Invoice: This indicates the purpose of the commercial document and should be placed near the top of the page. Name of your business: Format in bold and place at the top of the page. Include your company logo for a branded look. Seller contact information: This not only lets your customer know how to contact you if they have any questions about the invoice, but could also lead to future business; if they are happy with their experience working with you, they might use the information to contact you again or refer you to a friend.
A professional header: The first item on your freelance invoice should be your business name, or your full name, in professional (and easy to read) font. The font size should be a little bigger than the rest of the text on the invoice, and possibly even bolded for emphasis. Next you'll want to include your contact information: your mailing address, phone number, email address, website, etc., right underneath your business name.
