Opening hours. Do you cover my area. Roughly what does it cost. Most enquiries aren't really questions, they're the same handful, arriving at 9pm when nobody's there to answer them.
Personally answering the same thing over and over, often outside working hours, is a poor use of an evening. It compounds too: every slow reply loses a bit of trust, and whoever answers first tends to win the enquiry regardless of who'd have done the better job, so the cost isn't one late reply, it's every late reply, adding up to fewer enquiries converting at all.
Read what's come in against what's actually true about your business, hours, prices, service area, kept accurate by you, and have a reply drafted, ready to check and send.
Imagine every routine enquiry getting a fast, accurate reply without you personally typing it at 9pm, so the questions that actually need a real person get your real attention.
There's an example of this here.
