Web Application Development
Custom PHP & MySQL Web Applications
Beyond brochure sites — database-driven applications that automate your business, manage your data, and scale with you. Built in PHP and MySQL by a hands-on developer with 25+ years of experience.
Why Custom
When off-the-shelf software stops working for you.
Every growing business hits the same wall: the generic SaaS tool does 80% of what you need — and fights you on the other 20%. You end up bending your business to fit the software, paying per-user fees that scale the wrong way, and exporting spreadsheets to fill the gaps.
A custom web application flips that around. It does exactly what your business does, exactly how you do it. No feature bloat, no monthly per-user tax, no waiting for a vendor roadmap that never arrives. Just software that works the way you think.

Real Example — Miri-ad.co.uk
Miri-ad is a custom driver agency platform we built — hauliers can search, filter and book qualified drivers based on their exact requirements. PHP back end, MySQL driver database, custom booking engine.
Real Example — DeltaPerformance.co.uk
Custom vehicle lookup system with instant quote generation. Customers enter a registration plate, the system queries the DVLA API, matches it to services and generates a personalised quote automatically — all before the phone rings.
What We Build
Bespoke Systems, Built Around You
Some of the most common types of custom PHP application we build for UK businesses. If your system is not listed — ask. If it can be built in PHP and MySQL, we have probably built something like it.
Custom Admin Dashboards
Bespoke control panels that let you manage your business data the way you actually work — not the way some SaaS vendor decided.
CRM Systems
Customer relationship management tailored to your sales process, your pipeline, your data — no Salesforce tax, no per-user fees.
Booking Platforms
Appointment systems, class scheduling, service booking, resource management — with automatic confirmations, reminders and rescheduling.
Inventory Management
Stock tracking, order management, supplier integration, barcode scanning, low-stock alerts. Know what you have, where it is, and what is selling.
API Integrations
Stripe, GoCardless, PayPal, DVLA, Companies House, Royal Mail, Xero, Mailchimp, Twilio — we connect your system to the services that power your business.
Member Portals
Secure client or member areas with authentication, role-based access, document sharing, account self-service and subscription billing.
Database Architecture
Properly normalised MySQL schema design. Relational integrity, indexed queries, backup strategy — the foundation everything else sits on.
Process Automation
Automate the repetitive admin work that eats your week — invoices, reports, reminders, data sync. Software that does the boring stuff so you do not have to.
Secure Authentication
Modern password hashing, two-factor authentication, session security, CSRF protection. Built to protect your data and your customers.
Why Steony
Built Properly, Built To Last
Plenty of developers can slap a PHP script together. Fewer can architect a system that will still be maintainable and performant in five years.
Clean, Maintainable Code
Modern PHP (8.x), proper separation of concerns, documented. Any competent PHP developer can pick it up and continue — no obscure frameworks, no spaghetti.
You Own The Source Code
The source, the database schema, the documentation — all yours. No vendor lock-in, no "you cannot leave" clauses, no platform dependency.
Built To Scale
Properly indexed databases, efficient queries, sensible caching. Your system will still be quick when you have 10x the users you have today.
Integrates With Anything
If it has a REST API, we can connect to it. Payments, shipping, accounting, SMS, email, government data — your system plays nicely with the tools you already use.
Direct Access To The Developer
No account managers, no offshore team. Talk directly to the person writing your code. Questions get real answers, fast.
Ongoing Support Available
Every custom system can be paired with a support retainer — so when something breaks at 9pm on a Tuesday, there is someone to call who already knows your system.
Our Process
From Idea to Working Software
Custom application development is not a sprint — it is a considered conversation. Here is how we take a rough idea and turn it into a working system your business runs on.
Discovery
A proper conversation about your business, your process, and the problem you are trying to solve. No technical jargon required.
Architecture
We design the data model, the screens, and the workflows — and show you before a single line of code is written.
Build & Review
We build in iterations, showing you working software as we go. You test, give feedback, and we refine — no big-bang reveal at the end.
Launch & Support
We deploy, train your team, and provide documentation. Ongoing support means someone is always on call when you need a tweak.
