To choose a business growth consultant, look for three things: relevant experience with companies like yours, a clear method that starts with diagnosis, and a working style that fits how you run your business. The 10 questions below help you test all three in a single conversation, before you sign anything. This guide from 20xBusiness.com gives you the questions we’d want any owner to ask us, too.
This article is part of our complete guide to business consulting. It assumes you already know you need outside help. If you’re not sure yet, start with our list of signs it’s time to hire a business consultant.
Before You Start: Know What You’re Hiring For
You can’t judge a consultant’s answers until you know your own question. Before your first call, write one sentence that describes the problem and the number it affects. For example: “Our average job size has dropped for three quarters and margin is down with it.”
That sentence does two jobs. It helps you see whether a consultant listens and asks smart follow-up questions. It also stops a persuasive pitch from steering you toward a solution for a problem you don’t have.
It also helps to know what the role normally includes. Our overview of what a business growth consultant does covers the usual steps and deliverables, so you’ll recognize a complete offer when you see one.
How to Run the First Call
The first conversation is a working session, not a sales presentation. A little structure helps you get real information out of it:
- Open with your one-sentence problem. Then stop talking and see what they ask.
- Count the follow-up questions. Good consultants ask about your numbers, your team and what you’ve tried before they offer any opinion.
- Ask your 10 questions. Save the fee question for near the end, once you understand what they’d actually do.
- Ask for a short written summary. A good candidate can send back your problem, their proposed approach and a rough scope within a few days.
That written follow-up tells you a lot. If it clearly reflects what you said, they were listening. If it reads like a generic brochure, they weren’t.
10 Questions to Ask a Business Growth Consultant
Use the same questions with every candidate. Take notes on the answers, and pay attention to how specific they are.
1. What Kinds of Businesses Have You Helped Grow?
Listen for company size, stage and type of problem, not just industry. A consultant who mostly works with large corporations may struggle with a 15-person company where the owner still handles sales.
2. Can You Walk Me Through Your First 30 Days?
A strong answer is concrete: what data they’ll ask for, who they’ll interview, and when you’ll see a first diagnosis. A vague answer (“we’ll get to know the business”) suggests there’s no real method.
3. How Will You Find Our Biggest Constraint?
You want to hear about numbers, interviews and testing ideas against data. Be cautious if they already seem to know the answer before looking at your business.
4. What Exactly Will I Receive?
Ask for a list of deliverables, such as a diagnostic summary, a written plan, a dashboard or process documents. If they can’t name them, you’ll have a hard time judging whether the engagement worked.
5. How Involved Are You in Implementation?
Some consultants hand over a plan and leave. Others work beside your team for months. Neither is wrong, but you need to know which you’re buying and whether your team can carry out the plan alone.
6. How Will We Measure Success?
A good consultant will suggest two to five measurable targets tied to your problem, like close rate, gross margin or cash on hand. Agree on them before work starts, not after.
7. Who Will Actually Do the Work?
At larger firms, the senior person who sells the engagement may not be the one doing the work. Ask to meet whoever will lead your project day to day.
8. How Much Time Will This Take From Me and My Team?
Honest consultants will tell you plainly. Expect more of your time early on, during discovery. If they say it will take almost none, be skeptical, because real change always needs the owner’s attention.
9. How Is the Fee Structured, and What If It Isn’t Working?
Ask how they price, what’s included, how extra work is billed, and how either side can end the engagement early. For context on the common models, see our breakdown of how much a business consultant costs.
10. Can I Speak with Two or Three Past Clients?
References are standard. Ask the references what problem they hired the consultant for, what changed, and what they wish had gone differently. That last question tends to get the most honest answers.
Key takeaway: The best sign of a good consultant isn’t a polished pitch. It’s specific, confident answers about method, deliverables and measurement, plus a willingness to say what they don’t know.
Red Flags to Watch For
Some warning signs should end the conversation, however good the rest of the pitch sounds:
- Guaranteed results. Promises like “we’ll double your revenue in six months” are a sales tactic, not a forecast.
- The same answer for everyone. If the solution is ready before they’ve seen your numbers, it isn’t tailored to you.
- No questions about your data. A consultant who doesn’t ask for financials can’t diagnose anything.
- Pressure to sign quickly. Limited-time discounts and “only one spot left” are signs of a sales process, not a partnership.
- No references or vague case stories. Experienced consultants can connect you with past clients.
Hold consultants to the same standard you’d hold any business claim. The FTC’s advertising and marketing guidance expects businesses to back their claims with evidence, and a consultant’s pitch should meet that bar too.
How to Compare Consultants Side by Side
After your calls, score each candidate from 1 to 5 on the same five criteria. This keeps you from choosing on charm alone.
| Criteria | What a 5 Looks Like |
|---|---|
| Relevant experience | Has solved your type of problem for companies of your size |
| Clear method | Can explain the first 30 days in detail |
| Concrete deliverables | Names specific outputs and dates |
| Implementation support | Matches the level of hands-on help your team needs |
| Fit and communication | Listens well, explains simply, and you’d trust them with bad news |
Here’s a hypothetical example. A specialty food manufacturer is choosing between two finalists. Consultant A scores 4, 5, 4, 5 and 4, for a total of 22 out of 25. Consultant B scores 5, 3, 3, 2 and 4, for a total of 17.
Consultant B has stronger industry credentials, but Consultant A has a clearer method and will do much more implementation, which matters more because the manufacturer’s team is already stretched. The scorecard makes that trade-off easy to see.
After You Choose: Set the Engagement Up Well
Even the right consultant can struggle if the start is loose. Before work begins, put three things in writing: the targets you agreed on in question 6, the deliverables and dates from question 4, and a review point (often around 30 or 60 days) where you both decide whether to continue as planned.
Then tell your team who the consultant is, why they’re here and what you need from each person. Staff who understand the purpose share better information, and that makes the diagnosis faster and more accurate.
Where to Find Good Candidates
Start with referrals from owners you trust, especially those who have been through a similar growth stage. Industry associations and your accountant or banker can also point you to people with a track record.
For free advice while you search, the SBA’s local assistance finder connects you with small business development centers and mentors in your area. Some owners use that support to clarify their problem before hiring paid help.
If you’d like to put these questions to a business growth consultant directly, you can start at 20xBusiness.com. We welcome them on the first call, because a consultant who can’t answer them clearly isn’t ready to work on your business. You can also review how we approach growth strategy engagements before you talk to us.

Frequently Asked Questions
Should a business growth consultant have experience in my industry?
It helps, but it matters less than experience with your type of problem and your company size. A consultant who has fixed sales conversion in many service businesses may help you more than one who knows your industry but not your problem.
How many consultants should I talk to before hiring one?
Two or three is usually enough. Fewer gives you nothing to compare against, while more tends to slow the decision without adding much. Use the same questions with each so the answers are easy to compare.
What should a business consulting agreement include?
At a minimum: the scope, deliverables, timeline, fees and payment terms, what happens if extra work is needed, confidentiality, and how either side can end the agreement. If any of these are missing, ask for them in writing.
