MedusaJS 2.0 - Scalable e-commerce for ambitious brands
Full control over sales processes, B2B and international expansion in 2026
MedusaJS 2.0 is not just technology - it’s a ready-made foundation for your unique business model. It combines the benefits of ready-made platforms (OMS, Multi-region, Promotions) with the flexibility of custom software. Ideal for companies that have outgrown templates and need a system adapted to their processes, not the other way around.
Ready-made processes you don't have to invent from scratch
MedusaJS is not just code - it's a complete e-commerce engine with built-in support for key business processes.
Advanced OMS
Native support for returns, exchanges (swaps), and claims. Your staff handles everything from one panel, and customers have full visibility into status.
Global Sales (Cross-border)
Sell in multiple markets from a single instance. Different currencies, VAT rates, shipping methods, and price lists assigned to regions.
B2B & B2C Hybrid
Serve retail and wholesale customers in one system. Customer groups, dedicated Price Lists, and individual discounts.
Promotion Engine
Create complex campaigns: "Buy X, get Y", free shipping threshold, discount codes with usage limits and rules.
Service
Headless & B2B commerce
Full offering: B2B/B2C, integrations, storefronts — MedusaJS is one pillar, not the whole service.

When MedusaJS 2.0 is the best business decision
Choose Medusa if your e-commerce is more than a simple online store and you need a tool that won’t limit you.
- You plan expansion into multiple markets (Multi-region, different currencies and taxes in one panel)
- You need an advanced B2B model (price lists per client, deferred payments, credit limits)
- Your logistics and warehouse processes (OMS) require custom integrations (ERP, WMS)
- You want to avoid high revenue share fees typical for Enterprise SaaS platforms
- You require full GDPR/Omnibus compliance and control over customer data
- You are building a unique shopping experience (e.g., product configurators, subscriptions)
When to consider alternatives
MedusaJS has its limitations - in some scenarios ready-made SaaS or other stacks may be a better fit.
- Very small store with no scaling plans (Shopify/WooCommerce may suffice)
- No resources to maintain own backend and regulatory updates
- Project requiring ready-made marketplace out-of-the-box without custom development
Architecture and patterns
MedusaJS 2.0 is based on modular, event-driven architecture with clear separation into modules (products, cart, checkout, orders).
Modules and extensions
Core (products, cart, checkout, orders) plus payment, shipping and custom workflow modules. Easy to extend without forking.
Event-driven and workflow
Event bus for events (order.placed, fulfillment.created). Workflow engine for step automation and external system integration.
Headless API
REST/GraphQL API for any frontend (Next.js, React Native, mobile). Single backend source of truth for multiple channels.
Multi-region and inventory
Support for multiple regions, currencies and stock locations. Inventory management with reservations and WMS integrations.
Security and GDPR/Omnibus compliance
MedusaJS enables implementation of GDPR and Omnibus directive: consent, data minimization, retention, auditability and transparent pricing information.
GDPR
Data minimization, legal basis for processing, retention, right to erasure and portability. Event logging and change auditability.
Omnibus (EU)
Transparent pricing (pre-discount price, promotion expiry), ban on dark patterns in subscriptions and reviews.
Consent and marketing
Consent management (newsletter, cookies, profiling). Email and ad integrations respecting user preferences.
Payments and sensitive data
Integration with PCI-DSS gateways (Stripe, Adyen). No storage of full card data; tokenization and webhooks.
Performance and scalability
MedusaJS 2.0 is optimized for large catalogs and traffic - caching, indexing and stateless architecture facilitate scaling.
API and cache
Response caching (Redis), query optimization and DB indexes. Headless API enables CDN and edge caching on the frontend side.
Observability
Logging, metrics and tracing (e.g. OpenTelemetry). Monitoring workflows and event queues for fast incident response.
Horizontal scaling
Stateless backend - ability to scale instances and separate workers (fulfillment, email, integrations) in the cloud.

Frequently Asked Questions
Is MedusaJS ready for GDPR and Omnibus in the EU?
Yes. The platform does not dictate how consent or pricing is stored or displayed - you can implement data minimization, retention, audit and transparent pricing (Omnibus). At GMI we help design and implement these mechanisms for your store.
Do you have experience with large-scale MedusaJS implementations?
Yes. We deliver large-store implementations on MedusaJS 2.0 (including completion within a few months from kick-off). We will share concrete case studies upon completion of current projects.
MedusaJS vs Shopify / WooCommerce - when to choose Medusa?
Medusa gives full code ownership, no platform fees and full control over integrations and compliance. Shopify/WooCommerce are faster for a small store without custom needs; Medusa when you plan scale, ERP/PIM integrations and EU regulatory requirements.
