I pay my bills the old fashioned way, by mail. To save time, I "prep" them as soon as they are brought into the house from the mailbox.
I discard the envelope they arrive in, as well as any extraneous paperwork like flyers & inserts. I stamp the return envelope & put my address label in the upper left corner. Then I put everything into my Bills To Pay folder. When I'm ready to sit down & write my checks, everything is ready for me.
