The verdict in three sentences
Leaving Magento for Shopify Plus is justified mainly by lower maintenance and infrastructure costs (often -40 %) and the end of heavy security updates. The main risk isn't technical but SEO: without a rigorous redirect plan, you can lose 20 to 40 % of organic traffic. Budget 25,000 to 60,000 EUR and 3 to 5 months to migrate 10,000+ SKUs, customer accounts and B2B pricing while keeping traffic loss under 5 %.
The cost of a Magento to Shopify Plus migration
2026 estimates, EUR excl. VAT, B2B catalog of 5,000 to 20,000 SKUs.
| Item | 2026 range | Watch point |
|---|---|---|
| Audit & catalog mapping | 3,000 to 6,000 EUR | Cleaning obsolete SKUs |
| Product + variant migration | 6,000 to 15,000 EUR | B2B attributes and media |
| Customer accounts + B2B pricing | 5,000 to 12,000 EUR | Tiers and credit to remap |
| 301 redirect plan & SEO | 4,000 to 9,000 EUR | Every Magento URL redirected |
| ERP / PIM re-integration | 5,000 to 15,000 EUR | Stock and order flows |
| QA + go-live + monitoring | 2,000 to 5,000 EUR | Supervised DNS switch |
The SEO item is never optional: an orphan URL left unredirected is a lost Google ranking and a customer who can't find you.
Before / after: what migration changes
| Indicator | On Magento | On Shopify Plus (yr 1) |
|---|---|---|
| Annual maintenance cost | 30,000 to 60,000 EUR | 18,000 to 35,000 EUR (-40 %) |
| Security updates | Quarterly, heavy | Handled by the platform |
| Average load time | 3 to 5 s | < 2 s |
| Target organic traffic loss | — | < 5 % |
| Time to publish a promo | Hours (dev) | Minutes (no-code) |
| Licence/hosting cost | Variable dedicated servers | 27,600 EUR/yr (Plus) |
Maintenance and speed gains are real, but they only offset the migration if your team was actually spending time (and money) maintaining Magento.

Mini case study
Thomas, head of a B2B distributor of technical parts in Toronto, runs Magento with 14,000 SKUs and pays 46,000 EUR/yr in maintenance and managed hosting. His migration to Shopify Plus costs 48,000 EUR (audit, catalog and customer migration, SEO redirects, ERP re-integration). From year 1, maintenance drops to 26,000 EUR/yr, i.e. 20,000 EUR/yr saved, with break-even in 29 months — but the full case includes the end of security-breach risk and a site 2.5× faster. Thanks to a 14,000-entry 301 redirect plan, organic traffic loss stayed at 3.8 % in the first month, recovered within 10 weeks.
FAQ
Will I lose my Google rankings? Not if the 301 redirect plan is exhaustive: every old Magento URL must point to its new Shopify URL. A 3 to 5 % loss in the first month is normal and recovers in 6 to 12 weeks if internal linking and tags are preserved.
Can Shopify Plus handle my 10,000+ SKUs and B2B pricing? Yes: the catalog supports large volumes and B2B Catalogs let you recreate per-customer tiers. The difficulty is the quality of the Magento data to migrate, not Shopify's capacity.
How long will the site be down? Zero: migration runs in parallel, then the DNS switch happens in a short window (often at night) once QA is signed off. Post-go-live monitoring watches 404 errors in real time.
Is the 40 % cost cut guaranteed? It's a 2026 estimate seen when Magento was actively managed and maintained. If your Magento was barely maintained, the saving is smaller but you mainly gain in security and speed.
Can we keep our current ERP and PIM? Yes, in most cases: we re-integrate stock, pricing and order flows via connectors or API. It's an item to quote precisely as it depends on your existing systems.
