As an Amazon seller, several key reports are crucial for financial management. Start with the Statement of Operations (Profit and Loss) from Amazon Seller Central, which shows your sales, fees, and other charges. The Balance Sheet report helps track your assets, liabilities, and equity. For inventory management, use the Inventory Health report. The Sales and Traffic report gives insights into your sales performance. For tax purposes, the Transaction View report provides detailed breakdowns of all financial transactions. Outside of Amazon, maintain a cash flow statement to monitor your liquidity. Regularly review your aged receivables (if applicable) and payables. Consider creating a dashboard that combines key metrics from these reports for a quick overview of your business health. An accountant can help you interpret these reports and use them for strategic decision-making.
