Small hotels, guesthouses, serviced apartments and resorts often start with one shared booking spreadsheet. The risk shows up when two reservations overlap, statuses drift, or availability has to be checked manually.I built a focused Google Sheets booking-control service for that exact problem:• centralized reservations table• room/unit-level overlap detection• HOLD / CONFIRMED / CHECKED_IN / CHECKED_OUT / CANCELLED statuses• automatic night calculations• conflict flags• simple availability view• handoff notesThe portfolio example uses synthetic data — I’m not presenting it as paid client work.Fixed scope starts at $79 for one property, up to 30 rooms/units:https://contra.com/s/NqPLPBm6-i-will-build-a-google-sheets-booking-control-systemIf your property already runs reservations in Sheets and double-booking/availability checking is the pain, send me the current structure and I’ll tell you whether it fits the fixed scope.
