What are some prequalifying questions to see if a customer is eligible for purchasing in Azure Marketplace?
Azure Marketplace requires that customers have a Microsoft Entra ID and an active Azure subscription. If both requirements aren't in place, the customer is asked to create them in the purchase flow. Azure Marketplace supports credit card payments or invoicing. Offers purchased through Azure Marketplace are automatically added to customers' Azure bill and are charged according to the payment method associated with their subscription. Keeping in mind that users need the appropriate permissions and roles to purchase which in most cases are the subscription owner or contributor.
