How Long Does It Take to Build a Professional Website?

A professional website takes between 1 week and 9 months to build, depending on what you are building. The right question is not “how long” but “what type of site, and how ready is your side”. The things that delay you are always the same: content, slow decisions, integrations, and internal approvals.

Here are real timelines by type, based on projects we have shipped.

Landing page: 1-3 weeks

One page, single focus, contact form or WhatsApp button. If copy, photos, and logo are ready, it is 5-10 business days. Starting from zero on copy and photos: 2-3 weeks.

What it includes:

• 1 page, responsive design
• Form with transactional email
• Analytics wired in
• Deploy and domain

When it stretches: copy is not ready, photos still need to be shot, or there are 3 rounds of approval with different stakeholders.

Corporate site: 4-8 weeks

5-15 pages, optional blog, sometimes multilingual, CMS so the client can edit later.

Typical distribution:

• Week 1: discovery, sitemap, wireframes
• Week 2-3: visual design of key pages
• Week 4-6: development
• Week 7: content, QA, adjustments
• Week 8: launch and handoff

What we see slipping:

• Client-side content: text arriving 4 weeks late. Bottleneck #1.
• Approvals: when design has to pass marketing, management, and an external advisor.
• Product or team photos: photoshoot rescheduled twice.

With all that ready on day one, a solid corporate site ships in 4 weeks. Without it, 8.

E-commerce: 8-16 weeks

Here the platform decides:

• Managed Shopify with premium theme: 4-8 weeks if the catalog is clear.
• WooCommerce on WordPress: 6-10 weeks with proven plugins.
• Custom with Astro, Next.js, or Medusa: 12-20 weeks.

The non-negotiable steps live in How to build your e-commerce website step by step. To decide between Shopify and custom, see Why you should have a custom e-commerce site.

What slows e-commerce the most:

• Gateway certification: BAC and Promerica take 4-8 weeks to certify. If it does not start in week 1, the launch slips by that alone.
• Catalog: loading 500 products with good photos, descriptions, and variants takes 6-10 weeks if nobody planned it.
• ERP integrations: every custom internal system adds 2-4 weeks.

Web app: 4-9 months

When we talk about web apps with login, database, and business logic, the ranges are:

• Functional MVP with 3-5 modules: 3-5 months
• Web app with 8-12 modules: 6-9 months
• Enterprise system with multiple integrations: 9-18 months

What typically slows a web app:

• Open product decisions: “what happens if the user does X?” with no clear answer.
• Legacy integrations: old or undocumented APIs.
• Mid-project scope changes: “while we are at it, let’s add…”
• Real-user validation: if nobody tests until month 5, big problems surface late.

To figure out if your project is a web app or something else, see Website vs web app vs SaaS and the scale stages in From MVP to scale.

What always slows you down

After several years shipping projects, the delays are the same. By frequency:

1. Client-side content

Copy, photos, video, high-res logos, certificates, and catalog data are almost never ready on the promised date. If the client team does not assign one content owner with real blocked time, the project slips 30-60%.

2. Slow decisions

“Let me check with my partner” repeated at every milestone adds weeks. Defining who decides what, and by when, at kickoff saves a month and a half.

3. Integrations with existing systems

Connecting to your ERP, accounting, CRM, internal inventory, or Costa Rican e-invoicing (Hacienda) always takes longer than planned. Undocumented APIs, credentials nobody has, sandbox that does not respond. Reserve 2-4 extra weeks per integration.

4. Internal approvals

If your organization needs design to pass 4 people, development does not start until all 4 sign off. If one is on vacation, you wait. Shortening this requires client discipline, not provider discipline.

5. Scope creep

“While we are at it, can we also add…” Each add-on looks small, but 5 small ones equal 6-8 weeks. On fixed-scope projects, changes go into V2.

More on the real cost of improvising any of this in The real cost of a bad development agency and The true cost of technical debt.

How to shorten it without sacrificing quality

What actually accelerates:

• Content ready before kickoff: copy, photos, SVG logo, catalog data in a Sheet.
• One assigned decision-maker: a single client-side person with authority to approve.
• Short daily or weekly status: 15 minutes a day or 1 hour a week, not 2-hour meetings.
• Sprint-based delivery: deliverables every 2 weeks, not “I’ll let you know when it is ready”.
• Start integrations in week 1: do not wait for design to finish.
• Accept imperfection in V1: anything non-critical goes to V2. Shipping in 6 weeks and improving beats “shipping perfect in 6 months” every time.
