The company name and address information there is pulled from the information under settings->company->summary
If you want the customers to make the check out to a different name from the one you have under the "Make checks payable to:" portion, you can add it to the invoice introduction for that agreement by going to settings->agreements->click on the agreement->go to the bottom and click on invoice introduction and add the information there.
It will show up on the invoice near the top.
