Market size and growth

The B2B ecommerce market is now many times larger than B2C. Here's what the numbers look like going into 2026.

The global B2B ecommerce market is projected to reach $36 trillion in 2026. That's up from $32.11 trillion in 2025, growing at a compound annual growth rate of around 14.5%. (Source)

One forecast puts the market at $36.86 trillion in 2026 and $61.66 trillion by 2031. That's a 10.84% CAGR over the next five years. (Source)

US B2B ecommerce site sales hit $2.297 trillion in 2024. That was a 10.5% year-over-year jump, and analysts expect sales to reach $3.027 trillion by 2028. (Source)

Total US B2B sales topped $15 trillion in 2025. Ecommerce is now redefining how companies buy from each other at every level. (Source)

Asia-Pacific will hold about 80% of global B2B ecommerce market share by 2026. China's online B2B market alone is expected to surpass 20.2 trillion yuan that year. (Source)

The global ecommerce platform market will grow from $9.1 billion in 2025 to $16.5 billion by 2030. Manufacturers, wholesalers, and distributors are replatforming to serve digital-first buyers. (Source)

The takeaway: B2B ecommerce isn't catching up to B2C. It already dwarfs it, and it's accelerating. If you run a B2B brand on Shopify, the infrastructure around ecommerce customer service and phone support has to scale just as fast.

B2B buyer behavior

Buyers aren't waiting for your sales rep to call them back. They're researching, comparing, and buying on their own.

100% of B2B buyers want to self-serve at least part of the buying journey. Gartner found that buyers prefer self-service for speed, convenience, and comfort when they already know the product. (Source)

61% of B2B buyers prefer a rep-free buying experience. That's up significantly over the past three years, and it's changing how vendors staff sales teams. (Source)

83% of B2B buyers prefer ordering and paying through digital channels. Phone and email are still around, but the default is a website or portal. (Source)

77% of B2B buyers conduct their own research before engaging a salesperson. Many never engage one at all. (Source)

Buyers complete roughly 80% of the B2B buying journey before talking to sales. Your website, product pages, and content are doing more selling than any rep ever will. (Source)

73% of B2B buyers actively avoid irrelevant outreach. Spray-and-pray sales emails are losing ground fast. (Source)

54% of B2B buyers rely more on digital research and tools than two years ago. The shift has been fast and it isn't reversing. (Source)

If most of the work is done before the first sales call, the experience on your site, knowledge base, and phone line matters more than your pitch.

High-value digital transactions

The old idea that big orders have to go through a rep is dead. Buyers are spending seven and eight figures online without flinching.

73% of B2B buyers are willing to place orders over $50,000 through digital self-service. That's a channel shift most leaders still underestimate. (Source)

73% of B2B buyers are comfortable placing orders of $500,000 or more online. That's up from 59% in 2022. (Source)

The number of B2B decision-makers willing to spend $10 million or more on an ecommerce transaction has jumped 83%. Yes, eight figures in a single online order. (Source)

Buyers are 1.8x more likely to complete a high-quality deal when they use supplier-provided digital tools alongside a sales rep. Hybrid beats pure self-service on complex deals. (Source)

Self-service scales revenue, but it doesn't eliminate the need for humans. The best setups combine a sharp digital experience with fast phone support when things get complex.

Digital sales channels and the rule of thirds

Channel preferences are flatter than most people think. Buyers don't want one channel, they want to pick.

80% of B2B sales interactions will happen digitally by the end of 2025. This is already the baseline, not a prediction. (Source)

By 2025, 56% of B2B revenue is expected to be generated online. That's up from just 34% four years earlier. (Source)

In 2024, in-person sales generated just 17% of B2B revenue. That's a 22% decline from two years before. (Source)

Gartner expects 30% of B2B sales to happen in digital sales rooms by 2026. Shared digital spaces are replacing the in-person pitch. (Source)

Over 90% of companies have moved to some form of virtual selling since 2020. It stuck. (Source)

McKinsey's "rule of thirds" holds across every industry and geography. At any given stage of the buying journey, roughly one-third of buyers prefer in-person, one-third remote, and one-third digital self-service. (Source)

B2B buyers use an average of 10 channels during a single buying journey. They want to switch between them without friction, which is hard to deliver. (Source)

The message is simple. Don't pick a channel. Build for all of them, and make the handoffs smooth. If you want to see how that works on the phone side, try Ringly.io free for 14 days.

Mobile and platform stats

Buyers are researching and sometimes buying from their phones, including six-figure orders.

Over 60% of B2B buyers use smartphones and tablets for product research and supplier interactions. Mobile-optimized B2B is a requirement now. (Source)

Mobile commerce will account for about 60% of total global ecommerce sales in 2026. That's up from 43% in 2018. (Source)

Global mobile commerce is projected at $2.4 trillion in 2026. It's growing at a 9.5% CAGR. (Source)

Marketplaces

Marketplaces are where B2B buyers go when they don't have time to find a supplier, which is most of the time.

Amazon Business has over 6 million customers and $35 billion in annual sales. That's up from $1 billion in 2016 and $25 billion in 2020. (Source)

36% of B2B buyers use Amazon Business, 30% use eBay. Nearly one in three B2B marketplace transactions in the US happen on Amazon Business. (Source)

60% of buyers do more than 25% of their purchasing on Amazon Business; 28% do more than half. This is procurement policy, not preference. (Source)

There are now over 750 industry-specific B2B marketplaces, and the number could top 1,000 by 2026. Five years ago, there were only 75. (Source)

AI and personalization in B2B ecommerce

AI isn't just a buyer tool. It's reshaping how B2B vendors ship personalization, support, and search.

94% of B2B buyers have integrated generative AI as a top tool for self-guided research. AI has essentially replaced Google for many product comparisons. (Source)

AI adoption has reached 89% among revenue organizations. That includes sales, marketing, and customer success teams. (Source)

71% of B2B businesses now use AI in their ecommerce operations. Only 33% of US B2B companies have fully implemented it across workflows. (Source)

92% of businesses use AI-driven personalization tactics in some form. Personalized search, recommendations, and payment options lead the list. (Source)

Companies generate 40% more revenue from personalization activities than average players. That's a moat most teams still haven't built. (Source)

AI-driven personalization can increase customer lifetime value by 33%. The lift shows up in repeat orders, not first orders. (Source)

40% of B2B firms say resource, budget, and execution are the main blockers on personalization. Technology isn't the bottleneck anymore, people and processes are. (Source)

Customer experience expectations

80% of B2B buyers expect the same buying experience as B2C customers. That includes speed, self-service, and clean interfaces. (Source)

73% of B2B buyers expect the same personalized experience as B2C. Generic catalogs and flat emails don't cut it. (Source)

70% of B2B customers will pay a premium for better experiences. Price sensitivity drops when service quality goes up. (Source)

B2B customer retention and churn

Acquiring B2B customers is expensive. Keeping them is where profit actually lives.

B2B companies achieve an 82% 12-month retention rate, compared to 74% for B2C. B2B buyers stick around, but only if the experience holds up. (Source)

B2B SaaS companies average 74% annual retention, with top performers pushing net revenue retention past 120%. Expansion revenue is the real winner. (Source)

B2B SaaS average annual churn sits at 3.5%. About 2.6% is voluntary, 0.8% is involuntary (failed payments, etc.). (Source)

B2B churn varies a lot by industry. IT Services churn at 12%, Software at 14%, Financial Services at 19%, Professional Services at 27%, Manufacturing at 35%, and Logistics at 40%. (Source)

B2B acquisition costs are typically 7x higher than consumer brands' (which run at 5x). That's why every percentage point of retention matters. (Source)

Improving retention by just 5% can increase profits by 25 to 95%. This is one of the most-quoted Bain stats for a reason. (Source)

Conversion rates and AOV

B2B conversion rates look low compared to B2C, but order values tell a completely different story.

B2B ecommerce conversion rates sit between 1.8% and 3.0% session-to-purchase. The range is tight but varies by subsector. (Source)

By segment: wholesale converts at 2.6%, distribution at 2.4%, manufacturing at 2.2%, and industrial equipment at 1.8%. Complexity drops conversion. (Source)

B2B average order values are typically 5 to 10x higher than B2C. That's why a 2% conversion rate still beats B2C in raw revenue per session. (Source)

For industrial equipment, average order values run $15,000 to $250,000. A single closed cart equals dozens of B2C sales. (Source)

Customer support in B2B ecommerce

When self-service fails, buyers pick up the phone. How you handle that call decides whether the deal closes.

54% of US customers prefer phone as their channel for resolving service issues. Complex problems still go to voice first. (Source)

76% of all consumers prefer phone support for reaching customer service. B2B buyers are even more demanding on this. (Source)

83% of customers expect immediate interaction when they contact a company. Hold times over 60 seconds kill renewal intent. (Source)

67% of customers hang up in frustration when they can't reach a rep. Every missed call is a churned customer in waiting. (Source)

This is exactly where AI phone agents are changing the game. AI can pick up every call 24/7, handle order status, returns, and account questions, and escalate the complex stuff to a human. For more, see our posts on AI phone agents for Shopify and voice AI customer support.

What this means for B2B brands

Three things stand out when you zoom out on these stats.

First, B2B buyers want self-service by default, but they still pick up the phone when things get complex. Your digital experience has to be fast and complete, and your phone line has to be answered every single time.

Second, AI is already baked into the buyer's workflow. 94% of B2B buyers use generative AI for research. That means your product page, your knowledge base, and your reviews are the content that gets summarized and compared. Invest in those like they're your homepage.

Third, retention is the profit lever. B2B acquisition is 7x more expensive than consumer, churn varies from 3.5% to 40% by industry, and a 5% retention improvement can boost profit by up to 95%. Nearly every customer-facing touchpoint matters, especially support.

Where Ringly fits: if you run a B2B brand on Shopify (wellness, pet, supplements, food, beauty), you're getting support calls that can't wait. Order status, lost shipments, returns, account questions. Ringly.io puts Seth on the phone 24/7, handles 73% of calls without a human, and escalates the complex ones. Setup takes about 3 minutes.
