      Lead Generation Review from Patrick Benasillo

      Belkins nailed project management. Each stage of the outbound funnel was thoroughly calculated, allowing us to use data-driven insights to make informed decisions and making sure both sides implemented strategies effectively. Communication was clear and proactive, and they maintained full transparency throughout the process. In the first month, we closed our first contract, which was a promising start. Belkins helped us build a robust sales pipeline. Currently, we have four opportunities at the proposal stage, averaging $85K, with the potential for these contracts to grow up to $150K. We didn't expect to close deals and contracts so quickly. Belkins exceeded our expectations by not only creating a solid base for future work but also securing contracts right off the bat. Their ability to deliver quick and substantial results was very impressive.

      Appointment Setting Review from Rafael

      Belkins played a crucial role in refining our customer profile and identifying key features of our ideal buyer. It meticulously researched relevant leads to construct a targeted contact list. Our partnership with Belkins commenced in May 2023, and by February 2024, it secured 51 appointments for us. With an impressive 43% open rate and a 3.7% reply rate, we exclusively focused on the United States market and the architecture industry. Thanks to Belkins' efforts, we expanded into the Canadian market and explored opportunities in other industry sectors. Hiring Belkins as our lead generation specialist ensured a consistent influx of new clients. We were impressed with the agency's efficient strategies.

      Belkins helped us define our ideal customer and find the right leads. They created targeted email sequences that highlighted our value in different ways. We started our collaboration 6 months ago and Belkins set 36 appointments for us. We saw a 57% open rate and a 5-6% reply rate. We focused on the U.S. market but now we're starting to expand to Canada and some European countries.

      White Glove Service: A clean pair of white gloves portrays the cleanliness of the wearer and the household. They gave rise to the related "white glove test," which involves running one's finger across a surface without besmirching the perfectly white glove.Today, white-glove service provides an exceptional experience. Altruic exceeds clients’ expectations, prioritizes their needs, personalizes their experience, genuinely cares about their happiness and satisfaction, and resolves problems before they arise. I recommend them without reservation.

      The Kanthal Group provided outstanding leadership coaching for two of our new leaders. Their approach was organized, direct, and highly effective, while also being supportive and encouraging throughout the process. They took the time to understand our goals and tailored their coaching to meet the specific needs of each leader.What stood out most was how easy they were to work with. Darren and Rachel are professional, responsive, and focused on delivering meaningful results. The coaching helped build confidence, strengthen leadership skills, and accelerate development. I would highly recommend The Kanthal Group to any organization looking to invest in leadership growth and development.

      I initially reached out to Rachel during a season when my business felt stuck, and I needed clarity and direction. What I found was so much more than business coaching. Rachel helped me tap into my own instincts, strengths, and creativity in a way I hadn’t experienced before.She’s honest and direct, but in a way that feels empowering rather than critical. Her ability to challenge limiting thinking while still making you feel supported is a rare gift.Since working with her, I’ve uncovered multiple business ideas and possibilities that I genuinely didn’t know were in me. More than anything, she’s helped reignite my motivation, confidence, and hope for what’s possible in both my business and my life. I’m incredibly thankful for her guidance and support.

      I can’t say it enough if you have ever considered getting a coach I highly recommend Rachel. She is a fantastic coach. When we first started working together I wasn’t really sure where to begin. I recall our first conversation and just throwing a lot of thoughts out there. She helped dig in and reframe the underlying situation and goal. Each call was the same. She would ask so what do you wanted to be coached on today, I would say I really don’t know here are the items on my mind and by the end of the call I was like wow I didn’t know which direction I should go in but she knew exactly where I needed you be. I left every calling feeling 10x more confident in where I was, where I was headed, and what I needed to do to get there. She is an invaluable resource! Again I highly recommend!

      Dreamscape Hero's Review Sourced from Google

      My wife and I used this firm to prepare our taxes one year on a family recommendation and they were a total joke. We had to send back our taxes twice because they couldn't even get our names right the first time, and the second time they didn't get our Social Security Numbers right. Given the fact that we sent them our previous two years of returns with our names and SSNs correctly printed all over the returns, it's astounding that such basic errors happened. Who knows what other errors were on that year's returns... On top of that they charged $500 for a very basic return and basically required us to fill out all the boxes on our forms instead of taking all the forms and preparing the taxes. We had to spoon feed them everything and basically did our taxes ourselves. Suffice it to say we never used them again after that.

      EIDE BAILLY CHARGED ME $1,325.00 FOR A STANDARD TAX RETURN!!!I had been using Eide Bailly since I graduated college a few years ago. David Frank was always the guy I dealt with, and it was always expensive, and never impressive. I would have to pay about $600 if I recall for a standard tax return in the past. PLUS I would call with what seemed like a simple question during the year and he would "need to check". After hours passed he would call back with an answer and a bill would sometimes follow for something like $100.In April 2012 David Frank did my taxes as usual, but when the bill came it was for $1,325.00 !!!!!! I was shocked, he said it was because I had got married in 2012 and he "HAD TO CALL" ANOTHER GUY AT ANOTHER EIDE BAILLY IN MINNEAPOLIS, MN TO BE SURE THAT DID NOT REQUIRE SPECIAL CONSIDERATION ON THE TAX RETURN... AND HE BILLED FOR HOURS OF TALK TIME *TIMES* 2 PEOPLE. And the answer was **NO THIS DOES NOT AFFECT THE TAX RETURN!!** IT WAS A WASTED CALL!! And they billed my and my new wife $1,325.00!! Do you know how much that is to a couple newly weds!!!I asked David if he felt that was fair, and he said YES!!!

      As an accounting firm I would give them 1 star. I recently discovered a litany of deductions they failed to consider. You will be given an EA, which is just a glorified tax preparer. They will know nothing and be slow to reply. You might as well get your taxes done by H&R block or a proper independent CPA. If these folks do your taxes, get prepared for a larger tax bill. I strongly advise against it.

Frequently Asked Questions

What types of problems do consulting agencies typically solve?

They usually solve problems that are too important, too cross-functional, or too urgent for an internal team to handle alone. Business owners hire business consultants when they need to grow, improve execution, manage risk, or change how the business runs.

  • Strategy and growth problems: Businesses hire a strategy consulting firm when they know the current path is not strong enough, but have not yet agreed on the next move. PwC’s 2025 Global CEO Survey found that 42% of CEOs say their company will remain viable for less than 10 years if it stays on its current path. Organizations rely on business consulting agencies when they need help with their growth strategy and when they want to learn how to compete.
  • Digital transformation and technology gaps: Business consulting firms help businesses turn technology spending into measurable operating results. Gartner reported that only 48% of digital initiatives meet or exceed their business outcome targets. McKinsey reported that 78% of organizations use AI in at least one business function, yet more than 80% say they are not seeing a tangible enterprise-level EBIT impact from generative AI.
  • Operational performance problems: Consultants help with low productivity, weak margins, slow throughput, poor planning, supply chain instability, inventory problems, and uneven service delivery across business units or geographies. They redesign processes, improve decision rights, cut waste, and build a more resilient operating model.
  • Organizational and talent issues: A business consulting company can redesign organizational structure, clarify accountability, improve governance, support transformation offices, and build workforce capability. ManpowerGroup reported that 72% of employers are having difficulty filling roles, based on a survey of 39,000 employers across 41 countries. Consulting work increasingly includes workforce planning, reskilling, and change management, not just strategy decks.
  • Risk management, resilience, or crisis exposure problems: A consulting firm helps with cybersecurity, regulatory response, geopolitical shocks, technology disruption, and business continuity. According to IBM, the global average cost of a data breach reached $4.88 million, and 70% of breached organizations said their operations were significantly or moderately disrupted. When risk starts affecting operations, cost, customer trust, or board-level decisions, companies often bring in consultants because they need both specialist expertise and fast execution.

How much do business consulting services cost?

Business consulting costs vary widely depending on the type of firm, the problem being solved, and the pricing model.

Hourly rates

  • Small business consultants: $75
  • General business consultants: $100-$250
  • Experienced specialists: $250-$500+
  • High-end or niche experts: $500-$1,000+

For ongoing advisory or support, business consulting firms charge monthly fees:

  • Small business retainers: up to $2,500/month
  • Mid-market or specialized retainers: $5,000-$25,000+/month

Top-tier consulting firms such as Deloitte Consulting LLP and McKinsey consultants charge differently, since they bill clients for the entire team's fee rather than individual fees.

  • Pricing is often $100,000 to $1M+ per project
  • Weekly team costs can reach tens of thousands of dollars, depending on seniority and scope

What should be included in a consulting proposal?

Business consultants should provide a strong proposal that removes uncertainty for the client. It should clearly define the problem, the approach, the expected outcomes, and the commercial terms.

A strong consulting proposal should answer four questions clearly:

  • What problem are you solving?
  • How will you solve it?
  • What results should we expect?
  • What will it cost and how long will it take?

How do I avoid getting locked into a long-term consulting relationship that doesn’t deliver measurable value?

You need to structure the relationship around clear outcomes, short commitments, and accountability from the start. Most consulting projects don't succeed because of unclear expectations and weak performance tracking. According to McKinsey & Company, only about 30% of large business transformation programs fully achieve their goals, often due to unclear objectives and weak tracking.

You should set a clear baseline, define target improvements, and agree on a timeline. For example, instead of saying you need to improve operations, set the goal to reduce operating costs by 10% within six months.

Avoid large upfront commitments and start with a short diagnostic or pilot phase, which can last 4 to 8 weeks, and include a formal review point before moving forward.

Define a clear scope of work and deliverables. The agreement should specify exactly what the business consulting firm will deliver, when those deliverables are due, and what is explicitly out of scope.

To avoid long-term dependency, require knowledge transfer to your internal team. This includes documentation, tools, and training that allow your staff to operate independently after the project ends.

What results should I realistically expect from a consulting agency?

Business consulting companies should offer a measurable business impact. Depending on the project, a measurable business impact may include cost reduction, revenue growth, improved margins, faster processes, or higher productivity.

A good consulting agency should deliver clear strategic direction, measurable performance improvements, faster execution, specialized expertise, and lasting internal capabilities. You should expect expert knowledge that will help your organization become more capable than it was before.

What information should I prepare before reaching out?

Prepare enough information to clearly explain your problem, your goals, and your current performance, so that the agency can assess the fit quickly and give you a realistic proposal.

At a minimum, you should be ready to share: 

  • A clear description of the problem (what’s not working, where, and why it matters)
  • Your business goals (what success looks like in measurable terms)
  • Key performance data (revenue, margins, growth trends, or operational metrics)
  • Any existing initiatives or strategies already in progress
  • Your budget range and expected timeline
  • Who the key decision-makers are

What is the difference between boutique consulting firms and large consultancies?

The difference comes down to scale, specialization, cost, and how work is delivered. Boutique business consulting firms tend to be focused and flexible, while large consultancies offer broader capabilities and global reach.

Boutique consulting firmsLarge consultancies 
Focus on a specific industry or problem (e.g., pricing, supply chain, AI).Offer a wide range of services across industries (strategy, tech, operations, risk).
Small, senior-led teams with direct involvement from experienced consultants.Larger, layered teams (partners, managers, analysts) with more standardized delivery.
More adaptable, faster decision-making, and customized approaches. Strong global presence, established frameworks, and ability to handle large, complex transformations.
Often more cost-efficient for targeted projects.Higher fees due to brand, scale, and large team involvement.
Deep focus on specific problems with hands-on execution.Structured methodologies, often combining strategy with large-scale implementation programs.
