💳 Payment

Duve does not support live folio sync with Smily. The guest sees the rent price and paid amount as they stood at the last sync, not a live balance from the PMS.

What the guest sees comes from two Smily fields: the final price and the paid amount. There is no itemised folio, and charges added in Smily after the last sync are not reflected until the next one.

Restrictions and limitations

Only Booked reservations are imported. Tentative, Locked and Unavailable are skipped, and anything checked out more than 30 days ago is ignored.
Room name, street and street number sync once, on first creation only - they’re explicitly excluded from updates so Duve doesn’t overwrite them.
For Airbnb bookings, Duve picks Smily’s Airbnb proxy email so messages route to the Airbnb inbox.
Guest documents / passport scans are explicitly excluded from push for Smily
Phone numbers. Duve takes the first non-fax phone on the Smily client.
Upsells, Early check-in, late check-out and custom services, are sold in Duve as normal. The charge itself is not posted to the Smily folio, only payments for the stay reach Smily. The upsell is visible in Duve, and in Smily only through the comment Duve writes on the reservation.
