The verdict in three sentences
A realistic premium B2B website ships in 6 to 10 weeks, framing included. The bottleneck is almost never development but content sign-off (copy, photos, internal reviews) on the client side. Plan a +15 % buffer on the announced timeline: it absorbs validation back-and-forth and protects your go-live date.
The milestone-by-milestone schedule
Each phase has a typical duration and an exit deliverable. Some overlap: content is prepared alongside design.
| Phase | Typical duration | Exit deliverable | Who blocks |
|---|---|---|---|
| 1. Framing | 1 week | Approved site map, wireframes | Client (decisions) |
| 2. Design | 2-3 weeks | Approved UI mockups | Client (sign-off) |
| 3. Content (parallel) | 2 weeks | Copy + photos delivered | Client (writing) |
| 4. Development | 3-4 weeks | Site built on staging | Agency |
| 5. UAT | 1 week | Fixes + final approval | Both |
| Total | 6-10 weeks | Go-live | — |
In this schedule, only phase 4 truly depends on the agency: three of the five milestones are blocked by client availability and decisions.
Why content is the real bottleneck
Teams systematically underestimate content production and sign-off time. It is the number-one cause of slippage in 2026.
| Delay cause | Frequency | Buffer to plan |
|---|---|---|
| Slow content sign-off | Very high | +2 to +3 weeks |
| Photos/videos not ready | High | +1 to +2 weeks |
| Multiple internal decision makers | High | +1 week per round |
| Mid-project scope changes | Medium | +1 to +2 weeks |
| SEO migration/redirects | Medium | +3 to +5 days |
Naming a single decision-making point of contact on the client side and delivering content before design starts cuts the total timeline by 2 to 3 weeks.
Mini case study
Mark, marketing director of a B2B hospitality group in Toronto, wants his site live for a conference in 8 weeks. The agency schedule is 7 weeks excluding buffer. He applies the +15 % rule, about 1 week of slack, and sets go-live at exactly 8 weeks. Narrowly avoided mistake: content sign-off by three internal decision makers takes 9 days instead of 3. Thanks to the buffer and a single point of contact named in phase 1, the site ships at 7 weeks and 5 days, in time for the conference.

FAQ
Can a website really ship in 3 weeks?
Only a simple template site with content already ready. A premium B2B site with custom design, content to produce and internal sign-offs realistically needs 6 to 10 weeks.
What is the main delay factor?
Client-side content sign-off, by far. Copy, photos and feedback from several internal decision makers frequently add 2 to 3 weeks if nothing is framed upfront.
How much buffer should I plan?
About +15 % on the announced timeline. On a 7-week project that is roughly one week of slack, which absorbs validation back-and-forth.
How can I speed up the project?
Name a single decision-making point of contact, deliver content before design, and limit review rounds. These three steps can save 2 to 3 weeks.
Is development the longest phase?
No. Development (3-4 weeks) is the most predictable because it depends on the agency. It is the client-dependent phases that derail schedules.
