Billing for your program will typically be done on a monthly basis (can be quarterly, semiannual, or even billed up front for a budgeted program) with invoices reaching your inbox typically between the 4th and 6th business day of the following month. This delay is due to the fact that reporting and analysis cannot be done until the first day of the next month.
Your invoice will split the editorial Pay-Per-Click program and the sponsored Pay-Per-Click program into separate line items. If your sponsored bids vary on a per-item basis, your invoice will contain an aggregate of the clicks for the month instead of a line-by-line breakdown.
If requested, a detailed click report can be sent along with the invoice, although this is not done by default.
