My story is similar. My friends wife was selling Indian women clothes and I took a stab at re-jigging her business for the "messaging-first" world. worked like a charm. she is now selling a very non-differentiated product at the rate of 1 every 20 working minutes. :-)

so now we have good problems to solve like actually needing a CRM, invoicing etc that I hoping to do via a web app.

Once that is done, it could be sold to other similar businesses. I have already done some presales using my mockups and there is interest.
