The verdict in three sentences
For a B2B brochure website in London, the freelancer (4,000-9,000 EUR) wins on price, the agency (12,000-30,000 EUR) on continuity and SLA, the collective (8,000-18,000 EUR) sits in between. The real criterion is not price but the criticality of the site: the more revenue it carries, the more bus factor and maintenance matter. Choose by the risk you can absorb, not by the quote line alone.
Day rates and project cost by profile in 2026
Total cost depends on the day rate and the number of person-days mobilised.
| Profile | 2026 day rate | Brochure site project cost | Timeline |
|---|---|---|---|
| Freelancer | 350 - 550 EUR | 4,000 - 9,000 EUR | 4-8 weeks |
| Freelance collective | 400 - 600 EUR | 8,000 - 18,000 EUR | 5-9 weeks |
| Structured agency | 450 - 750 EUR | 12,000 - 30,000 EUR | 6-10 weeks |
The agency charges a higher day rate but pools design, development, project management and QA, reducing overrun risk on complex projects.
Risks and guarantees compared
Price says nothing about risk. Here is what truly separates the three options.
| Criterion | Freelancer | Collective | Agency |
|---|---|---|---|
| Bus factor (single-person dependency) | High | Medium | Low |
| Contractual SLA | Rare | Variable | Standard |
| Structured maintenance | On availability | Variable | Yes |
| 3-year continuity | Uncertain | Medium | High |
| Single point of contact | Yes | Sometimes | Yes (project manager) |

Mini case study
Camille, procurement lead of a B2B services SME in London, must rebuild the site that generates 30 % of sales leads. A freelancer quotes 7,000 EUR, an agency 16,000 EUR with maintenance at 300 EUR/month and a 24-hour recovery SLA. The site drives 30 % of 1,200,000 EUR annual revenue, i.e. 360,000 EUR. A 5-day outage with no SLA would cost about 7,400 EUR in lost leads (360,000 / 240 working days x 5). On such a critical site, the 9,000 EUR agency premium is absorbed by the first outage the SLA prevents. She picks the agency.
FAQ
Which is cheapest: freelancer, collective or agency? The freelancer, at 4,000-9,000 EUR project cost versus 12,000-30,000 EUR for an agency. But the 3-year total cost, including maintenance and rupture risk, narrows the gap.
When should I choose an agency over a freelancer? As soon as the site is strategic, generates revenue or requires an SLA. Continuity, structured maintenance and low bus factor then justify the 8,000 to 20,000 EUR premium.
What is the bus factor? It is the risk of depending on a single person: if a freelancer becomes unavailable, the project stalls. An agency pools skills and reduces this risk to a low level.
Is a collective a good compromise? Often yes: 8,000-18,000 EUR for varied skills, with a medium bus factor. Check, however, who owns maintenance and SLA over time.
How do I compare two quotes fairly? Insist on the person-day and day-rate breakdown, monthly maintenance and SLA. A quote missing these three cannot be compared to another.
