Custom PHP and MySQL application development in Richmond
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 Richmond businesses, quoted in GBP from $200, typically live in 10 days.
What custom php and mysql application development includes for a Richmond 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 Richmond 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 Richmond sites are built to be edited by you
A site you cannot update is a site that decays. Prices go stale, staff leave, the opening hours are wrong for six months. So the parts of a Richmond build that change often — text, images, prices, opening hours, team members — are editable by you without touching code or paying me.
That is a design decision with a cost: it takes longer to build an editable block than a hard-coded one. It is worth it because the alternative is a maintenance dependency that benefits me and not you, and a developer whose income depends on you being unable to change your own opening hours is not aligned with your interests.
Healthcare and clinics in Richmond
Clinics carry a compliance weight most businesses do not. Appointment forms collect health information, which is a special category under UK GDPR, and it cannot be emailed to a generic inbox or written to a plain-text log. That constraint has to shape the build rather than be bolted onto it afterwards.
Beyond compliance the deciding factor is reassurance: practitioner names, registrations a patient can verify, honest pricing, and what actually happens at a first appointment. Anxiety is why people delay booking, and a site that reduces it outperforms one that merely looks modern.
A redesign that quietly deleted the rankings
The classic disaster: a new site launches, looks far better, and organic enquiries fall off a cliff within a fortnight. The cause is almost always identical — the URLs changed and nothing was redirected, so every page that had accumulated years of authority now returns a 404.
Preventing it is a redirect map built before launch: every old URL to its closest new equivalent with a 301, and anything without an equivalent pointed at the nearest relevant page rather than the homepage. If your Richmond site is being redesigned by anyone, ask to see that map. If it does not exist, that is the entire risk in one document.
What I am not claiming about Richmond
- I have no office, postal address or phone number in Richmond
- I cannot meet you in person, and if that is a requirement you should hire locally
- I am not claiming existing clients in Richmond 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 Richmond — common questions
- 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.
- 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.
- Will the site actually rank in Richmond search results?
- The build handles what is technically controllable: crawlable HTML, correct headings, structured data, fast pages, a clean sitemap and Search Console set up on day one. Ranking also depends on your competitors, your domain's age and the links pointing at you, which no developer controls. Anyone guaranteeing a position is guessing or lying.
- 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.
- Can you migrate my Richmond site without losing rankings?
- Yes, and the redirect map is the whole job. Every existing URL is mapped to its new equivalent with a 301 before launch, and anything with no equivalent goes to the closest relevant page rather than the homepage. Sites lose rankings in migration because that mapping was skipped, not because migration is inherently risky.
- Do I need to provide the content and images?
- Content, yes — you know your business and I do not. I will restructure and edit what you send so it reads for the web, and I will tell you where a section is missing. Photography is worth paying a local photographer for; stock images of people in offices are recognisable as stock and quietly cost you credibility.
