Magento vs Shopify vs Jumpseller para o mercado português, qual escolher?

Three real options for Portuguese merchants, three different ceilings:

• Jumpseller, Portuguese-founded (Lisbon, 2009), strongest for €50k, €500k Portuguese DTC. MB WAY + Multibanco + SIBS Pay built-in. SAFT-PT auto-export. Limits hit fast on B2B, multi-store, custom catalogues, or PT + BR multi-region.
• Shopify, great for early-stage DTC fashion / cork / Port wine direct sales. Portuguese MB WAY support is via 3rd-party apps (not native), and SAFT-PT e-Fatura needs a paid app (Sufio, Quaderno). Subscription fees + transaction fees stack up, Shopify Plus runs €2k+/mo + 0.15-0.6% on top.
• Magento 2 (Adobe Commerce), the right choice when you need full MB WAY native, SIBS Pay direct, SAFT-PT pipeline owned by you, Multibanco references, B2B with NIF + Net-30, multi-store PT + ES + BR, or ERP integration (Primavera, Sage, PHC, SAP). Higher upfront, much lower long-term TCO.

Typical migration trigger from Jumpseller / Shopify: hitting MB WAY-native limits, Brazilian Lusophone cross-border, or B2B contract requirements.
