Take the booking online, get every rider on a signed waiver before they arrive, hold the deposit automatically, and photograph the machine both ways — so the scratch argument is over before it starts.
Four people on two machines is four signatures. Collected on their phone before they turn up, not on a clipboard while the group waits.
ATVs come back scratched, bent and full of sand. Hold a real deposit at booking or at pickup, released when it comes back clean.
Timestamped, per machine, both directions. The single thing that ends a damage dispute in one message instead of three days.
Two-seaters, singles, half-day and full-day, guided or self-drive — each with its own rate and its own deposit.
Machines that work hard need servicing on use, not the calendar. Track hours per unit and see what's due.
“Do you have two ATVs for tomorrow morning?” gets a real answer and a real booking while you're at dinner.
