Tickets, labor and parts.
Set up your service menu, take in a customer's gear, then charge for the work and hand it back. Three missions, about 35 minutes.
Add the services, labor time and parts to a ticket, take the payment at the register, and close the ticket when the customer picks up. About 15 minutes.
The four columns on the Service board, what moves a ticket from one to the next, what the customer is told at each step, and who can do what.
Your labor rate, the services you sell, the questions asked at drop-off, and the messages a customer gets. About ten minutes.
Make a service ticket at the counter in five quick screens, then print a copy that stays with the gear. About ten minutes the first time.
