Web application development in Marseille

A website presents information. An application does work — it holds state, enforces rules, and produces something at the end. Most businesses that need the second one are running it on a spreadsheet nobody is allowed to sort, and paying for that in errors rather than in software. For Marseille businesses, quoted in EUR from $200, typically live in 10 days.

Why this matters for France specifically

The CNIL enforces cookie rules more aggressively than most EU regulators, and "refuse all" must be as easy as "accept all". A French site running a standard one-button banner is carrying a known, fineable defect.

How a Marseille 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 Marseille projects that document lists every page, every form, every integration and every third-party account the site will touch — priced in EUR, 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.

Professional services in Marseille

Accountants, solicitors, consultants and agencies sell judgement, which cannot be photographed. What converts instead is specificity: the sectors you actually work in, the size of client you actually serve, and named people with real biographies. A professional services site full of stock imagery and the word "bespoke" is indistinguishable from every competitor in Marseille.

Practically, the site's job is qualification rather than lead volume. Publishing your minimum engagement size loses you enquiries and saves you hours, and almost every practice I have built for concluded afterwards that it should have done it sooner.

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 Marseille to assert.

What I am not claiming about Marseille

Web application development in Marseille — common questions

What currency will I be invoiced in?
EUR. Quotes, milestones and the final invoice are all written in EUR so you are never comparing a converted figure against a local supplier's. Regarding tax: VAT at 20%, reverse-charged.
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.
How do you handle our customers' data under EU GDPR?
Your customer data is governed by the EU GDPR, enforced by the CNIL, and sending it to a developer in Pakistan is a restricted transfer. That is resolved by a DPA with EU Standard Contractual Clauses, published on this site and pre-signed before you send an enquiry — not drafted after you ask about it.
What payment methods can my Marseille checkout accept?
For France: Cartes Bancaires, Stripe, Lydia, and PayPal. 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 Marseille 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 hours will you be available to us in Marseille?
My working day lands at 06:00–15:00 in your time, which is roughly 6 hours inside a normal Marseille working day. In practice you can raise something in the morning and have it answered the same morning, and a scheduled call is easy to place at a civilised hour for both of us.
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.
