I provide the specifics, by using the words you would see if you need to use QB Help to search on them, and the Steps you use. Updating a Customer's Terms now doesn't change their existing invoices; that's because this can be a change in the agreement between you and the customer going forward, and not an oversight on initial settings. Also, showing it to yourself or not, and showing it to the customer or not, are both options for you, the user, so that you get what you need, and others get what they need. And Showing it or not, Due Dates always exist, as you can see by running the AR Aging reports. The point of needing to control something = put it in your view, under your control, and/or instead of Manual management, take advantage of the Default management provided by the program. A computer will do the "calendar math" for you, if you take advantage of the function for assigning Default terms to clients. A lot of times, people do not come across this entire function and don't know what it is or how to use it, or how to Address that they overlooked it previously.
Text is Harsh.
In my Classroom, we get to do this together on computers with mine on the large TV. You only get Text over the internet. You don't get warm and fuzzies. Sorry.
