Yes! You can add additional payments over the course of the month for any amount you'd like up to the amount you were invoiced.
For example, if your bill payment is $1,000 each month, you could make two payments of $500 each. There are no extra fees or expenses associated with splitting your payments, but payment processing fees may apply to each transaction.
Please note that if your community has a late fee policy then you will need to pay the full invoice amount before that date to avoid that late or enroll in Pay Over Time to choose a later due date.
