The State of Magento B2B in the US: 2026 Market Data and What It Means for Merchants

B2B buyers have spent the last several years adopting the exact habits B2C shoppers normalized years earlier, self-service research, online ordering, and low tolerance for clunky checkout, and the market data finally reflects it. Below is what the 2026 numbers actually show about US B2B ecommerce growth, where Adobe Commerce fits into that market, and which specific B2B features are seeing real adoption versus which ones are still mostly marketing copy.

A caveat worth stating upfront: B2B ecommerce market-size figures vary more than almost any other stat in this industry, different research firms define “B2B ecommerce” differently (web-only transactions vs. EDI vs. total B2B commerce), which produces headline numbers that can look contradictory even when neither source is wrong. We've named each source and what it's actually measuring so you can use the number that matches your own context.

US B2B Ecommerce Growth Is Real, Even in a Flat B2B Economy

According to figures reported by Digital Commerce 360's B2B Ecommerce Market Forecast, as summarized by industry outlets including Uncap and Xorosoft, US B2B ecommerce grew 13% to reach $2.93 trillion, a notable acceleration given that total B2B sales (online and offline combined) rose just 0.4% over the same period, as buyers delayed projects and scrutinized spending. That combination matters: ecommerce isn't growing because the overall B2B economy is booming, it's gaining share within an otherwise flat market, because digital channels are increasingly where B2B buyers choose to transact even when budgets are tight.

A separate figure cited in industry roundups, including Elogic's B2B ecommerce statistics summary, puts US B2B ecommerce site sales specifically at $2.297 trillion in 2024, up 10.5% year-over-year, with a projection to reach $3.027 trillion by 2028 at a 7.8% compound annual growth rate. The two figures aren't measuring identical things, but they point the same direction: steady, high-single-digit-to-low-double-digit growth in the US specifically, regardless of which measurement methodology you use.

Where Adobe Commerce Sits in the B2B Platform Market

Adobe Commerce holds an estimated 12% of the B2B commerce platform market according to industry analysis from Elogic's Adobe Commerce B2B guide, positioning B2B as arguably the platform's strongest competitive ground in 2026, stronger than its position in pure B2C. That lines up with the structural reality of B2B commerce: complex manufacturers and distributors need company hierarchies, shared catalogs, contract pricing, negotiable quotes, requisition lists, PunchOut, and EDI support, capabilities that Adobe Commerce has built out more extensively than most competing platforms.

Vendor-reported figures from Adobe itself, cited by multiple 2026 industry sources, claim roughly 60% of Fortune 1000 companies with direct-to-consumer ecommerce channels rely on Adobe Commerce for storefront management, including named brands like Nike, Hermès, Panasonic, and HP. Treat that specific figure as directionally useful but vendor-sourced, it comes from Adobe's own marketing material rather than an independent research firm, so it's worth confirming against Adobe's current published materials before quoting it externally.

Which B2B Features Are Actually Seeing Adoption

Feature adoption data is more concrete than market-size estimates, and more useful for deciding what to actually build. A recent Adobe-run survey, referenced in Adobe's own B2B commerce trends coverage, found that 57% of B2B respondents said they're offering customer-specific pricing, compared to just 24% of B2C respondents, a clear signal that negotiated, account-based pricing is now table stakes for B2B sellers rather than a differentiator.

The same survey found 25% of B2B providers now offer buy-now-pay-later (BNPL) options, a notably fast adoption curve for a payment method that started as a B2C trend. Combined with the broader feature set Adobe Commerce B2B supports, company accounts, shared catalogs, negotiable quotes and quote templates, and purchase order approval workflows, the pattern is consistent: the B2B features seeing real adoption are the ones that remove friction from large, recurring, account-based purchasing, not the ones that simply port over B2C conveniences.

• Customer-specific pricing is now standard, not advanced. At 57% adoption among B2B sellers, a storefront without account-based pricing increasingly looks behind rather than lean.
• BNPL adoption is accelerating in B2B specifically. 25% adoption for a relatively new B2B payment option suggests this moves from differentiator to expectation faster than most B2B features typically do.
• Self-service and approval workflows are the real battleground. Company hierarchies, requisition lists, and purchase order approvals are the features that actually reduce the sales-rep workload B2B ecommerce is meant to offset, not just the storefront UI layer.
• Platform choice matters more in B2B than B2C. With Adobe Commerce holding an estimated 12% share of a platform market built around complex, account-based requirements, the practical gap between platforms is wider in B2B than it typically is for straightforward B2C catalogs.

What This Means for US Merchants Running or Considering Magento B2B

The growth numbers support the investment case, US B2B ecommerce is growing in the high single digits to low double digits across every measurement methodology we found, even against a flat broader B2B economy. The feature-adoption data gives a clearer build priority than most roadmaps start with: customer-specific pricing and account-based workflows are no longer advanced asks, they're the baseline a B2B buyer now expects before they'll consider self-service ordering a real alternative to calling their rep.
