Custom PHP and MySQL application development in Durham
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 Durham businesses, quoted in GBP from $200, typically live in 10 days.
What custom php and mysql application development includes for a Durham 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 Durham 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 Durham project is paid for, and why it is staged
Payment is split across milestones tied to things you can actually look at — a staging URL, a working checkout, a completed migration — rather than to dates on a calendar. You pay for a milestone after reviewing it, in GBP, which means at no point are you more than one stage out of pocket on work you have not seen.
This exists because the alternative puts all the risk on whichever side pays first, and across a border that asymmetry is the thing that makes people nervous. Staging it does not eliminate the risk; it caps it at one milestone, which is small enough to walk away from. That is a more honest offer than a guarantee I could not enforce from here anyway.
Manufacturing, wholesale and B2B in Durham
A B2B site in Durham serves two audiences with opposite needs. A buyer wants specifications, tolerances, lead times and a downloadable datasheet. A procurement officer wants your company registration, insurance, certifications and payment terms. Serving both from one undifferentiated "About" page serves neither of them.
The highest-value feature is almost always a searchable product or capability index carrying real part numbers, because that is what engineers search for. It is unglamorous, it is a database problem rather than a design problem, and it produces enquiries that arrive already qualified.
Structured data that is missing, wrong, or quietly lying
Schema markup is how a search engine reads what a page means rather than only what it says. Missing it costs you rich results. Getting it wrong is worse: marking up review stars you do not have, or a LocalBusiness at an address that is not yours, risks a manual action rather than a ranking.
Every page I build carries schema matching what is actually on it and nothing beyond that. The restraint is deliberate — this page uses Service and areaServed rather than LocalBusiness, precisely because there is no physical presence in Durham to assert.
What I am not claiming about Durham
- I have no office, postal address or phone number in Durham
- I cannot meet you in person, and if that is a requirement you should hire locally
- I am not claiming existing clients in Durham 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 Durham — common questions
- Can you migrate my Durham 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.
- 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.
- 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.
- 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.
- Do you actually work with businesses in Durham?
- Yes, remotely. I work with British clients from Islamabad, quoting in GBP and invoicing in GBP. I have no office, address or phone number in Durham and will not pretend otherwise. If your project needs someone physically present, hire locally — I will say so in the first reply rather than after a deposit.
