A subscription licence can be installed on multiple M365 tenants.
That doesn't apply to the Freemium subscription
If the PDF app is installed on multiple tenants, the same subscription can be applied. The licencing is user-based, not tenant-based.
e.g. - if an organization has three tenants, it only needs to purchase one subscription.
If your organization has more than 100 users, please contact sales.
Our payment gateway is Recurly. That will appear on your credit card statement.
A single subscription may be used across multiple organizations. Because the subscription model is user based, we don't mind whether there are two subscriptions for 50 users - or 50 subscriptions for 50 users. Ours is a user-based subscription model
