Harmonic Accounting started with a vision: financial harmony & clarity.
Founded by Lotte Leussink, a passionate advocate for female entrepreneurs, the firm was born from a frustration – the lack of clear, ongoing financial guidance for business owners in addition to monthly bookkeeping. Lotte saw the need for not just on-going number crunching and organizing, but also ongoing communication, support, and education.
This client-centric approach has empowered over 100 female entrepreneurs over 8 years to not only better understand their numbers and business finances in general, but to leverage them for informed decision-making, growth, and achieving a healthy balance & harmony in their businesses.
Based in NYC, Harmonic Accounting works with service-based, e-commerce organizations across the United States.
