This feature would be a great way for our Monzo customers to segregate their monthly bills to one account. How the account could work:
The account would act like a pot.
The pot has a sort code and account number (enabling direct debits/standing orders).
The pot would not have a physical card
Customers can transfer in (and out) any amount of money (BAU)
Software integration would build analytics and inform customers how would is needed to be transferred into the pot to ensure direct debits are paid. As direct debits are visible a day before - Monzo could send a notification if there are insufficient funds - allowing customers to transfer funds in before the debit.
