Sending the customer’s bill out may depend on some of the items such as the date which the customer has become Web Design Company’s subscriber. Preparing the services for a month is a billing period that starts from the first day of the month and will end to the last day on it based on the calendar. This period will repeat from the first day of next month until when the company receives a “cancel request” from the customer (according to the clause of canceling in the document). The first period starts when Web Design Company received the order form for the customer, if it receives the order form in the first day or other days of beginning the month, it’s possible to compute the cost of that month based on the remaining days of that. Web Design Company can changes the billing period according to its discretion without the customer’s awareness, as maybe some of the more or fewer bills going to send out for the customer. The time period that the customer’s account is suspended also will compute in the billing period.
