E-commerce is the one category where the build price is often the least important number. A store that costs ₹2 lakh to build but bleeds 3% on every transaction and loses customers at checkout is far more expensive than one costing ₹5 lakh that converts well and charges 2%.
So this guide covers both: what stores cost to build in Bengaluru, and the running economics that determine whether yours is actually profitable.
Build cost by platform
| Approach | Build cost | Monthly platform cost | Best suited to |
|---|---|---|---|
| Shopify (custom theme) | ₹80,000 – ₹2,50,000 | ₹2,500 – ₹25,000 | D2C brands, fast launch |
| WooCommerce | ₹1,00,000 – ₹3,50,000 | ₹1,500 – ₹8,000 | Content-heavy stores, tight budgets |
| Custom build | ₹3,00,000 – ₹12,00,000 | ₹3,000 – ₹30,000 | Unusual workflows, ERP integration |
| Multi-vendor marketplace | ₹8,00,000 – ₹25,00,000 | ₹10,000 – ₹60,000 | Marketplace platforms |
The running costs that decide profitability
Model these before you choose a platform, not after. For a store doing ₹10 lakh a month in revenue:
Return-to-origin is the silent killer of Indian e-commerce margins. Cash-on-delivery orders are refused at the door at rates of 15–30% in many categories, and you pay shipping both ways. Building COD confirmation via WhatsApp or OTP into your checkout is one of the highest-ROI features you can commission.
Features that actually move revenue
Not all features earn their build cost. Based on what consistently pays back for Indian stores:
Worth building early
- Fast, single-page checkout with UPI
- COD confirmation via WhatsApp or OTP
- Abandoned-cart recovery messages
- Accurate stock and delivery estimates
- Fast product search with filters
- Order tracking that customers can self-serve
Usually can wait
- Loyalty and points programmes
- AR or 3D product previews
- Multi-currency (before you have export demand)
- Elaborate wishlist and social features
- Custom recommendation engines
- Native mobile app (a fast site usually beats it early)
The checkout is where money is lost
Indian cart abandonment averages well above 65%. Most of that is decided in the final two screens. The fixes are unglamorous and effective:
- Do not force account creation Guest checkout alone routinely lifts conversion by double-digit percentages.
- Put UPI first It is the dominant Indian payment method and has the lowest friction. Burying it under card fields costs you orders.
- Show the final price early Shipping charges appearing at the last step is the single most cited reason for abandonment.
- Autofill address from pincode Reduces typing on mobile, where most of your traffic is, and reduces delivery failures.
- Keep it one page Every additional step loses a measurable share of buyers.
GST and compliance
If you are GST-registered, this is not optional and is much cheaper to build in from the start:
- Correct HSN codes on every product
- CGST/SGST split for intra-state, IGST for inter-state orders
- Sequential, non-repeating invoice numbering
- Downloadable tax invoices for customers
- Reports that reconcile against GSTR filings
Retrofitting GST-compliant invoicing into a live store is one of the most expensive "small" changes in Indian e-commerce. Specify it on day one.
A realistic recommendation
If you are launching a D2C brand in Bengaluru and are not yet at scale, start on Shopify with a custom-designed theme — roughly ₹1,00,000 to ₹2,00,000 — and put your remaining budget into product photography and paid acquisition. Revisit a custom build once transaction fees genuinely exceed what custom development would cost to maintain.
If you already run an offline business with an ERP or complex inventory, a custom build usually pays for itself faster, because the integration is where the real operational savings are.
