Finally got around to making a nicer invoice for my clients (instead of the ugly Word document) in Photoshop. It's based heavily (too much maybe?) off the invoices I've seen on Freshbooks, Ballpark and Blinksale.
Anyways, the link has the PSD if anyone else wants to use it. If you have a nicer one please post a snap, or a link to download if you don't mind others using it!
