Maintenance and residents — in one place.

Dispatch technicians, keep residents informed, and track every repair from request to paid invoice without spreadsheets or endless phone calls. Common-charge billing can be modelled as recurring charges per apartment, but Nineflat is not a dedicated κοινόχρηστα ledger today.

• Residents report issues from their phone with photos; you assign a technician; the loop closes automatically.
• Recurring charges per apartment let you bill any monthly amount (rent, common-charge contribution) and track who has paid.
• Per-property maintenance cost history — see the audit trail when a resident asks.
