the record

Treasury sees everything, reconciles nothing by hand.

Accounts and rails across banks, currencies, and markets — one consistent record, continuously updated, where every movement is attributable.

/01Unified balancesEvery account, every currency, every market in one view — with available and pending clearly separated. Value in motion is visible, not invisible.
/02Reconciliation without manual workDeclare expected payments; Onzo matches arrivals automatically — reference, counterparty, and amount with configurable tolerance. Unmatched funds surface immediately. Nothing disappears into suspense.
/03Returns, modeled honestlyPayments come back — wrong details, closed accounts. Returns are first-class objects tied to their original payment, closing the loop in the record automatically.
/04An audit trail by constructionEvery ledger entry is attributable to a payment, return, or conversion. Export-ready, timestamped, complete — evidence, not assurances.
