AI-assisted contract extraction reads PDFs and proposes lease terms with confidence scoring; you approve, and the deterministic engine handles the math. Same inputs, same outputs, every time. Includes a Discount Rate Advisor that pulls reference rates from central bank sources, plus continuous compliance monitoring for indexations and reassessments. Journal export to SAP, Oracle, Dynamics, and NetSuite. Free tier covers 2 leases, no card required; paid plans from €149 per month with no per-seat pricing.

ZenTreasury is the financial contract accounting subledger for lease and treasury, built for the Office of the CFO. Your ERP posts the entry. It doesn't know the contract behind it. ZenTreasury does.
Add a lease once and get the full schedule: right of use asset, liability, and period by period amortization generated automatically. Index-linked remeasurement is handled automatically. Every modification recalculates the schedule and keeps the per-field audit trail intact.
On the treasury side, manage FX positions, loans, guarantees, and group wide cash flow forecasting in the same platform, multi entity and multi currency by design.
One product, accounting included, priced to the scope you run. Every customer gets a dedicated, isolated database. Lease calculations are independently reviewed by an international audit firm. Connect your own AI, Claude, ChatGPT, or any MCP client, directly to your contract data.

It models operating cash flow, rent and expense growth, vacancy, debt, acquisition and disposition assumptions, lease rollover, scenarios, and sensitivities across multifamily, office, retail, industrial, hospitality, and other property types. The platform calculates NOI, cash flow, DSCR, IRR, equity multiple, cash-on-cash return, and valuation. Calculation detail makes outputs traceable to source documents and assumptions.
