What We Build
Custom WordPress Development Services
From ground-up website builds to complex web application development, our WordPress specialists cover every layer of the stack.
Bespoke Theme Development
Your brand deserves more than a modified template. We build fully custom WordPress themes from your Figma or PSD files, pixel-perfect, lightning-fast, and uniquely yours.
Custom Plugin Development
When the plugin repository falls short, we build it from scratch. Our developers create secure, scalable WordPress plugins tightly integrated with your existing systems and third-party APIs.
Custom WooCommerce Development
Turn WordPress into a high-converting eCommerce engine. We build custom WooCommerce stores with tailored checkout flows, payment gateway integrations, and performance-tuned product catalogues.
Headless WordPress Architecture
Decouple your CMS from your frontend for unmatched performance. We architect headless WordPress solutions using React or Next.js, the editorial flexibility of WordPress with the speed of a modern frontend.
Performance Optimisation & Core Web Vitals
A slow site kills conversions and rankings. Our engineers audit and rebuild your WordPress site for Core Web Vitals compliance, achieving sub-2-second load times that Google rewards.
Migration & Rebuilds
Outgrown your current setup? We migrate complex WordPress sites, rebuild legacy codebases to modern standards, and transition Wix, Squarespace, or Webflow sites to a fully custom WordPress environment.
CASE STUDIES

Frequently Asked Questions
Everything you need to know before commissioning a custom WordPress build with Webermelon.
1. What makes custom WordPress development different from using a theme?
A custom build is architected specifically for your business: no bloated code from unused features, no design compromises, and no shared visual identity with thousands of other sites. The result is better performance, a stronger brand, and a codebase you fully own and control.
2. How long does a custom WordPress website take to build?
Project timelines depend on scope. A standard custom WordPress site typically takes 4 to 8 weeks from kickoff to launch. Complex builds, with custom plugins, eCommerce, or API integrations, are scoped individually. We always provide a detailed timeline before work begins.
3. Will I be able to manage the site myself after launch?
Absolutely. Every custom WordPress project we deliver includes a tailored CMS setup designed for non-technical editors. We also provide documentation and a handover session so your team can manage content confidently from day one.
4.Do you build custom WordPress plugins?
Yes, custom plugin development is one of our core services. Whether you need a bespoke booking system, a data integration layer, or a proprietary feature unique to your business, we design and build WordPress plugins that are secure, performant, and maintainable.
5. Can you rebuild or migrate an existing WordPress site?
Yes. We handle full CMS migrations and site rebuilds regularly, including moves from Wix, Webflow, Squarespace, or legacy WordPress installations. We preserve your SEO equity, maintain data integrity, and execute migrations with zero downtime.
6. Is your custom WordPress development white-label friendly?
Yes. We are a preferred white-label WordPress development partner for digital agencies worldwide. All deliverables, documentation, and communications are branded to your agency. Your clients never know we exist.
7. How do you ensure the site is optimised for SEO?
SEO is built into the foundation, not bolted on at the end. We use semantic HTML5, structured data (schema markup), clean URL architecture, Core Web Vitals optimisation, and proper heading hierarchies as standard on every custom WordPress build.
8. What does post-launch support include?
All custom WordPress projects include a dedicated support window post-launch covering bug fixes, performance monitoring, and minor amendments. We also offer ongoing retainer plans for teams that want continuous development and maintenance support.
