Choosing a B2B Ecommerce Agency: 10 Partners for Complex Growth

Most B2B ecommerce projects are sold as website projects.

That is the first mistake.

A distributor’s ecommerce portal is not simply a product catalog with a checkout button. It is a digital representation of customer agreements, inventory commitments, payment terms, account permissions, sales territories, shipping rules, and procurement processes.

When those commercial rules are translated badly, the damage is immediate. A customer sees the wrong price. An unavailable product appears ready to ship. A purchasing manager cannot route an order for approval. A long-standing account is asked to pay by credit card even though it has negotiated net terms.
At that point, a more attractive homepage will not solve the problem.

Choosing the right B2B ecommerce agency begins with understanding where the buying system is breaking. Some agencies are built to repair ERP connections. Others specialize in Shopify, BigCommerce, Adobe Commerce, product data, customer acquisition, or enterprise-scale transformation. A smaller group can coordinate the transaction platform and the marketing program under one strategy.

This guide compares ten agencies with different areas of strength. It is not a universal ranking. Instead, it is designed to help manufacturers, wholesalers, distributors, and hybrid B2B brands identify the type of partner that fits their most urgent constraint.

Chapters

What Should a B2B Ecommerce Agency Be Able to Solve?

A qualified agency should be able to work across at least one of five operational layers.

1. Commercial rules

This includes customer-specific pricing, volume discounts, credit limits, tax exemptions, payment terms, quotes, purchase orders, account roles, and internal approval paths.

2. Business data

Product information, inventory, pricing, customer records, order history, invoices, and fulfillment status must move accurately between the storefront and systems such as an ERP, CRM, PIM, or order management platform.

3. Buyer workflow

Business buyers need to find products quickly, order by SKU, upload order lists, request quotes, repeat previous purchases, check invoices, and manage several users under one company account.

4. Customer acquisition

The company must attract the right purchasing teams through search, paid media, email, account-based marketing, content, and other channels without evaluating every visitor as though they have equal commercial value.

5. Digital adoption

Launching a portal is not the same as getting customers to use it. Sales representatives, customer service teams, and buyers need a reason to move away from phone calls, spreadsheets, emails, and legacy ordering processes.

Few agencies are equally strong across all five layers. That is why the initial diagnosis matters more than the size of the agency’s pitch deck.

How the Agencies Were Evaluated

The agencies in this guide were selected using the following criteria:

• A current, publicly documented B2B commerce capability
• Experience relevant to manufacturers, wholesalers, distributors, or complex business sellers
• A distinguishable strength in marketing, integration, platform development, product data, strategy, or buyer experience
• Evidence of support for business purchasing workflows rather than standard consumer checkout alone
• Enough specialization to explain when the agency should, and should not, be shortlisted

The list is organized by business problem rather than by an arbitrary overall score. Publicly available capabilities were reviewed in July 2026. Companies should still verify all agency claims through technical discovery, client references, and conversations with the proposed delivery team.

B2B Ecommerce Agencies at a Glance

1. SeedX

Best for connecting customer acquisition with account-level revenue

Many B2B ecommerce companies have plenty of marketing activity but very little commercial clarity.

Paid campaigns report conversions. The CRM reports opportunities. The ecommerce platform reports orders. The finance team reports revenue and margin. Unfortunately, these systems often disagree about which activities created the customer and whether that customer is actually profitable.

SeedX is a B2B ecommerce agency built for companies that need to connect acquisition activity with customer behavior, account value, reordering, and revenue reporting.

Its published capabilities include SEO, lifecycle email, account-based marketing, HubSpot, Salesforce, CRM integration, data warehousing, performance reporting, and strategies for improving visibility across AI-assisted search experiences. SeedX positions its work at the system level, connecting marketing with ecommerce, operations, fulfillment, and customer data rather than evaluating each channel in isolation.

This approach is particularly useful when the storefront already functions but management cannot confidently answer questions such as:

• Which campaigns are creating high-value business accounts?
• Which customer segments are reordering?
• How much does it cost to acquire an account rather than a lead?
• Which products and customers contribute healthy margins?
• Where are prospects disappearing between marketing and sales?

Best fit: A B2B seller with active acquisition channels, CRM data, and online orders but no unified view of performance.

Important limitation to investigate: A growth and data partner should not automatically be treated as a replacement for a specialized ERP engineering company. If the primary problem is highly customized pricing or inventory logic, ask for technically comparable integration examples before defining the scope.

2. Smith

Best for large companies that need commerce, marketing, and data under one program

Smith describes itself as a performance commerce agency. Its capabilities span customer experience, commerce technology, digital marketing, and data and AI, with dedicated work in manufacturing and distribution.

The agency also lists partnerships involving SAP, commercetools, and Kibo. That breadth makes it a relevant option when a company does not want platform development, customer experience, marketing, and analytics managed by unrelated vendors.

Smith’s model is most useful when ecommerce is already a meaningful revenue channel or is expected to become one. A manufacturer may need to modernize the transaction platform, improve product discovery, increase portal adoption, optimize media, and introduce better reporting at the same time.
The advantage is coordination. The risk is scope complexity.

Best fit: An established manufacturer or distributor seeking a broad transformation partner rather than a narrow implementation shop.

Important limitation to investigate: Ask which team will own the architecture, which team will own acquisition, and how the two groups will make decisions together. A broad agency relationship only creates value when responsibilities remain clear.

3. Americaneagle.com

Best for industrial companies with complicated operational systems

Americaneagle.com combines custom development and digital marketing for manufacturers and distributors.

Its published industrial practice covers ERP, PIM, supply-chain, and ecommerce integration. The company also describes support for negotiated pricing, customer-specific catalogs, purchase orders, approval workflows, PunchOut, multi-location inventory, buyer portals, order history, warranty information, quoting, and digital marketing. It identifies experience with systems such as Prophet 21, Epicor, Infor, NetSuite, SAP, and proprietary business software.

This breadth makes Americaneagle.com relevant for companies whose ecommerce project crosses several internal departments. The marketing team may need better lead generation while operations needs accurate inventory, IT needs manageable integrations, and customer service needs a self-service portal that reduces routine requests.

Best fit: A manufacturer or distributor that needs custom development, industrial system integration, and ongoing marketing support from one large provider.

Important limitation to investigate: “ERP experience” is too broad to be meaningful on its own. Ask for a reference involving the exact ERP version, ecommerce platform, pricing model, catalog size, and order workflow used by your organization.

4. Xngage

Best for manufacturers and distributors seeking a focused B2B specialist

Xngage concentrates on ecommerce for manufacturers, distributors, and wholesalers. Its services include B2B strategy, platform implementation, user experience, PIM implementation, process improvement, and digital growth.

The company is based in Cleveland and presents a portfolio centered on established distribution and industrial organizations rather than primarily consumer retail brands.

That industry focus can reduce the amount of time spent explaining why business buyers need capabilities such as product lists, branch inventory, account pricing, technical search, and repeat ordering.

It can also help when internal teams need a partner that understands ecommerce as an operating channel, not just a web property.

Best fit: North American manufacturers, wholesalers, and distributors that want a partner familiar with established B2B processes and digital transformation.

Important limitation to investigate: Confirm the agency’s practical experience with your selected platform, ERP, search technology, and PIM. Industry familiarity is valuable, but the proposed technical team must still match the actual stack.

5. Rixxo

Best for companies that have not yet chosen the right platform

A surprising number of ecommerce projects begin with a platform decision that has already been made.

The company selects software after a demonstration, hires an agency to implement it, and only later discovers that the platform cannot support a critical pricing rule or purchasing workflow without expensive customization.

Rixxo takes a more advisory-led position. Its current services cover business assessment, platform selection, platform validation, strategy, integrations, automation, implementation, training, adoption, optimization, and internal team development. The agency’s focus includes manufacturers, wholesalers, distributors, building-material businesses, and automotive-parts companies.

Rixxo is therefore worth considering before issuing a platform-specific request for proposal. Its greatest value may be helping a company determine whether it needs a replatform at all.

Best fit: A B2B company that understands its commercial goals but remains uncertain about platform selection, internal readiness, or the right sequence of investment.

Important limitation to investigate: Clarify which implementation work Rixxo will deliver directly, which work may involve technology partners, and who remains accountable after the strategy phase.

6. Charle Agency

Best for Shopify Plus wholesale and hybrid B2B-DTC businesses

Charle Agency is a Shopify specialist with a dedicated B2B and wholesale practice.

Its published services cover Shopify and Shopify Plus implementations for brands selling to both consumers and business accounts. The agency works with Shopify’s native B2B capabilities, custom Shopify architecture, wholesale applications, and tools such as SparkLayer.

This makes Charle particularly relevant to a brand that has already committed to Shopify and wants to operate retail and wholesale commerce within a coordinated environment.

The agency should be able to help determine whether the company needs a blended storefront, a separate B2B experience, or additional applications layered onto Shopify’s native features.

Best fit: A wholesale or hybrid brand that has selected Shopify Plus and needs implementation, design, customization, and post-launch growth support.

Important limitation to investigate: Do not assume every B2B requirement can be handled through a standard app. Ask the agency to demonstrate how it would support your account hierarchy, contract pricing, payment terms, tax rules, ERP, quoting process, and product data.

7. i95Dev

Best for repairing ecommerce and ERP communication

When the storefront shows the wrong information, the problem may not be the storefront.

It may be an integration that updates inventory too slowly, fails to recognize an account’s price list, drops an order field, or cannot reconcile offline and online purchasing history.

i95Dev specializes in connecting ecommerce and ERP systems. Its current offering supports platforms including Adobe Commerce, Shopify, and BigCommerce, alongside ERP environments such as Microsoft Dynamics, SAP Business One, and NetSuite. It also publishes support for custom fields, customer pricing, complex B2B workflows, portals, marketplaces, and wider CRM and PIM connectivity.

This integration-first approach is useful when the company wants to preserve its existing storefront while fixing the flow of pricing, inventory, customer, and order data.

Best fit: A manufacturer, distributor, or hybrid seller whose customer experience is being undermined by disconnected back-office systems.

Important limitation to investigate: Integration expertise does not necessarily include brand strategy, demand generation, or extensive front-end experience design. Establish whether those areas require a second partner.

8. Web Solutions NYC

Best for complex Adobe Commerce and Magento implementations

Adobe Commerce remains a common choice for B2B businesses that need extensive customization and detailed account workflows.

Web Solutions NYC focuses on Adobe Commerce and Magento development for enterprise and B2B environments. Its published capabilities reference company accounts, account hierarchies, approval workflows, customer-specific pricing, negotiated quotes, requisition lists, purchase-order payments, and net terms. It also identifies experience across manufacturing, wholesale distribution, industrial equipment, and related complex sectors.

This makes the agency relevant when standard SaaS functionality cannot comfortably support the company’s pricing rules, buyer structures, or transactional requirements.

Best fit: A business already running Adobe Commerce or selecting it because its B2B model requires substantial customization.

Important limitation to investigate: Adobe Commerce provides flexibility, but that flexibility brings operational responsibility. Confirm hosting, upgrades, security, extension management, quality assurance, monitoring, and long-term maintenance before approving the architecture.

9. 5874 Commerce

Best for BigCommerce, Shopify Plus, product data, and connected architecture

5874 Commerce works across B2B, direct-to-consumer, and headless commerce, with capabilities in platform strategy, integration, product data, user experience, conversion optimization, and ongoing support.

The agency identifies platform expertise across BigCommerce and Shopify Plus and describes connecting commerce with ERP and PIM environments. Its B2B services include portals, complex procurement, custom pricing, system architecture, and continuous optimization.

This combination is useful when the business needs more than a front-end implementation. Large catalogs often require better product information management, while business workflows require reliable middleware and integration architecture.

Best fit: A B2B seller evaluating BigCommerce, Shopify Plus, headless commerce, PIM, or an interconnected technology stack.

Important limitation to investigate: The agency covers several disciplines. Confirm which specialists are included in the proposed account team and whether marketing, product data, integration, and development are all part of the contracted scope.

10. Fluid Commerce

Best for combining B2B platform work with ecommerce marketing

Fluid Commerce supports B2B customer portals and ecommerce websites on Adobe Commerce, Magento Open Source, Shopify, and Hyvä.

Its service offering covers ERP integrations, self-service account functionality, platform development, support, PPC, paid social, and SEO for manufacturers, wholesalers, distributors, and suppliers. Fluid also offers a Magento-based B2B portal product for companies seeking common wholesale features without moving to a larger Adobe Commerce implementation.

This creates a practical middle ground for companies that need technical implementation and post-launch customer acquisition but do not want to coordinate a development agency and a separate performance-marketing firm.

Best fit: A mid-market B2B seller that needs Adobe Commerce, Magento, or Shopify expertise alongside ongoing search and paid-media support.

Important limitation to investigate: Organizations managing many countries, business units, languages, and enterprise systems should confirm that the proposed team has the capacity and governance experience required for the full program.

Match the Partner to the Problem

The most expensive agency mistake is choosing a partner for the project you think you need instead of the problem you actually have.

Your storefront works, but acquisition performance is unclear

Begin with SeedX. The priority is not a replatform. It is connecting customer acquisition, CRM activity, online orders, retention, and financial performance.

You need a broad enterprise transformation

Evaluate Smith or Americaneagle.com. Both are better suited to programs that span technology, customer experience, operations, and growth.

You want an industry-focused partner for manufacturing or distribution

Xngage belongs on the shortlist, particularly when the company values a team centered on industrial and distribution use cases.

You are uncertain which platform to buy

Start with Rixxo before issuing a platform-specific request for proposal. A neutral assessment can prevent years of customization around the wrong software.

Shopify Plus has already been selected

Charle Agency is the most platform-focused candidate in this list for Shopify B2B and wholesale implementations.

Pricing, inventory, and account data do not synchronize

Talk to i95Dev before replacing the entire storefront. The primary requirement may be integration rather than redesign.

Adobe Commerce or Magento is central to the roadmap

Web Solutions NYC and Fluid Commerce are the most relevant options in this list. The better choice depends on whether the priority is deep platform engineering or a combination of development and marketing.

BigCommerce, Shopify Plus, PIM, or headless architecture is under consideration

5874 Commerce may be a useful fit when platform implementation, product data, integrations, and ongoing optimization must work together.

Warning Signs in an Agency Proposal

A professional proposal should make a complicated project easier to understand. Be careful when it does the opposite.

The agency cannot identify the system of record

It should be clear whether the ERP, ecommerce platform, CRM, or another system controls pricing, inventory, customer status, product content, and order information.

The integration is described only as “seamless”

A credible scope explains which data objects move, in which direction, how frequently, through which technology, and what happens when a connection fails.

Success is defined entirely by traffic or ROAS

Channel metrics can help optimize campaigns, but they do not reveal whether marketing is creating valuable accounts, repeat orders, healthy margins, or qualified pipeline.

The agency recommends a replatform before completing discovery

A replatform may be necessary, but it should follow a documented assessment of the existing platform, integrations, data, workflows, and cost of ownership.

The customer-adoption plan is missing

A portal will not create value when buyers continue placing every order through email and sales representatives quietly discourage digital adoption.

The people presenting the proposal will not deliver the work

Meet the solution architect, project lead, integration lead, and marketing strategist who will be responsible after the contract is signed.

Questions to Ask Every Agency

Use the following questions during the final selection process:

• Which system will control customer pricing, inventory, credit limits, product content, and order status?
• Which information will move in real time, and which information will synchronize on a schedule?
• How will the platform support company accounts, user roles, spending limits, and approvals?
• Can buyers see orders placed through sales representatives or other offline channels?
• How will quotes, purchase orders, net terms, invoices, and tax exemptions be managed?
• What is the process for cleaning and migrating customer, product, and order data?
• How will the agency test pricing, inventory, permissions, and integrations before launch?
• What happens when the ERP or another critical service is unavailable?
• How will customers and sales teams be encouraged to adopt the new channel?
• How will acquisition costs be connected to account value, repeat orders, margin, and revenue?
• Who will monitor integrations and platform performance after launch?
• Which assumptions could materially change the budget or schedule?

Strong agencies will answer with diagrams, examples, responsibilities, and documented assumptions. Weak agencies will return to general language about innovation and seamless experiences.

Choosing by Service, Platform, and Location

A company searching for a b2b ecommerce marketing agency usually has a different problem from one seeking an integration specialist. The platform may already work, but the business needs qualified traffic, stronger account acquisition, improved attribution, and more repeat purchasing. The agency should report on account quality and commercial outcomes rather than stopping at form submissions.

A b2b ecommerce digital marketing agency should understand that the person clicking an advertisement may not be the final decision-maker. Campaign strategy should account for technical evaluators, procurement teams, finance stakeholders, sales representatives, and the length of the buying process. Content, SEO, paid media, email, CRM, and analytics must support the same account journey.

Location-based searches can be useful, but they should not control the decision. A search for a b2b ecommerce agency in boston, a b2b ecommerce agency cleveland, or a b2b ecommerce agency austin can help identify teams available for local workshops. The next step should still be evaluating platform experience, ERP familiarity, catalog complexity, buyer workflows, and the quality of the proposed delivery team. Xngage, for example, is based in Cleveland and specializes in manufacturers, distributors, and wholesalers, but a buyer should still verify technical fit.

A shopify b2b ecommerce agency should demonstrate more than theme development. Ask to see company accounts, customer-specific catalogs, wholesale pricing, payment terms, buyer permissions, blended B2B-DTC architecture, ERP integration, tax handling, and bulk-order workflows.

A bigcommerce b2b ecommerce agency should be able to show account hierarchies, price lists, quoting, invoice payments, reordering, approval rules, sales-representative involvement, ERP connectivity, and practical experience with BigCommerce B2B Edition. Partner status is useful, but a comparable implementation is stronger evidence.

Final Thoughts

The best B2B ecommerce partner is not necessarily the agency with the largest development team, the most platform badges, or the most impressive design portfolio.

It is the agency that accurately identifies the constraint standing between your customers and a completed order.

For one company, that constraint is a broken ERP integration. For another, it is poor product data. For another, the technology works but marketing cannot distinguish valuable accounts from low-quality traffic. Some companies need a large transformation partner. Others need a narrow specialist to repair one critical layer without rebuilding everything around it.

Begin with the failure point.

Then choose the agency whose people, process, and technical experience are built around solving it.

FAQs About B2B Ecommerce Agencies

What is a B2B ecommerce agency?

A B2B ecommerce agency helps companies build, connect, market, and optimize digital purchasing channels used by other businesses. Its services may include ecommerce strategy, platform development, ERP and CRM integration, account-specific pricing, buyer portals, SEO, paid media, analytics, and customer adoption.

How is a b2b ecommerce marketing agency different from a development agency?

A b2b ecommerce marketing agency focuses on attracting qualified business accounts, improving attribution, increasing customer value, and encouraging repeat purchases. A development agency focuses primarily on platform functionality, performance, integrations, security, and technical maintenance. Some agencies provide both services, but their depth should be evaluated separately.

When should a company hire a b2b ecommerce digital marketing agency?

A company should hire a b2b ecommerce digital marketing agency when the platform is stable but the business lacks qualified demand, accurate attribution, account-level reporting, or a reliable retention program. Marketing investment should not be increased while buyers are still encountering inaccurate pricing, unavailable inventory, or broken purchasing workflows.

Is hiring a b2b ecommerce agency in boston better for a Boston company?

Hiring a b2b ecommerce agency in boston can make in-person workshops easier, but location does not prove relevant expertise. A Boston business should first evaluate industry experience, platform knowledge, ERP capability, delivery-team quality, and comparable client work.

What should I check when comparing a b2b ecommerce agency cleveland result?

When reviewing a b2b ecommerce agency cleveland result, confirm that the firm has genuine B2B commerce experience rather than general web-development capability. Ask for manufacturer or distributor references, platform credentials, integration examples, and evidence involving contract pricing, product data, buyer accounts, and repeat ordering.

How should I evaluate a b2b ecommerce agency austin search result?

A search for a b2b ecommerce agency austin may return development firms, consumer ecommerce agencies, consultants, and marketing companies. Classify each company by its real specialty before arranging calls. Determine whether your primary requirement is platform development, ERP integration, product data, digital marketing, or a coordinated combination.

What should a shopify b2b ecommerce agency provide?

A shopify b2b ecommerce agency should support Shopify Plus company accounts, catalogs, price lists, payment terms, user permissions, wholesale checkout, and B2B-DTC architecture. It should also be able to explain how Shopify will connect with the ERP, PIM, CRM, tax, inventory, and fulfillment systems.

What should a bigcommerce b2b ecommerce agency provide?

A bigcommerce b2b ecommerce agency should understand BigCommerce B2B Edition, account roles, customer pricing, quotes, purchase orders, invoices, approval processes, quick ordering, reordering, and backend integrations. Request a demonstration or case study involving a business with similar catalog and workflow complexity.

Should an agency manage both development and marketing?

One agency can manage both when its technical and marketing practices are sufficiently developed and operate under a shared measurement model. This arrangement reduces vendor coordination, but the company should meet the leaders of both teams and understand how platform priorities will be balanced against acquisition goals.

How much does a B2B ecommerce agency cost?

Cost depends on the platform, ERP, catalog size, data quality, custom workflows, number of markets, integrations, migration requirements, and support model. A buyer should request a phased estimate showing assumptions, exclusions, dependencies, third-party fees, and change-control rules rather than relying on one unexplained project total.
