Accounting concepts explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Accounting concepts are the working rules that decide what goes into the books, when it goes in and at what amount. Some are stated in an Accounting Standard, some in the Framework behind the standards, and some are simply the habits that make a set of books understandable. This guide takes each one, gives an example, and shows where it appears in the accounts, which is also how our bookkeeping and online accounting team checks a client's books.
Three concepts are fundamental assumptions under AS 1, paragraph 10: going concern, consistency and accrual. Three more govern the choice of policies under paragraph 17: prudence, substance over form and materiality. The remaining ones, business entity, money measurement and matching, are the working conventions that every bookkeeper uses. Where a fundamental assumption is not followed, the fact must be disclosed (paragraph 9).
Where the concepts come from
AS 1 groups going concern, consistency and accrual as fundamental assumptions that are usually not stated because their acceptance is assumed (paragraphs 9 and 10). It separately lists prudence, substance over form and materiality as the major considerations for selecting accounting policies (paragraph 17). The Framework repeats accrual, going concern and consistency at paragraphs 22 to 24, and covers substance and prudence at paragraphs 35 and 37. Our guide to AS 1 on accounting policies covers the standard in full; this article is about the ideas.
The concepts in a table
| Concept | What it means | Example | Where it shows in the accounts |
|---|---|---|---|
| Business entity | The business is separate from its owner | A proprietor's household electricity bill is drawings, not a shop expense | Drawings account; owner's capital |
| Money measurement | Only items that can be stated in money are recorded | A skilled manager is not an asset; a loan to the shop is | Absence of "people" from the balance sheet |
| Going concern | The business will continue (AS 1, para 10) | A van is carried at cost less depreciation, not at what a forced sale would fetch | Depreciation, fixed assets at cost |
| Accrual | Record when earned or incurred, not when cash moves (AS 1, para 10) | March sales on credit are March income | Debtors, creditors, outstanding and prepaid items |
| Consistency | Same policies from year to year | Stock is valued on the same formula each year | Policy note; comparable figures |
| Matching | Set costs against the income they helped earn | Cost of the goods sold in the year is charged against that year's sales | Cost of goods sold, closing stock |
| Prudence | Do not anticipate profit; provide for known losses | A doubtful debtor is provided for | Provision for doubtful debts |
| Substance over form | Record the economic reality, not the legal wrapper | Goods held for a customer and already paid for are treated according to the reality of the deal | Revenue and asset recognition |
| Materiality | Disclose items that would influence a user's decision | A single pen is not tracked as an asset | Level of detail in notes |
The wording that matters
Three paragraphs are worth reading in the original. Paragraph 10 describes going concern as continuing in operation for the foreseeable future, with neither the intention nor the necessity of liquidation. Paragraph 17 says that under prudence "profits are not anticipated but recognised only when realised though not necessarily in cash". The same paragraph asks that provision be made for all known liabilities and losses even where the amount cannot be fixed with certainty.
On materiality, paragraph 17 asks for disclosure of items "the knowledge of which might influence the decisions of the user". There is no fixed percentage in the standard, so a figure that is trivial for a large company can be material for a small shop.
Worked example: one year of a stationery shop
The entity and all figures in this example are invented for illustration.
Anita Stationers keeps books for the year ended 31 March 2026. The facts:
- Credit sales for the year are 7,50,000; customers have paid 6,50,000 so far.
- Goods that were sold cost 4,20,000, all paid in cash.
- Rent paid in the year is 90,000, of which 15,000 is for April 2026.
- Electricity paid is 40,000; the March bill of 8,000 arrives in April.
- One debtor owing 10,000 is doubtful.
Cash view (money in less money out).
| Particulars | Amount |
|---|---|
| Cash from customers | 6,50,000 |
| Less: goods 4,20,000 + rent 90,000 + electricity 40,000 | 5,50,000 |
| Cash surplus | 1,00,000 |
Accrual and matching view.
| Particulars | Amount |
|---|---|
| Sales (accrual) | 7,50,000 |
| Less: cost of goods sold | 4,20,000 |
| Gross profit | 3,30,000 |
| Less: rent (90,000 less 15,000 prepaid) | 75,000 |
| Less: electricity (40,000 + 8,000 accrued) | 48,000 |
| Profit before provision | 2,07,000 |
| Less: provision for doubtful debt (prudence) | 10,000 |
| Profit for the year | 1,97,000 |
Reconciling the two views. Cash surplus 1,00,000 plus debtors 1,00,000 (7,50,000 less 6,50,000) plus prepaid rent 15,000 less electricity accrued 8,000 gives 2,07,000. Deducting the 10,000 provision leaves 1,97,000.
Check: 1,00,000 + 1,00,000 + 15,000 - 8,000 = 2,07,000; 2,07,000 - 10,000 = 1,97,000, equal to the profit in the accrual statement. The same-policy test (consistency) is met provided the shop provided for doubtful debts in the same way last year; if not, the change must be disclosed.
Cash accounting has its place; see our note on cash and accrual accounting. The Framework's paragraph 22, however, says financial statements are prepared on the accrual basis.
Conventions in daily book-keeping
Business entity. Never mix the owner's spending with the business account. In a partnership, each partner's drawings go to a drawings or current account.
Money measurement. Staff skills or goodwill built up over the years do not appear in the books because they have no transaction price; a loan taken from the bank does.
Consistency. The Framework (paragraph 24) allows a change of policy only in exceptional circumstances, and the effect is disclosed, as our guide on AS 5 and changes in accounting policies explains.
Materiality. Small items are expensed in the year even if they last longer; for example, a 400 rupee stapler does not go into the fixed asset register.
Need help with books that follow the concepts?
If your accounts mix owner and business spending, skip accruals or have unsettled policies, we can set up the books and review the year-end entries. Our bookkeeping and online accounting team works with small businesses on exactly these points.
Key takeaways
- Going concern, consistency and accrual are the fundamental assumptions in AS 1.
- Prudence, substance over form and materiality guide the choice of policies.
- Cash profit and accrual profit differ by debtors, creditors, prepaid and accrued items.
- Prudence means no anticipated profits and provision for known losses.
- A change in policy must be disclosed.
