Why is there a delay of one day in adding money to Groww Balance?

There is a gap of one day between initiating a deposit via NACH mandate and actually receiving the money in your Groww balance. 
We will check your Groww balance every day at 5 pm and in case it is lower than the threshold set by you, we will initiate a deposit. The amount will be credited to your Groww balance the next day by 9 pm.
