Is anyone having trouble with the invoice due date changing to an earlier date?

It's our priority to ensure that you'll be using the correct due date in the invoice, jbmcall. 

Let's perform some basic troubleshooting steps to make sure the issue isn’t browser-related. It’s possible that local internet cache files are the reason for this unexpected behavior. 

Let's start accessing your account using a different or private browser. You can use either of these shortcut keys:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Shift + N

Once in, try copying the invoice again.  If it works, go back to your regular browser and clear its cache. This is done to speed up the process the next time you do a transaction in QuickBooks Online. Also, an alternative way is to use other compatible browsers.

Thank you for your attention to my question. I was able to find the problem but it did not have anything to do with the browser. This is how i fixed it:

In settings, went to "all lists"

Selected "terms"

Clicked on the dropdown arrow for "Due on receipt"

Found that the setting was for the 1st of the month (due on a certain day of the month) which was not what i wanted .

Selected "Due in fixed number of days" and chose "0".

Now my invoice due date matches the invoice date which is what i wanted for "due on receipt".

I am unable to send past due invoices at all - continue to get error message that says:

'You must specify a valid due date.'

Our invoices are Due on Receipt and I have already checked the settings on this so that "Due in fixed number of days" is set to "0".

I am using our old template - is this the problem?

I tried sending invoices with a Due on receipt term and I was able to email it successfully. 

This error might be caused by too much cache or an issue in the browser that you're using. I have steps to share that can resolve some of the most common browser and unexpected results when working in the program.

Let's start by switching or using other browsers like Google Chrome, Mozilla, Microsoft Edge, or Safari. They are all compatible with QBO and can help us isolate the issue. Use these keyboard shortcuts on how to do that:

• Ctrl + Shift + N for Google Chrome
• Ctrl + Shift + P for Firefox
• Control + Option +P if you're using Safari
• Ctrl + Shift + P for Microsoft Edge

After that, try to email an invoice to check if the error is no longer there. If everything is working fine,  follow the steps in this article on how to clear cached or delete internet files; Clear Cache and Cookies to Fix Issues When Using QuickBooks Online.

The Community is always here if you need anything else. 

Clearing the cache was not the problem.  A QB phone representative confirmed that this date problem is a known coding error related to the new invoice template that will be fixed in the next release.  For now, I temporarily switched back to using the old template which allows me to set the invoice due date earlier than the invoice date.
