I’m trying to find an app for my iPad that I can use to track my ww’ing projects, customer orders, as well as general invoicing for items sold. I need something simple, easy to use and doesn’t bust the bank. I really like free, but I’m also ok with low cost. I found one that is a strong heavy hitter but it’s $500 a year and it does WAY more than I need/want.

What do you do for this type of stuff?
