Quick answer: A simple 5-page brochure site takes about 2 to 4 weeks, a mid-size business website with custom design and a content management system runs 6 to 10 weeks, and a complex site with e-commerce, custom features, or integrations can take 3 to 6 months. The biggest swing factor isn't design or coding — it's how fast you supply content, feedback, and approvals.

Key takeaways

Small brochure sites (5–10 pages, template-based) typically finish in 2 to 4 weeks; custom-designed business sites take 6 to 10 weeks.
E-commerce sites and platforms with custom functionality or third-party integrations commonly take 12 to 24 weeks.
Client response time — getting content, images, and feedback back to the developer — is the single most common cause of delay on any project size.
Discovery and planning (defining pages, features, and goals before design starts) usually takes 3 to 10 days but prevents the most expensive rework later.

Step 1: Define Scope and Goals Before You Contact Anyone (2–5 days)

Before you request a quote, write down what the site needs to do — not just what it should look like. A restaurant site that needs online ordering has a fundamentally different timeline than one that just needs a menu and hours.

Nail down these basics first:

List every page you think you need (Home, About, Services, Contact, Blog, etc.).
Decide if you need e-commerce, booking, membership logins, or other functionality.
Gather examples of 2–3 sites whose design or layout you like.
Set a realistic budget range so developers can tell you what's achievable in it.
Identify who on your team has final sign-off authority — one person, not a committee.

This step doesn't involve the developer yet, but it shapes everything after. Vague scope is the number one reason quoted timelines slip, because "add a few features" mid-project pushes back every phase that follows.

Step 2: Discovery and Planning With Your Developer (3–10 days)

Once you've picked a website development company, the first real project phase is discovery — where the developer maps out pages, features, technical requirements, and a sitemap based on your goals. Expect a kickoff call, a questionnaire or workshop, and a proposed site structure you approve before design begins.

For a simple brochure site, this might be a single call and a one-page sitemap. For a site with custom functionality — a booking system, a customer portal, a product catalog — this phase takes longer because the developer needs to map out data, user flows, and any third-party tools you want connected.

Don't skip this: Rushing discovery to "save time" almost always costs more time later. A missed requirement discovered mid-build usually means reworking pages that were already approved.

Step 3: Design (1–4 weeks depending on complexity)

Design is where wireframes and mockups turn your sitemap into an actual visual layout, and it typically takes 1 to 2 weeks for a template-based site or 2 to 4 weeks for a fully custom design. You'll usually see this in stages: low-detail wireframes first, then full-color mockups of key pages like the homepage and a product or service page.

This is the phase where feedback speed matters most. A developer can typically turn around a revision in a few days — but if your team takes two weeks to review a mockup and gather internal opinions, that delay adds directly to the calendar, not just to "your side" of the project.

Here's a rough comparison of how project size affects the design phase alone:

Site type	Typical design phase	What drives the time
Template/brochure site	3–7 days	Minor customization of an existing theme
Custom business site	2–3 weeks	Original layouts, brand-specific visuals
E-commerce or app-connected site	3–5 weeks	Product pages, checkout flow, account screens

If your site is overdue for a visual overhaul rather than a ground-up rebuild, the process and timeline look a bit different — we cover that distinction in 10 Signs Your Website Needs a Redesign.

Step 4: Development and Content Integration (2–12 weeks)

Development is where the design gets built into a working site, and it's the widest-ranging phase — 1 to 2 weeks for a simple site, 4 to 8 weeks for a mid-size site with a content management system, and 8 to 16+ weeks for e-commerce or custom-built functionality. This phase includes front-end coding (what visitors see), back-end setup (databases, admin panels), and plugging in your actual content — text, images, product listings.

A few things commonly extend development beyond the original estimate:

Content isn't ready — pages get built with placeholder text waiting on real copy.
Integrations with outside tools (payment processors, CRMs, booking software) need extra testing.
New feature requests get added once the client sees the site taking shape.
Image or video assets need to be resized, compressed, or replaced for web use.

If your project also involves a mobile app or plans to connect with one later, it's worth reading how that build sequence works separately, since app timelines follow their own phase structure — we walk through that in The Mobile App Development Process, Step by Step.

Step 5: Testing and Quality Assurance (3–10 days)

Testing checks that the site works correctly across browsers, devices, and screen sizes before it goes live — and it should never be skipped to hit a deadline. This includes checking that forms submit properly, links aren't broken, checkout flows complete on a mobile phone as well as a desktop, and pages load at an acceptable speed.

Site speed specifically deserves attention here, because a slow-loading page affects both visitor experience and how search engines rank the site. According to Google's own PageSpeed guidance, page load time has a direct, measurable relationship to visitor bounce rates. If your site connects to an app or shares a backend with one, performance issues can also ripple into app costs and timelines down the line — a connection we explain in Why Website Performance Affects App Development Costs and Timelines.

For a simple site, testing might take 2 to 3 days. For a site with e-commerce or custom features, budget closer to a week or two, since every integration and payment path needs to be checked manually.

Step 6: Launch and the First Two Weeks After (1–3 days to launch, ongoing after)

Launch itself — pointing your domain to the new site and making it live — usually takes less than a day once everything upstream is approved and tested. The bigger time investment is the week or two right after launch, when you're watching analytics, fixing small issues real visitors uncover, and making sure email, forms, and any tracking codes are firing correctly.

Plan for:

Confirming domain and DNS settings are pointed correctly before the big switch.
Checking that contact forms deliver to the right inbox.
Verifying analytics and any ad-tracking pixels are installed and reporting data.
Testing the site on a few real phones and browsers, not just the ones used during development.
Setting a follow-up check-in at the 2-week and 30-day marks to review performance.

What This Adds Up To, By Project Size

Putting all six phases together, here's what the full timeline looks like end to end:

Project size	Total timeline	Example
Small brochure site	2–4 weeks	5–8 pages, no custom features, template-based
Mid-size business site	6–10 weeks	Custom design, CMS, blog, contact forms
E-commerce or complex site	12–24 weeks	Product catalog, checkout, integrations, custom features

These ranges assume reasonably fast client turnaround on feedback and content. Add several weeks to any of them if content isn't ready when design starts, or if approvals routinely take a week or more to come back.

What to Do Next

If you're planning a new site or a rebuild, the most useful thing you can do before reaching out to any developer is write down your page list, must-have features, and a rough budget — that alone will make your first conversation faster and your quote more accurate. If the project also involves AI-driven features like chatbots or personalized recommendations, it's worth understanding what that adds to scope before you ask for a timeline, which we cover in AI Consulting 101: What Small Businesses Should Know.
