The Act does not make an application “deemed approved” when a time limit is missed. What it gives is a fixed time limit for each service, alerts to officers before it runs out, a single query round and a grievance route. Several renewals, such as the factory licence, consent to operate and the contractor licence, are automatic.<\/p>\n

How to apply, step by step<\/h2>\n
    \n
  1. Open silpasathi.wb.gov.in, choose Apply Online and create an account; verify your email and mobile by OTP.<\/li>\n
  2. Log in by OTP and go to Self Assisted Service, then Add New Unit, with the business name, constitution, PAN and address.<\/li>\n
  3. Choose the service you need and click Create CAF. The portal generates a CAF ID; one CAF can cover approvals of more than one department.<\/li>\n
  4. Fill the form and upload the documents in the checklist shown for that service. Some services need a digital signature.<\/li>\n
  5. Submit the declaration and pay the fee online through GRIPS.<\/li>\n
  6. Track the application on the dashboard; SMS and email alerts follow each step, including any query from the department.<\/li>\n
  7. Download the certificate from the portal once approved.<\/li>\n<\/ol>\n
