If you don't want to use Pegasus or another paid product (presumably because of the cost), the packages I'd reach for are django-allauth for login/user stuff and dj-stripe for the Stripe integration. As for teams, there wasn't a library I was happy with so I rolled my own for Pegasus, but some people like django-tenants. It's too heavyweight for my taste as it requires a more complex dev/test/infrastructure setup with Postgres schemas, as opposed to having a single-database and handling multitenancy in the application layer. But there are pros and cons to both approaches.
