Systems and methods for an exit control mechanism indicating an incomplete packing state near an exit portion of a packing station. A control system determines a pack job and determines a pack plan for the pack job. The control system may send instructions to a pack station directing packing of the pack job in accordance with the pack plan. The control system may receive indications of packing progress, for example, electronic indications from a scanner at the pack station, and update the state of the pack job, such as incomplete or complete. The control system instructs an exit mechanism to change from indicating an incomplete pack state to indicating a completed pack state based on, for example, determinations that the steps of the pack plan have been completed correctly and that the pack job is complete.
