What is the primary function of a "class" in QuickBooks Online?

The primary function of a "class" in QuickBooks Online is to categorize different departments or projects. Classes are an important feature that allows users to track financial data in a way that is meaningful for their business. By assigning classes to transactions, users can generate detailed reports that provide insights into the performance of various segments within the organization. This could include tracking income and expenses for different departments, projects, or locations, enabling better decision-making and resource allocation.

This functionality is particularly beneficial for businesses that operate in diverse areas or have multiple ongoing projects, as it allows for a clear view of profitability and operational efficiency for each category defined by the classes. Thus, utilizing classes effectively can enhance financial reporting and management capabilities within QuickBooks Online.
