Define default payment method per account on aws

Question

There's documentation on aws about how to set the default payment method for an account here. In my case, I have a organization with non-consolidated billing (several companies sharing an aws console). I would like to set a default payment method per earch account, is that possible? I haven't been able to find a solution.

NOTE: The default payment is for organization and I would like it to be per account (corrected text)

Answer

**Here's a general approach you can take:**

**Set Up Billing Alarms:** For each account in your organization, configure a billing alarm using AWS Budgets or AWS CloudWatch. Define a budget with a threshold that corresponds to the expected charges for that account. If the charges exceed the threshold, the alarm will trigger.

****Configure Actions:** **When the billing alarm triggers, configure it to perform actions such as sending SNS notifications or invoking Lambda functions. You can use these actions to notify account administrators or perform automated tasks, such as disabling non-essential services or prompting users to update their payment methods.

**Monitor and Manage:** Regularly monitor the billing alarms and take appropriate actions as needed. Ensure that account administrators are aware of any billing issues and have the necessary information to update payment methods if required.

Answer

If you have AWS Organization, you definitely have consolidated billing. 
AWS Organization has two modes:
* Consolidated billing
* All features (It includes all the functionality of consolidated billing, plus advanced features)

If you have AWS Organization, you can only set a payment method for the Management (payer) account
