The verdict in three sentences
A serious B2B brochure site takes 8 to 12 weeks, not the 4 weeks promised by loss-leader offers. The critical path is almost never development: it is content and approval cycles that derail 80% of projects. A fast-track before a trade show is possible but costs +25 to +40% and requires content ready on day one.
The realistic plan phase by phase
Here is the 2026 sequence for an 8-to-15-page B2B brochure site. Phases partly overlap, but content conditions everything else.
| Phase | Duration | Deliverable | Who leads |
|---|---|---|---|
| Scoping & UX | 1-2 wks | Sitemap, wireframes | Agency + client |
| UI design | 2-3 wks | Approved mockups | Agency |
| Development | 3-4 wks | Working site in staging | Agency |
| Content | 2 wks (in //) | Copy, photos, video | Client |
| QA & SEO | 1 wk | Tests, fixes, go-live | Agency + client |
| Total | 8-12 wks | Site in production | - |
Content runs in parallel but remains the top delay factor: a technically ready site often waits 3 weeks for copy that has not been delivered.
Fast-track surcharge and the 3 causes of delay
Compressing the plan is possible but has a price. Here is the 2026 impact of a fast-track and the weight of the three most frequent delay causes on a EUR 13,000 project.
| Fast-track lever | Effect on timeline | Surcharge |
|---|---|---|
| Reinforced team | -2 to -3 wks | +15 - 25% |
| Copy written by agency | -2 wks | +EUR 800 - 2,500 |
| Weekend sprints | -1 wk | +10 - 15% |
| Delay cause | Frequency | Time added |
| Content not ready | ~45% of projects | 2-3 wks |
| Slow approvals | ~25% | 1-2 wks |
| Scope creep | ~15% | 2-4 wks |
A +30% fast-track that brings 12 weeks down to 8 only makes sense if your content is ready: otherwise you pay for speed without getting it.

Mini case study
Elsa, marketing lead at a B2B software vendor in Berlin, wants the site live before a trade show in 10 weeks (budget EUR 13,000). On a standard plan (8-12 wks), the risk of missing the show is real because of content. She picks a targeted fast-track: reinforced team (+18%, i.e. +EUR 2,340) and copy handed to the agency (+EUR 1,800), for a total of EUR 17,140. Result: delivery in 8 weeks, two weeks of margin before the show. Knowing that a single signature from the show is worth about EUR 25,000 in annual contract, the EUR 4,140 surcharge pays off from the first qualified lead. She approves the fast-track.
FAQ
How long for a B2B brochure site in 2026? Budget 8 to 12 weeks for an 8-to-15-page site with custom design. The 4-week offers rely on templates and content already prepared.
Can we go faster for a trade show? Yes, a fast-track brings the timeline to 6-8 weeks, but costs +25 to +40% and requires content ready or handed to the agency from the start.
What is the top cause of delay? Content not delivered, in about 45% of projects, adding 2 to 3 weeks. A technically ready site then waits for the client's copy.
Who provides the content? The client by default, but the agency can write for EUR 800 to 2,500. Settling this at scoping avoids the most common delay.
Is the fast-track worth the surcharge? It is justified when the date is tied to a revenue-generating event: a show signing a EUR 25,000 contract easily pays back a EUR 3,000-4,000 surcharge.
