My investment is done, when will the units get allocated?

Well, this entirely depends on the way you choose to make a particular investment. 

1. Net Banking/UPI Payment (through OTP payments): If you have transferred money via net banking before 1 pm on a working day, then the amount will be invested on the same day and units will be allotted to you within 2-3 working days. If you have transferred the money post 1 pm, then the same will be invested on the next day. We will clearly show you the date of your investment to keep you informed on time. 
2. Net Banking/UPI Payment (through payment gateway): If you have transferred money via net banking the same will be invested on the next day. We will clearly show you the date of your investment to keep you informed on time. 
3. Bank Mandate-based Automated Transfer: If you are opting for this option then you can expect the units to be allotted to you within 2-3 working days from the scheduled date of your investment. 

Apart from the Stock market declared holidays, Saturday and Sunday are non-working days and payment received on such days will always be deposited on the next working day. You can find the list of holidays here: https://www.nseindia.com/global/content./market

Then it further takes around 2-4 working days to get reflected in your portfolio. So overall, it takes around 5 working days after making the investment for the units to show in your portfolio.
