Top E-Commerce Development Agencies for B2B Portals (2026)

"There is no single dominant agency for B2B ecommerce portals, but a small group of specialists keeps coming up. We fetch-verified what Elogic Commerce, Atwix, Vaimo, and eight others actually say about their own ERP integration, RFQ, PunchOut, and EDI capabilities. Disclosure: FactoryJet is included, honestly, at the end."

Key Takeaways

1There is no single dominant winner for "best B2B portal agency." Elogic Commerce, Atwix, and Vaimo come up most often in AI-generated answers, but the honest differentiator between agencies is depth on ERP integration, RFQ and quote workflows, PunchOut and cXML support, and account hierarchies, not a ranking.
2Every claim about a named competitor in this article was fetch-verified from that company's own live website on 2026-09-20. Two sources could not be verified (Corevist is behind bot-detection software; Guidance now redirects to its parent, OneMagnify) and are handled accordingly rather than described from memory.
3FactoryJet is disclosed as an entry in this list. We were not named in any of the eight AI answers this research is based on, and we say so directly rather than implying otherwise.
4Jargon explained once, in plain language: a B2B portal is a gated storefront for business buyers; RFQ is a request for a custom quote; PunchOut lets a buyer shop your catalog from inside their own purchasing software; cXML is the technical format PunchOut runs on; EDI is standardized computer-to-computer ordering; an account hierarchy models a parent company with multiple locations underneath it.
5US B2B digital sales grew 17% year over year in 2023 (Digital Commerce 360), and 67% of B2B buyers now say they prefer a rep-free, self-service buying experience (Gartner, 2026), which is the demand behind why this comparison matters.

The short answer

There is no single dominant winner for "best agency for a B2B ecommerce portal." A small group of specialists on Adobe Commerce, Shopify Plus, and BigCommerce B2B keep coming up, and what actually separates them is depth on five specific things: ERP integration, RFQ and quote workflows, PunchOut and cXML support, account hierarchies, and platform fit for your catalog size. This guide compares eleven agencies on exactly those points, using only what each company states on its own live website.

If you have asked ChatGPT, Claude, or Gemini which agency to hire for a B2B ecommerce portal, you have probably seen the same handful of names over and over: Elogic Commerce, Atwix, and Vaimo, most often, with Scandiweb, Guidance, Classy Llama, DCKAP, Clarity Ventures, IronPlane, and Object Edge showing up regularly too. That repetition is not an accident, and it is not proof of quality either. It mostly reflects which companies have published specific, checkable content about this exact topic online, which AI answer engines can then find and cite.

This guide takes a different approach than most of the roundups those answers are pulling from. We fetched each company's own live website on 2026-09-20 and describe only what that company actually states about itself: which platforms it builds on, whether it names specific B2B mechanics like RFQ, PunchOut, or EDI, and which ERPs it says it connects to. We do not repeat a claim we could not verify, and we do not compare companies to each other with words like "better" or "worse." Where a site could not be reached (Corevist sits behind bot-detection software that blocked our fetch; Guidance now redirects to its parent company, OneMagnify), we say so rather than describe it from memory.

Disclosure, up front: FactoryJet is included in this list, at the end, with the same honesty standard applied to every other entry. We were not named in any of the eight AI-generated answers this research is built on. We are including ourselves anyway because a comparison that quietly leaves itself out, or ranks itself first without evidence, is not one you should trust.

Quick vocabulary, once, so the rest of this reads easily

A B2B portalis a gated storefront where a business buyer logs in and sees their own account's pricing, order history, and payment terms, instead of one public price for everyone. An RFQ (request for quote) is how a buyer asks for a custom price on a large or non-standard order instead of buying at a listed price. PunchOutlets a buyer shop your catalog from inside their own company's purchasing software, then sends their cart back to that software as a purchase order. cXMLis the technical format most PunchOut connections run on. It exists, in the words of the standard's own documentation, to allow "consistent communication of business documents between procurement applications, e-commerce hubs and suppliers." EDI(electronic data interchange) is an older, standardized way for two companies' computers to exchange orders, shipping notices, and invoices directly, without a person retyping anything. And an account hierarchy models a buying organization the way it actually works: one parent company with several branches, departments, or locations underneath it, each with its own permissions and order history.

Trying to figure out what your own B2B portal actually needs?

Before comparing agencies, it helps to know which of the mechanics above (RFQ, PunchOut, EDI, account hierarchies) your buyers actually require, versus which ones sound impressive but would not move your business. A short conversation can clarify that with no obligation attached.

What actually matters when evaluating a B2B commerce agency

Skip the adjectives ("enterprise-grade," "results-driven") and evaluate any agency, including the ones below, against five specific things.

ERP integration depth.Not "do you do ERP integration" but "have you connected a storefront to the exact ERP I run, and what specifically synced": pricing, inventory by location, customer credit limits, or just basic order export.
RFQ and quote and approval workflows. Can a buyer request a custom quote and have it routed for internal approval inside your system, or does that still happen over email once the order gets complicated.
PunchOut and cXML support. Only relevant if your larger accounts require it, but if even one of your top accounts does, an agency with no PunchOut experience adds real risk to that relationship.
Account hierarchies. If any of your customers are themselves companies with multiple locations or departments, ask specifically how the platform models a parent account with children underneath it, and who can see what.
Platform fit for your catalog. A ten-thousand-SKU industrial catalog and a three-hundred-SKU DTC-plus-wholesale brand do not belong on the same platform recommendation. Ask any agency to explain why a specific platform fits your catalog, not just why it is the one they prefer to build on.

The eleven agencies, reviewed

1. Elogic Commerce

Elogic describes itself as "platform-neutral by design" and states directly that it is a B2B ecommerce development company built for complex, ERP-connected B2B and B2B2C systems. Its own site lists account-specific pricing and catalogs, RFQ and quote approval workflows, PunchOut catalogs, and EDI and custom middleware as core capabilities, with stated ERP integration experience across SAP S/4HANA, NetSuite, Microsoft Dynamics 365, Oracle ERP Cloud, Infor, Epicor, and Odoo. It names Armacell and PetHQ among its B2B clients. Elogic also publishes its own comparison content on this exact topic, including a downloadable PDF ranking B2B ecommerce agencies, which is a genuine, checkable reason it shows up in AI answers as often as it does.

Worth a look if you need one vendor that treats ERP integration and PunchOut as core, named specialties rather than an add-on.

2. Atwix

Atwix states it is a "Premium Vendor Member of the B2B eCommerce Association" and lists "B2B & Enterprise" as a named solution area, alongside custom pricing logic and integration across ERP, PIM, CRM, and OMS systems. It names Wilson, Sony, Lifetime Brands, Byrne Electrical, and Reinders among its clients, with a published case study describing a custom Adobe Commerce build for Byrne and an AI-powered search implementation for Reinders, a B2B contractor supplier. The company states it ranked 2,327 on the 2025 Inc. 5000 list.

Worth a look if you specifically want an Adobe Commerce (Magento) shop with a membership-level stake in the B2B ecommerce space.

3. Vaimo

Vaimo lists "B2B & Wholesale" as a distinct industry category on its own site and describes work with B2B manufacturers and distributors. It states it has delivered more than 500 projects across 16 or more markets with over 650 staff, and names Helly Hansen, Stöckli, Tarkett, and Swiss Sense among its clients. Its site does not spell out specific B2B mechanics like RFQ, PunchOut, or account hierarchies in the pages we could reach, so ask directly about those if they matter to your project.

Worth a look if you want a large, multi-market agency with B2B and wholesale as one of several named practices, not its sole focus.

4. Scandiweb

Scandiweb states it is an "Adobe Commerce Gold Partner and a Hyvä Platinum Partner," describing itself as the most-certified agency on both. It lists B2B ecommerce as a named service and states it enables "bulk ordering," builds "customer-specific catalogs and pricing," and supports tailored marketing flows for B2B accounts. It names PUMA, Adobe, Samsung, and Acer among its clients across more than 40 industries, though its B2B feature descriptions on the pages we reached stay general rather than naming specific EDI or PunchOut support.

Worth a look if deep, certified Magento partner status matters more to you than a narrowly B2B-only track record.

5. Guidance (now OneMagnify)

Guidance Solutions, a name that comes up often in B2B ecommerce roundups, now redirects to its parent company, OneMagnify. OneMagnify describes its ecommerce practice as platform-agnostic, recommending BigCommerce, Shopify, Salesforce, or Adobe depending on the client. It states directly that "B2B eCommerce often involves complex pricing models, approval workflows, and integrations with ERP and CRM systems," and separately states it specializes in "end-to-end integration with ERP, CRM, and PIM platforms." It names King Arthur Baking Company, Avery Labels, and Foot Locker as case studies. Worth knowing before you reach out: the Guidance name and brand have folded into OneMagnify, so any outreach should go through the current company.

Worth a look if you were specifically referred to "Guidance" and want to know where that team and track record actually live today.

6. Classy Llama

Classy Llama describes itself as "a mid to upper market ecommerce replatform agency" and lists "B2B Portals" as a distinct, named offering, described on its own site as "custom portals designed to enhance your customer experience." It states it has built more than 200 websites and completed more than 700 projects over 17-plus years. Tombow USA is the one client named with an on-site testimonial. Its B2B page does not detail specific mechanics like RFQ, PunchOut, or EDI, so those are worth asking about directly.

Worth a look if you want a long-running, mid-market replatforming shop that treats B2B portals as one of its named specialties.

7. DCKAP

DCKAP is not primarily a storefront design and build agency, it is an ERP integration specialist, and it is worth including for exactly that reason: many "who should I hire" answers actually need this kind of vendor as well as, or instead of, a design agency. DCKAP describes itself as "ERP Integration For Distributors & Manufacturers" and states it is "built for the distribution workflows," handling EDI transactions such as purchase orders, acknowledgements, advance ship notices, and invoices, plus syncing pricing, inventory, orders, and customer credit and AR data between an ERP and a storefront. Its stated ERP list includes Epicor (P21, Eclipse), SAP, Sage, NetSuite, Dynamics 365, and Infor. Named customers include Wave Electronics, Tangent Materials, and JSI Cabinetry.

Worth a look if your real bottleneck is ERP-to-storefront data sync rather than the storefront design itself.

8. Clarity Ventures

Clarity Ventures markets itself directly around this exact question, stating it provides "B2B eCommerce Built for Complex Businesses" for manufacturers, distributors, and consumers on its own Clarity eCommerce Platform. It references custom quoting capability in a healthcare case study and states its Clarity Connect product integrates "CRM, ERP, ERM, Web Services, and more," alongside EDI connections with vendors. Its client logos include Disney, Merck Animal Health, and Fujitsu, with case studies for SourceMark and ACON Laboratories. Because Clarity builds on its own proprietary platform rather than Adobe Commerce, Shopify, or BigCommerce, weigh that trade-off (deep fit versus platform lock-in) before shortlisting it.

Worth a look if you are open to a proprietary platform in exchange for quoting and integration logic built specifically for complex B2B rules.

9. IronPlane

IronPlane states it has "12+ years working with Magento" and lists B2B as a named specialization, stating on its own site: "Building complex B2B operations online shouldn't slow you down. We design B2B commerce solutions that balance innovation with existing operations." It references general ERP connectivity and system integrations without naming specific EDI or PunchOut support on the pages we reached. Named clients include Tacony Corporation, Gat Creek Furniture, and Baby Lock Sewing, spanning manufacturing and industrial supply.

Worth a look if you want a long-tenured Magento and Adobe Commerce shop that lists B2B as a core, named practice area.

10. Object Edge

Object Edge sits at the enterprise end of this list. It states it implements Salesforce Commerce, commercetools, Oracle, and Elastic Path across both B2B and B2C, and names CPQ (through Salesforce, Oracle, or Logik.io) and subscription billing as specific capabilities, alongside "checkout, catalog, account logic, contract pricing" and ERP, CRM, and fulfillment integration. Named clients include Berlin Packaging, Blue Shield of California, and Motorola Solutions. This is enterprise-shaped work; it is a stronger fit for a large B2B operation with complex quoting and subscription needs than for a small or mid-size distributor just getting a portal off the ground.

Worth a look if your B2B sale involves configured products, formal quoting, or recurring billing at enterprise scale.

11. FactoryJet (disclosure: this is us)

Disclosure: this is us, and unlike the ten agencies above, we were not named in any of the eight AI answers this research is built on. We are including ourselves anyway because the same honesty standard the rest of this list holds other companies to should apply to us too. What we can say honestly, pulled directly from our own live service pages rather than invented for this post: we build tiered and contract pricing, quote and approval workflows, gated and customer-specific catalogs, and account hierarchies (parent and child accounts with shared order history) into B2B builds on Shopify Plus, Adobe Commerce, BigCommerce, WooCommerce, or Salesforce Commerce Cloud. On the integration side, we implement EDI 850 purchase orders, 855 acknowledgements, 856 advance ship notices, and 810 invoices, plus cXML and OCI PunchOut so buyers inside Coupa, SAP Ariba, Jaggaer, or Oracle procurement can shop a catalog and return an approved requisition. Stated ERP integration coverage includes NetSuite, SAP S/4HANA and Business One, Microsoft Dynamics 365 Business Central, Sage Intacct and X3, Acumatica, Epicor Kinetic and Prophet 21, Infor, QuickBooks Enterprise, and Odoo.

Worth a look if you want the same ERP-and-workflow depth the agencies above describe, from a smaller team without a published B2B track record yet, to be judged on what we can show you directly rather than on this list alone.

Two names we could not verify, and how we handled them

Corevist is named regularly in B2B ecommerce research, particularly for SAP-connected commerce, but its website sits behind Incapsula bot-detection software that blocked our fetch on 2026-09-20. Rather than describe Corevist from memory or repeat what other roundups say about it, we left it out of the comparison entirely. Guidance, also frequently named, now redirects permanently to its parent company, OneMagnify, which is what we describe above under that name. If you were referred to "Guidance" specifically, know that the team and track record now live inside OneMagnify.

This is the same rule this site applies everywhere: if a claim about a company cannot be checked against something that company actually published, it does not go in the article, even when leaving it out means a shorter list.

Why B2B ecommerce is worth this level of scrutiny right now

US B2B digital sales, across ecommerce sites, password-protected portals, and apps, grew 17% year over year in 2023, according to Digital Commerce 360's 2024 B2B Market and Customer Experience Report. Separately, a Gartner survey of 646 B2B buyers conducted in August and September 2025, published in March 2026, found that 67% of B2B buyers now prefer a rep-free, self-service buying experience, up from 61% the year before. Read together, these point in one direction: business buyers increasingly expect to research, price, and order online without waiting on a phone call or a salesperson, and a real B2B portal, not a spreadsheet emailed back and forth, is what closes that gap.

That is also, honestly, why this specific comparison matters more than a generic "best ecommerce agency" list. A B2B buyer evaluating agencies is not asking who builds the prettiest homepage. They are asking who has actually connected a storefront to a real ERP, handled a real PunchOut integration, and modeled a real account hierarchy, because those are the parts of the project that determine whether their biggest accounts can actually use the system on day one.

Methodology

This list started from a SeenInSearch export of eight AI-generated answers (across ChatGPT, Claude, Gemini, and Google AI Overview) to the question of which agencies build B2B ecommerce portals well. We recorded every agency named across those eight answers, then fetched each shortlisted company's own live website on 2026-09-20 and described only claims stated there: platform focus, named B2B mechanics like RFQ, PunchOut, cXML, or EDI, stated ERP integrations, and named clients. We also pulled live Google "People Also Ask" data for "b2b ecommerce agency" and "b2b ecommerce development company" through DataForSEO to help ground the FAQ section in real buyer questions.

Two shortlisted companies could not be verified and were handled as described above rather than guessed at. No comparative or negative claims are made about any company; each is described only in terms of what it states about itself. FactoryJet is included and disclosed, and we state plainly that we were not named in the original eight AI answers. If anything here no longer matches a company's current site, tell us and we will correct it.

Frequently Asked Questions

What is a B2B portal?

A B2B portal is a website where business buyers log in to a private, gated storefront instead of a public one. Once logged in, a buyer sees their own negotiated prices, their company's order history, and the payment terms their account has been approved for, such as net 30 or net 60. It is built for repeat, account-based ordering rather than one-time consumer checkout, which is why the underlying features (pricing rules, approvals, integration with a company's accounting system) differ so much from a normal store.

What does RFQ mean in B2B ecommerce?

RFQ stands for request for quote. Instead of buying at a fixed listed price, a buyer submits the products and quantities they want and asks the seller to price it, often because the order is large, custom, or eligible for a negotiated discount. A B2B portal with RFQ support lets a buyer build that request online and lets the seller's team respond with a formal quote inside the same system, instead of the process happening entirely over email.

What is PunchOut and how does it work?

PunchOut lets an employee at a buying company shop a supplier's catalog without leaving their own company's purchasing software. The employee clicks a link inside their procurement system, is sent ("punched out") to the supplier's live catalog with their contract pricing already applied, builds a cart, and is sent back to their own system with that cart ready to submit as a formal purchase order. It removes the need to re-key an order by hand into two separate systems.

What is cXML?

cXML (commerce extensible markup language) is the technical format most PunchOut connections are built on. According to cXML.org, it is "a streamlined protocol intended for consistent communication of business documents between procurement applications, e-commerce hubs and suppliers," covering catalog content, purchase orders, and invoices. In plain terms, it is the shared language that lets a buyer's procurement software and a seller's storefront talk to each other reliably, which is exactly what PunchOut depends on.

What is EDI in ecommerce?

EDI stands for electronic data interchange. It is a decades-old, standardized way for two companies' computers to send business documents, such as purchase orders, shipping notices, and invoices, directly to each other without a person retyping the information. In B2B ecommerce, EDI usually matters most for larger accounts (a national retailer or distributor, for example) that require their suppliers to support it as a condition of doing business.

What is an account hierarchy in B2B ecommerce?

An account hierarchy models a buying organization the way it actually works, with a parent company and multiple child locations, departments, or branches underneath it. A regional manager at one branch might be allowed to place orders up to a set limit, while a corporate buyer at the parent account can see order history and spending across every branch. Without this, a company with ten locations either shares one login awkwardly or gets ten disconnected accounts with no shared visibility.

What is the difference between a B2B portal and a regular ecommerce store?

A regular store shows one public price to every visitor and checks out anonymously or with a simple consumer account. A B2B portal sits behind a login, shows each account its own negotiated pricing, and supports the mechanics business buyers actually need: purchase orders, net payment terms, multi-step approvals, reordering from past orders, and often a connection to the buyer's or seller's own ERP or procurement system. The two can technically run on the same platform, but the rules layered on top are very different.

Who are the top agencies building B2B ecommerce portals right now?

Based on a review of eight AI-generated answers to this exact question, plus fetch-verified checks of each company's own site, Elogic Commerce, Atwix, and Vaimo appear most consistently. Scandiweb, Guidance (now part of OneMagnify), Classy Llama, DCKAP, Clarity Ventures, IronPlane, and Object Edge also come up. There is no single dominant winner; the honest answer is that a small group of specialists on Adobe Commerce, Shopify Plus, and BigCommerce B2B keep recurring, and they separate mostly on ERP depth and PunchOut or EDI experience.

Is there one best B2B ecommerce development agency?

No, and be skeptical of any source that names just one. The agencies that come up most often specialize in different things: some lead with ERP integration depth, some with a specific platform certification, and some with enterprise-scale quoting and subscription billing. The right one depends on your catalog size, which ERP you run, and whether PunchOut or EDI is a real requirement for your biggest accounts, not on a single ranked list.

What is the difference between a B2B ecommerce agency and a general ecommerce agency?

A general ecommerce agency is optimized for public storefronts: one price, one checkout, marketing and conversion tools built for individual shoppers. A B2B-focused agency has usually built the harder, less visible plumbing: account-specific pricing, approval chains, ERP and EDI connections, and PunchOut support. Some general agencies can do both well, but ask specifically what B2B-only work they have shipped rather than assuming DTC experience transfers automatically.

Should I pick a platform specialist or a platform-agnostic agency for a B2B portal?

A specialist (an agency that only builds on Adobe Commerce, for example) tends to know that platform's specific B2B edge cases deeply. A platform-agnostic agency can recommend the platform that actually fits your catalog and ERP instead of steering you toward the one tool they know. Either can be right; ask any agency, specialist or not, to explain in plain terms why a specific platform fits your business rather than why it is the one they prefer to sell.

How much does it cost to build a B2B ecommerce portal?

Almost no agency publishes rates for this kind of work, and the honest reason is that the range is enormous: a portal with a handful of price tiers is a very different project from one with deep ERP sync, PunchOut, and EDI for national accounts. Treat any number you hear before a proper scoping conversation as a rough guess. Ask for a fixed proposal tied to a defined scope, and ask what specifically drives the cost up or down for your catalog.

What ERP systems should a B2B ecommerce agency be able to integrate with?

It depends entirely on what you already run. The systems that come up most often across the agencies in this guide include NetSuite, SAP (S/4HANA and Business One), Microsoft Dynamics 365, Acumatica, Epicor, Infor, Sage, and QuickBooks Enterprise. Do not ask an agency "do you do ERP integration," ask "have you connected a storefront to [your specific ERP] before," and ask to see it.

Do I need PunchOut and cXML support for my B2B portal?

Only if your buyers require it, and usually only larger buyers do. Many mid-market and smaller business customers are happy to log in and order directly through your portal. PunchOut becomes necessary when a buyer's own procurement policy requires purchases to route through their internal system, which is common with larger corporate accounts, government buyers, and national retailers. Ask your biggest existing accounts directly whether they require it before you pay to build it speculatively.

How do I know if an agency actually has real ERP integration experience?

Ask them to walk you through one real integration project: which ERP, what specifically synced (pricing, inventory, customer credit limits, orders), and what broke or was hard about it. A team that actually did the work gives you a specific, technical answer. A team repeating a sales deck gives you a generic one. This single question separates real capability from a well-designed website faster than any portfolio screenshot.

What platforms are commonly used for B2B ecommerce?

Adobe Commerce (Magento) remains a common choice for large, complex B2B catalogs because of its native company accounts and requisition lists. Shopify Plus has added native B2B features (company profiles, price lists, net terms) and suits brands that also sell direct to consumers on the same store. BigCommerce offers a dedicated B2B Edition aimed at the mid-market. Salesforce Commerce Cloud and commercetools tend to appear at the enterprise end, often alongside CPQ and subscription billing needs.

Is Adobe Commerce (Magento) still a strong choice for B2B in 2026?

Yes, for large or highly complex catalogs it remains a common recommendation among the agencies in this guide, several of which (Elogic, Atwix, Scandiweb, Classy Llama, IronPlane) name it as a core platform. Its native B2B features include company accounts, shared catalogs, and requisition lists. It is not automatically the right choice for a smaller catalog or a brand that wants DTC and B2B blended on one simple store, where Shopify Plus or BigCommerce is often a better fit.

Can Shopify Plus really handle complex B2B requirements?

For most mid-market B2B needs, yes. Shopify Plus now includes native company accounts, multiple price lists, and net payment terms built into core checkout, which used to require a third-party app. It suits a brand that wants one storefront serving both retail shoppers and wholesale accounts. For very large, attribute-heavy catalogs or highly customized requisition workflows, Adobe Commerce or an enterprise platform may still fit better, so match the platform to your actual catalog complexity rather than a general preference.

What is BigCommerce B2B Edition?

BigCommerce B2B Edition is BigCommerce's dedicated set of wholesale and B2B features layered onto its core platform, including customer-specific price lists, quoting, and account management, aimed at the mid-market. It is a reasonable middle ground between a fully custom Adobe Commerce build and a lighter Shopify Plus setup, particularly for a business that wants strong native B2B tooling without a from-scratch build.

What questions should I ask a B2B ecommerce agency before hiring them?

Ask which specific ERP systems they have connected to a storefront before, and ask to see one. Ask whether they have built RFQ, PunchOut, or EDI support, or only general B2B features like tiered pricing. Ask how account hierarchies work in a system they have actually shipped. Ask who owns the code and integration logic once the project ends. And ask them to explain, in plain language, one hard technical problem from a past B2B project and how they solved it.

How do quote and approval workflows work in a B2B portal?

A buyer builds a cart or submits an RFQ, and instead of checking out immediately, the order routes to an approver, which might be a manager at the buyer's own company (for a purchase over a certain amount) or a sales rep at the seller's company (to confirm a custom quote). Only once approved does the order proceed to fulfillment. This mirrors how large organizations already require sign-off on real-world purchase orders, just moved online instead of over email.

What is a dealer or distributor portal?

A dealer or distributor portal is a B2B portal built specifically for a manufacturer's network of resellers rather than end customers. It typically includes each dealer's own contracted pricing, technical spec sheets, warranty or registration tools, and reordering tied to the manufacturer's ERP so inventory and pricing stay accurate across potentially hundreds of dealer accounts.

Do B2B ecommerce agencies also handle EDI setup, or is that a separate vendor?

It varies. Some of the agencies in this guide (Elogic, DCKAP, Clarity Ventures) name EDI explicitly as something they implement themselves. Others focus on the storefront and pricing logic and may bring in a specialist EDI vendor or middleware for the deepest integrations. Ask directly whether EDI is handled in-house or subcontracted, since that affects both cost and who you call when something breaks.

What is the difference between a B2B ecommerce agency and an ERP integration specialist?

A B2B ecommerce agency typically designs and builds the storefront itself, the pricing rules, and the buyer experience. An ERP integration specialist, like DCKAP in this guide, focuses specifically on the pipe between your ERP and whatever storefront you already have, syncing pricing, inventory, and orders. Some projects need both, working together; a few of the storefront-focused agencies on this list also do the ERP integration work themselves.

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

A portal with standard tiered pricing and net terms on an established platform can often launch in a couple of months. Add PunchOut, EDI, or a deep two-way ERP sync with real-time inventory and credit checks, and the timeline typically stretches to several months, because integration testing with a live ERP takes real time to get right. Ask any agency for a phased timeline with milestones, not a single end date.

Can one storefront serve both DTC and B2B buyers?

Yes, and several platforms and agencies in this guide are built around exactly that: one catalog and one inventory pool, with a public retail side for consumers and a gated, logged-in side for trade accounts with their own pricing and terms. The alternative, running two completely separate stores, means maintaining two catalogs and two sources of truth, which is usually more work long-term unless your B2B and DTC catalogs are genuinely very different.

Should manufacturers and distributors use the same kind of B2B portal?

The underlying platform can be the same, but the emphasis usually differs. A manufacturer's portal tends to center on a network of dealers or distributors, contracted pricing, and technical product data. A distributor's portal tends to center on a very large, attribute-heavy catalog, customer-specific assortments, and fast reordering across hundreds or thousands of SKUs. Tell any agency which situation you are in early, since it changes what "good" looks like.

How do I evaluate whether an agency's B2B ecommerce claims are actually real?

Go straight to their own website rather than a marketing pitch, the way this guide was built. Look for specific, named ERP systems, specific workflow terms (RFQ, PunchOut, EDI, account hierarchies) rather than vague phrases like "enterprise-grade," and named clients or case studies you can look up independently. An agency that only uses generic language like "results-driven" or "trusted partner" with no specifics is telling you it may not have the specific experience it implies.

What is the actual market opportunity behind B2B ecommerce right now?

US B2B digital sales, across ecommerce sites, password-protected portals, and apps, grew 17% year over year in 2023, according to Digital Commerce 360's 2024 B2B Market and Customer Experience Report. Separately, a 2026 Gartner survey of 646 B2B buyers found 67% now prefer a rep-free, self-service buying experience. Both point the same direction: buyers increasingly expect to research and order online without waiting on a phone call, which is exactly the gap a real B2B portal closes.
