Why custom
When off-the-shelf won’t do.
The plugin directory is vast, but sometimes the thing you need simply doesn’t exist, or the closest match is bloated, abandoned or fights with the rest of your site.
We build lean, purpose-made plugins that do exactly one job well: fast, secure, well-documented and easy to maintain. No feature bloat, no licence fees, no surprises.
- Exactly the functionality you need
- No third-party licence fees
- Yours to own, outright
The process
How we build your plugin.
A clear, collaborative path from idea to a reliable, maintainable plugin.
01
Scope & specify
We dig into exactly what you need it to do, the edge cases, and how it fits your existing site, then write a clear spec.
02
Architect
We design the plugin properly, using WordPress hooks and standards so it’s robust, secure and update-safe.
03
Build & review
We develop it in clean, documented code, sharing builds as we go so you can see it taking shape.
04
Test thoroughly
We test against real-world scenarios and your other plugins to make sure it behaves, every time.
05
Ship & support
We deploy it live, hand over documentation, and stay on hand to maintain and extend it as you grow.
What we build
From small tweaks to serious functionality.
If it can be done in WordPress, we can probably build it. A few of the things we’re regularly asked for.
WooCommerce extensions
Bespoke shipping, pricing, product or checkout logic tailored to how your store actually works.
Custom admin tools
Dashboards, reports and back-office tools that make running your site genuinely easier.
Custom content types
Bespoke post types, fields and taxonomies that model your data exactly how you need it.
Automation hooks
Trigger emails, syncs or actions automatically when something happens on your site.
Fixing & extending
Inherited a buggy or limited plugin? We can repair, extend or replace it cleanly.

We commissioned Josh to renew our website and he has done a great job for us. We are all working as volunteers and he did not put us under any pressure to respond quickly. But he always replied quickly and made changes very efficiently. It was a pleasure to work with him.

Super work. Prystine brought a business-value added dimension to their tech advice and implementation for our start-up. As a management consultant myself, I valued Prystine's ability to work seamlessly to offer integrated solutions tailored to the client. Working with Prystine has been invaluable to us operationally. We will retain their services for our venture, as we continue to scale the business.

I don’t think I can put into words and express how over the moon and happy I am with the website Prystine have developed for my business! They took time to understand what I wanted and worked with me testing ideas, tweaking and changing until I was happy with it. Josh was so friendly, encouraging, patient and understanding as I took time to really think about what I wanted from my website. He wasn’t pushy and worked with my pace and timescales. The support has been amazing and the responsiveness has been epic. Highly recommend Prystine - thank you for helping make my dream come alive!

Josh provided a very professional service. Always friendly and nothing was ever too much trouble. He had some great, creative ideas for my website and patiently guided me through how to make basic changes to the site but stressed that he was always on hand if I needed help. Really recommend a chat with Josh if you are looking to build/refresh your website.

I have recommended my clients to Prystine when they wanted to up their online presence. The fact they have thanked me for putting them in touch with Josh is high praise indeed. You will not find better value for money and professionalism.

Josh is so calm and laid back, yet detailed and professional at the same time. The migration from my old server was seamless and every thing was clearly explained. I'm delighted to have moved to a business with the personal touch, I have so much more confidence in my hosting now.
James Butlervia Google Our pricing
How much does a custom plugin cost?
Every plugin is different, so we scope and quote each one precisely. As a rough guide, most plugin projects sit in this range.
Typical plugin project
£900 to£8k
Simple, single-purpose plugins sit at the lower end; complex integrations and WooCommerce extensions toward the top. We’ll give you a clear, fixed quote once we understand the scope.
You own the code, fully documented
Once paid, the plugin and all its code are yours outright, with documentation so any developer can maintain it. No lock-in, no licence fees. Prices exclude VAT.
How long does a custom plugin take?
Simple plugins can be a week or two; larger integrations a few weeks to a couple of months. We’ll give you a realistic timeline alongside the quote.
Will it survive WordPress updates?
Yes. We build using official WordPress hooks and standards rather than hacks, so plugins stay compatible through updates. We can also keep them maintained on a care plan.
Do I own the plugin?
Completely. Once it’s paid for, the code and all intellectual property are yours, with documentation included. There are no ongoing licence fees.
Can you fix or extend an existing plugin?
Often, yes. We can repair bugs, add features or tidy up an inherited plugin. Sometimes a clean rebuild is the better value option; we’ll tell you honestly which makes sense.
