Systems and Basis of Accounting

In the previous chapter, "What Makes Accounting Information Good?", we learned that financial reports must be reliable, relevant, understandable, and comparable. But how do we actually capture the messy, day-to-day reality of a business to create those perfect reports?

Imagine you are running a busy furniture manufacturing business. In a single day, you might buy wood on credit, pay your electricity bill in cash, deliver a dining table to a customer who promises to pay next month, and take an advance payment for a custom wardrobe.

To turn this chaos into clean financial statements, an accountant has to answer two fundamental questions about every single event:

1. 1How do we record it? (The System of Accounting)
2. 2When do we record it? (The Basis of Accounting)

This chapter is about the answers to those two questions. We will look at the old, incomplete ways of doing things, and then master the modern, legally required standards: the Double Entry System and the Accrual Basis of accounting.

Part 1: The "How" — Systems of Accounting

When a transaction happens, how much of the story do you write down? Do you just jot down that cash came in, or do you record exactly where it came from and what was given in return? This choice is your "System" of accounting. There are two main systems: Single Entry and Double Entry.

The Single Entry System: The Incomplete Story

If you walk down to a local neighborhood grocery store and ask the owner how they keep their books, they will likely show you a simple diary. In that diary, they write down who owes them money, whom they owe money to, and a basic record of cash coming in and going out.

They do not keep a record of the furniture in their shop, the exact value of the goods they have sold, or a detailed breakdown of their rent and electricity expenses.

Under the Single Entry System, the business owner is only recording one side of the story for most transactions. If they pay ₹5,000 for rent, they just deduct ₹5,000 from their cash book. They don't maintain a separate "Rent Expense" account to track how much rent they've paid over the whole year.

Why do people use it? It is incredibly simple, requires no formal accounting knowledge, and is cheap to maintain. For a small street vendor or a tiny retail shop, this might be all they need to survive.

Why is it dangerous for larger businesses? Because it is incomplete, it is highly prone to errors and fraud. If cash goes missing, the books won't naturally highlight the gap because there is no cross-checking mechanism. Furthermore, because you aren't tracking all your assets and expenses properly, you cannot calculate your exact, mathematically proven net profit, nor can you create a proper Balance Sheet. You can only make an educated guess about your financial position.

The Double Entry System: The Gold Standard

In 1494, an Italian mathematician named Luca Pacioli published a book that formally described a system used by Venetian merchants. This system revolutionized commerce and is still the exact same system used by every major corporation in the world today. It is called the Double Entry System.

The core philosophy of Double Entry is simple but profound: Every transaction has two sides. You cannot receive something without giving something away. You cannot create a liability without acquiring an asset or incurring an expense.

Let's look at how this works in real life.

Imagine your furniture business buys a new delivery truck for ₹5,00,000 in cash.

• In a Single Entry system, you would just write: "Minus ₹5,00,000 from cash."
• In the Double Entry system, you recognize two effects:

1. 1Your cash balance decreases by ₹5,00,000.
2. 2Your vehicle assets increase by ₹5,00,000.

Imagine you buy ₹50,000 worth of wood from a supplier on credit.

• Effect 1: Your stock of raw materials (an asset) increases by ₹50,000.
• Effect 2: Your debt to the supplier (a liability) increases by ₹50,000.

Because every transaction is recorded with these two equal balancing effects, the total of all the "receiving" aspects (which accountants call Debits) will always exactly equal the total of all the "giving" aspects (which accountants call Credits).

Comparing Single Entry vs. Double Entry

To make the distinction crystal clear for the exam, here is how the two systems stack up against each other:

• Completeness of Records:
• Single Entry: Incomplete. Only cash and personal accounts are kept.
• Double Entry: Complete. All accounts (personal, real/assets, nominal/expenses) are maintained.
• Error Checking (Trial Balance):
• Single Entry: You cannot prepare a Trial Balance to check mathematical accuracy.
• Double Entry: You can easily prepare a Trial Balance. If it balances, your arithmetic is correct.
• Financial Statements:
• Single Entry: You cannot prepare a true Trading and Profit & Loss Account or a Balance Sheet. You prepare a "Statement of Affairs" which is just an estimate.
• Double Entry: You can prepare exact, reliable financial statements.
• Legal Recognition:
• Single Entry: Not recognized by tax authorities or company law.
• Double Entry: Legally recognized and mandated for registered companies.

Part 2: The "When" — Basis of Accounting

Now that we know how to record a transaction (using Double Entry), we face a trickier question: When exactly does a transaction happen?

Suppose you own a commercial building and rent it out to a tenant for ₹10,000 a month. The tenant lives there for the whole month of December. However, they are traveling, so they don't actually hand you the ₹10,000 cash until January 15th.

In which year did you earn that income? Did you earn it in December (when you provided the space) or in January (when you touched the cash)?

Your answer depends on your Basis of Accounting. There are two main bases: Cash Basis and Accrual Basis.

The Cash Basis of Accounting: Timing = Cash

The Cash Basis is the most intuitive way to think about money. Under this method, a transaction is completely ignored until cash actually changes hands.

Let's look at our landlord example. Under the Cash Basis:

• In December, you record nothing. Even though the tenant used your building, no cash moved.
• In January, when the tenant hands you the ₹10,000, you record the income.

Who uses the Cash Basis? Professionals like doctors, lawyers, and small independent contractors often use the cash basis. If a doctor sees a patient in March but the patient pays the bill in April, the doctor treats it as April's income. It is simple, and it ensures you never pay tax on money you haven't actually collected yet.

The Problem with Cash Basis: It gives a distorted view of profitability. Imagine you run a business that buys goods in Year 1 (paying cash) but sells them on credit, only collecting the cash in Year 2. Under the Cash Basis, Year 1 will look like a massive disaster (huge expenses, zero income). Year 2 will look like a miracle (zero expenses, huge income). Neither year reflects the true performance of the business.

The Accrual Basis of Accounting: Timing = Event

To fix the distortions of the Cash Basis, the accounting profession developed the Accrual Basis. This is the method used by almost all modern businesses.

The core idea here is the Matching Principle. If you earn revenue in a specific year, you must record all the expenses related to earning that revenue in the same year, regardless of when the cash actually moves. You match the effort (expense) to the reward (revenue).

Let's revisit the landlord example under the Accrual Basis:

• In December, the tenant uses the building. You have earned the rent. You record ₹10,000 as income in December, and you record that the tenant owes you money (an asset called a debtor or receivable).
• In January, when the tenant pays the cash, you do not record income again. You simply record that the asset (the debt owed to you) has been converted into another asset (cash).

The Four Pillars of Accrual Accounting

Because the Accrual Basis separates the event from the cash flow, it creates four specific situations that you must understand perfectly for the exam. These are the adjustments that make accrual accounting work.

1. Outstanding Expenses (Incurred but not paid)

You used the electricity for your factory in March. The bill arrives on April 5th, and you pay it on April 10th. Because you consumed the electricity in March, it is a March expense. At the end of March, you must record this as an Outstanding Expense. It is a liability because you owe the money for a service you have already consumed.

2. Prepaid Expenses (Paid but not incurred)

You buy a one-year fire insurance policy for your warehouse on October 1st and pay ₹12,000 in cash. Your financial year ends on December 31st. By December 31st, you have only "used up" 3 months of that insurance (Oct, Nov, Dec). The remaining 9 months (₹9,000) is a Prepaid Expense. You paid the cash, but you haven't consumed the benefit yet. Therefore, that ₹9,000 is not an expense for this year; it is an asset (a benefit you own for the future).

3. Accrued Income (Earned but not received)

You hold ₹1,00,000 in a bank fixed deposit that pays 10% interest annually. The bank will credit the interest to your account next year. However, by the end of this year, your money has been sitting there earning interest. You have earned it, even if you can't withdraw it yet. This is Accrued Income. It is recorded as income for this year, and it sits on your balance sheet as an asset (money owed to you).

4. Unearned / Advance Income (Received but not earned)

A customer pays you ₹50,000 in advance to build custom furniture for them next year. You have the cash in your hand today. Under accrual accounting, this is not your income yet. You haven't done the work. If you fail to build the furniture, you have to give the money back. Therefore, Unearned Income is treated as a liability. It only becomes income next year when you actually build and deliver the furniture.

The Legal Standard: The Indian Companies Act

You might wonder, can a business just choose whichever basis it likes?

If you are a sole proprietor or a partnership, you generally have the freedom to choose (though tax authorities strongly prefer accrual). However, if you are a registered company, the law makes the choice for you.

This is a crucial point. The Indian government and regulatory bodies recognize that only the combination of Double Entry and Accrual Basis provides a true and fair view of a company's financial health. Cash basis and Single entry are legally invalid for registered companies in India.

Comparing Cash Basis vs. Accrual Basis

Let's summarize the differences clearly:

• Recording of Transactions:
• Cash Basis: Records only cash inflows and outflows. Ignores credit transactions entirely until settled.
• Accrual Basis: Records both cash and credit transactions as soon as they occur.
• Matching Principle:
• Cash Basis: Does not follow the matching principle. Expenses and revenues of different periods get mixed up based on when cash moves.
• Accrual Basis: Strictly follows the matching principle. Expenses are matched to the revenues they helped generate in the same period.
• Reliability and Accuracy:
• Cash Basis: Less reliable. Can be easily manipulated by delaying or speeding up cash payments at year-end.
• Accrual Basis: Highly reliable. Reflects the true operational performance of the business.
• Legal Acceptability (Companies Act, 2013):
• Cash Basis: Not accepted for companies.
• Accrual Basis: Compulsory for all registered companies.

(Note: You may occasionally hear about a "Hybrid" or "Mixed" basis, where a professional might record income on a cash basis to avoid paying tax on uncollected fees, but record expenses on an accrual basis to claim deductions early. While this exists in practice for some individuals, it is not a standard recognized by the Companies Act or standard accounting principles for corporate reporting.)

Worked Example: Seeing the Difference in Action

To truly master this for the exam, let's look at a complete scenario and calculate the profit under both the Cash Basis and the Accrual Basis.

The Scenario: Rahul starts a consulting business in Year 1. During Year 1, the following things happen:

1. 1He provides consulting services worth ₹8,00,000 to clients.
2. 2Out of this ₹8,00,000, clients pay him ₹6,00,000 in cash during Year 1. The remaining ₹2,00,000 will be paid in Year 2.
3. 3He incurs total office expenses (rent, internet, travel) of ₹3,00,000 for the year.
4. 4He pays ₹2,50,000 of these expenses in cash. The remaining ₹50,000 is outstanding (he will pay it in Year 2).
5. 5He pays ₹40,000 in cash for a software subscription that covers Year 2 (paid in advance).

Let's calculate Rahul's profit for Year 1 under both methods.

Calculation under Cash Basis

Under the Cash Basis, we put on our blinders. We ONLY look at cash moving in and cash moving out during Year 1.

• Cash Inflows (Revenues): ₹6,00,000 (We ignore the ₹2L owed to him).
• Cash Outflows (Expenses): ₹2,50,000 (office expenses paid) + ₹40,000 (software paid in advance) = ₹2,90,000. (We ignore the ₹50K he owes).
• Net Profit (Cash Basis): ₹6,00,000 - ₹2,90,000 = ₹3,10,000.

Calculation under Accrual Basis

Under the Accrual Basis, we ignore the cash movements and look at what was actually earned and incurred in Year 1.

• Revenues Earned: ₹8,00,000 (He did the work, so he earned the full amount, regardless of cash received).
• Expenses Incurred: ₹3,00,000 (He consumed these office services in Year 1. We include the outstanding ₹50K. We completely exclude the ₹40K software payment because that is a Prepaid Expense for Year 2, not an expense for Year 1).
• Net Profit (Accrual Basis): ₹8,00,000 - ₹3,00,000 = ₹5,00,000.

The Verdict: Look at the massive difference! The Cash Basis says Rahul made ₹3.1 Lakhs. The Accrual Basis says he made ₹5 Lakhs. The Accrual Basis is the correct reflection of his business performance because his actual effort in Year 1 generated ₹8 Lakhs of value, and it cost him ₹3 Lakhs of resources to do it. The timing of the cash is just a treasury management issue, not a measure of profitability.

Quick Revision

Before you close this chapter, make sure you can recall these high-yield points:

• Single Entry System: Incomplete records. Only maintains Cash and Personal accounts. Cannot produce a Trial Balance or a true Balance Sheet.
• Double Entry System: Based on the Dual Aspect Concept. Every transaction has equal Debits and Credits. Allows for mathematical proof of accuracy (Trial Balance).
• Cash Basis: Records transactions only when cash is received or paid. Ignores credit transactions. Does not follow the matching principle.
• Accrual Basis: Records revenues when earned and expenses when incurred, regardless of cash flow. Follows the matching principle.
• Outstanding Expense: Expense incurred but not paid (Liability).
• Prepaid Expense: Expense paid but not yet incurred (Asset).
• Accrued Income: Income earned but not yet received (Asset).
• Unearned/Advance Income: Income received but not yet earned (Liability).
• The Law: Section 128 of the Companies Act, 2013 mandates that all companies must use the Double Entry System and the Accrual Basis of accounting.
