New Seller Roadmap: Every Phase to Launch Your Online Business in India
A phase-by-phase roadmap for first-time online sellers in India — what to register and file, with free quizzes, calculators, and guides for each step.
Last reviewed:
Most guides to "starting an online business in India" throw every step — legal, marketplace, pricing, logistics, tax — into one long page. That's useful once you're deep in it, but overwhelming on day one, when the real question is simpler: what do I actually need to do first, and in what order?
This page is a roadmap, not another guide. It breaks the journey into six phases below — from "should I even register?" to "how do I scale once this works" — and for each phase points you to the one quiz, calculator, or guide that answers that specific question, rather than making you read everything before you can act.
Work through the phases in order if you're starting from zero. If you're already selling, jump straight to the phase that matches where you are.
Is This Right For You?
Before you pick a business structure or a marketplace, confirm the two things that determine everything downstream: whether GST applies to you, and what legal structure fits.
Checklist for this phase
- Confirmed whether GST registration is mandatory for you
- Decided on a starting business structure (sole prop is fine for almost everyone at this stage)
Legal & Registration Setup
With your structure decided, get the paperwork done before you touch a marketplace signup form — every platform will ask for your GSTIN during onboarding.
Checklist for this phase
- GST registration filed and GSTIN received
- Udyam (MSME) registration completed
- Business current account opened
Pick Your Channel & Get Listed
Now choose where you'll sell and get your seller account approved.
Checklist for this phase
- Chosen your primary sales channel
- Seller account created and KYC (GSTIN, bank, PAN) submitted
- First product listing live
Price, List, and Fulfil Your First Order
Getting your first order right — pricing, invoicing, shipping — sets the pattern for every order after it.
Checklist for this phase
- Verified your net margin per order using the profit calculator
- Confirmed your invoices meet GST format requirements
- Fulfilment method chosen (marketplace FBA or self-ship via aggregator)
Stay Compliant Every Month
Once you're selling, compliance becomes a recurring task, not a one-time setup. This is the phase most new sellers underestimate — a missed GST return triggers late fees even in a month with zero sales.
Checklist for this phase
- First GSTR-1 and GSTR-3B filed
- Filing due dates added to your calendar
- Confirmed which ITR form applies to you before filing season
Grow & Scale
Once the basics are running smoothly, the questions shift — multiple states, funding, and whether the business is actually profitable once every cost is counted.
Checklist for this phase
- Reviewed whether you need APOB (Additional Place of Business) registration in new states
- Confirmed your actual net profitability, not just topline sales
- Explored funding options if working capital is the bottleneck
