Most people overcomplicate this. You don't need a company, a fancy office, or a lawyer on retainer to start selling online. You need a legal identity to receive money, and a handful of registrations that unlock the rest. This guide lays them out in the order a real seller hits them.
A quick honest note first: this is educational, not legal or tax advice. Thresholds, fees and rules change often, and your situation may differ. Treat the sections below as a map, then confirm current specifics with a CA or the official portals before you file.
Pick your structure: proprietorship, LLP or Pvt Ltd
Your legal structure decides how you pay tax, how much paperwork you carry, and how you raise money later. Nine out of ten first-time online sellers should start as a sole proprietorship - it is the cheapest and fastest to run.
A proprietorship isn't a single registration; it's simply you, trading under a business name. You establish it by opening a current account and getting a couple of registrations (usually GST and/or Udyam) in the business name. There's no separate incorporation, no MCA filing, no annual company compliance. The trade-off: no liability protection, and the business income is your personal income.
Move up only when there's a reason. An LLP suits two or more partners who want limited liability without heavy compliance. A Private Limited company makes sense if you plan to take outside investment or issue equity to a co-founder - but it comes with mandatory audits, ROC filings and a CA's ongoing involvement.
- Sole proprietorship: solo seller, lowest cost, minimal compliance, no liability shield.
- Partnership / LLP: two or more owners, moderate compliance, LLP adds limited liability.
- Private Limited: for outside funding or equity, highest compliance and cost.
- You can start as a proprietor and restructure later once volumes justify it.
GST registration: often unavoidable for online selling
GST is where online sellers differ from a corner shop. The general turnover thresholds (commonly cited around ₹40 lakh for goods and ₹20 lakh for services, lower in some special-category states) let small offline traders stay unregistered. But the moment you sell inter-state, and especially if you list on marketplaces, GST registration is typically required regardless of turnover.
If you're selling only from your own website within your own state and staying under the threshold, you may not need it immediately - but many payment gateways and B2B buyers ask for a GSTIN anyway. Rules here shift, so confirm the current position for your exact case before deciding to skip it.
Registration is free on the GST portal. You'll need PAN, Aadhaar, a business address proof, bank details and photos. Once registered, you must file returns on schedule even in months with zero sales - missing them attracts late fees.
- Selling on marketplaces (Amazon, Flipkart, Meesho) generally requires a GSTIN.
- Inter-state sales usually trigger mandatory registration irrespective of turnover.
- Registration is free; the ongoing cost is timely return filing.
- Verify current thresholds - they have changed several times.
Udyam (MSME) registration: quick, free, worth it
Udyam is the government's MSME registration, done online in minutes using your Aadhaar and PAN. It's free and self-declared. There's little downside to registering, and a few real upsides.
The benefits that matter most to small sellers: eligibility for priority-sector lending and certain collateral-free loan schemes, protection under delayed-payment rules when you supply to larger buyers, and easier access to some government tenders and subsidies. It also serves as clean proof that your business exists - useful when opening accounts or applying for other registrations.
- Free, Aadhaar-based, takes a few minutes online.
- Helps with business loans and priority-sector credit.
- Gives you recourse under MSME delayed-payment provisions.
- Acts as simple official proof of your business.
Sector licences: FSSAI and others
Some trades need a licence before you can legally sell. The big one for online sellers is FSSAI, mandatory for anyone handling food - packaged snacks, homemade pickles, bakery, spices, supplements, even reselling food items. A basic FSSAI registration covers small turnovers; larger operations need a State or Central licence. Displaying your FSSAI number is required on food listings and packaging.
Other trades have their own rules: cosmetics and ayurvedic products, drugs, and certain electronics or imported goods can attract specific approvals. If you sell anything ingestible, applied to skin, or safety-regulated, check whether a licence applies before you launch, not after.
- FSSAI: mandatory for all food businesses, including home kitchens and resellers.
- Cosmetics, wellness and imported goods may need separate approvals.
- Check sector rules early - retrofitting compliance is expensive.
Open a current account and separate your money
Keep business and personal money apart from day one. It makes GST filing, income tax and any future loan application dramatically simpler, and it looks professional when customers pay you.
Banks typically ask for your GST certificate or Udyam registration, PAN, address proof and KYC to open a current account in the business name. A proprietor can often open one with GST or Udyam plus a shop/business proof. Ask two or three banks about minimum balance requirements and transaction limits - these vary widely and eat into thin margins if you pick wrong.
Pair the account with a payment gateway so you can accept UPI and cards online. Gateways charge a per-transaction fee on prepaid orders, and they'll want your registration documents during onboarding.
Get your storefront live while the paperwork moves
Registrations take days to weeks. Your website doesn't have to wait. You can build and start showing products in parallel, then switch on prepaid payments once your gateway and GST are sorted - COD can run in the meantime.
This is where Kartrocket fits. It's Shiprocket's chat-native business builder: you describe your business in plain language, Hinglish included, and a working store builds itself live. It's free to build and free to publish on a yourname.kartrocket.ai address with SSL, and you can connect your own domain later. Checkout supports COD, UPI and cards, shipping runs on Shiprocket across 24,000+ pincodes with tracking, and prices are computed on the server so checkout can't be tampered with. You pay only real pass-through costs - courier charges, payment-gateway fees on prepaid orders, and your domain if you bring one.
Practically, that means you can validate demand and take a few orders while your GSTIN and current account come through, instead of losing weeks.
When to bring in a CA
You can self-file GST and Udyam. But there are moments where a chartered accountant pays for themselves: choosing between LLP and Pvt Ltd, setting up company incorporation, structuring GST for multiple states or high volumes, and handling your first income-tax return as a business.
A one-time consultation early on is cheap insurance. Even if you run day-to-day yourself, get a professional to confirm your structure and GST position match your actual sales pattern - mistakes here are far costlier to unwind later.
