Booking engine, channel manager and PMS: what each one is and which your property needs

The three are sold together and get mixed up. But they do different jobs, and if you don't know which is which, you end up paying for one you don't use or missing the one you need.

Three different jobs

The booking engine sells direct: it's the part of your website where guests pick dates, see the price and pay. The channel manager distributes: it sends your rates and availability to Booking, Airbnb and the other platforms, and brings in the bookings they make. The PMS runs the house: bookings, rooms, check-in, payments.

Three systems, three jobs

Why they have to be connected

If each system keeps its own calendar, someone copies by hand what happens in the other. That's where two bookings for the same room and rates that don't match come from. The norm is one inventory that the others read and update.

Many providers sell all three in one package. On the websites of places to stay in El Chaltén that we reviewed you'll find, among others, Todo Alojamiento, Cloudbeds, RoomCloud and Pxsol.

What a small property needs

If you sell only on Booking, you need none of this: the extranet is enough. When you add a second platform, a channel manager saves you from selling the same night twice. And when you want guests to book direct, you need the engine.

A PMS starts to make sense when there are several rooms, people at the front desk and payments to reconcile. For a cabin or two, the channel manager's calendar is often enough.

An engine alone doesn't sell

A booking engine is a till. If nobody reaches your website, it rings up nothing. What brings direct bookings is your site showing up when someone searches for your property or your town on Google, loading fast on a phone and showing what guests want to see before they pay.

That's why, when we build a website for a place to stay, we connect it to the engine it already uses and work on what surrounds it: speed, photos, SEO and Google's free booking links.
