How long a website takes to build in 2026: what is really realistic

Why quoted timelines are often wrong

When an SME in French-speaking Switzerland consults 3 agencies about a corporate site, it typically receives 3 quotes with 3 radically different timelines: 4 weeks, 8 weeks, 16 weeks, for services that look comparable on paper. Three reasons explain the gap, and they add up.

The salesperson quotes short to close the deal. An agency’s salesperson knows that a client would rather hear “6 weeks” than “12 weeks”. They underestimate the timeline to win the contract, knowing that the overrun will be defensible once the project is under way.

Agencies measure differently. Agency A counts “6 weeks” of pure development, without the scoping, without the content, without the client’s corrections. Agency B counts “12 weeks” end to end, from the signed brief to the site in production. The figures look different, but the real timeline is almost identical.

Assumptions about the client’s availability differ. An optimistic agency assumes you will be available 2 to 3 hours a week for the project. In reality, it is often 30 minutes a week, with gaps of 2 to 3 weeks (holidays, business emergencies, travel). This difference explains 50% of delays.

To compare quotes, you therefore need the real timelines in 2026 by type of project, and the factors that influence them.

Timeline by type of project

Simple business website (5 to 10 pages)

Typical quoted timeline: 4 weeks Healthy real timeline: 4 to 6 weeks Timeline if the project drifts: 8 to 12 weeks

Breakdown:

• Scoping and brief: 1 week
• Design and mockups: 1 to 2 weeks
• Development: 1 to 2 weeks
• Content, corrections, QA: 1 week

Conditions for holding to 4 weeks: a simple design without elaborate art direction, content supplied by the client on time, quick approval of the mockups in 1 round. If one of these conditions falls through, it slips to 6 weeks.

At Voren, the Essential business website plan is calibrated for 4 weeks. It is achievable because the conditions are written into the contract.

Corporate business website (15 to 30 pages, animations, partly multilingual)

Typical quoted timeline: 8 weeks Healthy real timeline: 6 to 10 weeks Timeline if the project drifts: 14 to 20 weeks

Breakdown:

• Strategic scoping: 1 to 2 weeks
• Art direction and mockups: 2 to 3 weeks (often the item that drifts)
• Development: 2 to 3 weeks
• Content, translations, corrections, QA: 2 weeks

Conditions for holding to 6 weeks: art direction defined upfront, content written by a dedicated copywriter (not the client), translations delivered in parallel with development, a responsive team on the client side.

Voren’s Premium business website plan is calibrated for 6 weeks.

Bespoke / fully multilingual business website

Typical quoted timeline: 12 weeks Healthy real timeline: 8 to 14 weeks Timeline if the project drifts: 16 to 24 weeks

For bespoke sites with elaborate art direction, 4 languages (FR/DE/IT/EN), original animations and complex API integrations. Voren Bespoke: 8 to 10 weeks, written into the contract.

Essential e-commerce (up to 50 products)

Typical quoted timeline: 8 weeks Healthy real timeline: 8 to 12 weeks Timeline if the project drifts: 16 to 24 weeks

E-commerce is more complex than a business website, for 3 reasons:

• A product catalogue to structure and fill (often underestimated)
• A payment integration (Stripe, TWINT) to test thoroughly
• Shipping logistics to configure (zones, fees, returns)

Voren E-commerce Essential: 8 weeks written into the contract, on the basis that the client supplies a ready product catalogue (texts + photos).

Advanced e-commerce (500+ products, ERP, multilingual)

Typical quoted timeline: 16 weeks Healthy real timeline: 14 to 24 weeks

ERP integrations (Bexio, Sage, Abacus) add 2 to 4 weeks depending on complexity. Multilingual adds 2 to 3 weeks. Voren E-commerce Premium: 12 weeks written into the contract.

Web app / SaaS

Typical quoted timeline: 16 weeks Healthy real timeline: 16 to 30 weeks

Web apps are the projects with the most variable timelines, because functional complexity varies enormously. A simple MVP in 10 weeks, a multi-tenant SaaS platform in 9 to 12 months.

Voren Web app Essential: 10 weeks for an MVP. Web app Premium: 16 weeks. Bespoke: 20 to 30 weeks.

The 5 most common causes of delay

Based on our experience of the last 30 projects delivered between 2024 and 2026, here are the factors that make timelines slip.

Factor 1: content not ready

50% of projects slip because of the content. The client thought they would supply the texts and photos quickly. Three months later, 5 pages of text and 30 product photos are still missing.

Solution: if you know you won’t have time to write, put the content in your contract with your provider from the brief onwards. At Voren, copywriting is included in the Essential and Premium plans.

Factor 2: back-and-forth on the mockups

The client asks for 3 major iterations of the design because they had not anticipated their needs. Each iteration costs 1 week on the schedule.

Solution: spend time on strategic scoping before production. More time upstream, fewer revisions downstream. Agree the moodboard with the client before the first mockup.

Factor 3: late approval

The client takes 10 days to approve a mockup that was sent to them for approval within 48 hours. Three late approvals add up to a month’s delay.

Solution: sign a client SLA from the brief onwards, with contractual approval times (typically 48 or 72 hours). Voren includes it in every plan.

Factor 4: scope creep

During the project, the client adds features that were not planned (“can we also have a newsletter? a blog section? a client area?”). Each addition eats into the schedule and the margin.

Solution: every change of scope triggers a written amendment stating its impact on price and timeline, even an informal request meant to slip through “as a bonus”.

Factor 5: late technical choices

Major technical decisions (CMS, authentication, payment) taken in the middle of the project rather than at the scoping stage. Each late hesitation costs 1 to 2 weeks.

Solution: finish the technical scoping before development starts. Voren signs a technical scoping document before development.

The Voren method for meeting deadlines

Voren meets its deadlines, and the method comes down to 5 points.

1. Contractual timeline: the timeline is written into the contract, step by step. This discipline forces us to plan seriously.
2. Upfront scoping: 1 to 2 weeks of scoping before development, with a signed brief that sets out the scope.
3. Client SLA: contractual approval times on the client side (typically 72 hours). If they are exceeded, the agency is not responsible for the delay.
4. Short sprints: weekly demos with visible deliverables; the client never spends 6 weeks in a “tunnel” without seeing anything.
5. Industrialised production: a network of qualified freelancers can absorb peaks, so the project never hinges on a single person.
