QuickBooks Emailing Invoice: Required Information

What is the required piece of information to click 'Save and Send' when emailing a customer invoice in QuickBooks?

A. Tags
B. Billing address
C. Customer email
D. Invoice number.

Final answer:

QuickBooks requires the customer's email address to send an invoice. Other details like tags, billing address, and invoice numbers, although important, are not necessary for sending the invoice.

Explanation:

When emailing a customer invoice in QuickBooks, the required information to click 'Save and Send' is the Customer Email. This is critical because QuickBooks needs to know where to send the electronic invoice. While tags, billing address, and invoice numbers are important pieces of information in many circumstances, these are not required to send an invoice via email in QuickBooks. Without the customer's email address, QuickBooks cannot complete this task.
