Here's how to add an external person to your Stripe account for online payments:
Log in to your Stripe account and click on the little wheel to access your account settings.
Select Team and Security
Click on New member and enter the person's e-mail address and the role Administrator
The new member will receive an invitation e-mail, and will then need to follow the instructions to create an account or connect to Stripe.
💡 Once the person has met your needs, you can remove the access without any problem.
