Top 10 eCommerce Migration Agencies in the US

Replatforming your eCommerce store is one of the highest-stakes decisions you will make as a business leader. Done well, it unlocks faster performance, lower operational costs, and a scalable foundation for growth. Done poorly, it can cost you months of lost revenue, SEO rankings that took years to build, and customer trust that is nearly impossible to recover.

The scale of platform movement underscores just how active this market has become. In a recent 90-day period alone, over 21,800 stores migrated to Shopify, nearly double the number that left, making it the most popular migration destination in US eCommerce (Shopify, 2025). Meanwhile, Magento remains the platform merchants are most frequently leaving, and Shopify’s total cost of ownership runs on average 29% lower than Magento’s, according to comparative platform analysis. The business case for migration has never been stronger, but the execution risk has never been higher either.

Choosing the right migration agency is therefore not a procurement decision; it is a strategic one. This guide profiles the 10 most capable eCommerce migration agencies operating in the US today, examines what makes each distinct, and concludes with a practical framework for selecting the right partner for your specific situation.

Why eCommerce Platform Migration Is a High-Stakes Decision

Most merchants underestimate the complexity of a platform migration until they are already in the middle of one. A migration is not just a data transfer; it involves rebuilding your storefront architecture, remapping hundreds or thousands of URLs, preserving SEO equity, recreating custom functionality, integrating your existing tech stack, and training your team on a new system, all while keeping your store live and your customers unaffected.

The agencies listed here have demonstrated the ability to manage that complexity at scale. Each has been selected based on platform certifications, documented migration methodology, client outcomes, and depth of US-based operations.

Agency Comparison at a Glance

How to Choose the Right eCommerce Migration Agency

Every agency on this list is capable of executing a technically sound migration. The difference between a good outcome and a great one comes down to fit — how closely the agency’s methodology, communication style, and post-migration capabilities align with your specific business needs.

Here are the six questions that should drive your selection process:

1. What is their documented migration methodology?

Ask any agency to walk you through their specific process step by step. Vague answers like ‘we follow best practices’ are a red flag. The best agencies have a named framework, clear project phases, defined deliverables at each stage, and a documented quality assurance process before launch. If they cannot articulate it, they are improvising.

2. How do they handle SEO preservation?

URL structure, redirect mapping, metadata, schema markup, Core Web Vitals — these are all migration risks that can quietly destroy months of organic ranking if not handled with precision. Ask to see their SEO migration checklist and whether they conduct a pre- and post-migration audit. For any business where organic search drives meaningful revenue, this is non-negotiable.

3. What does post-launch support look like?

Many agencies consider a migration complete when the new store goes live. The best agencies know that the 30 to 60 days after launch are when the real issues surface. Ask specifically: what is included in post-launch support, for how long, and what is the SLA for response time on critical issues?

4. Do they have case studies from businesses like yours?

A successful migration for a $5M fashion DTC brand looks very different from one for a $100M B2B distributor with ERP integrations. Ask for case studies that match your revenue range, platform type, catalog size, and complexity. A track record with similar businesses is the strongest predictor of a smooth project.

5. Who will actually work on your project?

Agencies win business with senior people and deliver it with junior ones. Ask directly who will be your project manager, who will handle your data migration, and who will be responsible for QA. Get their names and experience levels in the proposal. The quality of the people on your project matters more than the agency’s brand name.

6. How do they price, and what is not included?

Migration projects are notorious for scope creep. A low initial quote can balloon significantly when custom feature recreation, additional integrations, or extended testing are factored in. Ask for a fully itemized quote that specifies exactly what is in scope, what triggers an additional cost, and what post-launch activities are included. Transparent pricing at the start is one of the clearest signals of a trustworthy partner.

Red Flags to Watch For

Before signing with any migration agency, watch for these warning signs:

• Unrealistically fast timelines. Complex migrations take time. An agency promising an enterprise-level migration in two to three weeks is either cutting corners or does not understand the scope.
• No mention of SEO in their process. Any migration partner who does not proactively raise the issue of SEO preservation has not given the risks sufficient thought.
•  Lack of platform certifications. Official Shopify Plus Partner, Adobe Commerce (Magento) certification, and BigCommerce Partner status exist for a reason — they signal that an agency has met the platform’s own standards for competency.
• Unclear post-launch support terms. If the agency goes quiet after launch, you are on your own at the most critical moment of the project.
• No client references available. Any agency worth working with should be able to provide direct client contacts who have completed similar migrations.

Signs It Is Time to Replatform

If you are still weighing whether to migrate at all, the following are the most common indicators that your current platform is actively holding your business back:

• Your development team spends more time on maintenance and workarounds than on features that drive growth.
• Your site speed scores are consistently poor, and your current platform limits your ability to improve them.
• You are paying for hosting, security patches, and custom development that would be handled natively on a modern platform.
• Your checkout process has friction points that your current platform cannot resolve without expensive custom development.
•  Integrating new marketing tools, apps, or channels requires significant development effort every time.
•  Your team finds the day-to-day management of the platform slow, unintuitive, or frustrating.

Final Thoughts

The right migration agency doesn’t just move your store—they set it up to grow. The best outcomes come when you choose a partner whose methodology is rigorous, whose communication is transparent, and whose capabilities extend beyond launch day into the ongoing performance of your new platform.

The ten agencies profiled here represent the strongest options in the US market across different specializations, business sizes, and platform combinations. Use the selection framework above to narrow your shortlist, ask the right questions, and choose the partner that aligns most closely with your specific situation.

A well-executed migration is one of the highest-ROI investments an eCommerce business can make. Take the time to get the partnership right.

Frequently Asked Questions About eCommerce Migration

How much does an eCommerce platform migration cost?

Migration costs vary significantly based on platform complexity, catalog size, and the level of customization required. For a straightforward WooCommerce-to-Shopify migration with a clean data set, expect to invest between $5,000 and $15,000. Mid-market migrations involving Magento, complex integrations, and the recreation of custom features typically range from $25,000 to $80,000. Enterprise-level projects with ERP systems, large SKU counts, and bespoke functionality can run $100,000 or more. Always ask agencies for a fully itemized quote — scope creep is the single biggest driver of budget overruns in migration projects.

How long does a platform migration take?

The timeline depends on the complexity of your current store. A lean WooCommerce-to-Shopify migration can be completed in four to eight weeks. A mid-market Magento migration typically takes three to five months when done properly, accounting for data mapping, recreating custom features, SEO setup, QA, and a staged launch process. Any agency quoting less than 4 weeks for a complex migration is either skipping critical steps or underestimating the scope. Build in a buffer of at least 4 weeks for post-launch stabilization before declaring the project complete.

Will I lose SEO rankings when I migrate platforms?

SEO loss is the most common and most preventable risk in platform migration. It happens when URL structures change without proper 301 redirects, metadata is not carried over, internal linking breaks, or site speed degrades on the new platform. A competent migration agency will conduct a full SEO audit before migration, map every URL to its redirect destination, preserve all metadata and structured data, verify Core Web Vitals performance on the new stack, and monitor search console data in the weeks following launch. Ask any agency shortlisted for your project to show you their specific SEO migration checklist before signing.

Should I migrate myself or hire an agency?

DIY migration tools such as Cart2Cart, LitExtension, and Matrixify can handle data transfer for small stores with simple structures. If your store has fewer than 500 SKUs, minimal customization, no complex integrations, and limited organic search traffic, a tool-assisted self-migration is a reasonable option. However, if your store generates meaningful revenue, has significant organic traffic, relies on custom functionality, or has complex tech stack integrations, the risk of a DIY migration far outweighs the cost savings. A failed migration — including lost SEO equity, data errors, or prolonged downtime — will typically cost more to remediate than a properly scoped agency engagement would have cost upfront.
