What is SignalOS?
SignalOS is an intelligent practice management platform built for modern accounting firms. We combine streamlined client onboarding, work management, document collaboration and billing into one cohesive system so your team can focus on delivering high‑value advisory work. Our goal is simple: help firms operate efficiently, reduce risk and grow profitably.
Unlike generic task tools, SignalOS understands compliance‑driven workflows. Role‑based access control, secure file exchange and automated reminders keep engagements moving while protecting sensitive client data. Firm owners get real‑time visibility into budgets and utilization, while staff get a clear picture of priorities and due dates.
Whether you are a boutique firm or an expanding multi‑office practice, SignalOS scales with you. Start with the essentials and add modules as you grow—without duct‑taping multiple tools together or losing context across systems.
