This channel is used by condominium property managers. In order to save on operating costs, they choose to have all the documents delivered to the caretaker of the building. The latter then deposits the mail in the letterboxes of the addressees. The mails are sorted by name in the parcel.
This channel is also used within companies for which we print their employees' pay slips. We send a parcel with unsealed envelopes. The managers can then add the Ticket Restaurant to the envelopes before distributing them to the employees. Documents are sorted by activity (Management/R&D/Support/Finance...) and by name in the parcels.
