'Your account is non-billable. The bank account linked to your merchant account will not be billed'
is shown on install popup
Per your question yesterday, you were trying to test billing features on Sandbox, I assume you are trying to do the same on production, is that correct? If you have just created a developer account in production you are going to have similar issues in prod, mainly that the merchant associated with your developer account is just a test. Let's continue this in the other thread.
