LEDGERLINE

Revenue analytics a CFO would trust, shipped as a working app

Ledgerline is a subscription-revenue analytics dashboard: a 12-month MRR area chart with hover crosshair, diverging MRR-movement bars, an invoice table with dunning alerts, and a ⌘K command palette. Every chart is hand-rolled SVG, zero chart libraries, in a Linear-grade near-black interface.
