The verdict in three sentences
An Amsterdam law firm website with online booking costs between 9,000 and 20,000 EUR excl. VAT in 2026, delivered in 7 to 11 weeks. The decisive conversion factor is organisation by practice area (business, employment, real estate) paired with smooth booking, which brings up to +40 % consultation requests. The challenge is combining commercial effectiveness with strict respect for professional conduct rules (measured advertising).
Feature grid and budget
A firm sells not a product but expertise and trust. The site must reassure, qualify and ease first contact without ever slipping into prohibited touting.
| Package | 2026 price (EUR excl. VAT) | Timeline | Key features |
|---|---|---|---|
| Controlled presence | 9,000 - 11,000 | 7 wks | 8 practice pages, bios, form, legal blog |
| Connected firm | 12,000 - 15,000 | 8-9 wks | + online booking, qualification by area, newsletter |
| Premium firm | 16,000 - 20,000 | 10-11 wks | + secure client portal, deposit payment, multilingual |
| Client portal (option) | 2,500 - 5,000 | +2 wks | Encrypted document sharing, matter tracking |
| Maintenance / yr | 2,000 - 4,000 | — | Security, backups, legal updates |
The secure client portal is the module that sets a modern firm apart: it builds loyalty and cuts administrative back-and-forth, but demands heightened security.
Online booking and conduct rules: what is allowed
Online booking is fully compatible with professional rules, provided it stays factual. Here are the practices and their status (2026 ballpark, confirm with the bar).
| Practice | Status | Conversion impact |
|---|---|---|
| Online booking by practice area | Allowed | +25 to +40 % |
| Clear indicative fee ranges | Allowed and recommended | +15 % trust |
| Verified client reviews | Regulated | +10 to +20 % |
| Comparison with other firms | Prohibited | — |
| Promise of outcome | Prohibited | — |
| Expertise content (articles, legal FAQ) | Allowed and effective | SEO traffic + |
Showing an indicative fee range and offering a paid or free scoping consultation filters requests and raises lead quality.
Mini case study
Ms Lecomte, partner at a 6-lawyer business-law firm in central Amsterdam. Her site dated from 2018, with no booking. She invests 14,500 EUR excl. VAT in a "connected firm" site with online booking and qualification by area.
Before: 8 consultation requests a month. After 5 months: 13 requests/month, i.e. +62 % (beyond the +40 % target), with a higher share in more profitable business law. With an average first-matter fee of 3,500 EUR and a 30 % conversion rate, the 5 extra requests a month represent about 5,250 EUR of additional monthly revenue, paying back the site in under 3 months.

FAQ
Is online booking compliant with conduct rules?
Yes. It is seen as a facilitation tool, not prohibited advertising. Stay factual, with no promise of outcome or disparaging comparison.
What is a realistic timeline for a law firm site in Amsterdam?
Between 7 and 11 weeks depending on options. The secure client portal adds about 2 weeks of development and security testing.
Should fees be displayed?
Not mandatory but strongly recommended: an indicative range reassures and filters out unqualified requests, improving the closing rate.
Is a client portal worth the investment?
For a firm handling long matters (business, real estate), yes: it cuts administrative exchanges and builds loyalty. Budget an extra 2,500 to 5,000 EUR.
How to handle multilingual for international clients?
An EN/local-language site covers most business clients. Each extra language adds about 15 to 20 % to content and maintenance cost.
