     * To convert your trial to the Azure marketplace you need to create a deployment in the Azure console. Just delete the new deployment if you don’t need it. After you create the new deployment your marketplace subscription is ready.
     * Any deployments created during your trial won’t show up in the Azure console, since they weren’t created in Azure, but they are still accessible through the [{{ecloud}} Console](https://cloud.elastic.co?page=docs&placement=docs-body) and you are billed for their usage.
 
+$$$azure-integration-native-trials$$$Can I sign up for an Azure trial directly from the Azure marketplace?
+:   Yes. We now support a 7-day trial for the Azure Native ISV offering. You can start a trial by creating a deployment through the Azure Marketplace. Please note the following:
+
+    * The email associated with the Azure account used to create the deployment must not already be linked to an existing Elastic organization.
+    * During the 7-day trial period, there are limits on the number of deployments or serverless projects you can create. If you want to convert to a paid subscription early and use full Elastic features, please contact `support@elastic.co`.
+    * After 7 days, the trial will automatically convert to a paid offering. You may contact Elastic Support to unsubscribe, but doing so may result in your resources being deleted after a grace period.
+    * The trial is available only once per user account. After it expires, you cannot start another trial. If you need a trial extension, please reach out to Elastic Support.

 $$$azure-integration-billing-different-deployments$$$How do I get different Elastic deployment/resources charges to different Azure Subscriptions?
 :   See [Integrated billing](#ec-azure-integration-billing-summary). To have different Elastic deployment/resources costs reported to different Azure subscriptions, they need to be in separate {{ecloud}} organizations. To create a separate {{ecloud}} organization from an Azure subscription, you will need to subscribe as a user who is not already part of an existing {{ecloud}} organization.
 
+$$$azure-resubscribe-flow$$$How can I resubscribe to an Azure subscription?
+:   If your organization is currently unsubscribed from the Azure Marketplace, you can resubscribe through any of your existing Azure deployments in the Azure Portal:

 $$$azure-integration-billing-elastic-costs$$$Why can’t I see Elastic resources costs in Azure Cost Explorer?
 :   The costs associated with Elastic resources (deployments) are reported under unassigned in the Azure Portal. Refer to [Understand your Azure external services charges](https://learn.microsoft.com/en-us/azure/cost-management-billing/understand/understand-azure-marketplace-charges) in the Microsoft Documentation to understand Elastic resources/deployments costs. For granular Elastic resources costs, refer to [Monitor and analyze your account usage](../../cloud-organization/billing/monitor-analyze-usage.md).
