Best Shopify B2B Agencies in 2026: 10 Compared

Last updated: October 29, 2026 · 18 min read · By Joe McFerrin, CEO of IWD Agency

Choosing a Shopify B2B agency comes down to one question: who has already solved your hardest workflow? Turning on Shopify's company accounts takes an afternoon. Syncing contract pricing from your ERP, letting a school district pay a purchase order on net 30 terms, keeping a tax-exempt library from being charged sales tax, and quoting LTL freight on a pallet of shelving are where B2B projects succeed or stall.

This guide compares 10 agencies with verifiable, current Shopify B2B work, judged against a real brief: a US manufacturer selling to libraries, schools and other institutions that needs company accounts, customer-specific pricing and catalogs, quotes, purchase orders and net terms, tax-exempt checkout, LTL freight for bulky products, configurable products and ERP integration. Every competitor fact was checked on the agency's own site or Shopify Partner Directory profile on October 29, 2026.

Disclosure up front: IWD Agency publishes this guide. We are a Shopify Plus agency that also builds on Adobe Commerce and BigCommerce, and our live Shopify B2B record is thinner than our Adobe Commerce B2B record. Our profile says so, and the decision framework names a competitor whenever one is the better fit. To see real stores first, read our Shopify B2B examples; for a general shortlist, see the best Shopify Plus agencies.

The 30-Second Verdict

If you are scanning:

• US manufacturers and distributors with big catalogs, contract pricing and an ERP: Uncap, BlueSwitch, Fyresite
• Quotes and RFQs for institutional or capital-equipment buyers: Uncap, Fyresite
• Brand-led B2B and trade programs: Domaine, Avex
• Leaving Magento with custom B2B pricing logic: Shero Commerce, Swanky
• ERP integration is the hard part, or Shopify Plus versus Adobe Commerce is still open: IWD Agency
• Selling B2B in the UK, Europe or Australia as well as the US: Swanky, Eastside Co
• Published entry pricing before the first call: Absolute Web, Avex, Swanky

#	Agency	Best for	Company size fit
01	IWD Agency	ERP-heavy B2B, platform decision still open	Mid-market to enterprise
02	Uncap	Manufacturers and distributors, ERP sync, quotes	Mid-market
03	BlueSwitch	Industrial and manufacturing replatforms	Mid-market to enterprise
04	Fyresite	Parts catalogs, configurable products, custom ERP connectors	Mid-market
05	Domaine	Brand-led B2B and trade programs	Upper mid-market to enterprise
06	Shero Commerce	Magento to Shopify B2B with custom pricing	Mid-market
07	Swanky	B2B with credit and ERP rules, UK, Australia, France	Mid-market
08	Eastside Co	Dedicated wholesale storefronts, London and New York	Small to mid-market
09	Absolute Web	DTC-first brands adding a professional channel	Mid-market
10	Avex	Design-led brands adding wholesale	Mid-market to enterprise

The numbers are for navigation. IWD is listed first because we publish this page, not because we have the most Shopify B2B launches; of the agencies we reviewed, Uncap and BlueSwitch publish the most named Shopify B2B work for manufacturers.

How to Judge a Shopify B2B Agency

Score every candidate on these six dimensions before you compare logos.

1. Named Shopify B2B work. Live storefronts on Shopify's native B2B, with the client named. A DTC portfolio with a wholesale password page is not B2B evidence.
2. Workflow coverage. Ask the agency to sort your list (pricing, quotes, terms, tax exemption, freight, configurable products) into native, app or custom on the first call.
3. ERP and integration depth. Prices, credit limits and invoices usually live in the ERP, and the integration is where B2B budgets slip. Good Shopify integration services teams name the connector, which system owns each record, and who supports it after launch.
4. Partner status, read correctly. Shopify's directory tiers partners (Plus, Premier and Platinum, for example) on their history and results on the platform. Tier is a filter, not proof of B2B skill: several Platinum partners we reviewed had no named B2B work.
5. US presence. B2B launches involve your ERP admin, finance team and freight carrier, so US business hours matter.
6. Fit by company size. Match the agency's usual client to your revenue, catalog size and internal IT capacity.

What Shopify B2B Does Natively in 2026, and What Still Needs an App

Agencies quote different scopes for the same brief because they disagree about what Shopify does out of the box. This is the current state from Shopify's documentation, checked October 29, 2026. B2B now runs on the Basic, Grow, Advanced and Plus plans, but several features manufacturers need are Plus only.

Buyer workflow	Native on Shopify (plan)	What usually gets added
Company accounts and locations	All B2B plans, with two location roles: location admin and ordering only	ERP sync of company records; multi-step buyer approvals need an app or custom work
Customer-specific catalogs and pricing	Catalogs on all B2B plans; Basic, Grow and Advanced allow 3 active catalogs across B2B markets; direct assignment to a company or location, and unlimited catalogs, are Plus only	ERP-driven price sync when you have hundreds of contract price lists
Quantity rules and volume price breaks	All B2B plans	Usually nothing
Quotes	Draft orders with custom or locked prices, sent as invoices; buyers can submit orders as drafts for your review	An RFQ or CPQ app, or custom work, for buyer-initiated quotes
Purchase orders and net terms	PO numbers, net terms, payment reminders, vaulted cards and ACH (US) on all B2B plans; deposits and partial payments are Plus only	Invoice and AR sync to the ERP
Tax-exempt checkout	Per-location tax ID and setting: collect, don't collect, or collect unless exemptions apply; US exemption codes are state reseller codes only	Certificate collection and renewal in a tax app or the ERP
LTL freight	No native LTL rating; third-party carrier-calculated shipping is included on Advanced and Plus, and Grow can add it	An LTL rating app or shipping rules engine, plus freight class and dimensions per product
Configurable products	Up to 3 options and 2,048 variants per product	A configurator app or custom build beyond that
ERP integration	Shopify names Acumatica, Microsoft Dynamics 365 and Celigo as B2B integration partners	A connector, iPaaS or custom middleware

For an institutional seller, three details matter most. Assigning a catalog directly to one school district or library system is a Plus feature. A public library is not a reseller, so it is usually set to "don't collect tax" at the company location, with its certificate kept outside Shopify. And nothing native rates LTL freight. Shopify also lists accelerated checkouts (Shop Pay, Apple Pay, Google Pay), local delivery and subscriptions as unsupported with B2B, and caps orders at 500 line items.

The 10 Shopify B2B Agencies, Profiled

Every agency below shows current, named Shopify B2B work on its own site or Shopify Partner Directory profile. Tiers are stated as the directory or the agency stated them on October 29, 2026. We include pricing wherever an agency publishes it on its site or directory profile.

01. IWD Agency

Website: iwdagency.com

Shopify partner status: Shopify Plus partner, listed as a Plus Partner in the Shopify Partner Directory. Also an Adobe Commerce partner and a BigCommerce partner, so our platform advice is not one-sided.

Headquarters: Austin, Texas, with a team in Barcelona. Founded 2008.

Specialties: B2B builds where the ERP is the system of record. Our deepest B2B and ERP work is on Adobe Commerce: Daniels Manufacturing (DMC) on Infor SyteLine and Warner Press on Sage Intacct. On Shopify, we are building a Shopify Plus B2B store for Europa Eyewear. We also run a YouTube channel of Shopify B2B reviews and demos. Senior engineers do the work, and about 94% of our clients stay with us after launch.

Honest limits: Our live Shopify B2B launch record is thinner than Uncap's or BlueSwitch's. If you want the agency with the most named Shopify B2B launches for manufacturers, start with them.

Best for: B2B companies whose ERP integration is the hard part, and teams still choosing between Shopify Plus, Adobe Commerce and BigCommerce.

02. Uncap

Website: uncap.com

Shopify partner status: Platinum Partner in the Shopify Partner Directory, a partner since May 2013.

Headquarters: Chicago, Illinois. Its About page lists a team of 22.

Specialties: B2B for manufacturers, distributors and wholesalers, sold as fixed-scope projects, plus its own Shopify apps: Uncap Connect (embedded ERP integration), Uncap Quotes (quote-to-cash CPQ), Uncap Garage (vehicle fitment) and Uncap Diagrams (shop-by-diagram parts ordering). Its directory listing names NetSuite, Dynamics, Acumatica, Epicor, Infor and Sage.

Named B2B work: ULE Group, an electrical and lighting distributor with more than 250,000 SKUs on Shopify B2B, synced from Epicor ERP with ShipperHQ for shipping. Farmers Depot, a Shopify Plus B2B store on Microsoft Dynamics 365 F&O through APPSeCONNECT. Kooks Headers & Exhaust, retail and wholesale on one store with Infor Visual ERP. Canon Medical Systems, a B2C checkout plus an institutional request-for-quote funnel for capital equipment built on Uncap Quotes.

Best for: US manufacturers and distributors with large catalogs, contract pricing and a mid-market ERP. The Canon Medical quote funnel is the closest published match we found to institutional selling.

03. BlueSwitch

Website: blueswitch.com

Shopify partner status: Platinum Partner in the Shopify Partner Directory, a partner since December 2013.

Headquarters: New York, New York.

Specialties: Large B2B and B2B-plus-DTC replatforms, a Unified Commerce Suite of reusable modules for checkout, onboarding, ordering and inventory, and ERP, PIM, CRM, OMS and 3PL integrations. Its About page cites industrial and manufacturing clients in both B2B and DTC.

Named B2B work: Sunnen Products Company (replatformed from Optimizely to Shopify B2B), True Manufacturing, Rapiscan Systems, Oldach HVAC Supply (legacy systems and complex shipping), L&R Distributors (shipping and fulfillment), CNC Supply Solutions (large catalog and order routing), TRC Electronics (customer-specific buying), Bags in Bulk (bulk ordering and volume discounts), T&T Plastic Land (product customizer) and European Wax Center.

Best for: Manufacturers and industrial distributors replacing a legacy B2B platform, especially with complex shipping, large catalogs or product customization. It publishes the longest list of named manufacturing B2B case studies we found.

04. Fyresite

Website: fyresite.com

Shopify partner status: Describes itself as a Shopify Premier Partner that has completed Shopify's available B2B certifications.

Headquarters: Tempe, Arizona, with Los Angeles, San Francisco and Denver also listed.

Specialties: Shopify Plus B2B for parts-heavy and industrial catalogs, custom apps and ERP connectors, and a parts offering called Fyresite Parts Intelligence. Its B2B page lists multi-tier pricing, restricted catalogs, quote builders, deposit flows and approval workflows, and names NetSuite and Epicor as common integrations.

Named B2B work: Chassis Unlimited (Magento to Shopify Plus), Clé Tile (B2B with a custom calculator app), Pooltables.com (custom ERP connector app and variation tooling) and NIS America (bidirectional NetSuite integration through Celigo).

Published timelines: One to four months for B2B projects, documented in an SOW after discovery.

Best for: Mid-market manufacturers with configurable or calculated products and a NetSuite or Epicor back office, especially in the western US.

05. Domaine

Website: domaineworldwide.com

Shopify partner status: Platinum Partner in the Shopify Partner Directory.

Headquarters: New York, its directory primary location, with Los Angeles and Amsterdam also shown on its site.

Specialties: Brand-led Shopify builds with a dedicated B2B practice. Its B2B page lists bundles, kits and assemblies, contract and tiered pricing, approval flows and credit terms, LTL and FTL freight with multi-warehouse routing, and tax and export compliance, alongside ERP, OMS and PIM integrations. Its portfolio also includes a multi-brand Shopify architecture for custom-priced products at Hunter Douglas.

Named B2B work: Industry West, a furniture brand, launched its trade program on Shopify B2B with volume pricing, quantity rules and B2B sign-up, replacing an offline sales process. Domaine also lists DTC-plus-B2B work for Tea Forté and Olaplex.

Best for: Upper mid-market and enterprise brands whose B2B buyers expect consumer-grade design, such as trade programs and design-led manufacturers. It is one of the few agencies we reviewed that names LTL freight on its B2B page.

06. Shero Commerce

Website: sherocommerce.com

Shopify partner status: Platinum Partner in the Shopify Partner Directory.

Headquarters: Red Hook, New York.

Specialties: Shopify Plus for B2B and DTC brands, a large migration practice (Magento, BigCommerce, Salesforce Commerce Cloud, WooCommerce and others), a B2B readiness audit, and integrations including NetSuite, SAP, Microsoft Dynamics 365 and Acumatica.

Named B2B work: Painful Pleasures, replatformed from Magento to Shopify with custom B2B features, bulk ordering and intricate pricing logic. STX, a sports equipment manufacturer, moved from Magento to Shopify.

Best for: Mid-market brands leaving Magento whose B2B pricing logic has to survive the move.

07. Swanky

Website: swankyagency.com

Shopify partner status: Platinum Partner in the Shopify Partner Directory.

Headquarters: Exeter, United Kingdom, with offices in Australia and France. No US office is listed.

Specialties: B2B on Shopify Plus as a named service, blended or dedicated B2B stores, iPaaS integrations, and migrations from Magento and Adobe Commerce.

Natural Instinct, migrated from Adobe Commerce B2B to Shopify Plus. Also ePackageSupply and Anagenics.

Published pricing: Its directory profile lists a price range starting from $1,500.

Best for: Brands selling B2B in the UK, Europe or Australia as well as North America, and buyers on credit limits. US-only sellers should weigh the time zone gap.

08. Eastside Co

Website: eastsideco.com

Shopify partner status: Describes itself as a Shopify Platinum Partner and one of the first three UK agencies accredited as a Shopify Plus Partner.

Headquarters: London, with offices in New York and Dubai.

Specialties: Full-service Shopify Plus design, development and marketing, with a B2B practice built around the choice between one blended store and a dedicated wholesale store.

Named B2B work: Coffee Angel, a Dublin coffee roaster with a trade business supplying cafes and offices. Eastside rebuilt the DTC store, cloned it into a dedicated Shopify wholesale store, and added a B2B commerce app so trade pricing and ordering sit behind a login.

Best for: Small and mid-market brands adding a separate wholesale storefront next to DTC. Its published B2B work is lighter on ERP integration than the US specialists.

09. Absolute Web

Website: absoluteweb.com

Shopify partner status: Platinum Partner in the Shopify Partner Directory, a partner since March 2015.

Headquarters: Miami, Florida.

Head-to-Head Comparison of IWD and the Five US B2B Specialists

This matrix covers IWD and the five US agencies on this list with the most named Shopify B2B work; Swanky, Eastside Co, Absolute Web and Avex are profiled above. Scores are based on published evidence only, so a low score can mean "not shown publicly" rather than "cannot do."

Capability	IWD	Uncap	BlueSwitch	Fyresite	Domaine	Shero
Named, live Shopify B2B launches	★★	★★★★★	★★★★★	★★★★	★★★★	★★★
Manufacturer and distributor clients	★★★★	★★★★★	★★★★★	★★★★	★★★	★★★
ERP integration depth (any platform)	★★★★	★★★★★	★★★★	★★★★	★★★	★★★
Quotes and RFQ tooling	★★	★★★★★	★★★	★★★★	★★★	★★
Freight and complex shipping	★★	★★★★	★★★★	★★★	★★★★	★★
Platform-neutral advice	★★★★★	★	★	★	★	★
US base	Austin	Chicago	New York	Tempe	New York	Red Hook, NY

★★★★★ deepest published evidence on this list · ★★★★ strong · ★★★ competent · ★★ limited or in progress · ★ not shown

IWD's two stars on Shopify B2B launches reflect that our named Shopify Plus B2B build, Europa Eyewear, is still in progress. Our ERP score is four stars, not five, because our ERP proof is on Adobe Commerce, not Shopify.

What a Shopify B2B Build Actually Costs

Shopify B2B projects usually cost less than equivalent Adobe Commerce builds because hosting, checkout and core B2B features come with the platform. The integration and the workflow gaps are where budgets move. IWD's estimates of typical market brackets for US agencies in 2026 (offshore and hybrid shops typically price lower):

Engagement type	Low	High	Typical timeline
Add native B2B to an existing Shopify store	15K	50K	4 to 8 wks
New Shopify Plus B2B storefront, blended or dedicated	75K	250K	12 to 22 wks
Replatform from Magento or a legacy B2B portal	100K	300K	16 to 28 wks
ERP integration through a connector or iPaaS	15K	60K	6 to 12 wks
Custom bidirectional ERP integration	40K	150K	10 to 20 wks
Quote, RFQ or product configurator work	15K	80K	4 to 12 wks
Ongoing retainer (mid-market)	5K/mo	25K/mo	ongoing

These are IWD's estimates of typical market ranges, not quotes from any agency on this list, and real projects vary. What moves them most: the number of contract price lists, how many records the ERP owns, freight rules (freight class, liftgate, delivery appointments) and product configuration beyond three options. The Shopify plan is a separate line.

Is Shopify the Right Platform for Your B2B Store?

Most agencies on this list focus on Shopify alone, so their answer will usually be yes. The honest split:

• Shopify B2B fits when: your pricing maps to catalogs and price lists, buyers mostly self-serve, you want DTC and B2B in one admin, and the ERP keeps the complicated logic.
• Look hard at Adobe Commerce or BigCommerce when: you need deep company hierarchies, negotiable quotes, requisition lists and purchase approval rules out of the box (all native in Adobe Commerce B2B), or orders beyond Shopify's 500-line-item limit.

Our Shopify Plus vs Adobe Commerce and Shopify Plus B2B vs BigCommerce B2B Edition comparisons cover the trade-offs in detail.

Decision Framework

Questions to Ask Every Shopify B2B Agency

1. Which live Shopify B2B stores have you launched in the last 24 months? Ask for URLs and a reference you can call.
2. For each item on our list, is it native, an app, or custom? Listen for specific answers on catalogs, quotes, terms, tax and freight.
3. Which Shopify plan do we need, and why? Direct catalog assignment, deposits and partial payments are Plus only.
4. How will you handle tax-exempt customers? Shopify's US exemption codes cover resellers only, so ask where institutional exemption certificates will live.
5. How will freight be priced at checkout? Which app or rules engine, which carriers, and how freight class and liftgate are handled.
6. How will quotes work? Draft orders, a quote app or custom CPQ, and who approves on each side.
7. How will purchase orders and net terms reach our ERP? Ask which system creates the invoice and which records the payment.
8. How will you model our configurable products? Shopify allows 3 options and 2,048 variants per product.
9. Which ERPs have you integrated with Shopify B2B, with named projects? And who supports the integration after launch?
10. Who exactly works on our account? Names, roles and hours.

How We Scored This List: Methodology

Six checks, applied to every agency including IWD:

1. Partner verification. Tier read from each agency's Shopify Partner Directory profile where we could find one (IWD's lists it as a Plus Partner), otherwise from the agency's own site, on October 29, 2026, and stated exactly as written.
2. Named Shopify B2B work. Named clients or case studies on the agency's site or directory profile. Agencies without named, current Shopify B2B work were left out.
3. Workflow coverage. Published evidence for contract pricing, quotes, terms, tax exemption, freight and configurable products.
4. ERP depth. Named ERPs in named projects scored above capability lists.
5. US presence. Offices as listed by the agency or the directory.
6. Company size fit. Inferred from client rosters, published team size and published pricing.

Reviewed and left out: BVA (bvaccel.com now redirects to Accenture), We Make Websites (its Shopify Partner Directory profile now shows BORN), Electric Eye (it describes its typical clients as DTC lifestyle brands), Fuel Made and Blend Commerce (conversion specialists without published B2B builds), Praella (a Chicago Platinum Partner whose featured work we could not tie to a named B2B build), and Charle and Ask Phill (credible partners whose work centers on UK and European brands). Each may suit other briefs.

Disclosure: IWD Agency publishes this guide and lists itself first. Where a competitor fits better, the decision framework says so by name. If you think a placement is wrong, send us the evidence and we will re-score.

Frequently asked questions

Which is the best Shopify B2B agency in 2026?

It depends on your hardest workflow. For US manufacturers and distributors with an ERP, Uncap and BlueSwitch publish the most named Shopify B2B work. For configurable products, Fyresite. For brand-led trade programs, Domaine. If ERP integration is the hard part, or the platform is still open, IWD Agency.

Do I need Shopify Plus for B2B?

Not always. Shopify offers B2B on the Basic, Grow, Advanced and Plus plans. Plus is required for assigning catalogs directly to a company or location, unlimited catalogs, deposits, partial payments and payment requests per fulfillment; the lower plans allow three active catalogs across B2B markets. If each institution needs its own catalog or pricing, plan on Plus.

Can Shopify B2B handle tax-exempt schools and libraries?

Yes, with setup. Each company location has a tax ID and a tax setting: collect tax, don't collect tax, or collect unless exemptions apply. Shopify's built-in US exemption codes are state reseller codes, so a public school or library is usually set to don't collect tax, with certificates managed in a tax app, the ERP or an offline process.

Can Shopify quote LTL freight at checkout?

Not natively. Third-party carrier-calculated shipping is included on the Advanced and Plus plans (Grow can add it for a fee or with annual billing), and LTL rates come from a shipping app or rules engine that uses it. Each product also needs freight class, weight and dimensions.

Does Shopify B2B support quotes, purchase orders and net terms?

PO numbers, net terms, payment reminders, vaulted cards and ACH are native on all B2B plans. Quotes work natively through draft orders with custom or locked prices, and buyers can submit orders for your review. A buyer-initiated request-for-quote flow usually needs an app or custom work.

How much does a Shopify B2B agency cost?

By IWD's estimates of the US market, it typically costs 15K to 50K to add native B2B to an existing store, 75K to 250K for a new Shopify Plus B2B storefront, and 100K to 300K for a replatform. ERP integration typically adds 15K to 60K through a connector or 40K to 150K for custom sync. Absolute Web, Avex and Swanky publish starting prices on their directory profiles.

How long does a Shopify B2B build take?

By IWD's estimates, adding B2B to an existing store typically takes 4 to 8 weeks. A new Shopify Plus B2B storefront typically takes 12 to 22 weeks, and a replatform 16 to 28 weeks. Complex ERP integration and custom quoting add time. Fyresite publishes one to four months for its B2B projects.

Which ERPs integrate with Shopify B2B?

Shopify names Acumatica, Microsoft Dynamics 365 and Celigo as B2B integration partners, and agencies on this list publish Shopify B2B projects on Epicor, Infor Visual, Dynamics 365 F&O and NetSuite. Ask for a named project on your ERP.

Shopify Plus B2B or Adobe Commerce for a manufacturer?

Shopify Plus fits when pricing maps to catalogs and price lists, buyers self-serve, and the ERP holds the complex logic. Adobe Commerce fits when you need native company hierarchies, negotiable quotes, requisition lists and purchase approval rules. An agency that builds on both can make that call without a stake in the answer.
