Top B2B Ecommerce Agencies

Picking the right B2B ecommerce agency is more challenging than it initially appears because while many agencies claim to serve B2B clients, only a few truly understand how B2B ecommerce works commercially, including longer sales cycles, complex procurement processes, and the direct connection between marketing efforts and high-value contract revenue, where a buyer placing a large order expects a seamless and highly functional purchasing experience rather than a basic consumer-style checkout; the best B2B ecommerce agency partners focus first on the buyer journey and workflow before allocating ad spend, understand critical metrics like TACoS, CAC, and contribution margin at an account level rather than just by channel, and recognize that most B2B marketing challenges stem from data and systems rather than creative execution, which is why there is no single “best” agency but instead a range of specialized partners, from enterprise-level firms handling complex digital transformations for manufacturers to agile mid-market teams offering end-to-end ecommerce and marketing solutions, as well as niche experts focused on specific platforms, making it essential to choose a B2B ecommerce agency that aligns with your operational needs, technology stack, and growth goals to ensure measurable and scalable results.

Top B2B Ecommerce Agencies

1. SeedX

SeedX is a performance-focused B2B ecommerce agency specializing in full-funnel growth by connecting paid acquisition, customer data, and margin reporting into one unified system, ensuring every marketing effort is tied directly to real business outcomes; while most B2B ecommerce brands can report revenue, very few have clear visibility into their true customer acquisition cost (CAC) at the account level or understand which channels are driving profitable growth versus wasting budget, because traditional marketing dashboards operate in silos, but SeedX eliminates this gap by integrating customer acquisition, CRM pipelines, and sales data directly with financial reporting, allowing businesses to track campaign performance against contribution margin, identify high-value channels, and make data-driven decisions that scale revenue efficiently; as a results-driven B2B ecommerce agency, SeedX enables leadership teams to gain real-time insights into profitability, ensuring marketing spend is aligned with long-term growth and sustainable ROI.

Supported Tech Stack: Shopify, HubSpot, Salesforce, and Klaviyo.

• Paid media tied to contribution margin, not ROAS

• Cross-channel attribution and CRM integration

• Lifecycle and retention strategy for B2B account growth

Strongest when: Acquisition and retention are siloed, CAC at the account level is unclear, or marketing spend isn't connected to margin outcomes.

2. Zaelab

Enterprise B2B commerce and CPQ specialist for manufacturers and distributors with complex self-service and digital revenue transformation requirements

Zaelab works exclusively in enterprise B2B, which means they've never had to adapt a consumer commerce model to fit a manufacturer. Simpson Strong-Tie earned Enterprise B2B Ecommerce Manufacturer of the Year after Zaelab built their experience: now over 60% of sales flow through digital channels. ESAB went to market on a new commerce platform in 120 days. Gesswein saw a 101% increase in transactions and 343% growth in site visitors post-launch. Named clients also include ABB, Titleist, Milwaukee Tools, and GE. 

Their strength is CPQ and guided selling through Logik.ai, which is the kind of capability that B2B brands with configurable products usually can't get from generalist agencies. 

Note: their pricing and engagement model is built for enterprise scale. Mid-market brands with smaller programs should verify fit early.

Strongest when: a manufacturer or distributor needs CPQ, self-service portals, or digital revenue transformation at enterprise scale, and the organizational complexity matches the agency's delivery model.

3. Wagento

ERP-first B2B ecommerce agency for manufacturers and distributors, with a dedicated GrowthX marketing practice covering SEO, AEO, PPC, CRO, and email measured against revenue

With 14 years and more than 400 builds under their belt, Wagento is designed for the hard technical realities of wholesale commerce. Their work for industrial wire distributor Lapp Tannehill is a prime example: they linked Adobe Commerce directly to an Epicor Prelude ERP, serving up real-time contract pricing and live stock levels on every single SKU. Once live, their GrowthX team takes over, driving customer acquisition through enterprise SEO, AI-search visibility, and paid campaigns, all tracked against actual sales rather than isolated marketing reports.

Core Systems: Adobe Commerce integrated with Epicor Prelude ERP.

Note: Wagento is a B2B manufacturing specialist. If your business isn't in manufacturing or distribution, this likely isn't where you'll find the deepest fit.

Strongest when: When you want one partner to own software engineering and marketing under one roof. They build your transaction engine, map your ERP data, and launch your growth marketing without a single external handoff.

4. Bounteous

An enterprise digital commerce and marketing agency specializing in B2B platforms for manufacturing and industrial brands.

Bounteous has spent more than two decades scaling into a global digital transformation leader. They are the agency enterprise manufacturers turn to when they want to consolidate legacy storefronts without losing the human touch of buyer personalization. 

Backed by their late-2025 Forrester recognition and a Vendor of the Year title from Texas Roadhouse, they excel at building highly sophisticated B2B2C environments where loyalty and transactional accuracy must function under a single digital roof. 

Right call if: You need an enterprise-grade integrator to build a highly personalized B2B commerce ecosystem, with the global bandwidth to manage both deep backend data structures and front-end buyer retention.

5. Above The Fray

End-to-end B2B ecommerce agency for manufacturers and distributors, certified across Adobe Commerce, BigCommerce, Shopify, and Shopware, with integrated marketing and dealer portal capability

Above The Fray serves industrial brands that need real technical depth and marketing execution from the same team. They handle the difficult backend integrations, custom portal builds, and product configurators that generalist agencies avoid. They also bundle your SEO, paid ads, and lifecycle marketing into your main contract, meaning no extra agencies to manage after launch.

This is your partner if you need a highly technical B2B shop that can write clean code for your backend systems and immediately pivot to driving traffic to your new store.

6. Nishtech

Digital experience, ecommerce, and marketing strategy agency for B2B brands on Optimizely, Shopify Enterprise, and Salesforce B2B Commerce

You can't hide a lack of technical depth when building on a platform like Optimizely B2B. Nishtech is one of the few agencies with the actual coding history to back up its claims. They also deploy high-performing stores on Shopify Enterprise and Salesforce, focusing heavily on how digital operations feed into your marketing. They treat your site's user experience as your most important sales tool.

Right call if: You need to build a complex B2B store on Optimizely, Shopify, or Salesforce, and you want your technical architecture to naturally support your sales goals.

7. Ziffity

Enterprise ecommerce and digital marketing agency for distribution, manufacturing, and CPG brands, with cross-platform delivery across Adobe Commerce, BigCommerce, Shopify Plus, and Salesforce Commerce Cloud

If your business relies on a mixed bag of platforms like BigCommerce, Marketo, and Adobe Analytics, finding a single partner who actually understands how they all talk to each other is rare. Ziffity specializes in these complex, multi-tool environments, managing the technical development and running your marketing campaigns side by side. The only real caveat here is their sheer breadth, so you should verify they have deep, practical coding experience with your specific software.

Best fit if: You have a mixed tech stack and need an unbiased partner to handle both the technical build and your growth marketing.

8. Apply Digital

Customer experience, commerce, and data agency for enterprise CPG and B2B brands running large product and brand portfolios

Apply Digital works at the intersection of commerce, content, data, and personalization, which makes them a stronger fit for the type of B2B and CPG enterprise brand where the complexity isn't just the platform but the scale of the product catalog, the number of brand entities, and the need for personalization that actually changes what each buyer sees. Their delivery spans Salesforce, Adobe, and composable commerce architectures, and they have documented experience building scalable digital experiences for large organizations that are trying to move fast without breaking their existing systems. 

They're not a B2B-exclusive agency, which is worth noting; their strength is in the intersection of data, content, and commerce at enterprise scale.

Strongest when: Large B2B or CPG enterprises need commerce, content, and personalization working from the same data foundation, and the program is complex enough that a narrowly scoped implementation agency won't cover the full requirement.

9. Swanky

Shopify Plus ecommerce growth and retention agency for B2B and hybrid commerce brands, with CRO, paid media, SEO, email, and loyalty running alongside platform delivery

Most Shopify agencies are built for retail brands and try to stretch standard templates for trade buyers. Swanky is different. They have a real wholesale practice that understands B2B realities like custom price lists, complex company accounts, and net terms. Once your portal is built, they deploy their in-house growth marketing team to run your SEO, email, and ad spend. The obvious catch is that they only work on Shopify. If your tech roadmap requires a different architecture down the line, they are not your partner.

Go with them if: You have already committed to Shopify Plus for a B2B or hybrid setup and want a single team to build the store and run the marketing.

10. Publicis Sapient

Global enterprise digital commerce and customer engagement agency for complex B2B and CPG ecommerce programs needing commerce strategy, personalization, and marketplace alignment at scale

Publicis Sapient is a massive global consultancy built for enterprise CPG and B2B manufacturers who need to launch across multiple countries, languages, and platforms simultaneously. They have the scale to easily handle complex setups involving SAP, Adobe, Salesforce, and composable architectures. The trade-off is the massive price tag and heavy corporate overhead. Their administrative processes and high-tier rates make them a poor choice for any brand operating below the Fortune 500 level. 

Choose them if: You’re a multi-market enterprise that needs a global partner capable of managing complex, cross-functional programs that would break a smaller agency.

What the Top B2B Ecommerce Marketing Agencies Actually Do Differently

The agencies worth hiring on this list share a quality that's harder to find than it should be: they think about revenue before they think about reach.

Top B2B ecommerce marketing agencies don't lead with impressions, traffic, or ROAS in isolation. They ask who the buyer is, how the account value compounds over time, what the CAC looks like relative to contract value, and whether the data infrastructure will actually tell you any of that. Those questions shape the work before a campaign launches or a platform gets built.

Before shortlisting anyone, be honest about where your constraint actually lives. If the problem is that buyers can't self-serve through a complex catalog, the primary fix is the platform and the UX, not the ad spend. If the platform works but no one knows about it, or the marketing isn't connecting spend to pipeline, that's a marketing systems problem.

 The agencies that solve one of those well don't always solve both. The ones that solve both are worth paying more for.
