This is a fantastic example of how to build a service that doesn't target the usual tech-savvy crowd, but regular brick and mortar businesses, where pen and paper is still the default toolset. These are often overlooked. I see it everyday: I work at a company that manufactures running shoes in Germany and the retailers we sell to are mostly small, very competent running stores for enthusiasts - not your average national chain like Runner's Point. However these stores barely have any digital inventory/order/customer management solution, use way overpriced point of sale systems and often resort to fax machines when submitting an order. Well, what I'm trying to say is that there are potential customers for useful niche services left and right. It's just not always very obvious. What you're doing, looks great though.
