The due date is not changing with the terms of payment. For example Net 30 days for payment has no affect on the due date

Hello Northerngardensu,

There is a known issue occurring on several companies involving the Terms field, which we are currently investigating.

At present, you may need to use the workaround of changing the Due Date manually on transactions.

In addition, if you could contact our support team, we can add you to the list of those companies to be checked, and notified when the issue is resolved:

1. Log into QuickBooks Online
2. Select Help
3. Select Contact Us
4. Type in your inquiry and select Let's Talk
