Everything You Need to Know About B2B E-Commerce

In France, B2B e-commerce is estimated to generate nearly €700 billion in annual revenue. In addition, around 40% of companies have already partially or fully digitized their B2B purchasing, and 71% plan to keep investing. But launching or improving your B2B eCommerce site comes with challenges. In this comprehensive guide, we’ll walk you through everything you need to know about B2B e-commerce.

B2B e-commerce market by the numbers  

The B2B e-commerce market is growing exponentially:  

• Worldwide, the market exceeds $10 trillion.  

• In Europe, online B2B sales could reach $1.8 trillion in 2025.  

• 89% of B2B buyers use the internet in their research process.  

• On average, a B2B buyer performs 12 searches before interacting with a brand’s website.  

• According to Gartner, 80% of B2B sales interactions will happen digitally by 2025.

What is B2B eCommerce?

B2B e-commerce refers to all online sales transactions for products or services between two companies or business entities. This model differs from B2C e-commerce in the nature and volume of transactions. In B2B, purchases are often made in bulk, on a recurring basis, for high amounts, and involve multiple decision-makers. B2B commercial exchanges are also generally more complex and more customized to meet each customer’s specific needs:

• Tailored payment terms.

• Negotiated volume-based pricing.

• Master agreements.

A B2B eCommerce platform is a digital solution for managing these business-to-business transactions. It gives sellers a digital channel to market their products and buyers an efficient way to purchase online. By automating administrative tasks and centralizing product information on online product pages, companies save time and gain visibility.

The goal of B2B e-commerce is to sell more, faster, and further.

What are the differences between B2B and B2C e-commerce?  

Complexity and length of the buying process  

In B2B, buying decisions often involve multiple stakeholders (between 5 and 10), approval committees, and negotiations. The sales cycle can stretch from 6 to 12 months. In B2C, transactions are usually closed in just a few days.  

Buying motivations  

B2B buyers base their decisions on a rational analysis of long-term risks and benefits: time savings, cost reduction, and profit growth. B2C purchases are more influenced by emotional factors and immediate personal needs.  

Transaction volume and value  

B2B transactions usually involve large volumes and high amounts, while B2C covers low-value individual purchases made in large numbers.  

Commercial relationship

B2B favors long-term, personalized customer relationships. B2C relies on more one-off, standardized interactions.

Who are the buyers and sellers in B2B eCommerce?

Online B2B commerce involves three types of business players:

1. Manufacturers

Manufacturers produce goods at industrial scale (raw materials, manufactured products, technical components). In the context of B2B e-commerce, they can launch their own B2B online store to sell directly to business buyers. This gives them greater control over their brand image and helps them reach a broader customer base.

For example, a manufacturer of industrial spare parts can set up a B2B e-commerce site. Customers can then order parts directly, check real-time stock levels, and get customized pricing based on volume.

2. Wholesalers

Wholesalers are intermediaries specialized in selling goods in bulk. They buy products in very large quantities and resell them, by batch or pallet, to business customers. The benefit of buying wholesale is access to volume-based pricing.

Sectors such as food service, healthcare, and construction rely on wholesalers for supply. By adopting an online platform, wholesalers can digitize order capture and automate many tasks:

• Up-to-date online catalog.

• Inventory and order management.

• Quote generation…

A restaurant customer can log back in to reorder a standard basket in just a few clicks instead of faxing an order manually. The benefits are twofold: a better buying experience for customers and a stronger wholesale offer that becomes more visible and attractive. An e-commerce site also makes it easy to present product ranges clearly, with photos and detailed descriptions.

3. Distributors

Distributors are commercial partners who ensure products reach the final market. In a traditional network, a distributor buys products from manufacturers or wholesalers and resells them to end customers (business users or consumers). They often act as the online or physical showcase for the brands they distribute.

In B2B e-commerce, distributors are valuable allies for manufacturers. By listing those products on their e-commerce platform, they increase manufacturers’ visibility. It’s a win-win: the manufacturer sells more through the distributor’s network, and the distributor expands its offer, attracting more customers to its platform.

In the digital age, some distributors even launch their own B2B marketplace open to multiple sellers, becoming marketplace operators. Amazon Business and Alibaba connect thousands of B2B sellers with buyers around the world.

What are the different types of B2B platforms?

Business-to-business e-commerce can take several forms, with platforms designed for specific use cases:

The e-commerce platform

This is a classic B2B e-commerce site, set up by a seller to offer its products online to business buyers. It includes eCommerce features for managing the product catalog, cart, order, and online payment. The site usually offers tools to customize pricing by customer or volume, manage multiple user accounts, and display tailored content.

Online procurement

E-procurement is designed from the buyer’s perspective. The platform’s main purpose is to streamline the customer company’s purchasing process. Its features focus on supplier selection, quote requests, and issuing electronic purchase orders. This system ensures compliance with negotiated contracts and speeds up purchasing by eliminating paper-based exchanges.

The marketplace

A B2B marketplace is a platform where a third-party operator connects multiple business sellers and buyers. The operator sets the rules, ensures the marketplace runs smoothly, and can offer additional services. This model creates a very broad offer and competition between suppliers.

• For buyers, the advantage is having a wide choice.

• For sellers, it means access to a larger audience.

The choice of your B2B eCommerce platform is a strategic decision that depends on your goals.

What is an “open” vs. “closed” B2B eCommerce platform?

There are two main types of B2B websites, depending on access:

Open B2B eCommerce sites:

An open B2B e-commerce site is accessible to anyone for initial browsing. Its pages can be viewed freely and are indexed by search engines, allowing potential customers to discover the offer through Google. However, completing a purchase often requires registration as a business customer. An open site combines maximum visibility with purchase-time personalization to acquire new customers through organic search.

Closed B2B eCommerce sites:

A closed B2B e-commerce site operates as a private network. Full access requires prior authentication. The content is not publicly visible or indexed by Google. Only approved business customers can log in and place orders.

This model helps protect sensitive information (specific pricing, exclusive references, commercial terms). The closed site secures transactions by limiting them to known partners and supports long-term loyalty.

Why invest in a B2B eCommerce solution?

Moving to online commerce has become essential for B2B companies that want to stay competitive. Buying behavior has changed. In fact, consumers (B2C) have gotten used to buying online, benefiting from seamless, fast, and personalized experiences.

B2B buyers now expect the same convenience and responsiveness when placing orders for their business. According to Deloitte, 81% of business buyers want access to more self-service tools. They prefer to search and order independently, without having to call a sales rep every time.

In addition, if a supplier doesn’t offer online ordering, buyers will move on to a more digitally advanced competitor. A 2024 survey of 500 B2B buyers in Europe shows that 71% make more than half of their business purchases online.

The quality of the online experience matters just as much. More than 80% of B2B buyers have already abandoned an online order because of a poor user experience.

Finally, recent economic and health crises, along with supply chain uncertainty, have shown how important agility and connectivity are. B2B companies with an e-commerce channel were able to keep selling despite restrictions. Digital commerce ensures business continuity and opens the door to new markets without geographic boundaries.

The main benefits for businesses:

Adapting to the specifics of B2B commerce

B2B e-commerce makes it possible to address the specific needs of business-to-business trade. Buyers often place large orders with demanding technical requirements. The process also involves multiple decision-makers.

A B2B e-commerce solution centralizes all essential information through detailed product pages and can manage multiple user levels. The platform can also adjust delivery times, offer installment payments, and display customer-specific pricing.

Data capture

A B2B e-commerce platform generates a wealth of data on buying behavior. By tracking the metrics, you can analyze sales performance, identify which products generate the most interest, which ones sell less, and what the average basket size is. This information helps you make smarter strategic decisions. Customer relationship management is also easier when paired with e-commerce: the seller can track order history and automate targeted follow-ups.

Customer acquisition

B2B e-commerce is a powerful tool for acquiring new customers beyond your existing base. B2B buyers search online for new potential suppliers. Having a well-ranked B2B e-commerce site gives you 24/7 visibility worldwide. Digital commerce also opens the door to international expansion. More than 28% of French e-commerce sites already sell internationally across more than 10 countries.

Creating a seamless customer experience

Digital tools make it possible to build a smooth, personalized online buying experience:

• You can simplify the ordering journey by letting customers duplicate a previous order in one click.

• A site can display a personalized online catalog for each customer, along with customized pricing.

This high-quality experience leads to greater satisfaction and strengthens the commercial relationship.

Increasing sales

A B2B e-commerce site can increase sales by creating more selling opportunities and selling more to each customer. The platform can automatically recommend relevant products (cross-sells and upsells). These personalized recommendations make the buying process easier while increasing average order value.

What are the challenges of B2B eCommerce?

One key challenge is integrating the platform with existing systems (ERP, CRM, logistics system). This workflow integration is important to ensure real-time operations management.

A second challenge is security and reliability. It is essential to secure online payments and protect customer data. The platform must be robust, highly available, and perform well.

The third challenge concerns people and sales organization. You need to:

• Realign the role of the sales team in this new omnichannel model.

• Train staff on digital tools.

• Support customers through the change.

Finally, you also need to keep an eye on emerging B2B eCommerce trends:

• AI and eCommerce are converging (machine learning-powered recommendations, smart chatbots)

• The rise of mobile commerce is forcing companies to optimize the smartphone experience

Each B2B eCommerce trend brings its share of challenges, but also opportunities.
