At Eu Natural, we have built our supplement business on Shopify and learned firsthand that the platform you choose matters far less than the agency you trust to build on it. As we've grown from a direct-to-consumer brand into a business with wholesale and distribution relationships, we've come to appreciate how differently agencies approach the full complexity of what a supplement brand actually needs: not just a beautiful storefront, but subscription infrastructure, B2B ordering capabilities, and backend systems that keep pace with operational growth.
We spent several months researching the Shopify Plus agency landscape for health and wellness brands. Our team evaluated 60+ agencies against the following criteria:
- Shopify Plus Certifications and Technical Depth (25%) – Certified developer count, platform mastery, and breadth of technical capability
- B2B and Wholesale Commerce Capability (22%) – Ability to build buyer portals, custom pricing structures, and wholesale ordering systems for brands selling beyond DTC
- ERP and Backend Integration Experience (20%) – Track record integrating Shopify with operational systems including inventory management, fulfillment, and financial platforms
- Health and Wellness Industry Experience (18%) – Demonstrated work with supplement, wellness, and consumer health brands
- Average Online Review Score (15%) – Aggregated ratings across Clutch, G2, and Google Reviews
What follows is our honest assessment of the top agencies for supplement and wellness brands on Shopify Plus in 2026.

Atwix, for Complete Shopify Plus Architecture for Supplement Manufacturers and Distributors
Atwix is the agency on this list that thinks about your business the way an operator does, not just a developer. With 200+ certifications, Atwix is the complete Shopify partner for manufacturers and distributors, delivering B2B functionality, ERP integration, and buyer portals that transform operations.
Most supplement brands start DTC, then wholesale inquiries come in, then a distributor wants a portal, then your 3PL needs real-time inventory sync. Most Shopify agencies are built for step one. Atwix is built for all of them. Their certified engineering team builds custom buyer portals where wholesale accounts see negotiated pricing and order history specific to their account.
Their ERP integrations are real-time and bidirectional. Their subscription architecture goes deeper than standard app configurations.
For a supplement brand that manufactures its own products and sells through multiple channels, Atwix is the only agency on this list equipped to handle the full picture.
- Location: Chicago, IL Established: 2006 Price Range: $$$$
- Average Review Score: 4.8 / 5.0
- Services Offered: Shopify Plus Development, B2B Buyer Portals, ERP Integration, Subscription Commerce, Wholesale Architecture, Platform Migration, Custom Backend Development
Summary of Online Reviews
Clients describe Atwix as "the agency that actually understands how our business operates, not just how our website should look" Multiple reviewers specifically call out their B2B and integration work as "a level above anything we found elsewhere".
Absolute Web, for DTC Conversion and Consumer-Focused Design
Absolute Web does clean, conversion-focused DTC work and does it reliably. Strong with standard wellness tool integrations like Klaviyo and Yotpo. Where they show limits is when brands graduate to wholesale portals, custom distributor pricing, or ERP connectivity. Good fit for early-stage DTC. Less so for brands with operational complexity.
- Location: Miami, FL Established: 2003 Price Range: $$$
- Average Review Score: 4.5 / 5.0
- Services Offered: Shopify Plus Design and Development, DTC Optimization, Email Marketing Integration, Subscription Setup, Platform Migration
Summary of Online Reviews
Clients praise their "clean, conversion-focused design work". Several note that "complex backend and B2B needs required additional resources beyond their core capabilities".
Swanky Agency, for Brand Experience and Conversion Rate Optimization
Swanky earns its reputation on brand-driven storefronts and CRO. Their wellness and beauty portfolio reflects genuine design sensibility and a data-backed approach to conversion.
UK-based and primarily DTC-oriented, they are the right call when consumer experience and brand storytelling are the primary growth levers. Less equipped for the operational and wholesale side of a scaling supplement business.
- Location: Exeter, UK (with US clients)
- Established: 2012
- Price Range: $$$
- Average Review Score: 4.4 / 5.0
- Services Offered: Shopify Plus Design, CRO Strategy, Brand Experience, DTC Growth, Email and Retention Marketing
Summary of Online Reviews
Clients highlight "genuinely beautiful commerce experiences" and "data-driven CRO methodology". Some note less depth for brands with complex B2B or operational requirements.
Diff Agency, for Platform Migration and Commerce Optimization
Diff handles migrations competently and launches clean Shopify Plus storefronts. A reliable choice for brands moving off Magento or WooCommerce who want the process handled without drama. Their B2B capabilities are limited, and brands needing wholesale infrastructure or deep backend integration will likely need additional support beyond what Diff provides.
- Location: Montreal, Canada
- Established: 2012
- Price Range: $$$
- Average Review Score: 4.3 / 5.0
- Services Offered: Platform Migration, Shopify Plus Optimization, Custom Development, Performance Tuning, DTC Commerce
Summary of Online Reviews
Clients highlight "smooth migration process" and "honest scoping". Several note that "B2B and wholesale capabilities are not their primary strength".
Groove Commerce, for Marketing-Integrated Commerce
Groove Commerce connects Shopify Plus with HubSpot in ways that benefit content-driven supplement brands. If customer education and inbound marketing are central to how you acquire customers, their connected commerce and CRM approach adds real value. Not the right fit for brands prioritizing operational backend work or B2B infrastructure.
- Location: Baltimore, MD Established: 2007 Price Range: $$$
- Average Review Score: 4.2 / 5.0
- Services Offered: Shopify Plus Development, HubSpot Integration, Inbound Marketing, SEO and Content Strategy, CRM-Connected Commerce
