I just signed-up for paper billing, which costs $5.00 a month, because I don't like auto-pay. I was installed on March 1, 2016. When do I receive a paper bill and when is my payment due?
That payment you made not long ago actually covers you until April (so yes, upfront for March). You won't get another bill until April 1 so you don't need to worry about owing anything this month! April's paper bill should say Services from April 1 - May 1
The bill you get on April 1 is not due until May 1 since you are on paper billing, so it doesn't necessarily need to be paid April 1. Hope that answers your question :)
