Reservations and invoices

A few switches worth knowing:

  • Block Checkout with Balance: don’t check out a guest who still owes money.
  • Lock Invoice After Checkout and Lock Dates After Checkout: protect finished stays from accidental edits.
  • Auto No-Show on Night Audit: marks unconfirmed reservations as no-show once their arrival date has passed.
  • Guest Self-Modify: adds a link to confirmation emails so guests can view and change their own booking.
  • Hourly Bookings: time-based bookings with check-in and check-out times, for day-use rooms.
  • Default Check-in / Check-out Time: the standard arrival and departure times for your property.
  • Require Room Assignment: every booking must have a specific room. When off, bookings can be left unassigned.
  • Hide Forecast Charges: hides future nights from the invoice.
  • Show Logo / Rate on Registration Card: choose what the printed card shows.

Appearance

Settings → Features → Appearance changes how the calendar looks and what things are called.

  • Calendar Days: how many days the booking calendar shows by default (10–30).
  • Status Colours: Strong, Light or Classic palettes for booking bars, plus Reservation Font Colour, Reservation Borders and Calendar Date Size.
  • Room (Singular / Plural) and Room Type Label: call them Units, Suites, Cabins or Sites throughout the app, which suits apartments and campgrounds.
