Built Because Off-the-Shelf Solutions Required Compromises
Every plugin in our portfolio started as a client requirement that no available plugin could meet correctly. The Technophobia SEO plugin because no available SEO plugin handled all schema types without conflicts. The Holiday Home Booking plugin because no booking plugin handled Cumbrian holiday let pricing complexity. The Learner Management System because no LMS handled funded training eligibility requirements.
We build plugins when the compromise of using a generic solution would produce a worse outcome than a purpose-built one. That means we scope carefully before recommending a custom build — if an available plugin genuinely fits your requirements, we tell you. If it does not, we build the solution that does.
Our WordPress development services cover everything from custom theme builds to complex REST API integrations — all delivered by Technophobia Ltd, the software arm of the Whamos group.
Plugin development is one part of what we do — see our Web Design Cumbria hub for the broader service list.
Types of Custom Plugins We Build
Six categories of custom plugin development — all deployed on live client sites across Cumbria and the North West.
How We Build Custom Plugins — Specification, Standards, Ownership
Every custom plugin project starts with a discovery conversation where we understand your requirements in detail. Then we produce a written specification covering every feature, every data structure, every integration, and every user interaction. The specification is the contract — the price is fixed against it before development begins.
WordPress coding standards throughout. Correct use of hooks, filters, and the Settings API. No direct database queries bypassing the WordPress abstraction layer. No shortcut code that breaks on WordPress updates. Code that any competent WordPress developer can read, understand, and maintain without us — because creating dependency on our continued involvement is not in your interests.
Your custom-built work is yours on delivery. The plugin code, the database tables, the documentation, and the right to modify and distribute the plugin. No additional charges for the original custom work. Any third-party plugin licences are outlined separately. If you want another developer to extend it in five years, you have everything they need.
We test thoroughly before delivery. Unit testing, integration testing, and real-world testing on a staging environment before anything goes to production. We do not consider a plugin finished until it works correctly under real conditions — not just in our development environment.
Documentation is part of the delivery. Not an afterthought — every custom plugin comes with developer documentation covering the code architecture, database structure, hook and filter reference, and any required configuration. Written so that any developer can work with it, not just the one who built it.
