ZenTreasury is the financial contract accounting subledger for the Office of the CFO. Group controllers, CFOs, treasury managers, and auditors all work from the same contract data, because the ERP that posts the journal entry does not know the contract behind it. Add a lease once and ZenTreasury generates the right of use asset, the liability, and the full period by period schedule automatically, with depreciation, interest, and balance carry forward following the standard from day one. Index-linked remeasurement is handled automatically: index rates, base values, applied dates, and next indexation dates are tracked per contract and applied on schedule. Every modification, including scope changes, term extensions, rate revisions, and partial terminations, triggers a recalculation and is logged with a timestamp and user, so the before and after picture is always there without a follow up request. On the treasury side, ZenTreasury centralises FX position management (forwards, swaps, cross currency instruments with mark-to-market), internal and external loan and money market tracking with DCF valuation against yield curves and automated interest calculations, trade finance and guarantee monitoring with fee and exposure tracking, and group wide cash flow forecasting with scenario modelling. All multi entity, multi currency, with a complete per-field audit trail and direct bank connectivity. Every customer gets a dedicated, isolated database, so lease and treasury data is never shared with other tenants. This is a meaningful differentiator for enterprise audit and GDPR requirements. Multi entity, multi currency, SSO (Azure, Entra, Google, Microsoft 365), MFA, and role-based access are all included. It is one platform, not a bundle of modules: accounting is included, and pricing scales to the contracts, entities, and users you actually run. Lease calculations are independently reviewed by an international audit firm. Connect Claude, ChatGPT, or any MCP client
