Thanks for updating us, @ste36.
To isolate the issue, let's first make sure that your QuickBooks Desktop (QBDT) program is updated to its latest release. This will keep your system having updated components that fix common issues.
Once done, resend an invoice again. Make sure to uncheck the Print Status Stamp box as outlined in the steps shared by MariaSoledadG.
However, if the issue persists, I recommend contacting our Technical support team to further review your set-up and determine why you are still seeing the due date in the email. To do so, please follow the steps provided by JenoP.
Also, to control what information your customer sees when sending their invoices, feel free to personalize your sales templates. For the detailed guide, check out this article: Use and customize form templates.
If there's anything else I can do to help you ensure that no due date appears when you email an invoice, please post a response below. I am always available to lend you a hand. Have a good one.
