Scaling an eCommerce business to enterprise levels means outgrowing the capabilities of a basic Shopify store. As businesses expand, they often need more advanced features, from greater customization to automation and scalability. This is where Shopify Plus comes in - offering more flexibility, higher performance, and tools designed for high-growth brands.
However, upgrading to Shopify Plus isn't just about unlocking new features. The transition itself comes with its own set of challenges - from data migration and complex integrations to ensuring seamless operations across multiple regions. Navigating these complexities requires expertise, which is why many leading brands turn to specialized Shopify Plus agencies to make the process smooth, efficient, and risk-free. These agencies offer the strategic guidance and technical prowess needed to transform your vision into a high-performing, revenue-generating reality.
In this guide, we’ve handpicked 10 top Shopify Plus agencies, highlighting their expertise, standout services, and success stories. Whether you need seamless integrations, high-converting designs, or strategic growth solutions, this list makes it easier to find the perfect eCommerce partner to scale, optimize, and thrive.
Let’s check it out!
1. Why do businesses need Shopify Plus agencies?
As eCommerce businesses grow, so do their demands - whether it's expanding product lines, entering global markets, or scaling operations with a larger team. To keep up, many brands find themselves needing a more powerful platform.
Shopify Plus, the enterprise-level solution of Shopify, provides the scalability, advanced features, and automation capabilities essential for high-growth businesses looking to upgrade from lower-tier Shopify plans or migrate from other platforms.
However, as businesses scale, they can’t afford to spend excessive time navigating a platform transition or risk costly missteps due to inexperience.
That’s where Shopify Plus agencies come in.
These experts not only streamline the migration or upgrade process but also minimize risks, accelerate implementation, and provide strategic guidance - ensuring brands make the most of Shopify Plus from day one.
So, when exactly do businesses need a Shopify Plus agency?
While Shopify Plus offers powerful features, leveraging its full potential often requires more than just the platform itself. Brands turn to Shopify Plus agencies when they face challenges such as:
- Lack of in-house expertise: In-house teams may not have the technical knowledge to manage complex Shopify Plus functionalities.
- Heavy customization needs: Businesses that require tailored storefronts, unique checkout experiences, or advanced automation.
- Migrating from other platforms: Transitioning from Magento, WooCommerce, or custom-built solutions requires careful execution to avoid data loss or downtime.
- Scaling operations globally: Expanding into new markets means handling multi-currency, multi-language support, and localized payment integrations.
- Ongoing optimization & strategy: From improving conversion rates to implementing data-driven growth strategies, agencies provide continuous improvements beyond the initial setup.
Whether you're upgrading from a lower-tier Shopify plan, migrating from another platform, or are already on Shopify Plus but looking to optimize operations and maximize revenue, Shopify Plus agencies can ensure a smooth transition and sustainable growth. Now, we’ll break down the key benefits these agencies bring to the table.
1.1. Handling complex platform migration with minimal risk
Many enterprise-level businesses shift from platforms like Magento, WooCommerce, or Salesforce Commerce Cloud to Shopify Plus due to its scalability and ease of use.
However, migration is a complex process that involves data transfer, design adjustments, and system integrations. Without professional assistance, businesses risk downtime, data loss, or performance issues. Shopify Plus agencies ensure a smooth transition while minimizing disruptions.

1.2. Overcoming internal technical constraints
While internal teams may handle day-to-day operations well, Shopify Plus implementations require specialized knowledge. Advanced customization, theme development, and performance optimization demand experienced Shopify Plus developers who understand the nuances of the platform.
Beyond technical implementation, agencies bring strategic value by offering access to industry best practices. Having worked with various businesses across different industries, they provide insights, benchmarks, and proven strategies to help brands optimize their eCommerce operations and stay ahead of the competition.
1.3. Managing enterprise-level system integrations
One of the biggest advantages of partnering with Shopify Plus agencies is their ability to handle complex integrations.
Enterprise businesses rely on various tools and platforms for managing customer relationships, inventory, and data analytics. A Shopify Plus agency ensures seamless integration with enterprise resource planning (ERP), customer relationship management (CRM), and data analytics tools, creating a unified system that enhances operational efficiency.
1.4. Building customized checkout solutions
Customization is another crucial factor.
Unlike standard Shopify stores, enterprise-level businesses often require tailored solutions, especially when it comes to checkout processes. Whether it’s implementing custom pricing rules, subscription-based models, or multi-step checkouts, Shopify Plus agencies can develop personalized solutions to enhance user experience and conversion rates.
1.5. Implementing advanced automation for efficiency
Automation is a key selling point of Shopify Plus, but to truly harness its power, businesses need expert guidance.
Shopify Plus agencies help set up advanced automation workflows, reducing manual tasks and streamlining operations. From automated order processing to AI-driven marketing campaigns, they enable businesses to scale more efficiently.
1.6. Managing multi-channel and multi-store operations
As businesses expand into multiple sales channels - whether marketplaces, social media platforms, or brick-and-mortar stores - managing everything from a single dashboard becomes challenging.
Shopify Plus agencies specialize in multi-channel commerce integration, ensuring that inventory, pricing, and order fulfillment remain synchronized across various platforms.
1.7. Ensuring enterprise-level security and compliance
Security is a top concern for enterprise businesses handling high volumes of transactions.
Shopify Plus already provides robust security measures, but agencies help reinforce these protections by implementing additional security layers, such as fraud prevention tools, advanced access controls, and PCI compliance optimization.
1.8. Supporting international expansion
For brands aiming for global expansion, Shopify Plus agencies provide invaluable support. Selling in multiple regions means handling different currencies, tax regulations, and localization requirements. Agencies assist in setting up multi-store management, ensuring a seamless shopping experience for international customers.
1.9. Providing dedicated support and maintenance
Ongoing support and maintenance are often overlooked but are critical for sustained growth. Shopify Plus agencies offer continuous monitoring, troubleshooting, and performance optimization, ensuring that online stores run smoothly.
Whether it's rolling out new features, upgrading infrastructure, or resolving unexpected issues, businesses benefit from dedicated expert support.
In conclusion, Shopify Plus is a powerful platform for scaling eCommerce businesses, but leveraging its full potential requires expertise. Choosing the right agency is crucial to ensuring a smooth transition and long-term success.
In the next section, we'll explore the key criteria to consider when selecting a Shopify Plus agency to find the best fit for your business needs. Let’s dive in!
2. How to choose the right Shopify Plus agency?
Every big brand began with a small inventory. The first steps are always difficult, but with the right Shopify agency, your journey can be much smoother. With numerous options of Shopify Plus agencies available, understanding what criteria to consider will help you make the best decision.
Here’s what you need to look for when choosing an agency.
2.1. Technical expertise and certification
A strong technical foundation is essential. You should look for agencies that are verified Shopify Plus partners or have relevant certifications.
Shopify Plus Partners are selected for their technical expertise in supporting high-growth businesses. They have access to specialized tools, advanced API resources, and structured tiers (Registered, Select, Plus, Premier, and Platinum) that reflect their level of expertise.
You should look for:
- Verified Shopify Plus partner status (Premier or Platinum tier preferred).
- Experience working with Shopify Scripts (for custom discounts, shipping logic, etc.).
- Expertise in Shopify Flow (automating tasks like order tagging, inventory updates, and fraud detection).
- Proficiency in Checkout Extensibility (creating a highly customized checkout experience, exclusive to Shopify Plus).
2.2. Industry experience & portfolio
Experience matters, and you’ll want a Shopify plus development agency that has relevant experience in your industry vertical. It is essential to review their portfolio for case studies that showcase measurable results and successful projects. An agency with an enterprise-level client portfolio demonstrates its ability to manage large-scale operations effectively.
Practical tips:
Request specific case studies that align with your business model. If you’re expanding from the U.S. to Europe, your agency should help you implement VAT adjustments, localized payment gateways, and region-specific pricing strategies.
2.3. Service scope & capabilities
Your business has unique needs, and the Shopify Plus agencies you choose should offer services that match them. You need to consider:
- Expertise in headless commerce (using Shopify Plus with a custom frontend like React.js for lightning-fast performance).
- Advanced B2B and wholesale solutions (custom pricing, bulk order automation, customer-specific catalogs).
- Shopify Plus-exclusive API integrations (for customized workflows and data synchronization).
2.4. Communication and project management
Clear and effective communication can make or break a project. Ensure that these Shopify Plus agencies have:
- Quick response time and availability to address urgent matters.
- Transparent reporting processes so you always know the project’s progress, including weekly or biweekly check-ins.
- Crisis management procedures to handle unexpected challenges efficiently, like downtime or security breaches.
2.5. Long-term support and maintenance
A good Shopify Plus agency doesn’t just build your store - it provides long-term support to ensure continued success. Whether it's post-migration assistance or ongoing optimization, a reliable agency helps businesses adapt and grow. It should include:
- Post-migration support to ensure smooth operations after launching on Shopify Plus, addressing any unforeseen issues.
- Bug fixes and emergency support (e.g., website downtime resolution within 2 hours).
- Peak season readiness (for handling massive Shopify Black Friday & Cyber Monday sales).
- Feature updates like adding new payment gateways as Shopify releases new functionalities.
By partnering with Shopify Plus agencies for long-term support, you can stay ahead of platform changes, minimize disruptions, and continuously optimize your store’s performance.
2.6. Cost and value assessment
Understanding pricing models is key when selecting a Shopify Plus agency. You need to take flat-rate pricing vs. hourly rates into consideration. Flat rates work best for well-defined projects with clear deliverables, while hourly rates offer flexibility for ongoing support and iterative improvements.
Also, you should request a detailed breakdown of costs, including potential additional charges for extra features, revisions, or extended timelines.
2.7. Security and compliance
Security should never be an afterthought. Shopify Plus supports SOC 2 compliance and custom fraud prevention - your agency should have expertise in securing high-revenue stores.
Shopify Plus agencies should implement IP whitelisting, advanced fraud detection, and PCI DSS compliance for secure payments.
In short, when selecting a Shopify Plus agency, keep these key criteria in mind:
- Technical expertise & certification: Look for Shopify Plus Partner status (preferably Premier or Platinum)
- Industry experience & portfolio: Choose an agency with proven results in your industry and successful case studies.
- Service scope & capabilities: Ensure they offer services tailored to your needs.
- Communication & project management: Opt for agencies with clear communication channels, structured project management, and fast response times.
- Support & maintenance: Prioritize agencies that provide ongoing support, emergency fixes, and peak season readiness.
- Cost & value assessment: Focus on ROI-driven services and request a detailed cost breakdown.
- Security & compliance: Make sure they have expertise in fraud prevention, PCI DSS compliance, and store security.
Choosing the right Shopify Plus agency isn’t just about finding a Shopify expert - it's about finding a partner that understands the complexities of your high-growth, enterprise-level business.
Now that you know what to look for in an agency, let’s dive into some of the best Shopify Plus agencies that can help take your business to the next level.
