Why Most Shopify Stores
Plateau and Stay There.
Here's the reality. Most Shopify development agencies are theme shops. They pick a template, drop in your products, change the colours, and ship it. Six weeks later you have a store that looks fine but converts at 1.2%. You keep spending on ads. The CAC climbs. The agency says “that's normal.”
It's not normal. It's a build problem.
Your store looks great on desktop and breaks on mobile
That’s where 65% of your traffic actually lands. And where most of your revenue is leaking.
You’re running paid ads to a store that wasn’t built to convert
Every pound or dollar you spend on Meta or Google is hitting a product page with no CRO thinking behind it.
Three vendors, zero accountability
One for dev, one for design, one for ads — and when revenue doesn’t move, everyone points at someone else.
You’ve been burned by an offshore agency before
Late delivery, poor communication, a store that needed rebuilding 12 months later. We’ve heard this story constantly.
We've heard all four of these. A lot. Which is why we built BillionX differently.
Shopify Development That's
Engineered for Revenue, Not Just Aesthetics.
We're a Shopify development company, yes. But everything we build is run through one filter: will this make the store more money? Every page structure, every checkout flow, every speed decision is made with conversion rate in mind — not just what looks good in a Figma mockup.
Shopify Plus Development & Custom Builds
If you’re on standard Shopify and hitting its ceiling, we migrate you to Plus without losing a single SKU, redirect, or review. Starting from scratch? We architect the store properly — scalable structure, clean code, zero theme bloat. No pre-built themes used as shortcuts. Every section is purpose-built for your catalogue, your customer, and your conversion goals.
Headless Shopify — Hydrogen & Next.js
Standard Shopify hits performance limits at scale. Headless decouples the frontend from the backend — faster load times, better Core Web Vitals, and a completely custom UX not constrained by Liquid. We build headless on Shopify Hydrogen and Next.js. Best for brands doing $1M+ who want sub-2-second load times and a checkout experience built around their customers.
Custom Theme Development & Redesigns
Sometimes you don’t need a full rebuild — you need a store that actually looks like your brand and works like it should. We take any existing theme (Dawn, Prestige, Impact, custom) and redesign it to convert. That means restructuring page layouts, rebuilding product pages, fixing mobile UX, and A/B testing sections — not just changing hex codes.
Shopify Speed & Core Web Vitals Optimisation
A 1-second delay in page load costs 7% in conversions — that’s Google’s own data. We audit your Core Web Vitals (LCP, CLS, FID), remove script bloat, optimise images, implement lazy loading, and get your PageSpeed score into the 90s. Faster stores rank higher and convert better. Two wins for the same work.
App Integrations, Klaviyo & Automation Stack
A Shopify store is only as powerful as the apps wired into it. We integrate and configure Klaviyo (email flows, abandoned cart, post-purchase sequences), Recharge (subscriptions), Yotpo/Okendo (reviews), AfterShip (returns and tracking), and custom webhook automations connecting your store to your 3PL, CRM, or ERP. No broken integrations. No data gaps.
Shopify Migration — WooCommerce, Magento, BigCommerce
Moving platform is high-risk if done wrong. We’ve migrated stores from WooCommerce, Magento 2, BigCommerce, and Wix to Shopify Plus — with full data migration (products, customers, orders, reviews), 301 redirects mapped and tested, and zero drop in organic traffic post-launch. We know exactly where migrations go wrong. And exactly how to prevent it.

From 1.2% to 3.1% CVR. 60 Days.
A US-based apparel brand came to us after two previous Shopify agencies left their store with a 1.2% conversion rate and a 7-second mobile load time. We rebuilt the product pages, restructured the checkout flow, and optimised Core Web Vitals. 60 days later: 3.1% CVR, sub-2s load time, 31% increase in mobile revenue.

We Work With.
We're not the right fit for everyone — and we'd rather be honest about that upfront. Here's who we do our best work with.
You’re doing $500K–$10M and you’ve outgrown your current store
Your revenue is real, your traffic is growing, but the store itself is the bottleneck. Pages are slow, the mobile UX is clunky, and your conversion rate hasn’t moved in 12 months. You need a proper rebuild — not a refresh. This is the project we do most.
You’re launching on Shopify Plus or migrating from another platform
You’ve hit Shopify’s limits or you’re moving from WooCommerce/Magento and you want to do it right the first time. We migrate your data, rebuild your store architecture, and get you live without touching your SEO rankings.
You’re an agency that needs a Shopify delivery team
You have the client relationship. We have the Shopify expertise. We work as your invisible delivery partner — under your brand, at your timelines. US and UK agencies use us regularly because we’re fast, communicative, and don’t drop the ball.

Before Working With Us.
We’re a Shopify Partner agency with verified history on Shopify Plus builds. We share live store portfolio links during the audit call — we’d rather show you a working store than a case study PDF.
Most offshore Shopify projects fail for two reasons: poor scoping and poor communication. We address both directly. Every project starts with a 2-week architecture sprint — no code until structure is signed off. You get weekly video demos throughout the build. Dushyant, the founder, is personally on every project. You’re not handed to a junior team.
A custom Shopify build typically takes 6–10 weeks depending on complexity. A headless Shopify build on Next.js usually takes 10–14 weeks. A WooCommerce or Magento migration is typically 4–6 weeks. You get a fixed timeline and a fixed scope at the start — no surprises.
