GAAP Accounting Services San Francisco Bay Area

Tax services for small businesses

Generally Accepted Accounting Principles (GAAP) refer to a common set of accounting rules, standards, and procedures established by the Financial Accounting Standards Board (FASB). Public companies in the United States must follow GAAP when preparing and presenting their financial statements. These standards ensure that every balance sheet, income statement, and cash flow report is consistent, transparent, and comparable across industries and time periods.

At TNZ Accounting, we specialize in GAAP-compliant accounting services for startups, private companies, and corporations throughout the San Francisco Bay Area. Our goal is to ensure your financial statements are accurate, fully compliant, and ready for investors, lenders, and regulatory review.

What Is GAAP Accounting?

GAAP is guided by ten key principles that shape how financial data is recorded and presented — including consistency, regularity, prudence, and full disclosure. These rules create a standardized framework for preparing financial reports that are reliable, uniform, and easily understood by external parties such as auditors, investors, and board members. GAAP is often compared with the International Financial Reporting Standards (IFRS), a global set of accounting guidelines. While IFRS is principles-based, GAAP is rules-based, ensuring that every entry follows clearly defined standards. The purpose of GAAP is to make financial statements complete, consistent, and comparable, allowing stakeholders to identify trends and assess performance over time with confidence.

Why GAAP-Compliant Accounting Matters

Accurate, GAAP-based financial reporting does more than satisfy compliance requirements — it builds credibility and trust. Whether you’re seeking investors, applying for business loans, or preparing for an audit, GAAP accounting demonstrates that your company operates transparently and responsibly.
