We build high-performance storefronts that convert. From headless Shopify implementations to custom marketplace platforms, we obsess over page speed, personalisation, and checkout optimisation.
A complete, opinionated stack of capabilities — from architecture to launch — without the agency overhead.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
