Best Shopify Plus Development & Design Agencies

A Shopify Plus development and design agency is a technical partner that builds, customizes, and designs enterprise Shopify Plus stores, handling custom themes, checkout extensibility, Shopify Functions, headless builds, and API integrations. Unlike a full-service marketing agency, it focuses on building and designing the store itself rather than running ads, SEO, or email campaigns.

This guide compares 15 Shopify Plus development and design agencies and adds a vetting checklist, a Plus-versus-standard feature table, the 2026 Scripts deadlines, and cost and timeline benchmarks. It is written for merchants who need a technical build or design partner, not a marketing retainer.

How to Choose a Shopify Plus Development Partner

Choosing a Shopify Plus development agency comes down to proven builds, technical depth, design skill, transparent pricing, and a plan to protect revenue after launch. Work through this checklist before you request a single quote. Each item removes agencies that are not the right fit for an enterprise build.

• Plus-Specific Portfolio: Ask for live enterprise Plus builds, not standard Shopify stores. Migrations and Shopify Plus B2B builds are strong signals.
• Technical Depth: Confirm hands-on skill with Liquid, Shopify Functions, checkout extensibility, headless builds, and API integrations.
• Design Capability: Check whether the team handles UX and UI, or only front-end code from your designs.
• Post-Launch Support: Ask how bugs, updates, and new features are handled after go-live, and at what cost.
• Pricing Transparency: Get a written scope with a clear engagement model, whether project-based or retainer.
• Partner Status: Verify Shopify Plus Partner or Premier Partner status directly on the agency's profile.
• Revenue Protection: Confirm the build plans for fraud screening and chargeback and fraud protection with dispute-ready order data.

Treat the portfolio and technical items as pass-or-fail. An agency without live Plus builds is learning on your budget, and that risk grows with your order volume. Weigh the support model as heavily as the build itself: a store is never truly finished, so get in writing who fixes issues and ships new features after launch, along with response times and hourly rates for out-of-scope work.

Six Technical Questions to Ask Before You Sign

Ask these questions on the first call and get the answers in writing.

Which Work Truly Requires Shopify Plus?

Shopify's Functions documentation says stores on any plan can use public apps that contain Shopify Functions, but "Only stores on a Shopify Plus plan can use custom apps that contain Shopify Function APIs." The checkout UI extensions documentation adds that extensions for the information, shipping, and payment steps are "available only to stores on a Shopify Plus plan." Use the table to check whether an agency's quote is for work that needs Plus.

Ask each shortlisted agency to describe a Shopify Functions project it has shipped and which of these rows it relied on.

Shopify Scripts Deadlines Every 2026 Agency Should Know

Shopify Scripts, the older Plus-only way to customize discounts, shipping, and payment logic, were replaced by Shopify Functions. Stores that still carry Script logic need a migration plan. The dates below come from Shopify's Scripts deprecation notice and its order status script tag documentation.

Comparison Table: Shopify Plus Development & Design Agencies at a Glance

Use this table to compare each Shopify Plus development agency by specialization and engagement model. Exact pricing is quoted per project, so the model column shows how each agency tends to engage rather than a fixed rate. General market ranges appear in the FAQ below.

The 15 Best Shopify Plus Development & Design Agencies in 2026

We built this list from live Google search results for Shopify Plus agency queries. We then checked each agency against its own website and Shopify Partner status.

Every description below uses only publicly stated positioning, so no specialization or client claim is invented. Chargeflow does not build stores, which keeps this roundup independent. The agencies appear in no ranked order, since the best fit depends on your scope and budget.

Each entry summarizes what the agency says about itself, not a review of a project we ran. Treat every Shopify Plus development company below as a starting point, then confirm current work, references, and pricing directly with each team.

Netalico Commerce

Netalico Commerce is a Shopify Premier Partner with a fully in-house Americas team working US hours, according to its site. Its public positioning centers on enterprise-grade custom builds, platform migrations from Magento, BigCommerce, and WooCommerce, and conversion work for growing brands.

An in-house team on US hours tends to suit merchants who want fewer layers between brief and build. Premier Partner status is worth confirming on the Shopify directory before you engage.

Eastside Co

Eastside Co describes itself as one of the world's most trusted and experienced Shopify Plus Partners. Its site lists both Shopify web design and Shopify web development as services, aimed at ambitious brands.

Merchants who want build and design under one roof will find both stated clearly. Ask which senior team members stay on the account from discovery to launch, since continuity matters on a long enterprise build.

Fyresite

Fyresite is a Shopify Premier Partner based in Tempe, Arizona. Its public positioning centers on automotive fitment (year/make/model), B2B, and point-of-sale builds for industrial and high-catalog merchants.

That vertical focus is a strong signal if you sell complex or fitment-based catalogs. Merchants outside those niches can still engage the team, but should confirm relevant work first. Ask which project phases are handled in-house versus subcontracted before you sign.

Optimum7

Optimum7 describes itself as a Shopify development and design agency with over 15 years of experience. Its public focus is custom feature work and complex integrations.

The long track record makes it a candidate for merchants with heavy custom requirements. Deep integration needs, such as tying the store to back-office systems, fit that stated scope. Ask for an example integration similar to yours so you can judge the fit.

Shero Commerce

Shero Commerce markets Plus development for B2B and DTC brands. Its stated services are to build, migrate, and optimize enterprise stores.

That B2B and DTC split is useful if wholesale or multi-channel selling is part of your roadmap. Merchants planning a migration will want a partner that names it as a core service, as this one does. Ask how it handles data mapping and redirects, since those steps protect your search rankings.

Blackbelt Commerce

Blackbelt Commerce is a certified Shopify Plus agency. Its public positioning covers conversion optimization, migration, and search work, and it says every build starts with a baseline audit of your current funnel.

Merchants who want a data-first starting point will recognize that baseline-audit style on its site. The approach can suit teams that prefer to measure a problem before scoping a fix. Ask what metrics the audit reports, so you can judge the work against clear numbers.

Bigfolio

Bigfolio is a Los Angeles-based Shopify Plus design and development firm. Its public services span Plus build and redesign, CRO, and UX optimization for scaling brands.

The studio positions itself around growth-stage brands that have outgrown a template theme. If your current store is buckling under traffic or catalog size, that scaling focus is relevant. A regional team can also help if you value time-zone overlap during a build.

CartCoders

CartCoders states, "We build Shopify Plus stores that are easy to manage, scale faster, and help turn traffic into revenue." Its public focus includes custom checkout and headless work.

That manageability angle appeals to lean teams that need to run the store without a large developer bench. The custom checkout focus also lines up with the Plus-only build work most merchants come here for. Ask to see how a past checkout build performed on speed and completion.

Vsourz

Vsourz offers end-to-end Shopify development. Its stated services span store design, setup, maintenance, and ongoing support.

The full-lifecycle model suits merchants who want one partner from design through long-term upkeep. Ongoing maintenance as a named service helps if you lack in-house developers after launch. Clarify whether maintenance is a retainer or billed per request so costs stay predictable.

SetuBridge

SetuBridge is a Shopify Plus development company. Its public focus is custom store development and third-party integrations.

Integration-heavy builds, such as connecting an ERP or fulfillment system, fit its stated scope. Merchants whose project is mostly plumbing between systems will recognize that focus. Confirm which specific platforms it has connected before, so you avoid untested territory.

Folio3 eCommerce

Folio3 eCommerce is a Plus development agency with a focus on automation. Its public positioning highlights order routing, custom development, and a hire-developer engagement model.

That model works for merchants who want dedicated developers embedded in their own roadmap. The automation focus can pay off for brands with complex order flows across warehouses or regions.

Liquify

Liquify says it has been an officially recognized Shopify Partner and Expert since 2014. It lists development, design, and marketing under a small team that specializes only in Shopify.

A smaller team can be a fit when you want tight collaboration on a focused build. Small, Shopify-only studios often trade breadth for a closer working relationship, which some merchants prefer.

Magebit

Magebit is a full-service ecommerce agency whose Shopify services include Shopify Plus development, Shopify B2B development, and dedicated Shopify developers. It also publishes a "Top Shopify Agencies in 2026" ranking, written by a Magebit co-founder, that places Magebit first, so read it as vendor-authored research.

The dedicated-developer option suits teams that want added capacity inside their own roadmap. Larger agencies can bring more capacity, so ask who will actually work on your account.

Atwix

Atwix describes itself as a Shopify Plus Partner. It also builds on Adobe Commerce, Magento Open Source, Shopware, and BigCommerce, and it ranked No. 2327 on the 2025 Inc. 5000 list. Its site centers on B2B buyers who order by SKU, in bulk, and on a budget cycle.

B2B merchants with custom pricing or account logic will recognize that focus. Because Atwix is a cross-platform agency, confirm its recent Shopify Plus case studies before you engage. If your model includes wholesale portals or tiered pricing, name that in your first call.

DigitalSuits

DigitalSuits describes itself as a Shopify Plus and AI development agency. Its site lists Shopify CRM and ERP integrations alongside custom software and app work.

Custom app and software work fits merchants whose requirements do not map cleanly to an off-the-shelf theme or app. Bespoke work costs more up front, so weigh it against the value of a custom flow.

Development vs. Design: Do You Need Both?

Not every project needs a full team, so scope the work before you scope the partner. The four cases below cover most Plus projects.

• Development only: Choose it when the job is checkout logic, Shopify Functions, integrations, migration, or a headless build.
• Design only: Choose it when your store works well but needs UX, UI, or brand refinement.
• Both: Choose both when you are launching, replatforming, or running a full redesign at the same time.
• A broader partner: Choose one when you also need marketing and strategy, and see our list of top Shopify Plus agencies.

Writing this down early saves money. It stops you from paying for a full-service engagement when a focused developer would do, or the reverse.

If you are unsure, start with a small paid discovery or audit. A short engagement reveals how a team communicates and estimates before you commit to a full build.

Protecting Your Build: The Revenue Layer Most Briefs Miss

A custom checkout can lift conversion, but it also changes how fraud reaches your store, because the rules and data that decide which orders get through live in the build. Name three things in the brief: fraud screening, dispute-ready order data, and chargeback defense. Our guide to Shopify Plus chargeback and fraud protection covers the full picture, and the build brief should sit inside a wider ecommerce fraud prevention plan.

Dispute-ready order data is the part an agency controls. Under Visa's Compelling Evidence 3.0 merchant readiness guide, a merchant can answer a card-absent fraud dispute (condition 10.4) by showing two earlier undisputed transactions from the same merchant, 120 to 365 days old, where at least two of four data elements match the disputed order: user ID, IP address, shipping address, or device ID or fingerprint. One of the two matches must be the IP address or the device ID. A checkout that fails to store those elements cannot use that defense.

You do not have to build protection from scratch. Chargeflow installs on Shopify with a one-click integration and needs no development work. Its chargeback alerts connect to Visa and Mastercard alert programs and report up to 90% deflection of eligible incoming disputes, while Automation handles chargeback recovery after a dispute is filed. Reviewing the best Shopify chargeback apps during scoping keeps this on the roadmap, and it pairs a strong build with Shopify fraud prevention tools without added engineering cost.

Perguntas frequentes

What Does a Shopify Plus Development Agency Do?

A Shopify Plus development agency builds and customizes enterprise Shopify Plus stores, including custom themes, checkout extensions, Shopify Functions, headless storefronts, API integrations with ERP and other systems, and platform migrations. Design-focused agencies add UX and UI work, and neither type normally runs ads, SEO, or email campaigns.

How Much Does Shopify Plus Development Cost?

Custom Shopify Plus development typically costs about $5,000 to $25,000 for individual features and $25,000 to $100,000 for substantial projects, with hourly rates of $200 to $600, according to the 2026 Shopify Plus development cost guide from ShopExperts. Rates vary by agency tier and specialization, so compare written, fixed-scope quotes rather than hourly rates alone.

How Long Does a Shopify Plus Migration or Custom Build Take?

A Shopify Plus migration typically takes about 8 to 20 weeks or more, depending on complexity, data volume, and integrations. Ecommerce Pro's realistic Shopify Plus migration timeline states that "A Shopify Plus migration can reasonably take anywhere from 8 weeks to 20 weeks or more." Smaller custom builds, such as a single checkout extension, are scoped separately, so ask each agency for a written timeline by phase, and use our Shopify Plus migration checklist to prepare before kickoff.

Is the Shopify Plus Platform Fee Included in Development Cost?

No, the Shopify Plus platform fee is separate from your development cost. According to Shopify's Shopify Plus plan pricing, the plan costs $2,300 USD per month on a 3-year term or $2,500 USD per month on a 1-year term. The main store plus 9 expansion stores are included, additional stores cost an extra $300 USD per month each or a revenue share, and higher-volume merchants move to a variable platform fee based on revenue.

What's the Difference Between a Shopify Plus Development Agency and a Full-Service Agency?

A Shopify Plus development agency builds and designs your store, while a full-service agency also runs marketing such as ads, SEO, and email. Choose the development partner when your priority is the technical build, and the full-service partner when you need growth channels handled too.

Which Shopify Plus Agencies Are Worth Shortlisting?

This guide compares 15 Shopify Plus development and design agencies in no ranked order, including Shopify Premier Partners Netalico Commerce and Fyresite. Shortlist by live Plus builds, Shopify Functions experience, and written support terms, then confirm partner status on each agency's Shopify directory profile.

How Do I Make Sure My Build Is Protected From Chargebacks and Fraud?

Protect your build by writing fraud screening, dispute-ready order data, and chargeback defense into the brief before launch, not after. Dispute-ready data means storing IP address, device ID, user ID, and shipping address on every order, because Visa's Compelling Evidence 3.0 matches on those elements. Tools like Chargeflow install in one click, so you can add this revenue layer to a finished store without a new build cycle.
