Can you replace Adobe Commerce B2B with open source?
Most Adobe Commerce B2B features can be covered by Magento Open Source extensions, Shopware's paid plans or custom development, but not all of them, so each gap has to be checked before you commit. The usual trigger is a renewal or licensing change that puts company accounts, negotiated pricing, quotes and purchase orders behind a paid edition, even though the storefront itself works well. Because these capabilities are a set of modules rather than the whole platform, the replacement can be scoped module by module. The rest of the catalog, checkout, theme and integrations can usually stay on Magento Open Source while the B2B layer is handled separately.
Start with an inventory. In your admin, list every B2B feature that is actually switched on and used by buyers: company accounts and roles, shared catalogs, negotiable quotes, purchase orders, requisition lists and any custom approval steps. Then check which Adobe Commerce modules and database tables support each one in your installation, and which of your integrations, such as the ERP or pricing feed, read or write that data. Usage often turns out narrower than the license suggests. A feature with no active users is a removal decision, not a replacement project, and each feature you keep needs a named owner who can sign off on the replacement's behavior.
For each remaining feature, ask the extension vendor or Shopware team for written confirmation of four things: compatibility with your Magento Open Source version and its PHP requirements, support for your company hierarchy and approval rules, how negotiated prices sync with your ERP, and who maintains the code after go-live. Custom work carries a one-time build cost plus ongoing maintenance that you own. Shopware's B2B quotes and approvals sit in its paid Evolve plan, and Shopware's pricing page ties plan cost to gross merchandise value, so ask how that cost changes as your order volume grows. Run the full B2B buying journey on staging before you cut over.
Which B2B capability maps to which open-source option
This table maps each Adobe Commerce B2B capability to a Magento Open Source route and a Shopware route, with a coverage rating for each. Read partial as a feature area that still needs a scope check, and none-known as no verified equivalent in this review. Confirm each extension's current compatibility with your target Magento version before you rely on it.

Which open-source path fits your B2B store
Adobe Commerce B2B features such as company accounts, shared catalogs, quotes and purchase orders can be rebuilt on three different paths. Each carries a different mix of extension risk, licensing terms and engineering effort, so the right choice depends on how much of your B2B logic you want to own.
Stay on Magento Open Source
Keep the Magento codebase and rebuild B2B features with community or third-party extensions and custom modules. This fits teams with in-house Magento developers and an existing catalog and integration footprint they do not want to rewrite. The main trade-off is that you own extension compatibility on every upgrade. Check each B2B extension against the exact Magento Open Source version and PHP, MySQL and OpenSearch versions you plan to run, and confirm who patches it when Adobe ships a new release line.
Move to Shopware with paid B2B
Shopware's Community Edition is MIT licensed, but shops linked to an account that generate more than 1 million euros in gross merchandise value over the preceding 365 days must move to a paid plan. B2B quotes and approvals sit in the Evolve plan, which is priced at 2,400 euros per month according to Shopware's pricing page. The trade-off is a recurring licence fee tied to GMV, and the price is based on GMV and other individual factors, so ask for a written quote before you plan the budget.
Build B2B on a headless platform
Saleor and Medusa expose commerce logic through APIs, so company accounts, price lists and approval steps become services you design and own. Saleor is BSD-3-Clause and offers per-channel pricing and a GraphQL API. Medusa's core is MIT licensed, but role-based access control in its Enterprise Edition requires a commercial agreement with MedusaJS, Inc. Budget for a separate storefront and for the custom approval workflow, which no open-source platform supplies out of the box.
Check the B2B gaps first
Before choosing a path, list every B2B feature your store uses in production, including company hierarchies, negotiated price tiers, requisition lists and purchase order payment terms. Map each one to an existing extension, a paid plan feature or custom code. Features with no open-source equivalent are the ones that drive build cost, so they belong at the top of your written scope.
Plan the catalog and customer data move
Company accounts, shared catalogs and customer-specific prices must survive any move. Export and map these structures early, and confirm that the target platform can represent contract pricing per company. Test order history, reorder lists and tax settings on staging, since B2B buyers notice errors in negotiated terms faster than any other shopper group.
Price the ongoing support model
Each path shifts cost between licence fees, extension subscriptions, hosting and developers. Ask any implementation partner to separate one-time build work from recurring upgrades, security patching and extension maintenance. Confirm the support response times and the support model in writing, because self-hosted paths carry these costs on your own team unless a retainer covers them.
How B2B features sit on top of Magento Open Source
Adobe Commerce B2B features are additional modules installed on the same Magento codebase that Magento Open Source uses, so an open-source replacement is usually a set of extensions or custom modules that must match the Magento 2.4 release you run. Before choosing any extension, confirm that it declares support for your exact release line. Magento Open Source source files are licensed under the Open Software License 3.0 (OSL-3.0), with AFL 3.0 also included in the distribution, according to the magento2 GitHub repository. That license lets you use and modify the core, but it does not give you the B2B modules, which Adobe sells as part of Adobe Commerce. Check each B2B module's own license and vendor terms in the same way.
The platform stack is fixed by Adobe's requirements, not by the extension vendor. For 2.4.9, Adobe lists PHP 8.5, MySQL 8.4 or MariaDB 12.3 (recommended) or 11.8, OpenSearch 3, Redis or Valkey 9, RabbitMQ 4.3, Composer 2.10 and nginx 1.30 on Linux x86-64, and states that it supports only the listed combinations. For 2.4.8-p5, the list is PHP 8.4 or 8.3, MySQL 8.4 or MariaDB 11.4 or 11.8, OpenSearch 3, Redis or Valkey 8.1, RabbitMQ 4.3, Composer 2.10, nginx 1.30 and Varnish 8. Ask each B2B extension vendor to confirm in writing which of these combinations its test matrix covers, because an extension tested on a different PHP or search engine version is a support risk you carry.
Caching also differs by hosting model. Adobe documents Varnish as the full-page cache accelerator for self-managed installations, while cloud-hosted Adobe Commerce uses Fastly instead. If you move B2B storefronts from Adobe's cloud to your own servers, plan to deploy and configure Varnish yourself and retest any B2B pricing or catalog pages that depend on cache behavior, since shared catalogs and negotiated prices are often customer-specific and easy to cache incorrectly.
How to move company accounts, catalogs and quotes off Adobe Commerce B2B
This sequence turns Adobe Commerce B2B data, workflows and approvals into a documented, tested set of company accounts, catalogs and quote processes on a self-hosted target, with a clear decision on every open transaction.
Audit B2B modules and data in use
Your team, with a developer who knows the codebase, lists every Commerce-only B2B feature the store actually uses: company accounts, shared catalogs, company credit, negotiable quotes, purchase orders and requisition lists. For each one, record how many companies, roles, price rules and open transactions depend on it. Confirm with Adobe's documentation and your installed modules which features belong to Adobe Commerce and which are in Magento Open Source. The step is done when you have a written inventory that marks each feature as used, unused, or replaceable by an extension or custom code.
Export company, customer group and catalog data
Extract company records, role assignments, customer groups, shared catalog membership, tier and catalog pricing, and product attributes from the database or through the store's APIs into version-controlled files. Keep exports separate from the live store so the source remains untouched. Check that every company maps to its users, payment terms and addresses. The output is a set of exports with row counts that you reconcile against the live store, and a note on any data that has no direct target field.
Rebuild shared catalogs and price rules on the target
Recreate the catalog structure, company-specific prices and quantity tiers on the chosen target. For Magento Open Source, this usually means extensions or custom modules because the B2B layer is part of Commerce. For Shopware, check which B2B functions are in its paid plans and which need custom work. For Saleor or Medusa, model company-specific pricing through channels, price lists or custom services. Confirm each platform's capability before committing. The step is done when a sample of companies sees the same prices and visible products on target as on the source.
Replace quote and purchase order workflows
Rebuild negotiable quotes, purchase order submission, approval chains and requisition lists as either a supported extension, a paid plan feature or custom code, depending on the audit. Define who approves what, what limits trigger escalation, and how a quote becomes an order. Record every approval rule in a document the business owners sign off. The output is a workflow map with each path tested on staging using test accounts for each role.
Decide what happens to open quotes and purchase orders
Agree in writing whether each open quote and in-flight purchase order migrates to the new system or finishes on Adobe Commerce. Migrating open transactions requires mapping statuses, line items, negotiated prices and approval history, which is usually more work than migrating closed records. Finishing on the old system means keeping it running until those transactions close. Confirm the decision with finance and sales, and set the date after which no new quotes are created on the old store. The step is done when every open transaction has a named owner and a documented outcome.
Test approvals, tax and payment terms on staging
Run end-to-end test orders on staging for each company type, including approvals, partial shipments, tax exemptions, credit limits and payment terms. Compare totals and tax lines against the live store for the same cart. Check that your tax engine and payment gateway behave as expected for B2B accounts, and confirm the results with your finance team. The output is a signed test report that lists each scenario, the expected result, the actual result and any defects fixed before cutover.
Cut over with a tested rollback plan
Schedule the cutover window with the business, freeze catalog and company changes on the source, run the final data load, and repeat the reconciliation checks. Keep the Adobe Commerce store and its database available until the agreed exit point. Write the rollback steps, who can trigger them, and how customer communications change if you revert. The step is done when the target passes the reconciliation, the first live company orders complete, and the rollback path has been rehearsed on staging.
What do buyers ask before replacing Adobe Commerce B2B?
How much effort does replacing Adobe Commerce B2B features take?
Effort depends mostly on how many B2B features your store actually uses and how much custom logic sits on top of them. Company accounts, shared catalogs, negotiated quotes, purchase orders and requisition lists each need a replacement, whether that is a Magento Open Source extension, a paid Shopware plan feature, or custom development. Before estimating, inventory which modules are enabled, which customer groups and price rules depend on them, and which ERP or credit integrations feed them. No public source supplied here gives a effort figure for this work, so ask each candidate vendor and implementation partner to price against your written inventory.
Can our in-house team replace Adobe Commerce B2B without a partner?
Some teams can, especially if they already run Magento Open Source in production and have developers who know its module system. The work usually spans payments, tax, ERP sync, pricing rules and security review, so the skills gap is often in integration and testing rather than storefront code. Check whether your team has owned a Magento upgrade cycle before, who will patch the stack after go-live, and whether staging can mirror production. A fixed-scope engagement from DeployOpen can cover planning, implementation, hardening and documentation in your own infrastructure, which gives you a written scope to compare with an internal plan.
How long does a B2B migration take, and what sets the schedule?
No supplied source gives a duration for this migration, so treat any single number with caution. The schedule is usually set by the number of integrations, the volume of custom B2B logic, the amount of data to move, and how many test cycles your business requires before cutover. Your Adobe Commerce contract end date and your support window also shape the plan. Ask any partner for a milestone plan with named dependencies, and confirm the rollback approach for each cutover step.
Which Adobe Commerce B2B features have no open-source equivalent?
Not every B2B feature has a drop-in open-source counterpart. Magento Open Source covers core ecommerce, but company hierarchies, shared catalogs, quote negotiation and requisition lists are typically delivered by Commerce-only modules or by extensions of varying maturity. Shopware's paid B2B features sit on a different platform, so moving there means rebuilding logic rather than reusing it. Treat any feature without a verified replacement as a gap to design around, and confirm each capability against the extension's code, release history and documentation before you commit.
How do Adobe's 2.4.x support dates affect our B2B timing?
Adobe's lifecycle policy gives each 2.4.x release three years of standard support from general availability. Per Adobe's lifecycle policy, standard support for 2.4.6 ends on August 11, 2026, 2.4.7 on May 31, 2027, 2.4.8 on May 31, 2028 and 2.4.9 on May 31, 2029. If your store runs 2.4.6 or 2.4.7, plan the B2B exit before those dates, or upgrade first, because staying on an unsupported release raises security and compatibility risk. Confirm your current version and your contract terms in writing with Adobe.
What should a fixed-scope quote for this work include?
A fixed-scope quote should list the written scope, deliverables, acceptance criteria and timeline before work starts. Ask for an inventory of every B2B feature in use, a mapping to a named replacement or custom build, the integrations in scope, and the test plan for staging and cutover. Also ask what is excluded, how change requests are priced, what documentation and handover you receive, and which post-launch support or upgrade retainer is available. DeployOpen does not publish a price list, so a quote follows from the written scope.
Does moving B2B features affect security and compliance evidence?
Yes. Company accounts, approval workflows and purchase orders often hold access control and financial approval logic, so they need the same review as payments. Adobe documents Content Security Policy support from 2.3.5, with restrict mode by default on payment pages from 2.4.7, and self-managed installs use Varnish for full-page caching. Your replacement stack must keep equivalent controls and produce evidence for auditors. DeployOpen prepares systems and evidence for compliance assessments, but independent auditors issue any report or certification.
What the B2B replacement costs in components
Cost comes from components, not a single licence line. Adobe Commerce bundles its B2B features into a paid edition, so moving to Magento Open Source means paying separately for each piece the paid edition used to supply. The one-time work is the audit of which Commerce-only modules and data your store uses, the selection and testing of B2B extensions for company accounts, shared catalogs, quotes, purchase orders and requisition lists, any custom development for gaps with no extension equivalent, data migration of companies and negotiated prices, and regression testing on staging. Ask each vendor or partner to price these as separate line items so you can see which work is the custom part.
Recurring costs are hosting and the search, cache, queue and database services Magento Open Source needs, extension licences or subscriptions, security patching, upgrades and the developers who maintain the store. Adobe's published lifecycle gives each 2.4.x release three years of standard support, so budget for an upgrade path at each end-of-support date, and confirm the chosen extensions support the same Magento release. Costs go up with the number of custom B2B rules, integrations with ERP or pricing systems, and the size of the catalog. For comparison, Shopware publishes its plan prices on its pricing page, with its Evolve plan listed at 2,400 euros per month for B2B quotes and approvals. That figure is Shopware's own list price, and it does not include your migration or the extension and theme work you would still need to fund.
Before you sign a quote, ask for the scope of each B2B feature, the named extension and its licence model, who patches the extension after a Magento security release, and what happens to the work if the extension stops being maintained. Ask whether the price covers staging tests and rollback. Ask for the hours and roles, not only the total, so you can compare the in-house and partner options on the same basis. Scope and timing should be written down before work starts, and the scope should list the B2B features that will be replaced one by one.
How DeployOpen scopes and delivers a B2B module replacement
DeployOpen plans, implements, customizes, integrates, hardens, backs up, upgrades, documents and supports self-hosted open-source platforms inside your own infrastructure. For B2B replacements, that means turning company accounts, shared catalogs, quotes, purchase orders and requisition lists into a written scope before any code changes, then delivering them in your own cloud account, data center or air-gapped network.
How we scope
- Inventory which Adobe Commerce B2B features your store uses, including company accounts, shared catalogs, quotes and requisition lists
- Map each feature to a Magento Open Source extension, a paid Shopware B2B plan or custom work, and record gaps in writing
- Agree deliverables, timelines and acceptance tests in a fixed-scope document before work starts, with ongoing support available as a retainer
How we build
- Set up a staging environment that matches your production hosting, including the PHP, database, search, cache and queue versions your chosen release supports
- Implement or customize B2B modules, then integrate pricing, tax, ERP and payment connections your buyers depend on
- Test quote approval paths, purchase order workflows and shared catalog permissions with role-based scenarios before any cutover
How we hand over
- Document company account roles, catalog rules, quote workflows and the configuration keys that control them for your own teams
- Deliver runbooks for backups, patching, rollback and the cutover sequence so your staff can operate the store without DeployOpen
- Provide evidence packs of tests, configurations and access controls that your internal teams or external auditors can review
How we support
- Plan security patching and minor upgrades against each release line's support dates, confirmed with you before each window
- Offer ongoing support, upgrades and continuous security testing as retainers, scoped in writing
- Confirm with your extension vendors and in your own environment which B2B modules remain compatible after each upgrade
