If a customer calls and says, 3 cameras are down, do you give them a firm day and time? Tuesday at 1pm?
This is commercial clients, not residential.
We do not give a time, but a day. Setting a time is just a waste as we would wind up rescheduling most calls. 3 cameras down can be as easy as rebooting a switch, resetting a breaker, or as hard as having to troubleshoot a broken wireless link, tone cable, replace devices etc. Wide time frame.
I ask because almost every dispatch/service software I have tried wants us to make firm appointments. We usually can not dispatch to a tech, or email the client the work order unless there is a set time.
