Smily, formerly BookingSync, is a French vacation rental PMS for professional property managers with multi-property portfolios, primarily across Europe. It provides reservation management, multi-channel OTA distribution, direct booking website tools, owner portals, native payments, and a REST developer API.
The PMS offers a unified reservation calendar with multi-channel sync, property listing configuration with rate plans across channels, and real-time inventory to prevent double bookings. Channel connectivity covers Airbnb, Booking.com, Vrbo, Expedia, HomeToGo, and Holidu with OTA listing mapping. A direct booking website module with CMS supports SEO and AI-assisted listing content optimisation. Smily Payments handles multi-currency collection across European markets. The owner portal provides real-time financial visibility, automated earnings reports, and a Revenue Distribution feature producing transparent payout calculations with normalised line items for OTA fees, commissions, and processing costs. A unified inbox plus Smily AI handles multilingual inquiries. The developer API uses OAuth with read/write scopes and webhooks for booking and inventory events.
Professional vacation rental management companies in France and wider Europe needing API depth and owner-facing financial transparency.
Smily, the French property management system and channel manager founded in 2010, has been acquired by Guesty; the deal has now completed and terms were not disclosed. Smily has processed EUR 3.3 billion in bookings for 13 million travellers and serves French vacation rental hosts and property managers. Smily CEO Sebastien Grosjean said that with the industry and its technology moving as fast as they are, bringing the Smily team and its knowledge of France and Europe to Guesty was the better path. Guesty CEO Amiad Soto pointed to France as one of the fastest-growing short-term rental markets, with over one million active listings and roughly USD 9 billion in annual OTA gross booking value, and said Guesty will bring its AI and Agent Hub tooling to Smily customers.
