Pilot error, feel free to delete this post.

When an order comes in, I naturally clicked on invoice because I wanted to process the order. It wasn't until later in the day when I clicked on "EDIT" that I discovered that is where the CC information is stored.
This button, in my opinion, is named wrong. For one thing, you can't really edit anything, it is about processing. The "EDIT" button should be called "PROCESS".
