Any idea if quickbook is have the function to link IRBM MyInvois Portal. This is in malaysia

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.
 

1. Log in to your QBO account.
2. Select Apps from the left menu, then choose Find apps.
3. Type IRBM MyInvois Portal in the search bar.
    

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.
