It covers Publicis Sapient, Accenture, Deloitte, IBM Consulting, Capgemini, EPAM Systems, Globant, TCS Interactive, Valtech, and Slalom with provider-specific capabilities and delivery patterns. The guidance focuses on selection criteria that match real B2B commerce operating-model complexity.

B2B E-Commerce Services deliver storefront and portal capabilities for business buyer journeys tied to real ordering workflows like CPQ, order orchestration, and ERP-backed fulfillment. The services solve problems such as fragmented product and pricing experiences, slow or incorrect order placement, and brittle integrations between commerce, OMS, and enterprise systems. Providers like Publicis Sapient implement end-to-end B2B commerce transformations across storefront, order management, and enterprise systems. Providers like Accenture connect CPQ, ERP, and order orchestration into unified storefront and back-office flows for large enterprise environments.
Key Capabilities to Look For
B2B commerce success depends on capabilities that connect customer experience with accurate ordering and operational systems.
End-to-end B2B transformation across storefront, OMS, and enterprise systems
Publicis Sapient excels at end-to-end B2B commerce transformation spanning storefront engineering, OMS, and enterprise systems. Deloitte and Valtech also focus on enterprise commerce transformation that orchestrates OMS and ERP-connected operating flows.
ERP, CRM, and order orchestration integration
Accenture specializes in integrating ERP, CRM, and order management workflows into a unified storefront and back office flow. Deloitte, IBM Consulting, and Slalom also emphasize systems integration that ties storefront actions to back-office orchestration for accurate pricing and ordering.
CPQ, complex pricing, and approval workflow orchestration
Accenture is positioned for CPQ and order orchestration integration with enterprise systems that drive pricing and ordering correctness. Capgemini and Valtech stand out for orchestrating B2B order, pricing, and approvals across ERP and commerce front ends.
Composable and headless storefront engineering with omnichannel delivery
Publicis Sapient delivers headless and omnichannel storefront engineering that supports modern B2B digital journeys. EPAM Systems also provides storefront and platform modernization with headless delivery patterns for enterprise-scale B2B deployments.
Catalog, master data, and PIM-to-order workflow integration
EPAM Systems targets integration across ERP, OMS, PIM, and fulfillment services to reduce data and process fragmentation. IBM Consulting and Deloitte similarly emphasize master data, catalog, and integration rigor when landscapes span ERP, OMS, and identity systems.
Enterprise governance, testing, and release quality controls
EPAM Systems provides structured delivery with testing and release governance for performance, security, and release quality. IBM Consulting and Deloitte also emphasize mature governance and compliance rigor for complex B2B commerce changes.
How to Choose the Right B2B E-Commerce Services
Selection should match program scope, integration depth, and internal product ownership capacity to the provider’s delivery model.
Match provider delivery scope to integration depth
If the program requires coordinated change across storefront, OMS, and ERP, prioritize Publicis Sapient for end-to-end B2B commerce transformation and measurable digital journey performance. For programs centered on CPQ and order orchestration, choose Accenture to integrate CPQ and enterprise systems into unified storefront and back-office flow. For governance-heavy enterprise modernization that requires careful orchestration across OMS and ERP, select Deloitte or IBM Consulting for transformation delivery with deep systems integration.
Verify OMS and ERP orchestration capabilities for ordering correctness
For accurate B2B ordering and order orchestration, use Deloitte, Slalom, or Valtech where enterprise integration work links storefront actions to OMS and ERP workflows. Capgemini is a strong fit when pricing and approval logic must be orchestrated across ERP and commerce front ends. For supply chain-connected landscapes, IBM Consulting provides integration across ERP, OMS, and supply chain systems.
Evaluate commerce UX strength against your buyer roles and journeys
When user experience and measurable conversion or retention outcomes are central, Publicis Sapient ties experience design to performance improvement across digital journeys. Globant focuses on conversion and fulfillment accuracy improvements tied to complex catalogs and buyer hierarchies. If rapid storefront iteration speed is critical, balance the need for governance with the provider’s ability to execute UX changes without excessive handoffs, since several enterprise-focused providers can slow iteration under governance.
Assess data and catalog readiness with PIM and master data integration
If product information and master data integration is required, prioritize EPAM Systems because it connects ERP, OMS, PIM, and fulfillment to reduce data fragmentation. For multi-entity landscapes and standardized B2B processes like pricing and approvals, Capgemini’s governance and process alignment support is a fit. For identity, catalog, and integration across enterprise systems, IBM Consulting emphasizes integration skills for master data, catalog, and identity.
Plan internal product ownership and governance bandwidth early
For complex commerce programs, Publicis Sapient, Deloitte, and IBM Consulting perform best when governance is matched to internal product ownership because delivery complexity can increase without clear ownership. When scope drift risks exist across multiple systems, Slalom emphasizes disciplined program execution, and TCS Interactive supports integration-heavy storefront and back-office requirements. If documentation and stakeholder alignment cycles are likely to slow early iteration, Globant and TCS Interactive require structured alignment to keep requirements mapped to multi-system workflows.
Who Needs B2B E-Commerce Services?
These services fit organizations that need B2B ordering and operational workflows embedded into digital self-service experiences.
Enterprise B2B programs needing integrated storefront, OMS, and ERP transformation
Publicis Sapient is best aligned because it delivers end-to-end B2B commerce transformation across storefront, order management, and enterprise systems. Deloitte, Valtech, and EPAM Systems also target OMS and ERP-connected transformation work with governance and system integration depth.

Slalom also works well for integration-heavy commerce programs connecting storefront, ERP, and OMS for order orchestration and adoption support.
Common Mistakes to Avoid
Buyer missteps usually come from underestimating integration complexity, governance demands, or the need for process and data readiness.
Treating B2B commerce as a storefront-only project
Programs that focus only on front-end UI often fail when OMS and ERP ordering workflows are not designed together, which is why Publicis Sapient and Deloitte emphasize end-to-end transformation across storefront and enterprise systems. Valtech and Slalom also position storefront work around accurate integration for order orchestration.
Under-allocating governance and product ownership for multi-system delivery
Several enterprise-focused providers like IBM Consulting and Capgemini require strong client-side product ownership to keep requirements aligned and prevent roadmap sprawl. EPAM Systems and Deloitte also use structured governance and can slow iteration when stakeholder coordination is insufficient.
Skipping master data and PIM integration planning
Data fragmentation breaks pricing and product presentation, and EPAM Systems explicitly targets ERP, OMS, PIM, and fulfillment integration to reduce fragmentation. IBM Consulting and Deloitte also emphasize master data and catalog integration across enterprise landscapes that include identity and ERP workflows.
Choosing a provider without a fit for complex pricing approvals and buyer permissions
Capgemini and Accenture are strong choices when pricing logic includes approvals or CPQ-driven ordering steps that must map to ERP orchestration. Globant also focuses on buyer hierarchies and permissions that influence conversion and fulfillment accuracy for complex catalogs.
How We Selected and Ranked These Providers
