Template vs. built
Two ways to get a store. Only one you can scale.
Typical template store build
- A bought theme with the demo content swapped out
- Plugin stack for every feature, breaking on updates
- Checkout untested on real payment and COD cases
- No analytics or commerce events before launch
- Handover is a login and a zip file
ACSIUS eCommerce build
- Design system built around your catalogue and margins
- Custom code where plugins would slow the store
- Checkout, payment, COD and returns cases QA'd
- GA4, CAPI and funnel baseline live before cutover
- Repo, docs and admin ownership from day one

eCommerce development, answered.
Send your catalogue size and target launch date. You get a platform recommendation, milestone plan and written cost inside two working days.
Request a ProposalDiscovery and platform selection, eCommerce website design for home, category, product, cart and checkout, front-end and back-end development, payment gateway and shipping integrations, ERP or 3PL sync, product data import, SEO structure and schema, analytics with commerce events, QA across devices, launch support and a post-launch CRO backlog.
Shopify or Shopify Plus suits DTC brands that want the fastest launch, WooCommerce fits content-led stores already on WordPress, Adobe Commerce or Magento suits large catalogues and multi-store B2B retail, and a headless Next.js or Hydrogen storefront makes sense when performance is your differentiator. We recommend a platform in writing after the discovery call, based on catalogue size, margins and your team's skills.
A focused Shopify or WooCommerce launch usually starts in the low five figures in rupees per milestone, while multi-store Magento or headless builds are quoted after scoping. You get a fixed milestone cost for the launch and an optional monthly care plan; every change outside scope is priced in writing before work starts.
A clean Shopify or WooCommerce store typically launches in three to seven weeks, and Magento or headless builds run eight to fourteen weeks depending on catalogue size and integrations. Design starts in week one and you get a preview URL every week, so nothing is a surprise at the end.
Yes. We move products, customers, orders and reviews, rebuild URL structures where possible and test a full 301 redirect map on staging before DNS changes. Rankings, crawl errors and revenue are monitored for 30 days after cutover, and rollback steps are documented in the launch runbook.
We are an in-house team in New Delhi working on commerce since 2010, with designers, platform developers, QA and SEO under one roof. You get India rates with at least four hours of timezone overlap, daily written updates, code in your repository from day one, custom code instead of a plugin pile-up, and 30 days of support after launch.
