Which of the following features helps users manage invoices and notes efficiently in Sage Accounting?

The To Do List widget is specifically designed to help users manage their tasks, including invoices and notes, in an efficient manner. This feature allows users to keep track of outstanding tasks, deadlines, and important reminders in one centralized location. By having a clear to-do list, users can prioritize their work, ensure timely follow-up on invoices, and maintain proper notes related to their accounting activities. This organized approach enhances productivity and ensures that no critical tasks are overlooked.

The other features listed may contribute to the overall functionality of Sage Accounting, but they do not directly target the management of invoices and notes in the same way. Graphical reports provide visual representations of financial data, comprehensive spreadsheets assist with data organization and manipulation, and summary dashboards offer an overview of key metrics and performance indicators. While these tools are valuable, they do not provide the same focused task management capabilities as the To Do List widget.
