Future invoice date as future SEND date
Because the recurring invoices must all have the same preferences, I use recurring invoices for automatic payments and have invoices to be sent automatically setup as drafts to be sent later. I believe this is the best option and probably what most people are doing, but let me know if I am incorrect.
There are a few default option for future date to send. The invoice date should be one.
Also there should be a preference not to send email notification on weekends, business days only. But this is not as important.
