The verdict in three sentences
For a group corporate site, a freelancer (8,000 to 20,000 EUR) works if the scope is short, the content is ready and an internal owner drives the project. An agency (25,000 to 75,000 EUR) becomes the rational choice as soon as you need multiple languages, an approval workflow and a 48-hour fix SLA. Over 3 years, the total cost gap shrinks sharply, from close to 3x to about +65%, while the risk gap stays wide.
What each option costs at signature
The initial quote is only part of the bill. Day rate, warranty and the scope actually covered weigh as much as the headline figure.
| Criterion (2026 order of magnitude, Amsterdam) | Freelancer | Agency |
|---|---|---|
| Corporate site, 15 to 30 pages | 8,000 to 20,000 EUR | 25,000 to 75,000 EUR |
| Developer day rate | 450 to 650 EUR | 700 to 950 EUR (senior profile billed) |
| Typical timeline | 6 to 12 weeks | 8 to 14 weeks |
| Post-launch warranty | Usually 3 months | 6 to 12 months |
| Bug-fix SLA | Subject to availability | Contractual, within 48 h |
| Multilingual NL/EN/DE | Often partial | Included or priced separately |
| People involved | 1 person | Project lead, designer, 1 to 2 developers |
A food-processing group exporting across Europe almost always needs Dutch, English and German, an investor or partner page and a press area. Those blocks are where the skills gap shows.
The risk matrix
For senior management the real issue is not price, it is what happens if something breaks or the key person disappears.
| Risk | Likelihood, freelancer | Likelihood, agency | Estimated impact |
|---|---|---|---|
| Key person unavailable (illness, departure, other client) | High | Low | Site frozen 2 to 8 weeks |
| Undocumented code, hard handover | Medium to high | Low | 4,000 to 11,000 EUR to take over |
| Delay overrun above 30% | Medium | Medium | Product launch pushed back |
| Unpatched security flaw | Medium | Low | Damage to group reputation |
| No access to accounts (hosting, domain) | Medium | Low | Full lock-out |
| Dispute over code ownership | Low to medium | Low | Legal costs |
A serious freelancer reduces these risks by contract: accounts in the company's name, documentation, code in a Git repository you own. Require those three clauses whoever you hire.
Total cost over 3 years
| 3-year item (estimate) | Freelancer | Agency |
|---|---|---|
| Build | 16,000 EUR | 45,000 EUR |
| Maintenance (400 / 800 EUR per month) | 14,400 EUR | 28,800 EUR |
| Enhancements (8 days per year) | 13,200 EUR | 19,200 EUR |
| Takeover or unplanned fixes | 8,000 EUR | 1,500 EUR |
| Estimated downtime cost | 5,500 EUR | 0 EUR |
| Total | 57,100 EUR | 94,500 EUR |
The initial gap (close to 3x) drops to about 65% over 3 years, and less again if the site carries recruitment, export or investor-relations stakes.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Sander, CEO of a 600-employee food-processing group headquartered in Amsterdam, gets two offers: a freelancer at 15,000 EUR and an agency at 47,000 EUR with a 12-month warranty and 48-hour SLA. The site must exist in Dutch, English and German in time for a trade fair in Cologne in 4 months.
He prices the risk: if the site is not ready for the fair, the group loses the equivalent of 2 distributor meetings, each worth an estimated 80,000 EUR in annual revenue. With a 35% delay probability on the freelancer side versus 10% for the agency, the expected cost of delay is 56,000 EUR versus 16,000 EUR. The 32,000 EUR price gap is more than offset: Sander picks the agency and keeps the freelancer for small out-of-scope changes.
FAQ
What is a web developer's day rate in Amsterdam in 2026?
Allow 450 to 650 EUR a day for an experienced freelancer and 700 to 950 EUR for a senior profile billed by an agency. Front-end or security specialists can exceed 1,000 EUR.
Is a 3-month warranty enough for a corporate site?
Rarely. Most defects surface during the first content updates, between month 2 and month 6. Aim for 6 to 12 months.
Can we combine a freelancer and an agency?
Yes. The agency owns design, architecture and the SLA, the freelancer handles small changes at 450 to 650 EUR a day. You then need a single code repository and shared deployment rules.
What should a fix SLA contain?
A response time (4 business hours, for example), a fix time by severity (48 h for blocking, 5 days for minor) and penalties or credits if it is missed.
How do we avoid depending on one person?
Require that the domain, hosting and Git repository are in your company's name, with 10 to 20 pages of documentation handed over at delivery.
Let's scope your project. Share the page count, languages and deadline for your corporate site: we propose a scope, a written SLA and an indicative budget you can compare line by line with other offers. Detailed quote within 48 h. WhatsApp +221 77 596 93 33.
