There are many financial modeling software available in the market, each with its own strengths and weaknesses. Popular and widely used software include Excel, Google Sheets, PlanGuru, and Finmark. Excel is the most common and versatile spreadsheet application that can be used for financial modeling, however it can also be prone to errors, difficult to audit, and limited in scalability and collaboration. Google Sheets is a web-based spreadsheet application with similar features and functions as Excel, but with added benefits of cloud storage, real-time collaboration, and integration with other Google services. PlanGuru is designed for small businesses and startups, offering features and functions that can help create income statements, balance sheets, cash flow statements, budgets, and forecasts. Finmark is designed for startups and founders with features and functions that can help create financial models based on business model, revenue streams, expenses, and growth drivers. However, these software can also be expensive, complex, less secure, less powerful, less customizable, less comprehensive, and less compatible with some formats and tools than spreadsheet applications.
