Industry

FinTech and Payments

Payment products need operations that are safe to retry, reconciled continuously, and explainable when a customer disputes a transaction. Typical systems include payment APIs, ledgers, and reconciliation tooling.

Industry challenges

What makes this sector hard

  • Unsafe retries

    A retried request can double-charge because operations are not idempotent.

  • Manual reconciliation

    Reconciliation against the provider is a manual monthly exercise.

  • Unanswerable disputes

    Disputes cannot be answered from data.
