Now that you’ve purchased product keys for Microsoft 365, you can redeem them and set up a Microsoft 365 subscription for your customer. After you’ve done that, you can add users and migrate the customer’s email and data to Microsoft 365. If your client adds your partner of record (POR) number to the subscription, you are eligible for additional partner benefits and can offer delegated administration to your customer.

Redeem a Microsoft 365 product key and set up your customer’s Microsoft 365 subscription

After you have obtained a Microsoft 365 product key for your customer, you can redeem the product key and create the Microsoft 365 subscription.


  • When you set up the Microsoft 365 subscription, enter user information for the person in the customer’s organization who will be the admin for the organization. When you create the subscription, the person whose information you entered is automatically given admin rights and is assigned a Microsoft 365 license.

  • If you are the delegated admin for the customer, you are assigned admin rights when you set yourself up as the delegated admin. However, you don’t need a Microsoft 365 license to administer the customer’s subscription on their behalf.

Manage your customer’s subscription at subscription renewal time

The customer and you, if you are listed as the customer’s POR, start receiving subscription renewal notices 60 days, 30 days, 7 days, and 1 day prior to when subscriptions expire.

When your customer’s subscription is about to expire, you can help your customer renew their Microsoft 365 subscription with a product key to continue directly billing the customer. You can also choose to switch your customer to direct billing from Microsoft. If the subscription is renewed by using direct billing, the new subscription starts immediately. In this case, customers shouldn’t renew their subscription until right before it expires.

If a customer doesn’t renew their subscription in time, they can still use Microsoft 365 for 30 days after the subscription expiration date. The customer can reactivate the subscription and their data will be retained until 120 days after the expiration date. To learn more about what to expect when a subscription expires, see What happens to my data and access when my Microsoft 365 for business subscription ends?.

For more information, see Sell to and service Microsoft Cloud customers.
