The verdict in three sentences
Migrating from Magento to Shopify B2B costs between 20,000 and 70,000 EUR in 2026, but the decision is made on 3-year TCO, not on the migration price. Shopify Plus (~2,300 EUR/month) removes infrastructure, security updates and much of Magento's technical debt. The migration only makes sense if your B2B features (per-customer pricing, accounts, credit terms) are covered natively or by validated apps.
Migrate to Shopify B2B vs stay on Magento
The e-commerce director rarely compares TCO well: they look at licence price, not full cost. Here is the 2026 order of magnitude over 3 years.
| Item (over 3 years) | Self-hosted Magento | Shopify Plus B2B |
|---|---|---|
| Licence / subscription | Open source | ~82,800 EUR (2,300 EUR/month) |
| Hosting + infra | 18,000 - 45,000 EUR | Included |
| Updates / security | 15,000 - 40,000 EUR | Included |
| Dev maintenance | 30,000 - 70,000 EUR | 10,000 - 25,000 EUR |
| Initial migration | — | 20,000 - 70,000 EUR |
| Technical debt risk | High | Low |
Magento looks "free" to buy but stacks up hosting, security and maintenance. Shopify Plus concentrates cost in a readable subscription, at the price of a less open platform.
What a 45,000 EUR migration covers
| Work package | Share | Watch point |
|---|---|---|
| Catalogue + variants migration | 22% | Data cleanup |
| Customers + B2B price lists | 20% | Per-account pricing |
| B2B functions (accounts, credit) | 20% | Native Shopify B2B or app |
| Design + ERP integration | 23% | Order/stock flows |
| SEO redirects (301) | 8% | Preserve traffic |
| Testing + cutover | 7% | Rollback plan |
SEO redirects (8%) are underestimated: a poorly redirected migration can lose 20-40% of organic traffic for months. The 301 redirect plan is not optional.

Mini case study
Julie, e-commerce director at a B2B distributor in Bordeaux, spends ~4,100 EUR/month on Magento (hosting, security, patches, maintenance), i.e. ~49,000 EUR/year. A 45,000 EUR migration to Shopify Plus brings recurring cost to ~2,300 EUR subscription + ~800 EUR/month maintenance, i.e. ~37,000 EUR/year. The ~12,000 EUR annual saving pays back the migration in ~3.8 years on TCO alone, but lower technical debt and faster time-to-market accelerate the real return well before that.
FAQ
Does Shopify B2B really handle per-customer pricing? Yes, native Shopify B2B handles catalogues and price lists per company. For very fine rules (complex tiers, heavy credit terms), you complement with validated apps or development.
Will I lose my SEO by migrating? Not if the 301 redirect plan is complete and tested before cutover. A botched migration on this point costs traffic; done well, it is neutral or positive thanks to speed.
Is migration worth it for everyone? No: if your Magento is stable and cheap to maintain, stay. Migration is justified when maintenance and security weigh heavily or technical debt blocks your roadmap.
How long does a migration take? Expect 3 to 6 months depending on catalogue size, B2B rule complexity and data quality. Data migration and cleanup are the longest step.
Can we migrate without downtime? Yes, with a planned cutover and a rollback plan. Shopify is prepared in parallel, data is frozen, then you switch over a short, monitored window.
