Medusa.js vs Shopify Plus for B2B Commerce: A Technical Comparison

Medusa.js vs Shopify B2B is not a fair fight on paper — one is a hosted SaaS platform with a decade of market maturity, the other is an open-source commerce engine you self-host and extend however you like. But for B2B teams building dealer portals, distributor storefronts, or quote-to-order workflows, the right comparison is not speed-to-launch. It is total control, total cost, and whether the platform can actually do what your buyers demand.

B2B commerce has specific requirements that generic storefronts handle poorly: company accounts with multiple buyers, customer-specific pricing, negotiated quotes, net-30 credit terms, tiered distributor hierarchies. Shopify Plus added B2B-native features in 2022 and has iterated since. Medusa.js, the MIT-licensed headless commerce framework, lets you implement all of these from scratch — with no app marketplace tax and no platform fee eating your margin.

What B2B commerce actually requires

Before comparing platforms, it is worth being specific about what "B2B commerce" means technically. Consumer storefronts handle one buyer, one cart, one checkout. B2B adds several layers of complexity that most platforms handle as an afterthought.

Company accounts. A single business buyer is not a single person. You need an account entity with multiple buyers, role-based permissions (approver vs. purchaser), and spending limits per user.

Customer-specific pricing. Wholesale pricing is almost never a simple percentage off. B2B typically involves negotiated per-customer price lists, volume-tiered pricing, contract pricing locked for a period, and item-level exceptions.

Quote-to-order workflows. Many B2B transactions start as a request for quote rather than a direct purchase. The buyer submits a cart-as-quote, a sales rep adjusts line items and applies custom pricing, the buyer approves, and it converts to an order.

Credit terms and payment flexibility. Net-30, net-60, purchase-order references, and invoice-on-fulfillment are standard B2B payment patterns. Online card checkout is a minority of B2B transactions.

Dealer and distributor portals. In India especially, FMCG, industrial, and pharma brands run multi-tier distribution: company to C&F agent to distributor to retailer. Each tier needs a scoped portal showing only relevant products and pricing.

Both Shopify Plus and Medusa.js address these requirements — but in fundamentally different ways.

Shopify Plus B2B: what is included

Shopify Plus launched a proper B2B feature set in mid-2022, moving away from the Wholesale channel app that was the prior workaround. As of 2026, the native B2B module includes:

• Company accounts with location-level billing/shipping addresses and multiple contacts per company.
• Price lists assigned per company or company location, supporting fixed price, percentage off, and volume pricing.
• Net payment terms (Net 7/14/30/60/90) configurable per company.
• Draft order workflows for quote-like scenarios, though without a formal quote approval flow in the storefront.
• Blended B2B/DTC storefronts — a single Shopify store can serve retail and wholesale buyers with different experiences.

Shopify Plus also benefits from its mature ecosystem: apps like Quotient, Pricelist, and Handshake extend B2B further. The Shopify admin is familiar, onboarding a sales team takes days not months, and the hosting/security/CDN burden is fully managed.

Medusa.js B2B: what you build

Medusa.js (now at v2.x) is a Node.js/TypeScript headless commerce framework. "Headless" means there is no built-in storefront — you bring your own frontend (Next.js, Remix, a mobile app, whatever fits). The backend is a set of modules — cart, product, order, customer, payment, fulfillment — that you compose and extend.

For B2B, Medusa.js provides the primitives; you build the features:

• Customer groups and price lists are core features — you can create as many pricing tiers as you need with any logic.
• Custom modules let you implement a Quote entity with its own state machine (draft → submitted → negotiated → accepted → converted to order).
• API routes are extendable — add /quotes, /approval-workflows, /credit-limits as Express middleware without forking the core.
• Multi-tenant / multi-store setups are achievable with a single Medusa instance serving multiple storefronts under different domains.

Because you own the code, there is no ceiling. The B2B logic lives in your repository, version-controlled, deployable to your infrastructure, and integrable with your ERP via direct API calls.

Mith Tech has built Medusa.js-powered commerce solutions for B2B clients in manufacturing and distribution, including direct ERPNext sync for inventory, pricing, and order data. If you are already running ERPNext or exploring Frappe, this integration path is documented and battle-tested.

Head-to-head: B2B features comparison

The table tells a clear story: Shopify Plus wins on speed and out-of-the-box coverage for standard B2B. Medusa.js wins on depth, ownership, and cost at scale.

Total cost of ownership

This is where the comparison shifts most significantly for growth-stage B2B businesses.

Shopify Plus starts at approximately $2,300/month on an annual plan (roughly $27,600/year) for revenue under $800K. Above that threshold, pricing moves to 0.25% of monthly revenue. A business doing $5M GMV/year pays around $12,500/year in platform fees alone. At $10M GMV, that is $25,000/year — and this is before app subscriptions, Shopify Payments margins, and agency retainers to configure the platform.

Medusa.js has no platform fee and no revenue share. Your costs are:

1. Hosting — a production Medusa backend on a managed cloud (Railway, Render, AWS, GCP) runs $50–300/month depending on traffic.
2. Implementation — building B2B features, storefront, and integrations is a real engineering project. Budget 3–6 months for a serious implementation.
3. Ongoing maintenance — a part-time developer or an agency retainer.

For a business doing $2M+ GMV/year with significant B2B customization needs, the Medusa.js TCO typically crosses below Shopify Plus within 18–24 months of launch. The crossover point depends heavily on how many paid Shopify apps you would need to replicate the functionality you build natively in Medusa.js.

Headless flexibility and frontend ownership

One underrated B2B advantage of Medusa.js is the storefront architecture. Shopify Plus gives you Liquid templating (with Hydrogen as a React alternative, though adoption is still limited). You are working within Shopify's rendering constraints.

Medusa.js is purely an API backend. Your storefront is a separate application — a Next.js app, a React Native mobile app, an internal admin portal, or all three consuming the same API. For B2B use cases this matters:

• A manufacturer can run a DTC Shopify store for consumers and a Medusa.js-powered dealer portal for distributors — two systems optimised for their respective buyers.
• Or they can consolidate on Medusa.js and serve both through a single API with buyer-type-aware pricing and catalogue rules.
• A distributor portal can be a full PWA with offline order capture for sales reps in the field, something Liquid templates cannot realistically deliver.

For B2B commerce where the buyer experience is often a proprietary competitive advantage — not a generic storefront — owning the frontend is a meaningful distinction.

Developer experience and ecosystem maturity

Shopify Plus has the larger developer ecosystem by a wide margin. There are thousands of Shopify developers, a mature Partner Programme, and an app store with solutions for nearly every vertical. If your B2B requirements are close to standard, you can likely buy what you need.

Medusa.js has a smaller but fast-growing community (over 25,000 GitHub stars as of early 2026), strong TypeScript support, and a plugin/module system that makes packages shareable. The core team ships steadily and the v2 architecture (released late 2024) significantly improved module isolation and developer ergonomics.

The honest gap is in vertical-specific apps. Shopify has B2B apps built for apparel, food service, industrial supply, and dozens of other verticals. Medusa.js does not. If your B2B needs are covered by an existing Shopify app, you should at least price that app before committing to a custom Medusa build.

When to choose Shopify Plus

Shopify Plus makes sense when:

• You need to launch quickly (under 3 months) and your B2B requirements are close to standard.
• Your team has no in-house engineering capacity and you do not want a development agency dependency.
• Your GMV is under $1–2M/year and the platform fee is a manageable line item.
• Your B2B flows are mostly catalogue + price list + net terms, without custom approval chains.
• You want a fully managed, secure, globally-CDN-served infrastructure with zero ops burden.

When to choose Medusa.js

Medusa.js makes sense when:

• Your B2B requirements are custom enough that Shopify Plus would need significant app spend or bespoke API work anyway.
• You need a quote-to-order flow, custom approval hierarchies, or multi-tier distributor portals with scoped catalogues.
• Your GMV is growing toward or past the point where Shopify Plus's revenue-based pricing becomes material.
• You want full data ownership — customer data, order history, pricing logic — on your own infrastructure.
• You are integrating with an ERP (especially ERPNext or Frappe) and want a direct, maintainable API connection rather than webhook chains.
• Your frontend needs are complex: mobile apps, offline-capable rep portals, or embedded commerce within an existing business application.

Frequently asked questions

Is Medusa.js production-ready for B2B commerce?

Yes. Medusa.js v2 is production-stable, used by companies with significant transaction volumes, and actively maintained by a commercial entity (Medusa Commerce Inc.) with enterprise support available. The framework ships with a test suite, TypeScript types, and documented extension patterns. The main readiness gap is not the framework itself — it is your team's capacity to implement and maintain B2B features on top of it.

Can Shopify Plus handle complex distributor hierarchies?

Not natively. Shopify Plus B2B supports company accounts and location-level pricing, but multi-tier distributor hierarchies — where a C&F agent manages a set of distributors who each have their own scoped portal — require significant custom Storefront API work or third-party multi-store apps. If this describes your model, Medusa.js or a dedicated B2B platform is worth evaluating alongside Shopify Plus.

How long does a Medusa.js B2B implementation take?

A realistic timeline for a production-grade B2B storefront with custom pricing, quote-to-order, company accounts, and ERP integration is three to six months with a focused team. A phased approach — launch with price lists and company accounts first, then add quote workflows — can compress the initial go-live to eight to twelve weeks.

Does Mith Tech offer fixed-price Medusa.js implementations?

Yes. Mith Tech offers scoped Medusa.js engagements covering storefront build, admin customization, payment gateway integration, and ERPNext sync. Pricing depends on scope; we typically work from a discovery engagement to define the right contract structure. Contact us to start that conversation.

What payment gateways work with Medusa.js in India?

Medusa.js has official plugins for Stripe, PayPal, and Razorpay, and the payment module interface makes it straightforward to add any gateway that exposes a REST API. For Indian B2B commerce, Razorpay is the most common choice, covering UPI, net banking, and credit cards. Purchase-order and invoice-based payment flows are handled outside the gateway at the order-management layer.

Can we run Shopify Plus for DTC and Medusa.js for B2B at the same time?

Yes, and some businesses do exactly this — Shopify Plus serves retail consumers, Medusa.js powers the dealer or distributor portal, and an ERPNext instance sits behind both as the system of record. Both platforms expose APIs, so inventory, product data, and order information can be synchronised through a middleware layer or directly via ERPNext's REST API.
