One of the first questions businesses ask when planning a new ecommerce website is how long the project will take. The honest answer is that it depends — on the platform, the complexity of the build, the number of products and how prepared your business is before the project starts.
This guide gives you realistic timelines for each major platform, explains what affects the schedule and helps you plan your project with confidence.
Is This the Right Platform for Your Timeline?
Before planning timelines it's worth confirming you're evaluating the right platform. If speed of launch is your primary objective, some platforms are significantly faster than others — and choosing the wrong one at the start can add months to your go-live date.

What Affects the Build Timeline?
Several factors influence how long an ecommerce website takes to build. Understanding these before you brief an agency helps you set realistic expectations and avoid common delays.
Platform Choice
No single decision has a greater impact on your project timeline than the platform you choose. Wix and Shopify are significantly faster to launch than WordPress or Magento. A Wix website can be live in two to four weeks. A complex Magento build can take six months or more.
Number of Products
Setting up, importing and configuring products takes time — particularly if variants, images, descriptions and pricing need to be prepared or migrated from an existing system. A store with 20 products takes considerably less time to set up than one with 2,000.
Custom Design vs Theme
A professionally customised theme is faster to deliver than a fully bespoke design built from scratch. Bespoke design involves discovery, wireframing, design concepts, revisions and sign-off before development begins — adding two to four weeks to the timeline.
Integrations
Connecting your website to third-party systems — ERP, CRM, warehouse software, payment gateways or marketing platforms — adds complexity and time. Each integration requires scoping, development, testing and sign-off, often adding two to eight weeks depending on the systems involved.
Content Readiness
One of the most common causes of project delays is content that isn't ready when the build starts. If product descriptions, images, copy and brand assets aren't prepared in advance, the project stalls while waiting for content. Preparing content before the build begins is one of the most effective ways to keep a project on schedule.
Client Feedback and Approvals
Projects move at the speed of feedback. Timely responses to design concepts, development queries and sign-off requests keep a project on schedule. Delayed feedback is one of the most common reasons ecommerce projects overrun their original timeline.
Migrations
If you're moving from an existing platform, data migration — products, customers, orders, URLs and SEO redirects — adds time to the project. The volume of data and the complexity of the source platform both influence how long migration takes.
Typical Build Timelines by Platform
The following timelines are realistic estimates for professionally built ecommerce websites. They assume content is prepared, feedback is timely and the scope is clearly defined at the outset.
Wix — 2 to 6 Weeks
Wix is typically the fastest platform to launch. A professionally designed ecommerce website can often be completed within two to six weeks, making it an excellent choice for businesses that need a professional online presence quickly.
Projects move towards the upper end of that range when bespoke design, larger product catalogues or additional functionality—such as bookings, memberships or multilingual content—is required.
Shopify — 4 to 10 Weeks
A theme-based Shopify store typically launches within four to six weeks. Bespoke Shopify projects generally take eight to ten weeks, while Shopify Plus implementations involving custom checkout development or complex integrations may require additional time depending on scope.
WordPress — 6 to 14 Weeks
Most WordPress websites are completed within six to ten weeks, while WooCommerce projects with bespoke design and integrations typically take ten to fourteen weeks. The platform's flexibility allows highly tailored solutions but usually results in longer implementation times than Shopify or Wix.
Magento — 10 to 24 Weeks
Magento projects require the longest implementation period. Magento Open Source websites typically take ten to sixteen weeks, while complex Adobe Commerce projects with bespoke functionality, enterprise integrations and large catalogues often require twenty to twenty-four weeks or more.
The additional planning and development time reflects the platform's flexibility and enterprise capabilities rather than inefficiency.
How to Keep Your Project on Schedule
Regardless of which platform you choose, the following steps will help keep your project on track:
Prepare all content — copy, images, product descriptions and brand assets — before the build starts
Agree a clear project scope and brief with your agency before work begins
Respond to design concepts, development queries and approval requests promptly
Assign a single internal point of contact to manage the project on your side
Avoid scope changes during the build — new requirements mid-project are the most common cause of timeline overruns
Allow time for testing before launch — rushing the testing phase leads to post-launch issues
Discovery and Planning — Why It Matters
A well run ecommerce project begins with a thorough discovery and planning phase before any design or development work starts. This typically takes one to two weeks and involves understanding your business objectives, mapping the customer journey, defining the scope and agreeing the project plan.
Businesses that skip or rush discovery often face scope changes, miscommunication and delays during the build. The time invested at the start of a project almost always saves more time later.
At Venice every project begins with a detailed conversation about your business — your goals, your customers, your operations and your growth plans — before we make a single recommendation or write a single line of code.
Our View
If speed of launch is your primary objective, Wix or Shopify are the right platforms. Both can deliver a professional, conversion-focused ecommerce website within four to ten weeks — without requiring a large development budget or technical team.
If your requirements are more complex — large catalogues, bespoke functionality, B2B operations or deep integrations — WordPress or Magento will serve you better in the long term, even though the build takes longer. Choosing a platform because it's faster to launch—rather than because it's right for your business—often leads to greater cost and disruption later.
The right timeline is the one that delivers a website built correctly for your business — not simply the fastest one available.
