E-NACH or an e-Mandate is a payment method that allow anyone with a bank account to easily automate recurring payments without using any offline process. You can set up FLEXI-SIPs once youre-mandate is approved.

They are an alternative to paper mandates.

You can authenticate an e-mandate through an Aadhaar-based authentication.
Your bank account will need to be linked with your Aadhaar.

The general Turnaround Time (TAT) for e-mandate approval is 5- 7 business days.

Please note that e-mandates have a fixed limit of up to Rs 1,00,000.  In case you want to increase this limit, please use the paper mandate instead.
