Required by Bulgarian law

Stop filling ESTI manually

Bulgarian law requires hosts to register every guest with the ESTI portal within 12 hours of check-in. Rentiera collects guest details and generates the ready-to-upload CSV — automatically.

FAQ

Common questions

Do I need this if I'm on Airbnb or Booking.com?

Yes. Bulgarian law requires hosts to register guests with ESTI regardless of the booking platform. Airbnb and Booking.com do not handle ESTI registration for you.

What if I have multiple properties?

Each property gets its own unique guest link. Your subscription automatically adjusts as you add or remove properties — you only pay for what you use.

Is my guests' data safe?

Guest data is stored securely and used only for ESTI compliance purposes. It is never sold or shared with third parties.

Can guests submit in Bulgarian or English?

Yes. The guest registration form is available in both Bulgarian and English, so international visitors can complete it comfortably.
