No, it is not compulsory.
However it makes it convenient. You can setup an SIP to auto debit your bank account periodically, or just pay-as-you-go. The three models are:
- Auto Debit using eMandate. No need for Net Banking! Register the mandate via email and OTP on your Aadhaar-BankAccount-Phone combo.
- Auto Debit using iSIP mandate. Register the iSIP on your Bank’s net banking website.
- Just Pay as You Go. Pay via link emailed to you each time.
