1. Quick answer: how to choose

If you want the short version, here it is:

Light entrepreneurship is usually the better choice when you want to start quickly, invoice one-off assignments and keep the admin as light as possible. It is a good way to test demand, earn side income or work with your first clients without setting up your own business.

A sole trader business is usually better when your work is regular, your expenses are significant, you want your own Finnish Business ID or your clients expect to buy directly from your business. A sole trader setup gives you more control, but it also gives you more responsibility.

In practice, the decision often looks like this:

SituationOften the better choiceWhy
Your first gigs, and you do not yet know whether the work will continueLight entrepreneurshipYou can start quickly and keep the admin light
Side work alongside employment or studiesLight entrepreneurshipYou do not need to build your own business administration straight away
Regular invoicing every monthSole trader or light entrepreneurshipYour own accounting and tax planning may start to make sense
Many tools, software subscriptions or other expensesSole traderExpense and VAT handling is more flexible
You want to protect your business name and show clients your own Business IDSole traderThe client buys directly from your business
You sell physical products or build an online storeSole traderStock, purchases and VAT are easier to manage through your own business
You do occasional service gigs for consumers or small companiesLight entrepreneurshipThe invoicing service handles invoicing and payment processing for you

The key point is that the choice is not permanent. Many people start as light entrepreneurs, find their first clients and register as a sole trader only later, once the work becomes regular.

In this article, light entrepreneurship means working through an invoicing service without your own Finnish Business ID. Some services also use the term for models where you do have a Business ID. In that case, the responsibilities are already much closer to a sole trader business.

2. What is light entrepreneurship?

Light entrepreneurship is not an official Finnish company form in the same way as a private trader business or a limited liability company. It is a practical term for working like an entrepreneur through an invoicing service.

When you work as a light entrepreneur without your own Business ID:

  • you agree on the work directly with the client
  • you do the work with your own skills
  • you send the invoice through an invoicing service
  • the invoicing service invoices the client
  • you are paid according to the service model, often as salary or work compensation
  • the service handles withholding tax, reporting and the technical side of invoicing

Light entrepreneurship works best for service work. Typical examples include photography, content creation, design, consulting, event work, cleaning, renovation work, training, massage therapy or other work where you mainly sell your own time and expertise.

It is less suitable if you want to buy and sell goods, keep stock, run a larger online store or build a company with employees, partners and many contracts.

The biggest benefit is simplicity. You do not immediately need to think about accounting, VAT returns, a business tax return or Trade Register filings. You can focus on whether clients exist and what they are willing to pay.

3. What is a sole trader in Finland?

In Finland, a sole trader is a private trader, often called toiminimi in Finnish. You have your own Business ID, invoice through your own business and take care of the obligations that come with running that business.

A sole trader business is not a separate legal person in the same way as a limited liability company. Legally, the business is closely tied to you as an individual. That makes it a light and fast company form, but it also means that you are personally responsible for contracts, debts and mistakes.

A sole trader normally handles, either alone or with an accountant:

  • invoicing
  • accounting
  • tax prepayments
  • VAT, if registered for VAT
  • the business tax return
  • possible YEL insurance
  • contracts, insurance and client risk

A sole trader setup is a good choice when you want to run your own business on a more permanent basis. It suits solo entrepreneurs, freelancers, specialists, craftspeople, online sellers and service providers who invoice regularly and want to operate under their own name or brand.

4. Light entrepreneurship vs sole trader business

TopicLight entrepreneurship without your own Business IDSole trader
StartingYou register with an invoicing serviceYou request a Business ID and register where required
Business IDNo Business ID of your ownYour own Business ID
InvoicingThe invoicing service sends the invoiceYou send invoices yourself or with software
AccountingThe invoicing service handles its sideYou are responsible for bookkeeping
TaxationIncome is handled according to the service model, often as wages or work compensationBusiness profit is taxed in your personal taxation
VATThe invoicing service handles VAT on the invoiceYou register for VAT if the threshold is exceeded or you register voluntarily
ExpensesYour own deductions are more limited and depend on the situationBusiness expenses are deducted in bookkeeping
YELYEL may apply if the conditions are metYEL may apply if the conditions are met
LiabilityYou are responsible for your own work, but the service handles the invoicing processYou are responsible for your business contracts and obligations
Professional impressionWorks for many clients, especially service gigsYour own Business ID can matter to larger clients
GrowthGood for testing and side workBetter for long-term business activity

Put simply: light entrepreneurship gives you simplicity; a sole trader business gives you control. Neither is automatically better. The better option depends on where your work is today.

5. Start-up costs and administration

Starting as a light entrepreneur is usually quick. You register with an invoicing service, fill in the required details and can send an invoice once the work is done and the client accepts the invoice.

With light entrepreneurship, you usually pay the service fee only when you invoice. This is clear for beginners, because you may not have fixed monthly costs when you are not invoicing. The service fee reduces the amount you take home, but in return you save time and avoid having to learn every administrative detail at the start.

With a sole trader business, the cost structure is different. In some situations, you can request a Business ID through the Finnish Tax Administration and sign up for the relevant Tax Administration registers at the same time. If you register a private trader business in the Trade Register, the processing fee in 2026 is EUR 75. Not every private trader has to register with the Trade Register, but registration may make sense if you want to protect your business name and look more established to clients.

Ongoing costs for a sole trader can include:

  • an accountant or accounting software
  • invoicing software
  • a business bank account, if you want to keep money clearly separate
  • insurance
  • YEL contributions, if the YEL conditions are met
  • software, tools, marketing and website costs

If you invoice only a few hundred euros now and then, these costs can feel heavy. If you invoice thousands of euros every month, your own sole trader business may become more sensible both financially and practically.

6. Taxation and VAT in 2026

Taxation is one of the biggest differences between light entrepreneurship and operating as a sole trader.

As a light entrepreneur without your own Business ID, you usually do not file your own business tax return. The invoicing service pays you according to its operating model and handles the related reporting. Your job is to keep your tax card up to date and check that the income appears correctly in your personal tax information.

As a sole trader, your business profit is part of your personal taxation. You pay tax prepayments based on your estimated profit and file a business tax return. If your profit changes during the year, you usually need to adjust your prepayments so that you do not pay too much or too little.

VAT for light entrepreneurs

As a light entrepreneur without your own Business ID, you are not personally in the VAT register. The invoicing service adds VAT to the invoice when the work is subject to VAT and handles the VAT in its own system.

This is easy, but it has a practical consequence: you cannot deduct VAT included in your own purchases in the same way as a VAT-registered business can. If you buy a lot of tools, software subscriptions or materials, a sole trader setup may become more attractive.

VAT for sole traders

In 2026, a sole trader must follow the VAT threshold for small-scale business activity. A business does not need to register for VAT if its turnover in both the current and the preceding calendar year is no more than EUR 20,000. If the threshold is exceeded, VAT liability starts from the date the threshold is exceeded.

This is where many old articles are wrong. The threshold is no longer EUR 15,000. It rose to EUR 20,000 from the beginning of 2025. At the same time, the VAT lower-limit relief was abolished. Previously, a small VAT-registered business could receive part of its remitted VAT back as lower-limit relief, but that relief no longer exists.

A sole trader can also register for VAT voluntarily even if turnover stays below the threshold. This can make sense if your clients are companies and you have a lot of business purchases that include VAT. If your clients are consumers, VAT can make the final price higher for them, so you should calculate the impact before deciding.

7. Expenses, deductions and purchases

If your business expenses are small, light entrepreneurship is often enough. For example, a writer, trainer, photographer or consultant may be able to start with a laptop, a phone and a few software tools.

If you need to make a lot of purchases, a sole trader business may be better. As a sole trader, you can enter business expenses in your bookkeeping and deduct them from your business profit. If you are VAT-registered, you can usually deduct VAT included in business purchases from VAT on your sales.

A sole trader setup may be more sensible if you have:

  • expensive tools or equipment
  • recurring software costs
  • marketing and advertising costs
  • workspace or business premises costs
  • subcontractors
  • travel expenses
  • stock or material purchases
  • a need to clearly separate business money from personal money

Light entrepreneurs can also deduct income-generating expenses on their personal tax return in certain situations. In practice, however, deductions are not as flexible as in your own business bookkeeping. That is why a sole trader business often starts to look attractive when expenses are no longer occasional, but a real part of the business model.

8. YEL, unemployment security and social security

YEL can apply to both sole traders and light entrepreneurs if the YEL conditions are met. Having or not having your own Business ID is not the only deciding factor.

In 2026, the lower limit for YEL income is EUR 9,423.09 per year. The minimum YEL income required for unemployment security as a self-employed person is EUR 15,481 per year. The YEL contribution rate in 2026 is 24.40% of confirmed YEL income, and a first-time self-employed person receives a 22% discount on YEL contributions for 48 months.

YEL income is not the same as your invoicing or profit. It should describe the value of your own work in the business: what you would need to pay an outside worker to do the same work. This matters because YEL affects not only pension accrual, but also sickness allowance, parental allowances and unemployment security for the self-employed.

Unemployment security is something to check carefully. If you start entrepreneurial activity while unemployed, you may be able to receive unemployment benefit for the first four months before the authorities assess whether the activity is full-time or part-time. The assessment is made after four months. Your job search must still remain valid, and you must be ready to accept full-time work.

If you are unemployed or receive benefits, check your situation before sending your first invoice. This applies to both light entrepreneurship and a sole trader business. Small side income may be possible, but decisions are made based on your personal situation.

9. Liability, risks and the client’s point of view

Light entrepreneurship often feels safer because the invoicing service handles administrative matters for you. It does not remove all responsibility. You are still responsible for doing the work as agreed, delivering what the client was promised and using sensible contract terms.

With a sole trader business, responsibility is more direct. You make contracts through your own business and are personally responsible for them. If an invoice is unpaid, the client complains about quality or the project expands beyond the original scope, the matter is yours to handle. That is why contracts, payment terms, liability insurance and clear scope limits are important.

From the client’s point of view, both models can work well. A small client may not care whether the invoice comes from an invoicing service or your sole trader business, as long as the invoice is clear and the work is done well. A larger company may require your own Business ID, prepayment register status, e-invoicing, liability insurance or specific contract terms. In those situations, a sole trader setup may be easier in practice.

Some industries also require permits and insurance. For example, healthcare, taxi services, alcohol-related business, construction, electrical work and certain safety-related tasks may require permits, qualifications or special insurance. If the work is regulated or the risk of damage is high, do not choose the model based only on convenience.

10. When is light entrepreneurship the better choice?

Light entrepreneurship is often the best choice when you want to start without committing to a full business setup. It is especially suitable when the most important thing is to invoice quickly and see how demand develops.

Choose light entrepreneurship if:

  1. You are doing your first invoiced assignments.
  2. You do not yet know whether the work will continue.
  3. You invoice occasionally or seasonally.
  4. You want to focus on the work, not administration.
  5. Your expenses are small.
  6. You sell your own expertise, not stock products.
  7. You have paid employment, studies or another main source of income.
  8. You want to test pricing and client acquisition before registering as a sole trader.

Light entrepreneurship is a good way to get real information. Are there clients? Do they pay on time? Is the work something you want to do more of? Is your pricing right? You cannot answer these questions with a plan alone. The only way to answer them is by doing the work.

Bisse.fi is well suited to this stage, because you can invoice without your own company and handle payment through the service. When the work grows, you can decide without rushing whether a sole trader business is the next sensible step.

11. When is a sole trader business the better choice?

A sole trader business is often better when the work is no longer just a test and is turning into regular business. Your own Business ID brings administration, but it also brings credibility, freedom and better tools for planning.

Choose a sole trader business if:

  1. You invoice regularly every month.
  2. You already have recurring clients.
  3. You want to build your own business name and brand.
  4. Your clients require your own Business ID or prepayment register status.
  5. You have significant purchases or recurring expenses.
  6. You want to decide on accounting, invoicing and contracts yourself.
  7. You sell goods, materials or online store products.
  8. You plan to seek financing, sign larger contracts or grow the business.

A sole trader business is not as administratively heavy as a limited company, but it does require routine. Once tax prepayments, bookkeeping, VAT, invoicing and contracts are under control, it can be a very efficient way to work as a solo entrepreneur.

If the business grows significantly, a limited liability company may become relevant later. For many people, however, a sole trader business is a useful middle step between light entrepreneurship and a company built for growth.

12. Practical examples

A student creates social media visuals for two clients

Invoicing is occasional, expenses are small and the work may remain side income. Light entrepreneurship is usually the most sensible place to start. If clients start coming in every month and more money goes into software, camera gear or marketing, a sole trader business can be considered later.

An IT consultant works on an ongoing project for a business client

If monthly invoicing is several thousand euros and the client wants to contract directly with a business, a sole trader setup may be better. Your own Business ID, contracts, liability insurance and VAT handling are often natural in this situation.

A hairdresser or massage therapist tests client acquisition part-time

If the work involves a few clients per month, light entrepreneurship may be enough at first. If the work becomes regular and you need premises, equipment, a booking system and many supplies, a sole trader business can quickly become more practical.

A craftsperson plans an online store

If you sell physical products, buy materials, keep stock and price products with VAT in mind, a sole trader business is usually clearer. Light entrepreneurship is better suited to invoicing services than running product sales.

An unemployed jobseeker gets a first assignment

Before invoicing, contact your local employment services or your unemployment fund. Light entrepreneurship can be a good way to test work, but unemployment security, start-up grant questions and the assessment of full-time or part-time activity must be checked based on your own situation.

13. Decision checklist

Go through these questions before deciding:

  1. Do you invoice only occasionally or every month?
  2. Is your activity still a test or already a clear business?
  3. Do you sell your own work, or also goods and materials?
  4. How many purchases and recurring expenses do you have?
  5. Does your client need your own Business ID?
  6. Is the VAT threshold of EUR 20,000 exceeded now or likely to be exceeded soon?
  7. Could YEL become mandatory?
  8. Do you receive unemployment benefit, student aid or another benefit?
  9. Do you need liability insurance or industry-specific permits?
  10. Do you want to spend time on accounting and tax matters?

If most answers point to testing, occasional invoicing and small expenses, light entrepreneurship is often more sensible. If the answers point to regular invoicing, larger expenses, business clients and your own brand, a sole trader business becomes the stronger option.

14. Summary

Light entrepreneurship and a sole trader business solve different problems.

Light entrepreneurship solves the starting problem. It makes the first invoice easy, reduces administration and lets you test your skills in the market without setting up your own business. It is often the best option when invoicing is occasional, expenses are small and you want to get started quickly.

A sole trader business solves the long-term operating problem. It gives you your own Business ID, more control, better expense handling and a clearer business identity. It suits you better when the work is regular and you want to build your own business for the long term.

A good rule of thumb is this: start light if you are not sure yet. Move to a sole trader business when the work deserves its own structure.
