Agreed. Solid idea. Well executed. Demand Exists. But you need to narrow scope, at least initially. It would be very difficult to just focus on "invoices." Going up against some strong SEO competition there. Like jwheeler79 suggests, focusing on a very narrow market segment may be easier to gain some traction. There a tons of small sellers on Amazon, Ebay, etc., that may have very specific document needs that are not being met. They are probably using clunky, unprofessional solutions or trying to do it themselves. Find out what those needs are and very specifically market to them.
