How to Start a Consulting Business: A 90-Day Project Plan

Key takeaways

Starting a consulting business is a small project, not a leap of faith. It has a goal, a deadline, a budget, a few risks and a way to know whether it worked. That is why a 90-day plan beats a year of "getting ready."
Spend the first two weeks choosing who you help and what result you sell, in one sentence. Everything else, from the website to the price, gets easier once that sentence exists.
The paperwork (entity, tax number, bank account, insurance, a contract) is real but small. Check it with a CPA and an attorney in your state, and do it in week three, not in week one.
Price in a way you can defend, then talk to at least ten real people before you decide the offer is wrong. Most first offers fail in conversation, not on a spreadsheet.
Watch three numbers every week: conversations held, proposals sent and money in the bank against your runway. Day 90 is a review, not a verdict.

Every new consultant buys the same three things in the same order. First a domain name. Then a logo, which takes a lot longer than expected because the circle looks "too corporate" and the square looks "too bank." Third, if everything goes well, a client, which was supposed to be the first thing and arrives, as a rule, after the business cards.

I understand the instinct. A domain and a logo are tangible. You can look at them, show them to your cousin and feel like something has started. A client is slippery: it depends on another person saying yes, usually on a Thursday afternoon when they were about to leave early. So we begin with what we can control, and what we can control feels productive and has almost no effect on whether the business works.

Here is a different way to look at it. Starting a consulting business is a project. Not a metaphor of a project, an actual one: it has an outcome you can describe, a date by which you want it, a limited amount of money and time, a handful of things that could go wrong and a moment at which you decide whether it was worth it. I help people run projects for a living, and the day I stopped treating "starting a business" as a mood and began treating it as a plan with dates, the whole thing became calmer and, more importantly, measurable.

This article is that plan, in 90 days, built for someone who wants to sell advice, expertise or project work without lighting their savings on fire. It is not legal or tax advice, because I am not your attorney or your accountant, and the rules differ by state. It is the project-management layer around those: what to do, in what order, and how to know if you are on track.

Why 90 days, and why a project

Ninety days is long enough to have real conversations, send real proposals and probably sign something. It is short enough that you cannot hide in preparation forever. Preparation is the most comfortable form of procrastination, because it feels like work and nobody can tell you that you are doing it wrong.

Treating it as a project gives you three things most new businesses do not have:

A definition of done. "Start a consulting business" has no finish line. "In 90 days, have signed one paying client and talked to at least ten qualified prospects" does.
A stop-and-review point. On day 90 you look at the numbers and decide: continue, adjust or stop. Without that date, businesses either drift for two years or get abandoned on a bad Tuesday.
A rhythm. A 30-minute review every week is more powerful than a heroic weekend once a quarter. It is the same idea as a weekly review for any project, applied to your own career.

If you have read about the 90-day sprint for startups, this will feel familiar. The sprint is the engine, and this article is the engine pointed at one particular goal: a first paying client.

Before day 1: write a one-page charter

Take one page and answer six questions. This is a small version of the project charter, and the first time you write one for your own business is surprisingly clarifying.

Purpose. Why are you doing this? "I want freedom" is honest but not useful. "I want to replace two-thirds of my salary within a year while keeping evenings free" is a purpose.
Objective at day 90. One number and one date. For example: "One signed client and a pipeline of at least three real prospects by day 90."
Money. How many months of expenses can you cover with no income? That is your runway, and it decides how patient you can afford to be.
Hours. How many hours a week can you really give? Be honest. If the answer is eight, the plan is eight hours long.
Out of scope. What you will not do in these 90 days: build a course, hire anyone, rent an office, redesign the logo again.
Decision rule. What result on day 90 makes you continue, adjust or stop?

That last item is the most uncomfortable and the most useful. Deciding the rule while you are calm is a gift to the person you will be on day 89, who will be tired and tempted to change the rules.

Two people shaking hands across a small cafe table with laptops and coffee cups, a consultant meeting a small business owner for the first time — Most of the work of your first 90 days happens across a small table like this one.

Days 1 to 14: choose who you help and what result you sell

The most expensive sentence in consulting is "I help businesses grow." It sounds safe and it says nothing. Nobody wakes up thinking "I need someone to help my business grow." They wake up thinking "my crew keeps missing deadlines" or "our onboarding takes six weeks" or "I do not know whether this project is on budget."

Spend the first two weeks finishing this sentence:

I help [a specific kind of person or business] achieve [a specific, measurable result] by [a method they can picture].

A few examples, to show the level of detail:

I help owners of small construction companies see their cost and schedule problems early by running a monthly project review.
I help clinic managers open new locations on time by planning the work backward from opening day.
I help founders of small tech companies stop missing deadlines by setting up a simple weekly rhythm and a one-page scoreboard.

Notice that each one has a person, a result and a picture of how. None of them says "strategy," "synergy" or "holistic," which are words that make prospects check their phones.

How do you choose? Three filters work well together:

Experience. Where have you actually solved this problem before? Real stories are your most valuable asset, and they are free.
Pain. Is the problem painful enough that people pay to make it go away, or merely annoying? Painful problems have budgets.
Reach. Can you name thirty people who have this problem and who you could reach through your network in a month? If not, the niche is too small or too far away.

Do not worry that a narrow niche will limit you. It will not. A narrow offer is easier to remember, easier to refer and easier to trust. Clients who fit will find you, and some who do not fit will find you too and you can decide what to do about them. You can widen later, and widening is far easier than trying to un-widen a vague brand.

By day 14, write the sentence, show it to three people you trust and ask only one question: "What would you picture if I said this?" If their picture differs from yours, change the sentence, not the people.

Days 15 to 30: the boring but necessary setup

Now comes the part everybody wants to start with, and the reason it is week three is that none of it matters if the offer is wrong. This is also where I must be clear: I am not a lawyer or an accountant, so treat this section as a checklist of questions to take to a CPA and an attorney in your state, not as instructions.

Business structure. Many solo consultants begin as sole proprietors, and many form an LLC or another entity for liability and tax reasons. Which is right depends on your state, your income, your risk and your clients. Ask a CPA and an attorney, and ask what it costs to set up and to maintain every year, because the second number surprises people.

Tax number and registrations. In the United States, an employer identification number (EIN) is free from the IRS, and you should be wary of any website that charges for it. State and city registrations, licenses and sales-tax rules vary. In Utah, the free resources listed in the Utah small business resource guide are a good starting map, including advisors who can explain the registrations without trying to sell you anything.

A separate bank account. Even before it is required by any structure, keep business money apart from personal money. It makes taxes, pricing and honest reviews far simpler.

A contract. Do not work without a written agreement. At minimum it should state the scope (what is included and what is not), the price and payment terms, how changes are handled, who owns the work and how either side can end the arrangement. Have an attorney review your template once. It is cheaper than learning these lessons from a client.

Insurance. Ask an insurance professional whether professional liability (sometimes called errors and omissions) and general liability coverage make sense for what you sell. Some clients will require proof of coverage before they sign.

A simple way to invoice and track time. Any basic tool is fine. The best one is the one you will actually use on Friday afternoon.

A website that explains the sentence. One page is enough in these first weeks: who you help, the result, how it works, two or three short stories and a way to contact you. You can build the rest later. A busy page you can change is better than a perfect site you have not launched.

The trap here is to turn setup into the whole project. A good test: if by day 30 you have a bank account, a contract template and a one-page site, you are ahead of schedule. If you also have a custom brand book, you are procrastinating with excellent taste.

Days 31 to 60: price it and talk to humans

This is the phase that decides everything, and it has two parts that must happen together: setting a price and holding conversations.

How to price in a way you can defend

There are three common models, and each suits a different kind of work.

Day or hourly rate. Simple and easy to compare, but it rewards time rather than results and it makes clients watch the clock.
Fixed project fee. The client pays one price for a defined result. It is easier to buy, but you carry the risk if the scope grows, which is why the scope creep guide matters so much here.
Monthly retainer. A fixed fee for ongoing access and a defined amount of work. It gives you predictable income and gives the client a steady partner.

Here is a quick way to find a starting number, using illustrative figures. Suppose you need $6,000 a month to live and run the business. In your first year, you will not bill every working day, because selling, writing proposals and learning take a large share of your time. If you can realistically bill about nine days a month, the number you need is roughly $670 a day, before taxes and before you account for slow months. Round up and add a safety margin. If that number makes you wince, that is useful information: either the offer must be priced by value rather than by day, or the runway needs to be longer, or the expenses are too high.

Then check the price against value. If you help a company save or earn $100,000, a fee of $10,000 looks different than if you help it save $15,000. Pricing by value requires that you can talk about the result in numbers, which brings us back to the sentence from week two.

The ten conversations

Here is the part nobody enjoys and everybody needs. Between day 31 and day 60, have at least ten real conversations with people who match your sentence, or who know many people who do. Not pitches. Conversations.

Start with your warm network: former colleagues, clients, suppliers, neighbors, people you met at industry events. The message is short and honest:

I am starting an independent practice helping [your people] with [your result]. I would love 20 minutes to hear how you handle this today, and whether it is a real problem for you. I am not selling anything on this call.

Then ask questions and listen. What does it cost them when it goes wrong? What have they tried? Who decides? What would a good outcome look like? Take notes. By the end of ten conversations, you will know three valuable things: whether the problem is real, what words people use for it (use those words on your website) and who might actually pay.

Some conversations will lead to a request for a proposal. Good. Send a one-page proposal within 48 hours: the problem in their words, the result, the approach, the price, the timeline and the next step.

A bright office wall with three columns of sticky notes in different colors representing three phases of a plan, a person adding one more note — Three phases, three columns. Moving a note to the right is the only kind of motivation that never wears off.

Days 61 to 90: the first client, the delivery system and the review

If you have followed the plan, around day 60 you have either a proposal in someone's hands or the realization that the offer needs adjusting. Both are good outcomes. The second is simply cheaper to discover now than at month eight.

If you have a client, treat the first engagement as a model for all the next ones. Before starting, agree in writing on the goal, the scope, the deliverables, the dates and how you will communicate. Set up a simple weekly update. A short written note every Friday ("done, next, blocked, decisions needed") builds more trust than a brilliant but silent three weeks.

If you do not have a client yet, look at where the conversations stalled. Was it the problem (not painful enough), the person (not the decision-maker), the price (too high for the result), or the timing (budget closes in January)? Adjust one thing and run another ten conversations. Do not change everything at once, or you will learn nothing.

Build a small delivery system. For each type of work you sell, write the checklist of what you do in the first week, the second, and at the end. It does not have to be fancy: it is the same checklist idea behind lightweight project governance. The point is to make your second client easier than your first.

Ask for evidence. After a first successful piece of work, ask the client for a short testimonial and for permission to describe the result (without confidential details). Future clients believe other clients far more than they believe you.

The day 90 review

Sit down with your charter and answer five questions in writing:

How many conversations did I have, and how many proposals did I send?
How much money has come in, and how does it compare with my runway?
Which part of my sentence was confirmed by real people, and which part was wrong?
What consumed my time that did not move the numbers?
Based on my decision rule, do I continue, adjust or stop?

Stopping is a legitimate result. A business that you test in a disciplined way for 90 days and decide not to continue costs far less than one that drifts for two years. And adjusting is the most common honest answer: keep the problem, change the audience, or keep the audience and change the offer.

The three numbers to watch every week

You will drown in tasks. Pick three numbers and put them where you will see them on Monday:

Conversations held this week. It is the leading indicator of everything else. A plan of ten conversations in 30 days is about three a week.
Proposals sent and their status. Open, won, lost and why.
Runway. Months of expenses left at the current burn, updated monthly.

The habit comes from the same logic as data-driven project management: measure the few things that change decisions, and ignore the rest. A scoreboard with three numbers beats a dashboard with twenty.

A short hall of fame of first-year mistakes

I have seen these often enough to name them, with affection:

The Perfect Logo. Three weeks, eleven drafts, zero clients.
The Everything Offer. "I do strategy, operations, marketing and sometimes plumbing." Nobody can refer you because nobody can describe you.
The Free Consultation That Never Ends. An hour becomes four, and the client is now consulting for free forever. Define a short first call and then propose paid work.
The Undercharge. Pricing low to win the first client, and then resenting the work. A fair price is part of the service.
The Handshake Project. No written scope, and a client who remembers a different handshake.
The Lonely Sprint. Working alone for 90 days with no one to say "that is not clear" or "that is a great idea." A peer group, a mentor or a simple weekly check-in with another person helps more than another course.
The Quiet Fortnight. Two weeks without a conversation because "I was building the website." This is where businesses go to die slowly.

Build your own 90 days

Use the tool below to place the main steps on the calendar. Choose your starting date and you will get a dated plan: the one-page charter, the sentence, the ten conversations, the paperwork questions, the first proposal and the day 90 review. Copy the dates into your calendar and move them as you learn. A plan you adjust is a plan that works.

What to do this week

Open a blank page and write your sentence: I help who achieve what by how. Then send one message to one person asking for 20 minutes. That is it. Not the logo, not the domain, not the business cards. One sentence and one message.

If you would like a second pair of eyes on your offer, your first-90-days plan or the way you run your first project, that is exactly the kind of work I do through Project Focus, and you can read how I think about what a business consultant actually does and when you may or may not need one. You can also see my services or write to me on the contact page. If you are building in Utah, the page about working with a business consultant in Utah explains how I work locally.

What is the one sentence you would use today to describe the business you want to start? Tell me in the comments.

More tools. The weekly review, the decision log and the risk register are free in the toolkit, and a project charter you can fill in online takes about an hour.

Frequently asked questions

How long does it take to start a consulting business?

You can finish the setup (a business structure, a tax number, a bank account, a contract and a simple website) in about four weeks. Getting the first paying client usually takes longer and depends on your network, your niche and your price. A 90-day plan with at least ten real conversations gives you a fair test of whether the offer works.

How much money do I need to start a consulting business?

The setup costs are often modest, but the number that matters is your runway: how many months of living and business expenses you can cover with no income. Many new consultants aim for three to six months, and more if their clients pay slowly. Ask a CPA to help you estimate the numbers for your situation.

Do I need an LLC before I start consulting?

Not always. Some people begin as sole proprietors, and others form an LLC or another entity for liability and tax reasons. The right choice depends on your state, your clients and your risk, so ask a CPA and an attorney before you decide. This article is not legal or tax advice.

How do I find my first consulting client?

Start with your warm network and ask for 20-minute conversations about a problem you can solve, not for work. Listen, write down the words people use, and send a one-page proposal to anyone who asks. Referrals and repeat conversations usually beat cold outreach in the first months.
