Five sessions on the paperwork that keeps a business honest — and its limits.
Your student journalises the same eight March transactions from the previous unit, posts them to ledger accounts, and proves a trial balance that foots to $14,390.
Then the books are deliberately broken. Five planted errors, and your student hunts them — only to find that two of them leave the trial balance perfectly balanced and completely wrong.
That discovery is the unit. A trial balance proves the two sides are equal. It does not prove they are right.
