To pay with monthly invoicing, you will need to have a live insertion order set up.

The statement is True because, to pay with monthly invoicing in Microsoft Advertising, you must have a live insertion order set up. An insertion order is a formal agreement that outlines the terms of the campaign, including the budget, targeting, and billing details. It is required to enable monthly invoicing as a payment method, which allows advertisers to be billed at the end of each month for the campaigns they run. This process ensures that billing is handled correctly and in accordance with the agreed-upon terms in the insertion order. Without a live insertion order, monthly invoicing cannot be used, as it ensures that both the advertiser and Microsoft Advertising are aligned on the financial aspects of the campaign. Therefore, setting up a live insertion order is a necessary step to take advantage of monthly invoicing.
