Reverse anything. Everything it touched fixes itself
Payroll, loans, bills, invoices, petty cash and tax challans all settle into the same ledger — so undoing one is undoing all of it, correctly. Reverse a payroll payment and the run, the bank balance and the payslip all correct themselves in one motion. A cheque stays pending until it actually clears, so the number on screen is the number you actually have — across multiple accounts and currencies, reconciled against the real statement.
