Script 01 · Offering a free quote alongside a charged diagnostic visit
Hi [Client name], happy to come take a look and quote the job for free. If what you actually need is for me to find the cause of the problem before you decide anything, that is a paid diagnostic visit — [Amount], credited against the work if you go ahead. Let me know which one you are after.
Why it works Naming both options up front lets the caller pick the right one. You do not have to guess which visit they want.
