Questions

FAQ

  • Does Simon replace an accountant?
    No. Simon helps produce, review, and explain bookkeeping work, but it does not sign accounts and does not replace professional responsibility.
  • What is autonomous and what do I validate?
    Simon automates mechanical steps when data is sufficient. Sensitive decisions remain visible: ambiguous qualification, uncertain matching, tax filing status, closing choices, and result allocation.
  • What does free beta trial mean?
    The public pricing section is hidden during beta. The product is intended to be tried on a pilot company with a clear scope and your own configured AI provider.
