Use the result well

A clear answer, with the assumptions visible

These recommendations turn the result into an operational next step without hiding the inputs behind a score.

  1. 1

    Compare every row with bookings, payments, and refunds.

  2. 2

    Check package expiry and non-refundable credit rules separately.

  3. 3

    Protect the exported ledger as client financial information.

How this tool works

  1. Read each signed transaction as exact minor units.
  2. Add transactions in entered order to create a running balance.
  3. Flag the first row that would take the credit below zero.
