The fee for new member based on the days remaining in the current billing period will be charged on your credit card in addition to your regular payments. Let's say, if a new member is added on the 10th day of billing period and there are 20 days left until the next billing period,under the following conditions: Your contract = Standard Plan, Fee per members = $8.00 per month per active user; Daily fee of the new member will be "$8.00 divided by 30 days" and the total cost of the new member will be $5.33 as 20 times of daily fee. It will be charged on the registered credit card for the space which the new member is added.
