I open my mail at my desk where I immediately throw all envelopes from the opened, junk mail, etc into the trash. I tear off my payment stub and lay it in the flap of the payment envelope (so I can see what is due and when). I then put it in order by due date if I have any other bills and place it in a file folder to be paid. I put my portion of any mail into 1 of 2 other file folders: 1 is for tax deductible receipts and the other for misc bills such as utility, etc. Then when it's time to pay bills, everything is in order and ready to be paid. You could also go so far as to stamp your return address on the envelopes if time permits.
