I am inclined to agree with your accountant. This type of utility is a "Service" you are paying for on a monthly or annual basis. At best, if you have paid an annual subscription up front, depending on the amount paid in relation to the size of your business or expenses, you could classify it as a "Pre-paid" expenses and then write it down each month until it is totally expensed. But it is perhaps more practical to treat the whole thing as a one time expense as it occurs.
