For properties tired of reconciling three systems

One Inventory.Every Channel.

Most channel managers sit between your PMS and the OTAs, syncing two systems that disagree. Ours does not sync with your front desk — it is your front desk. Same rooms, same rates, same availability, whether the booking came from Booking.com, your own site, or a walk-in at the counter. A room sold anywhere closes everywhere, because there is only one place it was ever counted.

Why Sync Is the Wrong Idea

The standard hotel stack is three products from three vendors: a PMS holding the room rack, a booking engine on your website, and a channel manager wired to the OTAs. Each one holds its own copy of what is available, and the whole business rests on those copies agreeing. They do not always agree.

  • Every sync has a delay. In that window a room can be sold twice — once on Booking.com and once at your desk.
  • So you hold a buffer room back from the OTAs to absorb the gap, which means deliberately not selling inventory you have.
  • Rates get updated in one place and not another, and a guest arrives holding a price you stopped offering in March.
  • Somebody spends the first hour of every morning reconciling three screens instead of running the hotel.
  • When it does break, nobody owns it — the PMS vendor blames the channel manager, and the channel manager blames the PMS.
  • Three subscriptions, three support queues, three contracts, and an integration between each pair to keep alive.

Not Synced. Shared.

FullGuest holds one set of rooms, rates and availability. The booking engine reads it. The front desk reads it. The channel manager pushes it to every OTA and writes their reservations straight back into it. There is no second copy to fall out of step, because there is no second copy.

  • Rooms, rates and availability kept in step across Booking.com, Airbnb, Expedia, Agoda and 60+ channels.
  • OTA reservations land directly in your calendar as real bookings, on the same rack your desk works from.
  • A booking on any channel — OTA, your own site, or the front desk — closes availability everywhere.
  • No buffer room held back "just in case", because there is no sync gap to absorb.
  • Rate changes reach every channel from the same calendar your team already edits.
  • One vendor, one support queue, one contract — and nobody to blame but us.

What It Actually Does

60+ channels, one rack

Booking.com, Airbnb, Expedia, Agoda and the rest connect to the same inventory your front desk sells from — not to a copy of it.

  • Availability pushed to every connected channel as it changes
  • OTA reservations pulled in as real bookings with guest details
  • Per-channel control over which room types you expose
  • Cancellations and modifications flow back the same way

Double bookings, structurally

This is the difference between a promise and a property of the system. Two channels cannot sell the same room because they are both reading and writing the same count.

  • Sold on any channel, closed on all of them
  • No buffer inventory withheld to cover a sync delay
  • Front-desk walk-ins reduce OTA availability the moment they are taken
  • Stop-sell and closed dates hold everywhere at once

Rates from one calendar

Your rate plans and rate calendar are the source. Change a night, and every channel gets the new price — with The Rainmaker able to set those prices for you if you let it.

  • Rate plans per room type, edited by date on one calendar
  • The Rainmaker prices each night from booking pace, comp set and events
  • Guardrails you set — advisory by default, autonomous only when you allow it
  • Stop-sell respected; nothing quietly overrides a closed date

And the rest of the hotel

A standalone channel manager ends at the reservation. Here the same system runs the stay it starts — which is the whole reason the inventory can be shared in the first place.

  • The OTA guest checks in, orders room service and runs a tab on one folio
  • Web check-in with ID and signature before they reach the desk
  • Housekeeping, restaurant, stock and staff on the same login
  • One invoice at checkout, whatever channel they arrived through

Company Brain

Your hotel on autopilot — you stay in control

It reads every folio, booking and shift — surfacing the empty-room nights you could have sold, the services never posted to the bill, and where labour outran the day’s occupancy.

It works the back office the way a seasoned operator would — every day, across every number. It drafts the fix and does the busywork; nothing touches your menu, prices or bookings until you approve. It proposes. You dispose.

Watches
Every order, shift, folio and store — 24/7, so nothing slips past.
Flags
Where money is leaking and what to fix — in plain language, with the numbers.
Acts
Drafts the action and handles the busywork — you approve with one tap.

The Rainmaker

Your AI revenue manager — it knows what tonight is worth, on every channel

Built on Rate Intelligence and the new Channel Manager: it reads your booking pace, comp set and event calendar, then prices every night across your direct site and every OTA — within guardrails you set, acting only as far as it has earned your trust.

One login, one bill

Replaces the stack you're paying for now

Most hotels run on six or more separate subscriptions that barely talk to each other. FullGuest does the lot — so you cut cost, cut logins, and finally get every number in one place.

Three Systems vs One

PMS + booking engine + channel manager
  • Three copies of your availability, kept in step by sync
  • A sync window in which the same room can sell twice
  • A buffer room held back from OTAs to cover the gap
  • Rates updated in one place, stale in another
  • Three vendors who each blame the other two
  • The channel manager ends at the reservation — it knows nothing about the stay
FULLGUEST
FullGuest
  • One inventory that the desk, the booking engine and every OTA share
  • Sold anywhere, closed everywhere — no window to exploit
  • Sell every room you have, because nothing is held in reserve for sync
  • One rate calendar feeding every channel, priced by Rainmaker if you want
  • One vendor, one support queue, one contract
  • The same system runs the stay: folio, room service, housekeeping, checkout

What Hoteliers Ask

Which channels do you connect to?+

Booking.com, Airbnb, Expedia, Agoda and 60+ channels in total. Availability and rates push out as they change, and OTA reservations come back into your FullGuest calendar as real bookings with the guest details attached — on the same rack your front desk works from.

How is this different from SiteMinder or a channel manager bolted onto my PMS?+

A conventional channel manager sits between your PMS and the OTAs and keeps two systems in agreement. Ours is not between anything — the channel manager, the booking engine and the front desk all read and write the same inventory. That removes the sync window rather than shortening it, which is why you do not need to hold a buffer room back.

Do I still need a PMS?+

No. FullGuest is the PMS — rooms, reservations, folios, housekeeping and rate plans — with the booking engine and channel manager built into it, alongside your restaurant, stock and staff. That is what makes one shared inventory possible; you cannot get this property from three separate products however well they integrate.

Can it really prevent double bookings?+

The failure mode it removes is the sync gap: two systems holding separate counts that briefly disagree. Here every channel reads and writes one count, so a room sold on Booking.com is gone from your own site and your desk immediately — and a walk-in taken at the counter is gone from the OTAs just as fast.

What does it cost?+

The channel manager is priced per property as an add-on to any plan, and it includes The Rainmaker. Note what is not in the price: we take no commission on direct bookings through the booking engine, so shifting volume onto your own site does not cost you more.

Does it set my rates as well?+

It can. The Rainmaker reads your booking pace, comp set and event calendar and prices each night across your direct site and every connected channel, inside guardrails you set. It is advisory by default — it tells you what it would do until you decide to let it act.

How long does onboarding take?+

Room types, rate plans and channel connections are the work, and it is days rather than weeks for most properties. We do the setup with you, and we map your existing OTA listings rather than asking you to rebuild them.

Stop reconciling three screens every morning

See the whole path on a live property — a room sold on one channel closing on the others, then the guest arriving, ordering and checking out on the same folio. That is the part three separate products cannot show you.
