Why B2B e-commerce does not grow despite investments in marketing

In many companies, the development of B2B e-commerce begins with investments in marketing. Organizations increase advertising budgets, launch campaigns in Google Ads and LinkedIn, invest in SEO, and develop content marketing activities. Website traffic begins to grow, the number of inquiries from customers increases, and marketing teams report better and better results in terms of visibility and user acquisition.

At the same time, sales often do not grow at the pace that was expected. Conversion rates remain low, and a significant portion of customers still place orders outside the e-commerce platform – by email, phone, or through direct contact with a sales representative.

In such situations, the conclusion often appears that marketing is not effective enough. In reality, however, the problem rarely concerns marketing alone. In B2B e-commerce, the barrier to growth is much more often the architecture of sales itself and the way the purchasing process has been designed.

Marketing can increase the visibility of an offer and attract potential customers to the sales platform. However, it cannot solve problems resulting from an unclear catalog structure, a complicated ordering process, or the lack of system integrations.

This is why companies that focus exclusively on increasing marketing budgets often reach a point where further investments in advertising no longer generate proportional sales growth.

Marketing increases traffic but does not solve sales problems

In e-commerce, marketing and sales are closely connected but serve different functions. Marketing is responsible for generating traffic, building interest in the company’s offer, and attracting new customers to the sales platform.

Sales begins only when the user reaches the platform and decides to place an order.

In the B2B model, this moment is much more complex than in retail. Customers expect access to individual pricing, order history, purchasing lists, negotiated discounts, and tools that allow them to place recurring orders quickly.

If the sales platform does not support such scenarios, even large volumes of traffic generated by marketing will not translate into sales growth.

In practice, this means that marketing can bring the customer to the platform, but the platform itself must enable the customer to move smoothly through the purchasing process.

Misalignment between the e-commerce platform and the B2B model

One of the most common reasons for slow sales growth is that many e-commerce platforms were originally designed primarily for the B2C model.

In retail, the purchasing process is usually simple. A customer browses the offer, adds a product to the cart, and completes payment. In B2B, the process may include many additional elements.

Customers may operate within organizational structures where different people are responsible for different stages of the purchasing process. One person may create a list of products, another may approve the order, and another may be responsible for payment and settlement.

The e-commerce platform should be able to support such scenarios by enabling role management, approval processes, and budget limits.

If the platform is not prepared to support these processes, customers very often return to traditional sales channels.

Unclear product catalog structure

In many companies, the product catalog is structured in a way that reflects the internal organization of the company rather than the way customers search for products.

Products are grouped according to technical or production categories that are understandable for the manufacturer but not necessarily for the customer. As a result, customers often have difficulty finding the right products.

Another problem is the quality of product data. Product descriptions may be incomplete, technical parameters may not be standardized, and images or marketing materials may not always be available.

In such situations, customers often need assistance from a sales representative to place an order. The e-commerce platform stops being an independent sales channel and becomes only a product catalog.

For this reason, more and more organizations decide to implement PIM systems and reorganize their catalog structures based on real customer needs.

Lack of integration with operational systems

In the B2B environment, an e-commerce platform rarely functions as a standalone sales tool. It must cooperate with ERP systems, warehouse management systems, and tools used for product information management.

If the sales platform is not integrated with these systems, many operational problems appear.

Customers may see outdated prices or product availability. Order history may be incomplete, and order fulfillment may require manual intervention by company employees.

Modern e-commerce platforms such as Shopware were designed with integration with ERP, PIM, and WMS systems in mind. Thanks to an API-first architecture, it is possible to build an environment in which data flows between systems in a consistent and predictable way.

Such an approach significantly reduces the number of manual processes and allows the e-commerce platform to take over a larger share of sales.

Lack of personalization of the commercial relationship

Commercial relationships in B2B sales are rarely identical for all customers. Companies often negotiate individual prices, discounts, and delivery conditions.

If the e-commerce platform is not able to reflect these relationships, customers do not perceive it as a real purchasing tool.

A customer logging into the platform should see an offer tailored to their commercial relationship with the supplier. They should have access to individual prices, order history, and tools that allow them to repeat previous purchases quickly.

Platforms such as Shopware enable the management of individual product catalogs and dynamic pricing policies.

Thanks to this, the e-commerce platform can reflect real business relationships between companies.

Conflict between sales and marketing teams

In many organizations, marketing and sales function as two separate areas of responsibility.

The marketing team focuses on generating traffic and acquiring new customers, while the sales team is responsible for completing orders and maintaining customer relationships.

If the e-commerce platform does not support sales processes, tension arises between these teams. Marketing generates traffic, but sales is not able to convert it into orders.

In such situations, marketing begins to be perceived as a cost rather than as a growth driver.

E-commerce as part of the sales architecture

The development of B2B e-commerce requires looking at digital sales in a broader organizational context.

The sales platform should be integrated with ERP systems, support customer purchasing processes, and enable scalable management of commercial relationships.

Only in such an environment can marketing activities fully translate into sales growth.

At CREHLER, we often observe that companies investing in marketing without simultaneously modernizing their e-commerce architecture achieve limited sales results.

Platforms such as Shopware make it possible to build a sales environment in which marketing, purchasing processes, and system integrations create one coherent ecosystem.

This approach is what allows traffic generated by marketing to be transformed into real sales growth in the B2B model.
