Understand your invoice for Office 365 for business
Each month you'll receive an email that tells you that your new billing statement is available in the admin center. Learn how to find and view your bill or invoice.
Your invoice contains two pages. Page 1 is the invoice summary, and contains general information about the invoice, order, amount due, how to make a payment, and how to contact support.
Page 2 contains details about the billing activity for each subscription.
For descriptions of the fields and terms included in your invoice, see the Invoice Field Glossary later in this article.
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 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 chose 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.
