Start-up Financials 101

You have the idea, maybe a co-founder, and enough conviction to quit your job or skip that campus placement. But before you write your first line of code or pitch your first customer, you need to get your financial house in order. Skipping this step does not make you move faster. It makes you move blind.

This is not a fundraising guide. This is about the boring, essential plumbing that keeps a start-up alive long enough to become a real business.

Pick a Legal Structure

In India, your main options are a Private Limited Company, a Limited Liability Partnership (LLP), or a sole proprietorship (also called One Person Company for the formally inclined). Each has different implications for taxation, liability, and fundraising.

If you plan to raise venture capital at any point, incorporate as a Private Limited Company. VCs and angel investors almost universally require it. The compliance burden is higher — board meetings, annual filings with the MCA, audited financials — but that structure is what investors and DPIIT's Start-up India registration expect.

If you are bootstrapping and want lower compliance, an LLP works well. You get limited liability protection without the overhead of board resolutions. But converting from LLP to Pvt Ltd later is not trivial, so think ahead.

Open a Current Account on Day One

Do not run business transactions through your personal savings account. Open a current account in the company's name immediately after incorporation. This is not optional — it is the foundation of clean bookkeeping.

Choose a bank that offers good digital banking, integrates with accounting software, and does not charge exorbitant fees for NEFT and RTGS. Many of the new-age banks offer start-up-friendly current accounts with no minimum balance requirements in the first year.

Get your PAN, TAN, and GST registration sorted before or immediately after opening the account. You will need the PAN for the account itself, TAN if you will be deducting TDS on any payments, and GST if your turnover will cross the threshold or if you do inter-state business.

Set Up Bookkeeping from Day Zero

The most common financial mistake start-ups make is ignoring bookkeeping until the CA asks for it at year-end. By then, half your receipts are lost, your bank statement has unexplained entries, and you are reconstructing transactions from memory.

Use accounting software from the start. Zoho Books, Tally, or even a well-structured spreadsheet will do in the early days. Record every transaction — every payment received, every expense incurred, every reimbursement to a founder. Categorise expenses into clear buckets: salaries, rent, software subscriptions, cloud hosting, travel, legal fees, and so on.

The discipline of entering transactions weekly takes thirty minutes. Reconstructing a year of transactions in March takes days and costs you your CA's goodwill.

Understand Your Runway

Runway is the number of months your start-up can survive at its current burn rate before the bank account hits zero. It is the single most important number in early-stage finance.

Calculate it simply: take your total cash in the bank, divide by your average monthly expenses (burn rate). If you have Rs 30 lakh and spend Rs 3 lakh a month, you have 10 months of runway.

Track this number monthly. When your runway drops below 6 months, it is time to either cut costs or start raising money. Fundraising takes 3 to 6 months for most start-ups, so if you wait until you have 3 months of runway, you are already in trouble.

Your burn rate should distinguish between fixed costs (rent, salaries, subscriptions) and variable costs (marketing spend, contractor payments, travel). Fixed costs are hard to cut quickly. Variable costs are your lever.

Separate Founder Money from Company Money

This is where most first-time founders get sloppy. You use your personal credit card for a business expense. You pay a vendor from your Paytm. Your co-founder buys a domain and forgets to log it. Six months in, nobody knows who spent what, and the company's books are fiction.

Set a rule: every business expense goes through the current account or a company credit card. If a founder pays out of pocket, they submit a reimbursement request with the receipt, and it gets processed through the books. No exceptions.

For founder capital contributions, document them properly. If you are putting Rs 5 lakh into the company, do it as a formal share allotment or a director's loan with a board resolution. Your future investors and auditors will thank you.

Tax Compliance Is Not Optional

Even if your start-up has zero revenue, you have filing obligations. A Pvt Ltd company must file annual returns with the MCA (Form AOC-4 and MGT-7), get its accounts audited, file income tax returns, and maintain statutory registers. Missing these deadlines attracts penalties and can lead to the company being struck off.

If you have employees, you must deduct and deposit TDS on their salaries monthly, file quarterly TDS returns, and issue Form 16 by June. If you are registered under GST, you file GSTR-1 and GSTR-3B monthly or quarterly. If you have registered under Start-up India, you may be eligible for a 3-year tax holiday under Section 80-IAC, but you still need to file the returns claiming the exemption.

Hire a CA early. Not a friend who is studying for CA finals — a practicing chartered accountant who has handled start-up clients. The cost of a decent CA for a small start-up is Rs 15,000 to Rs 40,000 per year. The cost of non-compliance is multiples of that.

Build a Simple Financial Model

You do not need a 50-tab Excel behemoth. Build a simple model that projects your revenue and expenses for the next 12 to 18 months. Include your expected revenue streams, customer acquisition costs, headcount plan, infrastructure costs, and any one-time expenses.

Update it monthly with actual numbers. The gap between your projection and reality is where you learn the most about your business. If you projected 50 paying customers by month 6 and you have 12, that is a signal — not a failure, but a signal that your assumptions need revisiting.

This model is also what investors will ask for. Not the polished pitch-deck version — the real one with your actual numbers and honest assumptions.

The Minimum Viable Finance Stack

For a start-up with fewer than 10 people, you need exactly four things: a current account with good digital banking, accounting software that your CA can access, a shared expense tracker for reimbursements, and a simple spreadsheet model for runway and projections.

That is it. You do not need an ERP. You do not need a CFO. You do not need a treasury management system. You need discipline, consistency, and a CA who picks up the phone.

Get these basics right in the first month, and you will never have to do a painful financial cleanup later. Your future self, your co-founder, your CA, and your investors will all be grateful.
