Business Documents and Books of Prime Entry

Every transaction starts life as a paper (or digital) document. Before anything reaches the ledger, it’s first listed in a “book of prime entry” — a chronological log specific to one type of transaction.

1. Key Business Documents

Document	Purpose
Invoice	Sent by the seller, requesting payment for goods/services supplied on credit
Debit note	Sent to confirm/request a reduction (e.g. faulty goods being returned)
Credit note	Sent by the seller, confirming a reduction in the amount owed
Statement of account	Summary of all invoices, payments and credit notes for a period
Receipt	Proof that a payment has been received
Bank statement	Record of transactions through a bank account, issued by the bank

Worked example — trade discount on an invoice Goods with a list price of $200 are sold with a 10% trade discount. Calculate the net invoice amount.
Trade discount = 200 × 10% = $20. Net amount = 200 − 20 = $180 (trade discount is deducted before the invoice total — it is never entered in the accounts separately).

2. Books of Prime Entry

Book	Records
Cash book	Cash and bank receipts/payments (often a 3-column format: discount, cash, bank)
Petty cash book	Small cash payments (using the imprest system)
Sales/Purchases journal	Credit sales/purchases of goods
Sales/Purchases returns journal	Goods returned by customers/to suppliers
General journal	Any transaction not covered by the other books (e.g. correcting errors, opening entries)

Worked example — the imprest system A petty cashier is given a $100 float (the imprest amount). During the month, $73 is spent on small expenses. How much is the cashier reimbursed at the end of the month, and why?
The cashier is reimbursed exactly $73 — the amount spent — so the float is restored back to the fixed imprest amount of $100 ready for the next period.

Common mistakes to watch for

Confusing trade discount (deducted before the invoice, never recorded separately) with cash discount (recorded in the discount columns of the cash book, for early payment).
Mixing up a debit note and a credit note — the seller issues the credit note, formally reducing what’s owed.
Forgetting the reimbursement in an imprest system always restores the float to its FIXED starting amount, not to a new arbitrary figure.

Key Vocabulary Recap

Trade discount — a reduction off the list price, deducted before the invoice total

Cash discount — a reduction offered for prompt payment

Imprest system — a petty cash system where the float is restored to a fixed amount each period

Business Documents and Books of Prime Entry — Practice: Solutions

Purpose of an invoice.

✓An invoice is sent by the seller to the buyer, requesting payment for goods or services supplied on credit, and detailing quantities, prices, and any trade discount.

Debit note vs credit note.

✓A debit note is sent (often by the buyer) to request or confirm a reduction, e.g. when returning faulty goods. A credit note is then issued by the seller, formally confirming the reduction in the amount owed.

List price $400, 15% trade discount.

Trade discount = 400×15%

400×0.15=60

✓Net amount = 400−60 = $340

Trade discount vs cash discount.

✓Trade discount is a reduction off the list price (e.g. for bulk buyers), deducted before the invoice total is calculated, and is never recorded separately in the accounts. Cash discount is offered as an incentive for prompt payment, and is recorded separately in the discount columns of the cash book.

Books for credit sale and supplier return.

✓(a) Sales journal (b) Purchases returns journal

Book for an error correction.

✓The general journal

Float $150, spent $112. Find reimbursement.

✓Reimbursed $112 (the amount spent), restoring the float back to the fixed imprest amount of $150 for the next period.

Explain the imprest system.

✓The petty cashier starts each period with a fixed float (the imprest amount). At the end of the period, the total spent is reimbursed exactly, restoring the float back to the same fixed starting amount for the next period.

Purpose of a bank statement.

✓A bank statement is issued by the bank, showing all transactions (receipts and payments) through a business’s bank account, and the resulting balance — used to check against the business’s own cash book.

Q10

Manual vs digital recording.

✓Any valid comparison, e.g. digital records reduce arithmetic errors (automatic calculation) and are faster to search, while manual records don’t rely on technology or internet access but are more prone to human error and slower to process.
