Are you sure I'll get the order?
To whom to entrust the order, customers choose themselves. The decision is influenced by the questionnaire, your offer and the price of the service. Respond to 5-7 orders at once — so there are more chances to get one of them.
If the client disappears?
Clients are ordinary people, and their plans can really change sometimes. We can't influence it. If you see that the client is in doubt, discuss it. Ask for a warning if you need to reschedule or cancel an appointment.
