The Billing Settings for an individual DocHub account and an organization are kept totally separate. The same goes for the credit card details. If you'd like to transfer Pro to your organization, you'll see an option to migrate the subscription in your organization's Billing Settings.
See the steps and the screenshot below for reference:
Select the organization profile from the drop down button at the top left side of your dashboard page then go to the organization Settings.
Go to "Billing" tab
Click the "Migrate DocHub Pro to Group" option
