What owners ask most often

Didn’t find your answer? Write to us.

Do I pay any commission on a direct booking?

No. You pay no commission on bookings made on your website, not to anyone and not to us. A website with a booking system costs from €249, and that includes syncing with booking portals and looking after the website.

How much does a website with SFERIN cost?

From €249. We will give you the exact price for your property along with the website preview, which we prepare for you free of charge first. No percentage of your bookings.

Do I have to leave Booking.com or other portals?

No. You can keep your portals. The calendar on your website syncs with them both ways via iCal: days booked on the portals show up on your website, and a confirmed booking from your website is blocked on the portals. It runs automatically, with a delay that depends on each portal.

Is it only for chalets?

No. SFERIN works for any kind of accommodation: a chalet, cottage, log cabin, apartment or guesthouse, including several units on one website.

How long does it take to launch the website?

The website is usually live within a few days, depending on how quickly you send us the materials: photos, price list, descriptions and access to your domain and portals.

I already have a website. What happens to it?

We move the content over and switch the domain without any downtime, redirecting the old addresses. We can also transfer your booking history, reviews and guest records from the old system.

Who looks after the website after launch?

We do. Security updates, daily backups, new features at no extra charge, and support that replies within one working day.
