How to merge an individual invoice to another customer

Hi tina-magnotta,

Welcome back to the Community. QuickBooks is a flexible program that helps you get your work done faster. I'll be happy to share more info so you're on the right track with achieving your QuickBooks goals. 

To get started, I'd like to make sure I'm on the same page as you. Are you looking to add two customers to one invoice? If so, it's important to note that this function isn't available in the program. I recommend sending feedback about this to our engineers so it can be considered in the future updates. To send feedback, click on the Gear icon > Feedback. 

Otherwise, feel free to ask other questions, I'm here to steer you in the right direction.
