8 best practices for your enterprise-grade B2B commerce implementation

According to Gartner, 75% of B2B organizations will complete their highest revenue deals via digital channels. Even more striking:  

• 85% of B2B organizations now operate an eCommerce storefront or self-service portal, and over 50% are tapping into online marketplaces to reach customers. 

• 56% of B2B organizations drove new-product revenue growth through eCommerce in 2025. 

Given this landscape, B2B organizations relying on legacy platforms risk missing these opportunities. Taking advantage of modern commerce — especially as agentic AI rises — has become critical for manufacturers, wholesalers and distributors. Leveraging modern digital infrastructure helps them elevate buyer experiences, automate workflow and drive revenue growth.

To make the switch from monolithic to modern commerce faster, safer and more strategic, here are eight best practices to guide your journey.

The crucial mistake many B2B leaders make is assuming they know what buyers want and creating implementation plans without involving the people they need to impress. While it may seem obvious, uncovering customer expectations and the issues they face is critical. 

Here’s a great example: Mars (the company behind M&M’S, Skittles and Snickers) also offers products to businesses. Despite their sweet success, the B2B ordering process for the ice cream unit was far from palatable. After receiving frequent customer complaints, the Mars team decided to act. 

The first step? Talking to customers to create a prototype that they could test and give feedback on. In 90 days, the Mars team developed a prototype delivering what customers asked for. After implementing additional feedback, Mars created a frictionless order experience that wowed customers. 

In addition to customer feedback, identify internal business needs: 

• Reduce total costs of ownership (TCO). 

• Eliminate technical debt. 

• Enable hybrid sales teams. 

• Support omnichannel and personalization. 

Answering these questions ensures your platform selection aligns with both business and customer requirements.

Now that you know the business and customer needs, it’s time to think about your tech stack. If you’re on a legacy commerce platform and plan to migrate to a modular, composable architecture, you can do so in a phased approach (instead of the traditional “big bang” switchover). 

Migrating off a monolithic architecture to a modular one is ideal with a phased approach (AKA, the strangler pattern), which enables you to move one component at a time to the new infrastructure. This way, you can reduce the risk associated with the big-bang approach while reaping short-term benefits by shortening your migration’s time-to-value.

Which components do you need to elevate the buyer experience? The beauty of a modular platform is that it lets you break down your commerce infrastructure into components, so you can best evaluate what you need, what you can develop yourself and what to buy from best-of-breed vendors. This may include (but is not limited to) payment service providers (PSPs), inventory management, search and CMS systems. 

Next, assess the B2B eCommerce features that matter to you, such as personalized pricing, reordering and order scheduling, quote management. This ensures your commerce stack supports business objectives while avoiding unnecessary technical debt.

It’s worth noting that many B2B enterprises have invested time and money in homegrown commerce platforms in the hope of capturing their business-specific uniqueness in their tech stack. However, this approach usually falls short, as maintaining an internal DIY platform requires significant resources and, over time, tends to accumulate technical debt. 

A modular commerce platform provides the best combination of the build-and-buy approach: You can build what makes your business unique and buy the components that you don’t have the internal capability to create from scratch.

Start integrating the components you need. With a modular, API-first approach, you can integrate seamlessly, regardless of whether they’re built in-house, sourced from best-of-breed vendors or a mix of both. 

Most B2B enterprises should consider integrating ERP (Enterprise Resource Planning) systems with their commerce platform to maximize operational efficiency, automate processes, minimize expensive order errors and eliminate data discrepancies.

While some B2B organizations buy their ERP and commerce solutions from a single vendor for simplicity’s sake, this approach doesn’t necessarily yield the best results. This is because such solutions are tightly integrated (and therefore, monolithic in nature), which prevents the company from adapting customer experiences faster, customizing features and innovating at a fast pace. 

Decoupling commerce and ERP systems is not as complicated as you think. This is possible because, by definition, modular, API-first platforms enable seamless integrations without affecting the rest of your infrastructure.

Whether you call it a proof of concept (POC), a minimum viable product (MVP), a minimum testable product (MTP), a pilot project or a prototype, this is the stage in which you can test assumptions, collect data, refine your approach, mitigate risk by starting with a small-scale trial — and prove that a larger investment will pay off. 

This approach also helps validate assumptions before investing significant resources in a full-scale implementation, as well as identify potential problems or limitations early on, saving time and money in the long run. 

The pilot approach should test key hypotheses related to your business needs, such as: 

• Will implementing a new checkout process reduce cart abandonment by 15%? 

• Is it feasible to address tier 2 and tier 3 customers through digital channels?

• Can eCommerce generate revenue for low-complexity transactions, e.g., reordering? 

While you can select more than one hypothesis to test, don’t fall into the trap of overloading your pilot with multiple variables or objectives because it makes it harder to measure success. Instead, focus on a singular problem that directly impacts your business outcomes, such as improving revenue, reducing costs or enhancing operational efficiency. 

Finally, ensure your pilot adheres to the principles of incremental change and reversibility, so you can roll back the results if needed. By testing in a controlled environment, such as a subset of your customer base or a specific product line, you can assess the viability of your approach before making broader changes. This minimizes risk and allows you to adjust your strategy without causing disruptions. 

Finally, prioritize pilot programs that test new capabilities — like self-service portals, pricing automation or product availability tools — aligned with core business KPIs. Structure your roadmap to be 80% fixed, based on strategic priorities, and 20% agile, allowing flexibility to respond to urgent issues or new opportunities.

With the continuous growth and evolution of eCommerce, it’s paramount to ensure the security of online transactions and safeguard user data. That’s why B2B enterprises should prioritize security and compliance and watch out for: 

• A governance framework.

• Risk management. 

• Real-time monitoring.

• Data analysis.

• Complete isolation and segregation of persistent data. 

• Regular penetration tests.

• Compliance based on industry standards, which may include (but are not limited to) ISO/IEC 27001, TISAX, GDPR, etc. 

Using cloud-native commerce security further enhances protection. In contrast to on-premises IT, where you need to build and maintain all servers yourself, a cloud-native approach from Google Cloud and Amazon Web Services (AWS) provides the highest level of data separation. It also includes: 

• Automated security measures like backups and real-time threat detection. 

• Multi-layered security, including network firewalls, virtual private networks (VPNs) and encryption, to help ensure data protection at every level.

• Data recovery in the event of a disaster or system failure.

Test every component and integration in your composable stack to: 

• Identify compatibility issues across different tech stack components to avoid system crashes or data loss. 

• Ensure data integrity by verifying that data is accurately transferred between components of the tech stack, preventing data errors or corruption. 

• Optimize performance by identifying any bottlenecks to improve overall system performance and reduce downtime. 

For testing to become an integral part of your process, you can follow these four steps:

1. Develop a testing plan outlining what components will be tested, how testing will be performed and what metrics will be used to measure success. 

2. Use testing tools, such as load-testing software and performance-monitoring tools. 

3. Test constantly to ensure everything works without issues — or anticipate problems before they become a blocker. 

4. Record and analyze each test's results, identifying any areas of concern or opportunities for improvement. 

Here are a few ways B2B enterprises can monitor their digital commerce solution:

• Performance monitoring: Keep track of performance metrics such as page load time, server response time and transaction processing time to identify areas that could be optimized. Also, with real-time monitoring tools, you can identify issues as they occur, such as system crashes or slow page load times. 

• User monitoring: How does the B2B buyer behave? What areas of your platform is the user interacting with? By tracking the customer journey through the platform, analyzing user search queries and monitoring shopping cart behavior, you can spot expectations and issues that can be improved. 

• Analytics: Analyze data like customer behavior, product performance and sales data to identify trends and patterns that could be used to optimize performance.

More than monitoring and analytics, open and continuous communication with customers will help you stay on top of expectations and demands, so your innovations can cater to the people that matter the most — and your business is ready to capitalize on that.
