A lot of small businesses carry these answers in their heads, or in a thread from last month that can't be found in a hurry. That's why the typing happens again.
Write the answers once, and put them where you can reach them
This week, jot down the questions you actually get, not the ones you think you ought to be asked. Ten is plenty. For each one, write a short, plain answer in the words you'd use on the phone. Don't dress them up.
Turn the best of those into saved replies, in the inboxes and messaging apps you already use, so the next time the question arrives you can send a considered answer in a moment, and still tweak it if the person needs something particular.
If you have a website, or a page on a booking tool, put the most common answers there as well, and point to that page in your replies. People who like to read ahead will help themselves. People who still message you can have the same wording, quickly.
Keep the list somewhere you can edit it. Hours change. Parking changes. A useful answer from last spring can become a wrong one. A short review of the list every few months, or when something changes, is enough.
You don't need a grand knowledge base. You need a living note, and the habit of sending it rather than rewriting it. If a new question starts to repeat, add it. If an old one dies off, leave it at the bottom or take it off.
Written with you, from your own answers
We'd draft a short set of answers from your own FAQs and past replies, so you can approve them once and reuse them. The wording would be yours, or written with you, not a generic script. We'd put those answers into the places you already work: saved replies, a page, a booking confirmation, according to what fits.
Nothing would be published or sent as a default until you've approved it. When something changes, we'd update the draft and you'd see it before it goes live, if you're having us look after it.
The site, the booking tool, the inbox: those stay in your name, paid for on your card. We charge for the writing and the setup, and for keeping the answers current if you want that to be part of a monthly care arrangement. If we step back, the answers stay in your accounts, ready to use.
You will still get the odd question that isn't on the list, and those are often the interesting ones. The point is that the ordinary ones no longer take a fresh paragraph, every time, in the middle of a busy day.
