Custom PHP and MySQL application development in Utrecht

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 Utrecht businesses, quoted in EUR from $200, typically live in 10 days.

Why this matters for Netherlands specifically

iDEAL accounts for the majority of Dutch online payments. A Netherlands store that leads with card fields and buries iDEAL is losing conversions at the last step for no reason other than build order.

What actually ships when a Utrecht project goes live

A handover for a Utrecht client is not a link and a login. It is the repository, the hosting account in your name, the domain registered to you, the payment provider account under your business, and a written record of every credential as it was created rather than dumped in one email at the end.

The test I apply is uncomfortable but correct: if I disappeared tomorrow, could another developer pick this up on Monday without calling me? If the answer is no, the handover is not finished. That standard is why the documentation takes a day I do not bill separately — it is part of the build, not an upsell.

Retail and e-commerce in Utrecht

A store is judged at the checkout, not the homepage. For Netherlands that means the payment methods have to match what people actually use — iDEAL above all else, plus Mollie, Stripe and SEPA — and the cart has to survive a slow connection and a page refresh. Most abandoned baskets are not indecision; they are a checkout that broke and gave no reason why.

The second issue is stock truth. A product page saying "in stock" when it is not costs you the sale and the customer, and the fix is unglamorous plumbing between wherever your stock actually lives and the storefront. That is worth a day of work far more than the product photography carousel is.

The contact form that silently fails

The most expensive bug on a small business website makes no noise at all. A form posts, shows a thank-you message, and the email never arrives — usually because the host's mail function is unauthenticated and the receiving server drops it without a bounce. The business concludes demand fell.

The fix is authenticated SMTP with SPF, DKIM and DMARC configured on the sending domain, plus a database write so a submission survives even when delivery fails. If you are unsure whether your Utrecht site has this problem, submit your own form from a phone on mobile data and see what actually arrives.

What I am not claiming about Utrecht

Custom PHP and MySQL application development in Utrecht — common questions

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.
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.
Will the site actually rank in Utrecht 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.
Can you migrate my Utrecht 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 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 actually work with businesses in Utrecht?
Yes, remotely. I work with Dutch clients from Islamabad, quoting in EUR and invoicing in EUR. I have no office, address or phone number in Utrecht 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.
