5 Best Open Source B2B eCommerce Platforms in 2026

An open source B2B eCommerce platform lets you sell to other businesses online while you keep full control of the code and your customer data.

Manufacturers, wholesalers, and distributors use these platforms to move bulk orders and quotes off email and spreadsheets.

This guide compares five open source platforms for B2B eCommerce, so you can see which B2B features are free and what the paid editions add.

If you want the short answer, Bagisto is our top pick because its full B2B suite is free, while most rivals keep key B2B tools in paid editions.

We last updated this guide in October 2026, so that each version number and edition detail matches the official sources.

Use this table to build a quick shortlist, then read the detailed review of each platform further down the page.

Platform	Best For	Tech Stack	Free B2B Features	License
Bagisto (Best Overall)	Wholesalers and distributors that want a full free B2B suite	PHP (Laravel)	Company accounts, roles, credit, RFQ, quotes, purchase orders, quick order	MIT
OroCommerce	Mid-size and large manufacturers with complex buyer structures	PHP (Symfony)	Customer hierarchies, price lists, RFQ, shopping lists	OSL-3.0 (Community Edition)
Spree	Ruby on Rails teams building API-first B2B portals	Ruby on Rails	Price lists, customer segments, gated storefronts, company accounts	BSD-3-Clause (Community Edition)
Sylius	Symfony teams building custom B2B workflows	PHP (Symfony)	Customer groups and channel pricing (B2B Suite is paid)	MIT (Community Edition)
nopCommerce	.NET teams selling to both businesses and consumers	C# (ASP.NET Core)	Role-based prices, tier pricing, call for price, multi-warehouse	nopCommerce Public License

All five platforms are free to self-host, but OroCommerce, Spree, and Sylius move some important B2B features into paid editions.

It is store software built for business buyers, where you can read and change the source code instead of renting a closed SaaS product.

Business buyers order differently from shoppers, so the platform must handle company accounts, negotiated prices, and approval steps.

B2B vs B2C eCommerce

A B2C shopper pays a public price and checks out alone, while a B2B buyer often needs a quote, a manager’s approval, and payment on credit terms.

That is why a regular store with a B2B plugin often struggles, because the whole buying flow changes rather than just the price.

Must-Have Features in a B2B eCommerce Platform

• Company accounts: one business with many buyers, each with their own role
• Customer-specific pricing: price lists, tier prices, and contract rates
• Request for quote (RFQ): buyers ask for a price and the seller replies with an offer
• Quick and bulk ordering: order by SKU, upload a CSV, or reuse a saved list
• Approvals and purchase orders: managers sign off before an order is placed
• Credit and payment terms: buyers pay later within an agreed limit

We only included platforms with a free, open source edition you can self-host, so closed SaaS products were left out.

Webkul has built eCommerce software since 2010, and our teams deliver B2B stores and B2B marketplaces for clients around the world.

Each review below explains which B2B features you get for free and which kind of business gets the most from the platform.

Bagisto B2B Commerce adds a complete B2B suite to the Laravel-based Bagisto platform, and it is released under the MIT license.

Company owners manage their own buyers and orders from a dashboard, which takes routine account work off your sales team.

Why We Ranked Bagisto #1:

Company credit, quotes, and purchase orders are free in Bagisto, while several other platforms here charge for an enterprise edition to get them.

You can test the whole buying flow first on the B2B live demo, before you install anything.

Key B2B Features

• Company registration with custom company attributes
• Company users with role-based permissions
• Sales representatives assigned to company accounts
• Company catalogs and company credit limits
• Requisition lists and quick order by SKU or CSV upload
• Request for quote, quote handling, and purchase orders

If you want many suppliers selling to business buyers, the Bagisto B2B Marketplace adds RFQs and supplier microsites.

AI Tools and Scale

B2B catalogs are often large and thinly described, and Bagisto’s Magic AI drafts product content and images inside the admin panel.

Bagisto has also been tested with 10 million products, so a wholesale catalog with many SKUs sits well within its range.

Real distributors already run on it, such as Onyx, a US B2B distributor that manages over 1,200 SKUs online.

Bagisto Pricing

Bagisto and its B2B suite are free to download (latest release v2.4.12, September 2026), so you only pay for hosting and custom work.

Best for: wholesalers, distributors, and manufacturers that want a complete B2B store without paying for an enterprise license.

OroCommerce is a PHP platform built on Symfony, and unlike most rivals it was designed for B2B selling from day one.

Its customer hierarchies mirror how large companies buy, with parent accounts, child accounts, and buyers who each see their own prices.

Key B2B Features of OroCommerce

• Customer hierarchies with roles and detailed permissions
• Multiple price lists for customer groups and single accounts
• Request for quote and quote negotiation
• Shopping lists for repeat orders
• Workflow engine for custom order and approval steps

OroCommerce Pricing

The Community Edition is free under OSL-3.0 (latest version 7.0), and it suits smaller B2B businesses that run a single website.

Enterprise Edition is quote-based, and it adds multi-website and multi-warehouse support for larger B2B operations.

Best for: mid-size and large manufacturers with complex buyer accounts and a budget for an enterprise license as they grow.

Spree Commerce is an open source platform built on Ruby on Rails, with a REST API and a TypeScript SDK for custom frontends.

Gated storefronts hide products and prices until a buyer’s account is approved, which many wholesale brands need from day one.

Key B2B Features of Spree

• Price lists for volume and contract pricing
• Customer segments for targeted catalogs and promotions
• Gated storefronts and company accounts
• Multi-warehouse stock and delivery rules

Spree Pricing

The Community Edition is free under BSD-3-Clause, and the latest stable release is v5.6.1 from July 2026.

Buyer roles, spending limits, approval workflows, and quick-order forms need the paid Enterprise Edition, which is quoted per project.

Best for: Ruby on Rails teams that want an API-first B2B portal and will build their own buyer experience.

Sylius is an open source commerce framework built on Symfony, and it suits B2B projects whose rules do not fit a standard store.

Developers shape checkout, pricing, and approvals in clean Symfony code, which keeps heavy custom work easier to test and maintain.

Key B2B Features of Sylius

• Customer groups and channel-based pricing in the free edition
• B2B Suite in Sylius Plus for quick shopping and order management
• Request for quote, RBAC, and multi-source inventory in Sylius Plus
• Elesto, a preconfigured B2B setup for manufacturers and wholesalers

Sylius Pricing

Sylius costs nothing to self-host under the MIT license, and the latest release is v2.3 from September 2026.

Most ready B2B tools sit in Sylius Plus, which is priced on your online sales (GMV) and the modules you choose.

Best for: Symfony teams that want to build a custom B2B store and are ready to pay for Sylius Plus to speed it up.

nopCommerce is a free platform built on ASP.NET Core, and it serves business and retail buyers from the same store.

Customer roles drive most of its B2B setup, because each role can have its own prices, payment methods, and catalog access.

Key B2B Features of nopCommerce

• Tier pricing for bulk discounts, set per customer role
• “Call for price” to hide prices from guests
• Access control lists to limit products and pages by role
• Multi-warehouse inventory tracking

nopCommerce Pricing

nopCommerce is free to download, and the latest stable release is 4.90.8 from September 2026.

Its license asks you to keep a “Powered by nopCommerce” link on the store, unless you pay for the option to remove it.

Quotes and company accounts are not built in, so a full B2B portal usually needs paid plugins or custom development.

Best for: .NET teams that sell to both businesses and consumers and mainly need role-based pricing.

The license is often free, but the real cost depends on whether the B2B features you need sit in the free or the paid edition.

Platform	Free Edition	Paid Edition	Quotes and Approvals
Bagisto	Free, full B2B suite	Not needed for B2B	Free
OroCommerce	Community Edition	Enterprise Edition, quote-based	RFQ free; multi-website in Enterprise
Spree	Community Edition	Enterprise Edition, quote-based	Approvals in Enterprise
Sylius	Community Edition	Sylius Plus, priced on GMV	RFQ in Sylius Plus
nopCommerce	Free with “Powered by” link	Paid link removal and plugins	Needs plugins

An enterprise license can cost more than the whole build, which is why it pays to check the edition table before you choose.

The right B2B commerce platform depends on how complex your buyers are and which programming language your team already uses.

• Best overall, with a free B2B suite → Bagisto
• Complex buyer hierarchies at scale → OroCommerce
• Ruby on Rails team, API-first portal → Spree
• Symfony team, custom workflows → Sylius
• .NET team selling B2B and B2C → nopCommerce

Before you commit, run one real quote and one bulk order on your top two picks, because that shows how well each fits your buyers.

What is the best open source B2B eCommerce platform?

Bagisto is our top pick for 2026, because its full B2B suite, including quotes and company credit, comes free.

Is there a free B2B eCommerce platform?

All five platforms in this guide are free to self-host, although OroCommerce, Spree, and Sylius keep some B2B tools in paid editions.

Does Magento Open Source include B2B features?

Magento’s native B2B module is only part of the paid Adobe Commerce edition, so Magento Open Source needs extensions for B2B selling.

Which B2B platforms support request for quote?

Bagisto and OroCommerce include RFQ in their free editions, while Sylius offers it in Sylius Plus and nopCommerce needs a plugin.

What is the difference between a B2B store and a B2B marketplace?

A B2B store sells your own products to business buyers, while a B2B marketplace lets many suppliers sell to those buyers on one platform.

Can I sell to both businesses and consumers from one store?

You can, since Bagisto and nopCommerce both serve B2B and B2C buyers from one store, with different prices for each customer group.
