ConFlow is a macOS workflow software integrating client and mandate management, time tracking, invoicing, and financial tracking into one offline application. It consolidates client details, project mandates, session tracking, and billing in a unified interface. Flexible billing models, including hourly rates, session fees, and package pricing, are applied per mandate. Time tracking records session dates, durations, activities, travel time, and expenses, with document storage for mandates. The invoicing system generates DIN 5008-compliant invoices with hour documentation and QR codes for payments. Features include client communication, appointment scheduling, follow-up task tracking, and payment monitoring. The Pro version adds EN 16931-compliant e-invoicing, profit and loss statements, analytics, and expense tracking with tax calculations. All data is stored locally, with no external servers. ConFlow operates offline and supports macOS 10.15+ on Apple Silicon and Intel processors.
