What Makes a Great Shopify Plus Agency?

A great Shopify Plus agency does more than build themes. It operates as a strategic growth partner with deep platform expertise and the ability to execute across the full eCommerce stack. Here are the six criteria that separate the best from the rest:

• Official Shopify Plus Partner status. This isn't just a badge — Shopify vets Plus Partners for proven enterprise-level delivery, and Partners get early access to platform features, dedicated Shopify support, and priority merchant referrals.
• Migration experience. The ability to move stores from Magento, WooCommerce, BigCommerce, or custom platforms to Shopify Plus without data loss, SEO damage, or extended downtime. See our Magento to Shopify Plus migration guide for what that process looks like.
• CRO capability. Building a store is one project. Optimizing it for conversion is an ongoing discipline. The best agencies run hypothesis-driven A/B testing programs, not just design refreshes.
• Post-launch support. Launch day is day one, not the finish line. Look for agencies with structured retainer programs covering performance monitoring, iterative optimization, and feature development.
• Full-stack services. Agencies that handle development, design, CRO, paid media, email/SMS, and analytics reduce the coordination overhead of managing multiple vendors.
• Performance marketing integration. Your store and your ad spend should be aligned. Agencies that manage both can optimize the full funnel — from ad creative to landing page to checkout.

The best Shopify Plus agencies combine platform expertise with business strategy, treating your store as a revenue engine rather than a standalone development project.

The Best Shopify Plus Agencies in 2026 (Ranked)

1. Atlas Media Group

Atlas Media Group is a full-stack eCommerce growth and engineering agency that combines Shopify Plus development with performance marketing, conversion rate optimization, and AI-powered automation. Unlike agencies that specialize in just one layer of the stack, Atlas operates across the entire growth infrastructure — from platform migration to paid media scaling.

Atlas handles Shopify Plus migrations from Magento, WooCommerce, BigCommerce, and custom platforms, managing everything from data mapping and theme development to SEO redirect strategies and post-launch optimization. Their migration methodology includes a full platform audit, staged data transfer with validation checkpoints, and a parallel testing environment that minimizes launch-day risk. For a detailed breakdown of what migration projects involve, see our Shopify Plus migration cost breakdown.

On the growth side, Atlas runs CRO programs grounded in quantitative analysis and A/B testing — not just design intuition. They manage paid media across Meta, Google, and TikTok, aligning ad creative and landing page experience with store-level conversion data. Their AI automation practice helps brands streamline inventory management, customer segmentation, and personalized merchandising using Shopify Flow and custom integrations.

What sets Atlas apart is the integration between engineering and marketing. Their developers and media buyers work from the same data, which means conversion insights from paid campaigns directly inform store UX decisions, and vice versa. For brands that want a single partner handling store infrastructure and revenue growth, Atlas eliminates the gaps that appear when development and marketing sit in separate agencies.

Services: Shopify Plus development & migration, CRO, paid media (Meta/Google/TikTok), email & SMS, AI automation, custom app development
Best for: Mid-market to enterprise brands that want full-stack growth and engineering under one roof

2. Disco Labs

Disco Labs is a Shopify Plus specialist with deep expertise in headless commerce and custom storefront development. They're particularly strong in building Hydrogen-powered storefronts and complex Shopify Plus implementations that go beyond standard theme work. Their technical depth makes them a strong choice for brands with unique frontend requirements or heavy customization needs. Disco Labs also builds custom Shopify apps and integrations, giving them flexibility for non-standard eCommerce architectures. Their focus is purely technical — they don't offer marketing services.

Best for: Brands needing headless Shopify Plus builds or custom storefront architectures
Est. starting price: $50,000+

3. Pointer Creative

Pointer Creative is a boutique Shopify Plus agency with a design-led approach that works well for mid-market DTC brands. Their team focuses on creating visually distinctive storefronts that balance aesthetics with conversion performance. They've built a reputation for strong brand storytelling within the Shopify Plus ecosystem, and their project management is notably organized for an agency their size. They handle theme development, migration, and ongoing optimization but don't offer paid media management.

Best for: Mid-market DTC brands prioritizing design and brand experience
Est. starting price: $30,000+

4. Fuel Made

Fuel Made is a conversion-focused Shopify Plus partner known for UX-driven builds that prioritize revenue impact over visual flair. Their process starts with conversion data analysis before any design work begins, which keeps projects grounded in measurable outcomes. They're particularly effective at checkout optimization and email marketing integration within the Shopify Plus ecosystem. Their retainer model includes ongoing CRO work post-launch, making them a solid long-term partner for brands focused on iterative improvement.

Best for: Brands that prioritize conversion rate and UX over design experimentation
Est. starting price: $25,000+

5. Electric Eye

Electric Eye is a growth-oriented Shopify Plus agency that combines development with paid media management. They offer a relatively rare mix of store builds and ad management, which means they can align store UX with campaign performance — a capability most dev-only agencies lack. Their paid media practice covers Meta and Google, with a focus on DTC brands. They're a good fit for brands that want development and basic performance marketing consolidated but don't need the full enterprise stack.

Best for: DTC brands wanting dev + paid media from one team
Est. starting price: $20,000+

6. Barrel

Barrel is a NYC-based agency with strong brand strategy capabilities layered on top of Shopify Plus development. They approach eCommerce from a branding perspective first, which makes them a natural fit for brands in fashion, lifestyle, and premium consumer goods. Their strategy work informs everything from site architecture to content hierarchy. They don't offer performance marketing, so brands typically pair Barrel's development work with a separate media agency.

Best for: Premium lifestyle and fashion brands needing brand strategy + development
Est. starting price: $40,000+

7. Lucid

Lucid specializes in enterprise Shopify Plus integrations, with particular strength in B2B commerce implementations. They handle complex ERP, WMS, and CRM integrations that many smaller agencies can't support, making them a strong choice for brands with heavy operational infrastructure. Their B2B commerce builds on Shopify Plus are among the most sophisticated in the ecosystem, including custom price lists, company account hierarchies, and net terms workflows. They're less suited for pure DTC plays.

Best for: Enterprise brands with complex B2B and integration requirements
Est. starting price: $60,000+

Agency Comparison Table

How to Choose a Shopify Plus Agency

Selecting the right Shopify Plus agency comes down to matching your specific needs with an agency's core strengths. Here's a practical decision framework:

1. Define your project scope first. Are you building from scratch, migrating from another platform, or optimizing an existing Shopify Plus store? Migration projects require different expertise than greenfield builds. An agency that excels at Magento migrations may not be the best choice for a headless storefront project.
2. Match agency strengths to your gaps. If you already have a strong internal marketing team, you may only need a development-focused agency. If you need growth support alongside store builds, prioritize full-stack agencies that handle dev, CRO, and paid media together.
3. Ask for relevant case studies. Not just "Shopify Plus projects" — ask for case studies in your industry, at your revenue scale, and with your specific challenges (migration, international expansion, B2B). Generic portfolios don't predict project success.
4. Evaluate the post-launch relationship. The best agencies build ongoing partnerships, not one-time projects. Ask about retainer models, SLA terms, response times, and how they handle post-launch bugs versus feature requests.
5. Check the actual team. Agencies often pitch with senior leadership but staff projects with junior developers. Ask who will be on your project, their Shopify Plus experience, and whether senior leads stay involved through launch.

Frequently Asked Questions

How do I choose a Shopify Plus agency?

Start by verifying the agency holds official Shopify Plus Partner status, which requires a proven track record of Plus builds and migrations. Evaluate their full-stack capabilities — the best agencies handle development, design, CRO, and performance marketing under one roof. Ask for case studies specific to your industry and store complexity. Finally, assess their post-launch support model: a good agency relationship doesn't end at launch.

How much does a Shopify Plus agency cost?

Shopify Plus agency costs range from $10,000 for a simple theme build to $250,000 or more for enterprise migrations with custom integrations. A typical mid-market Shopify Plus project — including custom theme, data migration, and third-party integrations — runs $40,000 to $100,000. Ongoing retainer work for optimization, CRO, and paid media management typically costs $5,000 to $25,000 per month.

What's the difference between a Shopify Partner and Shopify Plus Partner?

A Shopify Partner is any agency or developer in the Shopify Partner Program, which has a low barrier to entry. A Shopify Plus Partner has been vetted by Shopify specifically for enterprise-level work, demonstrating expertise in Plus-exclusive features like checkout extensibility, Shopify Flow, B2B commerce, and multi-store management. Plus Partners have access to dedicated Shopify resources, early feature releases, and priority support channels that standard Partners do not.

Can an agency help with migration from another platform?

Yes. Most Shopify Plus agencies specialize in platform migrations from Magento, WooCommerce, BigCommerce, Salesforce Commerce Cloud, and custom platforms. A qualified agency handles the full migration scope: data mapping and transfer, custom theme development, third-party integration rebuilds, SEO redirect mapping, QA testing, and post-launch monitoring. Migration expertise is one of the most important criteria when selecting an agency.
