How can I change the name and company information used in my invoices?

The company information used in your invoices (shown on your company settings page) comes directly from your ProZ.com profile. The address and tax ID are those you specify in your profile. The "name" is either your company name (if you have specified one) or your personal name as it appears on the site (your full name or just your login, depending on the preference set in your profile).

To change the name and company information in your invoices, just change that information in your profile.

Alternatively, you can also create a new custom invoice template, and specify your company information exactly as you wish it to appear. Please note that this means the contact information in your invoice could become out of sync with the contact information in your profile; when your contact information changes, you would need to update it in both places.
