Local development workflow for Fondo startup tax and bookkeeping integration. Provides a fast feedback loop using CSV exports and mock financial data so you can build dashboards, R&D credit calculators, and burn-rate tools without waiting on live Fondo reports. Toggle between mock mode for rapid iteration and real export parsing for production validation.
