It covers Accenture, Capgemini, IBM Consulting, PwC, KPMG, EPAM Systems, Tata Consultancy Services, Infosys, Globant, and Publicis Sapient. The guide maps concrete capabilities and common delivery pitfalls directly to what these providers do best.
What Is B2B Ecommerce Services?
B2B Ecommerce Services are consulting and engineering engagements that build or modernize B2B storefronts and digital buying journeys while integrating them with ERP, OMS, CRM, catalogs, and pricing systems. These services solve order-to-cash bottlenecks by connecting account-specific rules, catalogs, approvals, and order processing to back-office systems. For example, Accenture focuses on B2B order orchestration and integration engineering across ERP, OMS, and catalog systems, while Globant emphasizes headless and composable commerce for large B2B storefront ecosystems. PwC and KPMG often pair technology delivery with operating model design and risk-aligned governance for multistakeholder transformations.
Key Capabilities to Look For
These capabilities determine whether a B2B ecommerce program ships usable storefront functionality or stalls on integration complexity, governance overhead, and data readiness.
B2B order orchestration and ERP-to-OMS integration
B2B ecommerce succeeds when order placement, status updates, and fulfillment events move cleanly between storefront and enterprise order management. Accenture is built around B2B order orchestration and integration engineering for ERP, OMS, and catalog systems, and Tata Consultancy Services is strong in order management modernization with ERP and OMS integration under enterprise governance.
Catalog, pricing, and tax workflow engineering
Catalog publishing, account-specific pricing, and downstream pricing impacts must be consistent from quote to order. Accenture and Capgemini deliver B2B catalogs and pricing and wire them to enterprise workflows, while Infosys focuses on complex pricing, promotions, and procurement workflow alignment.
B2B approvals and procurement-aligned buying flows
Many B2B organizations need approval steps that map to internal buying controls and procurement motions. Capgemini provides B2B-specific functionality for catalogs, approvals, and pricing, and PwC connects procurement and sales process design to ERP and OMS integration oversight.
Composable and headless commerce architecture for B2B storefronts
Composable and headless approaches help teams modernize large storefront ecosystems without rewriting every dependency at once. Globant is strong in headless and composable architecture delivery for large B2B storefront ecosystems, and EPAM Systems supports composable and headless buildouts for B2B catalogs and customer-specific pricing.
Customer identity and order journey integration with enterprise systems
A smooth B2B journey depends on identity, account context, and consistent order experiences across systems. IBM Consulting pairs integration-heavy execution for orders, catalogs, and customer identity with transformation programs, while Publicis Sapient ties commerce and customer journey orchestration to ERP and CRM systems.
Program governance, risk controls, and release coordination
Enterprise B2B programs often span multiple systems and markets, which requires governance to keep integrations, security, and delivery sequencing aligned. PwC and KPMG emphasize program governance and risk controls for multiyear ecommerce change, and Accenture adds program management rigor for large multi-region ecommerce rollouts.
How to Choose the Right B2B Ecommerce Services
A practical selection framework pairs the provider’s strongest delivery pattern to the integration complexity, governance needs, and storefront modernization scope of the B2B initiative.
Start with integration scope and pick providers proven in your back-office stack
Map each storefront capability to the enterprise systems that must respond, including ERP, OMS, catalogs, pricing engines, and master data. Accenture and Capgemini are strong choices when B2B integrations must cover catalogs, pricing, tax, and order workflows tied to complex wholesale processes, while EPAM Systems and IBM Consulting fit when integration execution must also include composable or cloud delivery patterns.
Validate B2B-specific functionality like approvals, account-based rules, and procurement flows
Confirm that catalog access, approval requirements, and purchasing controls are supported as functional requirements, not afterthoughts. Capgemini delivers B2B approvals and pricing workflows tied to enterprise systems, and PwC designs procurement and sales process flows that connect to ERP and OMS integration.
Choose an architecture approach that matches modernization risk
Select composable or headless architecture when large storefront ecosystems need staged modernization and integration isolation. Globant delivers headless and composable architecture for large B2B storefront ecosystems, and EPAM Systems supports composable and headless buildouts for B2B catalogs and customer-specific pricing.
Set governance expectations and match the engagement style to internal decision speed
Enterprise governance can reduce rework across complex transformations, but it can slow decision cycles for teams needing rapid iteration. PwC and KPMG provide robust program governance and risk management rigor for multistakeholder transformations, while Accenture and IBM Consulting emphasize governance at enterprise program scale that can feel heavy if internal processes are not ready.
Run a data readiness check before selecting the delivery partner
Order orchestration and pricing logic depend on data quality for catalogs, customer accounts, pricing rules, and integration mappings. Accenture and Capgemini place value realization risk on integration readiness and data quality, while Infosys and Tata Consultancy Services focus on aligning integration work with pricing, promotions, procurement workflows, and operational governance across complex programs.
Who Needs B2B Ecommerce Services?
B2B Ecommerce Services are most beneficial for organizations modernizing storefronts and order flows that must integrate with enterprise systems across catalogs, pricing, procurement, and order management.
Large enterprises modernizing B2B storefronts with complex back-end integrations
These teams need deep engineering that connects storefront journeys to ERP, OMS, and master data workflows. Accenture and Capgemini are direct fits when integrations span catalogs, pricing, tax, and order workflows, and EPAM Systems is a strong choice for large engineering delivery tied to enterprise integration patterns.
Enterprises requiring B2B order and pricing complexity with governance-heavy transformations
These organizations need order orchestration, customer identity alignment, and risk-managed program governance across multiple stakeholders. IBM Consulting pairs integration-heavy execution with data and AI services for customer and demand analytics, while PwC and KPMG provide transformation governance that aligns commerce with ERP order flows and operating model improvements.
Organizations that need headless or composable storefront modernization for B2B ecosystems
Headless and composable approaches are a better match when large storefront ecosystems require staged modernization and flexible integration boundaries. Globant specializes in headless and composable architecture delivery for large B2B storefront ecosystems, and EPAM Systems supports composable and headless buildouts with enterprise integration across ERP, CRM, and order management.
Enterprises modernizing procurement-aligned buying journeys and approval workflows
These teams need B2B-specific buying controls and procurement flow design that translate into working system integrations. Capgemini provides B2B approvals and pricing workflows tied to enterprise systems, while PwC focuses on procurement and sales process design connected to ERP and OMS integration oversight.
Common Mistakes to Avoid
Common failure patterns across these providers come from mismatch between integration complexity and engagement style, plus data readiness gaps that directly impact pricing, catalogs, and order processing.
Underestimating integration readiness and data quality for pricing and ordering
Accenture flags that value realization depends on integration readiness and data quality, which means low-quality catalogs or pricing rules delay order orchestration. Capgemini also highlights that commerce modernization requires internal alignment on data and workflows, so inaccurate master data and unclear pricing inputs can slow delivery across ERP and OMS.
Choosing a governance-heavy engagement when internal decision speed is low
PwC and KPMG emphasize program governance and stakeholder risk controls, which can slow iterations for teams needing fast, lightweight change. IBM Consulting and Accenture also bring heavy governance at program scale, so organizations with limited stakeholder alignment readiness often experience slower delivery cycles.
Treating B2B approvals and procurement controls as UX-only work
Capgemini covers B2B approvals and pricing workflows tied to enterprise systems, which shows these requirements cannot be limited to front-end screens. PwC ties procurement and sales process design to ERP and order management integration oversight, which prevents approvals from breaking during order-to-cash execution.
Over-scoping customization before validating architecture fit
Globant notes that customization-heavy efforts can increase delivery timelines and coordination needs, so unclear scope leads to schedule risk. EPAM Systems and Capgemini also show that modernization depth can expand delivery complexity when integration boundaries and architecture choices are finalized too late.
