Hi @Rafal_Majewski, welcome to the forum!

You will be able to update your payment information directly from the billing section of the Admin Console if you upgrade or your Organization or via the Team Settings if you upgrade a Team.

When you are upgrading your plan, you will need to click “Plan group” and select the entire a specific Team instead of the entire Organization.
I recommend you checking more details in this article and if you have any questions you can also contact our support team: How to contact our Support Team email
I hope this helps!
