Three Sheet Model

The Three Sheet Model is a fundamental financial modeling tool that consists of three main components:

  1. Income Statement: This sheet focuses on the company's revenues, expenses, and profitability over a specified period.
  2. Balance Sheet: The balance sheet provides a snapshot of the company's assets, liabilities, and equity at a particular point in time.
  3. Cash Flow Statement: This sheet tracks the inflows and outflows of cash, categorizing them into operating, investing, and financing activities.

The waccy package provides a ThreeSheetModel class that allows you to create and manipulate a three sheet model easily. It includes methods for inputting data, calculating financial ratios, and generating visualizations.

Forecasts based on Non-Financial Information

In addition to traditional financial data, waccy enables you to incorporate non-financial information into your forecasts. This can include factors such as:

  • Industry trends
  • Market share and competitive landscape
  • Technological advancements
  • Regulatory changes
  • Macroeconomic indicators

By considering these non-financial aspects, you can create more comprehensive and accurate forecasts. The Forecast class in waccy provides methods for integrating non-financial data into your financial models.

Data Sources

EDGAR

waccy includes functionality to retrieve financial data from the Electronic Data Gathering, Analysis, and Retrieval (EDGAR) system, which is maintained by the U.S. Securities and Exchange Commission (SEC). You can access company filings, such as 10-K and 10-Q reports, to extract relevant financial information.

The EdgarDataSource class allows you to search for and download specific company filings programmatically.

QBO and other Accounting Software

waccy provides integrations with popular accounting software, such as QuickBooks Online (QBO), to import financial data directly into your models. This streamlines the data collection process and ensures accuracy.

The QBODataSource class enables you to authenticate and retrieve data from your QBO account, while the AccountingDataSource class serves as a generic interface for integrating with other accounting software.
