Should I charge a deposit?
Short answer
Yes. On anything material-heavy or scheduled out more than two weeks. 25 to 50 percent, non-refundable inside a window.
Why
A deposit separates buyers from window-shoppers. It covers your material outlay if they bail. It tells the customer this is a commitment, not a maybe.
How to phrase
'We collect a 30 percent deposit to schedule and order materials. Final balance is due at completion.' Said in the quote, not at the last minute. Nobody flinches when it's normal.
