Thanks,

That worked for us but now I have a new question related to the above.
We adjusted the customers so that all the customers in the account set have the same terms as I was looking to do above but now when we create new customers the terms default to net 30 but for some account sets we would like it to default to 1st of the month.
I want to try to have this default so that we don't have to go through 2 settings and potentially miss one and then have to update everything again later when it gets all mixed again.

Just trying to prevent data entry errors.
