Hello, bf4.

 Any changes made in your invoices would only show in your QuickBooks’s Audit log (Gear icon> Audit log). In the audit log window, the invoices you’ve changed would be tagged as Edited under the EVENT column. You can click the View link under History and select Compare at the upper right corner to view what information has been changed. In this page, you’ll also know the original invoice details prior from editing it.

Moreover, you can share your preferred way of tracking this information with our developers through feedback. Just click the Gear icon at the top and select Feedback.

Keep posting your questions every time you have further concerns about QuickBooks.
