+## Tenant Usage, Billing and Subscription Management
+
+For your convenience, NetBird provides a daily usage overview.
+Please note that the usage displayed in the MSP portal may differ from what you see when switching to a tenant account.
+This is because the MSP portal shows billable usage — meaning only active users and machines are counted
+(see [NetBird plans](/how-to/plans-and-billing#net-bird-plans) for more details).
+
+The usage data is refreshed once per day and reflects the number of users and peers that will be included in your billing at the end of the cycle.

+
+Each tenant you add is treated as an individual Stripe subscription under your MSP account. When you go to Manage Plan
+in the 'Plans & Billing' section, you'll see a list of subscriptions — one for each tenant.
+
+However, you’ll only be charged once, with the total consolidated amount across all tenant subscriptions.
+A single consolidated invoice is generated for your convenience, which you can download from the 'Tenants' overview page.
+
+<Note>
+    All tenant billing cycles are automatically aligned with your MSP account's billing cycle.
+    For example, if your MSP subscription starts on March 2nd and you add a new tenant on March 15th,
+    the tenant’s billing cycle will still be set to March 2nd. As a result, the first full-month charge will occur on April 2nd.
+</Note>
+
+## Free Trial for Tenant Accounts
+
+To make things easier for you, all new tenant accounts come with a 14-day free trial. This gives you the perfect opportunity
+to showcase NetBird to your customers before committing to a paid plan. Simply select 'Continue with Free Trial' when
+setting up a new tenant plan.
+
+## Delayed Tenant Domain Verification
+
+Just like with the free trial, you have the flexibility to verify your tenant's domain at a later time, making it easier
+to demo NetBird to companies that aren't yet your customers. However, if someone logs in using the same domain, NetBird will
+create a separate account to avoid any security risks. We hope that the ease of use and advanced security features of NetBird will help drive
+your business growth and attract new customers.
