Hello nighthawkservice,

Thanks for reaching out to us here.  Missing invoices can have a negative impact on your day.  QuickBooks Online provides the option to review all activity within your books.  To see if the invoices have been edited, or deleted, follow these steps;

1. Go to your Settings ⚙, and open Audit log under Tools

2. Select a Date range 

Another possible cause possible for missing invoices could be due to browsing data.  Temporary files can cause unexpected behavior.  Here's how to clear cache on your browser. 

Should you require additional assistance, please don't hesitate to contact us.  It would be our pleasure to work with you in real time, and review the issue in more depth from our end.
