Hi. I have clients where the client email address and the billing email address are different. Where enter and how make work?

Hi cortex,

Welcome to the QuickBooks Online Community! QuickBooks Online includes some great features and customization options, allowing you to control the default email addresses for transactions. I know some customers require different departments to receive the same invoice, and it's important to provide this in an efficient and convenient manner. As a QuickBooks user, you're equipped with the tools required to make this simple and automatic. I'll be happy to guide you through getting started.

You can easily have multiple email addresses assigned to a customer or supplier by separating them with a comma. This will apply as the default email address for future invoices, and I can personally confirm it will send to both addresses. Entering a space after the comma is optional, and will have no effect. Please not that the email field has a limit of 100 characters.

Let me know if this works for you!
