TL;DR — Updated for 2026 with current pricing, feature parity, B2B and headless capabilities, and the real total cost of ownership over three years — written by a Shopify Plus partner that has run both stacks in production.
The 60-second decision
Where each platform stands in 2026
Shopify Plus in 2026
Shopify shipped more enterprise functionality in 2024–2025 than in any prior two-year window: Checkout Extensibility, B2B on Plus parity with B2C, Markets Pro, Hydrogen + Oxygen, Sidekick AI, native bundles, and PCI-scoped storefronts. The platform has effectively closed the historical gap with Magento on B2B and customization.
Adobe Commerce (Magento) in 2026
Adobe continues to invest in Commerce as part of its Experience Cloud, but the roadmap is dominated by deeper Adobe integration (Sensei, Real-Time CDP, Target) rather than core merchant features. Magento Open Source still exists but receives only security patches; Adobe Commerce on Cloud is now priced largely by GMV, which makes growth feel like a tax.
Real 3-year total cost of ownership
List prices are misleading. The dominant cost on Magento is the team and infrastructure required to keep it shipping. Below is the spread we observe for merchants doing $10–$30M GMV.
Estimated 3-year TCO, mid-market merchant ($10–$30M GMV)
| Cost line | Adobe Commerce | Shopify Plus |
|---|---|---|
| Platform license / fees | $66K–$300K | $72K–$108K |
| Hosting / infrastructure | $60K–$180K | Included |
| Engineering team | $450K–$900K | $120K–$240K |
| Security & PCI | $30K–$90K | Included |
| Apps & integrations | $30K–$60K | $30K–$90K |
| 3-year total | $636K–$1.53M | $252K–$528K |
The savings are not just financial. Shopify Plus teams consistently ship more revenue features per quarter because engineering capacity is freed from infrastructure work.
B2B & wholesale capability
- Customer-specific price lists, NET terms, draft orders, and company hierarchies — native on B2B on Plus, no app required.
- Quote-to-order workflows: parity in 2026 between Shopify Plus and Adobe Commerce; Shopify is shipping faster.
- Punchout / EDI: stronger native ecosystem on Adobe Commerce, but mature partner apps available on Shopify Plus.
- Tax compliance (US sales tax, EU VAT, UK): Shopify Tax + Avalara on Plus; Vertex/Avalara integrations on Adobe.
AI & personalization roadmap
In 2026, AI is no longer a roadmap item — it ships in product. Shopify Sidekick (merchant copilot), Magic (content + image generation), Semantic Search, and recommendation models are bundled into Plus. Adobe leans on Sensei and the broader Experience Cloud, which is powerful but priced as separate licenses and demands enterprise integration work.
Headless & composable commerce
Hydrogen + Oxygen on Shopify Plus give a first-party React framework with managed hosting and edge rendering. Adobe Commerce's PWA Studio is mature but feels like a layer rather than a first-class runtime. For merchants going headless in 2026, Shopify Plus has the lower-friction path; Adobe wins where you need composable commerce wired to Adobe Experience Manager and Target.

Migrating from Magento to Shopify Plus
Most merchants moving off Magento in 2026 are not chasing features — they are escaping operational drag (security patching, hosting, dev capacity tied to upgrades). The migration is well-trodden: customer + order history, product catalog, URL preservation for SEO, integrations rebuild, and a controlled cutover.
Mejix's honest verdict for 2026
If you are between $2M and $50M GMV, do not have a 6+ engineer in-house Magento team, and want to spend the next three years building revenue features instead of patching infrastructure — Shopify Plus is the safer, faster, cheaper choice. If you are >$100M GMV with deep Adobe Experience Cloud commitments and a large in-house team, Adobe Commerce remains defensible.
Frequently asked questions
- Is Magento going away?
- No. Magento Open Source continues with security patches, and Adobe Commerce is actively developed. The trajectory question is whether Adobe's investment matches Shopify's pace of merchant-facing features — in 2024–2026, it has not.
- Can Shopify Plus handle complex B2B?
- Yes. B2B on Plus added customer-specific catalogs, NET terms, company hierarchies, and quote workflows in 2024–2025. We run multiple wholesale stores on Plus today.
- What about SEO during migration?
- Preserved cleanly with a complete 301 map, identical URL slugs where possible, schema parity, and a controlled cutover. We typically see traffic recover in 30–60 days; some clients see net gains because Shopify's Core Web Vitals are stronger out of the box.
- How long does Magento → Shopify Plus take?
- 4–8 months for mid-market with custom integrations. 9–14 months for enterprise B2B with ERP and PIM dependencies. Faster only if catalog is simple and integrations are limited.
- Are Shopify's transaction fees a deal-breaker?
- Plus uses Shopify Payments by default with no platform transaction fee. Third-party gateways add a small percentage; for most merchants this is dwarfed by the savings on infrastructure and engineering.
