Accounting Basics for Indian Business Owners
You built a business from scratch. You manage people, clients, vendors, and deadlines every single day. But ask you what your net profit was last month, and you probably have to call your accountant to find out.
You're not alone. And it's not your fault.
Accounting is one of those subjects that school completely ignores for most people. Commerce students get a version of it — heavily theoretical, exam-focused, disconnected from real business. Science and arts students get nothing at all. And then one day, you register a company, get a GST number, and suddenly, you're responsible for a financial system you were never taught to understand.
This guide fixes that. It covers everything a business owner in India needs to know about accounting — not to replace your CA, but to understand what's happening in your own business. Because when you understand your numbers, you make better decisions, catch problems earlier, and stop being completely dependent on someone else to tell you if your business is healthy.
No jargon. No theory for its own sake. Real examples. Indian context throughout.
Let's start from zero.
What Is Accounting, Really?
At its simplest, accounting is the practice of recording every financial event in your business and organising those records so you can understand what happened.
Every time money moves — a customer pays you, you pay a vendor, you buy equipment, you pay salaries — that's a financial event. Accounting is the system that captures it all, puts it into the right buckets, and turns it into information you can actually use.
Think of it like this. Imagine your business is a tank with water flowing in and out. Money comes in from customers. Money goes out to vendors, employees, rent, and taxes. If you don't track the flow carefully, you won't know whether the tank is filling or emptying — until it runs dry.
Accounting is the flowmeter on that tank.
The output of good accounting is three things:
- Knowing exactly how much money you made (or lost)
- Knowing exactly what you own and what you owe
- Having proof of all of it if the taxman ever asks
The Language of Accounting: Key Terms Explained Simply
Before we go further, let's clear up the terms that confuse most people. These aren't definitions for an exam — they're explanations you'll actually use.
Ledger
A ledger is simply a record of all transactions for one account. Your "HDFC Bank" ledger shows every rupee that came in and went out of that bank account. Your "Rent Expense" ledger shows every rent payment made. Every entity your business deals with — every vendor, every customer, every expense type, every bank account — has its own ledger.
Journal Entry
Every financial transaction, before it goes into any ledger, is first recorded as a journal entry. A journal entry captures what happened: the date, the amount, which ledgers were affected, and a note explaining what it was. It's the raw record of every financial event.
Debit and Credit
These two words cause more confusion than anything else in accounting. Forget what you know from your bank passbook — debit and credit there mean the opposite of what they mean in accounting.
In accounting:
- Debit means the left side of a transaction
- Credit means the right side of a transaction
That's it. They're just positions. The rule is: every transaction has a debit side and a credit side, and they must always be equal. This is called double-entry accounting, and we'll come to it shortly.
Chart of Accounts
This is the master list of all ledgers in your business, organised into categories. Every Indian business has four main categories: Assets, Liabilities, Income, and Expenses. Your chart of accounts is the filing system where every financial transaction eventually lands.
Trial Balance
A trial balance is a summary of all ledger balances at a point in time. Every ledger and its closing balance. If your accounting is correct, the total of all debit balances equals the total of all credit balances. If they don't match, something has been recorded incorrectly.
Profit & Loss Statement (P&L)
Also called an Income Statement. It shows your income minus your expenses over a period of time — a month, a quarter, a financial year. The bottom line is your net profit or net loss. This is the number most business owners care about most.
Balance Sheet
Where the P&L shows what happened over a period of time, the balance sheet shows where you stand at a specific moment. It lists everything your business owns (assets) on one side, and everything it owes (liabilities) plus what belongs to the owners (equity) on the other. A properly prepared balance sheet always balances — hence the name.
Accounts Receivable
Money that customers owe you. You've done the work or delivered the goods. They haven't paid yet. This sits as an asset on your balance sheet — it's money you're owed.
Accounts Payable
Money you owe to vendors or suppliers. You've received goods or services. You haven't paid yet. This sits as a liability on your balance sheet.
Double-Entry Accounting: The Rule That Makes Everything Work
Here's the single most important concept in accounting, and it's actually very logical once you see it.
Double-entry accounting says: every financial transaction affects at least two accounts, always in equal and opposite ways.
Let's use a real example. You sell a tour package to a customer for ₹50,000. They pay you immediately by bank transfer.
What happened here? Two things simultaneously:
- Your bank account increased by ₹50,000 (money came in)
- Your income account increased by ₹50,000 (you earned revenue)
In accounting language:
- Debit: HDFC Bank ₹50,000 (bank accounts increase with a debit)
- Credit: Tour Income ₹50,000 (income accounts increase with a credit)
Both sides are equal. The transaction is complete.
Now, let's say you pay ₹8,000 rent for your office.
- Debit: Rent Expense ₹8,000 (expenses increase with a debit)
- Credit: HDFC Bank ₹8,000 (bank account decreases with a credit)
Again, equal on both sides.
This is the core rule of double-entry accounting. Every single transaction — no matter how complex — follows it. And because every transaction touches two sides equally, the system is self-checking. Errors surface immediately because the numbers stop balancing.
This is why your CA insists on proper accounting software rather than a spreadsheet. A spreadsheet doesn't enforce this rule. Proper accounting software does — every transaction is validated before it's saved.
The Four Pillars: Assets, Liabilities, Income, Expenses
All financial information in your business falls into one of four buckets. Understanding these four is 80% of understanding accounting.
Assets — What Your Business Owns
Cash in the bank. The money customers owe you. Equipment you've bought. Prepaid expenses. Your office furniture. The security deposit on your premises. All of these are assets — things of value that your business holds.
Assets are divided into current assets (cash and things that will convert to cash within a year — like receivables) and fixed assets (things with longer-term value, like machinery or computers).
Liabilities — What Your Business Owes
Vendor bills you haven't paid yet. GST you've collected but not yet remitted to the government. A loan from the bank. Salary you owe employees at month-end. All of these are liabilities — obligations your business has to pay.
Liabilities are divided into current liabilities (due within a year, like vendor payables and GST payable) and long-term liabilities (like a term loan due over multiple years).
Income — What Your Business Earns
Revenue from sales. Service fees. Commission income. Interest income. Any money that flows in as a result of your business activity. Income is further split into direct income (your core business revenue) and indirect income (everything else, like interest or miscellaneous receipts).
Expenses — What Your Business Spends
Rent, salaries, marketing costs, travel, software subscriptions, professional fees, and bank charges. Any money that flows out as part of running the business. Like income, expenses are split into direct expenses (costs directly tied to delivering your product or service) and indirect expenses (overhead — rent, admin, marketing, etc.).
Your P&L is simply: Income minus Expenses = Profit (or Loss).
Your Balance Sheet is simply: Assets = Liabilities + Equity.
These two equations govern everything in accounting.
The Indian Financial Year: April to March
This is basic but critical, and it's one of the first things that trips up new business owners.
In India, the financial year runs from 1st April to 31st March — not January to December like most Western countries, and some software defaults to.
This means:
- Your books open on April 1st
- Your books close on March 31st
- Your annual P&L covers April 1 to March 31
- Your income tax return is filed based on this period
- GST quarterly returns are aligned to this calendar
When you set up any accounting software, make sure the financial year start date is set to April 1. This sounds obvious, but many businesses that started with international software end up with misaligned reports because this was set incorrectly at setup.
GST: What Every Indian Business Owner Must Understand
GST — Goods and Services Tax — replaced a complicated web of central and state taxes in 2017. It's now the primary indirect tax in India, and if your business turnover exceeds ₹20 lakhs (₹10 lakhs for some states and service providers), GST registration is mandatory.
Here's what you need to understand about GST from an accounting standpoint.
You are a tax collector, not a taxpayer
This is the most important mental shift. When you charge GST to your customer, you are collecting tax on behalf of the government. That money is not yours. It sits in a liability account — GST Payable — until you remit it.
When you pay GST to your vendors, that's Input Tax Credit (ITC). The government owes you that money back, as a credit against what you owe them.
Your actual GST liability = GST collected from customers (Output GST) minus GST paid to vendors (Input GST)
If you collected ₹1,00,000 in GST and paid ₹60,000 in GST to vendors, you remit ₹40,000 to the government.
CGST, SGST, and IGST
GST splits into components based on whether the transaction is within a state or across states.
- Intra-state transaction (you and your customer are in the same state): GST splits equally into CGST (Central GST) and SGST (State GST). An 18% GST becomes 9% CGST + 9% SGST.
- Inter-state transaction (you and your customer are in different states): The entire GST is IGST (Integrated GST). An 18% GST is charged as 18% IGST.
Good accounting software determines this automatically based on the GST registration addresses. You should never have to calculate this manually.
GST Rates
The main GST slabs are 5%, 12%, 18%, and 28%. Some goods and services are exempt (0%). The rate that applies depends on what you're selling — each product or service has an HSN code (for goods) or SAC code (for services) that determines its rate.
The Three Returns You Need to Know
- GSTR-1: Filed monthly or quarterly. List all your outward supplies (sales) — every invoice you raised. Due by the 11th of the following month (monthly filers).
- GSTR-3B: Filed monthly. A summary return showing your total output tax, input tax credit, and net payment due. Due by the 20th of the following month.
- GSTR-2B: This one is different — you don't file it, you receive it. It's a statement generated by the GST portal showing all the invoices your vendors have uploaded against your GSTIN. You use it to verify your input tax credit claims.
GSTR-2B Reconciliation — Why It Matters More Than Most Businesses Realise
Every month, you need to match your GSTR-2B (what the portal says your vendors uploaded) against your purchase register (what's actually in your books).
Why? Because you can only claim ITC on invoices that appear in your GSTR-2B. If a vendor hasn't filed their GSTR-1, their invoice won't appear in your GSTR-2B — and you can't claim that ITC. Businesses that skip this reconciliation often find themselves unable to claim lakhs of rupees in legitimate input credit.
This reconciliation, done manually, can take an accountant a full day every month. It involves exporting data from the GST portal, cross-referencing with books in Excel, and identifying mismatches. Proper accounting software — like Arthastra — automates this entirely. You upload your GSTR-2B file, and the system matches every invoice, flags mismatches, and shows you exactly how much ITC is at risk.
TDS: Tax Deducted at Source
TDS is another uniquely Indian concept that confuses many business owners. Here's the plain-English version.
When you make certain payments — to contractors, consultants, professionals, or on rent above a threshold — the government requires you to deduct a percentage of the payment and deposit it directly with the Income Tax department. You pay the vendor the net amount; the tax goes to the government on their behalf.
Common TDS sections:
- Section 194C: Payments to contractors. TDS at 1% (individual/HUF) or 2% (others)
- Section 194J: Payments to professionals (doctors, lawyers, CAs, consultants). TDS at 10%
- Section 194I: Rent payments above ₹2.4 lakhs per year. TDS at 10%
Example: You hire a consultant and agree to pay ₹1,00,000. If TDS under 194J applies, you deduct ₹10,000 (10%), pay the consultant ₹90,000, and deposit ₹10,000 with the government. The consultant gets credit for the ₹10,000 TDS when they file their income tax return.
From an accounting standpoint,, You maintain a TDS Payable ledger. When you make a payment with TDS, you debit the expense, credit the vendor for the net amount, and credit TDS Payable for the deducted amount. When you deposit TDS with the government, you debit TDS Payable and credit your bank.
TDS deposits must be made by the 7th of the following month. Quarterly TDS returns (Form 26Q) must be filed. Missing these deadlines attracts interest and penalties — so a proper TDS register in your accounting system is not optional.
Bank Reconciliation: The Monthly Task Nobody Enjoys, But Everyone Must Do
Bank reconciliation is the process of matching your bank statement with what's in your accounting books — and explaining every difference.
Why do differences exist? Because of timing. A cheque you issued today may not clear the bank for three days. A payment your customer made yesterday may not reflect in tomorrow's statement. Direct debits, bank charges, and interest credits — all of these show up in the bank statement without any corresponding entry in your books until someone records them.
Bank reconciliation ensures:
- Your books accurately reflect your true bank balance
- No transactions are missing or duplicated
- Bank errors (yes, banks make errors) are caught
- Your cash position is reliable for decision-making
How it's done manually:
- Get your bank statement for the period
- Go through it line by line
- Tick off every transaction that matches an entry in your books
- What's left unticked in the bank statement = unrecorded in books (needs an entry)
- What's left unticked in your books = timing differences (outstanding cheques, deposits in transit)
Done manually, this takes 2–3 days a month for a business with moderate transaction volume.
Done with proper accounting software, it takes a fraction of the time. You upload the bank statement, the software applies matching rules automatically, and you only review the exceptions. Most accountants using automated reconciliation are done in under 3 hearnsurs.
How to Read Your Profit & Loss Statement
The P&L is the most important report in your business. Here's how to read it like a business owner, not an accountant.
A P&L has this basic structure:
Revenue (Sales / Income) ₹XX,XX,XXX
Less: Direct Expenses ₹XX,XX,XXX
———————————
Gross Profit ₹XX,XX,XXX
Less: Indirect Expenses ₹XX,XX,XXX
———————————
Net Profit (or Net Loss) ₹XX,XX,XXX
Revenue is everything your business earns — from sales, services, or any other income.
Direct expenses (also called cost of goods sold or cost of services) are costs directly tied to delivering what you sold. For a tour operator, this is the hotel cost, transport, and guide fees for each trip. For a manufacturer, these are raw materials and labour. Gross profit is what's left after covering these direct costs.
Indirect expenses are your overhead — rent, salaries of non-production staff, marketing, software, accounting fees, and electricity. These exist regardless of how much you sell.
Net profit is what actually belongs to the business after everything is paid.
Three numbers to watch every month:
- Gross Profit Margin = Gross Profit ÷ Revenue × 100. This tells you how efficiently you're delivering your product or service. If this is shrinking month over month, your direct costs are rising faster than your prices.
- Net Profit Margin = Net Profit ÷ Revenue × 100. This is your true profitability after all costs. A healthy net margin varies by industry — but if it's consistently below 5–8% for a service business, you have a cost problem.
- Month-over-month trends — a single month's P&L is less useful than three months in a row. Patterns tell you more than snapshots.
How to Read Your Balance Sheet
The balance sheet gets less attention from business owners, but it tells you things the P&L can't.
ASSETS LIABILITIES + EQUITY
—————————————————————— ——————————————————————
Current Assets Current Liabilities
Cash & Bank ₹X Accounts Payable ₹X
Accounts Receivable ₹X GST Payable ₹X
Prepaid Expenses ₹X TDS Payable ₹X
Fixed Assets Long-term Liabilities
Equipment ₹X Bank Loans ₹X
Furniture ₹X
Equity
Paid-up Capital ₹X
Retained Earnings ₹X
TOTAL ASSETS ₹X TOTAL LIABILITIES + EQUITY ₹X
Both sides must always be equal. If they're not, something has been recorded incorrectly.
What to look for as a business owner:
- Accounts Receivable — if this number is growing every month, your customers are taking longer to pay. That's a cash flow problem in the making, even if your P&L looks healthy.
- GST Payable — if this is much higher than expected, you may be under-filing or deferring payment. Interest and penalties add up fast.
- Bank balance — cross-check this against your actual bank account balance. If they don't match, your books need attention.
- Retained Earnings — this is the cumulative net profit of your business that hasn't been withdrawn. A growing retained earnings number means your business is building net worth.
The Accounting Cycle: How It All Fits Together
Now that you have all the pieces, here's how they connect in practice every month.
During the month:
- Every sale is recorded → income ledger and customer ledger updated
- Every expense is recorded → expense ledger and bank/vendor ledger updated
- Invoices are raised and sent to customers
- Vendor bills are received and entered
- Salaries are booked and paid
At month-end:
- Bank reconciliation is done — bank statement matched with books
- GST reconciliation — output GST checked against GSTR-1, input GST checked against GSTR-2B
- Outstanding receivables reviewed — who owes you money, how long overdue
- TDS payable calculated and deposited if due
- P&L and Balance Sheet reviewed
At year-end (March 31):
- All pending entries completed
- Final bank reconciliation
- Depreciation entries posted
- Closing entries passed
- Books locked for the year
- CA takes over for audit and tax filing
This cycle, repeated consistently, is what clean books look like. Most businesses that have messy books aren't doing anything wrong intentionally — they're skipping pieces of this cycle, usually the month-end reconciliation steps.
Why Business Owners Don't Understand Their Own Books — And How to Fix It
Here's something most CAs won't tell you: the accounting system is often set up for the CA's convenience, not the business owner's understanding.
The reports your CA sends you are technically correct. But they're formatted for compliance purposes, not for business decision-making. You get a P&L that lists 40 expense line items without context. You get a balance sheet that balances — great, but what does it mean for your business?
The fix isn't to become an accountant. It's to have a system that gives you the three numbers you actually need, in real time, without having to ask:
- What did I earn this month?
- What's my bank balance right now?
- Who owes me money and how much?
Modern cloud accounting platforms are designed to answer exactly these questions — for the business owner — while giving the accountant the depth and control they need to do proper books. The business owner sees a dashboard. The CA sees ledgers and vouchers.
This separation — business owner visibility on one side, accounting depth on the other — is what makes accounting useful to everyone in the business, not just the person who studied it.

Frequently Asked Questions
Do I need an accountant if I use accounting software?
Yes. Software handles recording and compliance, mechanics. An accountant handles judgment calls — how to classify a complex transaction, how to optimise tax liability, how to handle an unusual situation. Software makes your accountant faster and more accurate. It doesn't replace them.
What is the difference between bookkeeping and accounting?
Bookkeeping is the recording of transactions — entering every sale, expense, and payment. Accounting is the broader practice that includes bookkeeping plus interpretation, compliance, reporting, and financial analysis. In most small businesses, both are handled by the same person.
What is the difference between a CA and an accountant?
A CA (Chartered Accountant) is a certified professional who has passed the ICAI exams. They are licensed to audit accounts and sign off on financial statements. An accountant is a broader term — it can mean anyone who handles financial records. For most Indian SMBs, the CA handles annual tax filing and audit, while a bookkeeper or in-house accountant handles day-to-day entries.
How often should I review my P&L?
At a minimum, monthly. Many business owners look at it quarterly — by which point, problems that could have been caught in month 1 have compounded for three months. The monthly review takes 30 minutes once your books are clean. It's one of the highest-value 30 minutes a business owner can spend.
What happens if my books are not maintained properly?
In the short term, your CA will struggle to file accurate returns, and you may end up paying more tax than necessary. In the medium term, you'll face scrutiny from GST or Income Tax departments, and responding to a notice with messy books is expensive. In the long term, if you ever want funding, a loan, or to sell your business, proper audited financials are non-negotiable. Clean books from day one, avoid all of this.
Is GST applicable to all businesses in India?
GST registration is mandatory if your aggregate annual turnover exceeds ₹20 lakhs (₹10 lakhs for special category states). For businesses involved in interstate supply or e-commerce, registration is mandatory regardless of turnover. Even if below the threshold, voluntary registration can be beneficial if your customers are GST-registered businesses — it allows them to claim ITC on purchases from you.
What is the penalty for not filing GST returns on time?
Late fees apply: ₹50 per day (₹25 CGST + ₹25 SGST) for returns with tax liability, and ₹20 per day for nil returns, subject to a maximum. Interest at 18% per annum applies on the outstanding tax amount. Persistent non-filing can lead to the cancellation of your GST registration.
