Testimonials

What Our Clients Say

What impressed us most was how Kultrix handled the full stack - frontend, backend, and mobile - with one cohesive team. Communication was clear, delivery was predictable, and the final product exceeded what we initially scoped.

Frank W.

Co-CEO

Kultrix built both our web platform and mobile app from scratch. Their team understood the complexity of our industrial workflows and translated them into clean, intuitive interfaces. We launched on time and our operators adopted the tools immediately.

Dinant V.

Co-CEO

Kultrix handled everything for us - landing page, dashboard, mobile app, and even a Chrome extension. Having one team own the entire product surface meant everything felt connected and consistent. They shipped fast and the quality speaks for itself.

Timur G.

CEO, Ping Proxies

Kultrix has been our go-to partner for multiple projects - from marketing websites to full mobile applications and backend systems. They scale up when we need speed and maintain consistency across every project. Reliable, fast, and technically strong.

Musa S.

CEO, Volume Apps

Working with Kultrix on our mobile app and backend was seamless. They brought strong product thinking to every sprint, not just code. When priorities shifted, they adapted quickly without losing momentum. Exactly the kind of partner a product team needs.

Taj S.

Product Lead, Pelago

We needed a team that could handle mobile development, server infrastructure, and AI features all at once. Kultrix delivered on all three fronts. Our fitness platform went from concept to production in under four months with zero compromises on quality.

FAQ

Frequently Asked Questions

Premium Shopify themes are designed to serve thousands of different store types - they ship with code for features you will never use and inevitably constrain your brand expression. A custom theme is built precisely for your products, your customer journey, and your conversion goals. It loads faster, reflects your brand more accurately, and is far easier to maintain and extend as your business grows.

Standard placement is 48 hours from contract signing. Shopify is a well-staffed area of our team. For Shopify Plus specialists with checkout extension experience or Hydrogen/Storefront API headless development, 48 to 72 hours is typical.

A Shopify theme controls everything customers see - layout, product display, cart, checkout. A Shopify app adds functionality that the platform does not natively provide - custom pricing rules, workflow automations, integrations with external systems, or extended admin interfaces. Our developers build both, and understand when to use a theme customisation versus a lightweight app versus a full embedded application.

Yes. Shopify Plus unlocks capabilities unavailable on standard plans - checkout customisation with checkout.liquid and checkout extensions, Shopify Flow for automation, B2B wholesale features, custom storefronts via the Storefront API, and multi-store management. Our developers are experienced with Plus-tier features and understand the boundaries between standard customisation and what requires the Plus plan.

Checkout customisation on Shopify Plus follows two paths: checkout extensions (the recommended modern approach) for adding custom UI to the checkout UI Extension points, and checkout.liquid for more substantial layout changes (where available). Our developers work with both, use the Checkout Branding API for styling, and implement post-purchase pages and thank-you page extensions for upsells and surveys.

Yes. We build both public and custom (private) Shopify apps. Custom apps are scoped to your specific store - automating fulfilment workflows, syncing inventory with your ERP, providing custom admin pages for your operations team, or extending the storefront with functionality the Shopify App Store does not address. We use Remix with Shopify CLI for modern app development.

Shopify webhook processing is the foundation - we register webhooks for orders, inventory, and product events, build idempotent handlers that process them reliably, and queue downstream operations for external API calls. For bidirectional sync with ERPs or WMS systems, we implement polling or event-driven pipelines with conflict resolution and error alerting.

Yes. Shopify performance audits are a common engagement. We analyse theme JavaScript bundles, identify scripts blocking the critical render path, lazy-load non-essential functionality, optimise image delivery, remove unused app scripts that remain after uninstalling apps, and implement critical CSS inlining. These changes typically improve LCP by 30-50% and measurably reduce bounce rate.

Headless Shopify uses the Storefront API or Hydrogen framework to decouple the frontend from Shopify's native theme system. This provides maximum design flexibility and performance, but adds significant development complexity and cost. We recommend headless only when the native theme system genuinely cannot support your requirements - not as a default choice. Most stores achieve excellent results with well-built Online Store 2.0 themes.

Shopify has specific SEO constraints - canonical URL structure, pagination handling, duplicate content from collections, and limited control over certain meta tags. Our developers implement structured data (Product, BreadcrumbList schemas), optimise meta title and description templates, handle canonical tags correctly, ensure proper hreflang for international stores, and work within Shopify's sitemap generation rather than fighting it.

The minimum engagement is one month. Shopify projects range from focused theme customisation sprints (two to four weeks) to ongoing platform development partnerships. Many e-commerce businesses benefit from a standing development retainer to handle continuous optimisation and new feature requests.

Fixed-price engagements are available for clearly scoped deliverables - a custom theme, a specific app feature, an integration build. Monthly retainer and time-and-materials models suit ongoing platform development. All models include a dedicated account manager and full transparency on work completed.
