Accounting Principles Made Simple explains the foundations of Generally Accepted Accounting Principles (GAAP) and how they shape financial reporting in the United States, including what GAAP is, why it was developed, and how it compares with International Financial Reporting Standards (IFRS). It introduces core accounting concepts such as debits and credits, double-entry accounting, the chart of accounts, the general ledger, T-accounts, and trial balances, with definitions supported by practical examples. The book is written for beginners who need a structured overview of accounting basics, including small business owners, early-stage entrepreneurs, and readers building bookkeeping skills for work or study. It outlines how to choose between cash and accrual accounting, then walks through the accounting cycle and closing process, including common closing entries. Later chapters cover selected GAAP-related applications such as depreciation methods, amortization and intangible assets, inventory and cost of goods sold (including FIFO, LIFO, and average cost), and selected financial ratios, presenting an explanatory, example-driven approach rather than a technical reference.
