When off-the-shelf plugins fall short, or when you’re drowning in plugin conflicts, bloat, and features you’ll never use a custom WordPress plugin is the answer. At Rivmedia, we design and build bespoke WordPress plugins that are tailored precisely to your business processes, your tech stack, and your users.
As a UK-based WordPress agency with years of hands-on plugin development experience, we understand the platform inside out. We build to WordPress coding standards, follow security best practices, and write clean, maintainable code that won’t break when WordPress updates. Whether you need a simple admin tool, a complex API integration, or a fully featured WooCommerce extension, we can build it properly — from scratch.
Generic plugins are built for everyone, which means they’re rarely perfect for anyone. They carry unused code, introduce security vulnerabilities, and conflict with your theme or other plugins. A custom plugin does exactly what you need, and nothing more.
Nearly every, off the shelf plugin requires a pro version to get the functions that you need, the WordPress eco system has never been so expensive to run a website, which then generate problems during updates, custom made plugins don’t come with that many hurdles.
Every plugin we build is scoped around your exact workflows, users, and goals. No compromises, no workarounds, just functionality that fits.
We follow WordPress security best practices from the ground up, proper nonces, sanitisation, capability checks, and prepared queries as standard.
No bloat, no unused features. Custom code that loads fast, uses autoloading correctly, and won’t drag down your WordPress performance.
Written to WordPress standards so it stays compatible through core updates. We use OOP architecture and PSR-4 autoloading where appropriate.
All development is handled by our UK-based team. No outsourcing, no hand-offs. You deal directly with the people writing your code.
Everything we build is fully yours. No licensing fees, no lock-in. You receive the full source code and can deploy, modify, or hand it on as you see fit.
The range of custom WordPress plugins we build is broad. Here’s a flavour of what we regularly deliver for clients, but if your requirement isn’t listed, just ask. If it can be done in WordPress, we can build it.
Tell us what you’re trying to achieve and we’ll give you an honest assessment of what’s possible, how long it would take, and what it would cost. No obligation, no sales pitch.
Custom plugin development doesn’t happen in isolation — it works best as part of a wider WordPress strategy. At Rivmedia, we’re not just plugin developers; we’re a full-service WordPress agency that handles everything from design and hosting through to ongoing maintenance.
If you need a plugin integrating with WooCommerce, we have deep ecommerce experience. If you want your site to perform well in search, we understand SEO. And if you need the whole site looking after, our WordPress maintenance plans keep everything ticking over. Custom plugin development is one piece of a complete picture, and we can handle as much or as little of that picture as you need.
Custom plugin development is a great fit if you’re:
Pricing depends entirely on the complexity and scope of the plugin. A straightforward admin tool or small integration might start from around £500+vat, while a complex WooCommerce extension or API integration with significant business logic will cost more. We always provide a detailed quote after scoping your requirements, no surprises.
Simpler plugins can be delivered in a week or two. More complex projects with detailed integrations, admin interfaces, and testing cycles typically take 3–6 weeks. We’ll give you a realistic timeline as part of the scoping process and keep you updated throughout.
Yes, provided it’s maintained. We write to WordPress coding standards and avoid deprecated functions, which gives your plugin the best chance of remaining compatible through core updates. We also offer ongoing WordPress maintenance plans that include compatibility monitoring for any plugins we build.
Absolutely. Whether it’s a plugin you or another developer built, or a commercial plugin you’ve purchased, we can audit, extend, or modify it. We’ll always review the existing code first and let you know if a rebuild would be more practical than patching.
Yes, WooCommerce extensions are one of our specialisms. We’ve built custom checkout flows, shipping integrations, order management tools, product configurators, and more. See our ecommerce development page for more detail.
Security is built in from the start. Every plugin we write follows WordPress security best practices: nonce verification on all forms and AJAX requests, data sanitisation and validation on all inputs and outputs, capability and permission checks, and prepared queries for any database work. We don’t bolt security on as an afterthought.
Yes, 100%. You receive the full source code and all intellectual property rights. There are no ongoing licensing fees and no lock-in to us as a supplier. The code is yours to deploy, modify, or use however you wish.
Yes. We regularly build integrations with external systems, CRM platforms, shipping carriers, accounting packages, marketing tools, payment gateways, and more. If the third-party service provides an API, we can build the integration. We’ll review the API documentation as part of scoping and flag any limitations before we start.
