Which business forms can offer software development services?
Tyoon can be used by service providers operating under different business forms. Each service provider is responsible for invoicing, taxes, insurance, business registrations and any permit and qualification requirements.
Freelancer without a registered company
Some software developers initially work without a registered company, for example alongside studies or on a grant. Even without a registered company, you must still declare your income to the tax authority and handle other statutory obligations appropriately.
This may suit you, for example, if:
- you are only doing individual small assignments so far
- you are not yet sure whether to start a company
- you work on a grant or other form of income
Light entrepreneur (kevytyrittäjä)
Light entrepreneurship can suit a developer who wants to do individual software development assignments and invoice their work through an invoicing service. Always check your invoicing service terms and make sure the service you plan to offer can be invoiced through it.
This option may suit you, for example, when:
- you work on the side
- you only take a few projects per month
- you want to try offering services
- you offer services personally without employees
Sole trader (Tmi)
A sole trader can suit an independent software developer who wants to build a longer-term client base. Tyoon can help you find new clients and supplement your current project calendar.
A sole trader service provider can, for example:
- find regular private and business clients
- offer development packages or hourly-billed work
- make agreements with business clients
- invoice customers directly
- build their own portfolio and business profile
Limited company (Oy)
A software company or digital agency operating as a limited company can use Tyoon to find new clients and requests. The company can decide itself which tasks to send offers for.
The service may suit a company that has:
- several developers or freelancers
- an established development process and tools
- business clients
- the ability to carry out larger software projects
- capacity for working on several projects at once
General or limited partnership
A general partnership or limited partnership can also register on Tyoon as a service provider. This may suit, for example, a software company or digital agency run jointly by several developers.
How to find software development projects on Tyoon
1. Create a service provider profile
Register as a service provider and describe what software development you offer.
Add to your profile at least:
- your area of expertise, for example web development, mobile apps or backend development
- the programming languages and technologies you use
- your experience and references
- your availability
- languages you use
- your business form
2. Browse open tasks
Customers describe in the task the service they need, its scope, schedule and possible budget. Read the task description carefully and ask for more information if needed before confirming the price.
3. Send the customer an offer
Your offer should mention:
A good offer should state:
- proposed price
- hourly, daily or fixed price
- when you can start and the estimated completion time
- what is included in the implementation
- which technologies and tools you use
- possible ongoing maintenance costs
4. Agree on source code, usage rights and other details
When the customer accepts your offer, agree in writing on the scope of work, price, schedule, and who owns the source code and usage rights to the finished software.
How is the service price formed?
The price of software development may be affected by, for example:
- • the scope and complexity of the project
- • technologies and programming languages used
- • estimated amount of work in hours or days
- • schedule and urgency
- • maintenance required after launch
- • number of integrations
- • scope of testing
- • usage rights and ownership of the source code
Hourly billing can suit projects whose scope is hard to estimate in advance, such as maintenance or ongoing development. Daily pricing can suit longer, continuous assignments where you work on the customer’s project for a set period of time. A fixed price can suit clearly defined projects whose scope and outcome are precisely specified in advance. Phased pricing, where the project is divided into parts and billed stage by stage, can suit larger projects and helps manage risk for both parties. A monthly maintenance agreement (retainer) can suit ongoing support and small further development tasks after the finished software has launched. State clearly in your offer what the chosen pricing model covers and how any additional work or change requests will be priced.
What does using Tyoon cost?
Registering on Tyoon is free and there is no monthly fee.
You can browse open tasks and decide yourself which ones to send an offer for.
Tyoon charges the service provider a fee only on completed and finished tasks according to the current terms of use. If the customer does not choose your offer, no fee is charged.
Tips for a strong service provider profile
A good profile helps the customer assess your skills and previous projects.
Add to your profile:
- • a clear description of the services you offer

- • the programming languages and technologies you use
- • a portfolio or links to previous projects
- • your experience and education
- • company details
