Ecommerce Development Agency — Custom Storefronts

Shopify is the right choice if you want to launch quickly, prefer managed infrastructure, and are comfortable with its ecosystem. A custom storefront (headless or fully custom) makes sense when you need unique UX, complex business logic, or deep integration with existing systems. Kultrix builds both.

Headless ecommerce decouples the storefront (frontend) from the commerce engine (backend). You get Shopify's battle-tested cart and checkout under the hood, but a fully custom Next.js frontend with complete design freedom and superior performance.

We integrate Stripe for custom storefronts — it handles card processing, 3D Secure authentication, Apple Pay, Google Pay, and PCI compliance. For Shopify stores we use Shopify Payments plus additional gateways as needed.

We implement structured data (Product, BreadcrumbList, Review schemas), generate XML sitemaps, configure canonical URLs for faceted navigation, optimize product image alt text, and build server-rendered pages for fast Googlebot crawl speeds.

Yes. Kultrix handles platform migrations — WooCommerce to Shopify, Magento to headless, or any custom store to a modern stack. We migrate products, customers, order history, and SEO metadata with zero data loss.

We build inventory systems that track stock per SKU, support multiple variant dimensions (size, color, material), trigger reorder alerts at configurable thresholds, and sync with third-party inventory management systems via webhooks or API.

Yes. B2B ecommerce has unique requirements — company accounts, net payment terms, quote requests, tiered pricing, and purchase order workflows. Kultrix has built B2B platforms with all of these features on both custom and Shopify Plus stacks.

We apply CRO best practices throughout: fast page load (under 2s), sticky add-to-cart on mobile, exit-intent offers, streamlined checkout with minimal fields, trust signals near CTAs, and abandoned cart email sequences. We track improvement with A/B testing.

We integrate with shipping carriers (UPS, FedEx, USPS) for real-time rate calculation, implement TaxJar or Avalara for automated sales tax compliance, and build fulfillment workflows that trigger on order creation.

Yes. We can add ecommerce functionality to an existing Next.js, WordPress, or custom site — product pages, cart, checkout, and payment — without rebuilding your entire site. We scope the integration carefully to minimize disruption.

Absolutely. Mobile accounts for 60–70% of ecommerce traffic. We design and build checkout flows optimized for mobile — large tap targets, autofill support, Apple Pay / Google Pay for one-tap checkout, and minimal form fields.

A custom storefront MVP takes 8–12 weeks. A full-featured ecommerce platform with inventory, admin, and integrations takes 3–5 months. Kultrix stages delivery so you can launch with core features and add complexity post-launch.
