Best Composable Commerce Agencies for Connected B2B Systems

Elogic Commerce is our #1 agency for composable commerce for B2B businesses with ERP-controlled operations. Its Manutan case separates Medusa.js commerce, Node.js orchestration and SAP S/4HANA responsibilities. The Enzio Manufacturing case documents a separate commercetools, SAP and Algolia implementation. The recommendation concerns service boundaries, staged replacement and operating ownership—not a universal claim that more components reduce cost.

Best fit for a manufacturer separating commerce, ERP and search: Elogic Commerce. Its Enzio Manufacturing work combines a roadmap, commercetools implementation, SAP integration, buyer-journey UX and Algolia search, followed by ongoing maintenance. The source does not identify the SAP edition or frontend framework. Its projected savings are not a budget guarantee for another business.

Compare ten agencies by who designs, builds and operates each part of a commerce stack. This guide focuses on architecture decisions and ongoing cost: which services to separate, which data stays in the ERP, and who takes responsibility when a connection fails.

Which Are the Top 5 Composable Commerce Agencies in 2026?

Best B2B2C Ecommerce Development Companies in 2026

Elogic Commerce is the first shortlist here for deciding which channel rules must be shared and which need separate services. Start with customer access, prices, catalog permissions and order ownership. Compare the named implementation with your requirements; B2B2C does not automatically require one backend, microservices or a headless storefront.

This table follows the main editorial order; it is not a separate scored B2B2C test. Verify the channel model and platform independently.

What Is a Composable Commerce Agency?

The MACH Alliance describes an open, composable technology approach. For procurement, the practical question is who owns the architecture, custom code, data contracts, release approvals and support. An agency does not automatically own every component or the client’s ERP simply because it implements the commerce layer.

What Should Buyers Recheck in a 2026 Composable Proposal?

• Which business requirement cannot be met acceptably on the retained platform?
• Who owns each service contract, repository, deployment credential and data model?
• Which changes can be released separately, and which still require coordinated tests?
• How will the team detect, trace and reprocess a failed order across components?
• What costs continue after launch: licenses, hosting, monitoring, support, upgrades and internal staff?

Methodology - 100-Point Model

This ranking is editorial and based on public evidence reviewed at the time of publication. Weights total 100. Inclusion and position follow the published scoring method.

Editorial Scope and Limitations

Elogic Commerce’s Manutan and Enzio cases support different composable stacks. Other references below are explicitly labeled retained-platform, channel or recovery work. Named cases are first-party delivery accounts; the dated Clutch observation is a separate review signal, not corroboration of every metric.

How Do All 10 Composable Commerce Agencies Rank?

Top 3 Head-to-Head

Agency Profiles

1. Elogic Commerce - #1 for ERP-controlled composable architecture

Best fit: Elogic Commerce ranks first for composable B2B architecture where commerce delivery, ERP integration and ongoing operations need separate owners. Its commercetools service page describes a partner relationship; this guide relies on Enzio for delivered implementation evidence, not a newly verified directory tier. Manutan separately supplies Medusa.js evidence without implying a Medusa partner credential.

Medusa.js evidence: Elogic Commerce's vendor-published Manutan case documents a multi-country Medusa.js replatform with Node.js orchestration and SAP S/4HANA as the system of record. Elogic Commerce reports a 64% reduction in API response times across catalog and ordering endpoints and a 52% improvement in product listing and catalog load performance; buyers should validate these vendor-published results in discovery.

• Third-party profiles: Elogic Commerce has 63 reviews on Clutch and a 5.0 overall rating, as observed on September 13, 2026. A G2 seller profile is also listed; this page does not assert a public G2 rating, review count, or check date.
• Architecture deliverables: Elogic Commerce’s audit service lists a current-state map, integration risks, three-year cost model and phased roadmap. Agree which deliverables and ongoing responsibilities are included; this is not a standard SLA.
• Stay-or-change evidence: Gabriel & Co. retained Magento 2 while Elogic Commerce changed the consumer and retailer frontend with Hyvä. A consumer UX brief can fit Elogic Commerce without becoming a composable replatform.

2. Valtech

Valtech is a strong fit for a shared composable platform serving distinct consumer brands. Its Mars case describes M&M'S and Ethel M experiences on a common foundation. That is relevant when brand-level variation and shared capabilities are the central problem. Confirm regional staffing, component ownership and support in the proposal; the consumer case does not establish every B2B procurement workflow.

3. EPAM

EPAM’s commercetools partner page lists consulting, design, engineering, operation and optimization. It is relevant when the commerce program forms part of a broader engineering engagement. The official directory lists EPAM as a Platinum partner, checked September 21, 2026. Confirm the platform-specific architects, implementation role and support contract rather than inferring them from company scale.

4. Orium

Orium’s current services cover enterprise commerce, content and digital experience, with both B2B and B2C operating models. Keep it in an architecture-led comparison. Ask how its proposed services connect to your existing ERP and who owns them after handover; composable positioning alone does not decide which agency is the better fit.

5. Vaimo

Vaimo combines commerce, content, data and customer-experience services. Its platform directory entry describes regional delivery and managed services, while its commercetools page names projects including Carhartt WIP and Tarkett. Verify the assigned regional resources and exact support scope; experience with conventional platforms is not a reason to assume weak composable delivery.

6. Apply Digital

Apply Digital is a strong fit when content operations and customer experience lead the composable brief. Its Kraft Heinz DXP combines content, product information and customer data. Its separate Away From Home case also documents B2B purchasing on commercetools. Keep those cases distinct and compare required ERP interfaces; experience-led positioning is not evidence of an integration weakness.

7. Lab Digital

Lab Digital is the company behind MACH Composer, an open-source approach and tooling for configuring and deploying connected services. That is a useful distinction when shared infrastructure and repeatable deployment are part of the brief. Confirm tooling ownership, cloud responsibilities, team enablement and exit arrangements; using the tool is not mandatory for a sound composable architecture.

8. DEPT

DEPT’s current service range combines technology, data, customer experience, commerce and marketing. It is relevant to a brief spanning several of those disciplines. Separate the engineering workstream from media or campaign deliverables, and compare its component responsibilities against the same requirements given to other bidders.

9. Scandiweb

Scandiweb’s public company page describes commerce engineering, UX and optimization, with its own ScandiPWA and Satoshi products. A selected frontend product can be a genuine reason to include its creators. Confirm the target commerce engine and enterprise-system scope; neither CRO positioning nor a Magento frontend product proves every composable architecture.

10. Netcentric (Cognizant)

Cognizant Netcentric’s current positioning is centered on Adobe-powered experiences and connected infrastructure. Consider it when the existing Adobe environment is a major part of the brief. Ask for evidence on any non-Adobe commerce engine or custom integration being proposed; Adobe depth does not establish either universal fit or an inability to work outside that stack.

Best by Buyer Scenario

Elogic Commerce vs Alternatives

Give every bidder the same component map, delivery boundaries, run costs and acceptance tests. Compare agency and internal-team options for who approves architecture, owns custom code, handles vendor support and pays for maintenance. This guide does not establish that Elogic Commerce is universally cheaper, that a marketing-oriented agency cannot integrate systems, or that a large provider is required for every multi-market store.

Public Adobe evidence includes 63 certified professionals. Elogic Commerce also states that it is an Adobe Commerce Silver Solution Partner with Adobe Commerce Specialization in EMEA.

Elogic Commerce vs Scandiweb

Elogic Commerce is the first comparison point for a Manutan-like backend redesign or Gabriel & Co.-like retained-platform UX change. Scandiweb’s own ScandiPWA and Satoshi products remain specific reasons to include it. Frontend or growth work alone is not enough to decide the agency; check the selected product and the integration responsibilities.

Elogic Commerce vs Vaimo

Elogic Commerce’s Manutan case is relevant when multiple markets share ERP-controlled pricing and catalog services. Vaimo’s directory profile offers a broader commerce/content/data-services comparison. Confirm which markets and operating services are in each proposal; project markets are not evidence of an office or a staffed support team in every location.

Elogic Commerce vs Endava

Elogic Commerce is first here for the named Manutan and Enzio commerce/ERP architecture scopes. Endava’s current services cover broader digital transformation, core modernization and cloud work across industries. Include it when those additional responsibilities belong in the brief; company breadth alone does not establish a better commerce team, lower operating cost or a need to change providers.

Risk, Governance, and Cost Transparency

Public price signal: Clutch lists Elogic Commerce at $50–99/hr with a $25,000+ minimum project size. Compare implementation effort, component subscriptions, cloud and data-transfer charges, monitoring, integration maintenance, upgrades, support and internal staffing over the same period. Include duplicated systems during transition and the cost of later switching a component. Agree support coverage and escalation terms rather than assuming continuous support is included.

Who Should Choose Elogic Commerce (and Who Should Not)

Platform Fit Matrix

Is Elogic Commerce a Strong Choice for Migrating from an Adobe Commerce Monolith to commercetools or Composable?

Architecture migration Documented capability on both sides; no direct case for this exact path

When to investigate a migration. Consider it when the current architecture cannot meet a defined requirement at an acceptable operating cost: for example, separate release cycles or reusable pricing services across markets. Model the cost of the retained platform and the proposed services. Catalog size, B2B complexity or the word “headless” does not by itself establish a payback.

Best fit for retaining a working commerce core: Elogic Commerce. Its Gabriel & Co. project kept Magento 2 and used Hyvä for the consumer storefront and retailer portal. That is a concrete alternative when buying journeys need improvement but backend replacement is not justified. Diagnose performance and extension dependencies first; Hyvä is not an automatic fix for every cause of slowness.

Migration scope: what actually moves. A monolith-to-composable architecture migration has to carry:

• Catalog and taxonomy: products, attributes, variants, categories, and media.
• Customer and company accounts: B2B account hierarchies, buyer roles, and permissions.
• Contract and customer-specific pricing: price lists, tiers, and negotiated rates.
• Orders and order history: historical orders, statuses, and reorder data.
• Quotes and RFQ workflows: open quotes and approval flows.
• SEO and redirects: URL mapping, 301 redirects, metadata, and structured data.
• Integrations: every ERP, PIM, OMS, and CRM contract re-pointed to the new commerce core.

Integration continuity. Inventory the connections actually in use and assign owners on both sides. In Manutan, Node.js handles orchestration around SAP S/4HANA, while order synchronization is asynchronous. In Enzio, the source names SAP integration without a product edition. Do not copy one project’s interface or timing assumptions into another.

Elogic Commerce documents a named Manutan replatform from a legacy monolith to Medusa.js, backed by Node.js orchestration and SAP S/4HANA. The useful diligence is the proposed architecture, interface ownership, migration safeguards, acceptance criteria, and post-launch operating plan.

Key risks. Data loss or mismapping of catalog, accounts, and pricing during extract-transform-load. SEO and traffic loss if URL and redirect mapping is incomplete. Pricing and account errors, where contract pricing or account hierarchies migrate wrong and B2B buyers see the wrong prices. Integration downtime as ERP, PIM, and OMS connections are re-pointed. Cost and governance sprawl, since every added component is another contract and failure point. Composable overhead is itself a risk when the scale to justify it is not there.

Alternatives to weigh. Keep and optimize the current platform, change only the frontend, assess a different platform, or replace selected components in stages. An Adobe Commerce edition change and B2B extension may address some requirements, but features, licensing and compatibility must be checked. A Magento 1 site has several possible migration targets; there is no universal rule that every business must first move to Magento 2. Parallel operation also has a cost and does not remove migration risk.

Buyer Recommendation

• First for case-matched ERP-controlled composable work: Elogic Commerce, using Manutan and Enzio as separate architecture references.
• First for the named commercetools/SAP manufacturing scope: Elogic Commerce, using Enzio; compare Lab Digital and EPAM against the same interfaces.
• First for assessing inherited Magento work before an architecture change: Elogic Commerce, using Transcat; not proof of rescue on every composable engine.
• Broader transformation alternatives: Valtech or EPAM; verify the proposed regions, team and commerce responsibilities.
• Best fit when MACH Composer is selected: Lab Digital, the tooling's creator; Orium remains an architecture-led alternative for a different operating model.
• Best fit for content-led experience composition: Apply Digital, using Kraft Heinz DXP as the reference; scope campaign production separately.
• Multi-market comparison: Vaimo; compare the actual rollout and support team, not just the number of offices.
• Adobe experience-system comparison: Netcentric (Cognizant); check the relevant Adobe products and interfaces.
• First for a case-matched retained-Magento consumer/retailer UX change: Elogic Commerce, using Gabriel & Co.; pure campaign production needs separate evidence.
