Custom PHP and MySQL application development in Lisburn
When an off-the-shelf plugin does not fit the business, I build the thing that does — booking systems, client portals, quote calculators, admin dashboards, and integrations with whatever API you already depend on. For Lisburn businesses, quoted in GBP from $200, typically live in 10 days.
What custom php and mysql application development includes for a Lisburn business
Fixed scope, agreed in writing before development starts. From $200, typically live in 10 days.
- Database design and schema, documented rather than improvised
- Application build in PHP with a MySQL backend
- Admin interface built for the people who will use it daily
- Role-based access control where more than one person logs in
- Third-party REST API integrations
- Transactional email via PHPMailer with proper SPF/DKIM alignment
- Input validation, prepared statements and CSRF protection throughout
- Written handover documentation — you are not dependent on me to keep it running
The terms for a British client
| Starting price | From $200, quoted and invoiced in GBP |
|---|---|
| Typical timeline | 10 days once content is supplied |
| Tax position | VAT at 20% once you are registered — my invoices are outside the scope of UK VAT and you account for them under the reverse charge |
| Data protection | UK GDPR and the Data Protection Act 2018 — resolved by a pre-signed DPA with a completed UK International Data Transfer Addendum |
| Payment rails available | Stripe, GoCardless for Direct Debit, and Klarna or Clearpay where basket sizes justify it |
| My day in Lisburn time | 05:00–14:00 — about 5 hours of overlap |
Why this matters for United Kingdom specifically
UK local search is the most saturated in the English-speaking world, so a merely competent site does not win the job — the quote form does. Every UK build I ship is specified around the enquiry step first and the homepage second.
Why the Lisburn quote lists exclusions as well as inclusions
Every quote I send names what is not included as explicitly as what is. Copywriting from scratch, photography, logo design, ongoing content, paid advertising and third-party licence fees are the usual ones. A quote listing only inclusions is not cheaper — it is the same price with the arguments deferred to later.
This is unpopular at the proposal stage and it is the reason fixed prices hold. Someone comparing three quotes for a Lisburn project is usually comparing three different scopes without realising it, and the cheapest one is very often the one that excluded the most while saying the least.
Property, lettings and estate agencies in Lisburn
Property sites live or die on search and filtering. A listing grid that cannot be filtered by the three things buyers actually care about — price, bedrooms, area — sends people to the portals, and once they are on a portal you are competing on fee with every other agency in Lisburn.
The technical half is feed handling: listings usually arrive from a CRM in a format designed two decades ago, and keeping the site, the portals and the window cards in agreement is where the real work sits. It is worth doing properly, because a property still showing as available after it is let generates the angriest phone calls in the business.
Analytics that has never once been looked at
Most sites carry a tracking tag and no measurement. Nobody defined what counts as a conversion, so the dashboard reports sessions and bounce rate — numbers that move up and down and change no decision anybody makes.
Useful measurement is narrow: form submissions, phone taps, WhatsApp clicks, and which pages preceded them. Four numbers checked monthly beat forty never opened, and knowing which Lisburn search terms actually produce enquiries is what turns the site from a cost into something you can steer.
What I am not claiming about Lisburn
- I have no office, postal address or phone number in Lisburn
- I cannot meet you in person, and if that is a requirement you should hire locally
- I am not claiming existing clients in Lisburn specifically — my live work is listed on the work page and you can check it
- Nothing on this page is a guarantee of search rankings, which no developer can honestly offer
Custom PHP and MySQL application development in Lisburn — common questions
- What hours will you be available to us in Lisburn?
- My standard day lands at 05:00–14:00 your time — about 5 hours of genuine overlap with a normal Lisburn working day. That is enough for one reliable daily window rather than constant back-and-forth, so Lisburn projects run on written updates plus one scheduled call a week.
- Can you fix my existing site rather than rebuild it?
- Often, yes, and it is usually the cheaper answer. Speed problems, a broken mobile layout, a form that silently fails or missing structured data are all fixable on the site you already have. I will tell you which of the two you need after looking, and a rebuild only gets recommended when the fix would cost more than starting again.
- What payment methods can my Lisburn checkout accept?
- For United Kingdom: Stripe, GoCardless for Direct Debit, and Klarna or Clearpay where basket sizes justify it. The right combination depends on your average basket and your customers, and picking wrong is expensive — the payment method a buyer expects but cannot find is one of the most common reasons a checkout is abandoned at the final step.
- How long does a Lisburn project actually take?
- Three days for a business site, seven for a store, ten for a custom application. That holds because the process is fixed rather than improvised and because your content exists on day one. What stretches a build is almost never the code — it is waiting for copy, logos and photographs, so those are requested before the clock starts.
- What happens if I am not happy with the result?
- Work is delivered in milestones against a written scope, and you review each one on a staging URL before it is paid for. If the delivered milestone does not match the scope, it gets corrected before anything moves forward. That structure exists so disagreement is resolved at the stage it happens rather than at the end when it is expensive.
- Do you build on WordPress or something custom?
- Whichever the project justifies. WordPress when you need to edit content constantly and want a familiar admin. A static build when speed and security matter more than a plugin ecosystem. Custom PHP and MySQL when the logic is genuinely yours. The choice is explained in the quote with its trade-offs, not presented as a foregone conclusion.
- Do you provide ongoing maintenance after launch?
- Thirty days of snag fixes are included after launch at no extra cost — anything that does not work as specified gets fixed. Beyond that there are monthly plans for updates, backups, monitoring and small changes. They are optional and cancellable; a site handed over properly does not require a retainer to keep running.
