Entrepreneur's Guide · Kasvuvoima Oy
Starting a company feels big. It is a big thing, but it isn't complicated once you break it into pieces. This guide walks the whole journey, step by step, in plain language. No jargon, no scare tactics. Just what's worth knowing, in the order things actually come up, written for founders building a business in Finland.
Free and freely shareableThis guide is based on official Finnish sources, such as the Suomi.fi service, guidance from the Finnish Tax Administration (Vero.fi), and Business Finland's funding guidance. Always check the current details from the official sources, every link below points to the English page where one exists.
Part 1 · Before you start
The idea, testing it, and making sure the numbers hold up in daylight.
It all starts with an idea. But an idea isn't a business yet, it's a promise you have to make concrete: whose problem you solve, and who is willing to pay for it.
At this stage you don't need a logo, a website, or a company. You need clarity. Write it down: what problem, for whom, and why you. If you can fit that into one sentence a friend understands, you're further along than most.
How Kasvuvoima can helpIf you'd like a sounding board to sharpen the idea, just ask us, we reply by email, free of charge. See services.
The Suomi.fi service offers an official checklist on skills, finances and dealings with the authorities, including a dedicated section for foreign entrepreneurs.
Before you put money and months on the line, find out cheaply: does anyone actually want this? This is the entrepreneur's most important, and most underrated, skill.
Talk to potential customers. Don't ask "would this be nice?", everyone says yes to be polite. Ask what they do now, what annoys them about it, and how much the problem costs them. A small test page and one targeted ad tell you more than a hundred opinions.
How Kasvuvoima can helpIf you need it, we'll set up a lightweight test page and a small ad experiment within a week, so you get real data on demand. See services.
Planning your business idea and market is covered in Suomi.fi's business-planning section, including assessing demand, competition and pricing.
Now we look at the numbers. Don't tense up, this doesn't take an economics degree. You just need to understand three things: where the money comes from, where it goes, and whether anything is left at the bottom.
Price by value, not by cost alone. Work out a rough margin: what's left when you subtract the direct costs from a sale. Build a simple 12-month forecast, not exact, just a sense of direction. The key question: how long does the cash last if sales start slowly?
How Kasvuvoima can helpWe'll work out pricing and a light forecast together, so you start with the numbers at your back. See the packages.
Part 2 · Setting up and the foundation
The official birth of the company, funding, and getting the ground rules right.
This is the moment your idea officially becomes a company. It sounds like bureaucracy, and it is a little, but in Finland the steps are clear and can be done online.
PRH and YTJ. A company is founded and registered with the Finnish Patent and Registration Office (PRH) together with the Tax Administration through the YTJ (Business Information System). At the same time you get a Y-tunnus (business ID), your company's personal identity number. Both a sole trader and a limited company can be set up electronically.
A limited company has no minimum share capital. The earlier 2,500-euro requirement was removed, so you can found an Oy with no starting capital. The limited liability still stands.
Business forms. The most common for a new entrepreneur are the toiminimi (sole trader, light, personal liability) and the osakeyhtiö / Oy (limited company, limited liability, a little more administration). The avoin yhtiö (general partnership) and kommandiittiyhtiö (limited partnership) are rarer for new digital businesses.
Setup fees and processing times change, check the current amounts straight from the source: PRH – Setting up a company and YTJ.fi.
How Kasvuvoima can helpWe guide the setup, the register choices and getting invoicing running, by email, no forced meetings. See the packages.
An official comparison of the different business forms and setup guidance is on Suomi.fi; the start-up notification goes to PRH and the Tax Administration.
Not every company needs outside money. But if you do, Finland has a surprising number of options, and many founders leave them unused simply because they don't know about them.
Starttiraha (start-up grant) is applied for before you start the business, and it's granted by the employment services. Timing matters, you generally can't get it retroactively. Amounts, duration and eligibility change: check the current amounts and terms from the source Job Market Finland (Työmarkkinatori).
Finnvera offers, for example, a start guarantee that helps you secure a bank loan. Terms and products: finnvera.fi (in English).
Business Finland funds new, innovative and internationalising business in particular. Check the current amounts and criteria: businessfinland.fi.
Estimate your YEL (entrepreneur's pension insurance) contribution and your taxes in advance with free calculators: Verotyökalut.fi
How Kasvuvoima can helpWe help you put together a fundable plan and forecast to back your applications. See services.
According to Suomi.fi the start-up grant should be applied for before registering the company; Business Finland funds research, development and innovation projects in particular, rather than the act of founding itself.
This part scares a lot of people, but it needn't. You don't need a lawyer for every decision, you need the basic building blocks in place, and the sense to know when to ask for help.
Keep customer contracts clear and in writing. If you handle people's personal data, and almost everyone does, you need a privacy policy and a clear legal basis for the processing. If you sell to consumers online, remember the rules on distance selling and the right of withdrawal.
GDPR. The EU's data protection regulation applies to anyone who handles personal data. In practice: a privacy policy, a lawful basis for processing, and a contract with the partners who process data for you. Guidance: tietosuoja.fi (Data Protection Ombudsman, in English).
Consumer protection. Consumer trade has its own rules, such as the right of withdrawal in distance selling. Never use made-up reviews or unfounded promises. More: Finnish Competition and Consumer Authority (KKV).
AI. If you use a chatbot or other AI at the customer interface, tell users openly that they're dealing with AI.
This guide is not legal advice. It's worth having important contracts reviewed by a lawyer.
How Kasvuvoima can helpYou get ready-made templates for a privacy policy and contracts, plus your GDPR settings sorted. See services.
Suomi.fi covers a company's contracts and obligations; the Data Protection Ombudsman provides official GDPR guidance.
Part 3 · Visibility and sales
How people find you, and how interest turns into deals.
A brand isn't a logo. It's the promise of what the customer gets, and the feeling they're left with. The logo and colours can come later. A clear message is needed right away.
Choose a name you're allowed to register and that has a free domain. Build a website that answers three questions in seconds: what you sell, to whom, and what the customer should do next. One clear page beats ten confusing ones.
Check that the name is free in the trade register before you get attached to it, PRH. While you're at it, reserve a suitable .fi domain.
How Kasvuvoima can helpWe build a clear, fast website that gets your point across immediately, as part of a package. See services.
Sales isn't pushing. It's helping, showing that you understand the customer's problem and know how to solve it. And above all: that you keep what you promise.
Keep leads in one place, not buried in your inbox. Reply fast, many deals are won by whoever gets there first. Make the offer clearly and always agree the next step out loud. A simple way to track follow-ups is enough at the start.
How Kasvuvoima can helpWe set up a lightweight CRM and automated follow-up so not a single lead gets lost. See the packages.
Marketing is simple but not easy: get the right people to find you, and measure what works. The rest is repetition and fine-tuning.
Start with one channel, not five. Pick the one where your customers already are, search, social media or email. Measure from day one: if you don't know what brings customers, you don't know where to put the money. Profitability decides, not the number of clicks.
How Kasvuvoima can helpWe handle one channel at a time and report results in euros, not in clicks. See services.
Suomi.fi emphasises identifying potential customers and assessing demand, competition and price level, the same applies to sales (stage 8) and marketing.
Part 4 · Running it and the finances
The everyday processes, and the part that keeps the company alive, the finances.
Once the first customers have arrived, the question changes: how do I do this again without all of it living in my head? This is where companies that grow split from the ones that burn out.
Write down the recurring steps of work, even a simple checklist will do. Automate the dull, repetitive tasks. The more that runs without you, the more freely you can focus on what genuinely needs you.
How Kasvuvoima can helpWe build automations on EU servers and documented processes that cut down manual work. See services.
Suomi.fi's section on developing the business covers management, quality and developing competence as your operations grow.
Bookkeeping isn't optional. But it isn't frightening either, once the routine is in place. The idea is simple: every euro in and out is recorded, and the tax is handled on time.
Obligation to keep accounts. Every company is required to keep accounts. For a limited company that means double-entry bookkeeping. For a sole trader the requirements are lighter, but bookkeeping is still needed.
ALV (value added tax / VAT). Most companies are liable for VAT once a certain turnover threshold is exceeded, and VAT is reported and paid regularly in OmaVero (MyTax). The standard rate, the reduced rates and the turnover threshold change, check the current amounts and rates: Vero.fi – VAT.
YEL, yrittäjän eläkevakuutus (entrepreneur's pension insurance). YEL is mandatory once your entrepreneurial activity meets the conditions set in law. It's the foundation of your pension and social security, not just a cost. The lower limit and the contributions change: check the current amounts: Vero.fi and your own pension insurance company.
Ennakkovero (prepayment tax). A company pays tax in advance based on its estimated profit. You can update the estimate in OmaVero (MyTax) if the result changes.
Tulorekisteri (Incomes Register). Wages paid are reported to the Incomes Register soon after payment. More: Incomes Register.
Check your VAT calculations quickly with a VAT calculator: Verotyökalut.fi
How Kasvuvoima can helpWe handle your monthly bookkeeping, VAT returns and invoicing for you. Read more about bookkeeping or see the packages.
According to the Tax Administration, a new company registers with PRH and the Tax Administration and may join the prepayment and VAT registers; prepayment tax is set on the basis of the estimated result.
Bookkeeping tells you what already happened. Financial steering tells you where you're heading. This is the difference between surviving and growing.
Watch the cash, it's the most common reason a new company falls over, and at the same time the easiest to prevent. Compare actuals against the plan once a month. You don't need to be a finance person to spot the warning signs in time, as long as the numbers are laid out clearly.
How Kasvuvoima can helpWe deliver a monthly financial report, clearly in euros, so you can see the situation at a glance. See the packages.
Part 5 · Closing the financial year
The year is wrapped up: the numbers are closed and the financial statements are drawn up.
At the end of the financial year, the bookkeeping is put in order ready for the financial statements. This is a checkpoint, you make sure the numbers add up before they're locked.
How Kasvuvoima can helpWe handle the year-end close methodically as part of the bookkeeping, nothing is left hanging. See services.
This is where the whole journey comes together: an idea has become a company with a full financial year behind it. The tilinpäätös (annual financial statements) tell you how it went, and they're an official obligation at the same time.
A limited company's financial statements are filed with PRH. An Oy must register its financial statements in the trade register within a set deadline after the financial year ends. Being late can lead to penalties. Current deadlines and guidance: PRH – Financial statements.
Corporate income tax is 20% of a limited company's taxable result. The general meeting confirms the financial statements, and the decisions are documented. Filing the tax return and the deadlines: Vero.fi – Businesses and corporations.
Dividend and corporate-tax calculators can be found at Verotyökalut.fi.
How Kasvuvoima can helpWe prepare the financial statements and the tax return, and handle the PRH filing, start to finish. See the packages.
A limited company registers its financial statements with PRH within the deadline, and the company's result is reported to the Tax Administration on a tax return.
