The verdict in three sentences
A premium corporate website ships in 8 to 14 weeks in 2026, from kick-off to launch, depending on page count and design complexity. The main delay factor is not the agency: it is the client (slow approvals, late content), easily adding 2 to 4 weeks. If you have a trade-show deadline, a fast-track is possible at +20% budget and heightened client availability.
The phase-by-phase plan
A premium project follows six phases, some overlapping (content is produced in parallel with design). Here are the 2026 durations for a 15 to 25 page site.
| Phase | Duration | Deliverable |
|---|---|---|
| Kick-off & workshops | 1 - 2 wk | Brief, sitemap |
| UX / wireframes | 2 - 3 wk | Approved wireframes |
| UI design | 3 - 4 wk | Design system, HD mockups |
| Development | 4 - 6 wk | Build, animations, CMS |
| Content (in parallel) | 2 - 3 wk | Copy, photos, video |
| QA & launch | 1 - 2 wk | Testing, fixes, deployment |
| Calendar total | 8 - 14 wk | Site in production |
Because content runs in parallel with design, the calendar total stays at 8-14 weeks even though the raw sum of phases looks larger.
Timeline by site tier
Not all sites need the same time. Here are the 2026 ranges by service level, at normal client availability.
| Tier | Pages | 2026 timeline | Indicative budget |
|---|---|---|---|
| Essential corporate | 5 - 8 | 4 - 6 wk | 4,000 - 8,000 EUR |
| Premium corporate | 15 - 25 | 8 - 14 wk | 12,000 - 25,000 EUR |
| Premium + multilingual | 25 - 40 | 12 - 18 wk | 20,000 - 40,000 EUR |
| Fast-track premium | 15 - 25 | 5 - 8 wk | +20% of budget |
Fast-track compresses the timeline by parallelizing more resources and imposing tight client approval slots.

A plan rarely slips because of the tech. Here are the real causes of delay and their quantified 2026 impact.

| Factor | Extra time | How to avoid it |
|---|---|---|
| Slow client approvals | +2 - 4 wk | Approval slots booked in advance |
| Late content delivery | +1 - 3 wk | Copywriting delegated to the agency |
| Multilingual | +25% | Translations started early |
| Mid-project scope additions | +1 - 4 wk | Frozen brief |
| Third-party integrations (CRM, ERP) | +1 - 2 wk | APIs documented upfront |
Approvals and content alone explain most overruns: locking them at kick-off secures the launch date.
Mini case study
Elodie, managing director of an industrial SMB in London, has a trade show in 9 weeks and wants an 18-page premium site. At standard pace, the timeline would be 11 weeks: too late. She chooses the fast-track at +20% (budget rising from 18,000 to 21,600 EUR), delegates copywriting to the agency and blocks two approval slots per week. Result: delivery in 7 weeks, in time for the show. The 3,600 EUR surcharge is negligible against the contracts generated on the stand thanks to a ready site.
FAQ
Can I really launch in under 8 weeks? Yes on fast-track, for a 15 to 25 page site, at +20% budget and flawless client availability to approve fast. Below 5 weeks for a premium build, quality suffers.
What takes the most time? Development (4-6 weeks) and UI design (3-4 weeks). But the real bottleneck in practice is client approvals and content delivery.
Does multilingual add much time? Yes, expect +25%, mainly for translations and integrating versions. Starting translations at kick-off limits the impact.
What happens if I deliver content late? Every week of content delay pushes QA by the same amount. Delegating copywriting to the agency removes this risk and smooths the plan.
Can I launch in stages? Yes. A two-wave launch (critical pages first, secondary ones next) lets you go live for a deadline while finishing the rest.
