Working with online travel agencies: a hotel’s guide to booking sites

An OTA (online travel agency) is a website that sells a hotel's rooms to travelers under a contract with the hotel, usually for a commission or at a net rate. It is one channel among several, next to tour operators, travel agencies, metasearch and the hotel's own website. For any OTA hotel relationship, the contract, not the website, decides the rules.

A booking site's contract arrives as a few pages of terms and an extranet login. Six months later the argument is about a rate the hotel published on its own website, or a commission invoice nobody reconciled. Both were settled in the pages nobody read. After this article you will be able to read a contract for the four clauses that matter, know what you control in the extranet, and write a role sheet for each site so that every OTA hotel channel has a defined job.

What is an OTA, and how does it differ from a tour operator or a metasearch site?#

An OTA is an online travel agency: a website that lists a hotel's rooms and takes bookings from travelers under a contract with the hotel. A tour operator buys rooms at a net rate and resells them, often inside a package; a metasearch site compares prices and sends the traveler to whoever sells the room.

The OTA sells at a retail price the hotel sets or approves and is paid a commission, or buys at a net rate and marks it up. Which one applies is written in the contract, not in the website's design. The tour operator carries the risk: it commits to a block of rooms, sets the package price and pays the hotel net. The hotel gives up pricing control and gains a commitment.

Metasearch takes no booking. It shows prices from several sellers and links out; the reservation itself happens on the OTA or on the hotel's own site. The guest relationship also differs by door: on an OTA the traveler often returns to the same site for the next trip, so the hotel sees the stay but not the repeat behavior.

A quick test for any site: ask who is the seller on the traveler's receipt. That single answer tells you the business model, the payment path and the invoicing duty.

In Türkiye, travel agencies, including online ones, are regulated. Since 26 July 2024 they must verify a facility's Ministry certificate number and show it in their sales and marketing, which changes what a listing has to contain. A hotel can use all three doors at once; the work is giving each a defined job and keeping one room inventory behind them, a topic covered in hotel distribution terms explained: contracts, rates, channels.

Who collects the payment, and who invoices whom?#

It depends on the model written into the contract. In the agency model the hotel collects from the guest and is invoiced for commission; in the merchant model the site collects from the traveler and pays the hotel a net amount.

In the agency model, the hotel takes payment at the property or through its own payment link, issues the guest's fiscal document, and later receives a commission invoice from the site, usually monthly. In the merchant model, the site is the seller to the traveler. It charges the card, handles refunds and chargebacks, and pays the hotel net, sometimes after the stay.

The trade-off is cash flow against risk. The merchant model pays later but moves collection risk to the site; the agency model pays at check-out but leaves the hotel chasing no-shows and card disputes.

Every sale needs a fiscal document, and which side issues it depends on who sells. E-Fatura and e-Arşiv (electronic invoice) depend on the taxpayer's scope, so confirm the setup with your accountant before the first booking arrives. The guest identity notification (KBS) stays with the facility at check-in, whichever model sold the room. The site does not do it for you.

Reconciliation is the recurring job: match the site's monthly statement to the guest bill line by line, including cancellations, no-shows, refunds and adjustments. Commission errors that nobody claims are simply lost. Currency needs a written rule too: a net rate quoted in euro and settled in lira needs an agreed rule for which day's central-bank rate applies, agreed before the first invoice.

What should a hotel read in an OTA contract before signing?#

Read four things first: the parity clause, the cancellation and no-show rules, the payment terms, and how the contract ends. Everything else can be fixed later; these four decide what the hotel can and cannot do.

Parity comes in two shapes. A wide clause obliges the hotel to give the site its lowest room prices and best availability relative to all other sales channels. A narrow clause lets the hotel offer lower prices and better availability on other online agencies and offline channels, while still stopping it from publishing lower prices on its own website (European Commission monitoring report, 2017 (opens in a new tab)). Treat the clause as a commercial term you negotiate, and take advice on your own case.

Cancellation and no-show rules decide who refunds the guest, who pays the hotel when the guest does not arrive, and what evidence the hotel must supply within how many days. Payment terms say when the commission invoice is issued, in which currency, what it deducts, and how long the hotel has to dispute a line. Term and termination say the notice period, what happens to bookings already made for dates after termination, and whether rates stay live during the notice period.

Then read the hotel's own obligations: how many photos, how fast a rate change must appear, minimum availability, and what happens when the hotel's system is down. Finally, liability: who answers a traveler complaint, a double booking or a data incident, and who pays for the remedy.

What does the hotel actually control on a booking site?#

The hotel controls four things through the extranet: content, rates, restrictions and policies. Availability is the result of those four, not a separate job.

Content is room types, photos, descriptions, facilities, board types and map position. Wrong content produces the wrong guest and the complaint that follows. Rates are rules, not numbers: a rate plan ties a price to occupancy, board and cancellation terms, and it is what the site actually sells.

Restrictions are minimum stay, closed to arrival, and stop sale. These protect a sold-out weekend or a concert week without changing the published price. Policies are the cancellation window, children, pets and payment on arrival. The site displays them and the guest holds the hotel to them, so they must match the contract.

Availability is fed from the hotel's system or a channel manager. The failure mode is a room sold twice, which is why one inventory behind every channel matters. The extranet is a second system with its own login and its own mistakes. Someone must own it by name, or nobody does.

Why do certificate numbers appear on booking site listings?#

Because travel agencies in Türkiye must verify a facility's Ministry certificate number and show it in their sales and marketing, and may not sell or market facilities that have none.

The rule comes from the amendment to the Travel Agencies Regulation published in the Resmî Gazete on 26 July 2024, No. 32613 (opens in a new tab). Agencies check the number against the Ministry of Culture and Tourism's database.

What the hotel should check: its own listing carries the correct certificate number and the exact facility name on the certificate. A wrong number is a listing that can be pulled. Uncertified stock, villas, apartments and rooms without a certificate, cannot be sold through an agency under this rule. A hotel group that also rents uncertified units should not expect a site to carry them.

The number is now a listing asset, like photos and rates. Keep it current when a certificate is renewed or a facility changes name or operator. What the rule does not do: it does not certify quality, and it does not replace the hotel's own reading of the contract. Dates, scope and penalties should be confirmed with your legal adviser; this article describes the duty, not its enforcement.

How should a hotel decide each site's role?#

Judge each site by what the hotel keeps after the sale: net revenue, guest data, repeat potential and payment timing. The number of bookings a site reports says little on its own.

Write one role per site: new source market, shoulder-season fill, last-minute fill, long stay, corporate. A site with no role is a site to close or pause. Compare net, not gross: retail price minus commission minus payment cost minus the cost of a cancellation. Do the arithmetic on your own numbers; no published percentage replaces it.

Guest data decides whether the stay can become a repeat booking through the hotel's own website: what the hotel actually receives, name, contact and consent. Cancellation behavior matters too: a channel that fills rooms and then cancels them costs housekeeping hours and blocks inventory. Track it monthly per site.

Parity discipline is a short weekly check that each site's price matches what the hotel believes it published, and that the hotel's own website is not the most expensive door. The routine is described in rate parity check: a weekly routine for direct and OTA prices. Review the whole plan quarterly: a channel's role changes with the season, the source market and the hotel's own occupancy pattern.

The table below is an illustrative template, not a benchmark. Fill it with your own figures.

Track guest data received and cancellations last quarter alongside it. To shift the mix toward the hotel's own door over time, see how to increase direct bookings on your hotel website.

Where does AI Otel stand on booking sites?#

Built, in pre-production testing: availability and rates flow from the hotel's system to the major OTAs through our Channex integration, which has not gone live.

The direction matters. Rates and availability go out from one inventory; reservations come back into the same system, so the room is not sold twice. No OTA is connected today, and we do not claim one. The hotel operating system behind it holds reservations, rates and restrictions in one place, built and working, ahead of launch.

The question to ask any vendor, including us: which sites, which direction, and what happens to the room when the connection drops.

What to do next#

Take one site's contract and one site's extranet this week and write that site's role sheet: model, contract terms, who owns the extranet, certificate number on the listing, and what the hotel keeps after the sale. The article's parts fit in that order, and the sheet is the document that turns a booking site from a surprise into a channel.
