Platforms

Guesty announced on 17 September 2026 that it had completed the acquisition of Smily, formerly BookingSync, a property management system (PMS) and channel manager widely used in France. The price was not disclosed. Smily's five founders and some of its shareholders are reinvesting part of the sale proceeds in Guesty's capital.

Some figures provided by Guesty: Smily has processed more than €3.3 billion in bookings for 13 million guests (figures as at 31 August 2026) and has held the highest tier of Booking.com's connectivity partner programme for eight years. Guesty also notes that France is reportedly the second-largest short-term rental market in the world, with more than one million active listings.

Tools

The two teams are to pool their product, engineering and support resources around a single platform designed for the French market. Guesty is also announcing that its artificial intelligence features, including its Agent Hub, will be rolled out to Smily customers.

What the press release doesn't say: nothing on pricing, contracts or the migration timeline. For a property manager using Smily, the Smily and Guesty listings should therefore be read side by side, without assuming anything.

If you use Smily or are torn between the two, useful questions to ask both teams:

• Are pricing and contract terms changing, and from what date?
• Will the two products merge, and what happens to the current interface?
• Will support remain in French, with the same contact person?
• Will current integrations (locks, cleaning, trust accounting) be maintained?

To compare with other solutions in the directory: Superhote, RentalReady, Hostaway and Avantio.

Affiliation and partnerships

No partnership or affiliate programme linked to this acquisition has been announced to date. Smily's Booking.com partner status is mentioned in the press release, but it is not yet known what becomes of it within the Guesty group.

Key takeaways

• The acquisition was completed on 17 September 2026, price not disclosed.
• Guesty's and Smily's product, engineering and support teams are to be combined around a single platform for France, with Guesty's AI (Agent Hub).
• Nothing has been announced on pricing, contracts or the migration timeline: these are the questions to ask both teams if you use Smily.
