eCommerce development built to convert

In eCommerce, every tenth of a second and every extra click costs you sales. At Tech Bintang LLC, our Austin-based team of 50+ builds high-performance online stores for brands in the US, UK, and Australia — storefronts that load fast, guide shoppers smoothly to checkout, and are engineered to lift conversion rate, average order value, and lifetime value.

Whether you are launching your first store, replatforming from a slow legacy site, or scaling into a multi-vendor marketplace, we combine commerce strategy with technical execution so the store does not just look good — it sells.

The problems we solve

How we build

The right platform for your stage

We build on Shopify and Shopify Plus for fast, reliable launches, WooCommerce and Magento where you need deep customisation, and fully headless commerce (Next.js with the Storefront API) when performance and bespoke UX are the priority. We help you choose based on your catalogue size, growth plans, and team — not on what is trendy.

Conversion-first design

Every decision — layout, product pages, search, trust signals, and a streamlined checkout — is aimed at removing friction between "interested" and "purchased." We add fast, relevant search and filtering (Algolia), AI product recommendations to lift average order value, and a checkout flow optimised for both desktop and mobile.

Speed as a feature

We optimise Core Web Vitals aggressively, targeting a Largest Contentful Paint under 2.5 seconds, with image optimisation, edge caching via Cloudflare, and lean front-end code. Faster stores rank better and convert more.

Integrations that run the business

We connect the systems that keep your store running: payment gateways (Stripe, PayPal, Klarna), inventory and order management, email and SMS marketing (Klaviyo), analytics, and ERP or fulfilment tools. Everything is tested end to end so orders flow cleanly from checkout to fulfilment.

Our process

We begin with a commerce audit of your funnel and drop-off points, then move through conversion-focused design, development and integrations, and performance optimisation before a carefully staged launch. After go-live we offer an ongoing CRO retainer — A/B testing, analytics, and iterative improvements that compound over time.

Choosing the right commerce platform

The platform decision shapes everything that follows, so we make it deliberately. Shopify and Shopify Plus are our default recommendation for most merchants — fast to launch, reliable, secure, and rich with apps, with Plus unlocking advanced checkout customisation for high-volume stores. WooCommerce suits businesses already invested in WordPress that want full control and no per-transaction platform fees. Magento (Adobe Commerce) fits large catalogues and complex B2B requirements. And headless commerce — a Next.js storefront powered by a commerce API — delivers the fastest, most bespoke experience when performance and brand differentiation are paramount. We help you weigh cost, speed, flexibility, and your team's capabilities before committing.

Conversion rate optimisation built in

A beautiful store that does not convert is an expensive brochure. We design every template around removing friction: fast, faceted search and filtering so shoppers find products quickly; rich product pages with clear imagery, reviews, and trust signals; persistent carts; and a checkout stripped of unnecessary steps. We add AI-driven product recommendations and cross-sells to lift average order value, and we wire up abandoned-cart recovery so you recapture revenue that would otherwise walk away.

Payments, tax, and the systems behind the store

Selling internationally across the US, UK, and Australia means handling multiple currencies, payment methods, and tax rules. We integrate the right payment gateways (Stripe, PayPal, Klarna, Apple Pay, and more), connect inventory and order-management systems, and link your store to email and SMS marketing platforms like Klaviyo so post-purchase flows run automatically. Everything is tested end to end so an order flows cleanly from "buy" to fulfilment without manual intervention.

Replatforming without losing rankings

Migrating from a slow or outdated store is one of the most common reasons clients come to us — and one of the riskiest if done carelessly. We map and preserve URLs with 301 redirects, carry over product data and metadata, retain your hard-won SEO equity, and stage the cutover so there is no downtime and no sudden drop in organic traffic. You move to a faster, better store while keeping the customers and rankings you already have.

Speed, Core Web Vitals, and SEO

In eCommerce, speed is revenue. Slow product and category pages increase bounce rates and quietly suppress your Google rankings. We optimise aggressively for Core Web Vitals — targeting a Largest Contentful Paint under 2.5 seconds — with image optimisation, lazy loading, code-splitting, and edge caching. On top of raw speed, we build in technical SEO: clean URLs, product and breadcrumb structured data, optimised titles and descriptions, and an XML sitemap, so your catalogue is discoverable and eligible for rich results in search.

Who we build for

We work with direct-to-consumer brands, retailers moving online, and B2B businesses adding eCommerce, from first launch to high-volume scale. As a US-registered company in Austin with a 50+ person team, we bring strategy, design, and engineering under one roof, with ongoing optimisation available so your conversion rate and revenue keep climbing after launch.

What you can expect

A fast, reliable store engineered to convert, with the integrations your team needs and a clear plan to keep improving conversion rate after launch. You also get a store your own team can run day to day, clean documentation, and the option of an ongoing partnership as you grow into new products, markets, and sales channels. eCommerce projects start from $6,000; after a free discovery call we provide a fixed-price proposal with scope and timeline — no hidden fees and no surprises.

FAQ

Frequently asked questions

Straight answers to the questions we hear most about ecommerce development.

Which eCommerce platform is best for my business?

It depends on your catalogue, customisation needs, and growth plans. Shopify and Shopify Plus are ideal for fast, reliable launches; WooCommerce and Magento suit deep customisation; headless commerce gives the best performance and bespoke UX. We recommend the right fit on a free call.

How much does an eCommerce website cost?

eCommerce projects start from \$6,000. A themed Shopify store costs less than a custom headless build or a multi-vendor marketplace with complex integrations. You receive a fixed-price proposal after we scope your requirements.

Can you migrate my existing store without losing sales or SEO?

Yes. We plan replatforming carefully — preserving URLs with 301 redirects, carrying over product data and SEO, and staging the launch — so you keep your rankings and avoid downtime during the switch.

Will the store be optimised for speed and mobile?

Always. We target a Largest Contentful Paint under 2.5 seconds with image optimisation and edge caching, and every store is mobile-first since most shopping traffic is on phones.

Do you help improve conversions after launch?

Yes. We offer an ongoing CRO retainer covering A/B testing, analytics, and iterative improvements to product pages, search, and checkout so your conversion rate keeps climbing.
