What this dot point is asking
A real business has too many transactions to journalise each one separately in the general journal. Unit 2 introduces special journals, which sort similar transactions together, and subsidiary ledgers, which track the detail behind a single control account. Together they make a manual system fast and self-checking.
The four special journals
- Cash Receipts Journal: every transaction where cash comes in (cash sales, receipts from debtors, capital, loans).
- Cash Payments Journal: every transaction where cash goes out (cash purchases, payments to creditors, expenses, drawings).
- Sales Journal: credit sales of goods only.
- Purchases Journal: credit purchases of goods only.
Anything that does not fit (for example, depreciation or correcting entries) still goes in the general journal. The advantage is that each journal is totalled at the end of the period and posted to the general ledger in one figure per column, saving enormous effort.
Control accounts and subsidiary ledgers
The general ledger keeps a single Debtors Control account and a single Creditors Control account. The detail behind them lives in subsidiary ledgers: the debtors subsidiary ledger has one account per customer, and the creditors subsidiary ledger has one account per supplier.
How posting works
Special journal totals post to the general ledger control accounts. The individual amounts post to the subsidiary ledger accounts. Because the same figures feed both, the subsidiary ledger total acts as a cross-check on the control account.
Worked example
Why this matters
Special journals and control accounts are the backbone of a manual recording system and the logic behind how accounting software organises data internally. Exam tasks frequently ask you to total a special journal, post it correctly, and prove that the subsidiary ledger reconciles to the control account.
