50 Profitable Consulting Business Ideas For 2021

50 Profitable Consulting Business Ideas For 2021

Interested to start a consulting business but not quite sure what to start?

The good news is, there are so many opportunities to become an entrepreneur and provide a worthy service in this line of work.

If you're looking to start your own consulting business, there are several low-investment options you can choose from.

We put a list together below of the most profitable consulting business ideas you can start today!

Here they are:

1. Start a fashion consulting business ($42K/year)

Susannah Davda from Bromley started The Shoe Consultant Ltd about 6 years ago, a fashion consulting business.

  • Revenue: $3,500/ month
  • Founders: 1
  • Employees: 1
  • Location: Bromley

Except for a paper round and a brief stint in a horrible bag shop, I have only ever worked in shoes. At the age of sixteen, I started working in a shoe shop. Although the product was pretty average, I loved it when new styles were delivered. I got a kick out of seeing the transformation of customers trying on different shoes. I didn’t even mind the monotony of “working stock” - climbing up and down ladders shifting heavy shoe boxes from one set of shelves to another.

When I was looking for fashion design degree courses in the great big manual of university options, I stumbled across the tiny Footwear Design section. There were two footwear design degree courses and an HND in the UK. I applied for all three!

During my undergraduate degree, I learned to design, make, and cut the patterns for shoes. When I graduated, I worked in design and buying, then product management. I had experience in retail, wholesale, and branded footwear, and I knew I wanted to use my knowledge to help people.

2. Start a technology consulting business ($480K/year)

David Bishop from Atlanta, Georgia, USA started Agile Worx ago, a technology consulting business.

  • Revenue: $40,000/ month
  • Founders: 1
  • Employees: 3
  • Location: Atlanta, Georgia, USA

I started programming at age 13 on a Commodore VIC-20 personal computer. I enjoyed taking the thing apart as much as I did creating my own games. It was at that time that I decided I wanted to be a computer engineer. I spent years taking the hardest math and science classes available and eventually managed to get into a top tier engineering school. One of the greatest attributes of a career in technology is that you are always learning, and for many years, I certainly did. However, after my first decade in the business I began to realize two things:

  1. There was no knowledge equity in what I was doing. Unlike medicine or law, the knowledge I accumulated over time lost value, instead of gaining value, because the technology changed so much. I would spend months becoming an expert on something only to find that knowledge obsolete in a couple of years. Even though learning was fun, I started to feel as though I was treading water and throwing my life away.

  2. The business was changing drastically - for the worst. Most of the work was being outsourced overseas to lesser educated and experienced people, and companies I worked with started experiencing severe quality and performance problems. After the “.com bubble” bust in the early 2000s, wages and career opportunities stagnated. I realized that I had to make a change.

3. Become an it consultant ($25.2K/year)

Dan Khadem from Denver, Colorado, USA started Access Database Support over 9 years ago, a IT consultant.

  • Revenue: $2,100/ month
  • Founders: 1
  • Employees: 1
  • Location: Denver, Colorado, USA

The database consulting was a natural progression from my day job. People were asking me for help on projects outside of my workday so the work fell into my lap. It was then that I realized I could turn this skill into something for real on the side.

Look at your business idea as a brick wall that needs to be built brick by brick. Don’t get overwhelmed by the amount of things that are involved in starting a business or side hustle. Instead just focus on the one brick in front of you. Go slow and steady. Be sure to add a new brick to that wall every single day.

At the time I started doing the side work I was in massive debt from school. I was already paying for my lifestyle through my regular job so I knew any income I earned on the side could go to directly paying off my student loans. It worked. I paid off my loans a few years ago and now have the flexibility to use my side income for other things.

4. Become a business law consultant ($4.5M/year)

Anthony Rose from London, England, United Kingdom started SeedLegals over 4 years ago, a business law consultant.

  • Revenue: $375,000/ month
  • Founders: 3
  • Employees: 40
  • Location: London, England, United Kingdom

I used to head up BBC iPlayer. After leaving the BBC, I built a startup -sold it- built another startup -sold it. I then invested in a few startups and got tired of paying lawyers. In a stroke of luck, I met my business partner Laurent Laffy, serial angel investor, and ex-VC.

We got together and decided it was time to transform the way we do funding rounds.

5. Start a resume writing business ($30K/year)

Mike McRitchie from El Dorado, California, USA started Critical Path Action about 6 years ago, a resume writing business.

  • Revenue: $2,500/ month
  • Founders: 1
  • Employees: 0
  • Location: El Dorado, California, USA

Over the years I’ve built quite a bit of business knowledge (was a Director of Operations and helped build a company from 5 employees to 100 and $2.5 million to $16 million in revenue; also was a five-year member of Vistage, a business mastermind group) and wanted to leverage that.

Get started with something inexpensive that interests you. Then keep going as you try things and learn.

I started a website through an online marketing/website building course and began blogging on business and career topics. But I found monetizing that to be difficult. I wanted to do business strategy consulting and paid $1,000 for a three-month insert in a coupon mailing that did nothing and found trying to get that type of consulting off the ground part time around my day job wasn’t working.

6. Become an online dating consultant ($62.4K/year)

Shane White from Austin, Texas, USA started The Match Artist over 3 years ago, a online dating consultant.

  • Revenue: $5,200/ month
  • Founders: 2
  • Employees: 0
  • Location: Austin, Texas, USA

I have always been an entrepreneur. When I was in high school, I wanted to start my own business, so I took to one thing that I knew how to do- mow lawns.

Afterward, while I was in college, I started a mobile DJ business, which was a great way to earn some extra cash in college. After graduating from NDSU with a degree in Computer Science, I took a full-time job working as a software developer. While working as a developer, I really wanted to start a SaaS Company, which translates to “Software as a Service”, so I did just that. I created Midwest Streams - Simple Funeral Webcasting, which helps funeral directors webcast their funerals.

I ended up spending too many hours working on Midwest Streams while I was at my software developer job, so my employer fired me. (If you are reading this, I really am sorry!) This happened in February of 2014, and Midwest Streams was only making $400 a month. I decided not to go back to work and try my hardest to grow my company. I had some savings, but burnt through it pretty quick, as it’s really hard to survive with only $400 a month.

7. Start a ppc consulting agency ($36K/year)

Paul Franklin from Bath started SideGains almost 2 years ago, a PPC consulting agency.

  • Revenue: $3,000/ month
  • Founders: 1
  • Employees: 1
  • Location: Bath

I started my business in 2015 when I was made redundant as a result of business restructuring. Luckily for me, someone who I knew through a past business relationship in the industry heard about this and head-hunted me as a contractor to run his PPC campaigns. So I walked straight from redundancy into a contracting position.

I’d recommend making plans and setting targets. If you just work without something to aim for you’ll just coast along and without a sense of achieving things you’ll struggle.

In a sense I hadn’t planned on becoming a business owner, it just sort of happened naturally. Had I never been made redundant, I might still be an employee.

8. Become a college counselor ($600K/year)

Pradeep Gaddam from San Jose, California, USA started ConnecPath over 3 years ago, a college counselor.

  • Revenue: $50,000/ month
  • Founders: 2
  • Employees: 1
  • Location: San Jose, California, USA

I started my career as a researcher at NASA where I helped scientists visualize data. It did not take long before I realized that research is not a place for me. I thought to join a big company would make it exciting for me, I then joined Intel Corporation only to realize that's not a place for me. It took me 10 years to realize that being an entrepreneur is where I felt more fit and excited. I always knew, If I had the right mentor I would not have wasted 10 precious years.

All this made sense to me, when I met my co-founder over a beer, he mentioned an interesting data point to me. The ratio between a high school counselor and students is 1:500, which means the amount of time, a student gets over their entire high school is 38 minutes. That clearly is a huge problem and interestingly of all the high school students that get into colleges, 40% of them either end up changing majors, colleges, not graduating on time or not graduating at all.

I think that's a very serious problem. I instantly connected with that problem and we decided that we will certainly fix it. That’s how we started on this journey.

9. Become a facebook ads consultant ($36M/year)

Kean Graham from Vancouver, British Columbia, Canada started MonetizeMore over 11 years ago, a Facebook ads consultant.

  • Revenue: $3,000,000/ month
  • Founders: 1
  • Employees: 160
  • Location: Vancouver, British Columbia, Canada

I originally fell in love with the online industry when working for a large online classified network. The job was an immense learning experience but once the recession hit, the company decided to lay off the marketing department. I lost the best job I ever had but I was determined to turn the bad into something great.

With the devotion to improve a little bit every single day, one can accumulate incredible improvement and success.

Five days later, I'm on a plane to South America to go on a life changing trip. Four months into my backpacking trip I was on a four-day trek through the incredible Inca trail towards Machu Picchu. By the end of it, I was sitting on top of Wayna Picchu reflecting on my experiences throughout my trip. I have had the most fulfilling time of my life and it finally clicked:
