Add or reduce licenses for a prepaid subscription
Prepaid product licenses are issued to you as a 25-character alphanumeric code, called a product key. After you buy the licenses you need, you can add them to your subscription by using the following steps. You can also use a product key to extend the expiration date of your subscription.
Note
If you don't want to buy a new product key, you can always choose to add a credit card or debit card to your subscription to pay for more licenses. For more information, see What if I have a prepaid subscription?.
Add licenses to a prepaid subscription by using a product key
If you’re using the Simplified view, select Subscriptions.
If you’re using the Dashboard view, go to the Billing > Your products page.
Select the subscription to which you want to add licenses.
On the subscription details page, in the Licenses section, select Add more licenses.
In the Add more licenses pane, select Use a new and unused product key, then select Next.
Enter the product key, then select Next.
Note

Reduce licenses for a prepaid subscription by using a product key
If you used a product key to add licenses and you want to reduce the number of licenses in your subscription, you must renew your subscription with a product key that has fewer licenses.
Buy a prepaid product key that has the desired number of licenses. For example, if you currently have 50 licenses, but you only need 30, buy a prepaid product key with 30 licenses.
Reduce the total number of licenses that are currently assigned.
Extend the subscription by using the new prepaid product key.
What if I can't select the Buy licenses or Remove licenses buttons?
This table describes the reasons why the Buy licenses or Remove licenses buttons aren't available, and possible solutions.
Reason
Description
Solution
A credit check is pending.
If a credit check is pending, you can't buy or remove licenses until the credit check is complete.
Check back later to see if the credit check is complete. Credit checks typically take up to two working days to complete.
After the credit check is complete, you can select the Buy licenses and Remove licenses buttons.
You activated the subscription by using a product key.
If the subscription was bought and activated by using a 25-character product key, you see the word "Prepaid" in the Purchase channel column of the Your products page.
You see the word "Reseller" in the Purchase information section under Purchase channel on the subscription details page, and in the Purchase channel column of the Your products page.
If you bought the subscription through a Cloud Solution Provider (CSP) partner, contact your CSP partner to buy more licenses.
You have a trial subscription.
To view your trial subscriptions, select the filter button, then choose Trial.
First buy your trial subscription, then you can buy more licenses.
The product has reached end of sale
On the subscription details page, you see the following message: "This product is no longer available to buy, so some actions below are turned off."
The payment method associated with your subscription or billing profile is charged as soon as you buy more licenses for a subscription. The licenses are immediately available for you to assign to users.
If you prepaid for your subscription with a product key, you can add more licenses by using another product key, or by adding a credit card or debit card to cover the extra cost of the new licenses. If your subscription is prepaid, you can't remove licenses.
How does buying or removing licenses affect my invoice?
Licenses added in the middle of your billing period appear on your next invoice. If you pay annually, you're invoiced within a month for these changes.
If you have an MCA billing account type, you have seven days to reduce the number of licenses. If you reduce the number of licenses after that seven day period, the change appears on the first invoice you receive after the subscription renewal date.
If you have an MOSA billing account type, the previous charge for the original number of licenses is deducted on your next invoice. We add a prorated charge for the time period with the original number of licenses and add a charge for the new license count. There's also a charge for the current license count for the remainder of your billing period.
If you reduced the number of licenses for your subscription because someone left your organization, you might want to remove that user's account. To learn more, see Remove a former employee.
