Best Shopify Agencies in the US, Compared by Budget and Specialty

Most "best agency" lists rank firms on one flat scale, which tells a buyer little. A $4 million apparel brand replatforming from Magento and a new store that needs a theme fix are shopping in different markets. This guide sorts agencies on two questions instead:

• Budget tier: what is the published starting point for a project or a month of support?

• Specialty: is the firm a fit for a new build, a migration, ongoing support, or all three?

The list covers agencies that serve US brands, and that is a wider group than agencies headquartered in the US. Each entry says where the firm is based, including when that is outside the country, so buyers can weigh time zones and contract terms themselves. Figures for the three other agencies come from their own websites or their Clutch profiles, as checked in November 2026. They are starting points, and a written quote will differ.

1. Netalico: best for one team across build, migration and support

Based in: the Americas, from hubs in New York, Los Angeles, San Francisco and Miami, with more colleagues in Canada and Brazil

Founded: 2011, and full-time since Mark Lewis, its founder, left NASA in 2013

Who it fits: DTC merchants doing $2M to $50M GMV

Netalico is a Shopify agency and a Shopify Plus Premier Partner, with Shopify Partner status dating to 2016 and hundreds of Shopify builds behind it. Every person is in-house and on US hours, and no work goes to subcontractors. Its public profile shows 4.9 out of 5 on Clutch. Outside client projects, Lewis serves several larger brands as their fractional ecommerce and Shopify CTO. He is also the lead expert in Shopify's enterprise guide on using AI for ecommerce migration.

The case for ranking it first rests on continuity, and the project record shows it:

• Build and migration: Big Green Egg consolidated separate BigCommerce and WordPress sites into one Shopify Plus store on a 12-week timeline, with an initial launch scoped first and later phases planned after it. A buyer shopping for as development company to run a phased replatform like that gets design and engineering under one contract.

• Migration, then long-term care: Crossrope moved from BigCommerce to Shopify Plus in three months, launched in May 2020, added a global rollout through Global-E a few months later, and stayed on with the same agency for further work.

• Complex catalogs: Limitless Walls has worked with Netalico since 2016, first on Magento 1 and then through a 2022 move to Shopify Plus. Its image library runs into the millions, with products created on demand and priced by the square inch.

• Retainer results: Oatly's US team has used Netalico as its Shopify development team since 2019. After improvements to its Recharge subscription signup and account screens, Oatly saw a 188% increase in monthly recurring revenue from subscriptions in three months.

Budget: projects run $25,000 to $250,000+. Monthly fees for Shopify maintenance and support fall between $2,700 and $10,000, and the average client pays around $4,500.

Who should look elsewhere: a store under about $2M GMV, or a buyer who needs a single small fix, will probably be better served in the tiers below.

2. CSSChopper: best for theme work and dedicated Shopify developers

Based in: New York, with other locations in London, Noida and Abu Dhabi

Founded: 2009

Who it fits: brands that already have a design to implement, or that want to hire Shopify developers by the hour, week or month

CSSChopper's Shopify page names theme customization, PSD to Shopify, Shopify Plus services, migration, and support and maintenance. Buyers can take a time-based model or onboard several dedicated developers with an assigned project manager. Clutch lists a $10,000 project minimum and $25 to $49 an hour, and it puts Shopify at 30% of the firm's ecommerce systems focus. The page publishes no package prices, so scope and cost come through a quote.

3. Mageplaza: best for a Magento to Shopify data move

Based in: Hanoi, Vietnam, with an office in New York

Founded: 2014

Who it fits: Magento merchants with a clear migration scope and an in-house owner for design and post-launch changes

Mageplaza's migration service covers products, customers, orders, content pages, store settings, meta data and 301 redirect rules, followed by post-launch monitoring and staff training. Pricing is advertised as starting from $99, and it rises with data volume and customization. Clutch lists a $1,000 project minimum and $25 to $49 an hour, with an ecommerce mix of 70% Magento and 25% Shopify.

Based in: Noida, India, with further offices in London, Dubai and the US

Founded: 2004

Who it fits: brands with a technical lead who can direct outside developers

ValueCoders is a broad software firm, and Shopify is one of several ecommerce platforms on its service page. Its staff augmentation model adds one to three engineers to a client's team, billed on time and materials or on retainer, and its dedicated pods run four to ten people. Clutch lists a $1,000 project minimum and a rate under $25 an hour.

The bands below come from the figures published by the agencies above, so they show real price points and do not amount to a market survey.

• Data-only migration: from $99 at Mageplaza's advertised entry point, with the final price set by catalog size and customizations. Design, apps and integrations sit outside a basic move, so budget for them separately.

• Smaller project with an outside team: published minimums start at $1,000 for Mageplaza and ValueCoders and at $10,000 for CSSChopper.

• Mid-market build or replatform with integrations: $25,000 to $250,000+ at Netalico. Catalog size, custom features and the number of connected systems move the figure.

• Monthly support on a named team: Netalico's retainers span $2,700 to $10,000, with an average near $4,500.

• Hourly capacity: under $25 an hour on Clutch for ValueCoders, and $25 to $49 for CSSChopper and Mageplaza.

Identical monthly spend can buy very different things. Before comparing two quotes, ask who is on the account, whether those people built the store, and what happens when an urgent bug lands outside the agreed hours.

1. How much does a Shopify agency cost for a US brand?

Published starting points in this comparison range from $1,000 for a small project to $25,000 for a mid-market engagement, and full replatforms can pass $250,000. Netalico's retainers run $2,700 to $10,000 a month, while CSSChopper and ValueCoders can bill ongoing developer time on a time-and-materials basis.

2. Which Shopify agency is best for a migration?

It depends on what is moving. For a replatform with custom features, integrations and a redesign, Netalico leads this comparison, with Big Green Egg, Crossrope and Limitless Walls as documented examples. For a contained Magento data move, Mageplaza has a service built around that job.

3. How long does a Shopify migration take?

Big Green Egg's initial launch ran on a 12-week timeline, and Crossrope's migration took three months. Mageplaza quotes a few weeks to a couple of months for its data-focused service, and store complexity sets where a project lands.

4. Does a Shopify agency need to be based in the US?

No, but working hours matter. Netalico's team overlaps the US business day, CSSChopper is headquartered in New York with a location in Noida, and Mageplaza and ValueCoders are headquartered in Asia. Ask any vendor how many hours overlap with your team and who is reachable during a launch.

5. Should the same team handle the build and the retainer?

If the store carries meaningful revenue, usually yes. A team that wrote the code does not have to relearn it before fixing it, and its launch decisions stay accountable after launch. Smaller stores with few customizations can reasonably split the two to save money.

6When is a lower-cost agency the better choice?

When the scope is tight, the requirements are written down, and someone in-house can review the work. A clear brief and a technical owner make the tier two and tier three options above practical for many brands.
