How to update my invoice with my tax settings

The "Correct name and address" button often defaults to Payment Preferences. To fix this for your existing invoice:

1. After updating your Tax Settings (as suggested by the re:Post agent), go back to the Invoices page.

2. Click "Correct name and address" again. You should now see an option to select your Tax Registration information instead of your default payment profile.

3. If the system still limits your name length or doesn't show the new settings, I think you Need to open a Billing Support Case in the relevant AWS Account -> https://console.aws.amazon.com/support . Ask them to "manually regenerate the invoice using the Business Legal Name from my Tax Settings," as the Payment Preference field is technically restricted to 50 characters.

To update your company name on your invoice using tax settings, you should update your business legal name directly in the Tax Settings section of your AWS account. This is separate from the Payment Preferences section.

Here's how to update your business legal name in Tax Settings:

1. Navigate to Tax Settings in your AWS account
2. Select the checkbox next to your account name
3. Choose "Edit" from "Manage tax registration"
4. Update your business legal name
5. Confirm the address
6. Choose "Update"

Your account's address and the information in Tax Settings determine the applicable taxes and the appropriate AWS seller of record for your AWS Invoices. Tax Settings allows you to manage your Tax Registration Numbers, business legal name, and business legal address for all your AWS accounts.

Since Tax Settings is specifically designed to manage your business legal name for tax and invoicing purposes, it should accommodate your full company name without the character limitations you're encountering in Payment Preferences. The business legal name you set in Tax Settings will be reflected on your invoices, while Payment Preferences is primarily used for payment processing and billing contact information.

Make sure to verify that you have the correct billing address set up in Payment Preferences for your management account, as this works in conjunction with your Tax Settings to ensure accurate invoicing.
