If you are a Microsoft Office 365 for professionals and small businesses administrator, you can increase or reduce the number of licenses or the amount of storage space that you bought originally. The cost for more or fewer licenses or for more or less storage is prorated for the rest of the subscription term. You have to use the same payment method that you used when you bought the original licenses. To change the number of licenses or the amount of storage space for a subscription, follow these steps.
On the Admin page, in the left pane, under Subscriptions, click Manage.
On the Billing and subscription management page, click a subscription name.
On the Subscription details page, click Change quantity.
Follow the steps in the Change quantity wizard to complete your order.
If you paid for the subscription by credit card, any new licenses or storage space that you order will be available immediately after you receive an order confirmation. If you’re invoiced for subscription payments, you may be asked to complete a credit check. In this scenario, the new licenses will not be available until the credit check is complete.
