To be able to monetize with Ossa, you need a complete Stripe account. A complete account means that you've added all of the information that Stripe requires.
If you see the alert in the screenshot below indicating that your Stripe account is incomplete, click the "GO" button to be directed to your Stripe account dashboard. There, you will be able to finalize your account by adding all required fields.
Once you finish setting up your Stripe account, this alert will disappear and you will be able to start receiving offers from brands.
