ideas re: invoice template

On the invoice, can you put the firm name accross the top, and invoice as the title of the document instead. Also, and this is important, can you refer to the client as client instead of customer? Lastly, can you not refer to the last colum as "price" but rather simply "Amount." In my opinion, that would make for a far more professional and suitable invoice. Additionally, if the firm has a logo, as mine does, can you allow me to upload my logo so that ti appears at the top of the invoice?
