  1. 01

    AI-driven extraction

    A receipt becomes structured data — vendor, amount, date, category — in under three seconds. The user does nothing.

    Powers resume parsing, bill ingestion, and receipt prefill across the hiring, bookkeeping, and claims projects.

  2. 02

    Workflow with teeth

    Every state transition writes an audit row. The card you see is the source of truth — no shadow spreadsheets, no Slack threads.

    Powers claim approval, commission payouts, and finance change-requests across three internal apps.

  3. 03

    Multi-currency, done right

    The native currency, the rep's preferred currency, and the reporting currency are all stored — and all reconcilable, at any point in time.

    Powers the commission tracker — USD, SGD, KRW, THB — converting at approval time, not submission.

  4. 04

    Data as a network, not a table

    Business units, contracts, vendors — modelled as a graph. Hover any node and its neighbourhood lights up. Cost-attribution questions answered in a glance.

    Powers spend attribution in the finance workspace and the reconciliation graph in the bookkeeping pipeline.
