Custom web application development: Laravel and PHP systems you own outright
Booking engines, client portals, dashboards and workflow automation. Built with Laravel 12, PHP 8.2 and MySQL 8. Not no-code glue, not off-the-shelf compromises. You own the code, the data and the server.
Fixed quote within 48 hours. No obligation, no pushy follow-ups.
What we build
Six types of custom web application, each replacing a spreadsheet, an email chain, or software that never quite fit.
Dashboards
Real-time data visualisation, KPI tracking, and reporting dashboards that consolidate your business numbers into one screen.
Client portals
Secure login areas where your clients can view documents, track progress, upload files, and manage their account.
Booking systems
Custom scheduling, availability calendars, and payment-integrated booking, built around your workflow, not someone else's.
Automation
Repetitive tasks, data entry, report generation, automated. Free up your team for work that actually needs a human.
Integrations
Connect your app to Xero, Stripe, CRMs, email platforms, or any API. If it has an endpoint, we can talk to it.
Legacy replacements
That creaky old system everyone hates? We'll rebuild it properly: faster, cleaner, and actually usable.
How we choose the right stack
We don't force a framework on every problem. The job decides the stack — and if all you need is a brochure site, that's a different thing. See web development.
Custom PHP applications
PHP 8.2 · PDO · PHPMailerFor applications that need a database but not a framework. Direct prepared queries, zero ORM overhead, exactly the code required. When the job is a booking system with one user role and a handful of tables, a framework is overhead.
Used for: D.E.S.T Football Coaching. 427 bookings, 135+ parent accounts
Laravel applications
Laravel 12 · MySQL 8 · ViteFor complex systems where the framework earns its place. Multiple user roles, payment processing, background jobs, queues, caching, structured testing. The scaffolding that separates a pile of code from a maintainable system.
Used for: Cloud Nine Play Café. Stripe booking engine, 0 payment state errors
Verified production systems, not mockups
Two live applications running real money and real customers right now.
Cloud Nine Play Café: Booking engine
Three booking types. Stripe payments. Real-time availability. Replaced spreadsheets and double-bookings with a system that loads in a second and hasn't had a single payment state error since launch.

427 bookings. 135+ parent accounts. 291 automated emails. No framework overhead, just the code the job needed, and a grassroots club that went from drowning in spreadsheets to running itself.

Own it, don't rent it
A SaaS platform at £150/month is £5,400 over three years, and you walk away with nothing when the payments stop. A £5,000 custom build is a one-off cost, £15/month hosting via Unity Tech, and 100% source code ownership from day one. Pay once. Host anywhere. Keep everything.
Because we're not VAT-registered, non-VAT-registered SMEs and charities save 20% against VAT-registered agencies. Registered UK charities get a further 20% off every build under Penguins with Purpose.
API-first integrations
If it has an endpoint, we can talk to it. Legacy systems without APIs? We build the bridge.
Xero
Invoices, bills and ledger sync straight from your web app. No double entry.
Stripe
Card payments, subscriptions and webhooks handled properly, with payment state you can trust.
HubSpot & CRMs
Push leads, contacts and deals between your app and your CRM automatically.
Sage
Accounting integration for UK businesses already running on Sage.
Email & messaging
Transactional email, notifications and follow-ups, automated and on schedule.
Legacy SQL sync
No API? We build scheduled syncs straight to the database. Old system keeps working while the new one takes over.
Security, accessibility and hosting: built in
Security
Prepared PDO statements against SQL injection, CSRF and XSS protection, encrypted auth and role-based access. No plugin surface to attack.
Accessibility
WCAG 2.2 AA compliance. Keyboard navigation, screen-reader labels, proper contrast and focus states, built into every component, not bolted on after.
Hosting
Unity Tech UK NVMe infrastructure. £15/month, air-gapped backups, automatic failover, and 24/7 monitoring. The account is in your name.
Direct to the developer, start to finish
No account manager, no telephone game. You brief Rob, Rob builds it, you review each stage.
Virtual Cuppa
A relaxed 20-minute call. You explain the problem, we tell you straight if a custom app is the right fix.
Proper Plan
Scope, architecture, timeline and fixed price in writing. Agreed before a line of code is written.
Build
We build in stages. You review each milestone in a real environment. No black boxes, no surprises.
Test
Two quality gates, technical and design, before you ever see it. Responsive, accessible, fast.
Launch
When you're happy, it goes live. 30 days post-launch support included, free.
Beyond
No retainer, no lock-in. We're here for hosting, maintenance and future development, but you own everything.
Common questions
How is this different from using WordPress? ▾
WordPress is a content management system with plugins bolted on. A web application is purpose-built software that does exactly what your business needs without the bloat and security surface of a CMS. A booking system, client portal or dashboard will be faster, more secure and easier to scale than anything you can piece together with plugins.
How much does a custom web application cost? ▾
Focused, single-purpose applications start from £5,000, delivered in 4 to 8 weeks. Multi-role platforms with third-party API integrations are scoped on a fixed-price quote and take 8 to 16 weeks. Because we're not VAT-registered, clients pay 0% VAT overhead and own 100% of the source code on delivery.
Can you integrate with my existing systems? ▾
Almost certainly. We build API-first, so your app can talk to Xero, Stripe, HubSpot, Sage, email platforms and any third-party service. For legacy systems without a modern API, we connect via secure direct database access or scheduled automated syncs.
How long does a web application take to build? ▾
Small applications (booking systems, simple dashboards) typically take 4 to 8 weeks. Larger applications with complex logic or integrations take 8 to 16 weeks. We give you a fixed timeline with milestones before we start. No surprises, no feature creep.
Do you build mobile apps? ▾
We build Progressive Web Apps (PWAs) rather than native iOS or Android apps. A PWA installs to the home screen, works offline, and avoids the 15 to 30% app store commission and the cost of maintaining two codebases. One system, everywhere, owned by you.
