A device (1) for conveying sheet documents between upstream and downstream sheet document processors is disclosed. The device (1) is independent from the upstream and downstream sheet document processors and comprises a receiving section (4) adapted to receive, in use, sheet documents discharged by the upstream sheet document processor into an output pocket of the upstream sheet document processor, and a transport (7, 8) extending from the receiving section (4) to an output section (26). The transport (7, 8) is adapted to convey sheet documents received at the receiving section (4) to the output section (26). The sheet documents are then discharged from the output section (26), in use, to the downstream sheet document processor. A corresponding method is also disclosed.
