I'm sure MS Word isn't even close to the proper app to use for invoicing, but in the beginning, I didn't need anything extravagant. At the time, I just wanted to have something on paper to show who I billed and what I billed them. My business has grown quite a bit since then, and I've constantly battled with which way I should go in order to create a real business invoicing environment (without having to spend too much time dealing with it) - that's why I chose Word in the beginning because I don't want to take too much time outside of my actual work just to set up a billing environment. I had originally created a bill in Excel and ended up pasting it into Word, and have always stuck with Word from then on. I will try Excel again... thanks
