The verdict in three sentences
A Magento to headless migration in New York runs between 50,000 and 130,000 EUR in 2026, including catalogue and order migration. The real argument isn't the project cost but the 3-year TCO: licences, heavy hosting and Magento maintenance often weigh more than the rebuild itself. The payoff: green Core Web Vitals and a measurable conversion lift that funds the migration.
Why leave Magento in 2026
Magento (Adobe Commerce) is still powerful but heavy: demanding hosting, costly version upgrades, scarce and expensive specialised maintenance, penalising mobile load times. A headless stack (Next.js on the front, Medusa or commercetools on the back) decouples storefront and commerce: the front becomes fast and flexible, the back focuses on catalogue, pricing and orders.
- Catalogue migration: products, variants, attributes, media, B2B price lists.
- Order/customer migration: history, accounts, credit terms.
- Front rebuild: performance, technical SEO, B2B UX.
- Integrations: ERP, PIM, payment, carriers.
- 301 redirects: preserve existing SEO.
| Migration item | 2026 range (EUR) |
|---|---|
| Scoping & architecture | 6,000-12,000 |
| Headless front (Next.js) | 20,000-45,000 |
| Commerce back (Medusa/commercetools) | 15,000-40,000 |
| Data migration | 5,000-15,000 |
| Integrations (ERP, payment, PIM) | 8,000-25,000 |
| Testing, SEO, go-live | 6,000-15,000 |
| Project total | 50,000-130,000 |
Magento vs headless TCO over 3 years
A Magento's cost doesn't stop at the licence: dedicated hosting, security, upgrades and maintenance pile up. Here is the 2026 order of magnitude for a mid-sized B2B site.
| Item (over 3 years) | Magento (Adobe Commerce) | Custom headless |
|---|---|---|
| Licence / platform | 22,000-60,000 EUR | 0 (open source) |
| Hosting | 900-2,500 EUR/month | 300-800 EUR/month |
| Maintenance / evolutions | 2,500-6,000 EUR/month | 1,500-3,500 EUR/month |
| Version upgrades | 15,000-40,000 EUR | Incremental |
| 3-year total (order of magnitude) | 180,000-320,000 EUR | 110,000-190,000 EUR |
On top of that comes the conversion lift: going from a 4.2s LCP to 1.8s often improves conversion by 10 to 20%, which weighs heavily on B2B revenue.
Mini case study
Sophie, e-commerce manager at a B2B distributor in New York (online revenue 6M EUR/year), runs a Magento at 2,100 EUR/month hosting and 4,500 EUR/month maintenance, plus a 30,000 EUR upgrade every 18 months.
She migrates to headless for 95,000 EUR. New costs: 600 EUR hosting + 2,800 EUR maintenance per month. Recurring saving: (6,600 - 3,400) = 3,200 EUR/month, or 38,400 EUR/year, before upgrades. On conversion, a +12% lift on 6M EUR represents ~720,000 EUR of additional revenue/year at improved margin. The migration pays back in under 12 months.
