Shopify Plus Migration Cost Calculator

Most agencies answer “it depends” and book a call. Tell us what you’re running now — catalogue size, apps, integrations, custom work — and get a real Shopify Plus migration cost range in about a minute, with the breakdown so you can see how the number was built.

What actually drives the cost

Migration quotes vary enormously because the work varies enormously. Six things move the number more than anything else:

  • What you’re coming from. Shopify to Plus keeps your data model, so it is largely a re-platform. Magento or a custom build is closer to a rewrite.
  • Catalogue size. Variant mapping, metafields and the QA surface all scale with SKU count.
  • Design. Carrying the current theme over, refreshing it, or rebuilding are three very different budgets.
  • Your app estate. Every app is a decision: port it, replace it, or drop it because Plus does it natively.
  • Integrations. ERP, PIM, 3PL and subscription systems are usually the single largest line after the base build.
  • Custom requirements. B2B, multi-store, headless and checkout extensibility each add real engineering.

What the estimate includes

  • Theme and design carry-over, or a rebuild if that’s cheaper
  • App migration, and replatforming anything Plus supersedes
  • Custom development: B2B, wholesale, headless, integrations
  • Data migration, device-matrix QA, and an SEO-safe cutover with a rollback plan
  • A 30-day post-launch support window

Shopify Plus platform fees are billed by Shopify and are quoted separately — never folded into build cost. It is Shopify’s revenue, not ours, and merchants who see them merged reasonably assume a markup.

Why it’s a range, not a number

Any figure presented as exact before discovery is a figure someone has to walk back later. The calculator returns a band, a delivery window, and the assumptions the estimate rests on — because the assumptions are what decide whether a quote survives contact with the project.

Fixed scope, fixed price. Once scope is agreed at kickoff, the estimate is the estimate.

Frequently asked questions

How much does a Shopify Plus migration actually cost?

It depends on catalogue size, app count and how much custom work carries over — which is exactly why we built a calculator instead of writing “it depends”. Give it a minute and you’ll get a real range. Shopify’s platform fee sits on top and is separate from build cost.

How long does a migration take?

The calculator returns a delivery window alongside the cost. A straightforward Shopify to Plus move is typically a matter of weeks; a Magento migration with ERP and headless work runs considerably longer. Accelerating a plan costs money, because it costs parallelism.

Will I lose my search rankings?

Not if the cutover is handled properly. Redirect mapping and an SEO-safe cutover with a rollback plan are included in every estimate rather than sold as an extra — it is the part most likely to cost you money if it is skipped.

Is the estimate binding?

No. It is an informed range based on what you told us, and it states its own assumptions. A binding fixed-scope proposal comes after discovery, when we have seen the actual store.
