I want my supplier to email me their invoice straight into quickbooks. How do I do this?

I recognize how important it is to receive supplier invoice directly to QuickBooks, @Mike OM.

The ability to email invoices from your supplier directly to QuickBooks is unavailable. Since this option is unavailable, I'd suggest sending feedback to our product developers for this feature in QuickBooks Online to help improve your experience.

Here's how:

1. Go to the Gear icon.
2. Choose Feedback.
3. Enter your comments or product suggestions.
4. Then, click Next to submit feedback.

You may also visit our Feedback forum page. From there, you can see a list of other QuickBooks users who already suggested this feature, as well as the recent updates in QuickBooks.

I've also included the resources below that can help you how to handle customer transactions in QuickBooks Online:

• Record invoice payments in QuickBooks Online
• Customise invoices, estimates, and sales receipts in QuickBooks Online

Always know that your feedback are ways on how we can improve the system more. Please don't hesitate to post your question here in the Community if you need anything else. Take care!

You need a 3rd party app to do so.
