Finviz is a financial data and analysis platform, not a CPA firm. It provides a wide range of financial information, including stock market quotes, charts, news, and analysis tools to help investors make informed decisions.

On the other hand, CPA firms are professional service firms that offer accounting, auditing, tax planning, and consulting services. They help individuals and businesses manage their financial records, ensure compliance with tax regulations, and provide financial advice.

Therefore, the main difference between Finviz and other CPA firms is their core focus and service offerings. Finviz primarily focuses on providing financial data and analysis tools to investors, while CPA firms focus on delivering comprehensive accounting and financial services to clients.
