Every founder planning an ecommerce setup in India eventually hits the same wall: the storefront is the easy part. The real work — and the real risk of launch delays — sits in three areas that are easy to underestimate: payment gateway approval, GST-compliant invoicing, and shipping logistics. Get these wrong and you either can't accept payments, can't legally bill customers, or can't get orders out the door.
This checklist is written for small and mid-sized businesses — a Jaipur handicrafts brand, a Pune D2C skincare label, a Coimbatore textile wholesaler moving into B2C — that are setting up or re-platforming an online store in 2026. It is not a generic 'how to start an ecommerce business' guide. It focuses on the exact operational and compliance decisions you need to make before your first sale, in the order you'll actually need them.
Nothing here is a substitute for advice from your CA or company secretary on GST registration or tax treatment. Think of it as the practical, sequencing-focused checklist your ops team can work through alongside that professional advice.
⚡ Key takeaways
- Payment gateway onboarding in India requires business KYC, a settlement bank account, and a compliant refund/cancellation policy — start this early, it is rarely instant.
- GST invoicing rules depend on where you ship and whether you sell on your own site, a marketplace, or both — get your GSTIN and HSN codes sorted before go-live.
- Shipping costs and delivery promises should be modelled by zone (metro, Tier 2/3, and pincode-level serviceability), not as a flat national number.
- COD is still widely expected across much of India, so your gateway and courier stack both need to support it cleanly.
- A single dashboard that ties catalog, orders, payments, and shipping together reduces the manual reconciliation that usually causes launch-week chaos.
- Treat this as a sequencing checklist: legal and payment setup first, catalog and tax mapping second, shipping and courier integration last before go-live.
1Ecommerce Setup in India: What to Sequence First
Most delays in an India ecommerce launch come from doing things out of order — for instance, building the full catalog before confirming which payment gateway will actually approve the business, or shipping a product page before HSN codes are finalised. A cleaner sequence saves weeks.
- Business registration and GST registration (if applicable) — needed before you can open a payment gateway merchant account
- Bank account for settlements, ideally a current account in the registered business name
- Payment gateway application and KYC submission
- Product catalog with tax-ready HSN/SAC codes and pricing
- Shipping and courier account setup, including COD arrangements
- Policy pages: refund, shipping, privacy, terms — gateways typically ask to see these before approval
2Payment Gateways: Approval, Fees, and What Gateways Check
Indian payment gateways (the major ones support cards, UPI, net banking, and wallets) will ask for business KYC documents — PAN, GST certificate if registered, bank proof, and often a working website with visible policy pages before they approve a merchant account. Building this in parallel with your storefront, rather than after, avoids a launch-week bottleneck.
Pricing structures vary by gateway and by payment method (UPI transactions are often priced differently from card transactions), and some gateways add setup or minimum monthly fees. Compare total cost per transaction type rather than a single headline rate, since your actual payment mix (UPI-heavy vs card-heavy) will change what you actually pay.
- Confirm settlement cycle (T+1, T+2, etc.) — this affects your working capital, especially during high-order periods like festive sales
- Ask whether the gateway supports UPI AutoPay or subscriptions if you plan recurring billing later
- Check international card acceptance separately if you plan to sell to NRIs or export
- Verify chargeback and dispute handling process before go-live, not after your first dispute
- Confirm COD reconciliation support if your courier partner collects cash on your behalf
3GST Compliance for Your Online Store
If your business is GST-registered, every invoice generated by your store needs to reflect the correct GST treatment — CGST/SGST for intra-state sales, IGST for inter-state sales — mapped to the shipping address, not just the billing address. Getting this wrong is one of the most common post-launch fixes businesses have to make.
Each product needs an accurate HSN code, since the applicable GST rate is tied to it. If you sell across marketplaces as well as your own site, remember that GST compliance obligations differ slightly between marketplace-facilitated sales and direct website sales, so keep your tax mapping consistent across both channels rather than maintaining two separate logics.
- Assign HSN codes at the product level, not just at the category level
- Set up your invoicing to auto-calculate CGST/SGST vs IGST based on the customer's delivery state
- Keep GST registration details visible on invoices and on your website footer, as required
- If you register under the composition scheme, confirm with your CA whether it fits an online, multi-state selling model
- Reconcile marketplace GST reports (if applicable) against your own books monthly, not just at filing time
4Shipping and Delivery: Building a Realistic Cost and SLA Model
Shipping in India is not one number — it is a matrix of zones, weight slabs, and serviceability that varies sharply between metro pincodes and Tier 2/3 towns. A flat 'free shipping above X' promise that looks fine for Delhi-NCR orders can quietly erode margins on orders to smaller towns where courier costs and delivery times are higher.
Cash on delivery remains a significant expectation for a large share of Indian online shoppers, particularly outside metros, so your courier and payment stack both need to handle COD cleanly, including COD-to-bank reconciliation. Decide early whether you'll use a single courier aggregator or multiple regional couriers for better Tier 2/3 coverage — this decision affects your checkout page's delivery-estimate logic too.
- Map serviceable pincodes before promising delivery dates on the product page
- Model shipping cost separately for metro, Tier 2, and Tier 3/rural zones
- Decide your COD limit (order value cap) and RTO (return to origin) handling policy upfront
- Choose whether packaging and dimensional weight are factored into your courier's billing — this is a common source of surprise costs
- Set clear customer-facing SLAs for delivery and returns, and keep them consistent with what your courier can actually deliver
5Bringing Payments, GST, and Shipping Together on One Platform
The operational risk in most ecommerce setups isn't any single piece — it's the reconciliation between them. Orders come in through the storefront, payments settle through the gateway, tax needs to be calculated correctly per order, and shipping status needs to flow back to the customer. When these live in disconnected tools, small businesses end up doing this matching manually in spreadsheets, which doesn't scale past a modest order volume.
This is the practical reason to evaluate an integrated commerce platform rather than stitching together a storefront builder, a separate payment plugin, and a separate shipping tool. NUZN Commerce is built for exactly this: it helps you set up a branded online store quickly, manage catalog, orders, and payments together, and sell across web and marketplaces from one dashboard — so the payment, order, and fulfilment data you need for GST and shipping decisions sits in one place instead of three.
- Unified dashboard for catalog, orders, and payments instead of separate disconnected tools
- Sell across your own web store and marketplaces from the same order management view
- Faster setup for a branded storefront, letting you focus setup time on payments, GST, and shipping decisions
- Fewer manual reconciliation steps between what sold, what was paid, and what shipped
6Pre-Launch Checklist: Final Review Before Go-Live
Before you flip the switch on your store, run through a final review pass. This is the stage where small gaps — a missing refund policy link, an unconfigured tax rate for one state, an unverified courier pincode — get caught before customers find them.
- Test a full order end-to-end: cart, payment (including at least one UPI and one card test), invoice generation, and shipping notification
- Confirm GST invoices are generated automatically and correctly for both intra-state and inter-state test orders
- Verify COD orders trigger correct courier handoff and payment reconciliation
- Check that refund and cancellation policies are live and linked from checkout, as most gateways require
- Confirm serviceability and estimated delivery dates display correctly for a metro and a non-metro test pincode
- Have your CA or accountant do a final review of your tax setup before your first live sale
?Frequently asked questions
How long does payment gateway approval take for a new ecommerce business in India?▾
It varies by gateway and by how complete your documentation is, but it is rarely instant — plan for it to run in parallel with your storefront build, not after it. Having your GST certificate, bank proof, and live policy pages (refund, shipping, terms) ready in advance is the biggest factor in avoiding delays.
Do I need GST registration to start selling online in India?▾
This depends on your turnover, business structure, and whether you sell through marketplaces, so it's worth confirming with a CA for your specific case. Many marketplaces require GST registration regardless of turnover threshold, so if marketplace selling is part of your plan, factor that in early.
Is cash on delivery still necessary for an Indian ecommerce store in 2026?▾
COD remains a meaningful expectation for a large portion of Indian online shoppers, especially outside major metros, even as digital payment adoption keeps growing. Most businesses keep COD available with a sensible order-value cap and a clear RTO policy to manage the associated risk.
How should I estimate shipping costs before setting my pricing?▾
Build cost estimates by zone (metro, Tier 2, Tier 3/rural) rather than assuming one national average, since courier pricing and delivery times differ significantly between them. It also helps to check whether your courier bills by dimensional weight, since bulky-but-light products can cost more to ship than expected.
Can one platform handle catalog, payments, GST invoicing, and shipping together?▾
Yes — this is the core reason integrated commerce platforms exist rather than businesses stitching together separate tools. NUZN Commerce, for example, is built to manage catalog, orders, and payments from one dashboard while letting you sell across web and marketplaces, reducing the manual reconciliation that separate tools require.
