Notes on the fundamentals

I need to explain Chapter 1 of Class 11 Accounts to a student, and much of it is framed around a small business with one owner. That is a sensible way to teach it. But I work in a company's finance team, where the same ideas are carried out by people, systems and rules the chapter never mentions, and a student who only gets the shop version will find a different picture in their first job. So I went through the chapter section by section and asked the same thing of each: what does this look like inside a company, and does it still hold? I set the finance process cycles I usually think in aside and stayed with accounting itself.

1.1

Meaning of Accounting

Start with a grocery shop. In a month the owner buys goods worth ₹5,00,000, sells them for ₹8,00,000 and pays ₹5,000 for electricity. If they only watch goods going in and coming out, the profit looks like ₹3,00,000. Once the electricity is counted it is ₹2,95,000, assuming everything bought was sold. Accounting is what makes sure the electricity bill, and everything like it, is not forgotten.

The textbook describes accounting as a process rather than just writing things down, and the process has seven steps. Here they are applied to one ordinary company transaction: buying ₹10,000 of raw material from a supplier.

StepWhat it meansThe raw material purchase
1. IdentificationDeciding whether an event is a financial transactionThe purchase changes what the company owns and owes, so it counts. (A new manager joining does not; that is an HR record, not an accounting one.)
2. MeasurementPutting a money value on it₹10,000 plus 18% GST of ₹1,800, so the supplier's invoice is ₹11,800
3. RecordingWriting it in the journalDebit inventory ₹10,000 and input GST ₹1,800; credit the supplier (accounts payable) ₹11,800
4. ClassificationGrouping similar entries together in the ledgerThe entry lands in the inventory, GST and accounts payable accounts
5. SummarisingCompiling the ledgers into statementsThe month-end trial balance, profit and loss account and balance sheet
6. Analysis and interpretationWorking out what the numbers meanIs inventory building up? Are suppliers being paid faster or slower than before?
7. CommunicationGetting it to the people who need itReports to management; statements to investors, banks and the government

The GST sits apart from the inventory because a registered company can generally claim it back as input tax credit, so it is not part of what the material cost.

Correction that mattered

What I had not expected was who does what. Asked which of these steps a person performs, my answer was steps one to four. I had it the wrong way round for routine transactions. When goods are received against a purchase order, an ERP system such as SAP works out the transaction from the order, takes the rate from it, creates the journal entry and posts it to the right accounts. I do not type it. That only works because of set-up done once, earlier: a rate on the purchase order, and an account already attached to the item. Without that, the system has nothing to post from.

It holds only for rule-driven entries, though. Where an entry rests on an estimate or a judgment, a person still has to decide. When the month closes and the electricity bill has not arrived, I estimate the amount and key in the accrual myself. A provision for a legal claim is the same: someone has to judge how much to set aside, and the system cannot do that for them.

Step five is also mostly the system's work, since the trial balance, profit and loss account and balance sheet come out of it at month-end. What a person adds is in steps six and seven: reading the numbers, checking they make sense, explaining what moved, and getting the picture to management.

That is also where the three words in the chapter finally separated for me. Bookkeeping is the first four steps: identifying, measuring, recording and classifying. Accounting is the whole seven-step process, which adds summarising, analysing and interpreting, and communicating. Accountancy is the discipline underneath both, the principles, rules and theory that say how all of it should be done.

Common mistake

I tried to define bookkeeping as "what the software does automatically" and accounting as "the entries that need judgment." It sounds right and it isn't, because the two ideas answer different questions. Bookkeeping and accounting are defined by stage, meaning which of the seven steps we are in. Automatic or manual is about how a step gets done. A judgment-based accrual is still bookkeeping, because it is a recording step. I even called the trial balance bookkeeping, but it belongs to the summarising step, which is past bookkeeping however automatically it is produced.

1.2

Accounting as a Source of Information

Accounting information has two kinds of users. Internal users are the owner and management, who need it to run the business day to day: what profit was made, where cash is stuck, whether inventory levels are right, how much is owed to each supplier. External users sit outside the company. A bank wants to know whether it can lend and be repaid, an investor wants to know whether their money is safe, and the government wants to calculate tax.

When I was asked whether one report serves both groups, I said they get two, and that held up. Management gets internal reports that are detailed and frequent, daily or weekly, and built for decisions: inventory status, cash flow, supplier performance, department-wise spending. Investors, banks and the government get the financial statements, meaning the profit and loss account, balance sheet and cash flow statement, in a standard format, prepared at least once a year, audited, and shaped by legal requirements. Both come out of the same system and the same underlying data; they are just built differently for different readers.

An example makes the difference concrete. Say the company writes off ₹50,000 of inventory. Management wants the detail: which item, why (damage, theft, expiry), and what it does to the quarter's forecast. The published statements carry only the summarised figure, without the item-level detail.

The way I first put it was that a management report and a financial report are two different things. That is right. Accounting is one process, but the information has to be cut differently for each audience.

1.3

Objectives of Accounting

The chapter lists what accounting is for. As commonly taught, the objectives are keeping systematic records, working out profit or loss, showing the financial position, providing information to users, protecting the business's assets, and helping with decisions. Wording and count vary a little between editions, so check them against the book you are using.

At company level the useful question is who actually delivers each one. The first three are carried mostly by the system: it records every transaction that is posted, and the profit and loss account and balance sheet come out of it at month-end. The last three need people. Providing information means someone has to read the reports and explain them. Protecting assets means watching for fraud, theft and wastage. Helping with decisions means taking the numbers and recommending what to do about them.

The first three come with a condition carried over from 1.1: the profit the system reports is only as good as the entries behind it, including the judgment-based ones that people make.

1.4

Role of Accounting

The older view treats accounting as bookkeeping, keeping the record and nothing more. The wider view, which is the one that matches what happens in a company, is that accounting is the language of business: it is how different departments talk to each other in numbers.

Take a ₹10 lakh sales order. Accounting records no revenue yet, because nothing has been delivered and the order is only a commitment. But the order sets things moving. Production needs materials, so procurement buys them, which is an ordinary purchase like the one in 1.1. Management wants to know how much cash the order will tie up and what margin it will leave. When the goods are delivered and invoiced, revenue is recorded; the cost of producing them becomes the cost of goods sold; and when the suppliers are paid, what was owed to them is cleared. Every department is working on the same order, and the accounting numbers are what let them all see it the same way. Without them, nobody would know whether the order made money or whether it put cash under strain.

1.5

Basic Terms in Accounting

The terms in this part are written for a sole proprietor, one owner running a business. In a company most of them keep their meaning and a few change shape. Going through them one at a time:

TermSole proprietorCompany
CapitalThe owner puts in their own moneyShare capital: many shareholders put in money and receive shares
DrawingsThe owner takes money out for personal useDividends: profit paid out to shareholders, decided by the board
AssetsCash, inventory, a buildingThe same, on a larger scale, with equipment and much more
LiabilitiesBank loan, amounts owed to suppliersThe same, plus things like salaries payable, owed to many more parties
RevenueMoney earned from salesThe same, with stricter rules about when it counts as earned
ExpensesSalary, rent, electricityThe same, grouped into cost of goods sold, selling and administrative expenses, and depreciation
ProfitRevenue less expensesBuilt up in layers (below)

Correction that mattered

Capital is the one that caught me out. If an investor puts ₹50 lakh into a company, what do they get? I didn't know. They get shares, a piece of the company. The money is no different from a proprietor's ₹50 lakh of capital; what changes is its form. The proprietor's capital account says ₹50 lakh, while the investor holds shares worth ₹50 lakh.

Drawings become dividends, and the difference is who decides. Take a year with ₹1 crore of profit. A sole proprietor can take out ₹50 lakh and leave the rest in the business, on their own say-so. In a company the board of directors decides, say ₹30 lakh as dividend and ₹70 lakh kept for reinvestment, through a formal process with rules around it.

Profit is where the two worlds look most different. With ₹1 crore of revenue and ₹55 lakh of costs, a sole proprietor ends with one number, ₹45 lakh before tax. A company breaks the same result into layers:

LayerHow it is worked outAmount
Gross profitRevenue less cost of goods sold (₹30 lakh of materials)₹70 lakh
Operating profit (before depreciation)Gross profit less selling and administrative expenses (₹20 lakh)₹50 lakh
EBITOperating profit less depreciation (₹5 lakh)₹45 lakh
Profit after tax (PAT)EBIT less tax (₹9 lakh); no loan in this example, so no interest₹36 lakh

The layers exist because different readers ask different questions. Operations looks at gross profit to see whether production is efficient. Management looks at operating profit to see whether the business itself is viable. Investors look at the profit after tax, the figure that is left at the end.

Two terms work the same way in both settings. A debtor is a customer who has taken goods and not yet paid, which a company's books show as accounts receivable. A creditor is a supplier we have bought from and not yet paid, shown as accounts payable.

Closing

Does It Hold at Company Level?

What carries over is the idea rather than the way it is carried out. A system performs the routine steps, and a person's value moves to the judgment-based entries and to reading, explaining and communicating the numbers.

Mostly yes. The seven steps are the same, but a system performs the routine ones and a person's value moves to the judgment-based entries and to reading, explaining and communicating the numbers. The users are the same two groups, and they get two different reports. The objectives are the same, with about half delivered by the software and half by people. The role is wider than record-keeping because every department talks in these numbers. And the vocabulary needs translating at exactly the point where one owner becomes many shareholders: capital turns into share capital, drawings into dividends, and a single profit figure into a ladder of them. I haven't tested every term in the chapter this way, only the ones above, so I'd treat the rest as unchecked.
