Trial Balance & Financial Statements: Preparation, Errors & Analysis
Unit 4 of Financial Accounting covers the trial balance process, error detection, and preparation of income statements, balance sheets, and cash flow statements with Nepali business examples, t-accounts, and comparative analysis.
Core Concepts
1. Trial Balance: Definition and Purpose
The trial balance is a summary of all ledger accounts (debits and credits) at a specific date to check if debits equal credits. It is not a financial statement but a preliminary tool to detect errors before preparing final accounts.
Why is it prepared?
- Ensures arithmetical accuracy (debits = credits).
- Helps identify accounting errors (omissions, mispostings, etc.).
- Serves as a starting point for financial statements.
Types of Errors Detected by Trial Balance
| Detected by Trial Balance | Not Detected by Trial Balance |
|---|---|
| 1. Complete omission (e.g., a transaction not recorded at all) | 1. Compensating errors (two errors cancel each other out) |
| 2. One-sided errors (e.g., only debit or only credit recorded) | 2. Errors of principle (e.g., treating revenue as capital) |
| 3. Wrong amount errors (e.g., Rs. 500 recorded as Rs. 50) | 3. Errors of commission (e.g., wrong account debited/credited) |
| 4. Transposition errors (e.g., Rs. 123 written as Rs. 132) | 4. Errors of omission (e.g., a transaction partially recorded) |
2. Adjusting Entries and Adjusted Trial Balance
Before preparing financial statements, adjusting entries are made to:
- Accrue revenues/expenses (e.g., unearned rent, accrued salaries).
- Record depreciation (e.g., on machinery).
- Adjust inventories (e.g., closing stock valuation).
- Correct errors (e.g., bad debts provision).
Example: Adjusting Entries for a Kathmandu Retail Shop (NPR)
Assume Kathmandu Mart has the following unadjusted trial balance as of 31 Chaitra 2078:
| Particulars | Debit (Rs.) | Credit (Rs.) |
|---|---|---|
| Cash | 200,000 | |
| Accounts Receivable | 150,000 | |
| Inventory (Opening) | 80,000 | |
| Purchases | 500,000 | |
| Salaries Expense | 100,000 | |
| Rent Expense | 60,000 | |
| Sales Revenue | 800,000 | |
| Capital | 500,000 | |
| Total | 1,090,000 | 1,300,000 |
Adjustments:
- Closing Inventory (Rs. 120,000) – Not yet recorded.
- Accrued Salaries (Rs. 20,000) – Unpaid as of 31 Chaitra.
- Depreciation on Equipment (Rs. 10,000) – Straight-line method (5% on Rs. 200,000).

Financial Statements Preparation
1. Income Statement (Profit & Loss Account)
Shows revenue, expenses, and net profit/loss for a period.
Format (Single-Step):
| Particulars | Amount (Rs.) |
|---|---|
| Revenue: | |
| Sales Revenue | 800,000 |
| Less: Expenses | |
| Cost of Goods Sold | (600,000) |
| Salaries Expense | (120,000) |
| Rent Expense | (60,000) |
| Depreciation Expense | (10,000) |
| Total Expenses | (790,000) |
| Net Profit | 10,000 |
2. Balance Sheet (Statement of Financial Position)
Shows assets, liabilities, and equity at a point in time.
Format (Vertical):
| Assets | Liabilities & Equity |
|---|---|
| Current Assets: | Current Liabilities: |
| Cash | 200,000 |
| Accounts Receivable | 150,000 |
| Inventory | 120,000 |
| Total Current Assets | 470,000 |
| Non-Current Assets: | |
| Equipment (Net) | 190,000* |
| Total Assets | 660,000 |
*Equipment (Rs. 200,000 - Rs. 10,000 depreciation)
3. Cash Flow Statement
Classifies cash flows into three activities:
- Operating Activities (core business)
- Investing Activities (assets purchase/sale)
- Financing Activities (loans, dividends, equity)
Example: Kathmandu Mart’s Cash Flow (Simplified)
| Activity | Cash Inflow (Rs.) | Cash Outflow (Rs.) | Net Cash Flow (Rs.) |
|---|---|---|---|
| Operating: | |||
| Sales Revenue | 800,000 | +800,000 | |
| Less: Purchases | 500,000 | ||
| Less: Salaries | 100,000 | ||
| Less: Rent | 60,000 | ||
| Net Operating Cash Flow | +140,000 | ||
| Investing: | |||
| Purchase of Equipment | 200,000 | -200,000 | |
| Financing: | |||
| Capital Injection | 500,000 | +500,000 | |
| Net Change in Cash | +440,000 |
In the Real World
eSewa (Nepal)
- Trial Balance & Adjustments: eSewa’s accounting system uses automated trial balances to reconcile transactions (e.g., mobile top-ups, bill payments) before generating financial reports for tax compliance.
- Income Statement: Tracks revenue from commissions (e.g., 5% on bill payments) vs. operating expenses (servers, salaries) to report net profit.
Ncell (Nepal)
- Cash Flow Statement: Ncell classifies cash flows into:
- Operating: Revenue from SIM sales, call charges.
- Investing: Purchase of new telecom towers.
- Financing: Loan repayments, dividend payouts.
- Error Detection: Uses trial balances to catch discrepancies in prepaid vs. postpaid billing errors.
- Cash Flow Statement: Ncell classifies cash flows into:
Daraz (Nepal/Alibaba Group)
- Inventory Adjustments: Daraz adjusts closing stock (e.g., unsold electronics) in its trial balance before preparing the income statement to calculate Cost of Goods Sold (COGS) accurately.
- Depreciation: Records depreciation on warehouse equipment (e.g., forklifts) in adjusting entries.
Worked Example: NTC’s Revenue Recognition
Scenario: Nepal Telecommunications Corporation (NTC) provides Rs. 50,000/month for a 12-month broadband plan but recognizes revenue monthly (accrual basis).
| Month | Cash Received (Rs.) | Revenue Recognized (Rs.) | Unearned Revenue (Rs.) |
|---|---|---|---|
| Jan | 50,000 | 50,000 | 0 |
| Feb | 0 | 50,000 | 50,000 |
| Mar | 0 | 50,000 | 100,000 |
| ... | ... | ... | ... |
| Dec | 0 | 50,000 | 0 |
Adjusting Entry (Feb):
Why? Ensures revenue is matched with expenses (e.g., bandwidth usage) under the accrual concept.
Exam Tip
Trial Balance Errors:
- Always check if debits = credits. If not, look for omissions or one-sided entries.
- Compensating errors (e.g., Rs. 100 overstated in one account, Rs. 100 understated in another) won’t affect the trial balance but will distort financial statements.
Adjusting Entries:
- Memorize the 4 types:
- Accruals (unrecorded revenues/expenses).
- Deferrals (prepaid/unearned items).
- Estimates (depreciation, bad debts).
- Corrections (error fixes).
- Example: If rent paid in advance (Rs. 30,000) is recorded as an expense, adjust:
flowchart TD A["Prepaid Rent (Dr. 30,000)"] -->|"Reverse entry"| B["Rent Expense (Cr. 30,000)"]
- Memorize the 4 types:
Financial Statements:
- Income Statement: Revenue - Expenses = Net Profit.
- Balance Sheet: Assets = Liabilities + Equity.
- Cash Flow Statement: Operating + Investing + Financing = Net Change in Cash.
Common Exam Traps:
- Ignoring adjustments → Leads to incorrect net profit.
- Miscounting totals → Always double-check debits vs. credits.
- Mixing accrual with cash basis → Remember: Revenue is recognized when earned, not when cash is received.
Final Checklist for Exams
✅ Trial Balance: Debits = Credits? If not, find the error. ✅ Adjustments: Did you record depreciation, accruals, and inventory? ✅ Income Statement: Did you match revenues with expenses? ✅ Balance Sheet: Do assets = liabilities + equity? ✅ Cash Flow: Did you classify transactions correctly (operating, investing, financing)?
