Decision framework

Start with a sole trader if: you are testing an idea, your expected profit is below €50,000, you have minimal liability risk, and you want maximum simplicity.

Choose a VOF if: you start with 2+ co-founders, your combined profit is below €80,000, and liability risk is low.

Start with a BV if: your profit exceeds €70,000, you have significant liability risk, you plan to hire staff or you want to raise investment.

Start with BV + holding if: your profit is above €80,000, you plan to build long-term wealth, you may want to sell the business one day, or you plan to own multiple companies.
