A history that stays with the building
Correspondence can stay attached to the condominium instead of being scattered across personal inboxes.
Clear follow-through
The aim is to give each request an owner and a next step, helping prevent missed messages and duplicate replies.
Documents in context
Invoices can reach the correct building and be reviewed before being recorded or shared with authorised people.
Planned workflow, not yet available as a complete service. Receiving an invoice does not approve or pay it. Staff will manage the inbox; private messages will not be shared with every resident.
Personal access. Human support.
