What are some limitations that could occur during onboarding in India?

When onboarding an employee in India: 

• We're unable to include Client’s name on employment agreement.
• We're required to provide the employee with health insurance.
• We're unable to change the salary CTC structure. The salary CTC structure is standardized for all Indian employees.
• Filing the Employees Provident Fund (EPF) online is now a legal requirement in India. We've put together instructions on how to do this.
