Multi User Registration - Company Membership

We want to offer a “Company” membership that will allow them to pay for 5 users.

$xxx = Company (up to 5 users)

Once they pay $xxx through stripe checkout, how can we give them access to sign up each of the 5 people? Do we have to do this manually, or can we create a form that populates airtable but knows they are under the company’s paid account?
