What can you do to create a new tag if it is not listed in the existing tags for an invoice?

To create a new tag that is not listed with the existing tags for an invoice, both the option to start entering in the Tags field and select + Add and the option to use the Manage tags link in the Gear menu are valid methods.

When using the Tags field on the invoice, typing in a new tag that doesn’t already exist allows you to create a custom tag instantly. By selecting the + Add option that appears, you can save this new tag for future use, making it a quick and efficient way to categorize your invoices with personalized tags.

Additionally, accessing the Manage tags link in the Gear menu allows you to view all existing tags and provides the functionality to create new ones outside the context of a specific invoice. This option is particularly useful if you want to prepare and manage your tags in a centralized location, enabling better organization and maintaining consistency in tagging across various invoices.

Therefore, the correct answer encompasses both methods, demonstrating that there are multiple effective ways to create new tags within the invoicing system.
