Top 7 Shopify Plus Ecommerce Agencies & How to Choose the Right Partner
Table of Contents
A Shopify Plus ecommerce agency can be a major asset when your store has outgrown a simple setup. But choosing one isn’t as straightforward as searching for an agency that calls itself a Shopify Plus expert.
I’ll break that down in this guide, along with a shortlist of Shopify Plus agencies, what they may be a good fit for, estimated costs, and how to evaluate them before hiring. Let’s get started!
In this blog:
What Does a Shopify Plus Ecommerce Agency Do?
A Shopify Plus ecommerce agency helps merchants plan, build, migrate, integrate, and continuously improve a Shopify Plus store. The exact scope depends on what your business actually needs, though.
Some agencies are strongest at complex migrations or backend integrations, while others focus more on storefront design, CRO, B2B, or international expansion.
Shopify’s own Partner Directory separates services such as store builds, migrations, systems integration, headless commerce, and ongoing optimization, which is a good reflection of how broad the agency landscape can be.
So, you don't necessarily need an agency that does everything. The better question is which part of your Shopify Plus setup needs expert help right now?
For a typical Plus project, an agency may take responsibility for:
- Strategy and architecture: figuring out what Shopify Plus should handle, what needs customization, and how the store should fit into your wider tech stack.
- Design and development: creating or rebuilding the storefront, custom functionality, and the overall shopping experience.
- Migration: moving products, customers, orders, content, SEO structures, and other critical data from an existing platform.
- Integrations: connecting Shopify Plus with systems such as ERP, OMS, PIM, CRM, payment platforms, and custom applications.
- B2B and international commerce: setting up wholesale workflows, multiple markets, catalogs, pricing structures, and other complex commerce requirements.
- Optimization and support: improving conversion, performance, UX, and functionality after launch rather than treating launch day as the finish line.
The engagement can also look very different depending on the project. A merchant moving from Magento to Shopify Plus may hire an agency for a defined migration project, while a growing brand may keep the same agency on a monthly retainer for development, CRO, and ongoing improvements.
Both models are common across the Shopify ecosystem.
Top Shopify Plus Ecommerce Agencies Worth Considering This Year
So rather than giving you a huge directory, here are seven agencies worth putting on your shortlist, along with where each one appears to fit best.
1. Netalico Commerce
Netalico makes sense if you want a technically strong Shopify Plus partner that can stay involved beyond the initial build. Its current services cover Shopify Plus migrations, UX/UI, custom development, ERP and OMS integrations, CRO, and ongoing support. Netalico also identifies itself as a Shopify Plus Premier Partner.
What stands out is the combination of technical work and ongoing optimization. The agency says it can work on everything from migrations and custom apps to checkout, B2B functionality, performance, and monthly support.
A good fit if: you’re a growing or established DTC brand with a fairly complex Shopify Plus setup and want one team covering development, integrations, and optimization.
2. Xovak Studio
Xovak is worth looking at when the difficult part of your project sits behind the storefront. Its Shopify Plus offering focuses on migration, custom development, B2B and DTC commerce, Checkout Extensibility, Shopify Functions, and integrations with systems such as ERP, CRM, PIM, and OMS.
That makes it particularly relevant if you’re dealing with complicated backend requirements rather than simply looking for a new theme. Xovak also offers custom web and enterprise software development, so its capabilities extend beyond Shopify itself.
A good fit if: your Shopify Plus project involves B2B, complex integrations, custom functionality, or a technically demanding migration.
3. Avex Designs
Avex is a strong candidate if the customer experience and brand side of the project are just as important as the technology. Its Shopify Plus work centers on design, development, migrations, internationalization, systems integration, CRO, and headless commerce.
The agency also has a clear track record in fashion and lifestyle, with Shopify Plus work for brands including KITH, KHAITE, O'Neill, and PSD Underwear.
A good fit if: you’re a fashion, lifestyle, beauty, or other brand-led merchant looking to combine a polished storefront with a larger Shopify Plus transformation.
4. Simplistic
Simplistic is interesting if you want Shopify expertise without adding unnecessary complexity to the project. The agency focuses exclusively on Shopify and Shopify Plus and covers design and development, migrations, ERP integration, CRO, analytics, and ongoing site management.
Its Shopify Partner profile also highlights experience across DTC and B2B, along with industries such as fashion, health and beauty, and jewelry.
I’d pay particular attention to Simplistic if your internal team needs an agency that can build the store and continue helping your team operate and optimize it, rather than treating the launch as the end of the engagement.
A good fit if: you want a Shopify-focused partner for design, development, CRO, migration, and ongoing site management.
5. Swanky
Swanky stands out more when international growth is part of the plan. It works with mid-market and enterprise businesses across the UK, US, Europe, and APAC, with services spanning Shopify Plus development, migrations, integrations, CRO, subscriptions, digital marketing, and internationalization.
Its international Shopify offering is particularly relevant for merchants expanding into new regions, while the agency also has a strong focus on subscription ecommerce.
A good fit if: you’re a mid-market or enterprise brand expanding across markets, especially if internationalization or subscription commerce is part of the growth strategy.
6. Barrel
Barrel is one I’d put higher on the list if you’re a CPG brand. Shopify’s Partner Directory describes Barrel as a commerce agency focused on CPG brands, with services including store builds and redesigns, CRO, strategy, custom apps and integrations, branding, and headless commerce.
The agency has been working with brands on Shopify since 2009 and has been a Shopify Plus partner agency since 2017.
So if your challenge isn't just “build us a Shopify Plus site,” but rather create a stronger DTC experience around the brand, Barrel's positioning is worth considering.
A good fit if: you’re in CPG, food and beverage, health and beauty, or other consumer categories where brand experience and DTC growth are closely connected.
7. DYODE
DYODE takes a broader growth-oriented approach, combining strategy, ecommerce development, and digital marketing. Its current services include Shopify design and development, migrations, CRO/UX, strategy, paid media, email, and SMS.
The agency also positions itself around lifestyle brands and says its team has an operator background, which is reflected in its approach of connecting technology, marketing, and business decisions rather than treating the store as an isolated project.
A good fit if: you’re a lifestyle brand that needs Shopify Plus work to connect closely with CRO, marketing, and broader ecommerce growth.
Which Type of Shopify Plus Agency Do You Actually Need?
The right Shopify Plus agency depends less on how many services it lists and more on what is actually slowing your business down.
That’s the part I’d focus on before contacting agencies.
When You’re Moving to Shopify Plus
Look for an agency with real replatforming experience, not just Shopify development experience.
A migration is more than moving products and customers into a new platform. You also need to think about redirects, SEO, data, integrations, custom functionality, subscriptions, analytics, and how the new store will behave after launch.
I’d also ask how the agency handles the transition itself. A good migration plan should cover testing, redirects, data validation, integration checks, and launch support rather than treating launch day as the finish line.
What to prioritize: Shopify Plus migrations, data migration, SEO preservation, integration planning, and launch support.
When Your Backend Is Complex
Put technical architecture and systems integration near the top of your list.
If Shopify needs to communicate with an ERP, PIM, CRM, OMS, warehouse system, or other internal tools, the storefront is only one part of the project. The bigger question is how customer, product, inventory, order, and pricing data should move between systems.
This is where I’d be careful about hiring an agency simply because it has a strong Shopify portfolio. You want a team that can understand your existing architecture and figure out where Shopify should fit into it.
What to prioritize: ERP and PIM/OMS integrations, API experience, custom development, data flows, and technical architecture.
When You’re Building a B2B Store
Choose an agency that understands B2B workflows, not one that simply knows how to build a Shopify storefront.
B2B can introduce requirements that aren't typical in a DTC store, such as company accounts, customer-specific pricing, catalogs, payment terms, and different purchasing workflows. Shopify currently supports native B2B functionality on Shopify Plus, but the way those features need to work with your existing processes can still get complicated.
The agency should understand how your sales, operations, and customer teams actually work, then translate those requirements into the Shopify setup.
What to prioritize: Shopify Plus B2B experience, wholesale workflows, custom pricing and catalogs, ERP integration, and account management.
When You’re Expanding Into New Markets
Look for an agency that has handled multi-market Shopify stores, rather than treating international expansion as a simple translation project.
Selling in another country can affect currencies, domains, pricing, taxes, payments, shipping, product availability, and the overall shopping experience. Shopify Markets can help merchants manage multiple markets from Shopify, but your agency still needs to understand how those markets fit into the wider business.
What to prioritize: Shopify Markets experience, localization, international payments, multi-market architecture, and regional UX.
When Conversion and Growth Are the Priority
Don’t automatically hire a development-heavy agency if your real problem is that the store isn’t converting.
If your Shopify Plus store is already technically solid, rebuilding everything may not be the best use of your budget. You may get more value from an agency that can identify friction in the customer journey, improve merchandising, run CRO work, and use analytics to guide changes.
What to prioritize: CRO, UX, analytics, experimentation, merchandising, and ongoing optimization.
When You’re Considering Headless Commerce
Make sure you actually have a reason to go headless before choosing a headless specialist.
Headless can make sense when you have more demanding content or experience requirements, need greater control over the frontend, or have a broader commerce architecture that benefits from separating the storefront from the commerce backend. Shopify supports headless commerce through its APIs and Hydrogen framework.
But headless also introduces another layer of development and maintenance. So I wouldn’t choose an agency simply because it can build a headless Shopify store. I’d first ask whether headless solves a problem you actually have.
If the answer is yes, then look for an agency with proven experience designing and maintaining that type of architecture.
What to prioritize: Hydrogen, headless architecture, API development, frontend performance, and long-term maintenance.
How Much Does a Shopify Plus Agency Cost?
There’s no fixed price for hiring a Shopify Plus agency. As a rough market estimate, you can expect to spend around $30,000-$500,000+ for a custom Shopify Plus build or major migration.
More complex projects, such as headless builds, multi-store setups, or extensive backend integrations, can go beyond these ranges.
Estimated Shopify Plus Agency Costs
Project type | Estimated cost | Typical scope |
|---|---|---|
Theme refresh / optimization | $30,000-50,000+ | Major storefront, UX, performance, and customization work |
Standard Plus build or replatform | $50,000-100,000 | Custom storefront, migration, core integrations, QA, and launch |
Advanced Plus build with integrations | $100,000-250,000+ | Complex ERP/PIM/OMS integrations, B2B, multi-market, or custom functionality |
Headless / enterprise architecture | $150,000-500,000+ | Custom frontend architecture, complex integrations, and multi-store or multi-region setups |
Estimated Ongoing Agency Retainers
If you want an agency to stay involved after launch, a reasonable estimated range is around 5,000-20,000+ per month. The actual retainer depends on how much development, CRO, design, strategy, and technical support you need.
- 5,000-8,000/month: Lighter ongoing development, maintenance, bug fixes, and smaller improvements.
- 8,000-15,000/month: Regular development combined with CRO, design, analytics, and ongoing optimization.
- $20,000+/month: More dedicated support for complex integrations, multiple workstreams, or enterprise-level requirements.
These numbers are estimates, not standard Shopify Plus pricing. Agency fees vary significantly depending on the scope of work, technical complexity, number of integrations, and how much ongoing support you need. So I’d use the ranges above to set a realistic budget, not as a benchmark you should expect every agency to quote.
Final Thoughts
Finding the right Shopify Plus ecommerce agency starts with knowing what you actually need help with.
Look for an agency that has handled projects similar to yours, be clear about who will actually work on your store, and make sure the scope, pricing, and post-launch support are defined before you sign.
But choosing the agency is only one part of the equation. Once your Shopify Plus store is live, you also need to know whether the investment is translating into a healthier business.
At enterprise scale, revenue alone tells you very little. What matters is turning reliable data into strategic decisions, and growing on profit-driven insights that once felt out of reach.
