Understand billing concepts

Before you view your invoice, it's helpful to understand a few key billing concepts.

Invoice balance vs. order balance

Invoice balance is the amount shown on your invoice, and is only the amount due for that particular billing period. Your total order balance is the sum of all unpaid invoices. You can view your order balance in the Billing section of the Office 365 admin center.

Billing frequency vs. invoice frequency

Billing frequency means how often you are billed. Subscriptions are billed either monthly or annually, depending on what option you selected during the subscription purchase. Invoice frequency means how often you receive an invoice. If you chose annual billing, you'll only receive one invoice per year, unless activity for your subscription requires a charge or a credit.

If you have more than one order, you'll receive an invoice for each order.
