I'm going to do something a little unusual here and tell you how to be suspicious of people like me.
The consulting industry doesn't have a licensing board. There's no bar exam, no certification that actually means anything, no minimum standard of competence. Anyone can call themselves a consultant. Some of them are excellent. Many of them are mediocre. A few of them will actively waste your time and money.
Since I can't fix the industry, the least I can do is help you navigate it.
They can't tell you what you'll get
This is the biggest one. If you ask a consultant "what will I have at the end of this engagement?" and the answer is vague, walk away.
"We'll develop a strategy." What does that mean? A document? A presentation? A napkin sketch? What's in it? How long is it? What decisions will it help you make?
"We'll identify opportunities for improvement." Great. Will you also help me act on them, or is identifying them the whole gig?
A good consultant can describe their deliverables in specific, concrete terms. A Flow Check produces a written report with process maps, identified bottlenecks, and prioritized recommendations. You can hold it in your hands. You know exactly what you're paying for.
If someone can't describe what you'll get, it's because they don't know. That should worry you.
They bill hourly with no estimate or cap
Hourly billing creates a strange incentive. The longer a project takes, the more the consultant gets paid. I'm not saying everyone who bills hourly is padding their hours. But the structure rewards slow work, and structures matter more than intentions.
Beyond the incentive problem, open-ended hourly billing means you don't know what the project will cost. You're writing a blank check. That's a bad position for anyone to be in, especially a small business watching its budget.
Ask about pricing structure upfront. If it's hourly, ask for an estimate and a cap. If they won't give you one, they either don't know how long it'll take (which means they haven't scoped the work properly) or they don't want to commit (which should make you nervous).
They use a generic framework for everything
Some consultants have a framework they learned at McKinsey or Deloitte or wherever, and they apply it to every business they touch. Doesn't matter if you're a restaurant or a tech startup or a landscaping company. You're getting the same matrix, the same quadrants, the same process.
Frameworks can be useful starting points. But your business is not a case study. It has specific people, specific constraints, specific history. A consultant who doesn't take the time to understand those specifics before recommending things is giving you generic advice at custom prices.
If someone starts talking about their proprietary methodology before they've asked you a single question about your business, that's a red flag.
They only advise, never implement
Here's a pattern I've seen too many times. Consultant comes in, spends weeks interviewing people and analyzing data, produces a beautiful report with smart recommendations, presents it in a nice meeting, and then leaves.
Six months later, nothing has changed.
The recommendations were probably good. The problem is that knowing what to do and actually doing it are completely different skills. Implementation is messy. It requires being in the trenches, adjusting things when they don't work, helping people through the discomfort of changing how they work.
Ask any consultant you're considering: do you help with implementation, or do you just advise? If they just advise, you need to be honest about whether you have the bandwidth and skill to implement on your own. Sometimes you do. Often you don't.
They make you dependent on them
Good consultants work themselves out of a job. They build things that run without them. They train your team. They document everything. They leave you more capable than they found you.
Bad consultants, sometimes intentionally and sometimes not, create dependency. They build systems that require their continued involvement to maintain. They hold knowledge in their heads instead of transferring it. They structure engagements that never really end.
This one's tricky to spot in advance. But you can ask: what does the handoff look like? What will my team be able to do independently after you leave? How do you ensure we're not reliant on you going forward?
If the answers are fuzzy, or if they seem uncomfortable with the idea of you not needing them anymore, pay attention.
They oversell and underdeliver
"We'll double your revenue." "We'll completely restructure your operations." "Your business will be unrecognizable in 90 days."
Run.
Real business improvement is incremental. It's important and sometimes dramatic, but it doesn't happen in a lightning bolt. Anyone promising radical overnight results is either delusional or lying, and neither one is someone you want to hire.
A good consultant will be honest about what's realistic. They'll tell you what they think they can help with and what's outside their scope. They'll set expectations that they can actually meet.
They talk more than they listen
In any initial conversation with a consultant, pay attention to the ratio. How much are they talking versus asking? Are they pitching you, or are they trying to understand your situation?
A consultant who leads with their credentials, their client list, their methodology, and their success stories before asking you a single substantive question about your business is telling you something. They're telling you that their process matters more than your specifics.
The best consultants I've known, the ones I've learned from and tried to emulate, are relentless askers. They're genuinely curious. They assume they don't understand your business until you've explained it to them, because they don't.
What good looks like
I don't want to leave you only with a list of what to avoid. Here's what you should look for instead.
Clear deliverables, described in plain language. A pricing structure you understand before you commit. Genuine curiosity about your specific situation. A track record they can back up with specifics, not just testimonials. Willingness to implement, not just advise. A plan for handoff that leaves you independent. And honest conversation about what they can and can't do for you.
No consultant is perfect. I'm certainly not. But these basics should be table stakes, and the fact that they're not is exactly why I wrote this post.
