B2B e-commerce
B2B e-commerce is the digital channel through which businesses buy products and parts from other businesses, covering everything from wholesale apparel and packaged goods to industrial MRO supplies, electronic components and chemicals. The category is structurally larger than B2C e-commerce by several multiples - global B2B online sales cleared $20T in 2024 across direct manufacturer websites, distributor portals and horizontal marketplaces - but digitised at a slower pace because catalogues are deeper, pricing is negotiated, payment terms are extended and the buyer is a procurement team rather than a consumer. Buyers split between a long tail of SMBs ordering on credit terms and large enterprise procurement organisations running through ERP-integrated punchout catalogues.
The sector spans wholesale and distribution platforms that move inventory from manufacturers to retailers, industrial and MRO marketplaces selling parts to factories and field-service teams, manufacturer direct portals, and the horizontal cross-border platforms like Alibaba.com that aggregate Chinese factory supply for global SMB buyers.
Revenue comes from take rates on transactional GMV, subscription fees paid by suppliers for visibility and listing tools, advertising on category and search pages, embedded payments and trade-credit float, and logistics and fulfilment fees on platform-managed inventory.

How B2B e-commerce companies monetize?
B2B e-commerce companies monetize through GMV take rates, supplier subscriptions and embedded trade credit.
Take rate on GMV
Commission on every transaction routed through the platform, typically 5-15% of order value. Standard model for Faire, Ankorstore and Alibaba.com on third-party orders.
Supplier subscriptions
Recurring fees paid by brands and suppliers for storefront tooling, premium placement and order-management software. Alibaba's Gold Supplier and Joor's brand subscriptions sit here.
Trade credit & payments
Net-60 buyer terms financed by the platform or a third party, with the platform earning a spread on the receivable or fee per transaction. Faire and Ankorstore built large credit books on this.
Advertising & promoted listings
Sponsored search and category-page ads sold to suppliers competing for buyer attention. Amazon Business runs the largest ad business in B2B; Alibaba.com generates a meaningful share of revenue here.
Logistics & fulfilment fees
Pick, pack, ship and warehouse fees on platform-managed inventory, plus cross-border freight and customs services. Material at Amazon Business and on Alibaba's logistics arm Cainiao.
Direct sales / 1P inventory
Platform buys inventory and sells it on its own balance sheet at a gross margin. The dominant model at most industrial distributors (Grainger, Fastenal) and a growing share of Amazon Business GMV.

B2B e-commerce market segments
B2B e-commerce spans wholesale and distribution marketplaces, industrial and MRO platforms and horizontal cross-border marketplaces.
Wholesale & distribution marketplaces
Platforms connecting brands to independent retailers and small businesses, replacing trade shows and rep-led wholesale. Faire dominates North America, Ankorstore leads Europe, Tundra (now wound down) was the failed third entrant. Key players: Faire, Ankorstore, Joor and NuOrder.
Industrial & MRO platforms
Catalogues for industrial maintenance, repair and operations buyers - fasteners, electrical, PPE, lab supplies and machine parts. Largely a hybrid of distributor 1P inventory and supplier 3P listings. Key players: Grainger, Fastenal, RS Group and MSC Industrial.
Horizontal cross-border marketplaces
Platforms aggregating manufacturer supply (mostly Chinese) for global SMB buyers sourcing private label, components and finished goods. Alibaba.com is the scale leader by an order of magnitude; Made-in-China and Global Sources sit in the long tail. Key players: Alibaba.com, Made-in-China, DHgate and Global Sources.
Vertical wholesale marketplaces
Category-specific platforms for fashion, food and beverage, electronic components, chemicals and pharmaceuticals where category-specific catalogue depth and compliance matter. Key players: Joor (fashion), Choco (food service), Knowde (chemicals) and Pharmarack (pharma).
Marketplace software & enablers
Platform-as-a-service infrastructure for retailers and distributors who want to operate their own marketplace rather than build from scratch. Powers the marketplace strategies of Walmart, Carrefour, Macy's and Best Buy. Key players: Mirakl, Marketplacer, Nautical Commerce and VTEX.
Procurement & spend platforms
Enterprise procurement networks where buyer ERPs connect to supplier catalogues via punchout, with invoicing, approval workflow and spend analytics layered on top. Key players: SAP Ariba, Coupa, Jaggaer and Ivalua.
Amazon Business & big-tech B2B
Vertically integrated B2B arms of consumer marketplaces, leaning on existing consumer logistics and ad infrastructure. Amazon Business reportedly crossed $35B in GMV in 2024 across 6M business customers. Key players: Amazon Business, Walmart Business, eBay Business Supply and JD Industrial.

Key B2B e-commerce KPIs to track
GMV, take rate, contribution margin per order and trade-credit loss rate are the metrics investors track in B2B e-commerce.
| KPI | Definition |
|---|---|
| GMV | Gross merchandise value transacted through the platform. The headline scale metric for any marketplace business. |
| Take rate | Net revenue as a percentage of GMV. B2B marketplaces typically sit at 8-15%, lower than consumer marketplaces but higher than wholesale distributors. |
| Active buyers | Businesses placing at least one order in the trailing 12 months. The buyer side is harder to acquire than the supplier side in most B2B categories. |
| Repeat order rate | Share of buyers placing more than one order in a window. B2B replenishment is the core unit-economics lever - a one-time buyer is rarely profitable after CAC. |
| Average order value | GMV per order. Wholesale AOVs sit in the $300-$2,000 range; industrial MRO baskets are typically lower-frequency but higher-value. |
| Contribution margin per order | Order revenue minus payment, logistics and credit-loss costs. Faire publicly discloses contribution margin as its key path-to-profitability metric. |
| Trade-credit loss rate | Bad-debt expense on net-term receivables. The hidden lever in B2B marketplaces that extend credit to small retailers. |
| Supplier retention | Share of brands continuing to list and ship through the platform year over year. Supplier churn is a leading indicator of the marketplace value proposition versus DTC and trade shows. |

Key B2B e-commerce market trends
Wholesale marketplace profitability resets, marketplace-as-a-service inside large retailers and trade-credit pressure are reshaping B2B e-commerce right now.
Wholesale marketplaces reset to profitability
Faire and Ankorstore both shifted from growth-at-all-costs to contribution-margin discipline in 2023-24. Faire cut roughly 20% of staff in early 2023, Ankorstore cut twice across 2023-24; both have published contribution-margin progress while keeping GMV growth in the high teens. Posted dated: March 2025.
Marketplace-as-a-service inside large retailers
Walmart, Carrefour, Macy's, Best Buy and Kroger have all launched 3P marketplace tiers on top of their 1P retail, mostly powered by Mirakl, VTEX or in-house stacks. The model lets retailers grow assortment without inventory risk and capture marketplace economics. Posted dated: January 2026.
Trade-credit losses biting wholesale platforms
Independent retailers ran into cash-flow pressure through 2023-24 as consumer demand softened and rent costs climbed. Faire tightened underwriting and reduced its average net-term limit; smaller wholesale platforms (Tundra, Abound) wound down or pivoted away from credit-led acquisition. Posted dated: November 2025.
Cross-border tension on Alibaba.com
US tariff escalation under the 2025 trade actions and de-minimis reform on direct-import shipments hit Alibaba.com's SMB importer base, which has historically relied on duty-free entry of small orders. Alibaba pushed harder into bonded-warehouse fulfilment to absorb the rule changes. Posted dated: April 2026.
AI buyer assistants in industrial procurement
Grainger, Fastenal and Amazon Business have all rolled out conversational procurement assistants in 2024-25 that handle reorders, substitutions and quote-comparison via chat. The early use case has been replacing inside-sales touchpoints on long-tail SKUs. Posted dated: February 2026.
Punchout consolidation in enterprise procurement
SAP Ariba, Coupa (Thoma Bravo-owned since 2023) and Jaggaer continue to consolidate the punchout-and-invoicing layer. The B2B marketplaces winning enterprise budget are the ones with native integrations into these networks rather than direct-portal-only access. Posted dated: October 2025.
