An operating system for your financial department
Onefin brings ownership, assets, debt and cash into one comprehensive cash management and treasury platform — built for corporate groups and real estate companies. Connect every source, manage every position, and report with confidence from a single source of truth.
A comprehensive overview of ownership, assets, debt and cash
Seven modules, one platform. Each is built on live data so the numbers are always current — and always reconcilable to source.
Companies
Keep a comprehensive overview of your organisational chart and KYC data for every company you manage. Stay up to date on ownership, shareholder structure and registrations, and create a single source of truth for collaboration and reporting.
Banking
Manage all your banking activity in one platform. Sync real-time bank accounts, search transactions and monitor cash flows across +1500 European banks, and initiate internal transfers within your group — a modern alternative to a corporate cash pool, set up in minutes.
Assets
Get a comprehensive overview of your real estate assets and maximise their value. Access market valuations, track property data and analyse investment opportunities — then model scenarios for long-term forecasts and optimise your portfolio.
Debt
Take control of your financial risk with the treasury module. Manage loans, swaps, derivatives, bonds and collateral in a structured ledger, and stay on top of market interest rates for proactive decision-making.
Cash forecast
Combine upcoming payments for taxes, invoices and loan repayments to model a 360° view of your future cash position across subsidiaries. Get early warnings on negative balances and transfer funds proactively.
Tax
Manage all your tax data in one place — upcoming taxes and historical payments alike. Build custom bookkeeping templates to reconcile and book transactions from multiple tax accounts at once.
ESG
Prioritise sustainability and ESG compliance across your portfolio. Access ESG data to identify properties that qualify for green financing, stay aligned with industry standards, and report traceable data to counterparts to reduce interest-rate costs.
Three solutions, one platform
The modules come together into three solutions that map to how a corporate finance team actually works — governing the group, managing its liquidity, and controlling its risk.
Governance
Navigate complex decision-making structures while keeping transparency and compliance. Get an intuitive view of ownership and subsidiaries, track property data and ESG performance, and stay compliant on KYC and covenant reporting.
Liquidity Management
See exactly where your group’s cash sits. Sync balances in real time across +1500 European banks, analyse transactions and cash positioning, make in-group transfers, and stay ahead of upcoming taxes — all from one platform.
Risk Management
Keep a complete ledger of debt and collateral for reconciliation, forecast market rates and interest-rate costs, and report with a full IFRS suite on debt-related accounting notes — with daily rates for STIBOR, NIBOR, CIBOR, SONIA and SWESTR.
Unifying financial data from different sources, seamlessly
Connectivity is at the core of our value proposition. Onefin refines financial data in three stages — connect it from source, manage it in one ledger, and evaluate it with confidence. Say goodbye to manual data entry, duplicate effort and data trapped in silos.
Connect seamlessly to every source
Link directly to your sources for financial data — bank accounts, tax accounts, invoicing systems and market data. Onefin facilitates the secure, efficient exchange of financial data so you can consolidate information from multiple sources into one unified view.
Connected to the data sources you already rely on
Onefin pulls directly from public registers, banks, tax authorities and ERP systems — so your platform reflects reality without manual lookups.
