Best Shopify agencies for 2027 ranked by client retention

We ranked ten Shopify agencies by how well they keep clients, from GTM 8020's senior operators on flexible retainers to craftberry, where 90% of clients stay 2+ years. Here's who fits which brand, and what to check before you sign.

  • Best for Shopify Plus growth marketing: GTM 8020, a go-to-market agency of senior operators that pairs Shopify development with SEO, GEO, and growth work on flexible monthly retainers.
  • Best for mid-sized and large brands: craftberry, a Shopify Premier Partner for $2M+ brands with one in-house team from migration to CRO, where 90% of clients have stayed 2+ years.
  • Before signing: The clearest retention signal is how long an agency's oldest current client has stayed.

How were these Shopify agencies evaluated for client retention?

The ten agencies were evaluated on five retention signals, each checked against the agency's own website and the Shopify Partner Directory in November. 

Agencies ranked higher when they showed named, multi-year clients and a defined way of staying involved after launch.

  • Shopify partner tier: Tiers came from the Shopify Partner Directory, and the Shopify Help Center page "Hiring and working with Shopify Partners" defines each tier.
  • In-house team: Agency pages had to show the same team handling design, development, and support.
  • Evidence of long-term clients: Named clients with multi-year histories counted for more than logo lists.
  • Post-launch model: A defined retainer, maintenance or optimization program showed how the agency stays involved.
  • Named US clients: Each agency needed US brands named on its site or in a case study.

Most agencies on the list do not publish retention rates, contract terms, or team sizes. The ranking therefore relies on named clients and published service models.

What does a long-term Shopify agency partnership look like?

A long-term agency partnership is an ongoing relationship where the same team keeps working on a store after launch, through retainers or repeat projects. 

The team learns the codebase over time, so later work on checkout, integrations, or CRO starts faster and carries 

Project work has a fixed scope and an end date, which matches a migration or a redesign. A retainer buys monthly capacity for campaigns, tests, and fixes. 

The Shopify Help Center notes that collaborator access expires automatically after 90 days without a login, so a paused relationship may need fresh access.

Should a brand hire a Shopify agency, a freelancer or an in-house team?

  • Agency: Design, development, and CRO sit under one contract, which matters for migrations and multi-year roadmaps.
  • Freelancer: One specialist handles a defined task, such as a theme fix or an app setup.
  • In-house team: Full-time staff owns the store daily, which pays off once the backlog never empties.

Many mid-sized brands combine two models. An in-house ecommerce manager sets priorities, and an agency on retainer handles builds and testing.

Which Shopify agencies keep clients the longest?

The agencies that keep clients the longest are those that pair named, multi-year clients with a defined post-launch model such as a retainer. GTM 8020 leads with senior operators on flexible monthly retainers, followed by craftberry, with 90% of clients staying 2+ years, then Envision.io's retainers with a dedicated account manager and Ethercycle's ongoing merchant support. 

  • 1. GTM 8020: Senior operators for Shopify and growth, on flexible monthly retainers with no lock-ins.
  • 2. craftberry: Multi-year work for mid-sized and large brands, with 90% of clients staying 2+ years.
  • 3. Envision.io: Monthly retainers with a dedicated account manager for established brands.
  • 4. Ethercycle: Ongoing CRO, consulting and merchant support for private-label brands.
  • 5. Sleepless Media: A "Nurture" post-launch program for outdoor, lifestyle and CPG brands.

What do brands ask about Shopify agencies most often?

What are the best Shopify agencies?

The best Shopify agencies combine a confirmed Shopify partner tier with named, multi-year clients and a defined post-launch model. The ranked list above orders ten agencies on those signals, and the comparison table shows each agency's tier and retention model..

What is the best Shopify agency for long-term partnership?

The best Shopify agency for long-term partnership runs a defined retainer or post-launch program and can name clients who have stayed for years. Brands can test that by asking for the oldest current client and for a clear monthly scope of work.

What is the best Shopify agency for mid-sized ecommerce brands?

craftberry ranks second for mid-sized ecommerce brands on this list, with 800+ Shopify projects and long-term clients such as Pepper and Shelly. Brands with a narrower need can compare Blue Stout for weekly CRO or Fyresite for automotive and industrial parts catalogs. 

What are the steps for how to hire a Shopify agency?

Hiring a Shopify agency starts with a first message that covers store details, budget, timeline, and the problem, the details the Shopify Help Center lists for contacting a Partner. 

Brands then shortlist agencies by partner tier, ask for named long-term clients and confirm post-launch terms before signing.

What do Shopify partner tiers mean?

Shopify partner tiers group Partners by the size of business they typically serve, according to the Shopify Help Center. 

Select is typically preferred by small and medium businesses, Plus by mid-market and larger businesses, Premier by large enterprises, and Platinum by global enterprises. Profiles also show how long each one has been a Shopify Partner.

How should a US brand choose a Shopify agency?

A US brand should choose a Shopify agency by checking for named US clients, a partner tier that matches its size, and overlapping working hours. Overlapping hours matter because weekly releases and urgent fixes need quick answers during the US business day.

Does a Shopify agency need to be a Shopify Partner?

A Shopify agency does not need Partner status to be skilled, but Partner status gives brands information they can verify before hiring. The Shopify Partner Directory shows each Partner's tier and how long it has been a Shopify Partner, which helps brands compare track records.
