What is the advantage of an annual plan versus a monthly plan?

Billing & Subscriptions

When you sign up for a Small Business or Professional annual plan, you save 20% of what that plan costs each month when compared to the month-by-month cost. That equates to yearly savings of $60 or $360 for the Small Business or Professional plans respectively. In addition, the Small Business annual plan includes Analytics & Reporting while the Small Business monthly plan does not.
