And most people choose them badly, in a consistent way: they ask what they would like to know, rather than what would change their next action.
The test every question must pass
One rule, and it eliminates most candidates.
Would a different answer change what I do next?
If yes, keep it. If no, cut it — regardless of how reasonable it sounds.
“Where is the work located?” passes decisively for a contractor. Forty minutes outside your radius versus two streets over changes whether you call at all. “How did you hear about us?” usually fails. It is genuinely interesting for marketing, and it will not change a single thing about your callback. Save it for the conversation, where it costs nothing.
Applied honestly, this rule cuts most lists in half, which is the point.
Four questions, not eight
The instinct is to ask more. Resist it, for three reasons.
Callers abandon. A stranger who called to ask about a bathroom will answer four questions. By the seventh they conclude they have reached a system rather than a business, and they hang up. A long interrogation converts worse than a short one, so more questions can genuinely yield less information.
You have to read the result. A twelve-field message has to be parsed. A four-field message is absorbed at a glance, which is what you need when you check your phone between tasks.
Marginal value collapses fast. Questions one through four do the heavy lifting. Five and six are occasionally useful. Seven onward almost never changes anything.
The floor and the ceiling
Below three questions you generally do not have enough to prepare a callback. Above six you are trading completion rate for detail you will not use. Four or five is where nearly every business lands.
The two you almost always need
Name
Not for records. For the first three words of your callback. “Ms. Alvarez?” is a different opening than “Hi, I had a missed call from this number.”
Best callback number
Ask it explicitly even though caller ID exists. People call from a shop line, a spouse’s phone, a car system, a blocked number. The number they want you to use is often not the number they dialled from, and this is the field whose absence wastes the most of your time.
Choosing the middle two
Everything else follows from what you personally need in order to decide, and there are three broad shapes.
The qualifying question
The one that determines whether this is your job at all. Location for anyone with a service radius. Residential or commercial where rates and licensing differ. New or existing customer. It should be answerable in a word or two.
The substance question
The one that tells you what the conversation is actually about, and the one whose phrasing matters most.
“How can we help you?” yields “I need a quote.” Ask for the concrete thing instead: what is the project, what is the system doing, what room and how much of it, which service are you asking about. Concrete prompts produce concrete answers; open prompts produce restatements of the obvious.
The timing question
Consistently under-used and cheap. Whether someone needs it this week or is planning for spring reorders your entire callback list at the cost of one question. It also prevents the awkward discovery, six minutes into a callback, that your book is full past their deadline.
Worked sets
Four each, in asking order.
General contractor
- Your name?
- Best number to reach you?
- What street or town is the work on?
- What are you looking to have done, and when would you want it started?
Plumbing, electrical or HVAC
- Your name?
- Best number?
- What is the service address?
- What is happening with the system right now?
Hair salon or studio
- Your name and best number?
- Have you been in with us before?
- Which service are you asking about?
- When were you hoping to come in?
Interior designer or architect
- Your name?
- Best number?
- Where is the project, and is it a renovation or new construction?
- What is the scope — a room, a floor, a whole house?
Real estate agent
- Your name and best number?
- Are you calling about a specific property, and if so which one?
- Are you looking to buy, sell, or both?
- What is your timeline?
Cabinet shop or fabricator
- Your name and best number?
- Are you calling as a homeowner, or for a builder or dealer?
- Is this a new enquiry or a job already in progress — and if in progress, the job name or address?
- What material and roughly what scope?
Phrasing that works out loud
These are spoken, not read, which changes the rules.
One thing per question. “What is the project and where is it and when do you need it?” gets you an answer to whichever part the caller remembers last.
Short sentences. A caller half-listening while doing something else will follow eight words and lose sixteen.
No jargon. A homeowner does not know what a scope of work is, whether they have a service panel, or what your minimum is. Ask in the words your callers use.
Easiest first. Name and number are effortless and build momentum. Leading with your hardest question is how you get hang-ups.
What questions should never do
Two hard limits, and they are about honesty rather than capability.
Do not ask anything that implies a commitment you have not made. “What day would you like us to come out?” sounds efficient and is a trap — the caller now believes something is scheduled. Nothing is. AnswerCraft does not book appointments, and your questions should not suggest otherwise.
Do not collect sensitive information. No card numbers, no account numbers, no identity details. A missed-call greeting has no business holding any of that, and asking for it undermines the trust you were trying to build.
Revisit them once
After two weeks, read your messages and ask two things: which field do I look at first, and which field have I never once used? Promote the former, delete the latter.
That is the whole maintenance burden, and it is the difference between the tool working for you and you working for the tool.
