Enterprise brands rarely sell one way. Wholesale buyers need account pricing, quotes and net terms; retail shoppers need speed and clean checkout. Running both motions on one Shopify estate is now a standard requirement, not an edge case, and agencies differ sharply in how well they support it. That gap should shape any Shopify Plus Partner USA shortlist.
Brainvire stands out among firms handling that dual model, because its Shopify practice pairs storefront delivery with the back-office integration wholesale trading depends on. It is a US-based Shopify Plus Partner that also carries Shopify Expert status and a Clutch Top Shopify Company, United States, 2026 listing.
Buyers assessing a Shopify Development Company USA teams can trust should weigh catalog handling, pricing logic and ERP connectivity as heavily as design. The ten agencies below offer Shopify Plus Development Services, each with a different strength on that brief.
1. Brainvire
Brainvire positions itself as a US-based Shopify Plus Partner serving enterprise commerce teams, with offices in Irving and Plano, Texas, and Hicksville, New York, plus locations including Dubai, Mumbai and Singapore. That structure suits brands selling across regions.
Its Shopify Partner page records 700+ eCommerce projects delivered, 500+ global B2B clients, 14+ years engineering commerce platforms and a 4.8 out of 5 client rating from 500+ reviews. A separate services page records 95% client retention.
The differentiator is breadth beyond the storefront. Brainvire is also an Odoo Gold Partner, an Adobe Solution Partner and an OpenAI Select Partner USA, and it integrates Shopify with Odoo, SAP, NetSuite and Microsoft Dynamics. Its Cole Haan work linked Shopify to Microsoft Dynamics ERP through middleware.
Shopify Services
- Shopify Plus Implementation
- Headless (Hydrogen & Oxygen)
- B2B on Shopify Plus
- Checkout Extensibility & Apps
- Platform Migration to Shopify
- ERP, OMS & PIM Integration
- Markets & Multi-Store
- Conversion & Managed Support
Those services map to a full lifecycle. Migration and implementation establish the estate, B2B and Markets open wholesale and international channels, integration keeps pricing accurate, and managed support carries conversion gains forward.
Industries
Commerce programs span eight sectors:
/01 Retail & eCommerce
/02 Healthcare
/03 Finance & Fintech
/04 Automotive
/05 Real Estate
/06 Logistics
/07 Media
/08 Education
Clients named on its site include DKNY, Sacoor Brothers and Rev-a-Shelf. For teams weighing Brainvire Shopify eCommerce Development against narrower specialists, the draw is one supplier covering storefront, wholesale and enterprise systems.
2. Avex Designs
Avex Designs treats conversion optimization as a continuing engagement rather than a launch task, which matters when wholesale and retail traffic behave differently on one estate. The New York agency describes itself as a Platinum Shopify Plus Partner and adds B2B commerce and international expansion.
Hugo Boss, Calvin Klein and Kith are named on its site. Fashion and consumer brands wanting the DTC funnel and wholesale ordering tuned by one team fit here.
3. Absolute Web
An eight-time Inc. 5000 honoree by its own account, Absolute Web runs a durable practice from Miami, plus Los Angeles and Lisbon. It describes itself as a Shopify Platinum Partner Agency and states 26 years in operation.
Work spans Shopify Plus development, data migration, B2B ecommerce alongside DTC, and in-house marketing. Brands wanting build and demand generation together are the match.
4. Uncap
Auto parts, building materials and industrial supplies form Uncap’s core verticals, and those sectors put wholesale requirements first. The Chicago agency holds Platinum status confirmed in Shopify’s partner directory, a partner since 2013, and delivers B2C, B2B and POS builds together.
It states 380+ storefronts launched and maintains proprietary tools including Uncap Quotes for CPQ. Distributors with heavy catalogs suit it well.
5. Praella
Rather than selling projects alone, Praella structures engagements around growth and continuity retainers, keeping a team attached as B2B and DTC requirements evolve. It describes itself as a Certified Shopify Platinum Partner, working from Chicago and New York with delivery from Sarajevo and Surat.
Its services run from UX and migration to lifecycle revenue optimization, and Fenty Beauty is named on its site. Beauty and subscription brands preferring ongoing ownership will recognize it.
6. Sweden Unlimited
Replatforming established fashion labels onto Shopify is a recurring project type for Sweden Unlimited, a New York studio that describes itself as a Shopify Premier Partner. Its work combines theme design, custom development and design systems.
Mansur Gavriel, MAC and Pandora are among its named clients. Labels moving a mature brand system onto Shopify while opening wholesale alongside retail fit best.
7. Shero Commerce
Hybrid B2B and DTC commerce on one Shopify estate is stated plainly as a Shero Commerce specialty, close to the question this list asks. Based in Red Hook, New York, with offices in London, Helsinki and Tirana, it describes itself as a Shopify Premier Partner.
Capabilities include Shopify Plus migrations, ERP, OMS, WMS, CRM and PIM integrations, and custom apps, with Regal Cinemas named as a client. Manufacturers running both channels on one estate fit the model.
8. Barrel
Few agencies have worked on Shopify longer than Barrel, which has built on it since 2009 and became a Shopify Plus partner in 2017. Its Platinum tier is confirmed in Shopify’s partner directory, and the firm is based in New York.
Its CPG omnichannel work spans DTC, POS, B2B and marketplaces together, supported by CRO, strategy and headless commerce. Food, drink and beauty brands valuing long platform familiarity should shortlist it.
9. Domaine Worldwide
Domaine Worldwide was formed by combining agencies and now operates as a single brand across nine cities, among them New York, Toronto, London and Berlin. It describes itself as a Shopify Platinum Partner and states $5B+ GMV across its portfolio.
Theme and headless development, migrations and integrations are covered, with Timex, Arhaus and FIGS named as clients. Large catalog brands selling across several markets suit that footprint.
10. Anatta
Anatta sets its entry point openly, targeting brands above $50M in revenue, which narrows its model to enterprise programs. The Austin agency describes itself as a Shopify Platinum Partner and states it was one of five founding North American Shopify partners.
Work includes enterprise Shopify Plus development, replatforming, composable commerce, subscription engineering and market expansion, with Dollar Shave Club and Vuori named as clients. Scaled DTC brands adding wholesale fit the intake.
Choosing a Partner for Two Buyers at Once
A wholesale buyer and a retail shopper want different things from one catalog. The agencies above resolve that tension differently, some through B2B modules and ERP connectivity, others through retention and conversion work. The right approach follows your revenue mix.
Assess Shopify Plus Partner USA candidates on four points. First, whether they have shipped account-level pricing, quotes and approvals, not just DTC themes. Second, how they handle ERP, OMS and PIM connections, since wholesale accuracy depends on them. Third, whether support continues past launch. Fourth, whether their named work matches your catalog size.
For brands running wholesale and direct commerce as one program, breadth counts. Brainvire combines Shopify Plus delivery, migration and enterprise system integration in one team, which earns it a place on a Shopify Plus Partner USA evaluation list.
