The verdict in three sentences
A Magento migration to a B2B platform costs between EUR 25,000 and 70,000 depending on data volume and number of integrations. Magento's maintenance cost (security updates, heavy hosting, scarce developers) is often what triggers the project: EUR 1,500 to 4,000/month you can save. Risk is controlled through rigorous data migration and a complete SEO redirect plan.
Why leave Magento in 2026
Magento is still powerful but heavy: demanding hosting, frequent security updates and high cost of ownership for a B2B SME. Compare Magento to a modern target on the items that weigh most.
| Criterion | Magento (current) | Modern B2B target |
|---|---|---|
| Monthly hosting | EUR 400-1,200 | EUR 150-500 |
| Maintenance / security | EUR 1,000-2,500/mo | EUR 400-900/mo |
| Cost of an enhancement | High (specialists) | Moderate |
| Mobile performance | Variable | Optimised |
| Ecosystem dependency | Strong | Weak |
| Native B2B functions | Paid extensions | Built in |
Over three years, the TCO gap frequently covers the cost of the migration itself.
The line items of a B2B migration
Migration isn't a redesign: 60% of effort is in data migration and redirects. Ballpark 2026 figures, EUR. Timeline 4-8 months.
| Line item | 2026 range | Watch point |
|---|---|---|
| Catalogue and variant migration | EUR 5,000-12,000 | Attributes, media |
| Customer and price-grid migration | EUR 4,000-10,000 | Negotiated prices |
| Order history migration | EUR 3,000-8,000 | Open credit |
| SEO 301 redirects | EUR 3,000-7,000 | URL mapping |
| ERP integration | EUR 6,000-18,000 | Reconnecting flows |
| Testing and cutover | EUR 4,000-9,000 | Rollback plan |
| Migration total | EUR 25,000-70,000 | Cutover window |
Redirects are the most underestimated item: done poorly, they drop organic traffic 20-40% for months.

Mini case study
David, owner of a B2B industrial-parts merchant in New York, pays EUR 3,200/month across Magento hosting and maintenance. His migration to a modern platform costs EUR 52,000. The new infrastructure runs at EUR 1,100/month, i.e. EUR 2,100/month saved, so EUR 25,200/year. Added to fewer incidents and better mobile conversion, the project pays back in about 22 months, then generates recurring savings.
FAQ
What does a Magento-to-B2B migration cost? Between EUR 25,000 and 70,000 depending on data volume, ERP integrations and the number of URLs to redirect. Data migration is most of the effort.
Will we lose our SEO? Not if the 301 redirect plan is complete and tested before cutover. An exhaustive URL map avoids the traffic drop; it's a EUR 3,000-7,000 item not to skimp on.
How long does a migration take? Expect 4-8 months depending on complexity. Final cutover happens over a short window with a rollback plan to stay safe.
What maintenance savings to expect? Often EUR 1,500-4,000/month between lighter hosting and reduced maintenance. Over 3 years, that usually covers the migration cost.
Can we migrate in stages? Yes: you can move catalogue and orders first, then ERP and advanced functions. That reduces risk but slightly lengthens the schedule.
