Purchase Journal Entry – A First Look
Think of a shopkeeper who buys goods to sell. Every time they bring stock into the shop, something changes: the shop now has more goods, but it also owes money (or has paid cash). The purchase journal entry is simply the accountant’s way of recording that moment — the moment goods come in.
The Everyday Intuition
You walk into a stationery shop and buy 50 notebooks for ₹2,000. From the shop’s point of view, two things happen at once:
- The shop gains notebooks (an asset).
- The shop loses cash (another asset) or owes the supplier (a liability).
The purchase entry captures both sides of that single transaction. It is not about the sale to a customer — that comes later. This is the inward movement of goods meant for resale.
The Precise Meaning
In Accountancy, a Purchase Journal Entry records the credit purchase of goods (stock-in-trade) for resale in the normal course of business. If the purchase is for cash, it goes into the Cash Book, not the Purchase Journal. The Purchase Journal (also called the Purchase Book) is specifically for credit purchases of goods.
Only goods bought for resale are recorded here. Buying a computer for office use, or buying raw materials for manufacturing, is not a “purchase” in this sense — those are asset purchases and go elsewhere.
Why It Matters
Without this entry, the business would not know:
- How much stock it holds.
- How much it owes to each supplier.
- The true cost of goods sold when calculating profit.
The Purchase Journal is the first step in the trading account. If you get this entry wrong, the entire profit figure goes wrong.
Accounting Treatment – The Golden Rule
For a credit purchase of goods, the rule is:
Debit Purchases Account (increase in expenses/goods)
Credit Supplier’s Personal Account (increase in liability)
The logic: Purchases is a nominal account (expense), so an increase is debited. The supplier is a personal account — when we owe them, we credit.
Example
On 5th April, bought goods from Ramesh for ₹10,000 on credit.
Journal Entry:
| Date | Particulars | L.F. | Debit (₹) | Credit (₹) |
|---|
| 2024 Apr 5 | Purchases A/c Dr. | | 10,000 | |
| To Ramesh A/c | | | 10,000 |
| (Being goods bought on credit from Ramesh) | | | |
The narration “Being goods bought on credit from Ramesh” is mandatory in the journal. It explains the transaction in plain words.
If It Were a Cash Purchase
If the same goods were bought for cash, the entry would be:
| Date | Particulars | L.F. | Debit (₹) | Credit (₹) |
|---|
| 2024 Apr 5 | Purchases A/c Dr. | | 10,000 | |
| To Cash A/c | | | 10,000 |
| (Being goods bought for cash) | | | |
Notice: the credit side changes from a personal account (Ramesh) to a real account (Cash). The debit remains the same because the nature of the transaction — gaining goods — is unchanged.
The Purchase Book Format (Proforma)
The Purchase Journal itself (the book of original entry) has a standard format. Each credit purchase is recorded here before being posted to the ledger.
Purchase Book (Journal) Format:
| Date | Invoice No. | Name of Supplier | L.F. | Amount (₹) |
|---|
| 2024 Apr 5 | 101 | Ramesh | | 10,000 |
| 2024 Apr 12 | 108 | Suresh & Co. | | 25,000 |
| | Total | | 35,000 |
The Purchase Book is totalled periodically (usually monthly). That total is then posted to the debit of Purchases Account in the ledger. The individual amounts are posted to the credit of each supplier’s account.
A Common Mistake to Avoid
Students often debit the supplier and credit purchases. That is backwards. Remember: the business is receiving goods (debit what comes in) and creating an obligation to pay (credit the giver). The supplier is the giver — they get the credit.
Never record a cash purchase in the Purchase Journal. Cash purchases go directly into the Cash Book. The Purchase Journal is only for credit purchases of goods.
The Bigger Picture
This entry feeds into the Trading Account at year-end. The Purchases Account balance (after adjusting for returns and closing stock) becomes part of Cost of Goods Sold. So the humble purchase entry is the foundation of the entire profit calculation.
Start with this: every time goods come in on credit, debit Purchases, credit the supplier. That single rule will carry you through dozens of variations — returns, discounts, trade discounts, and GST — all of which build on this basic structure.
