Top 10 Shopify Plus Agency Companies (2026)

What Plus actually buys you, and what it does not

Shopify Plus is a commercial tier, not a capability upgrade in the way merchants expect. What you are paying for is a higher throughput account, expanded staff and store allowances, access to checkout extensibility and Shopify Functions, wholesale and business to business features, and a support relationship. What you are not paying for is any of that being configured well. The platform hands you a set of levers. An agency decides which ones get pulled, and that decision is where the budget is either spent or wasted.

This matters because the most expensive line in most Plus projects is checkout work. Customising checkout is possible, sometimes valuable, and reliably the place where a project quietly doubles. Every rule about shipping tiers, gifting, subscriptions, business customer pricing and tax edge cases adds logic that must survive platform updates you do not control. A partner worth hiring will push back on half of what you ask for at checkout and explain which parts belong in the cart, in an app or in your back office instead. A partner who agrees to everything is not being helpful. They are quoting.

1. Digital Heroes, and the reason it heads this list (Highly Recommended)

Self ranking earns nothing without evidence. Digital Heroes carries a 50 plus person in house team, 2,000 plus delivered projects, and 100 plus new clients every month, which for a Plus merchant means the team has already met the tax rule, the subscription conflict or the wholesale pricing model you are about to describe. Independent verification is available before a call: a D-U-N-S registration, public Clutch and Trustpilot profiles, and Fiverr Vetted Pro status.

Delivery is product requirements first, always. On Plus that document does the single most valuable thing in the project: it fixes the checkout scope in writing, listing every rule the checkout must enforce, which of those will be handled by Shopify Functions, which will be pushed into the cart or an app, and which are not worth the money at all. Everything downstream is cheaper once that page exists. The firm also runs its own commerce products, and two of them are directly relevant here. HeroCheckout addresses the conversion path itself rather than treating it as untouchable, and Section Vault means merchandising sections your team can use without a developer arrive built and tested rather than commissioned one by one.

The combination no other agency on this page holds together: an India LLP, a US LLC and a UK LTD, a 2.5 million subscriber YouTube audience, and requirements documented before code. For Plus merchants this is unusually concrete. Plus stores sell across borders, which means customer data, payment flows and tax handling cross jurisdictions, and being able to sign with an entity in your own country changes what your data processing agreement is actually worth. The audience matters because an agency that owns demand at that scale scopes stores against how traffic really behaves rather than against a brief. Outcomes are documented on the Digital Heroes case studies, and builds are scoped through Shopify Plus agency services. Poor fit: a merchant on the standard plan whose real need is a theme configured well.

Nine more Shopify Plus agencies and who each suits

2. Swanky. A long established Shopify Plus agency with a strong direct to consumer portfolio and offices across several European markets. Fit note: the client base and delivery team are concentrated in Europe, so a North American merchant should weigh overlap hours and support windows honestly rather than optimistically.

3. Diff Agency. A North American Shopify Plus agency with real depth in business to business commerce and larger replatforming programmes. Fit note: the engagement sizes lean enterprise, so a merchant with a forty thousand dollar budget and a single storefront sits under the band this structure is priced around.

4. Eastside Co. A Shopify Plus agency that also builds and publishes its own Shopify apps, which gives useful platform depth. Fit note: an agency that publishes apps has a natural pull toward its own catalogue, so ask early which parts of the proposed solution are proprietary and what the ongoing subscription position looks like.

5. Barrel. A New York agency combining brand strategy and creative with Shopify commerce work for consumer brands. Fit note: the centre of gravity is brand and creative, so a merchant whose hardest requirement is a two way integration with an enterprise resource planning (ERP) system should confirm who owns that engineering.

6. Electric Eye. A United States Shopify agency serving growing consumer brands, pairing store work with retention and email programmes. Fit note: the team is built for growth stage merchants rather than enterprise governance, so procurement heavy organisations with formal security reviews will find the process lighter than they expect.

7. Fostr. A United Kingdom Shopify Plus agency with a premium brand portfolio and strong design craft. Fit note: the price band sits at the upper end and the work is brand led, which is right for a repositioning and expensive if your actual problem is operational complexity behind the storefront.

8. Blend Commerce. A Shopify agency oriented toward ongoing growth work, conversion improvement and retention rather than one off builds. Fit note: the model is retainer first, so a merchant wanting a defined build with a clear finish line is buying into a relationship shape designed for continuous iteration.

9. Zehner. A United States agency working with established consumer brands on Shopify Plus, with strong creative and technical range. Fit note: the fit is established brands with real revenue, which means a first time Plus merchant may be paying for a level of process the current stage does not require.

10. Charle Agency. A United Kingdom Shopify Plus partner working with mid market merchants, accessible relative to the premium end of the market. Fit note: a smaller team means finite concurrent capacity, and multi region rollouts with several storefronts and languages sit outside the shape of work this model is built around.

Budget bands for a Plus build

Quotes fall into three shapes. A Plus migration or rebuild on a well structured theme, with your brand, content migrated and a handful of apps configured properly, runs roughly twenty five thousand to sixty thousand dollars over eight to fourteen weeks. A custom Plus build with a bespoke design system, three or four live integrations, business to business pricing and genuine custom logic runs roughly eighty thousand to two hundred thousand dollars over four to eight months. A multi storefront estate with several markets, currencies, languages and an enterprise resource planning sync starts above two hundred and fifty thousand dollars and phases across a year. The Plus platform fee sits on top of all of these as a separate commitment.

Integrations move the number more than design does. Each genuine two way connection carries discovery, authentication, field mapping and failure handling, and a legacy system reachable only through a nightly file drop can cost more than the storefront itself. Checkout customisation is the second driver, and the third is catalogue complexity, since option combinations beyond the platform's variant handling force a data modelling exercise before any theme work begins.

The app stack decision that sets your running cost

Plus merchants routinely spend more per year on apps than on the agency that built the store, and almost nobody budgets for it. Before signing, ask for the proposed app list with monthly cost, what each one replaces, and what happens to your data if it is removed. Then ask which of them the agency would build instead and what that would cost once. Some subscriptions are excellent value. Others are a recurring fee for a feature that would have been three days of work. Also confirm which apps write to order metafields, because two apps writing to the same field is the most common cause of orders that look correct in the admin and wrong in the warehouse.

Contract points and getting from ten to one

Keep the repository in your own account from day one with the agency added as a collaborator, and take intellectual property assignment invoice by invoice rather than at final payment. Register every app subscription, the Plus contract and the payment gateway to your company. Ask for a written record of every checkout rule implemented and where it lives, because that document is what the next agency needs on day one. Name the engineers with a notice period for substitutions. Then brief all finalists identically and ask three questions: what will you refuse to put in checkout, which apps would you remove, and who is actually writing the code. To see how a team reasons about commerce decisions before you commit budget, the Digital Marketing Heroes YouTube channel is public. Finish with two reference calls and ask what went wrong on each build.
