What feature must be used to add optional company information during the EasyStep interview?

To add optional company information during the EasyStep interview in QuickBooks, the Advanced Setup feature is utilized. This feature allows users to delve deeper into customization options and gather additional details that can enhance the company's profile in the software.

The EasyStep interview is an initial setup process that guides users through the basic configurations needed to get started. While other features such as the Chart of Accounts are critical for managing financial transactions and tracking income and expenses, they do not pertain to the optional company information that users might want to include at the setup stage. Data file backup is important for ensuring the security of financial data but does not relate to initial company setup or customization. Similarly, the Home page serves as a dashboard for navigating QuickBooks but does not provide tools for entering optional information during the setup process.

Using Advanced Setup ensures that users can fine-tune their company profile, which may include additional fields relevant to their business model, helping QuickBooks function more effectively to meet the unique needs of the organization.
