The best B2B platform in 2025 - which solutions dominate?
Before we get into the details, it's worth taking a look at the market-valued solutions that are gaining the most popularity among B2B companies in 2025. Below is a brief overview of the four most frequently deployed platforms, along with the main advantages noted by users. The ranking is based on an analysis of the availability of features, the licensing model, technical support and customer feedback - both from small businesses and large corporations.
Magento Commerce B2B
It is a solution based on an open source engine, which is distinguished by high flexibility of product catalog configuration. Users value it for the extensive customization capabilities of its offerings. The cost of implementation is higher than for SaaS platforms, while the lack of transaction fees and self-managed hosting can result in a lower TCO in the long term.
Shopify Plus
This option operates on a SaaS platform model and attracts with its ease of use, built-in hosting and the ability to scale quickly as business grows. Limited B2B features (e.g., no advanced catalogs or individual price lists) are compensated for by an extensive app ecosystem from the App Store. It is worth paying close attention to the billing model, as this can generate large costs in the long run. Here there are different transaction fees depending on the plan and an annual license fee, as this can generate large costs in the long run.
OroCommerce
It is an open source platform dedicated to the B2B segment, offering, among other things, an advanced quoting module, multi-tenant mechanisms and extensive management of user rights and roles. The cost of implementation is the highest in the list, but advanced multi-tenant workflow features or integrations with ERP make it a popular choice for large distributors and manufacturers.
Sellina
It's a hybrid solution combining features of open source and SaaS, prepared for quick implementation of key B2B functions (individual price lists, quoting module, integrations with Comarch or Subiekt). It takes about 4 weeks to implement the basic version, and the implementation time for additional integrations is determined individually. A fixed, low license fee independent of turnover and an unlimited warranty minimize unforeseen expenses. You can read more about the combination of open source and SaaS at: What is "Open-SaaS?".
Each platform has its strengths - from the highly flexible Magento, to the easy-to-use Shopify Plus, to OroCommerce and Sellina, which combines the advantages of both worlds - both the speed of implementation and the ability to expand the system at will. The choice of the best solution depends on the size of the company, the scope of its product offerings and the resources to implement and maintain the system.
How do you choose the perfect B2B platform for your business?
Before deciding on a platform, it is worth answering three basic questions: How big is my company and what are its growth ambitions? What sales processes do I need to support from the first version of the system? What resources can I devote to implementation and subsequent maintenance and development? These answers will help narrow down the list of potential vendors.
The primary criterion is scalability - whether the chosen solution can handle both the current number of products and transactions and future growth of the catalog and site traffic. In the case of open source platforms, server infrastructure and caching mechanisms need to be planned additionally. In the SaaS model, much of the responsibility rests with the service provider, which can speed up implementation, but limits control over the environment.
The second key aspect is the ability to integrate with your company's central ERP systems. B2B e-commerce platforms should seamlessly exchange product, order and inventory data. In practice, this means ready-made connectors to popular solutions (e.g. Comarch, Subiekt) and, if necessary, flexible APIs. Also make sure the vendor provides support for configuration and integration testing to avoid costly fixes during implementation.
Another important category is security and compliance. Check whether the platform meets PCI DSS requirements for payment processing and whether it allows GDPR policies to be configured. Pay attention to the availability of backup mechanisms, disaster recovery and security audits. Best practices also apply to the protection of B2B customer data - including connection encryption and dashboard access control.
The final decision should take into account the licensing model and total cost of ownership (TCO). In an open source model, low licensing costs contrast with infrastructure and IT team expenses, while SaaS provides a predictable budget, but can generate transaction or overage user fees. Hybrid solutions, such as Sellina, often combine an inexpensive license fee with off-the-shelf infrastructure and support, making it easier to plan expenses.
Latest trends and innovations in the B2B platform market in 2025
The B2B platform market in 2025 is experiencing a true renaissance of innovations that are changing the way companies conduct wholesale and semi-wholesale trade. The first of the most important trends is the widespread deployment of AI-driven personalization solutions, allowing the creation of dynamic product recommendations in real time. By analyzing the behavior of business customers, it is possible to automatically generate customized offers, which increases conversion and improves the shopping experience.
Another innovation is the architecture headless commerce, which separates the presentation layer from the backend and enables independent work on the user interface. An example of the implementation of this innovation is Sellina as a system of B2B/B2C e-commerce. In practice, this allows for easy implementation of UI/UX changes, as well as the creation of multi-channel (omnichannel) experiences. Companies are increasingly using this architecture to respond almost in real time to market trends and customer needs.
A third pioneering trend is autonomous purchasing processes, where the platform enables business customers to create rules and workflows for order approval. This allows large enterprises to automate complex multi-level approval procedures, reducing order processing time and the risk of human error. The development of APIs and low-code configuration tools means that even companies with limited IT resources can quickly customize purchasing processes with their own rules.
What are the most common mistakes when implementing a B2B platform and how to avoid them?
Before you start implementing a platform, it's worth knowing the common pitfalls that can prolong a project or significantly increase costs.
The first and most serious mistake is the lack of precisely defined business requirements at the stage of the pre-implementation analysis. In practice, this leads to an excessive number of changes during development, often resulting in budget and schedule overruns. To prevent this, prepare a detailed functional and technical specification, taking into account the product catalog, pricing rules, workflow processes and integrations with ERP systems.
The second problem is sometimes underestimating maintenance and post-implementation support costs. When choosing an open source model, be aware of the need to hire or outsource an IT team to take care of hosting, updates, backups and security monitoring. With SaaS, these costs are often included in the subscription, but there may be additional charges for data transfer or exceeding user limits. Include these expenses in your long-term TCO calculation.
The third pitfall is skipping comprehensive performance and security testing before going into production. Without load-testing, you risk a drop in performance and conversion during peak traffic. Failing to conduct a security audit can expose you to customer data leakage incidents and violations of PCI DSS or GDPR standards. Plan your load-testing, penetration and functional testing schedule and prepare rollback procedures in case of failure.
How to choose and implement a B2B platform successfully in 2025?
Choosing the best B2B platform in 2025 is a multi-step process that requires analyzing business needs, comparing functionalities and accurately assessing implementation and maintenance costs. Start by defining criteria such as scalability, integrations with ERP, licensing model and technical support. Then compare the solutions available on the market - open source solutions, SaaS platforms and hybrid systems such as Sellina, which combines the best features of both models.
A key element is to test prototypes and conduct a pilot with selected users to validate the system architecture and business processes before a full launch. Don't forget to include in the budget the cost of maintenance, service support and possible functional changes in the future. It is worth supporting the implementation with a technology partner who has experience in B2B projects and understands the specifics of your sector.
