Accounting is the process of identifying, measuring, recording, and communicating financial information about an entity to interested parties. It emphasizes accuracy, transparency, and relevance to support management and control of resources.

Branches
Financial Accounting
Recording business transactions to determine the operating result of a period and the financial position on a given date. Mandatory and audited externally.
Income statement and balance sheet are prepared using historical transactions. To show the operating result of a fixed period and the financial position on a given date. The period is usually a financial year (aka. fiscal year).
Used by stakeholders, creditors, tax authorities, regulators.
Governed by financial reporting standards such as IFRS or GAAP, which fix the format, terminology, and recognition rules for each statement. As every company follows the same rules, an external user can compare 2 companies’ statements directly, without needing to know each company’s internal accounting choices.
Cost Accounting
Collection, classification, and ascertainment of the cost of production, including tracking and controlling project costs, materials, and labor.
Cost sheets and cost reports are prepared per product, job, or process. To track and control the cost of production. Tracked continuously as production happens, not tied to a fixed period.
Used by production and operations managers.
Basis is both historical cost and predetermined standard cost, the latter used to spot variances against actual cost. Feeds cost data into management accounting for pricing and efficiency decisions.
Management Accounting
Uses financial and cost accounting data for policy formulation, planning, control, and decision-making by management.
Budgets, forecasts, and performance reports are prepared using financial and cost accounting data. To support planning, control, and decision-making. Forward-looking, with no fixed reporting cycle.
Used by management, at all levels of the organization.
Basis combines historical data with projections and estimates. Not governed by external reporting standards, so report format is chosen freely to fit the decision at hand.
Financial Accounting vs Management Accounting
- Objective
Financial accounting is stewardship for the benefit of shareholders. Management accounting improves the economy, efficiency, and effectiveness of operations. - Time horizon
Financial accounting looks only at the past. Management accounting looks at the past, present, and future. - Outputs
Financial accounting produces a summary annual statement of profit or loss and other comprehensive income, statement of financial position, and statement of cash flow. Management accounting produces detailed monthly and annual accounts by product and function, plus adhoc reports.
Concepts
Business Entity Concept
The business is a distinct accounting entity, separate from its owners.
Examples:
- The owner’s personal car purchase is not recorded in the business’s books.
Money Measurement Concept
Only information expressible in monetary terms is recorded.
Examples:
- Employee skill and brand reputation are not recorded, since neither can be reliably expressed in money.
Historical Cost Concept
Assets are shown at cost, not current market value.
Examples:
- Land bought 10 years ago for $50,000 is still recorded at $50,000, even if its current market value is $200,000.
Periodic Concept
Income or loss is measured over a fixed accounting period, e.g. calendar year (1 Jan to 31 Dec) or financial year (1 April to 31 March).
A business actually runs continuously, with no natural stopping point. The periodic concept cuts that continuous life into artificial fixed-length slices so results can be reported and compared at regular intervals, instead of only once, when the business eventually winds up.
Examples:
- A company closes its books every 31 March and reports that year’s profit, regardless of projects still in progress.
Matching Concept
Expenses incurred in a period are matched with the revenue earned in that period.
An expense is recorded in the same period as the revenue it helped generate, not in whichever period the cash happens to move. This keeps a period’s profit figure meaningful: it reflects the cost of earning that period’s revenue, not just that period’s cash outflows.
Examples:
- Commission owed for a sale made in March is recorded as a March expense, even if paid out in April.
Materiality Concept
Information is material iff its misstatement could influence the economic decisions of users.
Materiality is a threshold, not a fixed amount. It depends on the size of the item relative to the business, so the same dollar figure can be material for a small company and immaterial for a large one. Below the threshold, strict accounting treatment is skipped in favor of the simplest treatment, since the extra precision would not change any user’s decision.
Examples:
- A $2 stationery purchase is expensed immediately instead of depreciated, since tracking it changes no decision.
Going Concern Concept
The business is assumed to continue operating for the foreseeable future.
Examples:
- Machinery is valued as a productive asset in use, not at its forced-sale liquidation price.
Consistency Concept
Accounting methods are applied uniformly across periods.
Examples:
- A company using straight-line depreciation continues with it every year, instead of switching methods to alter reported profit.
Accrual Concept
Accounts are prepared on an accrual basis by default, though some entities use cash basis.
Examples:
- A sale made in December is recorded as December revenue, even if cash is received in January.
Realization Concept
Revenue is realized when goods or services are actually delivered.
Prudence Concept
Assets or profits are not overstated, and losses are not understated.
Examples:
- Recognize provision for trade receivable impairment.
- Recognize stock losses.
- Recognize gratuity provision expenses.
