Guests pay in advance and utility bills arrive in arrears
You got paid in advance on the 6th March for the month, the utility bills generated by this stay don't come in until April, so why haven't you saved some of the payout to cover the bills.
Your guests April payout when its released is to pay for bills generated by the guests during their stay in April and you don't get this utility bill until May, part of the payout shoud be saved to pay this bill.
You appear to expect the current guests payment to cover the cost of utility bills for the previous month, this could leave you with no money to pay bills if you have a drop in bookings.
