The short answer
Before hiring a business consultant, ask how they diagnose a business, what experience they have with companies your size, who will personally do the work, how success will be measured in your financial statements, what the engagement costs and includes, what happens if results don't come, and how you can end the engagement. Then call two references who run businesses like yours.
- Questions about method reveal more than questions about credentials.
- Listen for specific answers with numbers, not general promises.
- A good consultant is glad you asked; a weak one gets defensive.
You don't need to ask all twenty-one in one sitting. Most are covered naturally in a good first conversation, and a strong consultant will answer several before you ask. Use the list as a checklist afterward: which did you get clear answers to, and which were dodged?
Questions about their experience
- How many businesses of my size have you worked with? Look for real experience with companies between one and ten million in revenue, where the owner is still deeply involved and management layers are thin.
- Have you worked in my industry, or one with similar economics? Similar economics — labor-heavy, project-based, recurring service — can matter as much as the same industry. See does your consultant need industry experience?
- Can you describe a client whose problem looked like mine, and what changed? You want a specific story with specific numbers, told without breaching anyone's confidentiality.
- What have you done yourself, as an operator? Consultants who have run teams and budgets tend to give more practical advice than those who have only advised.
Questions about their method
- What will you need to see before you recommend anything? The right answer involves your financials and time inside the operation, not just a questionnaire.
- How long does your discovery take, and whose time does it use? Good discovery mostly uses the consultant's time, observing your business as it normally runs.
- How do you decide what to fix first? Look for prioritization by financial impact — every finding priced in dollars per year.
- Do you implement, or do you hand over a plan? This single answer explains most of the price differences between consultants.
- How do you involve my managers and staff? Change built with your team outlasts change imposed on it.
Questions about who does the work
- Who, by name, will be in my business each week? Meet that person before you sign.
- How many clients are you working with at the same time? Too many, and your engagement gets whatever attention is left over.
- Do you bring in specialists, and who pays for them? Accountants, attorneys and software specialists sometimes need to be involved; know how that works up front.
Questions about results
- Which numbers in my financial statements should change, and by roughly how much? A specific answer after discovery is a strong sign.
- How will we measure progress along the way? Look for regular review points against a recorded baseline.
- What happens if the results don't come? Continued work, a fee reduction, a guarantee — or nothing at all? Our article on consulting guarantees explains what a meaningful one contains.
- What will I be able to do without you when this ends? The goal of a good engagement is to leave you independent, not dependent.
Questions about cost and terms
- How is the fee structured, and what exactly does it include? Hourly, project, retainer or performance-linked — and what's billed as extra. See consulting fee structures explained.
- What will I need to spend besides your fee? Software, equipment, training or other advisors the plan might require.
- How much of my time and my managers' time will this take? Plan for it honestly. Our guide to the owner's time commitment gives realistic expectations.
- How do we end the engagement if it isn't working, or when it's done? Reasonable notice periods and a clear wind-down are signs of a confident consultant.
- How do you protect my confidential information? You'll be sharing financials and personnel issues. Expect a clear, practiced answer.
Questions to ask their references
Asking the consultant is half the job. The other half is asking the people who've hired them. When you call a reference, ask:
- What was the problem when you hired them, and what changed in your numbers?
- What did they do that you couldn't have done yourself?
- How much of your time did it take?
- What frustrated you about working with them?
- Did the changes last after they left?
- Would you hire them again, and for what?
Our full guide to checking a consultant's references explains how to read between the lines of what references say.
Questions to ask yourself first
The conversation goes better when you've answered a few questions of your own before the call. Consultants can only be as useful as the brief they're given, and these answers sharpen it considerably.
- What are my three biggest problems, in order? Not symptoms like "we're always busy," but the underlying issues you suspect: margins, a key manager, cash timing, an owner bottleneck.
- What does each one cost me per year? A rough number is enough. It turns every conversation from opinion into arithmetic.
- What have I already tried, and why didn't it hold? This tells a good consultant whether the gap is knowledge, time, structure or authority.
- What would "fixed" look like twelve months from now? In numbers where possible: margin, owner hours per week, revenue per employee, days to collect.
- How much time can I genuinely give each week? Implementation needs the owner. Be realistic.
- Who else needs to be involved? A business partner, a spouse who co-owns, a key manager. Surprises later cost time.
Owners who arrive with these answers get far more from a first call, and can compare consultants on how well each one engages with the same brief.
How to read the answers
The content of each answer matters, but so does its shape. Good answers tend to be:
- Specific. Numbers, names of steps, examples — not adjectives.
- Honest about limits. A consultant who admits what they don't do is more credible than one who does everything.
- Curious about you. Strong consultants ask as many questions as they answer, because they're already diagnosing.
- Unhurried. No pressure to sign this week, no expiring discounts.
Warning signs in the answers include vagueness about results, reluctance to name who does the work, a fixed program offered before discovery, and defensiveness when you ask about guarantees or exit terms. Our list of business consultant red flags goes further.
How we answer the hardest questions
You can put all twenty-one to us. The short versions: you work directly with Armando Juarez, an ASBC-accredited consultant who has served 300+ businesses; discovery is on site and prices every finding in dollars per year; we implement with your team rather than hand over a plan; results are measured in your own statements; and the engagement carries a 2×1 guarantee — at least two dollars of additional net profit for every dollar invested, on a measurement basis written into the agreement. The full sequence is in how our engagements work.
Frequently asked questions
What is the most important question to ask a business consultant?
"What happens if the results don't come?" It forces the consultant to reveal whether they're confident in their method and willing to share any of the risk — and it tells you how the relationship will work if things go wrong.
Should I send questions in advance?
Yes, it's a good idea for the most important ones. A consultant who prepares thoughtful written answers is showing you how they'll work. It also keeps the first call focused on your business rather than their pitch.
What should a consultant ask me on the first call?
Expect questions about your revenue, margins, team, biggest frustrations, what you've already tried, and what "fixed" would look like. If a consultant asks very little and talks mostly about themselves, that's worth noticing.
How do I prepare for that first conversation?
Have your recent financial statements to hand, write down your top three problems and what each costs you, and know what outcome you want. Our guide to preparing for a first meeting has a full checklist.
How long should a first call with a consultant take?
Thirty to sixty minutes is typical. Long enough to cover your situation and the key questions on this list, short enough that it stays focused. A consultant who needs two hours just to explain their program is telling you where their attention will be.
Is it rude to ask a consultant about their failures?
Not at all. Asking "tell me about an engagement that didn't go well and what you learned" is one of the most revealing questions you can ask. Experienced consultants have honest answers.
