I'm here to help you, Paul.
Before we move forward, could you please provide me with a screenshot of the error message you’re seeing about the incorrect invoice date? This will help me better understand the situation and get to the root of the issue.
QuickBooks allows invoices to be previewed, saved, and sent regardless of the date. The issue you’re experiencing may be related to how your browser is processing the information. Browser cache or outdated data can cause conflicts that result in unexpected errors.
To address this, let's begin by clearing your browser's cache. This will refresh the connection to QuickBooks and eliminate any temporary issues affecting the functionality. You can also use another supported browser.
Please let us know if you have further questions.
