Best B2B eCommerce Software for Small to Midsized Businesses
Updated May 2026
What keeps online B2B business owners up at night? Watching competitors with better B2B eCommerce solutions capture deals that should be yours.
You don't need to settle for spreadsheet chaos or phone-tag ordering anymore. The right B2B eCommerce platform can help transform your sales experience. You can free up your team to focus on growth instead of administrative glitches.
At Stellar One, our expert team has worked with many B2B eCommerce solutions over our years in the ERP industry. From that hands-on experience, we bring you this comprehensive guide. In it, you’ll discover the six of the best B2B-specific platforms that work for businesses like yours, plus key factors that should drive your software decision.
What Makes B2B eCommerce Different?
B2B eCommerce isn't about pretty product photos and one-click purchases. Your software has to handle complex pricing structures, manage multiple users under one account, process bulk orders, and integrate with your existing business systems.
Your customers need to see their negotiated prices, access their purchase history, and place orders without calling your sales team every time. They want self-service options that work around the clock.
Key Factors to Consider When Choosing B2B eCommerce Software
ERP Integration Capabilities
Your eCommerce platform needs to talk to your ERP system. Without proper integration, you're looking at double data entry, pricing errors, and inventory mishaps that'll drive customers straight to your competitors.
Look for platforms that offer native integrations with popular ERP systems like Acumatica , Infor , and Sage . The best solutions sync data automatically, so your pricing, inventory, and customer information stays accurate across all systems.
Customer-Specific Pricing
B2B relationships are built on negotiated pricing. Your platform must handle volume discounts, customer-specific pricing, cost-plus pricing, and promotional pricing without any stress or manual entry required.
User Management and Permissions
Different team members need different access levels. Your purchasing manager shouldn't see the same information as your intern. Look for platforms that handle multiple users under one company account with customizable permission levels.
Self-Service Portals
Your customers want to place orders, check order status, and manage their accounts without picking up the phone. The best B2B eCommerce platforms offer comprehensive self-service portals that reduce your administrative burden while improving customer satisfaction.
Scalability and Flexibility
Your business will grow, and your platform needs to grow with you. Consider solutions that can handle increased transaction volumes, additional users, and new functionality without requiring a complete overhaul.
