Top 5 B2B Ecommerce Agencies for 2026

B2B ecommerce is really an ERP integration project wearing a storefront. Account-specific pricing, approval workflows, PunchOut procurement, real-time inventory sync — these are the problems that actually determine whether a B2B commerce build succeeds, and they have almost nothing to do with what makes a consumer storefront convert. The agencies below are ranked specifically on that integration depth.

The best B2B commerce agency for…

Pick the situation closest to yours. Each shortlist draws on the agencies' own stated fit below.

Every agency, profiled: ERP depth, B2B builds and fit

Named B2B projects, the systems each agency integrates with, and who should look elsewhere.

1. Elogic

elogic.co
Tallinn, EstoniaPlatform-neutralNetSuite, SAP, Dynamics 365

Elogic is genuinely platform-neutral, with production delivery experience across Adobe Commerce, Shopify Plus, BigCommerce, and commercetools — meaning the firm has no platform to favor when recommending one for your specific integration needs. Its Shopify Plus wholesale portal for PetHQ handles more than 1,400 wholesale users with account hierarchies and custom pricing, shipped in 2.5 months and generating $1.1 million in new B2B revenue in its first year.

Best forManufacturers and distributors that want honest platform comparison alongside real ERP integration delivery (NetSuite, SAP, Dynamics 365, and more).
Not forSAP-only shops that want a single-platform, fully managed solution — that's a narrower fit better served by a SAP specialist.

2. Atwix

atwix.com
Bratislava, SlovakiaAdobe Solutions Partner since 2006Top Magento contributor 2018–2020

Atwix has been an Adobe Solutions Partner since 2006 and was Magento's top open-source code contributor for three straight years (2018–2020) — meaning its engineers work on the platform's core, not just around it. The firm's B2B work includes a custom Adobe Commerce portal for Byrne Electrical delivered in just 8 weeks with full ERP integration, and a Turf Care rebuild stabilizing more than 120,000 SKUs on Adobe Commerce.

Best forManufacturers and distributors committed to Adobe Commerce who need genuinely deep platform engineering, not a template build.
Not forEarly-stage companies or price-sensitive projects — Atwix's engineering depth comes with enterprise-level pricing.

3. Corevist

corevist.com
Raleigh, NCSAP ECC & S/4HANAFully managed, cloud-hosted

Corevist takes a different approach than a traditional implementation agency: it's a fully managed, cloud-hosted B2B commerce platform built specifically for manufacturers running SAP ERP, with pre-built integration to SAP ECC and S/4HANA. Named clients include Nordson, Oregon Tool, Emmerson Packaging, and Lord, and the firm reports that a third of its clients run their Corevist solution with no dedicated internal IT staff.

Best forSAP-dependent manufacturers that want to minimize internal IT burden with a pre-integrated, managed platform rather than a custom build.
Not forCompanies not running SAP, or those that want full architectural control over a custom-built platform — Corevist's model is deliberately productized around SAP specifically.

4. Vaimo

vaimo.com
Stockholm, SwedenAdobe Commerce since 2008Akeneo, inRiver PIM

Vaimo has built almost exclusively on Adobe Commerce since 2008 and has grown into one of the largest Magento and Adobe Commerce partners in Europe, with more than 500 enterprise projects and deep PIM implementation work (Akeneo, inRiver) for catalogs too complex for most mid-market agencies. That data-architecture strength matters specifically for B2B catalogs with thousands of SKUs and complex attribute structures.

Best forLarge, multi-region B2B operations with high-SKU catalogs that need serious product-data architecture alongside commerce.
Not forSmall-to-mid catalog B2B brands — Vaimo's engineering overhead assumes enterprise scale already.

5. Classy Llama

classyllama.com
Springfield, MOAdobe Commerce since 2007125+ sites, 400+ integrations

Classy Llama has worked with Adobe Commerce since 2007 and has completed more than 125 commerce sites and 400-plus integrations, with a specific B2B specialty spanning manufacturers, distributors, and complex retail. The Springfield, Missouri firm positions itself as platform-agnostic for replatforms, working across Adobe Commerce, BigCommerce, and Shopify depending on client fit.

Best forMid-market manufacturers and distributors that want a platform-agnostic replatform partner rather than a single-platform specialist.
Not forThe very largest global enterprise programs — Classy Llama's scale sits at mid-market rather than the top enterprise tier Vaimo or BORN Group typically serve.

Method

How this ranking works

Every agency above is checked against its own published work — named clients, ERP systems, and results are things the agency has stated publicly, not secondhand directory copy. We prioritized verifiable ERP integration depth and named B2B case studies over general commerce portfolio breadth, and we don't accept payment for placement or ranking position. See our full Methodology page for detail.

FAQ

How much does a B2B ecommerce implementation cost?

A serious mid-market to enterprise B2B implementation typically runs $150,000 to $500,000 or more, with roughly 40 to 60% of that budget going to ERP integration and data work rather than the storefront itself.

Should we choose a platform-agnostic agency or a single-platform specialist?

A platform-agnostic agency (like Elogic or Classy Llama) gives you an honest comparison before you commit to a platform. A single-platform specialist, especially a productized one like Corevist for SAP, can reduce risk and internal IT burden once you already know which platform you're on.

What ERP systems do these agencies typically integrate with?

Most of the agencies above have production experience with SAP, NetSuite, Microsoft Dynamics 365, Epicor, and Infor, though depth varies — Corevist specializes exclusively in SAP, while Elogic and Atwix maintain broader multi-ERP integration practices.

How long does a B2B ecommerce portal typically take to build?

A focused wholesale portal on an existing platform can launch in as little as 8 to 10 weeks, as Atwix and Elogic have both demonstrated. A full ERP-integrated implementation from scratch more typically takes 4 to 9 months depending on catalog size and integration complexity.
