Portfolio Management

Everything in one place

Create properties and units, track occupancy, and keep your whole portfolio organized without spreadsheets. Pro plan adds unlimited Client Portfolios for clean per-client separation (one organization, many owners).

  • Unlimited property and unit creation
  • Occupancy and vacancy status at a glance
  • Unlimited Client Portfolios on Pro; multiple organizations on Enterprise

Billing & Rent Collection

Collect rent without the follow-up loop

Charges flow automatically from agreements. Accept payments online (Stripe) or record manual transfers (SEPA/IBAN, IRIS, cash). Collected rent settles to your bank account within 2 business days.

  • Automated recurring charge generation from agreements
  • Stripe online payments, SEPA/IBAN, and IRIS bank transfer
  • Manual payment recording for cash and cheque
  • 2-business-day payout with transparent fee breakdown

Agreements & Leases

The backbone of your billing

Agreements connect tenants and properties to your billing cycle. Set start/end dates, rent terms, and payment schedules. Nineflat tracks renewals and keeps a full party directory linked to each agreement.

  • Custom rent terms, start dates, and billing frequency
  • Expiry tracking and renewal alerts
  • Parties directory (tenants, vendors, co-owners) per agreement

Tenant Screening

Screen tenants before you sign

Vet a prospective tenant without ever touching their documents. You invite, they consent and upload their own files, and a report comes back — affordability assessed against the actual rent. An AI assistant coaches the applicant, but a human always decides. Available in Greece.

  • Tenant-led: you never handle raw payslips or IDs (GDPR-safe)
  • Affordability checked against the agreement's rent
  • Included quota by plan, then per-screening; free Rental Passport for tenants

E-Signatures

Sign the lease online, legally

Send a lease for signature and collect a legally-sound e-signature without leaving Nineflat — no DocuSign subscription. Every signature is captured with a tamper-evident audit trail and the signed PDF is stored against the agreement.

  • Built-in e-signature — no third-party tool to pay for
  • Audit trail on every signature: signer, timestamp, IP
  • Signed PDF stored on the agreement, ready to download

Co-ownership

Multiple owners, zero manual splitting

Define ownership percentages once. When a tenant pays, Nineflat automatically calculates and records each co-owner's share — no more bank transfer spreadsheets or manual math.

  • Unlimited co-owners per property with custom percentages
  • Automatic split calculation on every payment
  • Each co-owner sees their own share in their dashboard

Reminders & Automation

Never miss an obligation again

Set recurring reminders for expense settlements, maintenance inspections, or anything else that repeats. Nineflat emails all involved parties automatically — you configure it once and forget.

  • Recurring reminders for settlements and maintenance
  • Automated email delivery to all involved parties
  • Configurable schedule: weekly, monthly, quarterly, annual

Access & Permissions

The right view for every person

Staff get role-scoped access to the properties they manage. Tenants get invite-only portal access to their own invoices and balance. Everyone sees exactly what they need — nothing more.

  • Owner, portfolio manager, building manager, and tenant roles
  • Staff invites on Landlord plans and above
  • Tenants see their invoices, payment history, and open balance
