Shoptet and Shopify are great for 80% of e-shops. For the remaining 20% they're too small — they need custom discount logic, a unique B2B workflow, integration into existing systems (SAP, Dynamics) or simply don't want to depend on a platform that raises its prices every year.
A custom e-shop in Next.js + React means: no monthly platform fees (Shopify takes 2.9% of every turnover), 100% your own code, any architecture, any integration. You host wherever you want, you change whatever you want, and if we end the collaboration, you get the full source code.
Stack: Next.js 15 + React 19 on the frontend, PostgreSQL / Supabase on the backend, Stripe / GoPay / Comgate for payments, modern cloud infrastructure for hosting. Tested enterprise-grade components, not experimental frameworks.
