Your entire location portfolio
in one overview.
Rentarion extracts leases automatically, calculates termination periods with statutory reference-date logic §573 BGB, and makes indexed rent adjustments visible — before they hit your invoice.
Everyday life without a central system
Contracts in folders, nobody has an overview
At 50, 100 or 200 locations, manual upkeep becomes a source of error. Every missed deadline and every overlooked indexation costs real money.
Reference-date logic by hand
"6 months to quarter end with lease end 15 Aug 2027" — what does that mean in concrete calendar terms? Answering this in your head produces errors. A miscalculated deadline can mean 5 more years of lease.
Adjustments missed
CPI-linked rents rise regularly — whoever doesn't notice the adjustment pays higher costs for a long time without complaint. Across 50 locations, this adds up to six figures over the lease term.
Special termination rights hidden
Revenue decline exits, break clauses after 5 years, special termination rights on site changes — buried in contracts, forgotten at decision time. One unused break clause = multiple years of forced rent.
No comparative view
Which locations are above €25/m²? Which expire in 2027? Which to terminate, which to keep? Without a central view, you make decisions blindly.
Location managers don't upload
New contracts end up on local managers' desks, portfolio management has patchy visibility. Without a simple upload flow and clear roles, this remains a permanent problem.
Nine features that make the difference
From folders to portfolio dashboard
All key data captured automatically, every deadline calculated, questions in natural language — in under a minute per contract.
Termination dates with reference-date logic
Engine calculates the exact termination date from lease end + notice period + reference date (month end / quarter end / half-year end / year end). Forward calculation for past dates.
Indexed rent + mixed clause detection
Engine detects index clauses, calculates next adjustment, warns on trigger. Special case §557a (3) (stepped + indexed): invalid mixed clauses are flagged — you don't pay on a wrong basis.
Special termination rights surfaced
Break clauses, break-clause dates and notice periods, revenue-decline exits — all as actionable deadlines in the dashboard, with reminders 6 months ahead.
Portfolio comparison
Locations with remaining term (color-coded), total rent, risk level, next critical deadline — grouped by city or region on demand: Munich vs. Berlin per m², deviation from the portfolio average at a glance.
Rent optimisation radar
Where do you pay above market — and when is the negotiation window open? The radar combines €/m² comparison (market + portfolio average), termination and renewal deadlines and rent-to-revenue ratio into a prioritised list per location — including a dossier PDF for the negotiation meeting.
AI Portfolio Chat
Natural language: "Which of my 87 locations expire in 2027?" — "Which contracts are above €25/m²?" — answer in seconds. Nothing is stored — GDPR-compliant.
Multi-location + roles
Branch managers upload locally (portfolio-manager role), C-level sees everything (admin), four-eyes principle for critical fields (approver). Clear processes, no back-and-forth.
Bulk CSV import
Migrate existing portfolios in hours — even with 200+ locations. Automatic column mapping, guided import assistant, partial success instead of all-or-nothing.
Excel · PDF · iCal
Portfolio Excel with active filters (status/city/risk), PDF report for leadership, iCal export of deadlines for Outlook/Apple Calendar — directly integrated.

How the engine calculates
Three concrete examples
What people do by hand, the engine does in milliseconds — and verifies every quote against the original contract.
Fixed-term lease → termination
Lease end 15 Aug 2027, notice 6 months to quarter end. Engine finds last reference date ≤ lease end (30 Jun 2027), minus 6 months → you must terminate by 31 Dec 2026.
Next adjustment calculated
Index clause tied to CPI, base 1 Jan 2024, interval 12 months. Next adjustment 1 Jul 2026. Estimated increase at CPI trend 2.8% ≈ 3.2%. You know it six months ahead.
Revenue-decline exit
Contract: "If revenue declines >20% between Q1 and Q3, terminable with 3 months notice to quarter end." Engine extracts the condition and sets a conditional deadline — with a reminder once relevant.
