Sales & Purchase Transactions: Records, Journals & Control Accounts

TAKEAWAYS:

• Sales/purchase transactions are recorded in journals (Sales/Purchase Day Book) before posting to ledgers, ensuring accuracy and traceability.
• Cash vs. credit transactions differ in timing (immediate vs. deferred payment) and journal treatment (e.g., "Cash A/c Dr" vs. "Debtors A/c Dr").
• Control accounts (Sales Ledger Control, Purchase Ledger Control) summarize individual customer/supplier balances for efficiency.
• Discounts (trade vs. cash) affect profit margins and are recorded separately in discount accounts.
• Returns (sales/purchase) are contra entries that reduce revenue/expenses and require reversal entries.
• Bank reconciliation for sales/purchase transactions resolves discrepancies between books and bank statements (e.g., unpresented cheques, bank charges).

1. Definitions and Classification

Sales and purchase transactions are the core revenue-generating and cost-incurring activities of a business. They can be classified into two types based on payment timing:

Types of Transactions

    class Transaction {
        +Type: Cash/Credit
        +Direction: Sales/Purchases
        +Journal: Day Book or General Journal
    }
    class CashTransaction {
        +Payment: Immediate
        +Journal Entry: Debit Cash A/c
    }
    class CreditTransaction {
        +Payment: Deferred (e.g., 30/60 days)
        +Journal Entry: Debit Debtors/Creditors A/c
    }

    Transaction <|-- CreditTransaction

Key Terms:

• Sales Transaction: Transfer of goods/services to customers for revenue. Example: Daraz selling a laptop to a customer in Kathmandu.
• Purchase Transaction: Acquisition of goods/services for resale or business use. Example: A local grocery store buying rice from a wholesaler.
• Cash Transaction: Payment/receipt is immediate (e.g., cash, cheque, digital payment via Khalti/eSewa).
• Credit Transaction: Payment/receipt is deferred (e.g., "30 days credit" from a supplier).

2. Recording Sales Transactions

Sales transactions are recorded in the Sales Day Book (for credit sales) or Cash Book (for cash sales). Below is the journal treatment for both:

A. Cash Sales

When goods are sold for cash (e.g., a street vendor selling samosas):

| Date       | Particulars                     | L.F. | Dr (Rs.) | Cr (Rs.) |
|------------|----------------------------------|------|----------|----------|
| 2079/Chaitra/1 | Cash A/c                          |      | 50,000   |          |
|            |   To Sales A/c                   |      |          | 50,000   |
|            |   (Cash sales of Rs. 50,000)      |      |          |          |

B. Credit Sales

When goods are sold on credit (e.g., a retailer selling to a wholesaler):

| Date       | Particulars                     | L.F. | Dr (Rs.) | Cr (Rs.) |
|------------|----------------------------------|------|----------|----------|
| 2079/Chaitra/1 | Debtors A/c (Gurung Store)      |      | 300,000  |          |
|            |   To Sales A/c                   |      |          | 300,000  |
|            |   (Credit sales to Gurung Store) |      |          |          |

C. Sales Returns (Contra Entry)

If a customer returns goods (e.g., a defective fan sold to Saru Brothers):

| Date       | Particulars                     | L.F. | Dr (Rs.) | Cr (Rs.) |
|------------|----------------------------------|------|----------|----------|
| 2079/Chaitra/10 | Sales Returns A/c               |      | 15,000   |          |
|            |   To Debtors A/c (Saru Brothers) |      |          | 15,000   |
|            |   (Goods returned by Saru Brothers) |      |          |          |

3. Recording Purchase Transactions

Purchases are recorded in the Purchase Day Book (for credit purchases) or Cash Book (for cash purchases).

A. Cash Purchases

Example: A shopkeeper buys inventory for cash:

| Date       | Particulars                     | L.F. | Dr (Rs.) | Cr (Rs.) |
|------------|----------------------------------|------|----------|----------|
| 2079/Chaitra/5 | Purchases A/c                    |      | 40,000   |          |
|            |   To Cash A/c                    |      |          | 40,000   |
|            |   (Cash purchase of goods)      |      |          |          |

B. Credit Purchases

Example: A retailer buys goods from a supplier on credit:

| Date       | Particulars                     | L.F. | Dr (Rs.) | Cr (Rs.) |
|------------|----------------------------------|------|----------|----------|
| 2079/Chaitra/3 | Creditors A/c (Nepal Wholesalers)|      | 80,000   |          |
|            |   To Purchases A/c               |      |          | 80,000   |
|            |   (Credit purchase from Nepal Wholesalers) |      |          |          |

C. Purchase Returns

If goods are returned to the supplier (e.g., damaged inventory):

| Date       | Particulars                     | L.F. | Dr (Rs.) | Cr (Rs.) |
|------------|----------------------------------|------|----------|----------|
| 2079/Chaitra/8 | Creditors A/c (Nepal Wholesalers)|      |          | 5,000    |
|            |   To Purchase Returns A/c        |      | 5,000    |          |
|            |   (Goods returned to supplier)   |      |          |          |

4. Discounts in Sales/Purchase Transactions

Discounts reduce the final amount payable/receivable. There are two types:

A. Trade Discount (Not Recorded in Books)

• Given for bulk purchases (e.g., 10% off for buying 100 units).
• Not journalized; only the net amount is recorded. Example: Buying 100 fans at Rs. 1,500 each with a 10% trade discount. Amount recorded: Rs. 1,500 × 90 = Rs. 1,350 per fan.

B. Cash Discount (Recorded in Books)

• Given for early payment (e.g., "2/10, net 30" = 2% discount if paid within 10 days).
• Recorded in Discount Allowed A/c (for sales) or Discount Received A/c (for purchases).

Example: Cash Discount Allowed

| Date       | Particulars                     | L.F. | Dr (Rs.) | Cr (Rs.) |
|------------|----------------------------------|------|----------|----------|
| 2079/Chaitra/15 | Debtors A/c (Gurung Store)      |      | 2,000    |          |
|            |   To Discount Allowed A/c        |      |          | 2,000    |
|            |   (Discount allowed for early payment) |      |          |          |

5. Control Accounts for Sales and Purchases

Control accounts summarize all individual customer/supplier balances in a single account. This avoids posting to every ledger individually.

A. Sales Ledger Control Account

Records all credit sales, returns, and cash receipts from debtors. Example for a Kathmandu Retail Shop (NPR):

| Particulars                          | Dr (Rs.) | Cr (Rs.) |
|--------------------------------------|----------|----------|
| **Opening Balance (Debtors)**        |          | 50,000   |
| **Sales to Gurung Store**            | 300,000  |          |
| **Sales Returns**                    |          | 15,000   |
| **Cash Received from Debtors**      |          | 250,000  |
| **Closing Balance**                   | 95,000   |          |
| **Total**                            | **395,000** | **315,000** |

B. Purchase Ledger Control Account

Records all credit purchases, returns, and cash payments to creditors. Example:

| Particulars                          | Dr (Rs.) | Cr (Rs.) |
|--------------------------------------|----------|----------|
| **Opening Balance (Creditors)**      | 40,000   |          |
| **Purchases from Nepal Wholesalers** |          | 80,000   |
| **Purchase Returns**                 | 5,000    |          |
| **Cash Paid to Creditors**           |          | 60,000   |
| **Closing Balance**                   | 25,000   |          |
| **Total**                            | **65,000** | **140,000** |

6. Bank Reconciliation for Sales/Purchase Transactions

Discrepancies arise due to:

• Unpresented cheques (cheques issued but not yet cleared by the bank).
• Bank charges (e.g., Ncell deducting transaction fees).
• Direct deposits (e.g., a customer paying via Khalti, which the bank records but the business’s cash book misses).

Example Reconciliation Statement (NPR): Assume:

• Cash Book Balance (Dr): Rs. 200,000
• Bank Statement Balance (Cr): Rs. 180,000
• Unpresented Cheques: Rs. 10,000
• Direct Deposit (Khalti): Rs. 5,000

**Bank Reconciliation Statement**
**As on: 2079/Chaitra/31**

| Particulars                          | Amount (Rs.) |
|--------------------------------------|--------------|
| **Cash Book Balance**                | 200,000      |
| **Less: Unpresented Cheques**       | (10,000)     |
| **Add: Direct Deposit (Khalti)**    | 5,000        |
| **Bank Statement Balance**           | **195,000**  |

Note: The bank statement shows Rs. 180,000, but after adjustments, the correct balance is Rs. 195,000.

## In the Real World

1. Daraz (Nepal’s Amazon)

   • Idea Used: Credit Sales and Discounts
   • How: Daraz offers "cash on delivery" (credit sales) and discounts for bulk orders (e.g., "Buy 2, Get 10% Off"). The platform records these in its Sales Ledger Control Account to track outstanding payments and apply discounts automatically.

2. Ncell (Telecom Provider)

   • Idea Used: Purchase Returns and Bank Reconciliation
   • How: When a customer returns a defective phone, Ncell processes a purchase return entry to adjust inventory and refund the customer. The bank reconciliation ensures that refunds via Khalti/eSewa match the company’s records.

3. Local Grocery Stores (e.g., BigMart, Reliance)

   • Idea Used: Cash vs. Credit Transactions
   • How: Stores like BigMart use cash sales for walk-in customers and credit sales for wholesale buyers (e.g., small shops). The Sales Day Book tracks credit sales, while the Cash Book records immediate payments.

4. Khalti/eSewa (Digital Payments)

   • Idea Used: Bank Reconciliation for Direct Deposits
   • How: When a customer pays via Khalti, the amount is directly deposited into the business’s bank account. The business must reconcile this with its Cash Book to avoid discrepancies (e.g., unrecorded transactions).

## Exam Tip

1. Always match the question type:

   • For journal entries, use the correct accounts (e.g., "Debtors A/c" for credit sales, not "Cash A/c").
   • For ledger postings, show debit and credit sides clearly with balances.

2. Discounts are tricky:

   • Trade discount = not recorded (only net amount is used).
   • Cash discount = recorded in a separate account (Discount Allowed/Received).

3. Control accounts save time:

   • In exams, if asked to prepare a Sales Ledger Control Account, list:
     • Opening balance
     • Total sales
     • Sales returns
     • Cash received
     • Closing balance.

4. Bank reconciliation is common:

   • Always adjust for:
     • Unpresented cheques (subtract from cash book balance).
     • Direct deposits (add to cash book balance).
     • Bank charges (subtract from bank statement balance).

5. Real-world examples score extra marks:

   • Relate answers to Nepali businesses (e.g., "Like Daraz’s bulk discounts" or "Similar to a local shop’s credit sales").

6. Trace the full cycle:

   • Start with journal entries, then ledger postings, and finally control accounts. Examiners check if you link all steps.
