Hi Vítor,
Thank you for reaching out. NO_SIGNUP_PERMISSION error occurs when you don’t have permission to set up billings. Billing setups can only be created by customers who have permission to set up them. You may contact a representative for help setting up permissions.

Hi Vítor,
Thank you for reaching out. You would need to ask your Google representative or your technical account manager for help setting up permissions. By logging into your google ads account you could not change those permissions settings.

Hi Vítor,
Thank you for reaching out. If you were previously assigned a Google account manager or representative then you can reach out to them. Otherwise, I doubt you could request for an account manager or representative. You could refer to this article for more information.
