Easiest way to identify the Enterprise Administrator for Azure

Microsoft’s documented workflow does not provide a tenant-wide Marketplace purchaser directory; customers must identify the billing agreement and inspect role assignments at the relevant billing-account and subscription scopes.

A user without access to the applicable billing scope generally cannot enumerate its billing administrators. Billing permissions are separate from Microsoft Entra directory roles and subscription-level Azure RBAC roles.

1. Identify the customer’s billing agreement

In the Azure portal:

1. Open Cost Management + Billing.
2. Select Settings > Properties.
3. Note whether the billing account type is:
   • Enterprise Agreement (EA)
   • Microsoft Customer Agreement (MCA)
   • Microsoft Online Services Program (MOSP)

If the user has several billing scopes, use Cost Management + Billing > Billing scopes and check each account. ^1^

2. Find who can accept the private offer

The required person depends on the agreement:

These are billing roles—not the Microsoft Entra Global Administrator role or the Azure subscription Owner role. ^2^

Enterprise Agreement

A user who can access the enrollment should open:

Azure portal > Cost Management + Billing > Billing scopes > select the EA billing account > Access Control (IAM)

That page lists the enrollment’s Enterprise Administrators. Existing EA administrators can also add another administrator through + Add > Enterprise administrator. Only an existing EA administrator can create another one. ^3^

If no active EA administrator can be reached:

1. Open an Azure support request.
2. Include the enrollment number, relevant account details, authentication type, and approval from an existing Enterprise Administrator when available.
3. If there is no active Enterprise Administrator, contact the organization’s licensing partner to update the EA contact information. ^3^

Microsoft Customer Agreement

Open:

Azure portal > Cost Management + Billing > select the billing account > Access control (IAM)

The role-assignment list shows the Billing Account Owners and Contributors. Billing Account Owners, Contributors, and Readers can view billing-account role assignments, but only an Owner can grant billing-account permissions. ^4^

If nobody available can see the MCA billing administrators, a Microsoft Entra Global Administrator can conditionally recover access:

1. Open Cost Management + Billing > Billing scopes.
2. Enable the option to view all billing accounts.
3. Select the MCA billing account.
4. Open Access Control (IAM) > Add.
5. Assign yourself Billing account owner.
6. Review the billing-account role assignments.

This elevation applies to MCA or Microsoft Partner Agreement billing accounts, not EA enrollments. ^5^

3. Separately identify who can purchase or subscribe

For EA and MCA private offers using separate acceptance and purchase:

1. Open Subscriptions and select the intended subscription.
2. Select Access control (IAM).
3. Select View access to this resource.
4. Find users assigned Owner or Contributor.

For VM software reservation offers, the required purchaser is a subscription Owner or Reservation Purchaser; Contributor alone is insufficient. For MOSP, the Account Administrator performs both acceptance and purchase. ^2^

These assignments identify users with the required subscription role, but do not by themselves guarantee a successful purchase. The billing account must also be eligible, Marketplace purchasing must be enabled, purchase controls and Private Marketplace approvals must permit the offer, and the subscription must align with the offer’s billing account and directory. ^1^

Eligible single-click purchases combine acceptance and purchase submission, but they do not eliminate the underlying billing, subscription, policy, or organizational authorization requirements. ^2^

Product enhancement request

There is no documented commitment for a tenant-wide purchaser directory. To request one, open Azure portal > Help + Support > New support request, choose Billing or Subscription management, then Marketplace, and ask that the administrator-discovery enhancement be routed to the Marketplace product team. This creates a trackable request but does not imply roadmap commitment. ^6^
