Thank you for posting here in the Community, @neongod.
I'll provide you with some tips on how to enter your Company EIN and VAT number in your invoices.
You can add your EIN and VAT number to your invoice using QuickBooks Online. You only need to enable a custom field and assign it to your VAT number. Just so you know, each time you make an invoice with QuickBooks Online US, you'd have to manually enter your VAT number. Custom fields are available for Plus and Essentials or Advanced.
You can follow these steps:
- Go to the Gear Icon.
- Select Custom Form Styles.
- Find the invoice template you'd be using.
- From the Action column, select Edit.
- Click the Content tab.
- Select the Custom field link.
- Put a checkmark on one of the Custom field boxes.
- Enter VAT ID as its name.
- Hit Done.
