The verdict in three sentences
In 2026, a brochure website for an independent professional costs EUR 2,500 to 7,000 excl. tax and ships in 3 to 5 weeks, with expertise pages, online booking and GDPR compliance. Well ranked locally, it generates 5 to 15 contacts/month at a cost per lead of EUR 15 to 45. Without a site, 60 to 70 % of prospects who check online switch to the visible competitor: invisibility costs more than the site.
What a professional-services website costs
Doctor, lawyer, accountant, consultant, architect: the need is the same, a credible site that reassures and enables contact. Here are the tiers and 2026 prices.
| Tier | Content | Price excl. tax | Timeline |
|---|---|---|---|
| Essential | 4 to 5 pages, contact, GDPR notices | EUR 2,500 to 3,500 | 3 weeks |
| Professional | + expertise pages, blog, online booking | EUR 3,500 to 5,000 | 4 weeks |
| Premium | + advanced local SEO, multilingual, reviews | EUR 5,000 to 7,000 | 5 weeks |
Add EUR 400 to 900/year for hosting and maintenance, plus an optional local SEO budget of EUR 150 to 400/month to accelerate visibility.
What drives conversion
A professional does not sell a product but trust. Three elements weigh most on turning a visitor into a contact. Here is their measured effect.
| Element | Conversion effect | Indicative cost excl. tax |
|---|---|---|
| Online booking | +30 to 50 % completed contacts | EUR 300 to 900 |
| Detailed expertise pages | +trust, better SEO | included |
| Verified client reviews | +20 to 35 % credibility | EUR 200 to 500 |
| Local SEO (listing + city pages) | 5 to 15 contacts/month | EUR 150 to 400/month |
| Visible GDPR compliance | Reduces form abandonment | included |
Online booking is the best investment: it removes phone back-and-forth and captures requests outside opening hours, when the patient or client is truly searching.
Mini case study
Mr. Diop, partner at a consulting firm in Lyon, invests EUR 4,500 excl. tax in a professional site with expertise pages, online booking and local SEO, delivered in 4 weeks. He adds EUR 250/month of local SEO. After 4 months, the site generates about 9 qualified contacts/month at a cost per lead of around EUR 30.
Of those 9 contacts, he converts 2 new clients a month, each worth on average EUR 1,800 in engagement. That is EUR 3,600 of monthly revenue attributable to the site, against a total cost of EUR 250/month of SEO plus site amortisation. The site pays for itself in under 3 months of activity, and each following month local SEO compounds visibility with no marginal production cost.

FAQ
Does an independent professional really need a website?
Yes: 60 to 70 % of prospects check a professional online before contacting them. Without a credible site, they choose the visible competitor; the absence of a site is a silent loss of clients.
How many contacts does a well-ranked site generate?
Between 5 and 15 contacts per month depending on area and competition, at a cost per lead of EUR 15 to 45. Local SEO and online booking are the two levers that raise this figure.
Is online booking essential?
It is not mandatory but increases completed contacts by 30 to 50 %. It captures out-of-hours requests and removes phone friction, which makes it pay off quickly.
What GDPR obligations for a professional-services site?
Legal notices, privacy policy, form consent and data security. For healthcare professions, caution on sensitive data requires compliant hosting and forms.
How long to go live?
From 3 to 5 weeks depending on the tier. The essential tier ships in 3 weeks if content (bio, expertise, photos) is ready at scoping.
