The verdict in three sentences
A 20 to 40 page corporate website needs 12 to 18 weeks from kickoff to launch, provided internal approvals keep pace. Development is almost never the bottleneck: around 40% of delays come from late content delivery, and 25% from approval chains that run too long. Promising a date to your leadership therefore means planning your own internal milestones as carefully as the agency's.
The typical corporate website schedule in 2026
These durations reflect an organisation in Toronto (public body, research institute, industry association or industrial company) with a bilingual site, a CMS with editorial workflow and a WCAG accessibility requirement.
| Phase | Low estimate | High estimate | Deliverables | Client-side approval |
|---|---|---|---|---|
| Scoping and workshops | 2 weeks | 3 weeks | Sitemap, personas, functional specification | Steering committee |
| UX and wireframes | 1 week | 2 weeks | Wireframes for 8 to 12 templates | Project lead + business units |
| Visual design | 2 weeks | 3 weeks | Desktop and mobile mockups, design system | Communications lead |
| Development and CMS integration | 5 weeks | 8 weeks | Site on staging environment | Demos every 2 weeks |
| Content integration | 2 weeks | 4 weeks (in parallel) | Written pages, media, translations | Writers + reviewers |
| Acceptance testing and accessibility | 2 weeks | 2 weeks | Test report, WCAG audit | Project lead |
| Launch and redirects | 2 days | 1 week | DNS switch, 301 redirect plan | Leadership |
| Total | 12 weeks | 18 weeks |
For a public body subject to procurement rules, add 6 to 10 weeks upstream to write the RFP, publish the tender and evaluate bids.
Causes of delay and their weight
Delays almost always follow the same patterns. Knowing them at scoping lets you neutralise them with written internal commitments.
| Cause of delay (2026 estimate) | Share of delays | Average delay | Countermeasure |
|---|---|---|---|
| Late content | 40% | 3 to 6 weeks | Content schedule from week 1, dedicated writer |
| Multiple approvals (leadership, legal, board) | 25% | 2 to 4 weeks | One final approver per phase, 5 business day turnaround |
| Scope change mid-project | 15% | 2 to 5 weeks | Phase 2 after launch, priced change order |
| Third-party integrations (SSO, directory, ERP) | 10% | 1 to 3 weeks | Technical access provided before development |
| Late client-side testing | 7% | 1 to 2 weeks | Named testers available for 2 weeks |
| Hosting or DNS issues | 3% | 2 to 7 days | Registrar access verified at scoping |
Speeding up without cutting quality
Three levers save 2 to 4 weeks: start writing content as soon as the sitemap is approved, approve design on 3 key templates rather than 12, and split the project into phase 1 (essential pages) and phase 2 (secondary features) delivered one to two months after launch.
Mini case study
Thomas, project lead at a research institute in Toronto, must give his board a launch date. The project covers 35 pages, two languages and a connection to the internal directory. Agency schedule: 14 weeks. Thomas lists his risks: 120 pages of content to be rewritten by 6 labs, and 3 approval levels.

Without action, internal history suggests 4 weeks of content delay and 2 weeks of approval delay, i.e. 20 weeks. Thomas hires a freelance writer for 6 weeks (EUR 5,400, i.e. 30 days at EUR 180, about USD 5,900) and cuts approvals to one approver per phase. He announces 15 weeks with one week of buffer. The EUR 5,400 extra cost avoids 5 weeks of internal project team extension, estimated at EUR 2,200 a week, i.e. EUR 11,000, for a net saving of EUR 5,600.
FAQ
Can a corporate website be built in under 8 weeks?
It is possible for 10 to 15 pages, a design adapted from an existing theme and content ready on day one. Beyond 20 pages with a custom design, 12 weeks remains the realistic minimum.
How long should acceptance testing take?
Two weeks for a 30-page site, with 2 to 3 internal testers available at least half a day each day. A WCAG accessibility audit adds 3 to 5 days if an external provider is involved.
Who should write the content?
The organisation knows its field best, but a professional web writer costs EUR 150 to 250 per optimised page. Over 40 pages, that is EUR 6,000 to 10,000 and removes the number one cause of delay.
What penalties apply if the agency is late?
Contracts often set 0.5 to 1% of the contract value per week of delay attributable to the provider, capped at 10%. Delays caused by client content or approvals are excluded.
Should there be a warranty period after launch?
Yes, a 1 to 3 month warranty covers bug fixes at no extra cost. It is distinct from ongoing maintenance, billed at EUR 150 to 400 a month.
