eCommerce Website Development Built to Sell. Built to Scale.
Most online stores look the part but leak revenue at every step – slow load times, broken checkout flows, and templates that make you look identical to your competitors. We build custom eCommerce websites engineered around conversion, performance, and the experience your customers actually expect.

I’ve been working already many times with Webermelon on different web projects. Fully customized PDF generating application, WordPress websites and customization. The work was always professional and very satisfying and on time. Looking forward to work on new projects again. Thanks!
What We Build
eCommerce Development Services That Cover Every Platform and Use Case
From WooCommerce and Shopify builds to fully headless storefronts – our eCommerce website development team has built stores at every scale and for every vertical.
Custom WooCommerce Development
Bespoke WooCommerce stores built on WordPress – custom themes from your Figma files, tailored product structures, complex variable pricing, and the flexibility to extend the platform to match your exact catalogue and checkout requirements.
Shopify & Shopify Plus Development
Custom Shopify theme development, Liquid templating, app integrations, and Shopify Plus scripts for enterprise-grade discount logic, checkout customisation, and B2B pricing – built by developers who know the platform properly.
Headless eCommerce Development
Next.js or React frontends powered by WooCommerce, Shopify, or a composable commerce backend – giving you lightning-fast page speeds, total design freedom, and the performance edge that directly impacts conversion rates.
Payment Gateway Integration
Seamless integration of every major payment gateway – Stripe, PayPal, Klarna, Mollie, and regional providers – with custom checkout flows, buy-now-pay-later options, and multi-currency support built to reduce abandoned carts at the final step.
Performance & Conversion Optimisation
We audit and rebuild slow eCommerce sites for Core Web Vitals, mobile performance, and checkout funnel friction – because a one-second improvement in load time is directly measurable in revenue, not just a vanity metric.
ERP, CRM & Third-Party Integrations
We connect your eCommerce store to your wider business stack – inventory management, accounting software, CRM systems, fulfilment providers, and marketing platforms – so orders, stock, and customer data flow without manual intervention.

Why Webermelon
An eCommerce Development Partner That Understands Revenue, Not Just Code
Conversion-First Development
Every decision – from page structure and image loading strategy to checkout flow and mobile layout – is made with conversion rate in mind. We don't build pretty stores that don't sell. We build stores that perform.
Platform Expertise, Not Platform Bias
We don't push one platform because it suits us. We recommend WooCommerce, Shopify, or a headless approach based on your catalogue complexity, growth plans, and operational requirements – and we're experts in all three.
White-Label Ready for Agencies
Deliver eCommerce builds under your agency brand without expanding your in-house team. We work entirely behind the scenes – all code, documentation, and communication delivered in your name with full NDA coverage.
Post-Launch Support Included
An eCommerce store is a living product. We offer ongoing maintenance, performance monitoring, seasonal update support, and continuous feature development – so your store keeps improving after day one.
Transparent Delivery, Zero Surprises
Scope agreed upfront. Clear milestones. Regular demos of working software. You know exactly what's been built, what's coming next, and what it costs – with no change order surprises or scope disputes mid-project.
How It Works

Frequently Asked Questions
Common questions from brands and agencies before starting their eCommerce website development project with Webermelon.
1. WooCommerce or Shopify – which platform do you recommend?
It depends entirely on your business. WooCommerce gives you more flexibility and total ownership – ideal for complex catalogues, custom pricing rules, and content-heavy stores. Shopify excels for fast-moving DTC brands that prioritise simplicity and speed of deployment. We recommend the right platform after understanding your specific requirements, not the one that suits us.
2. What is headless eCommerce and do I need it?
Headless eCommerce separates your storefront (what customers see) from your commerce backend (products, orders, inventory). The result is dramatically faster page speeds and total design freedom. Most growing brands benefit from it, but it adds complexity and cost – we’ll advise honestly on whether it’s right for your stage and budget.
3. Can you migrate our existing store to a new platform?
Yes. We handle full eCommerce migrations – products, variants, customer data, order history, SEO redirects, and URL structures. We plan migrations carefully to protect your search rankings and ensure zero downtime on the day of cutover.
4. Do you offer white-label eCommerce development?
Yes, this is a core part of our offering. Agencies use us to deliver eCommerce builds entirely under their own brand. All deliverables, code, and communication are in your name. We sign NDAs before any project begins and never disclose our involvement to your clients.
5. How long does an eCommerce website build take?
A focused WooCommerce or Shopify build typically takes 6 to 10 weeks depending on catalogue size, design complexity, and integration requirements. A headless eCommerce build runs closer to 10 to 16 weeks. We confirm the timeline precisely during the scoping session before any work begins
6. Can you improve the performance of our existing store?
Yes. We run full performance audits covering Core Web Vitals, server response times, image delivery, JavaScript bloat, and checkout friction. We then implement targeted fixes and report on the before-and-after impact on both speed scores and conversion metrics.
7. Do you integrate with fulfilment and inventory systems?
Yes. We connect eCommerce stores to fulfilment providers, warehouse management systems, inventory platforms, and accounting software – so stock levels, order status, and financial data sync automatically without manual reconciliation.
8. What ongoing support do you offer after launch?
We offer monthly retainer support covering performance monitoring, security updates, plugin and platform version management, feature additions, and campaign-specific development. Many clients stay with us as their long-term eCommerce development partner well beyond the initial build.
