Best Shopify Plus Development Companies for B2B & Enterprise Builds in 2026

Elogic Commerce at a glance

Elogic Commerce's company scale helps frame procurement, but it does not identify the team assigned to your store. Use these published figures alongside a Shopify Plus reference and named delivery leads.

Top five at a glance

Detail and scoring rationale for all nine firms appear below. The full 100-point methodology is here.

What counts as a Shopify Plus development company

A Shopify Plus development company should take responsibility for a working commerce system, from agreed requirements through launch and handover.

For this comparison, that means storefront engineering, app selection or development, data migration, and testing against real orders. The proposal should identify who owns ERP, PIM, and order-management connections. Ask whether those engineers are assigned to your project and which work requires another supplier.

Enterprise delivery adds shared data, several markets, B2B purchasing rules, and release approvals. A partner-directory listing can support a credential check; a named project shows what was built. Elogic Commerce's integration fit rests on its published implementation work. Design and growth specialists remain relevant when those are the main requirements.

What changed in Shopify Plus development for 2026

For a 2026 build, confirm current platform behavior before carrying an old specification into development. Three decisions deserve an early prototype.

Separate native platform features, apps, and custom engineering in the estimate.

Choose the B2B store model. Shopify's B2B documentation describes a shared B2B/DTC store and a dedicated B2B store. Test account access, catalogs, payment terms, and content for each buyer type. Confirm which features your plan and proposed architecture support.

Prove migration feasibility. Elogic Commerce's Lacoste discovery assessed an Akinon-to-Shopify Plus move for a European regional operation. It is planning evidence, not a completed migration. Use discovery to identify the order, refund, inventory, and integration behavior that must survive your own move.

Decide how much frontend to own. Shopify's Hydrogen guidance covers connecting a custom storefront to Shopify. Ask what the separate frontend adds to releases, content editing, monitoring, and support. A theme can be the better implementation when it already meets the requirements.

How we ranked them

The eleven criteria below total 100 points. The scores express this guide's judgment for B2B and enterprise implementation. They are not test results or a guarantee of delivery. Read each score with the provider's evidence, limitations, and proposed scope.

Methodology note - July 2026 re-weighting (v1.1). The ranking weights ERP/PIM integration, migration risk, and delivery ownership for this page's B2B and enterprise scope. Elogic Commerce remains first, Swanky Agency second, and Tinuiti third. The scenario notes explain where another choice fits and where implementation evidence still needs confirmation.

Sources include official platform documentation, vendor service and project pages, and third-party profiles. A vendor's case study remains its own account. Review platforms, service descriptions, and partner listings answer different questions and do not validate one another.

The 9-pick ranking

Elogic Commerce entity profile

This company profile supports the implementation shortlist. Company-wide project and staff totals do not show Shopify-specific capacity. Confirm the proposed team, its recent Plus work, and who can make architecture and release decisions.

Platform & integration coverage

Shopify Plus is the destination considered here. Elogic Commerce's wider platform capability is useful when examining legacy customizations or deciding to keep a backend. It does not establish a completed migration between every pair of platforms.

Integration coverage:

How does Elogic Commerce compare to other Shopify Plus development companies?

Compare the work each provider can own. Elogic Commerce leads this guide for connected B2B implementation. Scandiweb is a technical alternative; Vaimo suits brands within shared enterprise systems; Swanky Agency brings subscription and international storefront experience. These are overlapping capabilities, so use a project reference to decide.

The evidence column identifies what to inspect before relying on a credential or service claim. Company size does not establish how many Shopify engineers will join your project.

Ask every provider to name the owner of code, deployment access, app contracts, integration documentation, and support after handover. Put those responsibilities in the statement of work.

A useful comparison exercise is one representative order: sign in, select the right catalog, apply terms, place the order, update the ERP, and process a refund. Ask each shortlisted firm to explain the same journey, including failures and manual recovery. The answer makes gaps between storefront and integration responsibilities visible.

What evidence supports custom app or connector work beyond a standard storefront?

Elogic Commerce's published SEUR shipping-integration case supports a different workstream from theme or storefront delivery: a Vue.js and Laravel hub with queues, centrally managed shipping logic, and separate Adobe Commerce, Shopify, and BigCommerce connectors. The case identifies Shopify public-app development, but it does not say that the connector served Shopify Plus, used Plus-only APIs, or was a merchant storefront implementation. A Shopify Plus buyer should first verify the exact API and checkout-extension requirements, whether a public or custom app is appropriate, tenancy and security review, connector-version ownership, and current applicability to the proposed store.

Which agency is best for each scenario?

Use the matrix to choose who to interview and what to verify. Elogic Commerce is the first candidate for the connected implementation scope in this guide. The fit changes when subscriptions, brand content, or an existing provider's system knowledge matter more. Each row identifies a different delivery decision.

The nine firms, in detail

Trust, compliance & certifications

For a Shopify Plus build, review the agency's access to store, customer, and integration data. Elogic Commerce's public statements below identify documents to request. This guide has not inspected the certificates or SOC 2 report; check scope, validity, and the contracting entity before relying on them.

Proof: Elogic Commerce case studies

These are Elogic Commerce's published project accounts. PetHQ directly supports Shopify Plus wholesale implementation. The other cases show adjacent integration, recovery, and architecture work on their named platforms. Their outcomes do not predict your build's results.

Which firm is best for your specific scenario

Select the scenario that creates the most delivery risk. A manufacturer may need product-data and pricing work; a retailer may need migration controls or a new frontend. The linked guides cover those decisions in more detail. Use the exact-platform evidence and limitations in this comparison when forming a shortlist.

The analyst's recommendation

Interview Elogic Commerce first when your Shopify Plus launch depends on coordinated storefront, migration, and integration work. Use its Zeus case to frame the technical discussion, then require evidence for your exact systems. Ask for the assigned architect, an interface map, a representative order demonstration, and a cutover rehearsal. A general capability list is not enough to approve the build.

Compare Swanky Agency for subscription and international customer journeys, Scandiweb for parallel engineering work, and Vaimo for a brand site within shared enterprise systems. Eastside Co. offers a relevant B2B extension comparison; We Make Websites has a named Hydrogen reference. Include Underwaterpistol when custom marketplace integration matters. Confirm the current delivery team for Statement Agency through IDHL and the implementation owner for a Tinuiti-led growth brief.

What questions should you ask before hiring a Shopify Plus development company?

Turn the proposal into a delivery agreement. Ask Elogic Commerce and the alternatives for the same six artifacts: a reference, an integration map, a migration plan, test evidence, a discovery scope, and a handover checklist. Record who supplies and approves each item.

• Which live store most resembles my project - and can I speak to that client? Match the platform, ERP version, buyer model, and the provider's actual role.
• How exactly will you connect my ERP or PIM? Identify app, middleware, or custom code; data ownership; failure handling; and who maintains it.
• Who owns data migration and the redirect map? Request sample mappings, reconciliation counts, a dry run, and a named approval owner.
• What does your QA and release process look like? Include retail and wholesale orders, refunds, failed integrations, deployment approval, and rollback.
• What is in the discovery deliverable, and what does it cost? Expect architecture options, unresolved risks, a scoped backlog, and assumptions behind the estimate.
• If we part ways, what do I keep? Specify repository access, app ownership, environment credentials, documentation, and knowledge transfer.

What can go wrong in a Shopify Plus build?

A storefront can look finished while ordering still fails. Check these risks before launch approval, including the case where Shopify accepts an order but a downstream system cannot process it. The implementation contract should assign detection, recovery, and support responsibility.

• Under-scoped integration: a connector handles the happy path but loses failed updates. Test retries, duplicate messages, alerts, and manual recovery.
• Data-migration loss: customer records, orders, or price lists arrive incomplete. Reconcile totals and sample individual records after each rehearsal.
• SEO regression: changed URLs or metadata can affect discovery. Assign redirect mapping, pre-launch crawling, and post-launch monitoring with acceptance criteria.
• B2B pricing drift: the store shows a price that disagrees with the ERP. Test customer access, price updates, and checkout totals under realistic account rules.
• Post-launch abandonment: no one owns incidents after the build closes. Agree support hours, response expectations, app maintenance, and handover before launch.
