Compare French SAS, SARL, EURL and SASU through a founder lens: pay, dividends, co-founders, fundraising, social protection and governance.
Estimate the indicative cost of a founder net salary under each structure.
Compare simplified dividend treatment and retained profit capacity.
Identify when co-founders, governance or fundraising should drive the decision.
The choice is not only about social charges. A business with co-founders, planned fundraising, recurring dividends or a strong need for social protection needs a different setup from a solo consulting activity. The simulator gives a first model, then the legal and tax choices need to be reviewed.
SAS and SASU are flexible and widely understood by investors. Founder payroll costs can be higher, but the structure is often better suited to capital changes and growth.
SARL and EURL can fit owner-managed businesses looking for a more standardised framework and lower indicative social cost on manager pay. Governance and future capital changes need to be anticipated.
The right decision connects tax, payroll, cash flow, shareholders, legal documents and exit horizon. Coherence matters more than the headline number.
A useful simulation must be reviewed alongside articles of association, shareholding, financial forecasts and founder income needs.
We treat the structure choice as a management decision: founder income, social protection, corporate tax, VAT, shareholders and financing path. SAS can be excellent for a startup, but excessive for a stable solo business; EURL can be rational, but too rigid if capital must change.
The wrong structure rarely costs only in charges. It can block an investment round, make shareholder exits harder, create poorly calibrated pay or leave too little cash for tax and contributions.
SAS is often more flexible for investors, but the decision depends on share rights, governance and the investment plan. The simulator does not replace a legal review.
The majority manager regime can show a lower indicative social cost on pay, but protection, dividends, cash flow and personal goals must also be included.
EURL can suit regular income and a structured owner-managed setup. SASU is often chosen when investor-readiness or future capital flexibility matters.
Dividends matter, but they should not be the only criterion. They require distributable profit, available cash and a coherent investment policy.
Payroll, social charges, corporate tax, VAT and founder-company flows need to be checked against your actual situation before incorporation.

We can model founder pay, dividends, shareholding and growth plans before you commit to the wrong structure.
