUR, GBP or NZD | Change the room-type or channel map and the total changes with it |
| Smoobu Professional Flex | EUR 53 plus 0.9% | EUR 29 for the first unit, EUR 12 for each unit after it | Euros. Its own line: subscriptions are billed in EUR, and GBP or USD displays are estimates | The 0.9% booking commission, which is not in the subscription. Professional Prepaid drops it at EUR 59 |
| iGMS PRO | $69.99 | $23.33 a property at three; the per-property rate falls as the count rises | US dollars | Rooms let inside a house you also rent whole are counted as separate properties |
| OwnerRez | $70 | A sliding per-property scale: $40 at one property, $55 at two, $70 at three | US dollars | Owner statements, QuickBooks, hosted sites, the WordPress plugin, SMS and its AI assistant are priced as premium extras. We sell none of those either — no owner accounting, no SMS — and we are not competing for this row |
| Lodgify Professional | $106 | The cheapest plan that a three-property account can actually buy | Shown in dollars to a US visitor, with a EUR and GBP switcher; its own FAQ says the amount due follows the exchange rate at payment time | Basic stops at one rental and Starter stops at two, so neither is on the menu at three |
Say it once more, next to the names: we are not one of those five. BnBGenius does not distribute availability, does not hold your rates, does not talk to a second platform's calendar, does not produce an owner statement and does not send SMS. What is left after a channel manager is installed — the guest asking at 01:40 whether the door code still works, the cleaner who has not been told, the review nobody requested — is the part we work on. The scope lines are set out one product at a time in Smoobu against BnBGenius, Beds24 against BnBGenius, iGMS against BnBGenius, Lodgify against BnBGenius and OwnerRez against BnBGenius.
It closes the gap between a booking landing on one platform and that night disappearing from the others. The booking is instant. The removal is not. Everything a channel manager sells lives in the seconds or hours between those two events.
Take an assumed $250 night, a rate I use for every calculation on this page so the arithmetic stays reproducible. A guest books Friday on VRBO at 19:04. The same Friday is still purchasable on Airbnb until something removes it. If that something is an iCal import, Airbnb's own calendar help says your Airbnb calendar updates every three hours — so the next refresh may not be due until 21:00. An Airbnb guest who books at 20:10 has bought a room that was sold 66 minutes earlier, and no software was broken while it happened.
The bill for that is not $250. It is the $250 night, plus whichever guest gets cancelled, plus the refund, plus what the platform does to a host who cancels. I hold the loss at one $250 night throughout this page because it is the only part I can state without inventing the rest.
An API channel connection and an iCal link are not the same product. iCal moves blocked dates on a timer. An API connection can also move rates, minimum stays, fees and reservation changes, depending on the vendor and the channel. When a page says "sync" I would ask which of those five things actually crosses, because the word covers all of them and vendors are not obliged to be specific. The mechanics for the two platforms most small hosts care about are in how to sync Airbnb and VRBO calendars and what an Airbnb and VRBO channel manager handles.
Answering guests at 11pm is the part software should do.
Start free — first 500 messagesOr book a demo callIf both listings are on one platform, no. There is no second calendar to update and no gap to close. The threshold is the second platform, not the second listing, and most pages selling channel managers do not put it that plainly because the honest answer costs them the sale.
Put those two homes on VRBO as well and the count changes shape: two homes across two platforms is four live calendars, and any reservation on any one of them has to close a date on exactly one other. That is when the subscription starts arguing for itself, and it is worth testing that argument with numbers rather than nerves.
Using the assumed $250 night and an assumed monthly chance that late syncing produces one conflicting night:
| Assumed monthly chance of one conflicting night | Expected exposure at $250 | Against a $69.99 three-listing subscription |
|---|---|---|
| 1% | $2.50 | The subscription costs 28 times the exposure |
| 10% | $25 | Still roughly $45 a month more than the risk it removes |
| 20% | $50 | Closing, but the subscription is still ahead by $19.99 |
| 28% | $69.99 | Break-even: $69.99 divided by $250 |
Read that honestly and most two-listing hosts do not clear the bar on collision cost alone. They buy for the other things a manager brings, which is a legitimate reason — it is just a different purchase from the one the sales page describes.
The free route is a two-way iCal link: export each platform's calendar, import it into the other. The failure mode is the timer. A three-hour refresh cycle means a night can stay purchasable for up to three hours after it is gone, and busy Saturdays are exactly when both platforms are selling. One weekend of that at $250 a night is the entire argument.
There is also a middle option worth knowing about. iGMS publishes a pay-per-night plan at $1 a booked night with a floor of $20 per property a month, so a three-listing host with a quiet month pays the $60 floor rather than $69.99, and a busy month bills by nights sold. If you are still deciding whether this whole software category applies to you, whether a small host needs an Airbnb PMS at all is the prior question.
For a guest house selling rooms rather than whole homes, I would start with Beds24, because it is the only one of the five whose price is built from rooms in the first place. A ten-room B&B on two channels comes to EUR 49.90 a month if each room is its own room type, and EUR 40.00 if the ten rooms are sold as one room type. Same building, same channels, EUR 9.90 apart, and the whole difference is how the rooms are modelled — because the channel links are charged per room type, not per room.
That is the question to put to every vendor before comparing anything: what does your account call a unit? iGMS answers it on its own pricing page, and the answer matters for an innkeeper: if you let the whole house and also let the rooms, those are counted as separate properties. Ten rooms in one building is not one property in that model. Smoobu counts units, so ten rooms is ten units, which is EUR 137 a month on monthly billing. OwnerRez counts properties on its sliding scale, $127 at ten. Lodgify's cheapest plan that serves ten properties is Professional at $203.
Distribution is the second thing that is different. A small B&B usually takes more from Booking.com than from Airbnb, because guests searching a town for one room on one date land there first — and BnBGenius does not support Booking.com, so on the channel that matters most to an innkeeper we are not in the room at all. We answer guest messages on Airbnb and VRBO and nowhere else. For the calendar side of that channel there is syncing Airbnb and Booking.com, and the wider question of which marketplaces are worth a listing is in other apps like Airbnb.
The third difference is the one no software sees. A B&B takes walk-ins and phone bookings, and a channel manager can only distribute a reservation somebody entered. Try the arithmetic on one Saturday: ten rooms, two sold by telephone, one walk-in at $180 paid at the desk. Seven rooms should be sellable online. If only the walk-in was keyed in, the channels are still offering nine, and the first two online bookings that arrive are selling rooms that already have people in them. Nothing in the software failed. The front desk did not tell it.
So for a ten-room house I would rank it: Beds24 at EUR 40.00 to EUR 49.90 depending on room types, OwnerRez at $127, Smoobu at EUR 137, iGMS at $174 on PRO, Lodgify at $203. And I would spend the first week not on software at all, but on the rule that every phone booking is entered before the guest hangs up.
Every figure below is the monthly-billing price on the vendor's own page, read from a United States connection. Annual and multi-year terms are cheaper wherever a vendor offers one, and none of them are in the table, because committing to a year is a different decision from paying a monthly bill.
| Vendor and plan | One | Three | Ten | Basis and currency | Ceiling or floor |
|---|---|---|---|---|---|
| Beds24 | EUR 16.60 | EUR 24.00 | EUR 49.90 | Base account plus rooms plus channel links, quoted in euros | A handling fee applies if you top the account up by less than EUR 50 |
| Smoobu Professional Flex | EUR 29 | EUR 53 | EUR 137 | Per unit, billed in euros, plus 0.9% of booking value | Above 20 properties it stops being a self-service price and becomes a quote |
| Smoobu Professional Prepaid | EUR 35 | EUR 59 | EUR 143 | Per unit, billed in euros, no booking commission | Same |
| iGMS PRO | $48.00 | $69.99 | $174.00 | Per property in US dollars: $48.00, $23.33 and $17.40 a property at the three counts | Their published table runs from 1 to 20 properties; past that it prints nothing |
| iGMS FLEX | $20 floor | $60 floor | $200 floor | $1 a booked night in US dollars, with a $20 per-property monthly floor | Below 20 booked nights the floor decides the bill, not the nights |
| OwnerRez | $40 | $70 | $127 | Sliding per-property scale in US dollars | Premium features are added on top of every figure here |
| Lodgify Basic | $18 | Not available | Not available | US dollars to a US visitor | One rental. The plan renders a dash at two |
| Lodgify Starter | $33 | Not available | Not available | US dollars to a US visitor | Two rentals. $47 at two, then nothing |
| Lodgify Professional | $53 | $106 | $203 | US dollars to a US visitor | The property field accepts up to 100 |
Two rows in that table are the reason it exists. Lodgify Basic at $18 and Starter at $33 are the numbers a host remembers from a comparison article, and multiplying either of them by three produces a plan that cannot be bought: Basic is capped at one rental, Starter at two. At three properties the cheapest Lodgify on offer is $106, which is not $54 and not $99 — it is the first price on the menu.
The currencies are the second trap, and they are not interchangeable. Smoobu states it outright: subscriptions are billed in euros, and prices shown in pounds or dollars are estimates for reference that move with the exchange rate. So a dollar figure for Smoobu is not a price at all — it is that vendor's own conversion of one. Beds24 quotes euros and lets you pay in six currencies. Lodgify shows dollars to a US visitor behind a switcher and says the amount due follows the exchange rate at the moment of payment. iGMS and OwnerRez print US dollars and charge US dollars.
The third thing the table does not show is the commission. Smoobu's Flex plan carries 0.9% of booking value. On $6,000 of bookings in a month that is $54 on top of the subscription; on $12,000 it is $108. A host with a strong summer pays more for the same software, which is the whole difference between a subscription and a cut. Prepaid removes the commission for EUR 6 a month more at three units, and the crossover is around EUR 667 of monthly booking value.
Whatever you land on, budget it as one category among several. Turnovers, pricing, analytics and the tax return are four separate bills, set out in Airbnb cleaning apps, Airbnb pricing tools, Airbnb analytics tools and Airbnb accounting and tax software.
Response speed and calendar hygiene, handled for you.
Start free — first 500 messagesOr book a demo callIt moves availability, and depending on the connection, rates and reservation data. That is the whole job. Buying one does not buy the four jobs that sit next to it, and the $250 Friday makes that visible: the night can be blocked correctly on both platforms while the guest's question goes unanswered, the cleaner is never dispatched, the rate stays where the host set it on a weekend the town is charging more, and the owner gets no statement at the end of the month.
| Job | Category that owns it | Where BnBGenius sits |
|---|---|---|
| Move availability and rates between platforms | Channel manager | Not us. We do not sync calendars or rates |
| Decide the nightly price | Pricing or revenue tool | Not us. We do not set or suggest rates |
| Answer a guest message at 01:40 | Guest messaging | Us, on Airbnb and VRBO, around the clock |
| Answer the phone when a guest calls | Voice agent | Us, through the optional Voice Concierge |
| Ask for the review and post the host's | Review tooling | Us |
| Open the cleaning and repair task after checkout | Operations software | Us |
| Produce an owner statement | Owner accounting or a full PMS | Not us |
| Run a direct booking website | Booking engine | Not us |
Our side of that table is $10 a month per unit on Pro, where a unit is one rentable home and the same home on Airbnb and VRBO counts once. The first 500 messages are free with every feature on and no card. Voice Concierge adds $7 a month per unit, includes 20 resolved calls a month and charges $0.35 per resolved call after that. It installs as a Chrome extension in about five minutes: it reads your own dashboard in your own browser, with no PMS required, no API keys and no login handed to anybody.
Notice what that price does not do: it does not move when your revenue does. Three units cost $30 a month whether the quarter was strong or dead, which is the opposite arrangement from 0.9% of booking value, and a long way from a manager taking a percentage of every night. It is also a much smaller promise. We do not do SMS, WhatsApp, Facebook Messenger, Booking.com or Expedia, and we do not do calendar sync, direct bookings, pricing or owner accounting. I would not buy BnBGenius to stop a double booking, because it cannot: it does not touch the calendar the second guest is buying from.
The pieces we do own are broken out in Airbnb automated messages, review management tools, vacation rental task software, AI voice concierge tools and AI property management.
Connect before you disconnect, block by hand while both systems are live, and verify one date in both directions before you trust anything. The expensive mistake is not a failed connection — a failed connection is obvious. It is a connection that looks fine on the dashboard while one calendar quietly keeps selling.
Ines runs three listings in Asheville, all on Airbnb, and is moving them onto a channel manager before she publishes anywhere else. Here is the arithmetic she does first. Fourteen days of forward inventory across three listings is 42 listing-nights. In the week she picked, 9 of them are booked, which at the assumed $250 rate is $2,250 of committed revenue riding on the migration. Those nine are the dates she checks by hand. The other 33 can be wrong for an hour without costing anybody a room.
Day one is nine checks: for each of the three listings, one booked date, one open date and one manually blocked date. At roughly 40 seconds a check that is about six minutes of work against $2,250 of exposure. She also confirms arrival and departure dates did not shift by one — the classic off-by-one from a check-out date treated as a blocked night — which is 3 listings times 2 boundaries, so 6 more looks.
Day seven is the review that catches the slow failures: every reservation taken in those seven days matched against the source, any date that should have reopened after a cancellation, and any transition block she left behind. A block nobody removed is a night nobody can buy, and it is silent — the calendar simply never sells it.
When she does add VRBO, she publishes one listing, tests one blocked date in both directions, and only then does the other two. And she keeps operations separate from the migration: the cleaner still needs the dates, which is sharing the calendar with a cleaner, a cleaning checklist and maintenance tracking. The platform differences she is about to meet are in Airbnb against VRBO for hosts.
When there is no second platform. Three listings on Airbnb alone have nothing to sync, and neither do ten — the count of listings never creates the problem, the count of platforms does. A host with ten Airbnb-only listings has ten calendars that already block themselves.
After that it is arithmetic. The break-even is the monthly fee divided by the cost of one conflicting night, and it answers a question the host can actually judge: how likely is a collision in a given month?
| Configuration | Monthly fee | Break-even monthly collision chance at $250 | What I would do |
|---|---|---|---|
| Three listings, one platform | Not applicable | No cross-platform collision to price | Do not buy for sync. Buy for something else or not at all |
| One listing, two platforms, iGMS FLEX floor | $20 | 8% | Cheap enough that iCal's three-hour window is the only thing to weigh |
| Three listings, two platforms, OwnerRez | $70 | 28% | Worth it if a busy season genuinely produces a near-miss most months |
| Three listings, two platforms, Lodgify Professional | $106 | 42.4% | Buy for the website and the automations, not for collision cost |
I will not run that division on Beds24 or Smoobu, and the reason is the point of this page: dividing a euro subscription by a dollar night produces a number that looks like an answer and is not one. For the euro-billed products, do it with your own nightly rate in euros, or convert the subscription on the day you are actually charged.
What flips the decision is booking velocity, not inventory. One listing selling 26 nights a month on two platforms creates more collision risk than five listings selling six nights each on one. Before shopping, I would write the requirement in a single line — "distribute availability for three listings across two platforms, and one conflicting night costs me $250" — because that sentence contains the unit count, the channel count and the money, and a product either meets it or it does not.
And if the sentence you end up writing is about messages, reviews, calls or cleaning rather than calendars, the answer is not a channel manager at all. That side of the workload is covered in Airbnb automation software, managing several listings remotely, the automation mistakes beginners make and running an Airbnb closer to autopilot. BnBGenius lives on that side of the line, and not on the one that keeps two calendars honest.
