B2B e-commerce: 5 critical errors to avoid for online sales success

Cover for the article B2B e-commerce: 5 critical errors to avoid for online sales success.

B2B commerce is entering a new era. Boosted by digitalization, new buyer expectations, and the transformation of usage patterns, B2B e-commerce is no longer just an ancillary channel: it has become a lever for growth, customer loyalty, and operational efficiency. But beware: selling online in B2B cannot be improvised. What works in B2C is not enough, and many companies underestimate the complexity and opportunities of this channel.

Sales cycles are longer, amounts are higher, and decision-makers are multiple. In this demanding context, certain mistakes can be costly and permanently compromise your commercial efforts. We share 5 common mistakes to avoid to maximize your B2B online sales.

Error n°1 : Neglecting customer journey personalization

Each of your B2B prospects is different, and treating them all the same way is a mistake. Many B2B companies think it’s enough to “copy-paste” a B2C strategy to succeed in their digital transformation. Unlike B2C where purchases are often impulsive and individual, B2B involves complex decision-making processes with multiple stakeholders having distinct needs.

B2B clients seek personalized solutions that meet their needs. However, professional buyers’ expectations are very specific: they need advanced features, special commercial conditions, integrations with internal tools (ERP, CRM, etc.), and fine-grained user rights management. A generic approach can give the impression that you don’t understand their challenges, which can push them to turn to your competitors.

In a B2B environment, a technical director doesn’t seek the same information as a financial director or a purchasing manager. The first is interested in technical specifications and integration, the second in return on investment and costs, while the third focuses on contractual conditions and supplier reliability.

Offering a single journey amounts to diluting your message and losing your prospects’ attention at crucial moments in the buying process. We recommend developing personalized journeys based on well-constructed personas and their industries or sectors of activity. The behavioral data you can collect on each user will allow you to adapt the content you present to them.

For example, if a visitor mainly consults your technical pages, you can direct them toward case studies and documentation rather than generic content. This approach allows you to adapt not only the content but also the level of detail and the type of call-to-action offered.

Erreur n°2 : Sous-estimer l’importance de la preuve sociale

B2B fundamentally relies on trust, and this trust is more difficult to establish in a purely digital environment. Your prospects often invest significant amounts and engage their professional responsibility in their purchasing decisions. They need to feel confident before making a purchase, especially when it involves large amounts. This mistrust is amplified by the absence of human contact in the early stages of the buying process.

You must highlight tangible elements that prove your expertise and reliability to retain your prospects. Unlike B2C, generic testimonials like “Great service!” have no impact in B2B. Your prospects need concrete and measurable proof of your ability to meet their demands.

We recommend highlighting your certifications, partnerships, and client references. The idea is to create content that demonstrates your expertise, technical mastery, and understanding of sector challenges, with concrete examples (quantified data, testimonials about the evolution of specific KPIs).

Moreover, the notion of trust also involves optimizing your processes. Your e-commerce site should not be an isolated silo. Today, too many companies launch an e-commerce platform without properly interfacing it with their ERP, PIM, CRM or logistics solution. The result is prohibitive: stock errors, duplicates, slowdowns, and a truly degraded customer experience.

Concretely, if a customer places an order on your site and the stock wasn’t up to date, they will receive a follow-up and credit by email for an undeliverable product. They will be frustrated and you will have lost their trust.

Because yes, the heart of a B2B e-commerce site is its catalog. And in many cases, it’s also its Achilles’ heel. Too many projects are slowed down by incomplete, poorly categorized, obsolete product sheets, or transmitted in Excel for 15 years without clear nomenclature.

In B2B, a buyer needs precise data to place an order: dimensions, standards, compatibilities, quantity pricing, stocks, delivery times… If this data is unclear, the buyer abandons or calls your customer service. You lose the autonomy you wanted to create. Investing in a PIM (Product Information Management) like Akeneo to structure, enrich, and properly distribute your catalog. A good PIM allows you to centralize product data, organize it according to your sales channels, and offer a consistent experience, even with a large volume of references.

Our advice is to consider your entire ecosystem from the conception of your project. When we take over your Magento or Adobe Commerce project, we work directly with your ERP and/or PIM to structure all your data on a technical foundation that will guarantee your users a reliable and consistent experience.

Error n°3 : Ignoring the multichannel dimension of the decision-making process

Believing that a website will suffice to convince B2B decision-makers constitutes a dangerously reductive vision. The modern B2B buying process involves multiple touchpoints and information channels before the final decision.

Your prospects consult your website, but they also read comparisons on specialized sites, look for reviews on LinkedIn, participate in professional events, and solicit their professional network. Ignoring this multichannel dimension causes you to lose numerous influence opportunities.

Moreover, different stakeholders in the buying process use different channels. Technical decision-makers often favor specialized forums and online communities, while executives are more informed via LinkedIn and professional media.

It’s essential that you develop a consistent presence across all channels frequented by your prospects. Your message and positioning must be aligned, whether on your website, your LinkedIn profiles, your interventions at professional events, or your content published on sector platforms.

Creating content adapted to each channel used will allow you to maintain this global consistency. We also recommend implementing a cross-channel tracking system to understand how your prospects navigate between the different touchpoints you offer them. You can identify the most effective channels at each stage of the buying journey.

And within this multichannel vision, SEO also fits. Natural referencing is important, even crucial, for attracting quality and qualified traffic to your website. Ignoring this concept means your potential customers will have difficulty finding you online, which limits your sales opportunities.

Error n°4 : Neglecting prospect follow-up

In the B2B universe, sales cycles often extend over several months, even several years. Abandoning follow-up after a few weeks or months amounts to wasting all the efforts invested in lead generation. Data is a mine of valuable information that can help you understand your customers’ behavior and optimize your sales strategies. Not using data means you’re making decisions based on assumptions rather than facts.

This error is particularly costly because B2B prospects who aren’t ready to buy immediately are not lost prospects. They may simply be in a different phase of their reflection or facing temporary constraints (budget, priorities, organizational changes).

In this sense, without an appropriate nurturing system, your prospects forget your company and turn to more present competitors when they’re ready to buy. You then lose opportunities you had nevertheless identified and qualified.

The lack of follow-up also sends a negative signal about your professionalism and your ability to manage a long-term commercial relationship. If you can’t maintain contact during the prospecting phase, how can you ensure quality customer follow-up?

This is why you could, among other things, develop automated email sequences based on your prospects’ behavior and interests. These sequences must bring value to each interaction: practical advice, market analyses, invitations to exclusive events, relevant product news.

You can then segment your prospect base more finely to maximize personalization of your communications. A prospect who downloaded a cybersecurity white paper shouldn’t receive the same content as a prospect interested in business process optimization.

The scoring system is also very useful as it allows you to identify opportune moments to intensify commercial contact. When a prospect significantly increases their engagement level (repeated site visits, multiple downloads, webinar participation), your sales team should be alerted to propose human interaction. The objective is to remain present and useful, but without being perceived as insistent.

Error n°5 : Underestimating the importance of technical user experience

In B2B, your prospects are demanding professionals who use high-performance digital tools daily. They won’t accept a degraded user experience on your website or online commercial tools.

Technical problems (slow loading, bugs, unintuitive interfaces) are immediately perceived as negative signals about your ability to deliver quality solutions.

This is why your website must, among other things, be fast, secure, and perfectly functional on all devices. Professionals increasingly consult your content on mobile and tablet, particularly during travel or in meetings. A failing mobile version causes you to lose numerous opportunities.

You must model your buying journeys according to client typologies. Offer features like: online quote requests, validation workflows, group orders, term payments, multi-user management with differentiated rights…

Hyvä, for example, is an excellent front-end for Magento that allows offering a fast, mobile-friendly, and pleasant interface to navigate. The objective? Allow your clients to find what they’re looking for… even before having to ask the question.

In short, build a platform truly designed for professional use. And this is precisely one of the daily missions of our experts, who accompany our clients with whom you might share challenges.

Successfully implementing your B2B online sales strategy requires a methodical approach and particular attention to the specificities of this environment. Avoiding these five major mistakes gives you a solid foundation for developing an effective digital presence that generates business. The errors mentioned here are frequent, but they are not inevitable. Selling online in B2B is a demanding project, but extremely promising for companies that engage seriously.

The investment in these areas may seem significant, but the cost of inaction is much higher. And ultimately, the entire business is transformed: fewer frictions, more customer autonomy, more data, more recurrence… and above all, a clear competitive advantage in a world where digital agility is becoming a decisive criterion.
