Sign in to the admin center and go to Billing > Subscriptions > Add-ons.

Why don't I see the option to buy add-ons?
In a few situations, you won't see the option to buy Skype for Business add-ons in the Microsoft 365 admin center.
You purchased Microsoft 365 Business Standard through GoDaddy. In this case, you can't buy Skype for Business add-ons. You need to switch to the E3 plan (which GoDaddy doesn't sell), and then you can buy them. Contact support for business products - Admin Help.
You have a monthly commitment instead of an annual commitment. In some cases, customers who have a monthly commitment can't buy the add-ons (this is different from the payment method, which can be monthly). This is a known issue that we are fixing. Contact support for business products - Admin Help.
