Platform Profiles: In-Depth Reviews
Adobe Commerce (Magento): Enterprise-Grade Customization and Complex B2B Workflows
Adobe Commerce offers one of the most comprehensive feature sets for businesses that require deep customization and full control over their commerce stack. The platform’s native B2B module covers customer-specific catalogs, negotiated pricing, quote management, requisition lists, and multi-tier approval workflows. As a certified Adobe Gold Solution Partner, Atwix has implemented dozens of enterprise B2B solutions on the platform across manufacturing, distribution, and wholesale.
Adobe Commerce’s open-source-based architecture provides significant flexibility for custom integrations. Cloud (PaaS) deployments retain full code-level customization: merchants develop and deploy custom modules, extensions, and integrations using Adobe’s Git-based deployment model, while Adobe manages the underlying cloud infrastructure. Adobe Commerce as a Cloud Service (ACCS), Adobe’s newer SaaS offering, follows a different model; the core application is Adobe-managed, and custom functionality runs through APIs, App Builder, and UI SDKs rather than direct code deployment into the Commerce core. Adobe Commerce offers no native connectors to ERP systems.
The trade-off is cost and complexity. Adobe Commerce on Cloud (PaaS) starts at approximately $80K/year for mid-market GMV tiers and scales to $190K+/year at enterprise GMV levels. Adobe Commerce as a Cloud Service (SaaS) is proceed separately; contact Adobe for a quote. For enterprise implementations, all-in platform costs including licensing, hosting, and support typically run $18K–$30K per month. Implementation for mid-sized projects typically takes 3–6 months with an experienced development team.
Pricing: $80K–$190K+/year (licensing, varies by deployment type and GMV); $100K–$500K+ (implementation); 15–20% of implementation cost annually for maintenance.
Best For: Enterprise manufacturers and distributors with complex product catalogs, multi-region requirements, and established IT teams.
Shopify Plus: Unified B2B and B2C Operations with Rapid Deployment
Shopify Plus is the leading choice for enterprise organizations running B2B and direct-to-consumer commerce from a single platform, with shared inventory, products, and customer data. As of April 2, 2026, Shopify extended foundational B2B features to all paid plans. Enterprise operations at scale require Shopify Plus for its exclusive capabilities: unlimited pricing catalogs with direct company and location assignment, partial payments and deposits, sales rep permission scoping, and checkout customization via Shopify Functions.
Native B2B features include customer-specific catalogs, tiered volume pricing, negotiated payment terms, and bulk ordering. Buyers access dedicated company accounts that display only their approved products at contracted prices. The checkout adapts automatically, presenting net payment terms for approved accounts without custom development.
Shopify’s integration ecosystem connects with Oracle NetSuite, SAP Business One and S/4HANA, Microsoft Dynamics, and Acumatica. During Black Friday/Cyber Monday 2024, the platform handled 284 million requests per minute across its global infrastructure, confirming enterprise-grade reliability. Shopify-published research shows unified commerce platforms deliver up to 22% lower total cost of ownership than multi-vendor stacks, with Shopify’s platform TCO running up to 68% lower than major competitors’ over three years.
Pricing starts at $2,300/month on a three-year term. At high GMV volumes, billing shifts to a variable fee reaching up to $40,000/month. A transaction fee on third-party payment gateways (approximately 0.20%; rate is negotiated at enterprise volume) and app costs ($500–$3,000/month) require modeling in total cost projections.
Pricing: $2,300–$2,500/month (license, 3-year term); scales to variable fee at high GMV; $30K–$150K+ (implementation).
Best For: Brands operating B2B and B2C channels simultaneously; organizations with rapid deployment requirements; companies prioritizing lower three-year TCO.
Shopware: Global B2B Commerce with GDPR-Native Architecture
Shopware is a leading platform in the European B2B eCommerce landscape, built with native GDPR compliance, multi-language support, and EU regulatory requirements. As a Shopware Platinum partner, Atwix delivers enterprise implementations across Europe and North America.
Shopware’s B2B Components suite (available from the Evolve tier) provides tiered individual pricing, advanced product management, and multi-company account structures via Organization Units. Full customer-specific price lists per customer are a Beyond-tier feature. The platform’s component-based architecture allows organizations to activate only the features they need, keeping systems lean while preserving scalability. Shopware handles complex VAT scenarios, country-specific payment methods, and regional compliance requirements that frequently challenge US-built alternatives.
Shopware 6’s technology stack is built on Symfony PHP, with a default storefront using Twig templates, SASS, Bootstrap 5, and vanilla ES6. Every feature is accessible via REST/JSON API, and the platform
Pricing: $700–$7,500/month (published tiers: Rise, Evolve, Beyond; pricing is published in EUR and converted at ~$1.15/€); enterprise all-in costs including hosting and support typically run $8K–$15K/month; $50K–$200K+ (implementation).
Best For: Mid-market to enterprise B2B organizations prioritizing composable, API-first architecture; businesses requiring strong native B2B features with a lower entry cost than Adobe Commerce; and organizations with multi-language, multi-currency, or global compliance needs.
BigCommerce: Headless Architecture for Multi-Storefront Operations
BigCommerce targets enterprises adopting headless and composable commerce. Its API-first foundation provides robust backend functionality while giving frontend teams full freedom in customer experience design. The B2B Edition includes custom pricing, quote management, and company account structures supported by mature REST and GraphQL APIs.
For businesses requiring multiple storefronts across regions or brands, BigCommerce supports multi-store deployments managed from a single admin. The standard Performance plan supports up to five storefronts; higher counts are negotiable on custom enterprise contracts. Each storefront maintains distinct product catalogs, pricing rules, and regional settings while sharing underlying infrastructure. The SaaS model includes automatic platform updates, PCI compliance, and 99.99% uptime without requiring dedicated DevOps resources.
As of June 2026, BigCommerce charges an Open Payment Provider Fee on third-party payment gateways, ranging from 0.6% to 2% depending on plan. Performance plan (enterprise) pricing starts at approximately $1,750/month (custom quote) and scales with GMV and feature requirements; implementation ranges from $40K–$180K+.
Pricing: Custom (~$1,750–$8,000+/month, scales with GMV); $40K–$180K+ (implementation); 0.6%–2% Open Payment Provider Fee on third-party gateways, varying by plan (from June 2026).
Best For: Brands building headless commerce architectures, managing multi-region storefronts, and organizations with strong internal development teams building custom frontends.
Real-World Results: Case Study Insights
PowerPak: 230% Growth Through Platform Optimization
PowerPak, a leading supplier of safety equipment to construction sites, faced a specific problem: their aging Magento platform could not support same-day delivery requirements. When supplies run out on a construction site, work stops. A slow or unreliable ordering portal was a direct operational liability.
Atwix performed an audit, migration, and redesign: upgrading PowerPak’s existing Adobe Commerce platform from an outdated Magento version, implementing advanced product filters and quick-order functionality, and improving site performance through storefront, catalog, and navigation improvements. Total timeline: three months. Following launch, Atwix continued working with PowerPak on warehouse system integrations and ongoing UX improvements.
Results: 230% eCommerce growth (measured over 12 months following launch), 89% customer retention, 6% cost-per-order reduction.
Key Takeaway: The key is diagnosing the actual problem. In PowerPak’s case, the underlying issue was operational gaps in the existing implementation. Platform optimization often delivers stronger ROI than a complete rebuild when the core architecture remains sound.
Byrne Electrical: Eight-Week B2B Portal Launch
Byrne Electrical needed to modernize B2B selling: complex product customization, part number lookup, customer shipping account integration, and ERP integration, all within a tight eight-week timeline. Manual processes were limiting both the customer experience and sales team capacity.
Atwix implemented Adobe Commerce using a phased approach the team called the “lowercase MVP,” prioritizing the most critical features for launch: ERP integration, 360-degree product views, non-catalog product functionality, and customer shipping account integration. Timeline: eight weeks to go live.
George Fabis, Director of IT at Byrne Electrical, explained: “We wanted to empower our B2B customers by making the order process simpler. We also wanted to empower our extremely knowledgeable salespeople and help them be order makers, not just order takers.”
Results: Complete B2B portal replacing manual processes, 35% improvement in order accuracy, simplified customer ordering, and a sales team repositioned from order entry to strategic selling.
Key Takeaway: Phased deployment prioritizing core functionality accelerates time to value. Launching with core features and iterating post-go-live reduces risk and speeds ROI more reliably than attempting feature completeness before launch.
Industry-Specific Recommendations
Manufacturing: Complex Products and Deep ERP Integration
Primary Challenges: Products with thousands of configurable options, real-time inventory across multiple facilities, complex pricing matrices, and deep ERP or MRP integration.
Recommendations: Adobe Commerce leads for manufacturers with complex catalogs and established IT teams. Custom development becomes necessary when product configuration requirements exceed platform capabilities, or when competitive advantage depends on proprietary configurators. Hybrid implementations work well: deploy Adobe Commerce for core functionality while custom-developing specific modules such as CAD integration or multi-variable product configurators.
Distribution: Inventory Complexity and Customer Segmentation
Primary Challenges: Multi-location inventory, deep customer hierarchies, customer-specific pricing, multiple fulfillment options, and high-volume repeat ordering.
Recommendations: Shopify Plus works well for distributors with straightforward catalogs and standard customer hierarchies. Adobe Commerce better serves operations with extreme inventory complexity. BigCommerce offers a strong headless option for distributors managing multiple storefronts or brands. For a detailed example of distribution-specific requirements, see the PowerPak case study above.
Wholesale: Volume Transactions and Relationship Management
Primary Challenges: High-volume transactions with approval chains, customer-specific catalogs, negotiated pricing, split billing, and sales rep management.
Recommendations: Adobe Commerce excels with sophisticated account management and quote workflows. Shopify Plus serves wholesalers transitioning from spreadsheets and manual ordering to digital self-service. Custom development warrants consideration for deeply embedded sales processes or proprietary approval logic that no platform can replicate natively.
Integration Capabilities: The Critical Connection
For B2B organizations, integration capabilities often determine platform success more than feature sets.
ERP Integration
ERP integration synchronizes products, inventory, pricing, customers, and orders across your full system. A robust marketplace of prebuilt third-party connectors covers SAP, Oracle NetSuite, and Microsoft Dynamics for Adobe Commerce, alongside robust APIs for legacy systems. Shopify Plus offers certified native connectors for NetSuite, Microsoft Dynamics 365 Business Central, and Acumatica through its Global ERP Program; middleware platforms such as Celigo or Jitterbit are typically used for complex or legacy ERP scenarios outside that program.
| ERP System | Adobe Commerce | Shopify Plus | Shopware | BigCommerce |
|---|---|---|---|---|
| SAP S/4HANA | Third-party prebuilt connector | Native app (S/4HANA Cloud) / Middleware (on-premise) | Prebuilt EU connector (Alumio) | API + middleware |
| Oracle NetSuite | Third-party prebuilt connector | Native apps available | API integration | Native apps available |
| Microsoft Dynamics | Third-party prebuilt connector | Native apps available | Prebuilt EU connector (Alumio) | API + middleware |
| Epicor | Custom dev / MuleSoft | API / limited third-party | API integration | API integration |
| Legacy / Custom ERP | API + custom dev | Middleware required | API + custom dev | API + custom dev |
CRM and WMS Integration
For CRM, Adobe Commerce connects to Salesforce through marketplace extensions and API; Shopify Plus connects through App Store apps and API. Neither platform ships with a built-in Salesforce connection. Shopware and BigCommerce also connect to Salesforce through API integration. All four platforms support HubSpot, with Shopify Plus and BigCommerce offering native app connections. For WMS, enterprise systems such as Manhattan Associates and Blue Yonder require middleware or custom API integration across Adobe Commerce, Shopify Plus, and BigCommerce alike. Real-time inventory sync is supported across all four platforms, through native functionality on Adobe Commerce and through app or API connections on the others.

Three-Year Total Cost of Ownership
For a mid-market B2B company generating $20 million in annual online revenue:
- Adobe Commerce: $150,000–$400,000+
- Shopify Plus: $82,000–$180,000
- Shopware: $120,000–$300,000
- BigCommerce: $110,000–$250,000
- Custom Solution: $480,000–$1,400,000*
*Custom Solution three-year total reflects year-one build costs plus year-two and year-three ongoing expenses: hosting ($15K–$40K/year), maintenance ($40K–$100K/year), and updates and feature development ($25K–$75K/year). Lower-end implementations reduce total proportionally.
Hidden Costs to Model Before Committing
Transaction Fees: Shopify Plus charges approximately 0.20% on third-party payment gateways; at $10M annual revenue, that totals approximately $20,000 per year. As of June 2026, BigCommerce also charges an Open Payment Provider Fee on third-party payment gateways, ranging from 0.6% to 2% depending on plan (Performance/enterprise rates are negotiated).
Upgrade Cycles: Adobe Commerce and Shopware require periodic upgrades costing $20,000–$75,000 every 18–24 months.
Middleware: Shopify Plus and BigCommerce frequently require integration middleware at $1,500–$5,000 per month for complex ERP scenarios.
Retained Development: Budget $5,000–$15,000 per month for agency or contractor support across all platforms when your organization lacks in-house eCommerce developers.
Choosing the Right Approach: Platform, Hybrid, or Custom
Most successful B2B eCommerce implementations blend a proven platform with targeted customization on specific differentiators. The decision matrix below helps identify the right starting point.
When Platforms Are Sufficient
Pre-built platforms work exceptionally well under these conditions:
- Standard B2B Workflows: If your sales process follows common patterns, including customer accounts, pricing tiers, approval workflows, and quote requests, a platform delivers these without custom development. PowerPak’s same-day delivery challenge (see case studies above) illustrates this pattern: straightforward operational gaps were resolved through platform configuration in three months.
- Limited IT Resources: Organizations without dedicated development teams benefit from managed infrastructure, automatic updates, and large support ecosystems.
- Predictable Scalability: If your growth follows standard patterns, platforms scale effectively within their architectural constraints.
When Custom Development Warrants Consideration
Custom development makes sense when requirements fundamentally diverge from what any platform delivers: proprietary pricing or configuration logic that cannot be replicated in a pre-built system, or a direct competitive advantage that depends on proprietary technology. For most organizations in manufacturing, distribution, and wholesale, a hybrid approach, deploying a proven platform for core functionality while custom-developing specific differentiating modules, delivers the better balance of speed, cost, and flexibility.

Frequently Asked Questions
Which B2B eCommerce platform is best for manufacturing companies?
Adobe Commerce is one of the most established platforms for complex manufacturing requirements, particularly for businesses with highly configurable product catalogs and deep ERP or MRP integration needs. For manufacturers that also sell direct-to-consumer alongside B2B, Shopify Plus provides a unified platform approach. Custom development is warranted when product configurators require proprietary logic beyond what any pre-built platform can deliver.
How do Adobe Commerce and Shopify Plus compare for B2B?
Adobe Commerce offers greater depth for complex B2B workflows: approval hierarchies, native quote management, and established ERP connectors. Shopify Plus prioritizes speed to market and unified B2B/B2C operations at a lower three-year TCO. Organizations with standard B2B workflows, faster deployment requirements, or limited in-house technical resources typically find Shopify Plus a stronger fit. Adobe Commerce is the better choice when catalog complexity, customization depth, or legacy ERP integration requirements exceed Shopify’s native capabilities.
What is the total cost of implementing a B2B eCommerce platform?
Three-year TCO ranges from $82,000 (Shopify Plus, lower-volume implementations) to $570,000+ (Adobe Commerce, enterprise scale). The complete picture includes licensing, implementation, ERP integration, customization, training, ongoing maintenance, and hidden costs such as transaction fees, upgrade cycles, and middleware.
What is the difference between a B2B eCommerce platform and a custom-built solution?
Platforms (Adobe Commerce, Shopify Plus, Shopware, BigCommerce) are pre-built software products with native B2B features. Custom development builds a commerce system from the ground up for your specific business logic. Platforms offer faster deployment (2–9 months), lower upfront cost, and continuous vendor-funded feature development. Custom development provides unlimited flexibility and competitive differentiation, at 3–6x the total cost of a comparable platform deployment and 2–3x the deployment timeline.
Which B2B eCommerce platforms integrate with SAP?
Adobe Commerce provides access to third-party prebuilt connectors for SAP S/4HANA through its marketplace and is a strong option for SAP-standardized organizations. Shopware includes prebuilt EU-oriented SAP integrations. Shopify Plus offers a native app for SAP S/4HANA Cloud; on-premise SAP deployments typically require middleware such as Celigo or Jitterbit. BigCommerce requires middleware for SAP integration, adding $1,500–$5,000/month in middleware costs.
Which B2B eCommerce Platform Fits Your Organization?
Adobe Commerce, Shopify Plus, Shopware, and BigCommerce each serve distinct organizational profiles. Matching the platform to your integration complexity, deployment timeline, three-year TCO, and technical capacity determines whether eCommerce drives revenue growth or creates ongoing operational drag.
The case studies in this analysis demonstrate what the right match delivers: 230% eCommerce growth for PowerPak and an eight-week B2B portal launch for Byrne Electrical.
