MedusaJS + Next.js: B2B storefronts that stay aligned with ERP
Headless B2B separates presentation (Next.js) from order and catalogue engines (e.g. MedusaJS) so ERP changes do not force a storefront rewrite.
Why Medusa is often a strong B2B core
B2B projects repeat contract assortments, volume tiers and customer-system integrations. Medusa offers an extensible data model and hooks to attach rules without fighting a shop monolith.
Early boundary definition matters: what is a “product” in Medusa versus what stays in ERP and is only synchronised.
Next.js: performance, SEO and role-specific paths
A Next.js storefront enables SSR/SSG where indexability matters and dynamic dashboards for sales and buyers.
We ship a shared design system and lazy-loaded modules so first paint on LTE does not kill conversion.
API contracts and event queues
ERP integrations fail with timeouts and retries, so we use queues and idempotent endpoints. A late webhook does not corrupt stock state.
We document OpenAPI contracts and failure scenarios before the first integration sprint.
Frequently asked questions
- Will Medusa replace the whole ERP?
- No. Medusa covers the commerce and online order layer. Finance, manufacturing and full logistics stay where they are, with controlled sync.
- How long is a typical headless B2B MVP?
- It depends on integrations and pricing complexity, often 8–16 weeks to first production traffic with a tight scope.
- Is Next.js mandatory?
- No. it is our common choice for SEO and full-stack teams. Other fronts work with a solid API model and observability.
