Hello, @florance1750.
QuickBooks Online (QBO) allows integration for several third-party apps or software. Let's go to the apps menu to verify if IRM MyInvois Portal integrates with QuickBooks.
Once you're able to find the app, let's go ahead and download it.
Moreover, I'm adding this article for guidance on how you can personalise your invoices in QBO: Customise invoices, estimates, and sales receipts in QuickBooks Online.
If you have further questions about integration or any other concerns within QBO, please don't hesitate to get back to us by replying below. We're always here to help you. Have a good one.
