A closed loop postage metering system includes networked meters that provide mailers and/or recipients the capability to request additional or modified services during processing of a mail piece by a carrier. The networked meter allows the Post to charge the mailer, or even the recipient for these services or to provide them with a refund or credit. The services can include changing the processing of the mail piece. Further the closed loop postage metering , system enables more precise methods of paying for services when multiple carriers handle a mail piece. A special case of such multiple carriers handling is the handling of international mail.
