A booking lands from Booking.com. You glance at the commission line and do the quick maths. A $900 stay, 15 percent gone, $135. Annoying, but the room is full and the money is real. You move on.
That number is not wrong. The framing around it is.
The $135 is not the cost of the booking. It is the first instalment on the cost of the guest.
The maths every operator does
The standard way to think about an OTA booking is per night. Commission is a line item on this stay. You weigh it against an empty room, decide a filled room at 85 percent beats an empty one at 100 percent, and book it. On a single transaction, that logic holds.
The problem is that a guest is not a single transaction.
The maths that actually matters
A guest who liked your property comes back. When they do, they return by the path of least resistance. That path is the one with their card already saved, their details already entered, the app already on their phone, the account that emails them "prices have dropped for your next trip". For a guest whose first stay came through Booking.com, that path is Booking.com.
So you pay the commission again. And on the stay after that, again. The booking you thought was a one-off 15 percent is a subscription, and you are the one subscribed.
Picture a guest who stays with you four times over a few years. Four stays at $900 is $3,600 of revenue. Booked direct, your cost to acquire the second, third and fourth stays is close to nothing, you already won them. Booked through the OTA every time, that same guest costs you $540 in commission across the relationship. Same guest. Same loyalty. Four times the tax, because the first booking set the channel and nobody changed it.
The figures are illustrative. The mechanism is not.
The villain is not the commission rate
This is the part most operators miss. The damage is not the 15 to 22 percent. The damage is the channel stickiness that nobody priced in.
The guest is not loyal to Booking.com. They are not choosing it on principle. They are defaulting to it because it is the easy option and because no one gave them a reason or a prompt to do anything else. Loyalty to the OTA is just friction working in the OTA’s favour. The OTA understood that years ago. It is why they capture the guest’s email behind a masked forwarder, why they remarket your guest back to themselves, why the app sends the "your trip to the coast" nudge before you have even thought about next season.
You can win that default back. But not by accident, and not after the fact.
You flip the guest on the first stay, or you do not flip them
The window to convert an OTA guest into a direct guest is while they are standing in front of you. The confirmation email. The check-in. The welcome note in the room. The conversation at the desk. The checkout. Those are the moments you collect a real email address (not the masked one), and those are the moments you make the next booking feel obvious.
The capture is half of it. The other half is making direct genuinely better the next time: your best rate, with no surprise, plus one thing the OTA cannot give, a free late checkout, a bottle on arrival, a no-fee change of dates. Then a light follow-up before their usual season so the next trip starts on your website, not in the app.
None of this is complicated. It is one more thing for an operator who is already running a property to set up and keep running, which is exactly why it usually does not happen. The OTA is counting on that.
What this is worth
Run the maths on your own guest base. Take your repeat guests, the ones you recognise, the ones who book the same week every year. Count how many of them still come through an OTA. Every one of those is a relationship you own in every way except the booking, and you are paying a commission for the privilege of a guest who was always coming back.
A direct-booking programme is built to close that gap: capture the guest, give them a reason, and move the next booking onto your own channel. You can run the capture-and-flip yourself with the touchpoints you already have, or it is one of the things we run inside Boost Direct. Either way, the move is the same. Stop paying the lifetime tax on guests you have already earned.
The commission line on this month’s statement is the smallest number in the story. The number that matters is the one you never see: every future stay from every guest the OTA quietly kept.
