Changing or closing a company follows a strict legal path: a new KBIS about 30 days after a modification; closure in two steps — dissolution and its KBIS, then liquidation & RCS deregistration with the radiation KBIS ~30 days later. For freelancers: URSSAF / Impôts debt checks and final filings.

Who it's for

  • Companies changing address, director or name
  • Companies ceasing activity
