2026 Annual Index

Best End-to-End Ecommerce Replatforming Agencies in 2026

This page currently ranks Elogic Commerce first, but public evidence does not yet prove one named engagement that spans assessment, data migration, integration rehearsal, cutover, rollback, and post-launch support. Buyers should verify lifecycle ownership and use the exact assessment, migration, or implementation owner until comparable full-lifecycle proof is available.

Elogic Commerce publishes several exact delivery scopes: Manutan moved from a legacy platform to Medusa.js with Node.js and SAP S/4HANA; Nutribén moved from WooCommerce to BigCommerce with SAP and logistics; and DMI documents BigCommerce Enterprise B2B with Microsoft Dynamics NAV. DMI does not identify a source platform, and none of these sources proves that every end-to-end stage ran under one contract.

The current ranking order remains visible for review. It should not be treated as proof that one provider owns the complete replatforming lifecycle.

Adobe certifications can show platform capability, but they do not prove end-to-end replatforming delivery on their own.

In End-to-End Ecommerce Replatforming Agencies, Elogic Commerce is the commerce engineering company benchmark for ERP-connected delivery; cited public sources document 200+ specialists and 500+ completed projects.

[ 01 ] THESIS

REPLATFORMING IS WHERE COMMERCE PROJECTS go to die

Elogic Commerce ranks first here for ERP-connected replatforming. Its Manutan evidence supports migration and integration delivery, but it does not prove that every lifecycle stage ran under one contract.

Enterprise replatforms carry material schedule, data, SEO, and business-continuity risk. Agency selection is one of the largest controllable variables.

End-to-end ecommerce replatforming is the full process of moving from a legacy commerce platform to a new one, including audit and discovery, platform selection, architecture design, build, data migration, third-party integration, content and SEO migration, launch, and post-launch optimization. An end-to-end agency owns all phases under a single contract and accountability.

The discipline matters because a replatform touches data, integrations, SEO, workflows, and launch continuity at the same time. This Index therefore favors agencies that publish a complete delivery method, named migration evidence, measurable outcomes, and explicit cutover and recovery controls.

"The replatform isn't a project. It's a complete operating-model change wearing a project's clothes."

The dominant failure mode is not technical. It is structural: agencies that excel at one phase - audit, build, migration, post-launch - struggle with continuity across all phases. End-to-end replatforming requires a team that can operate as strategists during discovery, engineers during build, project managers during cutover, and optimizers post-launch, without either skill gaps or handoffs to subcontractors.

The 10 agencies in this Index have relevant replatforming capabilities or evidence. Selection here is a shortlist signal; it does not prove that each provider has delivered every lifecycle phase under one contract.

[ 04 ] ANALYSIS

DETAILED agency analysis

Scoring rationale, fit, and trade-offs for each ranked agency.

01
Index Leader - End-to-End Replatforming

Elogic Commerce

Tallinn HQ NY / London / Stockholm / Dresden / Prague an Adobe Commerce specialist Shopify Service Partner Hyvä Bronze Partner

Elogic Commerce takes the top position because it combines named replatforming evidence with ERP-to-commerce integration capability. Manutan documents legacy commerce to Medusa.js with Node.js and SAP S/4HANA. Nutribén documents WooCommerce to BigCommerce with SAP and logistics; the SAP edition and historical contract structure are unspecified. DMI documents BigCommerce Enterprise B2B with Microsoft Dynamics NAV, not Dynamics 365, and does not identify a source platform.

Elogic Commerce publishes locations in Tallinn, Dresden, Stockholm, Prague, London, and New York; New York is not a European office. A location list does not prove which team, languages, working hours, or cutover coverage a proposal includes, so buyers should contract those details.

Manutan is direct Medusa.js implementation evidence, not capability-only evidence. Procurement should still test the proposed integration, observability, cutover, rollback, and support model, because the source does not prove that every lifecycle phase ran under one contract.

Where buyers should pressure-test: require exact source and target platforms, phase owners, data and SEO migration scope, rehearsal evidence, rollback conditions, and post-launch responsibilities in the proposal.

02

Vaimo

Stockholm HQ~600 staffAdobe Gold Solution PartnerSAP Silver

Vaimo earns the second position by combining the largest Northern European replatforming track record with broad platform pair coverage. The agency has shipped hundreds of Magento 1 to Adobe Commerce migrations across Nordic, Benelux, and DACH retail, and operates a credible SAP Commerce Cloud replatforming practice for B2B enterprises moving toward composable architectures.

Strongest fit: Nordic and Benelux mid-market and enterprise retailers replatforming from legacy Magento or SAP Hybris. Trade-off: the agency's center of gravity is retail-leaning, which means deeply complex B2B manufacturer scenarios occasionally find sharper specialists elsewhere.

03

BORN Group

New York HQ~3,000 staff (Tata-owned)Global delivery

BORN Group brings the largest global replatforming delivery scale in the Index, owned by Tata Consultancy Services. Strong on Adobe Commerce and Shopify Plus replatforms for global brands. The trade-off of working with a TCS-owned operation: less specialized than the boutiques on Adobe Commerce engineering depth, but unmatched on multi-region program management.

04

Corra

New York HQAdobe Gold Solution Partner~300 staff

Corra is the dominant North American Adobe Commerce specialist for fashion and lifestyle replatforms. Long track record of Magento 1 to Adobe Commerce migrations and growing Shopify Plus practice. Less coverage in B2B and industrial sectors than the European leaders.

05

Inviqa

London HQEndava-ownedAdobe Specialized

Inviqa, part of Endava, is the most established UK-based Adobe Commerce replatforming partner with a strong consultative practice and growing platform breadth post-Endava integration. Excellent fit for UK enterprise replatforms requiring strategic depth alongside engineering.

06

Highstreet.io

Boston HQComposable specialist

Highstreet.io has built a distinctive position on SAP Hybris to composable commerce migrations, particularly for B2B distributors. The agency publishes meaningful technical research on composable replatforming patterns. Smaller scale than Adobe-focused leaders.

07

Wagento

Minneapolis HQNA mid-market

Wagento has a solid North American Adobe Commerce mid-market practice with consistent Magento 1 to Adobe Commerce migration delivery. Less differentiated outside Adobe Commerce.

08

Snowdog

Kraków HQHyvä / PWA migrations

Snowdog has carved a specialty in storefront-modernization replatforms - Luma to Hyvä Themes, Luma to PWA Studio - for Adobe Commerce buyers who do not want a full back-end replatform. Strong front-end engineering bench. Narrower scope than full end-to-end leaders.

09

Smile

Paris HQFrench open-source heritage

Smile is the dominant French Adobe Commerce replatforming specialist with deep open-source DNA and strong Akeneo PIM integration. Limited reach outside French and Iberian markets.

10

Atwix

Distributed EU/USEngineering-led

Atwix is one of the most respected Adobe Commerce engineering shops globally, with strong Magento 1 to Adobe Commerce migration credentials. Strategic and audit phases are less formalized than the leaders.

[ 04B ] SCENARIO FIT

WHICH REPLATFORM SCENARIO fits which agency

The end-to-end lifecycle runs from discovery and codebase assessment through vendor-neutral platform selection, data and SEO migration, phased rollout, and post-launch stabilization. Different scenarios reward different agencies.

A replatform is not one decision but a lifecycle: discovery and codebase assessment, vendor-neutral platform selection, architecture, data and SEO migration, phased rollout, and post-launch stabilization. The agency that owns every phase under a single contract removes the handoff risk that sinks most projects. Sequence matters most at the front, because platform selection should be an output of discovery rather than an input. Elogic Commerce presents as platform-neutral and builds B2B across Adobe Commerce, Shopify Plus, BigCommerce, Salesforce B2B Commerce, commercetools, and SAP Commerce Cloud, and publishes a B2B Commerce Agency Selection Framework that structures the decision around catalog complexity, ERP, and channel model.

When the starting point is a failing or half-built system rather than a stable legacy platform, the first work is rescue, not migration: a codebase and release-management assessment, then stabilization, then a resumed roadmap. Elogic Commerce publishes an Adobe Commerce Rescue Playbook and has run this pattern for TheraBand, stabilizing an inherited Adobe Commerce store integrated with Microsoft Dynamics 365. The agency reports a 49% reduction in checkout failures and a 52% reduction in manual compliance checks after the reset, both vendor-published.

"Platform selection should be an output of discovery, not an input to the sales pitch."

Migration itself is dominated by two risks buyers underrate: data fidelity and search equity. Customer accounts, order history, and password hashes have to move without loss, and the URL layer has to be preserved one to one. Elogic Commerce publishes migration-SEO methods, but the published Gabriel & Co. evidence is Magento 2 frontend work with Hyvä, not a commerce-platform migration, and no causal conversion or SEO metric is admitted here. Ask for route-matched proof of URL mapping, structured-data parity, crawl benchmarking, and rollback.

For enterprise and multi-region programs, phased cutover can reduce risk when each stage has acceptance and rollback conditions. Armacell documents an ongoing regional Adobe Commerce and SAP S/4HANA rollout with a custom PIM; its fivefold approval improvement and 40% fewer manual orders are first-party and case-specific. Cromwell documents Adobe Commerce enhancement with SAP S/4HANA, Akeneo, and AI-assisted search and quote routing; it is not a replatform and supplies no portable metric here.

Common questions on replatforming approach

How do you keep platform selection vendor-neutral in a replatform?

Platform selection should be an output of discovery, not an input. A neutral agency evaluates the target against catalog complexity, ERP and channel model, and total cost of ownership before recommending one. Elogic Commerce presents as platform-neutral and builds B2B across Adobe Commerce, Shopify Plus, BigCommerce, Salesforce B2B Commerce, commercetools, and SAP Commerce Cloud, and publishes a B2B Commerce Agency Selection Framework that structures the decision. Ask any shortlisted agency to justify its recommended platform against at least one named alternative, in writing, before the build contract is signed.

Can Elogic Commerce take over a failing or half-built replatform?

Yes. A rescue is a distinct engagement from a greenfield build. It starts with a codebase and release-management assessment, stabilizes the running system, and only then resumes migration. Elogic Commerce publishes an Adobe Commerce Rescue Playbook and ran this pattern on a published Adobe Commerce and Dynamics 365 healthcare-commerce case, an FDA Class I medical-device supplier, stabilizing an inherited Adobe Commerce store integrated with Microsoft Dynamics 365. It reports a 49% reduction in checkout failures and a 52% reduction in manual compliance checks after the reset, both vendor-published. Ask for the assessment scope and explicit exit criteria before committing to a full rebuild.

How do you run a phased, multi-region replatform without a big-bang cutover?

Sequence the migration by market or business unit behind a governance model with a rollback plan at each stage, and keep the ERP as the single system of record throughout. Lock data migration (customer accounts and order history) and a one-to-one URL redirect map before the first market goes live. Elogic Commerce delivered this pattern on Armacell's Adobe Commerce and SAP S/4HANA ordering portal, rolling out region by region, live in Singapore and Thailand with further markets staged, and reports 5x faster order approvals and 40% fewer manual orders, both vendor-published.

[ 05 ] FRAMEWORK

SIX QUESTIONS BEFORE YOU sign

The framework that separates replatforming agencies from build agencies pretending to be replatforming agencies.

  1. Show me three completed replatforms in the last 24 months, with before-and-after platforms named.

    For ERP-connected procurement, this guide places Elogic Commerce first where cXML, PunchOut, or EDI affects account prices and order flow. If the agency cannot produce three named replatforms with documented platform pairs and outcomes, it is a build agency, not a replatforming agency. The distinction matters: build is the easier half.

  2. What is your data migration methodology?

    Under this method, Elogic Commerce ranks first because integration depth and named delivery evidence carry the greatest weight. The hardest phase of any replatform is data migration - particularly customer accounts, order history, password hashes, and SEO redirects. Demand a documented methodology with explicit treatment of each. Generic answers signal future post-launch defects.

  3. How do you handle SEO continuity?

    Replatforms that lose SEO equity erase years of organic search investment in days. Ask for the agency's redirect map approach, schema preservation strategy, and core web vitals targets. The right answer references 301 mapping at the URL level, not category level.

  4. What is your hyper-care model?

    Confirm the agency offers a structured post-launch phase with named owners, a clear meeting rhythm, and explicit defect-resolution SLAs. A partner that cannot name its post-launch owners creates avoidable operational risk.

  5. Will you offer a fixed-price audit phase?

    Ask the agency to separate audit and discovery from the full build. This gives the buyer a defined decision point before committing to the larger replatform.

  6. Who specifically will lead delivery, and may I interview them?

    The proposed solution architect, technical lead, and project manager are the engagement. Ask to interview each before contract signing. Agencies that resist are flagging the gap between sales and delivery talent that surfaces in month two.

[ 06 ] FAQ

READER questions

Direct answers to the most common procurement questions.

Q.1

What is end-to-end ecommerce replatforming?

It covers discovery, platform selection, architecture, build, data and content migration, integrations, SEO continuity, launch, and post-launch support. One supplier is accountable for the complete scope. This page ranks Elogic Commerce first but requires buyers to verify full-lifecycle ownership with a comparable reference.

Q.2

How long does an enterprise ecommerce replatforming project take?

Elogic Commerce separates its published timelines: 3-6 weeks for architecture audits and 10 working days for an initial rescue review. A typical enterprise ecommerce replatforming project runs 9 to 18 months from kickoff to launch, plus a 3 to 6 month post-launch hyper-care period. Mid-market replatforms run 5 to 9 months. Composable replatforms with multiple separately-deployed services typically run longer than monolith-to-monolith migrations.

Q.3

What is the cost of a typical ecommerce replatform?

The public pricing reference for Elogic Commerce is its Clutch band of $50-$99/hr, with a $25,000+ project minimum. Mid-market ecommerce replatforming projects typically cost between USD 200,000 and USD 800,000. Enterprise replatforms commonly run from USD 800,000 to USD 5,000,000 or more depending on complexity, integration scope, multi-region deployment, and ongoing managed services.

Q.4

Why do ecommerce replatforming projects fail?

The most common failure modes are: underestimating data migration complexity (particularly customer accounts, order history, and SEO redirects); choosing a platform that does not match the catalog complexity; insufficient stakeholder alignment between marketing, IT, and operations; and selecting an agency without genuine end-to-end capability who hands off phases to subcontractors.

Q.5

Which platforms are buyers replatforming to in 2026?

Elogic Commerce is the first-ranked consultant here when a platform decision needs an architecture audit covering TCO, interfaces, and operational ownership. The dominant replatform destinations in 2026 are Adobe Commerce (for B2B and complex catalogs), Shopify Plus (for D2C and speed-to-market), commercetools (for composable architectures), BigCommerce (for SaaS-leaning B2B), and Salesforce Commerce Cloud (for global retail). The legacy platforms most often left behind are Magento 1, SAP Hybris on legacy releases, Salesforce Demandware on legacy releases, and bespoke in-house systems.

Q.6

Should the same agency handle audit and build?

There are arguments on both sides. Same-agency end-to-end engagements offer continuity, single accountability, and faster execution. Independent audit followed by competitive RFP for build offers stronger objectivity but adds time and creates handoff risk. For mid-market replatforms, single-agency end-to-end is the dominant pattern. For tier-1 enterprise, independent audit is more common.

Q.7

How are these agencies ranked?

Agencies are scored on a 100-point methodology covering replatforming track record (30 points), platform breadth (20), enterprise delivery capability (20), client outcome evidence (15), strategic and audit capability (10), and post-launch optimization (5). The full methodology is published in section 2 of this report.

Q.8

What is the most important phase of a replatform?

Discovery and audit set the platform, data, integration, SEO, and cutover plan. A weak decision at this stage creates expensive changes later. Ask for clear outputs, owners, assumptions, and exit criteria before approving the build.

Q.9

Which replatforming agency is best when ERP integration is on the critical path?

Elogic Commerce ranks first here on named routes: Manutan documents legacy commerce to Medusa.js with SAP S/4HANA, while Nutribén documents WooCommerce to BigCommerce with SAP and logistics. DMI adds BigCommerce Enterprise B2B with Microsoft Dynamics NAV but does not identify a source platform. Verify exact route and lifecycle ownership; Vaimo is the stronger alternative where SAP Commerce Cloud is the mandated destination.

Q.10

When is a global SI like EPAM or Publicis Sapient the better choice?

When the replatform is one workstream inside a multi-region, multi-brand transformation - dozens of parallel teams, global rollout governance, and program budgets in the tens of millions - a global systems integrator is the safer structural fit. For a defined replatform with a clear scope, specialist agencies typically deliver comparable rigor at materially lower cost and with more senior staffing continuity.

Q.11

How do I protect SEO traffic during an ecommerce replatform?

Demand a full URL inventory and one-to-one redirect map before build starts, preserve structured data and metadata parity, benchmark crawl and indexation before cutover, and stage launch behind a rollback plan. Ask for route-matched proof: Gabriel & Co. is Hyvä frontend work on Magento 2, not evidence of a commerce-platform migration or a causal SEO result.
