Unit-II: Recording Transactions and Trial Balance
1. Nature of Business Transactions & Journal Entries
A business transaction is any economic event involving an exchange of value that directly alters the financial position of an enterprise and can be reliably measured in monetary terms.
DOUBLE-ENTRY RECORDING PROCESS
|
[ Economic Event ] —> [ Source Document ] —> [ Analysis (Debit/Credit) ] —> [ Journal Entry ]
Modern Approach (Equation-Based Rules)
| Account Classification | Debit Increase (+) | Credit Increase (+) |
|---|---|---|
| Assets | Debit to Increase | Credit to Decrease |
| Expenses / Losses | Debit to Increase | Credit to Decrease |
| Liabilities | Credit to Decrease | Debit to Increase |
| Capital / Equity | Credit to Decrease | Debit to Increase |
| Revenue / Gains | Credit to Decrease | Debit to Increase |
2. Purchases, Sales, Returns, Receivables, and Payables
Trading operations require systematic accounting for merchandise inventory, cash/credit sales, purchases, and customer or vendor adjustments.

3. Inventory Accounting
Inventory comprises held-for-sale goods, items in production (work-in-progress), and raw materials consumed during manufacturing.
INVENTORY SYSTEM MODELS
|
+————————————-+————————————-+
| |
PERIODIC INVENTORY SYSTEM PERPETUAL INVENTORY SYSTEM
Cost of Goods Sold (COGS) calculated at period-end Continuous real-time tracking of inventory balance
COGS = Opening + Purchases − Ending Stock account adjusted after every transaction
Inventory Valuation Methods
- FIFO (First-In, First-Out): Assumes the earliest acquired inventory units are sold first. Ending inventory reflects current market costs.
- LIFO (Last-In, First-Out): Assumes the latest acquired inventory units are sold first. Matches current revenue with current costs.
- Weighted Average Cost: Valuations are based on the weighted average cost of all units available during the period:
Weighted Average Cost per Unit = Total Cost of Goods Available for Sale ÷ Total Units Available for Sale
4. Depreciation, Amortizations, and Reserves
Non-current assets gradually lose utility over time. Accounting records this systematic expense to reflect accurate asset values and earnings.
ASSET DEPRECIATION & RESERVES

+——————-+—————–+—————–+——————-+
| | | | |
DEPRECIATION AMORTIZATION IMPAIRMENT PROVISIONS RESERVES
(Tangible asset (Intangible asset (Unexpected drop (Known liabilities (Retained earnings
wear & tear) value reduction) in asset value) unsettled in value) allocated for growth)
Standard Depreciation Methods
Straight-Line Method (SLM):
Annual Depreciation = (Original Cost − Estimated Residual Value) ÷ Estimated Useful Life (Years)
Written Down Value Method (WDV) / Reducing Balance: Depreciation is calculated as a fixed percentage applied annually to the declining book value of the asset.
Depreciation Charge (Year t) = Book Valuet−1 × Depreciation Rate (r)
5. Intangible Assets Accounting
An intangible asset is an identifiable non-monetary asset without physical substance (e.g., patents, copyrights, trademarks, goodwill, computer software).
| Intangible Asset Type | Recognition Criterion | Accounting Treatment |
|---|---|---|
| Purchased Goodwill | Acquired via business takeover | Capitalized on Balance Sheet; tested annually for impairment |
| Patents & Trademarks | Direct acquisition / legal costs | Capitalized and amortized over legal or useful life |
| Internal R&D Costs | Research phase vs. Development phase | Research: Expensed immediately Development: Capitalized if criteria are met |
6. Goods and Services Tax (GST) Transactions
GST is a destination-based indirect tax levied on the supply of goods and services.
GST TAX STRUCTURE
|
+————————————+————————————+
| |
INTRA-STATE SUPPLY (Within State) INTER-STATE SUPPLY (Between States)
Split equally into two components: Single unified indirect tax:
• CGST (Central Goods & Services Tax) • IGST (Integrated Goods & Services Tax)
• SGST (State Goods & Services Tax)
| Transaction Type | Tax Account Used | Journal Entry Impact |
|---|---|---|
| Purchase of Goods | Input Tax Credit (ITC) | Debit: Input CGST / Input SGST / Input IGST |
| Sale of Goods | Tax Output Liability | Credit: Output CGST / Output SGST / Output IGST |
Net Tax Payable = Total Output GST Liability − Eligible Input Tax Credit (ITC)
7. Entry in Ledger
The Ledger is the principal book of accounts where journalized entries are classified and summarized into individual T-Accounts.
| Dr. | [ ACCOUNT NAME ] | Cr. | ||||
|---|---|---|---|---|---|---|
| Date | Particulars | Amount | Date | Particulars | Amount | |
| YYYY-MM-DD | To Counter Account | X,XXX | YYYY-MM-DD | By Counter Account | X,XXX | |
8. Trial Balance & Correction of Errors
A Trial Balance is a summary statement of debits and credits extracted from all ledger accounts on a given date to check arithmetical accuracy.
CLASSIFICATION OF ACCOUNTING ERRORS
|
+—————————————+—————————————+
| |
ERRORS DISCLOSED BY TRIAL BALANCE ERRORS NOT DISCLOSED BY TRIAL BALANCE
(Arithmetical discrepancies & single-sided errors) (Debits equal credits, but accounting is wrong)
• Cast errors / Column summation mistakes • Error of Omission: Entire transaction missing
• Posting incorrect amount to one side • Error of Commission: Posted to wrong person/account
• Omission of ledger balance in Trial Balance • Error of Principle: Capital treated as Revenue
• Compensating Errors: Offsetting mistakes
| Error Category | Underlying Mistake | Correction Strategy |
|---|---|---|
| Error of Principle | Violates capital vs. revenue rules (e.g., Repairs debited to Building) | Pass rectifying entry transferring item to correct account (e.g., Debit Repairs A/c, Credit Building A/c) |
| One-Sided Error | Disruption in single account balancing | Correct via Suspense Account if discovered post-trial balance |
Key Learning Summary
| Section | Primary Operational Takeaway |
|---|---|
| Journal & Ledger | Record transactions in chronological order before posting them to individual ledger accounts. |
| Inventory Models | FIFO reflects current replacement costs; Periodic/Perpetual methods determine COGS structure. |
| Depreciation & Amortization | Systematically allocate asset cost over its useful economic life. |
| GST Accounting | Input Tax Credit (ITC) offsets Output GST liability. |
| Trial Balance & Errors | Arithmetical equality does not guarantee freedom from principles or complete omissions. |
