i have seen net 0 terms before. maybe that was why

thanks for the insight. I guess it makes sense then to remove the credit limit if there are no terms as it implies payments taken when orders are created. And for it to be Cash Sale, we'd need to set the payment method on the order?

I've seen NS natively create cash sales from SOs without setting the payment method on the sales order, but maybe it was something about the form they were using
