Leading B2B Ecommerce Agencies

The B2B ecommerce agency market has a pattern worth understanding before you shortlist a partner.

Most agencies that call themselves B2B specialists fall into one of two camps. Some are implementation shops that build the storefront and hand it back. Others are marketing agencies that know how to drive traffic but do not fully understand how procurement workflows, buyer permissions, pricing rules, ERP data, and account-based purchasing actually operate.

The leading B2B ecommerce agencies either span both sides or specialize so precisely in one area that the depth alone justifies the narrower scope.

What separates a true B2B ecommerce agency from the broader ecommerce agency market is where the work begins. A generalist usually starts with the brief, the design direction, and the front-end customer experience. A genuine B2B ecommerce specialist starts with the ERP, pricing structure, buyer role hierarchy, customer-specific catalogs, and order workflow before a single wireframe is drawn.

That sequence matters. It determines whether the platform actually serves procurement teams, sales reps, distributors, and business buyers, or simply looks like it should.

The agencies below represent what leading B2B ecommerce agencies look like: implementation-first partners, marketing-led growth agencies, and full-service teams across North America, the UK, and global markets.

Where B2B Ecommerce Investment Breaks	What It Usually Means
Platform launched but buyers still call sales	Self-service UX doesn’t match how procurement actually works
Marketing drives traffic that doesn’t convert	Campaigns built for B2C buyer behavior, not B2B procurement cycles
ERP and storefront report different numbers	Integration was bolted on after launch, not designed in
CAC unknown at the account level	No CRM-to-marketing attribution connecting spend to contracts
Revenue growing but margin declining	Acquisition cost rising faster than account lifetime value

Top 10 Leading B2B Ecommerce Agencies

1. SeedX

Full-funnel B2B ecommerce growth connecting paid acquisition, customer data, and margin reporting into one operating system.

Why they’re on this list: SeedX B2B ecommerce agency is built specifically for mid-market B2B ecommerce brands where marketing channels, CRM data, and financial reporting have never been made to agree with each other.

Strength: Anchors paid media, lifecycle tactics, and analytics to contribution margin rather than misleading platform-level ROAS, giving executives an accurate view of true bottom-line profit.
Platform competencies: Shopify, HubSpot, Salesforce, and Klaviyo ecosystems, with cross-channel attribution and CRM data synchronization
Marketing scope: Full-funnel growth, technical SEO, content strategy, and multi-channel acquisition, with every initiative tied directly to backend performance metrics and pipeline contract value.
Not a good fit if you only need isolated IT fixes or low-budget, standalone design tweaks.

Right call if: acquisition and retention are siloed, marketing spend can’t be connected to account-level CAC, or leadership is making channel allocation decisions based on conflicting dashboards.

2. CQL

Unified commerce agency combining platform engineering, growth marketing, and retail/B2B experience design on Salesforce, Shopify Plus, and BigCommerce.

Why they’re on this list: CQL has 30+ years of commerce delivery and holds Shopify Platinum Partner status following their acquisition of Riess Group in September 2025, making them one of the deepest unified commerce agencies in the Shopify ecosystem.

Strength: One of the few agencies with documented delivery at the intersection of B2B and unified commerce (online and in-store on the same platform), with Wolverine Worldwide’s 14-brand, 70-site, 13-country deployment in 18 months as a reference-point engagement
Platform capabilities: Salesforce Commerce Cloud, Shopify Plus, BigCommerce; integrations across CMS, OMS, PIM, and ERP systems
Marketing scope: Growth marketing, commerce analytics, CRO, performance optimization, and ongoing strategy alongside platform delivery
The Catch: CQL’s primary track record is in retail and DTC; B2B manufacturers and distributors with complex procurement workflows should verify alignment during initial screening.

They’re a strong fit for mid-market and enterprise brands looking to consolidate platform development and growth marketing under one roof. Hire them if you need to power B2B wholesale, retail, and DTC channels from a single, shared infrastructure.

3. Americaneagle

Global full-service digital agency serving manufacturers, distributors, associations, and enterprise B2B brands across development, ecommerce, and digital marketing at scale.

Why they’re on this list: Founded in 1978 and employing 800+ across offices in Chicago, Dallas, London, and Sofia, Americaneagle.com has delivered 12,000+ digital solutions ranging from Fortune 500 programs to B2B manufacturer portals, with BigCommerce B2B Excellence Partner of the Year recognition and 100+ BigCommerce certifications.

Strength: They deploy across Shopify, BigCommerce (Elite), Adobe, Salesforce, OroCommerce, and Sitecore (2025 Partner of the Year), with an in-house integration team that connects nearly any mainstream ERP, CRM, or POS system.
Platform competencies: Platform-agnostic across all major commerce platforms with a specialized ERP integration team built specifically for B2B and hybrid programs
Marketing scope: SEO/GEO/AEO, digital marketing, email, content, paid media, and AI strategy alongside platform delivery
The Catch: Their operational sweet spot is high-complexity, high-budget corporate programs. If your B2B project is on the leaner side, you might find a better cultural fit and more focused attention with a nimbler, boutique shop.

Right call if: a manufacturer, distributor, or enterprise B2B brand needs one partner capable of handling web development, ecommerce, hosting, post-launch support, and digital marketing at significant scale, without managing multiple specialist vendors.

4. Xngage

Purpose-built B2B ecommerce growth agency for manufacturers, distributors, and wholesalers, with the largest Optimizely development practice in the market

Why they’re on this list: Xngage has completed 70+ B2B ecommerce implementations exclusively for manufacturers, distributors, and wholesalers, holds 2024 Optimizely Commerce Partner of the Year, and is the largest Optimizely development agency globally, with named clients across electrical, plumbing, and industrial distribution including Famous Supply, Mayer Electric, PACE Supply, and Werner Electric.

Strength: Sole focus on B2B: no DTC clients, no consumer brand work. Every implementation is for a manufacturer or distributor, which means ERP integration patterns (Epicor, P21, SAP, Acumatica, Infor, Dynamics 365), PunchOut, IDEA Connector, and B2B UX aren’t learned on the job
Platform competencies: Their deployment capabilities cover BigCommerce, OroCommerce, Virto Commerce, and Znode architectures, alongside specialized Akeneo PIM implementations and Gold Partner status with Optimizely Configured Commerce.
Marketing scope: SEO, paid search, display, GA4 analytics, and performance reporting as digital growth services layered onto implemented platforms
The Catch: They are an engineering powerhouse first. Their marketing services are built to support the platforms they deploy rather than drive standalone, aggressive growth campaigns. If your primary objective is customer acquisition rather than heavy-duty backend development, you will find deeper marketing benches elsewhere.

Right call if: a manufacturer or distributor needs a B2B specialist agency with a decade of vertical experience, complex ERP integration, and a platform recommendation process that isn’t driven by partner commissions.

5. Brilliance Business Solutions

A veteran B2B commerce and digital growth agency specializing in ERP-connected storefronts for mid-market industrial operations.

Why they’re on this list: Operating out of Milwaukee since 1998, they built their reputation by solving a specific headache. They connect digital storefronts to complex back-office systems for mid-sized firms that cannot justify an enterprise-sized IT budget. They back this up with certified BigCommerce and Optimizely partner credentials.
Strength: Pure operational practicality. They specialize in building replacement parts catalogs, dedicated sales rep portals, and tight ERP syncs for mid-market manufacturers who need heavy-duty functionality without the massive enterprise scale price tags.

Platform competencies: BigCommerce (B2B edition specialist), Optimizely Configured Commerce, with documented ERP integration across back-office systems for manufacturing and distribution
Marketing scope: Digital marketing, search marketing, ecommerce growth strategy, and AI-powered optimization alongside platform delivery
The Catch: Mid-market in orientation and scope; brands at the enterprise end of complexity (multi-ERP, multi-region, Fortune 500 governance) will run into capacity ceilings. The agency’s strength is in making B2B commerce work for companies that don’t have Salesforce-level IT budgets

Right call if: a mid-market manufacturer or distributor needs an ERP-connected B2B storefront and ongoing digital marketing support from an agency with deep B2B manufacturing context and pricing that reflects mid-market reality.

6. Rixxo

UK B2B ecommerce agency for manufacturers, wholesalers, and distributors, built by former ecommerce retailers with a proprietary Shopify-Orderwise integration product for UK wholesale

Why they’re on this list: Rixxo has operated since 2012 with B2B ecommerce as their primary positioning, not a service line added to a DTC practice, and built a productised Shopify-Orderwise integration (Shopwise) specifically for UK wholesalers because they’d solved the same credit control, trade pricing, and stock sync problem enough times to warrant a product rather than a custom build each time.

Strength: The Shopwise product is specific: a Shopify-Orderwise integration with credit limit enforcement, trade-specific pricing, and stock synchronisation built in, which is a materially different starting point than building the same integration from scratch. Their Magento B2B wholesale package starts at £25,000 with a known extension stack
Platform competencies: Shopify (B2B), Adobe Commerce/Magento B2B, with ERP and WMS integration experience across Orderwise, SAP (via middleware), and other UK distribution systems
Marketing scope: B2B marketing, ecommerce consulting, platform selection, integrations, and growth support
Caveat: Mid-market scale with a capacity ceiling below enterprise agencies; not the right call for brands needing Adobe Commerce Gold certification for a procurement process or simultaneous large-scale parallel delivery

Right call if: a UK manufacturer, wholesaler, or distributor is on Orderwise and needs a Shopify wholesale portal with built-in credit control and trade pricing, or is evaluating a Magento B2B build with a packaged starting point rather than a blank-canvas custom project.

7. iWeb

UK Adobe Commerce Gold Partner with 24+ years of B2B and B2C platform delivery across complex ERP integrations, digital marketing, and multi-territory commerce

Why they’re on this list: iWeb is one of the longest-tenured Adobe Commerce agencies in the UK market, referenced by Adobe’s own Partner Sales team as the agency for enterprise-level merchants with complex ERP integrations, with documented B2B client work for JCB and MJ Baker Foodservice.

Strength: Adobe Commerce Gold Partner depth with genuine B2B integration capability: Salesforce CRM-to-Adobe-Commerce-to-ERP integration, Akeneo PIM (Gold Partner), headless and PWA development, and multi-territory commerce across B2C, B2B, and B2C2B from a single platform
Platform competencies: Adobe Commerce/Magento (primary), Hyvä, headless/PWA; PIM via Akeneo Gold Partner; digital marketing, SEO, and content alongside platform work
Marketing scope: Digital strategy, SEO, content marketing, social media, paid advertising, and CRO integrated with platform delivery
Caveat: Primary positioning is around Adobe Commerce; brands on Shopify, BigCommerce, or platforms outside the Adobe ecosystem will find iWeb’s deepest capability doesn’t apply to their stack

Right call if: a UK or international B2B ecommerce brand is on Adobe Commerce, has complex ERP and data integration requirements, and wants a single agency covering the platform and the digital marketing rather than coordinating two.

8. Shero Commerce

Shopify Premier Partner for complex B2B and DTC builds, with ERP integration scoped in discovery and 99% post-launch client retention.

Why they’re on this list: Shero holds Shopify Premier Partner status (one of fewer than 150 agencies globally), has built B2B Shopify architecture for manufacturers including Benchmade Knife Company (3+ year engagement, growth in B2B ecommerce and search performance) and Painful Pleasures (complex B2B features, bulk ordering, and intricate pricing logic on a 40,000+ SKU catalog), and reports 99% of clients continue on retainer after project close.

Strength: They tackle backend data links during discovery rather than treating them as a post-launch afterthought. All data flows for systems like NetSuite, SAP, Dynamics, and Epicor are fully mapped out before development starts. This meticulous preparation allows them to build complex B2B capabilities, like custom tier pricing, net terms, and multi-user corporate accounts, side by side with DTC channels on a single platform.
Platform competencies: Shopify Plus (Premier Partner, primary), Adobe Commerce/Magento (certified, supported), BigCommerce; full-funnel marketing including SEO, paid media, email, and CRO post-launch
Marketing scope: SEO, paid media, email marketing, and CRO managed as a single integrated program, not separate channel retainers
The Catch: Their client retention and delivery track record remain incredibly high, but for highly complex builds, it is smart practice to request a clear breakdown of their active technical bandwidth for your account before signing.

Right call if: You need to run wholesale and retail from the same Shopify Plus platform, want your ERP connection mapped out accurately before development starts, and want a partner that stays around to support you long after launch.

9. Scandiweb

A veteran enterprise commerce firm handling $4B in annual GMV through deep Adobe technical mastery and custom B2B workflow engineering.

Why they’re on this list: Scandiweb holds the #1 most-certified position on both Adobe Commerce and Hyvä globally, has delivered 2,100+ ecommerce projects for clients including PUMA, Ford, Jaguar, Land Rover, Toyota, and the Boy Scouts of America, and runs a full growth marketing practice (enterprise SEO, PPC, email, CRO, AEO, analytics) alongside its development teams.

Strength: They run enterprise development and full growth marketing under one roof. This eliminates the friction typical of large builds, allowing them to construct complex, multi-channel wholesale architectures that align perfectly with their customer acquisition strategies.
Platform competencies: Adobe Commerce (Gold Partner, #1 most certified globally), Hyvä (Platinum Partner, #1 most certified globally), Shopify, BigCommerce, Salesforce Commerce Cloud, SAP Commerce Cloud; headless and PWA capabilities
Marketing scope: Enterprise SEO, PPC, email, AEO (AI search), CRO, data analytics, website localization, and lifecycle marketing as a dedicated growth marketing practice
The Catch: Expect enterprise-level fees. They are built to support major international players, so if your business is under the $5M threshold, their minimum project rates will likely outweigh your operational scale.

Right call if: a B2B or omnichannel brand at $50M+ in revenue needs one partner across platform engineering and full growth marketing, with the certification depth and agency scale to handle enterprise complexity without coordinating separate development and marketing vendors.

10. Novatize

North American unified commerce and B2B ecommerce agency, with a proprietary Shopify B2B accelerator for manufacturers and distributors.

Why they’re on this list: Quebec City-based Novatize won the B2B Agency of the Year (Small/Medium System Integrator category) at the 2025 B2B eCommerce World Awards in Scottsdale and launched SPINE, a proprietary Shopify B2B accelerator, in September 2025, built specifically to reduce implementation time for manufacturers and distributors on Shopify’s B2B infrastructure.

Strength: The SPINE accelerator is specific and verifiable: a turnkey Shopify implementation framework built for complex B2B environments (company accounts, tiered pricing, custom catalogs, order minimums, ERP integration) that shortcuts the timeline manufacturers typically face building this from scratch. Named clients include Via Rail, Simons, Canadian Red Cross, Garant, and Exceldor
Platform competencies: Shopify (SPINE accelerator), Adobe Commerce/Magento, BigCommerce, with ERP, CRM, OMS, and PIM integration; unified commerce across online, physical, and B2B portal channels
Marketing scope: B2B marketing, customer acquisition, SEO, CRO, email and SMS, data analytics, CLV strategy, and agentic commerce
The Catch: They are optimized for mid-sized North American rollouts. If your organization operates across multiple continents or needs a massive army of developers working simultaneously, a global systems integrator will fit your scale better.

Right call if: You’re a North American manufacturer or distributor who wants one award-winning team to own both the Shopify B2B rollout and the long-term marketing strategy.

What to Look for in a Leading B2B Ecommerce Agency

The agencies on this list cover a wide range of models, from boutique mid-market specialists to enterprise-scale full-service groups. What they share is a common starting point: they understand the B2B buyer before they start on the build or the campaign.

Finding the right partner among the leading B2B ecommerce agencies comes down to matching agency type to the actual constraint. Three questions cut through most of the noise: Does the agency have verifiable case studies for brands at your revenue scale and in your operational context? Do they scope integrations in discovery, or design them during build? And who actually works on your account after the sales process ends?

The answers determine whether the engagement produces a functioning B2B commerce program or a well-presented project that doesn’t survive first contact with your ERP.
