How to Open a French Subsidiary as a SaaS Startup

Expanding to Europe is a strategic milestone for many SaaS companies. France, with its thriving tech ecosystem, strong talent pool, and central EU location, has become one of the most attractive destinations for foreign startups. But setting up a subsidiary in France requires navigating legal, administrative, and operational challenges. This guide breaks down the entire process step by step, showing you what to expect and how to accelerate your launch.

Why France Is the Right Choice for SaaS Expansion

France has become one of Europe’s hotspots for SaaS expansion. With sixty seven million consumers and Paris as a leading startup hub, the domestic market is large and dynamic. As part of the EU single market, France also gives immediate access to more than four hundred million consumers without trade barriers. The country offers a deep talent pool of engineers, product managers, and sales professionals, many of whom are bilingual. Government support is strong, with powerful incentives such as the Crédit d’Impôt Recherche and the Jeune Entreprise Innovante status. Fintech and SaaS adoption are growing rapidly, with global players like Stripe, Snowflake, and Datadog scaling in Paris.

Choosing the Right Legal Structure

Foreign startups typically consider three structures: the branch, the SARL, and the SAS. The branch is a simple extension of the parent company, quick to set up but offering limited credibility. The SARL is more rigid and suits traditional SMEs rather than high-growth tech. The SAS, or Société par Actions Simplifiée, is the clear choice for SaaS companies. It offers flexible governance, limited liability, investor appeal, and can be entirely foreign-owned. For more detail, see our guide on why the SAS is the best structure for startups.

Drafting the Bylaws

Bylaws define how the French entity will operate. They must be drafted in French and include the company name, the registered office, share capital, governance rules, management roles, voting rights, and business activity. These documents are filed with the Commercial Court and form the constitution of the company. Working with local legal support avoids errors that could delay incorporation.

Depositing the Share Capital

Creating a SAS requires a capital deposit in a French bank or notary’s escrow account. The minimum is one euro, but most SaaS founders deposit between one thousand and ten thousand euros to demonstrate credibility. Proof of deposit is mandatory to finalize registration. Opening a bank account is often the most complex step for foreign founders because French banks require in-person presence and strict KYC. Fintechs such as Qonto or Shine are faster alternatives for the initial deposit, but traditional banks are usually needed for long-term fundraising and financing.

Legal Notice and Registration

French law requires the publication of a legal notice in a Journal d’Annonces Légales. This announcement confirms incorporation by stating the company name, legal form, address, share capital, and management details. The cost is around one hundred fifty euros. Once the bylaws, capital deposit, and legal notice are complete, the file is submitted to the Commercial Court. After review, the Greffe issues the K-Bis, the official ID of the company.

Taxes and Social Contributions

With the K-Bis, the company can register for VAT, open a permanent business bank account, and register with URSSAF to handle payroll and social contributions. Employer contributions add forty to forty five percent to gross salaries. A contract at fifty thousand euros gross per year translates into a real employer cost of around seventy thousand euros. For a breakdown of how this impacts hiring budgets, see our article on payroll and costs in France.

Hiring Your First Employees

To build a local team, SaaS founders must comply with French labor law. The CDI, or permanent contract, is the default and signals stability to candidates. Employees benefit from paid vacation, supplementary health insurance, retirement contributions, and transport subsidies. Outsourcing payroll is highly recommended at the start to avoid compliance mistakes. Our article on hiring in France details best practices for structuring contracts and benefits.

Launching Operations

Once registered, the French entity can sign contracts with local clients, issue invoices in euros, and hire a country manager or sales team. Many SaaS startups begin with coworking space before moving into offices. A typical incorporation timeline is four to eight weeks, with one week for drafting bylaws, up to four weeks for capital deposit, one week for publication, and one to two weeks for court registration. Costs usually range between two and five thousand euros including legal drafting, publication, and domiciliation.

Common Pitfalls

Foreign startups often underestimate banking delays, which can extend incorporation by months. Choosing the wrong entity type reduces credibility with clients. Payroll mistakes are costly and compliance is strict. Finally, a purely virtual presence without local staff limits traction, as French clients prefer working with companies that have a real presence in the country.
