B2B Ecommerce Platforms: A Complete Guide for Merchandisers

Written by Noelina Rissman | Apr 1, 2025 2:30:00 PM

The B2B ecommerce market is projected to reach $36,107.63 billion by 2031, with businesses increasingly shifting to digital-influenced transactions. While more companies are investing in B2B ecommerce platforms, many struggle to provide the efficiency, flexibility, and searchability that business buyers expect.

B2B transactions involve multi-stakeholder approvals, contract-based pricing, bulk orders, and repeat purchases. Traditional ecommerce solutions aren’t always built for this level of complexity, making it harder for buyers to find what they need and for merchandisers to optimize for revenue.

This guide will show you how to choose the right B2B ecommerce platform, streamline operations, and improve buyer experience — while ensuring your ecommerce strategy is built for scale.

What is a B2B Ecommerce Platform? 

B2B ecommerce platforms are designed to streamline transactions between businesses. Buyers can make purchases with the same efficiency they expect in a B2C shopping experience, but with features tailored to the complex needs of business purchasing.

How B2B ecommerce has evolved

B2B ecommerce has gone through several major changes over the years:

  • EDI and Manual Processes: Early B2B transactions relied on Electronic Data Interchange (EDI), paper catalogs, phone orders, and email-based invoicing. These methods, while functional, lacked flexibility and required significant effort to manage.

  • Basic Online Marketplaces: The first generation of B2B marketplaces made it easier to list products and process transactions online, but these platforms were largely static, offering little in terms of personalization or efficiency.

  • Integrated, AI-Powered Platforms: Today’s B2B ecommerce solutions support real-time pricing, customized catalogs, AI-driven search, and seamless ERP/CRM integrations.

Types of B2B ecommerce models

Different businesses require different ecommerce models. The most common models include:

  • Marketplaces: Platforms that connect multiple buyers and sellers, acting as intermediaries (i.e., Amazon Business and Alibaba)

  • Distributors: Businesses that purchase products from manufacturers and resell them to other companies while managing inventory, fulfillment, and logistics

  • Manufacturers: Companies that sell directly to businesses rather than through intermediaries, often providing bulk discounts and custom pricing

  • Wholesalers: Businesses that buy large quantities of goods and sell them in bulk to retailers at lower per-unit costs

The shift to digital sales in B2B

B2B companies increasingly rely on digital sales channels to connect with buyers. 

Recent data shows that by the end of 2025, 80% of B2B sales will be conducted online. When buyers are already aware of a product or service, 64% prefer a totally online buying experience, which underscores the demand for seamless, self-service options. 

Companies that optimize their ecommerce experience see faster sales cycles and higher customer retention rates.

Why product discovery is critical in B2B ecommerce 

B2B catalogs contain thousands — sometimes millions — of SKUs. Without advanced search and filtering tools, finding the right product can be slow and frustrating, leading to abandoned carts and lost revenue.

AI-powered search and product discovery tools made for the complexities of B2B commerce ensure business buyers get accurate, relevant results instantly so they can keep operations running smoothly.

How Do B2B Ecommerce Platforms Differ from B2C?

B2B ecommerce operates on a different scale and level of complexity than B2C. 

While consumer-focused platforms prioritize one-time purchases and impulse-driven shopping, B2B platforms accommodate multiple decision-makers, long-term purchasing relationships, and highly structured pricing agreements.

Complex pricing structures and purchasing dynamics

B2B transactions involve far more variable pricing models than the fixed prices seen in B2C. Companies need flexibility to manage:

  • Bulk discounts for high-volume buyers
  • Tiered pricing based on order quantity or contract terms
  • Negotiated rates tailored to long-term partnerships
  • Customer-specific pricing based on pre-approved agreements

For example, an industrial supply company selling raw materials may offer one price for a small business ordering a few units, another for a regional distributor, and a custom-negotiated contract for a global enterprise. 

A strong B2B ecommerce platform supports these complex pricing arrangements, ensuring the correct pricing displays for each customer without manual updates.

Customer account structures

Unlike individual B2C customers, B2B buyers typically work within teams, requiring:

  • Multi-user accounts where different roles (e.g., purchasing manager, procurement specialist, finance team) have varying access levels
  • Approval workflows that allow orders to be submitted, reviewed, and approved before purchase
  • Repeat purchasing tools such as saved lists, pre-approved catalogs, and order history tracking

Personalization strategies also differ:

  • In B2C, personalization means recommending products based on browsing behavior or past purchases
  • In B2B, personalization is more about showing the right products and prices based on the buyer’s organization, industry, role, and negotiated agreements

Advanced order management capabilities 

B2B purchases are often large-scale, recurring, and require precise fulfillment coordination. A B2B ecommerce platform should include:

  • Quick reordering for repeat purchases with minimal clicks
  • Order approval workflows to maintain internal purchasing controls
  • Subscription and recurring order functionality for ongoing supply contracts
  • Quote management so customers can request pricing before finalizing an order
  • Location-based fulfillment so orders are routed to the correct warehouse or supplier based on geography and stock availability

Benefits of Implementing a Modern B2B Ecommerce Platform

Modern B2B ecommerce platforms can facilitate the seamless, digital-first purchasing experiences buyers have come to expect in addition to other key benefits:

  • Expanded market reach and new customer acquisition: Selling online eliminates regional limitations so businesses can scale without relying on in-person sales

  • Higher average order value (AOV): Personalized recommendations, volume discounts, and upsell strategies encourage buyers to purchase more per transaction. Canadian retail chain Princess Auto increased AOV by integrating AI-driven search and recommendations as part of its B2B tech stack, helping buyers discover complementary products

  • Lower cost of sales and customer service: Self-service portals and AI-powered search reduce the need for manual support, freeing sales teams to focus on high-value accounts

  • Faster sales cycles: Automated approval workflows, real-time pricing, and inventory visibility reduce friction in long B2B purchasing processes

  • Stronger buyer relationships and retention rates: Consistent contract-based pricing, customized catalogs, and AI-driven personalization improve buyer satisfaction. For instance, Fisheries Supply improved the customer experience and increased revenue from wholesale customers by implementing Constructor Search and Browse

  • Increased operational efficiency: AI-powered search and merchandising automation reduce manual work for merchandisers and procurement teams

  • Better data for decision-making: AI provides insights into buying patterns, search behavior, and conversion rates, allowing merchandisers to refine pricing and discount structures

Key Considerations and Features: How to Choose a B2B Ecommerce Platform

Evaluate your B2B platform options against the following features:

Strong partnerships with point search & product discovery solutions

B2B buyers often search using part numbers, SKUs, specifications, or compatibility filters, making it essential for B2B platforms to be integrated with solutions that can handle these search complexities. 

A strong search and product discovery solution should:

Advanced order management

B2B transactions involve larger orders, repeat purchases, and approval workflows. A well-equipped platform should:

  • Enable quick reordering for high-frequency buyers
  • Support bulk purchases with automated discounts based on contract terms
  • Provide order tracking, scheduling, and approval workflows to streamline procurement

Customer-specific catalogs and experiences 

Unlike B2C stores, where every visitor sees the same catalog, B2B platforms need to offer customized experiences. Look for:

  • Role-based access so buyers only see pre-approved products and pricing
  • Saved lists and favorite products, which help teams quickly reorder frequently purchased items
  • Catalogs personalized to specific buyers or contracts

AI-powered personalization helps repeat buyers find relevant products faster, reducing search time and increasing order value.

Integration capabilities 

A B2B ecommerce platform should connect seamlessly with essential business systems, including:

  • ERP (Enterprise Resource Planning) for real-time inventory updates
  • CRM (Customer Relationship Management) to track buyer interactions
  • Accounting and tax systems to automate financial processes
  • Inventory management tools for precise stock visibility
  • Product search and discovery to enhance catalog visibility 

A well-integrated platform ensures data consistency across all business systems, reducing errors and inefficiencies.

Payment flexibility 

B2B buyers require more than just credit card options. Platforms should support:

  • Account-based billing and pre-approved credit terms
  • Purchase orders (POs) and multi-currency transactions
  • Automated tax compliance to streamline invoicing across multiple regions

Security and compliance

B2B transactions involve sensitive pricing, contracts, and financial data. To maintain trust and long-term business relationships, a platform must:

  • Ensure data encryption and access controls to protect business-critical information
  • Comply with industry regulations (e.g., GDPR, PCI DSS) for secure payment processing
  • Provide user-based permissions to prevent unauthorized access

Other key considerations

Beyond what we’ve discussed, think about what your specific business may require from a B2B platform. Considerations might include:

  • Implementation timeline: How long will it take to get up and running? A platform that supports phased rollouts or quick integrations can minimize disruption
  • Mobile functionality: Can buyers and sales teams place and manage orders on the go? Mobile accessibility is increasingly important for B2B transactions
  • Ongoing support and maintenance: Does the provider offer reliable support when issues arise? A strong service team will help operations run smoothly after launch

Best B2B Ecommerce Platforms for Enterprise Businesses

While many ecommerce platforms offer B2B capabilities, a few stand out for their flexibility, scalability, and ability to handle advanced merchandising requirements.

1. commercetools

A leading API-first, headless commerce platform, commercetools is designed for enterprise businesses that need flexibility. Because it’s a modular system, companies can customize everything from pricing rules to product catalogs without being locked into a single structure.

2. Shopify Plus

Originally built for B2C brands, Shopify has expanded into B2B with Shopify Plus, offering dedicated tools for large-scale operations. The platform provides customized pricing, buyer-specific catalogs, and flexible payment options — all within an intuitive, self-service interface.

3. Magento (Adobe Commerce)

How Constructor Enhances B2B Ecommerce Platforms

B2B ecommerce platforms handle complex catalogs, contract-based pricing, and multi-step purchasing workflows. But without an intelligent search and discovery solution, even the most well-structured catalogs can become difficult to navigate.

Constructor takes an AI-first approach to product discovery so B2B buyers find exactly what they need — fast. By personalizing search, recommendations, and the entire product discovery experience in real-time, Constructor helps businesses improve KPIs like conversions, AOV, and buyer retention.

Key Capabilities:

  • AI-powered search that understands technical product data, part numbers, and compatibility relationships, surfacing the most relevant results for B2B buyers
  • Dynamic personalization that adapts product rankings, recommendations, and search results based on buyer behavior and account-specific preferences
  • Real-time optimization that continuously refines search relevance based on business objectives and merchandising priorities

Earlier, we mentioned Princess Auto, a leading B2B retailer. It was impossible for their team to optimize every important search query. So, they had to focus on select terms that could be tweaked manually. Many aspects of their on-site experience were being left behind.

After implementing Constructor’s AI-powered search and discovery solutions, Princess Auto increased:

  • Conversions by 22%
  • Revenue per visit by 247% 
  • Average order value by 14.5%

By optimizing search relevance in real time, Constructor enabled Princess Auto to deliver a frictionless B2B shopping experience.

Common Challenges When Implementing B2B Ecommerce Platforms and How to Address Them

Here’s how to tackle some of the most common B2B ecommerce platform obstacles:

  • Change management and internal adoption: Resistance to change is common, especially among sales teams used to traditional processes. Early involvement, clear training programs, and demonstrating platform benefits help drive internal adoption

  • Data quality and catalog management: Handling thousands (or even millions) of SKUs, varied pricing structures, and real-time updates is a major hurdle. AI-driven catalog management automates product categorization, reduces manual updates, and improves search relevance

  • Budget and ROI justification: Leadership often hesitates on making large investments without clear ROI. Businesses can prove value through pilot programs, A/B testing, and free trials before committing to full-scale implementation

  • Integration with legacy systems: Many businesses rely on ERP, CRM, and inventory management systems that weren’t built for modern ecommerce. Choose a composable, API-first platform for smoother integration without a complete system overhaul

  • Complex implementation processes: A drawn-out, resource-heavy implementation can stall progress. Work with a platform that provides hands-on support and structured onboarding to minimize internal burden and create a more seamless transition

Optimizing B2B Ecommerce for Growth and Efficiency 

B2B buyers expect seamless, efficient, and intelligent ecommerce experiences — but not all platforms are built to meet those expectations. The right solution should provide robust search and product discovery, personalized buyer experiences, seamless integrations, and efficient automation.

Assess your current platform against these criteria. Is it helping your business reach new customers, streamline operations, and drive revenue? Or is it slowing you down?

Constructor’s AI-powered solutions help B2B businesses optimize product discovery, enhance search relevance, and personalize the buying journey, so buyers find what they need quickly.

Frequently Asked Questions

  • How long does it typically take to implement a B2B ecommerce platform?

Timelines vary based on complexity, customization, and internal readiness. Some implementations take up to 18 months, while others can be completed in as little as six. Constructor’s search and discovery solutions integrate within 30-90 days, delivering immediate value even as broader platform changes are in progress. The best approach is phased implementation, ensuring steady progress rather than waiting for a single launch.

  • Can we maintain our sales team relationships while moving to a B2B ecommerce platform?

Absolutely. Digital transformation should enhance, not replace, personal relationships. Modern B2B platforms empower sales teams with shared carts, guided selling, co-browsing, and customer-specific notes, allowing them to collaborate digitally with clients. Many businesses also implement sales rep portals, where reps can track customer activity, place orders on behalf of clients, and receive account alerts. Involving sales teams early in the process ensures they see the value of automation, freeing them from administrative tasks so they can focus on high-value consultative selling.

  • How do B2B ecommerce platforms handle large catalogs with complex product configurations?

Managing extensive product catalogs requires robust PIM (Product Information Management) integration, faceted navigation, and AI-powered search to ensure accuracy and efficiency. Advanced ecommerce platforms are designed to maintain data quality across thousands or even millions of SKUs, preventing inconsistencies that could lead to purchasing errors.

These platforms also enable users to filter products based on technical specifications, making it easier to find the most relevant and attractive options, even in complex catalogues. Many solutions incorporate configuration engines that validate compatible product selections, ensuring buyers only see options that meet their specific requirements.

AI-driven search, like Constructor, takes this a step further by understanding technical terminology, product relationships, and buyer behavior. Whether a buyer is searching by part number, specifications, or compatibility needs, AI-powered search ensures they quickly find the right products, streamlining the decision-making process and improving overall efficiency.

  • Can B2B platforms support multiple languages, currencies, and tax regulations?

Leading ecommerce platforms go beyond basic translation, offering full internationalization capabilities to support global expansion. They include multi-language content repositories that account for cultural and industry-specific terminology, ensuring messaging resonates with local audiences.

Comprehensive pricing management allows businesses to operate in multiple currencies, with real-time exchange rate handling to maintain accuracy. Integrated tax compliance tools help companies comply with evolving regulations across different markets, reducing the risk of errors or non-compliance.

Additionally, these platforms support localized payment methods, shipping rules, and user experiences, providing a seamless purchasing process for international buyers. Choosing a platform with internationalization as a core feature streamlines content management while allowing for necessary regional adjustments, ultimately improving global reach and operational efficiency.

  • How do we migrate existing customer data and order history to a new B2B ecommerce platform?

Data migration can be complex, particularly for businesses with long-standing customer relationships and large order histories. A successful transition starts with assessing existing data to determine what is essential, what needs cleaning, and what can be archived. This ensures that only high-quality, relevant information is transferred to the new system.

Aligning data structures with the new platform’s requirements is also critical. Mapping fields and formats in advance prevents compatibility issues and streamlines integration. Taking a phased approach further reduces risk, prioritizing the migration of active customers, product data, and open orders before incorporating historical records.

Throughout the process, validating data accuracy is key to ensuring seamless functionality once the migration is complete. Rather than simply transferring legacy issues, businesses should treat migration as an opportunity to improve data quality. Many organizations choose to work with specialists to minimize disruptions and accelerate the process. Constructor integrates seamlessly with both historical and live data, preserving search relevance and personalization throughout the transition.

  • How can we prepare for the future of B2B ecommerce?

Staying competitive requires continuous evolution. Businesses should prioritize AI-driven personalization to enhance search, merchandising, and customer experiences, so buyers can quickly find relevant products. Omnichannel commerce is also essential for meeting shifting buyer expectations, providing a seamless experience across digital and physical touchpoints.

Scalability plays a key role in long-term success. So, it’s important to choose a flexible platform that adapts to international expansion, emerging trends, and evolving business needs. Future-proofing an ecommerce operation means committing to continuous optimization, allowing the platform to grow alongside the business rather than becoming a limitation.
