How Long Does It Take to Build a Website? A Realistic Timeline

"How long does it take to build a website?" is one of the first questions on almost every discovery call, and it deserves a better answer than "it depends." At Bricksense we have shipped a five-page brochure site in twelve business days and a custom booking platform that took five months from kickoff to launch, and the gap between those two numbers is explained entirely by a handful of concrete factors: page count, whether the design is templated or custom, how many people sign off on each round, and whether the site needs to talk to other systems like payment processors, CRMs, or booking engines. As a rough anchor, most small-to-midsize business websites take 4 to 10 weeks. Ecommerce and anything with custom functionality typically runs 8 to 16 weeks. Full custom web applications with a React or Next.js frontend and a real backend run 3 to 6 months, sometimes longer once scope grows mid-build. The rest of this piece breaks the process into the pieces that actually add up to a launch date, so you can build a timeline for your own project instead of trusting a vendor's landing-page promise of "websites in 5 days."

Start with project type, because "a website" means very different things depending on who is asking. A brochure or marketing site, typically five to twelve pages covering home, about, services, and contact with a blog bolted on, is the fastest category. Built on WordPress, Webflow, or a lightweight custom stack, these run 3 to 5 weeks from signed contract to launch when the client already has copy and images ready, and 6 to 9 weeks when content needs to be written and photographed from scratch. A CMS-driven business site with more structure, multiple service pages, a team directory, case studies, gated resources, sits at 5 to 9 weeks. Ecommerce is its own category: a Shopify store with 20 to 50 products and standard theme customization can launch in 6 to 8 weeks, while a WooCommerce build with custom product configurators, region-based shipping rules, and inventory sync to an existing point-of-sale system stretches to 10 to 14 weeks. Custom web applications, meaning client portals, marketplaces, or SaaS front ends, are measured in months rather than weeks because they involve genuine software architecture decisions, database design, authentication, and QA that a template simply does not require.

Every project, regardless of size, moves through the same five phases, and the time spent in each varies by type. Discovery and scoping comes first: understanding the business, the audience, the competitive landscape, and producing a scope document both sides sign off on. For a brochure site this takes 3 to 5 business days. For a custom application it can run two to three weeks, because you are also locking in technical architecture, choosing a database, and deciding on third-party integrations before a single screen is designed. Skipping or rushing discovery is the single most common reason a project blows its timeline later, because ambiguity in scope does not disappear, it just resurfaces mid-build as scope creep, and by then it costs more in both calendar time and client goodwill to resolve than it would have cost to nail down up front. A good discovery phase ends with a document that lists every page or screen, every third-party integration, who owns final approval, and what "done" looks like, so nobody is negotiating scope in week seven of an eight-week project.

Content collection is the phase clients consistently underestimate, and it is the single biggest source of delay across every project type we have run. Copywriting, photography, product descriptions, team bios, testimonials, legal pages, none of it can be finalized by the agency alone, and waiting on it stalls design and development behind it. A business that assumes it will "send over the content next week" once the contract is signed regularly takes four to six weeks to actually deliver it, because gathering approved copy from five stakeholders and sourcing decent photography is genuinely slow, unglamorous work. The fix that actually works is starting content in parallel with discovery, not after design is approved, and agreeing on a hard content deadline in the contract with a clear consequence, usually that development proceeds on placeholder copy if the deadline slips, rather than the whole project pausing indefinitely. Clients who treat content as homework due in week one consistently finish weeks ahead of clients who treat it as an afterthought, and the difference has nothing to do with the developer's skill.

Design is next: wireframes to establish structure and information hierarchy, followed by high-fidelity mockups that show actual color, type, and imagery. For a template-based site this might be a single round of mockups with one revision cycle, taking a week to ten days. For a custom brand-forward site, expect two to three rounds of revisions and two to four weeks, especially if there are multiple stakeholders with differing opinions on a homepage hero. This is also where a poorly defined approval process costs the most time. If the founder, the marketing director, and an outside brand consultant all need to sign off separately and give conflicting feedback, a two-week design phase can quietly become a six-week one. Naming a single decision-maker before design starts, even if others are consulted, is the cheapest timeline insurance available and costs nothing to implement.

Development is where the actual building happens, translating approved designs into a working, responsive site with real functionality. For a brochure site this typically runs 2 to 4 weeks. For ecommerce, factor in product catalog setup, payment gateway integration, tax and shipping configuration, and testing checkout flows across multiple scenarios, which pushes development to 4 to 8 weeks. Custom applications need backend development, API integrations, and often a staging environment for the client to test against before launch, running 6 to 16 weeks depending on feature count. Development is usually the most predictable phase because it does not depend on external approvals in the same way design does, but it is also where undiscovered scope, a feature nobody scoped clearly in discovery, tends to surface and eat time nobody budgeted.

Quality assurance and testing get compressed or skipped far too often when a timeline is under pressure, and that is a mistake that shows up publicly after launch. Cross-browser testing, mobile responsiveness checks across real device sizes, form submission testing, page speed optimization, and accessibility spot-checks all take real time, typically 3 to 10 business days depending on site complexity. This is also when broken links, missing alt text, and console errors from third-party scripts get caught. A rushed QA phase is how a business ends up with a contact form that silently fails on Safari or a checkout button that does not work on an older Android device, discovered by an actual customer instead of the agency. Building a fixed QA window into the schedule, rather than treating it as flexible padding to absorb earlier delays, protects the launch date and the client's reputation at the same time.

Client review and revision cycles deserve their own honest discussion because they are where good timelines go to die. A single round of "please make the logo bigger" feedback costs a day. A round of feedback that reopens decisions already made in discovery, changing the sitemap after development has started, for instance, can cost a week or more because it ripples through navigation, internal links, and anything already built against the old structure. The projects that stay on schedule are the ones where revision rounds are capped in the contract, typically two to three rounds per phase, and where feedback is collected from one consolidated source rather than trickling in from five people over two weeks. Agencies that build in unlimited revisions as a selling point are, whether they say so or not, building in an open-ended timeline, because there is no natural stopping point without a limit.

Launch itself is rarely instant, and clients are often surprised by this. DNS propagation, the process of the new site becoming visible everywhere on the internet after a domain points to a new server, can take anywhere from a few minutes to 48 hours depending on DNS provider and TTL settings. Migrating an existing site means redirecting old URLs to new ones to preserve search rankings, which takes real planning time if the old site has hundreds of indexed pages. SSL certificate provisioning, email routing checks so that existing company email keeps working after a DNS change, and a final round of smoke testing on the live environment all belong in a launch checklist, not an afterthought done at 5pm on launch day. Building a one-to-two-day buffer around launch, rather than scheduling it for the morning of a client's biggest sales event, has saved more than one project from an unnecessary crisis.

Certain factors reliably extend a timeline beyond its baseline estimate, and it is worth naming them so you can watch for them in your own project. Multiple stakeholders with equal approval authority is the biggest one; every additional person who can say no adds friction, not just time, because feedback often conflicts and has to be reconciled. Integrations with existing systems, a CRM, an ERP, a legacy booking tool, add unpredictable time because you are working against another vendor's API documentation and support responsiveness, not your own team's pace. Custom animations, interactive calculators, or anything that has not been built before by your development team introduces R&D time that is hard to estimate precisely up front. And scope that grows mid-project, "while we're at it, can we also add," is scope creep by another name, and it should trigger a timeline and budget conversation immediately rather than being quietly absorbed.

On the other side, several factors reliably compress a timeline. A single, empowered decision-maker who can approve work without a committee removes the single biggest source of delay outright. Pre-existing brand assets, a real logo file, brand colors, fonts, and photography, mean design starts from a foundation instead of a blank page. A fixed, well-defined scope with no ecommerce, no custom integrations, and a template-based structure lets a team move fast because there are few open technical questions. And content that is ready before development starts, rather than trickling in during it, removes the single most common bottleneck we see across every type of project. None of these are exotic; they are simply discipline, and businesses that apply them consistently finish projects two to three weeks faster than the industry average for the same scope.

To make this concrete, here is a realistic week-by-week timeline for a typical 10-page business website with a moderate custom design, no ecommerce, and one primary approver. Week 1: discovery calls, sitemap, and scope document. Weeks 2 to 3: content collection running in parallel with initial wireframes. Week 4: high-fidelity design mockups delivered, one revision round. Week 5: design approved, development begins. Weeks 6 to 7: development of all pages, CMS setup, mobile responsiveness. Week 8: QA, client review on staging, revision round two. Week 9: final fixes, launch prep, DNS and SSL configuration. Week 10: launch, plus a few days of post-launch monitoring and small fixes. Ten weeks is a comfortable, realistic number for this scope; a lean, highly organized project with fast client turnaround can compress this to 6 to 7 weeks, and a project with a slow-to-respond client or added scope can stretch it to 14 or more.

It is worth distinguishing agency timelines from freelancer timelines and DIY builder timelines, because the honest comparison is not just about speed. A DIY build on Squarespace or Wix can technically go live in a weekend, but the real cost is the owner's own time, usually 20 to 40 hours spread over several weeks once you account for learning the platform, and a result that often looks and performs like a template because it is one. A solo freelancer typically quotes faster turnaround than an agency for the same scope, sometimes 30 to 40 percent faster, but has less capacity to run design and development in parallel and is a single point of failure if they get sick, get busy with another client, or simply underestimate the work. An agency's timeline is usually the most conservative of the three because it accounts for a real QA process, multiple specialists reviewing the work, and project management overhead, and in our experience that conservatism is exactly what prevents the embarrassing post-launch surprises that DIY and solo-freelancer projects run into more often.

If you genuinely need a site fast, the honest move is not to demand a compressed version of the full scope, it is to shrink the scope itself and phase the rest. A minimum viable version of most business sites, homepage, one services page, contact page, and a placeholder for everything else, can realistically launch in 10 to 14 business days if content is ready on day one and there is a single decision-maker. The remaining pages, blog, detailed case studies, additional service pages, then launch in a second phase over the following month without holding up the business's ability to be found online and take inquiries. This phased approach beats rushing the full scope, because a rushed full build under time pressure is where corners get cut on QA, accessibility, and mobile testing, and those corners tend to surface as real problems within the first few weeks of traffic.

A useful habit that keeps timelines honest is building an explicit buffer into the schedule rather than quoting the optimistic best case and hoping nothing goes wrong. We typically add 10 to 15 percent contingency time to any quoted timeline, not disclosed as "padding" but built into specific phases most likely to slip, usually content collection and revision rounds, since those are the two phases most dependent on people outside the development team. A ten-week project quoted with an internal eleven-and-a-half-week cushion rarely needs all of it, but when a client's marketing director goes on leave mid-project or a stakeholder takes an extra week to approve a homepage design, the buffer absorbs the slip without pushing the actual launch date, which is far better for the relationship than renegotiating the deadline every time something minor goes sideways. Clients rarely object to a slightly more conservative number when it is explained this way, because a date that reliably holds is worth more than a slightly earlier date that reliably slips.

Communication cadence during the build matters almost as much as the schedule itself, because a client left in the dark for two weeks between milestones tends to assume the worst regardless of whether anything is actually wrong. A weekly or biweekly short status update, even a two-line email noting what was completed and what is coming next, keeps a project psychologically on track and gives the client a natural, low-pressure opportunity to flag a concern before it becomes a bigger delay. Projects that go quiet for long stretches are also the ones where a client's own delay, an unanswered question about a feature, unapproved copy sitting in an inbox, goes unnoticed by the agency until it has already cost a week, simply because nobody was checking in regularly enough to catch it early. A five-minute weekly update is cheap insurance against exactly this kind of silent, avoidable slippage.

A properly detailed schedule should also specify what happens on the client's side of each milestone, not just the agency's, because a one-sided schedule quietly assumes the client will always be ready exactly on time, which experience says is the exception rather than the rule. Naming specific client deliverables, final copy for all pages by a specific date, brand assets and logo files by a specific date, a single consolidated round of feedback by a specific date, and attaching a consequence to each, typically that the following phase proceeds using placeholder content or the previous round's design if the deadline passes without input, keeps the schedule a two-way commitment instead of a one-way promise the agency alone is accountable for. This single change in how a schedule is written accounts for a meaningful share of the difference between projects that launch on the quoted date and those that quietly slip by three or four weeks.

Launch is also not really the end of the timeline conversation, even though it is often treated as the finish line in a project plan. The first two to four weeks after launch typically involve a round of real-world bug fixes as actual visitors, on real devices and real browsers, use the site in ways internal QA did not anticipate, plus early performance and analytics review to confirm the site is actually being found, indexed, and used the way it was designed to be. Building this post-launch window explicitly into the project timeline, rather than treating launch as the final deliverable with everything after it billed ad hoc and unplanned, sets a more accurate expectation for when a project is genuinely, fully complete, and it is the difference between a client who feels supported through the first month of a new site's life and one who feels abandoned the moment the invoice is paid.

It is also worth naming the specific project management habits that separate agencies who consistently hit their quoted dates from those who consistently slip by two to four weeks on similar-scope work, because the difference is rarely raw skill and much more often process discipline. Teams that hit dates reliably tend to run a short weekly internal check-in specifically reviewing what is at risk of slipping before it actually does, rather than only discovering a delay when a milestone date has already passed. They also tend to separate "waiting on client" time from "actively working" time explicitly in how they track a project, so that a two-week delay caused by a client sitting on a design approval is visibly attributed to that cause rather than quietly blending into the overall timeline and eroding the vendor's own credibility for a delay that was not actually theirs. For a business hiring an agency or freelancer, it is entirely reasonable to ask, before signing anything, how they track progress internally and how they will flag a slipping milestone early rather than only at the deadline itself, since the answer to that question predicts the accuracy of the very timeline you are about to agree to.

The single highest-leverage thing a business can do to keep a website timeline honest is to ask for a phase-by-phase schedule with named deliverables and named owners before signing anything, not just a total number of weeks. "8 weeks" as a single figure hides where the risk lives; "content due end of week 2, design approved by week 4, development complete week 7, QA and launch week 8" tells you exactly where things can slip and lets you catch it early rather than discovering in week 7 that content was never finalized. At Bricksense we build every proposal this way specifically because it turns a vague promise into a shared, checkable plan, and it is the difference between a client who trusts the timeline and one who is anxiously refreshing their inbox every Friday wondering if launch is still on track.
