Launching a Shopify Plus store typically takes between 8 to 16 weeks, though the exact timeline can vary based on multiple factors such as store size, design complexity, and development needs.
1. Discovery & Planning (1–2 Weeks)
This phase includes understanding your business goals, audience, product catalog, and feature requirements. Agencies also gather assets like logos, brand guidelines, and initial content.
2. Design & Branding (2–4 Weeks)
Custom design work begins here—either from scratch or based on a chosen theme. It includes UX/UI design, wireframes, branding integration, and user flow planning.
3. Development & Integration (3–6 Weeks)
The Shopify Plus store is developed and customized. This phase includes building custom features, integrating third-party apps, setting up payment/shipping, and configuring the backend.
4. Testing & Quality Assurance (1–2 Weeks)
Rigorous testing ensures the site works smoothly across devices and browsers. Checkout, product pages, and integrations are reviewed for performance and security.
5. Launch Preparation & Go Live (1 Week)
Final revisions are made, content is uploaded, SEO basics are applied, and the store is launched.
🕒 Note: Timelines may extend if there are delays in content delivery, frequent revisions, or complex third-party integrations. Working with an experienced Shopify Plus agency can help streamline the process.
