Recurring billing involves pre-setting amount to bill the client on a set frequency such as weekly, biweekly, monthly, quarterly, etc. The billed amount is the same regardless of the hours expended. Web Suite allows you to include the expenses in the recurring bill or to add them separately to the invoice (in addition to the recurring amount).
Frequency of billing for a project starts from the date of the invoice.
When you select a Recurring contract type for a project, Web Suite generates the billing record as per the frequency set in the Project screen. It does not automatically create an invoice; however, it does remind you via Dashboard-Reminders panel that bills need to be processed. If billing does not take place, Web Suite generates a recurring billing record for each billing period in Billing Review.
Preferred invoice layouts for recurring bills vary widely. Some prefer a detailed list of time and expenses to show the amount of work done, while others prefer a fixed (single fee) invoice with occasional memos. See Processing Recurring Invoices for more information.
