Process of Company Formation in Singapore: Company Registration in Singapore will start with the approval of the company name and end with the issuance of the Company Formation Certificate . The business name must be approved by ACRA and this usually happens within the hour. The name must be unique, meaningful and decent. Once your company name is approved, you can submit the form and supporting document via the Bizfile portal. The company formation process is usually completed within 1 to 3 days if all documents are in order. Once registration has taken place, the ACRA Business Registration Office will send a notification via email. The email includes your registration number and is treated as your official certificate of incorporation. You can start your business immediately after receiving the certificate of incorporation.
