Look for opportunities to teach your customers how to help themselves.
Here’s an example from Quickbooks online. I ask for help on online banking and it gives me a link. But it also tells me how to find it myself next time.
(Remember: It needs to be polite and subtle, because you don’t want to turn away someone asking for help.)
Over time, you get more self-sufficient customers who are happier (and you’re spending less time and money on support). A big win.
