Shopify, WooCommerce or custom: how platform affects cost
Each platform shifts costs between the build and the running of your store.
| Shopify | WooCommerce | Custom store | |
|---|---|---|---|
| Build effort | Quickest to launch | Moderate; highly flexible | Highest |
| Ongoing platform costs | Monthly subscription plus paid apps | Hosting plus any paid extensions | Hosting and development time |
| Control | Within Shopify's limits | Full control of your site and data | Complete control |
| Best for | Fast launch and simple management | Content-led stores already on WordPress | Complex catalogues or unique workflows |
What decides your online store cost
These eight factors explain most of the difference between quotes.
Number of products
Ten products and ten thousand are different builds. Bulk upload and catalogue structure take time.
Variants and options
Sizes, colours, bundles and custom options add logic to product pages and inventory.
Payment methods
UPI, cards, wallets, net banking and cash on delivery each need setup and testing. See payment gateway integration services in Kolkata.
Shipping and couriers
Rate rules, pincode checks and courier integrations change checkout and order flow.
Integrations
Accounting, GST invoicing, CRM and ERP links reduce manual work but add build time.
Design customization
A tuned theme costs less than a fully custom storefront designed around your brand.
Migration
Moving products, customers and orders from an old store needs planning to protect SEO.
Speed and SEO
Fast category pages and clean structure matter more as your catalogue grows.
Costs of running an online store after launch
The build is a one-time cost. These keep the store running and growing.
Platform subscription
Shopify charges a monthly plan. WooCommerce is free software but needs hosting.
Payment gateway fees
Gateways take a percentage per transaction. This goes to the gateway, not to the build.
Apps and plugins
Reviews, subscriptions, shipping and email tools may carry licence fees.
Maintenance
Updates, backups, security and speed checks. Care plans start at ₹5,000 a month.
Content and photography
Product photos and descriptions directly affect sales.
What Indian online stores need
Stores for Indian shoppers have local needs that affect scope and cost.
- GST-ready invoices: orders that produce correct tax invoices.
- UPI and cash on delivery: payment options Indian shoppers expect.
- Courier integrations: pincode checks and shipping rates at checkout.
- Easy returns: clear policies and a simple return flow build trust.
- Mobile speed: most shoppers browse and buy on their phones.
Is an online store worth the cost? An example
This is an illustrative example, not a client result. Assume a store gets 2,000 visits a month and 2% of visitors buy. That is 40 orders. At an average order of ₹1,500, the store brings in ₹60,000 a month.
Now suppose a faster, better-structured store lifts conversion from 2% to 2.5%. That is 50 orders and ₹75,000, which is ₹15,000 more every month from the same traffic. Small conversion gains compound, which is why speed and checkout design matter. Use your own visits, conversion rate and order value to estimate yours.
How to lower your store cost
- Launch with your best-selling products and add the rest in phases
- Prepare product photos, descriptions and prices before the build starts
- Choose one platform and avoid adding features you will not use in year one
- Start with the payment methods your customers already use
- Agree the scope in writing so extra requests are priced before they happen
How we build your online store
A clear process keeps cost and timeline predictable.
1. Discovery and catalogue planning
We map your products, variants, payment methods and shipping rules, then confirm scope and timeline.
2. Store design
We design the storefront, product pages and checkout, and get your sign-off before development.

We set up the platform, payment gateway, inventory and order flow, and connect the tools you use.
4. Testing and launch
We test orders, payments and speed on real devices, then launch with tracking in place.
Signs your store needs a rebuild
If several of these sound familiar, a new store usually pays for itself.
- Your store takes more than 3 seconds to load on mobile
- Shoppers add to cart but abandon at checkout
- Managing stock and orders takes hours of manual work
- Your site looks dated next to competitors
- You are outgrowing your current platform
