For any Mutual Fund order to be successfully processed by the exchange (BSE), the payment has to be made from the bank account registered and verified with Dhan and later registered with BSE. Dhan registers those bank accounts with BSE which are chosen by you during your Mutual Fund onboarding process after verifying those on our end. 

Therefore, only those bank accounts verified / linked on Dhan for Mutual Funds can be used for making payments for MF orders. Payment made from a Bank Account that is not verified or linked, will be reversed and credited back to the bank in 7 to 10 working days and the said Mutual Fund order will get rejected.
