Booking
Online, by phone, or entered by staff — all three land in one record.
Today
Customers call during a job, get voicemail, call the next guy
Two crews on the same slot because two people wrote it down
No-shows cost you the window and the fuel
After
Books itself at 11pm — web form or a phone agent that answers
One calendar, real availability, no double-booking
Deposit taken at booking; no-shows drop on their own
