These days, the IPO application process is quick, easy, and paperless. After filling out the IPO application form, you can pay the fee through any of the available digital-banking options such as UPI or net banking. Upon a successful IPO application form submission, you will get an application number and a message from your bank confirming the blocking of the payment amount. Keep this information saved to track the status of your application and to ensure (in the case of an unsuccessful bid) that the amount has returned to your account.
