How do I personalize my customer account information?

In your customer account, the information you provide is used to appear on your invoices.

If you prefer to have your company name on your invoices instead of your first and last names, you can edit these fields to add the text of your choice.
If you wish to add your VAT number, you can use the field "Line 1" for this purpose and keep "Line 2" etc. for your address.
