Custom PHP and MySQL application development in Oxford
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 Oxford businesses, quoted in GBP from $200, typically live in 10 days.
What custom php and mysql application development includes for a Oxford 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 |

| Payment rails available | Stripe, GoCardless for Direct Debit, and Klarna or Clearpay where basket sizes justify it |
| My day in Oxford 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.
How a Oxford build is scoped before anything is written
Scope is fixed in writing before development starts, and the number in that document is the number on the invoice. For Oxford projects that document lists every page, every form, every integration and every third-party account the site will touch — priced in GBP, not converted at the end from something else.
The reason this matters more than it sounds: almost every dispute in web development is a scope dispute wearing a different hat. "Can you just add" is how a three-day build becomes a three-week one. Fixing scope up front does not stop you changing your mind; it makes the cost of changing your mind visible before you commit to it, which is the only honest way to run a fixed price.
Trades and field services in Oxford
Builders, electricians, plumbers, roofers and installers share one problem: the customer is deciding on their phone, often standing in the room with the problem, and they will call the first firm that looks like it will pick up. Three things decide it — the phone number tappable in the header, a coverage list naming their town, and photographs of your own finished work rather than stock.
The thing trades sites most often get wrong is the quote form. Asking for a full address, a project budget and a preferred start date before anything else is a form built for your admin convenience, not for the customer. Two fields and a photo upload will produce more enquiries than eight fields ever will, and the rest can be collected on the call you just earned.
Images shipped at ten times the size they display
A hero photograph exported at 4000 pixels wide and displayed at 400 is the most common single cause of a slow page. The browser downloads all of it and then discards most of it. On a phone over mobile data that is several seconds spent waiting for pixels nobody will ever see.
The fix is generating each image at the sizes actually used, serving AVIF or WebP with a fallback, and setting explicit width and height so the layout does not jump while they load. It is mechanical work with a directly measurable result, which makes it the first thing worth doing on almost any Oxford site.
What I am not claiming about Oxford
- I have no office, postal address or phone number in Oxford
- I cannot meet you in person, and if that is a requirement you should hire locally
- I am not claiming existing clients in Oxford 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 Oxford — common questions
- What hours will you be available to us in Oxford?
- My standard day lands at 05:00–14:00 your time — about 5 hours of genuine overlap with a normal Oxford working day. That is enough for one reliable daily window rather than constant back-and-forth, so Oxford projects run on written updates plus one scheduled call a week.
- How long does a Oxford 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.
- 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.
- 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.
- Who owns the website when it is finished?
- You do, completely. The domain is registered in your name, hosting sits in your account, the code lives in a repository you control, and any payment provider account is opened in your business name. Credentials are handed to you as they are created rather than at the end, so you are never locked out of your own site.
- What currency will I be invoiced in?
- GBP. Quotes, milestones and the final invoice are all written in GBP so you are never comparing a converted figure against a local supplier's. Regarding tax: 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.
- What payment methods can my Oxford 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.
