A web app where business owners can keep track of financial info, create user accounts for different functions (accounting, data entry, etc.), and have a dashboard that lets them get a quick view of their financials and reminders for any financial tasks (taxes, etc.).
Steven DBased on my experience, these entrepreneurs are most short on time and attention. Signing up on and learning a new "system" or app is perceived as a huge barrier. Even finding out that the app exists is a barrier. So the solution probably needs to offer something utterly essential to spur adoption.
