1. The Purpose of Accounting and Key Principles | 会计的目的与基本原则
Accounting is the process of recording, classifying, and summarising financial transactions to provide useful information for decision-making by owners, managers, and other stakeholders.
会计是记录、分类和汇总财务交易的过程，旨在为业主、管理者及其他利益相关方提供有用信息以辅助决策。
The fundamental accounting concepts include business entity, money measurement, going concern, accruals, consistency, and prudence. These ensure that financial statements are reliable and comparable.
基本会计概念包括会计主体、货币计量、持续经营、应计制、一致性和审慎性。这些概念确保财务报表可靠且可比。
Assets = Liabilities + Capital, underpins the double-entry system and must always balance.
会计等式“资产 = 负债 + 资本”是复式记账体系的基石，必须始终保持平衡。
2. Double-Entry Bookkeeping and Ledger Accounts | 复式记账与分类账
Every business transaction is recorded in ledger accounts using the double-entry system, where one account is debited and another is credited with an equal amount.
每笔企业交易都运用复式记账法记录于分类账户，一个账户记入借方，另一个账户记入贷方，金额相等。
A 'T-account' visually separates debits (left) and credits (right). For assets and expenses, increases are debited; for liabilities, capital, and income, increases are credited.
“T 形账户”将借方（左）和贷方（右）分开。资产与费用增加计借方；负债、资本与收益增加计贷方。
The books of prime entry (e.g., sales day book, purchases day book, cash book) record transactions initially before posting to the ledger.
原始分录簿（如销售日记账、采购日记账、现金簿）先记录交易，随后过账至分类账。
3. Trial Balance and the Correction of Errors | 试算平衡表与错误更正
A trial balance is a list of all ledger balances at a specific date, checking that total debits equal total credits. It helps detect mathematical errors but does not prove complete accuracy.
试算平衡表是特定日期所有分类账余额的列表，用于检查借方总额是否等于贷方总额。它有助于发现数学错误，但不能证明完全准确。
Errors not revealed by the trial balance include omission, commission, principle, complete reversal, original entry, and compensating errors.
试算平衡表无法揭示的错误包括遗漏、过账错误、原则性错误、完全颠倒、原始分录错误及抵消错误。
Where debits ≠ credits, a suspense account is temporarily used to make the trial balance agree while the error is located and corrected via journal entries.
若借方总额不等于贷方总额，可暂时使用暂记账户使试算表平衡，同时查找错误并通过日记账分录进行更正。
4. Financial Statements: Income Statement | 财务报表：利润表
The income statement (profit and loss account) calculates the profit or loss of a sole trader over an accounting period. It starts with revenue and deducts cost of sales to find gross profit.
利润表（损益表）计算独资经营者某一会计期间的利润或亏损。它从收入开始，减去销售成本得出毛利。
riage inwards − Closing inventory. Gross profit = Revenue − Sales returns − Cost of sales.
销售成本 = 期初存货 + 购货 − 购货退回 + 购货运费 − 期末存货。毛利 = 销售收入 − 销售退回 − 销售成本。
Then, other operating expenses (rent, wages, depreciation, etc.) are subtracted from gross profit to arrive at net profit. Be careful to adjust for accruals and prepayments.
然后，从毛利中扣除其他营业费用（租金、工资、折旧等）得出净利润。务必对应计和预付进行调整。
5. Financial Statements: Statement of Financial Position | 财务报表：资产负债表
The statement of financial position shows the assets, liabilities, and capital of the business at a point in time. It follows the accounting equation.
资产负债表反映企业在某一时点的资产、负债和资本状况，遵循会计等式。
Non-current assets (e.g., machinery, vehicles) are listed at net book value (cost less accumulated depreciation). Current assets include inventory, trade receivables, and cash.
非流动资产（如机器设备、车辆）按账面净值（成本减累计折旧）列示。流动资产包括存货、应收贸易账款和现金。
Current liabilities (payables, bank overdraft) are deducted from current assets to show net current assets. The capital section includes opening capital plus net profit less drawings.
流动负债（应付账款、银行透支）从流动资产中扣除，得到净流动资产。资本部分包括期初资本加净利润减提款。
6. Depreciation of Non-Current Assets | 非流动资产的折旧
Depreciation allocates the cost of a non-current asset over its useful life, matching the expense to the revenue generated. Two common methods: straight-line and reducing balance.
折旧将非流动资产成本在其使用年限内分摊，使费用与产生的收入配比。两种常用方法：直线法和余额递减法。
The straight-line formula:
Annual Depreciation = (Cost − Residual Value) ÷ Useful Life
直线法公式：年折旧额 = (成本 − 残值) ÷ 使用年限
Reducing balance method applies a fixed percentage to the net book value each year, resulting in higher depreciation early in the asset’s life.
余额递减法每年对账面净值乘以一个固定百分比，导致资产使用前期折旧费用较高。
In the ledger, the depreciation expense is debited to the income statement and credited to the accumulated depreciation account, which reduces the asset’s carrying amount.
在分类账中，折旧费用借记利润表，贷记累计折旧账户，从而降低资产账面价值。
7. Bad Debts and Provision for Doubtful Debts | 坏账与呆账准备
A bad debt arises when a trade receivable is deemed uncollectable and is written off as an expense. The double entry is: debit bad debts account, credit trade receivables account.
当应收贸易账款被认定无法收回时，便产生坏账，需作为费用冲销。会计分录为：借记坏账账户，贷记应收贸易账款账户。
A provision for doubtful debts estimates the likely uncollectable amount, applying the prudence concept. The adjustment increases expenses and creates a provision (a contra-asset) on the statement of financial position.
呆账准备是对可能无法收回金额的估计，遵循审慎性原则。该调整增加费用，并在资产负债表中设立准备（资产备抵项目）。
An increase in provision is an additional expense; a decrease is recorded as other income. The net trade receivables figure is shown after deducting both specific bad debts and the provision.
准备增加额是追加费用；减少额则记为其他收益。应收贸易账款净额需扣除特定坏账及准备后列示。
8. Accruals and Prepayments | 应计与预付
Under the accruals concept, expenses and income are recorded when they are incurred or earned, not when cash changes hands. Adjustments for accruals and prepayments are vital for accurate profit measurement.
根据应计制概念，费用和收入应在发生或赚取时记录，而非现金收付时。应计与预付的调整对准确衡量利润至关重要。
An accrued expense is an amount owed but not yet paid; it is added to the relevant expense in the income statement and shown as a current liability.
应计费用指已发生但尚未支付的款项；在利润表中加计至相关费用，并作为流动负债列示于资产负债表。
A prepayment is an amount paid in advance for the next period; it is deducted from the expense in the income statement and appears as a current asset.
预付费用指为下期预先支付的款项；在利润表中从费用中扣除，并作为流动资产列示。
9. Control Accounts | 控制账户
Control accounts are summary accounts in the general ledger that reflect the total of individual balances in the sales ledger (trade receivables) and purchases ledger (trade payables).
控制账户是总分类账中的汇总账户，反映销售明细账（应收贸易账款）和采购明细账（应付贸易账款）中各账户的余额总额。
The sales ledger control account is debited with total credit sales and credited with receipts, discounts allowed, and bad debts. Its balance should equal the sum of individual debtor balances.
销售明细账控制账户借方记赊销总额，贷方记收款、销货折扣和坏账。其余额应等于各债务人账户余额总和。
Control accounts help locate errors, prevent fraud, and provide a quick check on total receivables and payables without examining individual accounts.
控制账户有助于查找错误、防止舞弊，并能在不逐一检查各账户的情况下快速核对应收和应付款项总额。
10. Bank Reconciliation | 银行对账
A bank reconciliation statement explains the difference between the cash book balance and the bank statement balance, due to timing differences and errors.
银行余额调节表用于解释由时间性差异和错误导致的现金簿余额与银行对账单余额之间的差异。
Common reconciling items: unpresented cheques (deduct from bank statement balance), deposits in transit (add to bank statement balance), bank charges and interest (adjust cash book).
常见调节项目：未兑现支票（从银行对账单余额中扣除）、在途存款（加至银行对账单余额）、银行手续费和利息（调整现金簿）。
After adjusting the cash book for errors and direct debits/credits, the adjusted cash book balance equals the adjusted bank balance, confirming accuracy.
对现金簿的错误和直接借记/贷记进行调整后，调整后的现金簿余额应等于调整后的银行余额，从而确认准确性。
11. Ratio Analysis and Interpretation | 比率分析与解读
Ratio analysis evaluates the financial performance and position of a business. Profitability ratios include gross profit margin and net profit margin.
比率分析用于评估企业的财务业绩和状况。盈利能力比率包括毛利率和净利润率。
Gross Profit Margin = (Gross Profit ÷ Revenue) × 100
Net Profit Margin = (Net Profit ÷ Revenue) × 100
Liquidity ratios assess the ability to meet short-term obligations: current ratio and acid test (quick) ratio.
流动性比率评估企业清偿短期债务的能力：流动比率和酸性测试（速动）比率。
Current Ratio = Current Assets ÷ Current Liabilities
Acid Test Ratio = (Current Assets − Closing Inventory) ÷ Current Liabilities
Other important measures: trade receivables collection period and trade payables payment period, which help evaluate working capital management.
其他重要指标：应收贸易账款回收期和应付贸易账款支付期，有助于评价营运资金管理。
Trade Receivables Collection Period = (Trade Receivables × 365) ÷ Credit Sales
Interpreting trends and comparing to industry benchmarks provides valuable insights into business efficiency and stability.
分析趋势并与行业基准进行比较，能为企业效率和稳定性提供宝贵洞见。
