Steps

  1. Open Front Desk → In-house and open the guest's stay.

  2. In Overview → Manage stay, expand Extend stay.

  3. Choose Additional nights and review New checkout. Choose Extend stay once the date is correct.

  4. Wait for the updated stay and review the new check-out, additional charge and balance in Billing. Resolve an availability or pricing error before trying a different extension.

Alternatively, from Front Desk → Bookings → Edit reservation → Add nights, enter New check-out and choose Extend stay. Save or reset unsaved guest edits before extending. For shortlets, use the shortlet workspace for stay changes; the shared reservation editor supports guest details only.
