What a Shopify Plus rebuild is, and when it beats another patch
A Shopify Plus rebuild is a ground-up reconstruction of an existing store: a new storefront, a clean data model, and rebuilt integrations, with your catalog, customers, order history and URL structure carried across intact. It is not a redesign. A redesign changes how the store looks. A rebuild changes what it is made of.
Most high-volume stores don't fail suddenly. They accumulate. Five years of theme edits from four different developers. Forty apps, half of them injecting scripts nobody can trace. A checkout that converts a little worse every quarter, and no one knows which change did it.
The usual signals a rebuild is due:
- Conversion dropped after a theme change and never recovered. The cause is buried under years of overrides.
- Page speed tanks on high-traffic days. Your store is fast at 2pm on a Tuesday and slow during your biggest sale.
- App conflicts. Every new install risks breaking two old ones.
- Integrations hitting Shopify API rate limits, queueing orders and syncing inventory late.
- Your developers spend more time working around the build than building.
If three of those sound familiar, patching now costs more than rebuilding. We can show you that maths in a discovery and strategy engagement before you commit to anything.
Our team leads the rebuild, from the first audit to testing and launch. AI helps us investigate the existing code, develop changes and test faster. We decide what to keep, what to replace and how to check that it works.
How we rebuild without breaking your store
The rebuild runs in parallel. Your live store keeps trading while we build its replacement next to it. Cutover happens when everything is tested, not when a deadline says so.
- Audit. We map your current build: theme code, apps, integrations, data model, URL structure, and traffic. Everything that earns you money gets documented before anything gets touched.
- Scoped Phase 1. The core rebuild is scoped and agreed before we start. No hourly meter.
- Build. Complex catalogs, heavy content, and international storefronts go headless on Hydrogen with Sanity and Algolia. Simpler catalogs stay on Online Store 2.0, properly built. We recommend the cheaper option when it's the right one.
- Cutover. Zero downtime. Every URL mapped and 301'd, structured data carried over, rankings protected the same way we run platform migrations. If you're moving up from standard Shopify at the same time, that's a Shopify to Shopify Plus upgrade and we fold it into the same build.
- Roadmap. Post-launch work runs as weekly sprints through support and optimisation. You control the menu.

Built for customers, Google and AI search
A rebuild is a chance to improve how customers find products and how search engines understand the store. We plan navigation, product data, buying content and structured data as part of the build.
Shopify AEO work helps make product details and buying answers easier for Google and AI search to understand. For a diagnosis first, start with an AI visibility assessment.
Our designers use your customer and store data to guide UI and UX decisions. After launch, Run provides ongoing improvements and support.
What a rebuild costs
Phase 1 is scoped and confirmed after discovery. No hourly meter, no scope surprises. For a realistic ballpark on build cost and timeline, run the Shopify Plus migration calculator; rebuilds scope the same way. Platform fees are separate, and the pricing calculator covers those in two minutes.
Post-launch, roadmap items are scoped in sprint durations through a monthly retainer. A month always costs what you agreed, not what accumulated.

Frequently Asked Questions
What is a Shopify Plus rebuild?
A Shopify Plus rebuild is a ground-up reconstruction of an existing store: new storefront, clean data model, rebuilt integrations, with catalog, customers, order history and URL structure carried across. A redesign changes how a store looks. A rebuild changes what it is made of. Brands rebuild when years of theme edits, app conflicts and integration workarounds cost more to patch than to replace.
How long does a Shopify Plus rebuild take?
Typically 10 to 16 weeks for a high-volume store, depending on catalog complexity and integrations. The store trades normally the whole time because the rebuild runs in parallel.
Will we lose rankings during the rebuild?
No. Every URL is mapped before cutover, redirects are 301s, and structured data carries over. It's the same ranking-protection process we use on platform migrations, where preserving SEO equity is the whole job.
Should we rebuild headless or on a theme?
Depends on your catalog and team. Complex catalog, heavy content, international storefronts: headless on Hydrogen with Sanity and Algolia. Simpler catalog, lean team: Online Store 2.0 theme, properly built. Headless costs more and needs engineering ownership. We'll recommend the cheaper option when it's the right one.
How do you handle Shopify API rate limits on high-volume stores?
Bulk operations for large data jobs, queued writes with backoff for integrations, and webhook-driven syncs instead of polling. Rate limits are an architecture problem, and a rebuild is when you fix the architecture.
Can you rebuild while our store stays live?
Yes. Parallel build, staged testing, zero-downtime cutover. Your customers never see a maintenance page.
What does a Shopify Plus rebuild cost?
Phase 1 is scoped and agreed after discovery. The migration calculator gives a realistic ballpark for build cost and timeline. Ongoing roadmap work is priced in sprint durations through a retainer, so costs stay predictable.
