Magento B2B vs Adobe Commerce B2B: what mid-market actually needs

Adobe Commerce ships B2B features (companies, shared catalogs, customer-group pricing, quote management) that Magento Open Source does not include natively. Adobe sales teams pitch these features as required for serious B2B operations. After building B2B portals on both Adobe Commerce and on Magento Open Source extended with third-party B2B modules, our position is more nuanced than the vendor pitches. This post covers when the Adobe Commerce licence pays for itself and when Magento Open Source plus extensions is the right call for mid-market B2B.

What Adobe Commerce B2B actually includes

Five feature families that Magento Open Source does not ship natively:

1. Companies and company users. Hierarchical accounts where one company owns multiple buyer users, with roles (purchaser, requisitioner, finance).
2. Shared catalogs. Per-company product visibility and pricing. Company A sees products at one price; company B sees the same products at a different price.
3. Quote management. Customers request a quote; sales negotiates back; customer accepts. Quote lives as an order draft until conversion.
4. Requisition lists. Saved cart-like lists that buyers can re-order repeatedly.
5. Approval workflows. Multi-step approval for orders above configurable thresholds.

These come pre-built in Adobe Commerce. They are not free features; they are licence-funded.

What Adobe Commerce B2B costs

Adobe Commerce licence is tiered by gross merchandise value, typically £20,000 to £200,000+ per year as of May 2026. The B2B feature set is included once you are on Adobe Commerce; you do not pay extra for it as a separate module.

Hosting on Adobe Commerce Cloud adds another £15,000 to £80,000 annually depending on tier. Many stores run Adobe Commerce self-hosted, which skips the cloud cost but loses some of the bundled monitoring.

Total annual Adobe Commerce B2B operating cost ranges roughly £30,000 to £300,000 depending on revenue tier and hosting model.

What Magento Open Source plus B2B extensions costs

Building equivalent functionality on Magento Open Source requires:

• B2B company management module: £400 to £1,200 lifetime or £200 to £600 annual subscription.
• Quote management module: £400 to £1,200 lifetime or similar subscription.
• Approval workflow module: usually combined with company management.
• Requisition list module: sometimes built in, sometimes a separate add-on.
• Shared catalogs: typically requires customization on top of customer-group-based pricing, ranging £4,000 to £20,000 engineering investment one-time.

Total upfront: £5,000 to £25,000. Annual operating cost: hosting, support renewals, occasional customization, typically £10,000 to £40,000 annually.

For most mid-market B2B Magento stores, the open-source-plus-extensions path is roughly 60 to 80 percent cheaper than Adobe Commerce over a three-year horizon.

When the Adobe Commerce licence pays for itself

The Adobe Commerce licence becomes worth paying for when at least two of these conditions are true:

1. Annual GMV above £20 million. The licence cost as a percentage of revenue is low enough at scale that the cost-versus-build math shifts.
2. Complex B2B feature requirements. Multi-level company hierarchies (parent companies with subsidiaries), purchase requisition workflows with three or more approval steps, complex shared-catalog rules. Building these from extensions is feasible but the upfront engineering investment grows nonlinearly with complexity.
3. Procurement requires Adobe-supported software. Some enterprise procurement teams will only buy from vetted Adobe Commerce partners. The licence is the entry ticket.
4. You want Page Builder content blocks heavily. Adobe Commerce ships Page Builder as part of the licence. Worth it if you are content-heavy.
5. You want premium support SLAs. Adobe Commerce includes support tier upgrades that the Open Source path needs to source from third-party agencies.

When Magento Open Source plus extensions is the right call

For mid-market B2B stores doing £1 million to £20 million in annual revenue, our recommendation is consistently Magento Open Source plus B2B extensions. The reasons:

• Cash flow. Annual Adobe Commerce licence is six-figure cash out the door before any product is shipped. The open-source path lets you spread the same money across engineering investment that you own.
• Vendor lock-in. Adobe Commerce dependencies (Cloud hosting requirements, proprietary Adobe Stock integrations, Page Builder dependence) make migration off the licence painful later. Open source keeps you portable.
• Feature focus. Most mid-market B2B operations use 30 to 50 percent of Adobe Commerce B2B features. Paying for all of them when you use half is poor capital efficiency.
• Extension quality has improved. B2B modules from vendors like Aheadworks, Amasty, and Mageplaza have matured to the point that the feature parity with Adobe Commerce B2B is close enough for most needs.

A specific decision framework

Before quoting an Adobe Commerce B2B build versus an Open Source plus extensions build, we ask the customer four questions:

1. What is your annual GMV today and projected three-year? Below £20 million projected, default to Open Source.
2. How many distinct customer-company tiers do you need? Up to 5 tiers, extensions are fine. Above 10, Adobe Commerce shared catalogs are better.
3. Do you have a multi-step approval workflow (more than 2 steps)? More than 2 steps, Adobe Commerce. 1 or 2 steps, extensions.
4. Does your procurement require Adobe-vetted software? If yes, licence regardless of the rest.

Honest scope of this opinion

We have shipped B2B Magento builds on both Adobe Commerce and Magento Open Source. The Adobe Commerce engagements were larger stores (typically £30M+ GMV) where the licence was a sunk cost we did not pick. The Open Source plus extensions engagements were mid-market where we were paid to choose. Our recommendations skew toward the open-source path because most of our B2B work has been in that segment. Larger stores may legitimately need Adobe Commerce for reasons that do not apply at mid-market.
