How to start a micro business

14 min read · updated 10 February 2026

A micro business is the smallest real business there is: one owner, often no employees, usually run from a kitchen table, a van, a laptop or a spare room. It is not a hobby and it is not a startup — it is a small, deliberate machine that trades something you can deliver for money someone is glad to pay.

This guide walks the whole path in order: what to sell, what to charge, what to register, how to get the first ten customers, and which three numbers to watch so the thing survives its first year. It is written for the owner who has a skill or a trade and wants it to become income, without a loan, a team, or a pitch deck.

1. Define the micro business in one sentence

Before anything else, write this down and keep it in sight:

I help (a specific person) get (a specific result) by (what I do), for (a price).

If you cannot fill that in, you do not have a business yet — you have an interest. The sentence does not need to be clever. It needs to be specific enough that a stranger could say yes or no to it.

Too vague: "I do social media for businesses."
Workable: "I run the Instagram and Google listing for one dental practice at a time, 20 posts a month, $900 a month."

The narrow version is easier to sell, easier to price, and easier to deliver well — which is the whole game when you are the only person doing the work.

2. Choose a model that fits your real life

Micro businesses usually fall into one of five shapes. Pick the one that suits your hours, your capital, and how much you like being around people.

Model	How it earns	Good fit if…	Watch out for
Service / trade	Hourly, day rate or fixed job price	You have a hands-on skill: cleaning, repairs, bookkeeping, tutoring, beauty, gardening	Income stops when you stop; raise prices yearly
Retainer	A monthly fee for ongoing work	You can commit to a steady slice of your week	Scope creep — define deliverables in writing
Product, small batch	Margin on physical goods	You can make or source consistently and ship	Cash tied up in stock; returns and postage
Digital product / content	Templates, courses, guides, ads or affiliate income	You can build once and sell many times	Slow start; needs an audience or a very sharp niche
Rental / asset	Renting out equipment, a room, a vehicle, a plot	You already own the thing and it sits idle	Repairs, insurance, and seasonal gaps

Most micro businesses mix two: a service that pays the bills plus a digital product that scales. That is a fine end state. It is a bad starting state, because doing two things badly is worse than one thing well.

3. Price it before you build it

The most common first-year failure is not laziness, marketing, or competition. It is arithmetic: the price never covered the real cost of delivering the work.

Do this calculation on paper:

Billable hours per week. Be honest. Out of a 40-hour week, a solo owner typically bills 20–25 hours. The rest is admin, travel, quoting, and marketing.
Cost of doing business per month. Software, insurance, phone, vehicle, materials, subscriptions, payment fees, a share of household costs if you work from home.
What you need to take home. Your actual number, not an aspirational one.
The floor rate. (Take-home + costs) ÷ billable hours. That is the price below which you are subsidising your customers.

Then add a margin for the work that goes wrong, the quotes that go nowhere, and the tax bill. A useful rule of thumb for a one-person service business: your quoted rate should be at least 1.5× the floor rate.

Two pricing habits worth adopting early:

Price the outcome, not the hour, wherever you can. "£450 to fix the leak and make good" is easier to sell and easier to deliver than "£60 an hour, maybe four hours, maybe seven."
Put a deposit in the quote. 25–50% up front is normal for trades, custom work, and anything with materials. It filters out the customers who were never going to pay.

4. Do the legal and tax minimum, then stop

This part is boring, quick, and entirely dependent on where you live — so treat the list below as the shape of the work, and check the specifics with your local authority or a local accountant.

Business structure. Sole trader / sole proprietor is the usual start: cheap, simple, and you file your business income with your personal tax return. Register a limited company or LLC when you want limited liability, or when customers insist on it.
Registration and name. Register the name where required, and check the domain and the social handles before you print anything.
Tax registration. Sales tax / VAT / GST registration usually has a turnover threshold. Below it you may not have to register — but track turnover from day one so you know the day you cross it.
Insurance. Public liability is the minimum for anything where you enter someone's property or handle their goods. Professional indemnity if you give advice.
Record keeping. One bank account for the business, all receipts in one place, photographed the day you get them. This single habit saves hours and money at year end.
Terms. A one-page set of terms: what you do, what you do not, when you get paid, what happens if a job is cancelled. Attach it to every quote.

You do not need a brand strategy, a logo suite, or a five-year plan. You need to be able to invoice, be insured, and prove what you earned.

5. Get the first ten customers without an ad budget

Micro businesses rarely grow from advertising. They grow from a small number of people who trust you, and from being findable when someone searches for exactly what you do.

The ten warmest doors, in order

People who already know your work. Former employers, past clients, the people who have watched you do this for years. Tell them what you now sell, in one sentence, and ask who else needs it.
Adjacent businesses, not competitors. The plumber knows every homeowner with a bad bathroom; the bookkeeper knows every freelancer who is behind on receipts. Offer a referral fee or return the favour.
Local, physical presence. A card in a shop window, a noticeboard, a van with a phone number. For home services this still outperforms most online ads.
One search-friendly page. A single page that names your town, your service, and your price range, with a phone number and a form. It does not need to be a masterpiece; it needs to load fast and answer the question.
A regular, useful post. One photo of finished work with two lines about what the job was, twice a week, on the platform where your customers actually are.

Ten customers is the milestone that matters, because at ten you can see the pattern: which offer they bought, what they asked before buying, and what they complain about afterwards. That pattern is your marketing plan.

6. Build the smallest possible back office

A micro business can run on four tools and a folder. Anything more is procrastination with a subscription attached.

Invoicing and expenses — one place that produces a numbered invoice and tracks what came in.
A calendar you actually check — with jobs blocked in as if they were appointments.
A single file per customer — quote, terms, notes, photos, invoice. Named consistently.
A weekly 30-minute review — money in, money owed, work booked for the next two weeks, one thing to fix.

Write down the repeatable parts of your work as you do them — the quote template, the checklist before you leave a job, the message you send after. Templates are how a one-person business gets its evenings back.

7. Watch three numbers, weekly

Number	What it tells you	Healthy direction
Cash collected this month	Money actually in the bank, not invoiced	Covering costs plus your pay
Money owed to you	How much of your work is sitting in someone else's account	Under one month of revenue
Booked work in the next 14 days	Whether next week is already safe	More than half your capacity

If cash and booked work are both fine, you can afford to experiment. If either is thin, your only job this week is selling — not redesigning the website.

8. The mistakes that cost micro owners the most

Discounting to win the first job. The price you open with is the price you will be known for.
Taking every job. A micro business dies of scope, not of hunger. Two bad clients can consume the week that one good retainer would have paid for.
No deposit, no terms. Chase-proof your work from the first invoice.
Spending on the shell. Logo, website, branded packaging — none of it sells a service nobody has heard of yet.
Not raising prices. Costs rise every year. If your price has not moved in two years, you have taken a pay cut.
Hiding from the numbers. A monthly hour with your own bank statement is the cheapest consultant you will ever hire.

9. A 30-day starting plan

Days 1–3: write the one-sentence offer, choose the model, work out the floor rate.
Days 4–7: register the business, open the bank account, buy the insurance, draft the one-page terms.
Days 8–14: build the single page, the quote template, and the invoice template. Tell twenty people you have started.
Days 15–21: do three jobs, even small ones, and photograph or document every one.
Days 22–30: ask each of those three customers two questions — "what made you choose me?" and "who else needs this?" Then raise your price for the next job if every one of them said yes without hesitating.

That is a micro business: small enough to start this month, real enough to pay you, and simple enough that one person can run it without a team. The rest is repetition.
