To display your company’s VAT number on your customer’s invoices, you can add it under your account’s tax settings(Settings > Configure Chargebee > Taxes) for the respective regions. 


For the EU region, if you are VAT MOSS registered, you can add your VAT number while adding your tax rate the first time.



If you are not registered for VAT MOSS, you can add the VAT number for each country that you’re collecting taxes from. For this, click on the edit icon beside the country name and fill in the VAT number and edit the tax rate if required.




Note: The VAT registration number that you add with your organization address(Settings > Configure Chargebee > Business Profile) is not picked up to be displayed on customer invoices since you may have multiple tax registration numbers if you are providing a service in multiple countries.
