Search “best B2B ecommerce agency” and you will find lists that rank PPC firms next to platform implementers, count software products as agencies, and never once mention an ERP by name. If you run a manufacturing or distribution business, those lists are useless to you. Your project is not a website. It is a dealer network, a quoting process, a 40-year-old part numbering scheme, and an ERP that runs the plant, all of which have to keep working while the storefront goes live.
We are Web Solutions NYC, an ecommerce agency that has spent nearly two decades building for manufacturers, distributors, and wholesalers, and we are on this list. That is a bias, and we disclose it up front. What we offer in exchange is specificity: every agency below is named with verifiable credentials, the criteria are published, and we tell you which competitor to call when they are the better fit. We wrote more broadly about this market in our guide to B2B ecommerce for manufacturers; this post is the partner-selection companion to it.
The Best B2B eCommerce Agencies for Manufacturers and Distributors in 60 Seconds
The best B2B ecommerce agencies for manufacturers and distributors in 2026 are the ones built around the ERP, not the storefront: Web Solutions NYC (Adobe Commerce and Shopware, ERP-first builds for manufacturers and distributors), Corevist (managed B2B portals specifically for manufacturers on SAP), DCKAP (ERP-first integration for distributors), Atwix, Guidance, Classy Llama, IronPlane, Vaimo, and BORN Group for global enterprise. Judge candidates on five things B2B manufacturers and distributors uniquely need: dealer and distributor network support, configure-price-quote workflows, real-time ERP integration, long-tail SKU catalog performance, and MAP pricing enforcement. Expect $150,000 to $500,000+ for a serious implementation, with most of the budget in integration, and walk away from any agency that talks design before asking which ERP you run.
What manufacturers actually need from an ecommerce agency
Manufacturer ecommerce fails differently than retail ecommerce. The storefront is rarely the problem; the problem is everything behind it. Before we get to the list, here are the five requirements that should drive your shortlist, because most agencies have never built any of them.
Dealer and distributor network support
Most manufacturers do not sell only direct. You sell through dealers, reps, and distributors, and the channel politics are real. Your platform needs dealer-specific pricing and catalogs, territory logic, dealer locators, and sometimes a deliberate decision to route ecommerce leads to channel partners rather than around them. An agency that has only built direct-to-consumer stores will design channel conflict into your build without realizing it. (Distributors have their own version of this problem; we covered it in our guide to B2B ecommerce for distributors.)
Configure-price-quote (CPQ)
If your products are configured (sizes, materials, voltages, options that gate other options), a static product page does not sell them. You need guided configuration, validation rules that prevent impossible builds, and a quote workflow where complex carts become negotiable quotes routed to sales. CPQ is where “we support B2B” claims go to die; ask for a live example.
ERP-first operations
In manufacturing, the ERP is the system of record for everything: inventory across plants and warehouses, customer-specific contract pricing, credit limits, lead times, lot tracking. The storefront is a window into the ERP, not a parallel database. That means bidirectional, near-real-time integration with systems like SAP, NetSuite, Microsoft Dynamics, Acumatica, Sage, Epicor P21, or Infor, and it means the integration gets designed before the homepage does.
Long-tail SKU catalogs
Manufacturers and the distributors who carry them routinely run 50,000 to 500,000+ SKUs, most of which sell rarely but matter enormously when a plant is down waiting for a part. Catalog scale breaks naive builds: search, faceting, indexing, and price sync all need architecture decisions up front. A portfolio full of 200-SKU lifestyle brands tells you nothing about whether an agency can handle yours.
MAP pricing and channel governance
Minimum advertised price policies create requirements retail agencies have never met: hiding prices until login, “add to cart to see price” flows, different visibility rules per channel and per customer group, and enforcement reporting. Done wrong, MAP handling tanks both conversion and SEO. Done right, it protects your dealer relationships while you grow direct revenue.
How we built this list
We are on this list, so here is the method, stated plainly so you can audit it. To be included, a firm needed verifiable evidence of manufacturer or distributor work (named clients, named ERPs, published case studies), a real integration practice, and delivery coverage a US manufacturer can work with. We deliberately mixed two kinds of firms because manufacturers genuinely choose between them: full implementation agencies (us, Atwix, Guidance, Classy Llama, IronPlane, Vaimo, BORN) and productized specialists (Corevist for SAP manufacturers, DCKAP for distributor integration), and we say which is which. We excluded pure marketing agencies, platforms posing as agencies, and offshore shops; the pitfalls section explains why.
Use this table as your scorecard for anyone you evaluate, on this list or off it:
| Selection criterion | Why it matters for manufacturers | How to verify |
|---|---|---|
| Named ERP integration experience | The ERP runs the plant; the integration is the project | Ask for ERP names with project counts; “we use middleware” is a fail |
| Dealer/distributor channel work | Channel conflict can cost more than the build | Ask for a case study involving dealer pricing or portals |
| CPQ and quoting workflows | Configured products cannot sell through static pages | Ask to click through a live configurator or quote flow they built |
| Catalog scale (50k+ SKUs) | Search and indexing collapse on naive builds | Ask for their largest live catalog and its search response times |
| MAP pricing implementation | Pricing visibility rules are legal and channel commitments | Ask how they handle login-to-see-price without killing SEO |
| US-hours delivery team | Plant-floor and warehouse stakeholders cannot do 6 a.m. calls | Ask where the actual build team sits, not the account team |
1. Web Solutions NYC: ERP-first builds on Adobe Commerce and Shopware
We lead with ourselves, with the bias disclosed. Web Solutions NYC is a New York agency founded in 2007, with 50+ B2B implementations and a senior-only engineering team. Our manufacturer and distributor work runs through clients such as a calibration and test-equipment distributor, a medical-equipment distributor, and an industrial-supply distributor, and our integration bench covers NetSuite, SAP, Microsoft Dynamics, Acumatica, Sage, and Epicor P21 with bidirectional, real-time sync rather than nightly batch jobs. We build dealer portals, customer-specific pricing, quoting workflows, and catalogs past 500,000 SKUs.
We are official Adobe Commerce (Magento) partners and a Shopware Platinum Partner, the first Shopware agency in the US with more live US Shopware merchants than any other team, which lets us fit the platform to the catalog and licensing budget instead of forcing every project onto one stack. You can see how we think about this market on our B2B commerce industry page and our B2B services overview. Best for: mid-market and enterprise manufacturers, distributors, and wholesalers whose project is really an ERP integration project. Not for: startups, template builds, or anyone shopping primarily on price.
2. Corevist: managed portals for manufacturers running SAP
Corevist is not a traditional agency, and that is exactly why some manufacturers should call them first. They offer a managed B2B commerce platform built specifically for manufacturers on SAP ERP, with prebuilt, real-time SAP integration covering the full order-to-cash cycle, 49 SAP-certified integration points, and implementations they quote at 30 to 90 days. The platform reportedly processes over $2 billion in order value annually across manufacturing verticals from pharmaceuticals to industrial machinery.
The trade-off is flexibility: you are buying their platform and their roadmap, not a custom build. Best for: SAP-running manufacturers who want a customer ordering portal live in months, not a year. Not for: manufacturers on other ERPs, or anyone needing deep storefront customization.
3. DCKAP: ERP-first integration for distributors
DCKAP comes at the problem from the integration side. Their core product, DCKAP Integrator (formerly Cloras), is an iPaaS built for distributors that connects ERPs to ecommerce platforms, CRMs, PIMs, EDI, and marketplaces, automating order, inventory, pricing, and customer data flow. If your storefront is fine but your ERP and your channels do not talk to each other, this is the targeted fix.
Best for: distributors and the manufacturers who sell through them, especially when the pain is data flow rather than the storefront itself. Not for: ground-up storefront builds where you want one accountable design-and-build partner.
4. Atwix: elite Magento engineering with deep ERP credentials
Atwix is an Adobe Gold Solution Partner founded in 2006 and one of the top contributors to the Magento open source codebase. For manufacturers, the relevant proof is their integration record: 250+ ERP integrations claimed, a pre-integrated solution for Infor, and published case studies like Turf Care, an Adobe Commerce build with more than 120,000 SKUs and hardened Infor CSD integration, and a custom B2B portal for Byrne Electrical delivered on Adobe Commerce Cloud.
Best for: manufacturers committed to Adobe Commerce who need serious engineering depth on a large catalog. Not for: teams that want platform-agnostic selection help first.
5. Guidance: three decades of mid-market and enterprise commerce
Guidance has built commerce since 1993 from Los Angeles, with a stated focus on manufacturing and wholesale in the mid-market and enterprise. They are multi-platform (Adobe Commerce, BigCommerce, Shopify Plus, commercetools), and third-party rankings report client retention above 90%. For a manufacturer that has not yet picked a platform, a veteran multi-platform shop is a reasonable way to run selection and build with one partner.
Best for: mid-market and enterprise manufacturers that want platform selection and implementation under one roof. Not for: small builds; their floor is mid-market.
6. Classy Llama: integration-first commerce for the industrial Midwest
Classy Llama (Springfield, Missouri, founded 2007) is an Adobe Silver Partner with 125+ commerce sites and over 400 customizations and integrations behind it, focused explicitly on manufacturers, distributors, and complex retail, with vertical experience in agriculture, automotive, and outdoor industries. Their positioning leads with connecting ERP, PIM, CRM, payments, and tax to the storefront, which is the correct order of operations for manufacturer ecommerce.
Best for: manufacturers and distributors that want an integration-first Adobe Commerce partner with industrial vertical experience.
7. IronPlane: senior remote-US team with real B2B case studies
IronPlane is a Gold Adobe Solutions Partner headquartered in Portland, Maine, running a fully remote team of 50+ with a decade of B2B Magento work. Their case studies include Omni International, a manufacturer and distributor of laboratory equipment, which is precisely the unglamorous, high-SKU, regulated-adjacent work that predicts success on a manufacturer build.
Best for: manufacturers on Magento or Adobe Commerce that want senior US-based engineers without big-agency overhead.
8. Vaimo: enterprise B2B depth across regions
Vaimo (founded 2008, 650+ people in 15+ markets) is one of the most established Adobe Commerce partners globally, and their B2B practice covers exactly the manufacturer checklist: contract pricing, punchout integrations, approval workflows, and customer-specific inventory visibility for manufacturers, distributors, and wholesalers, plus managed services after launch.
Best for: manufacturers with multi-region storefronts and European or APAC operations alongside the US. Not for: single-region mid-market projects, where their scale works against you.
9. BORN Group: global enterprise transformations
BORN Group, a Tech Mahindra company and Magento Global Elite partner, operates at the top of the enterprise market with 500+ digital transformations delivered, its own Adobe Commerce accelerator (Bulldog), and parallel SAP Commerce and Salesforce practices. For a global manufacturer consolidating commerce across countries, brands, and content operations, BORN is one of the few firms that can staff the whole program.
Best for: Fortune-scale manufacturers running multi-year, multi-country programs. Not for: the mid-market; you would be a small fish.
What manufacturers should budget
Ranges we consistently see for US manufacturer implementations: $150,000 to $500,000+ for a full B2B build on Adobe Commerce or Shopware, with $30,000 to $150,000 of that in ERP integration; $10,000 to $40,000 for paid discovery; and $5,000 to $25,000 per month for ongoing support and optimization. Productized options shift the math: a managed SAP portal like Corevist trades lower time-to-launch for platform lock-in, and an integration layer like DCKAP Integrator can solve a data problem for a fraction of a rebuild. The budget rule that matters most: roughly 60% of a custom build should go to integration and data work. If a proposal spends 80% on design and frontend, you are reading a B2C proposal with the logos swapped.
Pitfalls: how manufacturers pick the wrong agency
B2C agencies pretending to be B2B
The most common failure mode. The portfolio is beautiful: beauty brands, apparel, DTC startups. The proposal leads with design and brand. Nobody asks which ERP you run until week six. The tell is simple: a real B2B agency asks about your ERP, your pricing rules, and your dealer structure in the first conversation, because those determine feasibility. We listed more tells in our B2B ecommerce best practices guide.
Offshore time zones versus plant-floor stakeholders
Several popular “top B2B agency” lists rank offshore outsourcing firms highly on cost. Here is what the lists do not model: your requirements live in the heads of your inside sales team, your warehouse manager, and your controller, and those people work plant hours, not 9 p.m. video calls. B2B builds fail on requirements, and requirements fail across ten time zones. Offshore teams can maintain a settled system; they should not design your integration.
Platforms and marketing firms miscounted as builders
Competing lists routinely include commerce platforms (software you license, not firms that build) and demand-gen agencies (who run ads, not integrations) alongside actual implementers. All three have a role, but if you need a storefront wired to an ERP, two of the three cannot help you, and the list will not tell you which two.
Fixed bids before discovery
A firm fixed price quoted before anyone has examined your ERP customizations is either padded or a change-order trap. Pay for discovery. It is the cheapest insurance in this industry.
What we’ve learned building for manufacturers and distributors
Across 50+ B2B implementations, the manufacturer-specific lessons that repeat:
By sector, we also publish focused guides for industrial & MRO, medical & lab equipment, and electrical & lighting distributors.
- The part number is sacred. Customers search by your part number, their part number, and competitor cross-references. Search that only matches your catalog’s display names will be abandoned within a month.
- Dealers adopt portals that are faster than phone calls, and ignore everything else. Adoption is a performance requirement, not a training requirement.
- Contract pricing must come from the ERP, live. The first time a dealer sees a wrong price on the portal, they go back to calling their rep, and you have lost the channel for a year.
- Phase the launch. Core catalog and reordering first, configurators and punchout second. Manufacturers who try to launch everything at once launch nothing.
- History migrates. One of our replatforms preserved 16 years of customer and order history with zero downtime. Your dealers’ reorder history is the moat; never accept losing it.
How to run the evaluation
We published a full framework in how to evaluate a B2B ecommerce agency, and it was written to be run against us too. Condensed for manufacturers: ask every candidate what percentage of their projects involve ERP integration (above 70% signals a real B2B shop); make them name the ERPs they have integrated with project counts; ask the trap question, “Can you name the developer who will build our integration?”; and apply the 60/40 budget rule. Two or more red flags (design before ERP questions, “we integrate with anything,” fixed pricing without paid discovery, no nameable integration developer, no honest failure stories) means keep looking, even if the agency is on this list.
Talk to a team that builds for manufacturers
If you are a manufacturer or distributor scoping an ecommerce build, replatform, or dealer portal, we will give you a straight assessment, including when Corevist, DCKAP, or one of the other firms above is the better call for your situation. Bring your ERP details, your SKU count, and your channel structure; we will tell you what the project actually looks like. Book a consultation with Web Solutions NYC.
Frequently Asked Questions
It depends on your ERP and your model. Manufacturers on SAP who want a fast managed portal should look at Corevist. Distributors with data-flow problems should look at DCKAP. Manufacturers who need a custom Adobe Commerce or Shopware build with deep ERP integration should shortlist Web Solutions NYC, Atwix, Classy Llama, and IronPlane. Global enterprises should evaluate Vaimo and BORN Group. Judge every candidate on named ERP experience and manufacturer case studies, not partner badges.
Manufacturers add four requirements most B2B projects lack: dealer and distributor channel support (with the politics that come with it), configure-price-quote workflows for configured products, MAP pricing enforcement, and very large long-tail SKU catalogs. All four sit on top of the standard B2B baseline of company accounts, contract pricing, and real-time ERP integration.
A full custom implementation typically runs $150,000 to $500,000 or more, with $30,000 to $150,000 of that in ERP integration and $5,000 to $25,000 per month in ongoing support. Productized routes cost less up front: managed SAP portals like Corevist quote 30 to 90 day implementations, and integration platforms like DCKAP Integrator can fix data flow without a storefront rebuild.
Usually both, deliberately. The platform decisions that make this work include dealer-specific pricing and catalogs, MAP-compliant price display, territory logic, and sometimes routing ecommerce leads to channel partners. The mistake is letting an agency that has never handled channel conflict design it by accident. Make channel strategy an explicit discovery topic before any design work starts.
For the initial build, we advise against it. Requirements discovery needs your inside sales, warehouse, and finance people in the room during their working hours, and those stakeholders cannot do recurring late-night calls across ten time zones. Offshore teams are a reasonable choice for maintaining a system after the architecture and integrations are settled.
The ones you already run. Common systems we see in manufacturing and distribution are SAP, NetSuite, Microsoft Dynamics, Acumatica, Sage, Epicor P21, and Infor. What matters more than the logo is the integration design: bidirectional and near-real-time for inventory, contract pricing, credit limits, order status, and shipment tracking. Nightly batch sync produces wrong prices and oversold inventory, and dealers stop trusting the portal fast.
