How much does a custom website cost in 2026?

A custom website starts at 2,500 € for a brochure site and 7,000 € for an e-commerce store. These are our floor prices at Fautho Consulting, a web agency based in the Lille metropolitan area and specialised in Next.js development. The final price then depends on the scope of your project, but these figures give you a clear, honest starting point, without filling out a form just to get a rough range.

To set quick orders of magnitude:

• Brochure site : from 2,500 €, typically between 2,500 € and 6,000 € depending on the number of pages and the level of design.
• E-commerce : from 7,000 €, often between 7,000 € and 20,000 € depending on the catalogue and integrations.
• Business web application : on quote, because the functional scope varies enormously from one project to another.

These ranges are indicative. Only a personalised quote, drawn up after discussing your real needs, can set a fair price.

The price of a custom site mainly varies according to six factors: the number of pages, the level of design, the technical integrations, the content, the SEO and the maintenance. Understanding these levers helps you decide what is essential for your business and what can wait for a second phase.

The number of pages and the depth of content

The more pages and distinct templates a site has, the more design and build work it requires. A "Home", "Services" and "Contact" page does not demand the same effort as a site with a blog, local pages per city and detailed listings.

• Standard pages : presentation, services, about, contact. Quick to structure.
• Dynamic templates : blog, portfolio, case studies, where a single structure expands into dozens of pages.
• Specific pages : configurators, simulators, areas reserved for certain users.

The level of design

A bespoke design costs more than an adapted theme, but that is exactly what sets your brand apart. Between a clean, effective base and a bold art direction with custom animations and illustrations, the difference in working time is significant, and so is the difference in price.

The technical integrations

Every connection to an external service adds development and testing. Payment, booking, appointment scheduling, CRM, newsletter, stock management: these building blocks are often what pushes a quote upward.

• Payment : Stripe or other, with receipt and error handling.
• Booking and appointments : calendars, time slots, automatic confirmations.
• CRM and marketing : contact synchronisation, forms connected to your tools.

The content and SEO

A site that performs in search requires a structure built for Google from the start. Copywriting, photos, tag optimisation, loading speed and structured data are all part of the work. With Next.js, fast rendering and search-optimised output are a native advantage, which directly serves your visibility.

The price gap between these three project types comes from functional complexity, not just the number of pages. The more a site "does things" for the user, the more logic, security and testing it requires.

• Brochure site : from 2,500 €. It presents your business, generates contacts and calls. It is the baseline investment to exist seriously online.
• E-commerce site : from 7,000 €. It handles a catalogue, a cart, secure payments, stock and order tracking. Every function touches the customer's money, and therefore reliability.
• Web application : on quote. Customer portals, dashboards, business tools connected to your data. The price depends entirely on the features.

A website is not an expense, it is an asset. Well designed, it works for you every day, capturing leads while you sleep.

Our floor prices cover a complete site, ready to go live, not an empty shell to fill in later. Being transparent about what is included avoids unpleasant surprises and hidden extra costs.

• Design and concept tailored to your brand and your customers.
• Next.js development with clean, fast, maintainable code.
• Mobile version carefully crafted, since most of your visitors browse on a smartphone.
• SEO foundations : structure, tags, performance and indexing.
• Going live and support at launch.

A low-cost template often costs more over three years than a well-built custom site. The entry price is appealing, but the hidden fees pile up and end up exceeding the initial saving.

• Slowness : overloaded themes slow down display, which drives visitors away and penalises your search ranking.
• Maintenance : plugins to update, incompatibilities, security flaws, recurring bills.
• Early redesign : a site that does not convert or ages badly has to be rebuilt, and you pay twice.

Conversely, a custom site built for performance and conversion delivers a measurable return on investment: more quote requests, more sales, less maintenance to endure. The initial cost is higher, but the total cost of ownership is often lower.

Expect from 2,500 € for a brochure site and 7,000 € for an e-commerce store, with a final price adjusted to your real project. The right instinct is not to look for the cheapest, but for what is most profitable over time.
