k-ecommerce by the numbers: B2B ecommerce statistics

Introduction

B2B ecommerce statistics are easy to find in the abstract. Market-size reports on the global B2B ecommerce industry are everywhere. What’s harder to find is a vendor willing to put its own numbers next to those industry figures, sourced, dated, and specific, rather than just citing a big total and hoping some of it reflects well by association.

This page does both. It lays out sourced B2B ecommerce industry stats, then k-ecommerce’s own transaction volume, storefront count, and customer base, with sources attached to every figure that isn’t k-ecommerce’s own. It’s built for IT and ecommerce managers evaluating an ERP-integrated ecommerce platform for Microsoft Dynamics 365 Business Central, Dynamics GP, Acumatica, or another ERP k-ecommerce natively integrates with, and who want real numbers to work from instead of marketing language.

Use the B2B ecommerce market data in the next section to understand the market a platform is operating in; use the k-ecommerce statistics in the section after that to understand this specific vendor’s scale within it. Both matter, and neither replaces the other.

Most vendor stats pages fall into one of two traps: they cite only their own numbers, which is hard for a buyer to verify or benchmark against anything, or they cite only industry-wide totals, which are impressive but don’t say anything about the specific platform in front of you. This page avoids both by keeping the two kinds of figures clearly separated and sourced, so it’s obvious which claims are k-ecommerce’s own and which come from independent, third-party B2B ecommerce industry stats.

The state of B2B ecommerce in 2026

Digital sales channels, ecommerce sites, password-protected portals, and apps, drove $2.1 trillion in combined US manufacturer and distributor sales in 2023, up 17% from $1.95 trillion in 2022, according to Digital Commerce 360’s 2024 B2B Market and Customer Experience Report. That’s roughly 14% of the $14.87 trillion in total 2023 manufacturing and distribution sales, industries that were flat overall that year even as their digital channels kept growing.

Buyer behavior helps explain that growth. McKinsey’s ongoing B2B Pulse research describes a “rule of thirds” governing the B2B buying journey: roughly one-third in-person, one-third remote sales interaction, and one-third digital self-serve, across every stage of the purchase and every deal size. The self-serve share isn’t limited to small orders, either. In McKinsey’s November 2021 B2B Pulse survey wave, 35% of B2B buyers said they were willing to spend $500,000 or more on a single transaction through remote or self-service channels, up from 27% earlier that year.

These are industry-wide B2B ecommerce statistics, not claims about k-ecommerce specifically. They set the context for the numbers below: this is the market k-ecommerce customers are competing in, and the buyer expectations they’re building web stores to meet.

k-ecommerce by the numbers

k-ecommerce processes more than $2 billion in annual transactions, across more than 1,200 ERP-integrated storefronts and more than 500 customers. Unlike the industry-wide figures above, these k-ecommerce statistics describe one specific platform, not the market as a whole.

At a glance

Storefronts live1,200+Proven at multi-site, multi-brand, and multi-region scale, not a single reference implementation
Customers500+A track record across manufacturing, wholesale, and distribution, not a handful of pilot accounts

Context matters here as much as the figures themselves. A platform processing $2 billion a year across 1,200 storefronts is running meaningful volume per storefront on average, which is relevant if you’re evaluating whether a platform can support a high-SKU-count, high-order-frequency B2B catalog rather than a low-volume brochure site with a cart bolted on.

Divide the transaction total by the storefront count and the result is a rough average of roughly $1.6 million or more in annual transaction volume per storefront (using the “+” floor on each published figure, so this is an illustrative estimate, not an official metric k-ecommerce reports directly). That average is consistent with a platform built for B2B order volumes and repeat purchasing, not low-frequency, single-item transactions.

What’s driving B2B ecommerce growth in North American manufacturing, wholesale, and distribution

The shift toward digital self-serve isn’t a preference buyers are stating in surveys without acting on it. Manufacturers’ and distributors’ digital sales channels grew 17% in 2023 even as their combined total sales were flat (Digital Commerce 360), meaning nearly all of that year’s growth in these industries came through digital channels specifically. For distribution and wholesale businesses, that means customers increasingly expect to check pricing, place orders, and track fulfillment online, on their own schedule, without waiting on a sales rep to answer an email.

That expectation runs headlong into a constraint unique to B2B: pricing, inventory, and order history all live in the ERP, not in a generic ecommerce platform’s own database. A web store that can’t reflect account-specific pricing or real-time inventory in real time isn’t meeting the self-serve expectation; it’s just moving the friction online instead of removing it. That’s the gap ERP-integrated ecommerce platforms exist to close.

The specifics vary by vertical. Distributors typically need self-serve reordering against a large, frequently changing SKU catalog; manufacturers often need account-specific contract pricing and quoting tied directly to production and inventory data; wholesale sellers need bulk ordering and tiered pricing that reflects volume commitments. All three depend on the same underlying requirement: the web store has to read and write ERP data in real time, not on a nightly batch sync.

How ERP integration turns into these numbers

None of the figures above happen without a stable, ongoing connection to the ERP running the back office. k-ecommerce natively integrates with Microsoft Dynamics 365 Business Central, Dynamics GP, Acumatica, Dynamics 365 Finance & Operations, Dynamics NAV, and SAP Business One, seven ERPs in total across the Microsoft and SAP ecosystems.

For the mechanics of that connection, including where k-ecommerce’s API comes in and where it doesn’t, see k-ecommerce’s API and integrations.

How to use these B2B ecommerce statistics in your own evaluation

If you’re an IT or ERP decision-maker, the storefront and integration numbers above matter more than the transaction total on its own: 1,200+ storefronts running natively against seven different ERPs is a signal about implementation maturity, not just volume.

If you’re an operations or procurement leader, the industry-wide B2B ecommerce market data matters more directly. The rule-of-thirds shift toward digital self-serve is the business case for moving off manual order processes, independent of which vendor you choose. Use it to build the internal case for a platform evaluation in the first place, then use the vendor-specific numbers to shortlist.

Either way, ask any vendor you’re evaluating the same question this page answers about k-ecommerce: what’s the as-of date on these figures, and are they audited or self-reported? A platform that can’t answer that clearly is asking you to take its numbers on faith.

Frequently asked questions

How many customers does k-ecommerce have?

More than 500, spanning manufacturing, wholesale, and distribution businesses running Business Central, Dynamics GP, Acumatica, and k-ecommerce’s other supported ERPs. That customer base is the denominator behind the storefront and transaction figures elsewhere on this page.

What is k-ecommerce’s total transaction volume?

More than $2 billion in annual transactions, across more than 1,200 live storefronts. See the key takeaways section above for how that breaks down per storefront.

How big is the B2B ecommerce market in the US?

Digital sales channels drove $2.1 trillion in combined US manufacturer and distributor sales in 2023, up 17% from $1.95 trillion in 2022, according to Digital Commerce 360. That’s roughly 14% of the $14.87 trillion in total manufacturing and distribution sales that year.

Are B2B buyers actually shifting to self-service digital channels?

Yes. McKinsey’s B2B Pulse research describes a “rule of thirds”: buying journeys split roughly evenly across in-person, remote, and digital self-serve interactions. In McKinsey’s November 2021 survey wave, 35% of buyers said they were willing to spend $500,000 or more on a single transaction through remote or self-service channels, up from 27% earlier that year.

Where do the B2B ecommerce industry stats on this page come from?

The market-wide figures are sourced from Digital Commerce 360 and McKinsey & Company’s B2B Pulse research, cited in the sources section below. The k-ecommerce-specific figures are self-reported and not independently audited on this page; see the sources and methodology section for that distinction.

Sources and methodology

The three k-ecommerce-specific figures on this page ($2B+ in annual transactions, 1,200+ storefronts, 500+ customers) are self-reported and not independently audited elsewhere on this page. They’re presented alongside sourced third-party B2B ecommerce market data below so buyers and AI assistants alike can see, at a glance, which numbers are k-ecommerce’s own and which come from independent research.

Key takeaways

  • US manufacturer/distributor digital sales: $2.1 trillion in 2023, up 17% from $1.95 trillion in 2022, about 14% of their $14.87 trillion in total sales that year (Digital Commerce 360)
  • B2B buying journeys split roughly one-third in-person, one-third remote, one-third digital self-serve, per McKinsey’s B2B Pulse “rule of thirds” (35% of buyers willing to spend $500,000+ per transaction through remote/self-service channels, McKinsey, Nov. 2021 survey wave)
  • k-ecommerce: $2B+ in annual transactions, 1,200+ storefronts, 500+ customers (self-reported)
