B2B digital commerce hits its stride: MSC Industrial, Carrier Enterprise, and Sherwin-Williams show how it's done

MSC Industrial Supply's ecommerce channel helped carry the company past $1 billion in Q3 net sales, according to reporting by Beth Duckett in Digital Commerce 360. That figure, reported in early July 2026, is notable less as a milestone for one distributor and more as a signal of how far digital ordering has penetrated the industrial supply chain. Companies that have spent the past few years debating whether to invest in B2B ecommerce infrastructure are now watching peers post nine-figure quarters and rethinking the calculus.

60% digital: Carrier Enterprise puts a number on the benchmark

Carrier Enterprise offered one of the most concrete data points in the B2B distribution space this quarter. The HVAC products distributor disclosed it now generates 60% of its sales through digital channels, according to Brian Warmoth's coverage in Digital Commerce 360. That figure is rare: most distributors discuss digital transformation in directional terms, not percentages. Carrier Enterprise's willingness to publish the number gives procurement and operations leaders at competing firms a real target to pressure-test against their own channel mix.

Reaching 60% digital in a sector historically dominated by rep relationships and phone orders requires more than a web storefront. It typically involves integrating ERP data with customer-facing ordering systems, training inside sales to redirect rather than intercept digital orders, and giving customers sufficient account-level visibility to self-serve on complex SKUs. The disclosure from Carrier Enterprise suggests those investments are paying off in measurable revenue shift.

Sherwin-Williams and the professional buyer experience

Sherwin-Williams moved in early July to integrate Square features into its workflows for professional customers, as reported by Kevin Williams in Digital Commerce 360. The partnership targets the contractor and trade professional segment, where billing, job-based purchasing, and payment reconciliation have historically created friction between a supplier's digital storefront and how a professional actually runs their business. Adding Square's invoicing and payment tooling directly into the pro customer experience is a concrete attempt to close that gap.

The move reflects a broader pattern: B2B sellers are no longer satisfied with a product catalog and a checkout flow. The competition has shifted to surrounding the buyer with financial and workflow tools that reduce the reason to switch suppliers. For procurement leaders evaluating preferred-supplier arrangements, the operational stickiness these integrations create is worth factoring into total cost of ownership conversations.

Vendors accelerate: Salesforce adds AI agents to B2B commerce

Salesforce released AI agents aimed at B2B ecommerce use cases in late June, per Digital Commerce 360 reporting by Abbas Haleem. The agents are designed to handle tasks typically managed by sales operations or inside sales teams: reorder management, quote generation, and account-level customer service. The release puts pressure on competing commerce and CRM platforms to match the capability or risk losing enterprise accounts that are actively evaluating where automation fits into their order management stack.

Forbes, citing compiled ecommerce research, notes that B2B ecommerce continues to outpace B2C in transaction volume globally, with the segment attracting sustained platform investment as a result. The Salesforce AI agent release is one visible instance of that investment. Operations leaders who have deferred AI capability assessments in their commerce stack should treat this as a prompt to revisit vendor roadmaps in the second half of 2026.

Acquisitions add distribution scale as the digital floor rises

Two acquisitions reported by Digital Commerce 360 in late June add context to the channel shift. Motorcar Parts of America acquired the Centric Parts brake brands, as covered by Abbas Haleem, expanding its catalog in the automotive aftermarket. Separately, QXO and TopBuild shareholders voted to approve their merger, reported by Brian Warmoth, combining a tech-forward distribution platform with one of the largest building products installers in the country. Both deals reflect a strategic logic that is becoming familiar: scale the addressable product set, then push fulfillment through digital channels where unit economics improve with volume.

FedEx, for its part, credited B2B growth as a factor in its Q4 revenue increase, according to Digital Commerce 360's coverage by Abbas Haleem. Logistics revenue tied to B2B ecommerce fulfillment is a downstream indicator that the order volumes industrial and distribution companies are reporting are moving through carrier networks at increasing rates. Supply chain leaders benchmarking carrier capacity and rates for the second half of 2026 should weigh that demand signal when negotiating contract terms.

What this means for your team

• Benchmark your digital channel mix against Carrier Enterprise's 60% figure. If your organization is below 40%, identify which customer segments are still calling in orders and what friction is preventing self-service adoption.
• Evaluate whether your preferred B2B suppliers are integrating financial workflow tools such as invoicing, job-based billing, or payment reconciliation into their platforms, as Sherwin-Williams has done with Square. These integrations affect total cost of service, not just unit price.
• Audit your commerce platform vendor's AI agent roadmap before the next contract renewal. Salesforce's mid-2026 release sets a capability expectation; if your current platform lacks a credible answer, that is a negotiating point.
• For procurement teams that source from distributors undergoing M&A, confirm that catalog coverage, pricing tiers, and EDI or API connections will remain stable post-close. The Motorcar Parts and QXO-TopBuild deals are reminders that distributor consolidation can disrupt established ordering workflows.
