The problem
Small churches track money in notebooks and scattered spreadsheets, and every new treasurer starts from zero.
What I did
Accounting built for treasurers who are not accountants: income, expenses, accounts and Excel export, with a mobile app for day-to-day entry.
Where it stands today
A subscription SaaS in production, billing through Stripe, with paying organizations active and a companion app live on the App Store and Google Play.
