Brief history of Smily

BookingSync, the company behind Smily, is a French startup. When we created the BookingSync product, our vacation rental management platform, the goal was to make the lives of vacation rental owners, managers, and agencies much easier. We strove to help them save time and book more so they could spend more time with the ones they love. As we added many powerful features, our platform became more oriented to managers and agencies.

However, we did not abandon the vacation rental owners. We worked hard to rethink our platform so that all the technology we added to BookingSync would create a revolution for vacation rental owners as well.We wanted to give the power back to property managers – power they could use to leverage the reach and features of the biggest booking channels, while growing their customer base and the number of direct bookings on their own terms. That’s how Smily was created.

Whether it’s advertising your property through thousands of websites, managing your booking, accepting a payment, communicating with your guests, or issuing a contract, Smily can handle it. Dedicated to simplicity and ease of use, we have developed an intuitive software that is a friend to owners and small managers alike, throughout every step of vacation rental management.

Smily disrupted the scene with fully delegated distribution of your property to our channel partners. You can maintain a centralized listing with details, rates, and a calendar that automatically updates websites and supports portals like Airbnb,, HomeAway, and VRBO, among others. At heart, we provide a product that is simple, reliable, fast, and fun.
