INDUSTRY REALITY

The cost of inefficiencyfor a 100-unit property manager

You feel like you spend your day chasing information. It's not a question of organisation. It's the structural cost of fragmented management.

0h
per week lost managing what your tenants could handle themselves
0h
recoverable per day once your tenants have their own portal
0€
billed to your organisation in operational inefficiency per year

Calculation: 100-unit manager · €45/h gross · 15h/week inefficient. Source: Federia/IPI. Conservative estimate, some agencies report 20h/week.

How SEIDO reduces that cost

SEIDO handles coordination. You handle management.

Triage, track, and route every request without manually relaying between your contacts.

The combination your current tools don't offer.

5 channels. One queue.

WhatsApp, email, SMS, calls, app: triaged by urgency, turned into an intervention.

Three portals. Fewer calls, more autonomy.

Each party acts in their own space, without going through you.

Real-time tracking, like a parcel.

Manager, provider, tenant: everyone sees the status.

An assistant that handles requests.

It triages, prioritises and executes low-risk actions. You oversee more units, without hiring.

And everything else is already here.

No integration. No extra tool.

Any document in 10 seconds

Leases, EPC, photos. Filed by property, searchable from mobile.

Contacts and history

Your connected banks, one screen

Receipts, costs, cash flow: full overview.

Signed. Archived. Findable.
