Source Documents and Books of Original Entry
A business transaction should leave evidence. Source documents provide the original evidence from which accounting records are prepared. In KCSE, the key skill is to follow the full chain: transaction → source document → book of original entry → ledger account.
Stage 2
Comprehend
Build the core concepts, explanations and evidence.
Source documents
Common source documents include invoices, receipts, credit notes, debit notes, statements of account, payment vouchers and petty-cash vouchers. An invoice records an amount due, commonly following a credit sale. A receipt acknowledges money received. A credit note normally reduces an amount previously charged by a seller, for example after goods are returned or an overcharge is corrected. A debit note may be sent by a buyer to a supplier to notify the supplier of a debit, such as returns outward. For every document ask four questions: who prepares it, who receives it, which transaction it proves, and which accounting record receives its information.
Books of original entry
Books of original entry are the first systematic accounting records prepared from source documents before ledger posting. Credit sales of goods go to the sales journal; credit purchases of goods to the purchases journal; returns inward to the returns inward journal; returns outward to the returns outward journal. Transactions that do not belong in a specialized journal may be entered in the general journal. Cash and bank transactions are recorded through the cash book, while small repetitive payments may be controlled using a petty cash book where that system is used.
Recording and posting
Suppose Kamau Traders sells goods on credit to Amina Stores for KES 24,000. The invoice supports the transaction. The sales journal records Amina Stores and KES 24,000. Posting then debits Amina Stores' account and credits Sales. If Amina returns goods worth KES 2,500, the returns inward journal records the return; posting debits Returns Inwards and credits Amina Stores. This sequence tests whether you can move correctly from evidence to journal to ledger without reversing the accounting effect.
Stage 3
Apply & check
Test understanding and surface misconceptions early.
Worked sequence: Jirani Supplies buys goods on credit from Mwangaza Wholesalers for KES 60,000, returns damaged goods worth KES 5,000, then pays the balance through the bank. The purchase is supported by the supplier invoice and entered in the purchases journal. The return is entered in the returns outward journal. The remaining amount payable is KES 55,000 before any other adjustments. The bank payment is recorded in the cash book and posted to the supplier's account.
❓ CHECK YOUR UNDERSTANDING
Checkpoint: A trader sells goods on credit, receives returned goods from the customer, then receives payment. Identify the source document and book of original entry for each stage and state the ledger effect.

💡 NOTE
Misconception alert: an invoice is not evidence that cash was paid. It records an amount charged or due; a receipt acknowledges payment received.
Stage 4
Extend
Deepen learning through mastery practice, reflection and teacher-ready application.
❓ CHECK YOUR UNDERSTANDING
KCSE-style original practice: From a list of credit purchases, credit sales, returns inward and returns outward, prepare the appropriate journals and post the entries to the relevant ledger accounts. Award marks for correct journal selection, correct amounts and correct debit/credit posting.
This question is for reflection. No automatic marking is configured.
📋 ACTIVITY
Teacher OS: display sample transaction documents, let learners classify them, model one journal entry and ledger posting, then run a misconception check on invoice versus receipt before independent KCSE-style practice.
📋 ACTIVITY
Student OS: create a four-column revision table headed Transaction, Source document, Book of original entry and Ledger effect. Fill it without notes, then correct errors using this chapter.
