Hi there, @SuperStar777. 

Thanks for coming back. At the moment, the status of the invoice with a credit note will only show as Paid when it's applied in the Receive Payment page. 

I know how relevant for you and your business to have your invoice status marked as CN Applied or Applied. Letting us know what works best for you and your business will show our developers what they need to consider in future product updates. 

I'll send feedback or a feature request about this functionality. In the meantime, I encourage you to visit the QuickBooks Blog for more product updates. 

Let me know if you require additional help. We're always to help you more. Stay safe.
