Where would you start importing a set of rules downloaded from another QuickBooks Online company?

To begin the process of importing a set of rules downloaded from another QuickBooks Online company, you would navigate to the Transactions section and select the Rules tab. This location is specifically designed for managing rules pertaining to transactions, such as automated categorization of expenses and income based on certain criteria. The Rules tab provides the functionality to not only view existing rules but also to import new rules from external sources.

Utilizing this specific section ensures that all rules are consolidated in one area, making it easier to manage and streamline transaction handling in QuickBooks Online. In contrast, other options do not direct you to the appropriate functionality for rule importation: Banking > Settings would lead to general banking settings and not rules management, Lists > Manage Rules is not a current feature in QuickBooks Online, and Tools > Import is typically reserved for importing lists and data, not specifically designed for transaction rules.
