Hi shaunmccullough,

At this time the invoice feature within QuickBooks only applies to individual customers you have set up within the system. I think this would a really interesting feature to add into QuickBooks and I wouldn't be surprised if other users have also had the same idea in mind. I encourage you to follow the steps below and share this product suggestion with our product development team to help improve the experience in QBO!

1. Select the Gear icon at the top, then Feedback.
2. Enter your comments or product suggestions then select Next.
3. You'll be provided a list of suggested Help articles related to your comment. You can read through them or select Skip and send message.
4. From the drop-down, choose the appropriate category, then select Send message.

Thanks,

-Steven
