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 stores to fully headless storefronts, our eCommerce website development team builds online stores around your catalogue, business operations and growth plans.

Custom WooCommerce Development

We build custom WooCommerce stores on WordPress with tailored themes, product structures and checkout functionality. From variable products and custom pricing to inventory management, we adapt the platform to your catalogue and business requirements.

Shopify & Shopify Plus Development

We develop Shopify and Shopify Plus stores with custom themes, Liquid development and app integrations. Our team can configure advanced discount rules, checkout features and B2B pricing to support growing online businesses.

Headless eCommerce Development

We build headless eCommerce storefronts using Next.js or React with WooCommerce, Shopify or composable commerce backends. This approach gives your team greater design flexibility, faster storefront performance and more control over the customer experience.

Payment Gateway Integration

We integrate payment gateways such as Stripe, PayPal, Klarna, Mollie and regional payment providers. Our custom checkout solutions support secure transactions, multiple currencies and flexible payment options to make purchasing easier for customers.

Performance & Conversion Optimisation

We improve existing eCommerce websites by addressing Core Web Vitals, slow page loading, mobile usability and checkout issues. Our optimisation work focuses on reducing friction throughout the shopping journey and helping customers complete their purchases.

ERP, CRM & Third-Party Integrations

We connect your eCommerce store with ERP, CRM, inventory, accounting, fulfilment and marketing systems. These integrations help synchronise orders, stock levels and customer information, reducing manual work across your business operations.

Why Webermelon

An eCommerce Development Partner That Understands Revenue, Not Just Code

Conversion-First Development

Every decision, from page structure and image loading to product navigation and checkout flow, considers the customer journey. We build online stores that make it easier for visitors to find products, complete purchases and return.

Platform Expertise, Not Platform Bias

We do not recommend a platform simply because it is familiar. We assess your catalogue, business model, integrations and growth plans before recommending WooCommerce, Shopify or a headless eCommerce solution.

White-Label Ready for Agencies

Deliver eCommerce projects under your agency brand without expanding your in-house development team. We work behind the scenes, providing code, documentation and project communication under your name with agreed NDA and confidentiality arrangements.

Post-Launch Support Included

An online store needs ongoing attention after launch. We support maintenance, platform updates, performance monitoring, seasonal changes and feature development to help your store remain reliable as your business grows.

Transparent Delivery, Zero Surprises

We agree on the project scope, milestones and delivery expectations before development begins. You receive regular updates and demonstrations of working features, so you know what has been completed, what comes next and how the project is progressing.

How It Works

Your eCommerce Store Live in 4 Clear Phases

Our eCommerce development process takes your project from the first brief to launch through four clear phases. We keep the scope organised, communicate progress and review key milestones to support a smooth delivery.

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 on your business requirements. WooCommerce offers greater flexibility and control over custom features, product structures and content. Shopify is suitable for businesses that want a managed platform with simpler store administration. We assess your catalogue, integrations and growth plans before recommending the right option.

2. What is headless eCommerce and do I need it?

Headless eCommerce separates the customer-facing storefront from the backend that manages products, orders and inventory. It offers more design flexibility and can improve storefront performance. However, it also adds development complexity and cost. We recommend it when your business needs justify that investment.

3. Can you migrate our existing store to a new platform?

Yes. We handle eCommerce migrations, including products, product variations, customer data, order history and URL structures. We also plan redirects and technical checks to protect your existing search visibility and reduce disruption during the platform change.

4. Do you offer white-label eCommerce development?

Yes. We work with agencies that need a reliable development partner for client projects. Our team delivers eCommerce websites under your agency brand, with agreed communication, documentation and confidentiality arrangements. We do not approach or disclose our involvement to your clients.

5. How long does an eCommerce website build take?

A focused WooCommerce or Shopify store typically takes 6 to 10 weeks, depending on catalogue size, design requirements and integrations. A headless eCommerce project may take 10 to 16 weeks. We confirm the expected timeline after reviewing your project scope.

6. Can you improve the performance of our existing store?

Yes. We audit Core Web Vitals, server response times, image delivery, JavaScript loading and checkout usability. Based on the findings, we implement improvements to reduce loading delays and remove friction from the shopping experience.

7. Do you integrate with fulfilment and inventory systems?

Yes. We connect eCommerce stores with fulfilment providers, warehouse management systems, inventory platforms and accounting software. These integrations help keep stock levels, order statuses and business records synchronised without relying on manual updates.

8. What ongoing support do you offer after launch?

We provide ongoing support through maintenance and development retainers. This can include performance monitoring, security updates, platform and plugin updates, bug fixes, new features and seasonal campaign support. The support plan depends on your store’s requirements.
