Every booking site, kept in step
Rates out, bookings in, and the same rules everywhere.
Rates and availability in sync
Change a rate or close a room once and every connected booking site follows.
- Each connected booking site and its status
- The last update sent to each one
- Alerts when a connection goes quiet
Included with the channel manager
Everything you need to sell on booking sites safely.
Rates and availability in sync
Change a rate or close a room once and every connected booking site is updated. No more logging in to each extranet.
Bookings straight in
Bookings from booking sites arrive in your diary and on the guest record, ready for your front desk and your guest emails.
Restrictions where you need them
Set minimum stays, close to arrival and stop selling on busy dates, and the rules travel to every channel.
Room mapping made simple
Match your room types and rate plans to each booking site once, with clear checks if anything is left unmapped. Add a new room type and you’re reminded to map it before it goes on sale.
Sync health you can see
A log of every update, with alerts when a connection goes quiet or an update fails, so you can fix it before it costs a booking.
Out-of-order rooms handled
Log a maintenance fault and the room comes off sale on every channel until it’s fixed.
Every feature, in detail

Make it yours. Let it do the legwork.
Shape it to how you work, and let it handle the routine for you.

Each channel, your way
Manage each property’s connections and see the sync status of every rate plan, with a retry button.

Retries and stop-sells for you
Failed updates are retried every few minutes, and booking sites are closed automatically when rooms run short.

One room stock
Booking sites and your website sell from the same room stock, shown in one grid.
What it replaces
A separate channel manager subscription and the manual checks that come with it.
Stand-alone channel managers
SiteMinder and RateGain charge their own monthly fee and need their own connection to your hotel system, which is one more thing to break. Here the channel manager is part of the hotel system itself.
Extranet admin
No more logging in to update each booking site by hand when a rate changes or a room goes out of order. You change it once, in one place, and every channel follows.
Double-booking clean-up
Rooms, rates and bookings live in the same system as your front desk, so availability is always taken from one diary and your team stops apologising for rooms that were sold twice.
YOUR AI TEAM, ON CHANNELS
It spots sync problems before guests do
Switch it on and it works around the clock. Nothing goes out without your approval.
Channel checks
Spots booking sites that stopped syncing, connections that have gone quiet and channel prices that have drifted apart, and tells you which one to fix first.
Resync suggestions
Proposes a resync, a new connection or a fix to a room mapping, ready for you to approve in one click. Nothing changes until you say yes.
Quiet nights flagged
Finds coming nights that are well behind last year and suggests short-stay offers or packages to fill them, with the promotion drafted for you.
Set up by real people, supported by AI. An mDOS Expert Partner connects your booking sites and checks every room mapping with you, and the AI team keeps an eye on sync once you switch it on.
Switch at your own pace
Keep your current channel manager while its contract runs out, then switch over on a quiet date. We bring your future bookings and room mappings across, and agree a tailored switching plan so nothing is double-sold.
Three things no one else brings together
Syncing booking sites keeps you safe. mDOS adds AI agents that spot problems before guests do, and a team that helps you win more direct bookings.

World-leading software
Rates, rooms and restrictions kept in sync with the booking sites you sell on, with their bookings arriving straight in your diary.

Tireless AI agents
AI agents spot sync problems and drifting prices, propose a fix for you to approve, and find quiet nights with a short-stay offer drafted to fill them.

Real experts driving it
An mDOS Expert Partner connects your booking sites and checks every room mapping with you, and partner marketers help you win more bookings direct.
