What a Magento to Shopify Migration Actually Costs

There's no single number that applies to every Magento to Shopify migration — cost depends heavily on catalog size, how many custom features need to be rebuilt, and whether you're moving to standard Shopify or Shopify Plus. But most brands considering this move want a realistic range before they start requesting quotes, so here's a grounded breakdown.

The Main Cost Drivers

Catalog size and complexity

A few hundred simple products costs far less to migrate than tens of thousands of SKUs with complex variant structures, custom attributes, or configurable products (a Magento-specific concept that doesn't map directly onto Shopify's variant system and often needs custom logic to replicate).

Custom Magento functionality

Magento's flexibility means many stores have accumulated custom modules over the years — bespoke checkout logic, custom pricing rules, unique B2B functionality. Every one of these needs to be identified, evaluated (is there a Shopify-native way to do this now?), and either rebuilt or replaced. This is usually the single biggest cost variable, and it's also the part most commonly underestimated by merchants requesting a quote before an agency has actually audited their store.

Data volume and history

Customer records, order history, and product reviews all need to move cleanly. More historical data generally means more validation work, though this scales less dramatically than catalog complexity.

Design: theme vs. fully custom

Adapting an existing Shopify theme costs meaningfully less than a fully custom design built from scratch. Many migrations use this as an opportunity to modernize design, which adds cost but often pays for itself in conversion rate.

Shopify Plus vs. standard Shopify

Shopify Plus unlocks checkout customization, Shopify Functions, and higher API rate limits — all of which matter for stores with complex B2B pricing or high-volume custom logic. It's also a different cost tier for the platform itself, separate from migration labor.

Rough Ranges (and Why They're Rough)

For context, general Shopify website builds in 2025-2026 tend to range from a few thousand dollars for a simple store on an existing theme, up to $50,000+ for complex, fully custom Shopify Plus builds. A Magento migration specifically tends to sit on the higher end of that range relative to a from-scratch build, because of the additional discovery and data-mapping work a migration requires that a greenfield build doesn't.

Any agency giving you an exact number before auditing your specific store and its custom functionality is guessing. The responsible way to get an accurate figure is a scoped discovery phase — typically a paid or lightly-scoped audit — that inventories your actual Magento setup before committing to a fixed price.

Where Merchants Commonly Overpay or Underbudget

Underestimating custom functionality audit time. Skipping a proper discovery phase leads to scope creep once hidden custom logic surfaces mid-project.
Ignoring SEO redirect work as a line item. Redirect mapping for a large, established Magento store is real, billable work — not a checkbox an agency should be doing for free at the last minute.
Comparing quotes without comparing scope. A low quote that excludes data validation, QA, and post-launch support isn't actually cheaper — it's the same work, deferred and unbudgeted.

Getting an Accurate Quote

The only way to get a number that means anything is a scoped audit of your actual store — your catalog, your custom modules, your integrations, and your data volume. TheGenieLab has migrated stores off Magento (including Cosabella and Out-Grow) to Shopify Plus, and starts every migration engagement with exactly this kind of audit before quoting a fixed price.

Frequently Asked Questions

Is migrating from Magento to Shopify cheaper than staying on Magento?

Often, yes, over time — Magento requires ongoing hosting, security patching, and developer maintenance that Shopify's hosted model eliminates. But the migration itself is an upfront cost that needs to be weighed against those ongoing savings.

Does migrating to Shopify Plus cost more than standard Shopify?

Yes, both in platform subscription cost and often in build complexity, since Shopify Plus stores tend to have the more complex custom logic that justifies the upgrade in the first place.

How long does a typical Magento to Shopify migration take?

Most take 6–12 weeks from kickoff to go-live, though catalogs with extensive custom functionality can run longer.
