Magento Open Source is the default pick for most readers who need a full B2B catalogue, customer groups and tier pricing with a large extension market, while Sylius is the best pick for a custom build and Vendure is best for a B2B-first headless build. Every core here is free to download and self-host, so the real budget is hosting, development, extensions and support, not the licence. Shopware has a clear size limit that many roundups miss: shops linked to a Shopware account that pass 1 million euros in gross merchandise value over the preceding 365 days need a higher plan to retain account access.
B2B selling needs more than a checkout page. Buyers expect company accounts, price lists for each customer, quotes, repeat orders and approval steps, and most open source platforms keep at least some of those features in a commercial edition. The eight platforms below all have a free core you can self-host, and each suits a different team size, stack and budget.

The 8 best best open source b2b ecommerce platforms, in detail
Magento Open Source
Best for: Large B2B catalogues and tier pricing
Magento Open Source is the free, self-hosted edition of the platform now sold as Adobe Commerce. You download the code, install it on your own server and manage hosting, security patches and updates yourself. The core handles large catalogues, customer groups, tier pricing, multiple stores and multiple currencies.
- The trade-off is the gap to the commercial edition.
- Adobe Commerce adds the dedicated B2B suite, managed cloud hosting and vendor support, and Adobe publishes no price for it, so you must request a quot
- Plan for developer time, hosting and extensions, and confirm whether a needed B2B feature requires Adobe Commerce or a third-party extension.
- Choose it when your catalogue is large and your team can run a PHP platform.
Pros
- Full catalogue, customer group and tier pricing controls
- very large extension market
- multi-store and multi-currency support
Cons
- B2B modules such as quotes and approvals sit in Adobe Commerce, not in the open source edition
- needs developers and managed hosting
Sylius
Best for: Custom B2B builds on Symfony
Sylius is an open source ecommerce framework built on Symfony, and it suits teams that want to shape checkout, pricing and order rules to fit a specific B2B process. Sylius Standard is free under the MIT licence and covers catalogues, orders, customers, payments, promotions, shipping and taxes. Sylius Plus starts from 800 euros per year and adds enterprise modules and vendor support, while its B2B Suite adds organisation management, custom price lists and quick ordering.
- The free Standard edition does not include a native quotation workflow, so buyers cannot submit a price request online without a Plus module or custom
- The admin area is functional rather than polished, and the platform assumes Symfony knowledge, so a non-technical owner will need a partner.
- Choose Sylius when your B2B rules are unusual and your developers work in PHP and Symfony.
Pros
- Clean Symfony code that developers can extend
- B2B Suite with organisation and custom pricing options
- multi-channel catalogues
Cons
- Sylius Standard has no native online quotation workflow
- Standard support has no response-time guarantee
Shopware Community Edition
Best for: Growing B2B and B2C stores in Europe

Evolve is the first tier with B2B components such as quotes and purchasing approvals.
- Beyond adds customer-specific pricing and multi-location inventory.
- Shopware states that shops linked to an account that exceed 1 million euros in gross merchandise value over the preceding 365 days need a higher plan
- That makes the free edition a strong start for a smaller store, with a clear upgrade step as volume grows.
- Choose Shopware when you sell in Europe and want a clear upgrade path.
Pros
- Free MIT-licensed core with a visual page builder
- Rise from 600 euros per month
- Evolve adds B2B quotes and approvals
Cons
- B2B components such as quotes and purchasing approvals need Evolve from 2,400 euros per month

Vendure
Best for: B2B-first headless builds
Vendure is a headless commerce framework built on Node.js and TypeScript, designed with B2B selling in mind. The Vendure Framework is free under GPLv3 with a plugin exception, and it keeps the catalogue, orders, customers, payments, promotions, channels, dashboard and GraphQL APIs. The vendor sells three self-serve plans on top of it: Starter at 199 euros per month, Growth at 599 euros per month and Scale at 2,499 euros per month, each on a 12-month term excluding VAT.
- Enterprise starts from 60,000 euros per year.
- Starter adds company accounts, quote requests, quick order, personal shopping lists, store credit and catalogue search.
- Growth adds organisation hierarchy, managed shopping lists, gift cards, packaging units and Typesense search.

Medusa
Best for: Custom headless stores on TypeScript

The core is free to self-host under the MIT licence, and it suits teams that want to assemble their own backend.

WooCommerce
Best for: WordPress stores adding wholesale
WooCommerce is a free, open source WordPress plugin that turns a WordPress site into a store. The plugin itself costs nothing, takes no share of revenue and has no platform fee, and the vendor pricing guide puts hosting at $25 to $350 per month for most stores. The WordPress market gives you themes, payment gateways and B2B extensions for wholesale pricing, customer-specific prices, quotes and bulk ordering.
- The B2B layer is assembled from extensions, not built into the core.
- Each extension can cost $29 to $299 per year, and the total rises as you add wholesale, quote and approval tools.
- You also manage WordPress hosting, updates, backups and security, or you pay a host or agency to do it.
Pros
- Free GPL plugin with no platform fee on sales
- huge WordPress plugin and theme market

How we chose
We included only platforms with a free, self-hosted open source core that is still maintained, and we checked each one for B2B features such as customer groups, customer-specific pricing, quotes, bulk ordering, company accounts or approvals. We did not test any tool hands-on. Prices and plan limits come from official vendor pricing pages and docs opened on 12 November 2026, and the Sources list gives the page used for each item. Shopware ties account access to gross merchandise value, so a free start can still lead to a higher plan at 1 million euros in gross merchandise value over 365 days.

Frequently asked questions
What is the best open source B2B ecommerce platform for most readers?
Magento Open Source is the best default for most readers because it handles large catalogues, customer groups and tier pricing, and it has a very large extension market. Sylius is better for a custom Symfony build, and Vendure is better for a B2B-first headless build.
How much does an open source B2B ecommerce platform cost?
The core software is free in every item here, so the first cost is hosting and development. Medusa Cloud starts at $29 per month, WooCommerce hosting runs $25 to $350 per month for most stores, and Saleor Cloud Select starts at $1,599 per month.
Which is best for quotes and approvals?
Vendure Scale is the clearest match for quotes and approvals in a headless build, because it adds contract pricing, order approvals and an audit log at 2,499 euros per month. Shopware Evolve adds quotes and purchasing approvals at 2,400 euros per month.
Which is best for a small B2B store with no developers?
PrestaShop Classic or WooCommerce are the most practical starts for a small store, because both have a free core and a large module market. PrestaShop Hosted starts from 24 euros per month with hosting and support included, which suits a team that does not want to manage a server.
Do I need a developer to run an open source B2B platform?
Yes, in most cases. Every platform here needs hosting, updates, security patches and setup work, and headless options such as Saleor, Medusa and Vendure also need a storefront build. A hosted edition such as PrestaShop Hosted or Medusa Cloud reduces that work, but it does not remove integration work.
Can I start free and upgrade later?
Yes. Each platform in this list has a free self-hosted core, and most have a clear upgrade step, such as Sylius Plus from 800 euros per year, Shopware Rise from 600 euros per month, or Vendure Starter from 199 euros per month. Check the gross merchandise value limits first, so the upgrade point does not arrive sooner than you expect.
