TL;DR
Forming a SASU takes anywhere from a few days to a few weeks. Three clocks run one after the other: preparing the file (you, the bank and the legal notice publication), filing with the guichet unique (single online filing portal, within 24 business hours of receiving the complete file with the Rapide plan), then approval by the greffe (commercial court registry), which does not depend on any provider.
The steps and who controls them
| Step | Who | Typical duration |
|---|---|---|
| Questionnaire and generation of the articles of association | You | 5 minutes |
| Opening the account and depositing the capital | You and the bank | Varies by bank (identity checks) |
| Signing the articles of association | You | A few minutes (electronic signature) |
| Publishing the legal notice | Authorised publication | Usually within 24 to 48h |
| Filing with the guichet unique | LegalRapide | Within 24 business hours of a complete file (Rapide plan) |
| Approval and registration | Greffe | Varies by greffe and time of year |
| Correction if the greffe asks for the file to be put in order | You and LegalRapide | Documents to provide within 15 working days |
What most often causes delays
- An illegible or expired ID document.
- An inconsistency between the articles of association, the legal notice and the form (address, share capital, president's name).
- Missing proof of registered office address.
- A missing certificate of deposit of funds.
