Differences from Firefly III

  • Use it with no server and no updates

    A ready-made service: nothing to install or update.

  • Tax builder

    Tax rules can be configured: profiles, tax for a period, obligations and a due date calendar.

  • What-if scenarios

    A scenario draft can be compared with the main scenario, applied or rolled back.

  • See your net worth months ahead

    The forecast shows income, recurring transactions, budgets and goals for up to 24 months.

  • Assistant

    You can set up budgets, taxes and payments in a conversation with the assistant and go through a report there too. Every change needs confirmation.
