Top Shopify Plus Agencies 2026: 10 Enterprise Partners Compared

Shopify Plus agencies all promise the same things: faster stores, better conversion, smooth launches. The differences only show up once a project hits an ERP that owns the catalog, a B2B price list with forty customer groups, or a checkout that has to work in six countries. This guide compares ten Shopify Plus agencies on exactly those points, explains what they cost, and gives you the questions that separate a real enterprise partner from a theme shop with a Plus badge.

Short answer: for mid-market B2B and DTC brands that need ERP integration and fixed-price phases, Presta is the most predictable option on this list (we publish this guide, so weigh that as you like, and note that Presta is a Shopify Partner rather than a member of the Shopify Plus Partner program). For subscription-heavy DTC operations, Codingkart and Swanky are the specialists. For revenue-focused builds with CRO built in, craftberry. For large international replatforms with a big creative budget, We Make Websites.

Disclosure: Codingkart and craftberry are sponsored placements. Their entries were agreed with the agencies. The rest of the ranking is editorial, based on public portfolios, reviews and conversations with merchants.

How we ranked these Shopify Plus agencies

Every agency below can build a good-looking Shopify Plus store. We ranked them on the five things that decide whether an enterprise project goes live on time and keeps paying back afterwards:

Integration depth. Can the team build and maintain a two-way ERP, PIM or WMS integration, or do they hand that to a third party?
B2B capability. Have they shipped Shopify Plus B2B with company accounts, catalogs, price lists and payment terms for real wholesale customers?
Checkout and Functions. Do they build checkout UI extensions and Shopify Functions in-house now that checkout.liquid is gone?
Delivery model. Fixed-price phases, time and materials, or a monthly retainer, and is the model written down before you sign?
Evidence. Named clients, public reviews and results you can check, rather than anonymous “Fortune 500 brand” case studies.

We did not rank by agency size. Several of the best Shopify Plus agencies for mid-market brands are teams of twenty to sixty people, where the developers you meet in the pitch are the ones who build the store.

The 10 top Shopify Plus agencies in 2026

1. Presta: The Shopify Plus Agency for B2B, ERP and Multi-Store Brands

Based in: Belgrade, Serbia, working with brands in the EU, the UK, the US and Australia since 2014.
Focus: Shopify Plus builds and upgrades where the hard part is behind the storefront: ERP integration, native B2B, multi-store groups and migrations from WooCommerce, Magento and custom platforms.
Why they lead: Presta builds the integration layer itself. For Ardon, a workwear and safety brand in Croatia, the team built a fully automated store with the catalog and stock coming from the ERP and orders flowing back, launched after six weeks of development, and saw cart abandonment fall 32%. For EP Flies, Presta merged WooCommerce products and Ecwid orders into one Shopify store with 80 to 90 colour variants per product and three price tiers for retail, wholesale and guides. The integration is built as one Shopify app that can serve every store in a group, so a second or third store is configuration rather than a new project.
Pricing: Fixed-price phases agreed after a Discovery Workshop. Shopify Plus builds and upgrades from 15,000 EUR; ERP, B2B and multi-market builds typically 20,000 to 45,000 EUR. Retainers from 50 EUR per hour in the region and 70 EUR per hour internationally.
Worth knowing: Presta is a Shopify Partner, not a member of the Shopify Plus Partner program. If a listed Plus Partner badge is a procurement requirement for you, that matters.
Signature service: Shopify Plus build with ERP integration and native B2B, delivered in fixed-price phases.

2. Codingkart: Shopify Plus Development for Complex DTC Operations (sponsored)

Focus: End-to-end Shopify Plus development for high-growth DTC brands across coffee, meal kits, wellness, pet and digital membership, with a deep specialization in checkout and subscription operations.
Why they lead: Codingkart brings 15 years of experience and 500+ projects to brands that need Shopify Plus built for real operational complexity, not just storefront aesthetics. Trusted by brands like Driftaway Coffee, one of the most recognized names in DTC coffee subscriptions. As a Shopify Plus agency, it handles everything from custom checkout flows and subscriber pricing to API integrations with Recharge, Klaviyo and ShipBob, and internal admin tools that bring fulfillment, orders and subscriber data into one place. The right partner for brands that have scaled past what generalist agencies and off-the-shelf apps can support.
Signature service: Shopify Plus build and subscription operations engineering.

3. craftberry: Shopify Plus, CRO and UX for Scaling Brands (sponsored)

Focus: Shopify Plus builds, CRO and UX for scaling ecommerce brands.
Why they lead: craftberry is a certified Shopify Plus agency that ties every technical decision to revenue impact. Conversion rate, AOV and scalability drive the work, from architecture to UX. Their client roster includes Vivo, On Running, Shelly and Pepper.
Signature service: Revenue-focused Shopify Plus builds with an integrated CRO and UX strategy.

4. Opklopper: The Design-Led Shopify Plus Partner for European Growth Brands

Focus: Custom Shopify Plus builds, brand-led UX and UI, replatforming, and scalable DTC, B2B and hybrid commerce for growth-stage European brands.
Why they lead: Opklopper is a design-led Shopify Plus Partner from Amsterdam that combines distinctive UX and UI design with senior Shopify development, CRO, technical SEO and complex integrations. With 250+ Shopify builds, redesigns and migrations, the boutique agency is an experienced partner for brands launching a new custom storefront, redesigning an existing store, or migrating from platforms such as Magento, WooCommerce and Lightspeed. Its senior team works directly with clients on Shopify Plus, international Shopify Markets, B2B functionality, ERP and fulfilment integrations, tracking and ongoing optimization. Opklopper has earned an average rating of 4.7 out of 5 across nearly 100 client reviews.
Signature service: Design-led Shopify Plus build and replatforming.

5. We Make Websites: The International Replatforming Studio

Focus: Large-scale international builds and creative luxury and fashion stores.
Why they lead: We Make Websites is one of the best-known Shopify Plus agencies in the UK, working with global consumer brands on multi-currency, multi-language and multi-market setups. The creative standard is high, which makes them a natural shortlist for fashion and luxury houses that want the storefront to carry the brand.
Watch out for: Budgets and timelines sized for large brands. Mid-market stores may find the process heavier than they need.
Signature service: International replatforming with creative direction.

6. Swanky: The Conversion and Subscription Specialists

Focus: DTC subscription brands and data-driven CRO.
Why they lead: Swanky is a UK Shopify Plus agency known for conversion rate optimization and retention. For brands that rely on recurring revenue through apps like Recharge or Bold, their lifecycle and retention-focused UX work is a strong fit.
Signature service: Lifecycle growth sprints.

7. Enavi: The Research-Led CRO Partner

Focus: Conversion rate optimization and revenue per visitor growth for large Shopify Plus stores.
Why they lead: Enavi puts qualitative customer research ahead of testing, identifies the funnel stage causing the most friction, and builds test programs around it for 8 and 9 figure Shopify Plus stores such as Baltic Born and Kitsch. Not a build agency first, but one of the stronger Shopify Plus agencies once the store is live and the question becomes growth.
Signature service: Conversion audit and 90-day growth plan.

8. Netalico: The Fractional Development Team

Focus: Fractional senior Shopify Plus developers on a month-to-month basis.
Why they lead: Netalico popularised the fractional ecommerce team model: a dedicated pod of senior developers without the cost of a full-time hire. A good fit for brands with a steady stream of technical work and no in-house team.
Signature service: Fractional Shopify Plus engineering.

9. eHouse Studio: The UX and Retention Designers

Focus: Experience design and customer loyalty.
Why they lead: eHouse Studio treats the store as a brand space and designs for retention and lifetime value rather than only for the first purchase. Strong for brands where storytelling and repeat purchase drive the business.
Signature service: Retention-first UX design.

10. Elsner Technologies: Broad Shopify Development at Scale

Focus: Shopify and Shopify Plus development for startups, SMBs and larger brands, including custom development, migrations, integrations and performance work, through its Shopify development services.
Why they lead: Over 20 years in digital commerce and a large delivery team make Elsner a practical option for brands that want one vendor for store development, apps, ERP and CRM integrations and ongoing maintenance at a competitive rate.
Signature service: Shopify Plus development, custom apps, migrations and maintenance.

How to choose between Shopify Plus agencies

Most brands shortlist three Shopify Plus agencies and then pick on chemistry. Pick on these instead.

Start with the hardest part of your project

Write down the one thing that would make your project fail. For most Plus projects it is not the theme. It is one of these:

An ERP that owns products, stock and prices. Ask each agency to describe an ERP integration they built and still maintain, and what happens when the ERP is down.
B2B. Ask to see a live Shopify Plus B2B storefront with company accounts and price lists, not slides about it.
Several markets or brands. Ask whether they use Shopify Markets, expansion stores or both, and why for a store like yours.
A migration. Ask how they validate orders and customers record by record, and how they handle URL redirects and structured data.

Then weight the shortlist by that one capability, not by the portfolio.

Check partner status, but know what it means

Shopify lists Plus Partners in its Shopify Partner Directory. Plus Partner status tells you an agency has met Shopify’s volume and quality bar and has a direct line to Shopify. It does not tell you whether they have built your kind of integration. Some of the best Shopify Plus agencies for B2B and ERP work are Shopify Partners that simply have not joined the Plus program. Ask for evidence either way.

Match the delivery model to how you buy

Fixed price per phase suits brands with a clear scope and a finance team that wants a number. Insist on a written scope and a change process.
Time and materials suits projects with real unknowns. Insist on weekly reporting and a cap.
Retainer suits ongoing development and CRO after launch. Insist on knowing who is on your account and how unused hours are handled.

Presta runs fixed-price phases for the build and an hourly retainer after launch, billed only for hours used. Several Shopify Plus agencies on this list run retainers from day one. Neither is wrong, but you should know which you are buying.

What Shopify Plus agencies cost in 2026

A Shopify Plus budget has three layers, and only one of them goes to the agency.

1. The Shopify Plus plan

Shopify publishes Shopify Plus pricing starting at about 2,300 USD per month on a three-year term or 2,500 USD per month on a one-year term. Above roughly 800,000 USD in monthly sales a variable platform fee of 0.25% of sales applies, capped at 40,000 USD per month.

2. The build or upgrade

What Shopify Plus agencies charge for the build depends far more on integrations than on design:

Project	Typical agency cost
Upgrade from standard Shopify to Plus, existing theme	10,000 to 25,000 EUR
New Plus store, custom theme, standard apps	20,000 to 60,000 EUR
Plus with ERP integration and native B2B	30,000 to 100,000 EUR
Large international replatform or headless build	100,000 EUR and up

Presta’s Shopify Plus builds and upgrades start at 15,000 EUR, and builds with ERP integration, B2B and several markets typically land between 20,000 and 45,000 EUR, fixed per phase. Agencies in London, Amsterdam and New York typically quote 1.5 to 3 times that for the same scope, mainly because of rates.

3. The retainer after launch

Most Plus stores keep an agency on retainer for new features, CRO, app changes and integration upkeep. Typical ranges are 2,000 to 5,000 EUR per month for maintenance and small features, and 5,000 to 15,000 EUR per month for an active CRO and development program. Hourly rates across the Shopify Plus agencies on this list range from about 50 EUR in Central and Eastern Europe to 150 to 200 USD in the US and UK.

Shopify Plus or standard Shopify: do you need a Plus agency at all?

Not every brand talking to Shopify Plus agencies needs Plus. Standard Shopify with a custom theme handles most stores up to several million in annual revenue. Plus earns its fee when you need:

Checkout extensibility: checkout UI extensions and Shopify Functions for discounts, delivery and payment rules.
Native B2B: company accounts, catalogs, price lists and payment terms, documented in Shopify’s B2B help center.
Expansion stores: separate stores for markets or brands under one plan.
Higher API limits: for ERP, PIM and WMS integrations that sync large catalogs often.
Launchpad and automation: scheduled launches and Shopify Flow at scale.

If none of those apply yet, a standard Shopify build with a clean upgrade path is usually the better use of budget. A good Shopify Plus agency will tell you that on the first call.

12 questions to ask Shopify Plus agencies before you sign

Use these in the second meeting, after the portfolio walkthrough.

Delivery and team

Who exactly will work on our store, and how many other projects are they on?
Is the scope and price fixed per phase, and how are changes priced?
What does your staging and cutover rehearsal look like, and who signs off?

Integrations and B2B

Which ERP integrations have you built that are still running, and who maintains them?
Can we see a live Shopify Plus B2B storefront you built?
How do you sync stock and prices, how often, and what happens if a sync fails?

Checkout, performance and SEO

Which checkout UI extensions and Shopify Functions have you shipped since checkout.liquid was retired?
How many apps did your last three launches use, and which did you replace with custom code?
How do you handle redirects, metadata and structured data in a replatform, and how long do you monitor rankings?

After launch

What is included in the first 30 days after launch?
How is the retainer billed, and what happens to unused hours?
Can we speak to a client who has been with you for more than a year?

The answers matter less than how specific they are. Shopify Plus agencies that have done the work answer with store names, numbers and trade-offs.

Frequently asked questions about Shopify Plus agencies

What do Shopify Plus agencies do?

Shopify Plus agencies design, build, migrate and run stores on Shopify Plus. The work covers the theme, checkout extensibility and Shopify Functions, native B2B, ERP and PIM integration, expansion stores, and development and CRO after launch.

How much do Shopify Plus agencies charge?

Builds and upgrades typically range from 10,000 to 100,000 EUR depending on integrations, with large international replatforms above that. Presta’s Shopify Plus builds start at 15,000 EUR in fixed-price phases. Retainers typically run 2,000 to 15,000 EUR per month.

How long does a Shopify Plus build take?

An upgrade from standard Shopify usually takes around four weeks. New Plus builds and migrations take four to twelve weeks for most mid-market brands, and longer when an ERP integration has to be built on both sides.

Do I need a certified Shopify Plus Partner?

Not necessarily. Plus Partner status shows an agency meets Shopify’s program requirements, but it does not prove experience with your ERP, B2B model or markets. Ask every agency for live examples of the capability your project depends on.

Which Shopify Plus agencies are best for B2B?

Look for agencies that can show a live Shopify Plus B2B storefront with company accounts, price lists and payment terms, and an ERP integration behind it. On this list, Presta, Opklopper and Codingkart have the most relevant B2B and integration work.

Can Shopify Plus agencies work with brands in other countries?

Yes. Most Shopify Plus agencies work remotely across time zones. Presta works from Belgrade with brands in the EU, the UK, the US and Australia, in English and Serbian, in Central European Time.
