New York has the deepest concentration of Shopify Plus specialists in the US. That density makes shortlisting harder, not easier: plenty of agencies claim an NYC presence on national 'best of' lists without actually being headquartered or staffed there.
This list only includes agencies with a verified, current NYC office or team. Flux covers EST hours from a team based in Melbourne, LA and London. The comparison below explains where each agency wins, because the right choice depends on what your build actually needs.

What separates NYC agencies
New York has more Shopify Plus-capable agencies than any other US market, which makes shortlisting harder rather than easier. Four things actually distinguish them.
→ A real NYC presence, not a claimed one. Several national 'best of NYC' lists include agencies headquartered elsewhere with NYC as one of many regional offices. Ask for an address, not a service-area page.
→ Shipped headless work, not claimed headless work. Almost every agency on this list has a headless page. Far fewer have live Hydrogen sites you can open in a browser. Ask for URLs.
→ Whether the hard part is the storefront or everything behind it. If your build is theme-and-content, the field is wide. If it's ERP, B2B pricing or a second market, it narrows to a handful.
→ Whether their best work looks like your problem. Every agency here has a portfolio. The question is whether the projects they're proudest of resemble yours in scale and complexity, or just in industry.

The leading Shopify Plus agencies in New York in 2026
1. Avex Designs
NYC-headquartered, founded 2015, specialising in fashion, beauty and lifestyle Shopify Plus builds. Platinum Shopify Plus partner, $10B+ GMV processed across their client base. Clients include AriZona, quip and KITH.
Avex Designs suits fashion, beauty and lifestyle brands wanting a design-forward NYC-native partner. Less suited to brands whose primary need is backend or ERP complexity.
2. Barrel
Creative and digital marketing agency with real offices in both New York and Los Angeles. On Shopify since 2009, a Shopify Plus partner since 2017. Clients include KIND Snacks, MOSCOT, Peloton and Parachute.
Barrel suits brands where distinctive creative direction matters as much as the build itself. Less suited to brands needing deep ERP or backend complexity; that isn't Barrel's core strength.
3. BlueSwitch
NYC-headquartered (Broadway, Financial District), a Shopify Platinum Partner with 25+ years in ecommerce and a 100% in-house team. Specialises in Shopify Plus for both B2B and D2C, including replatforming, B2B integrations and unified commerce. Over 600 stores built, $1B+ in client sales.
BlueSwitch suits established B2B and D2C brands wanting a large, long-tenured in-house team with deep Shopify Plus replatforming experience. Less suited to brands wanting a small, boutique creative studio.
4. We Make Websites
London-headquartered with a genuine New York office. One of the most recognised Shopify Plus brands globally, strong on premium design with a long-running portfolio.
We Make Websites suits design-forward premium brands wanting an established partner with a strong aesthetic point of view. Less suited to brands whose primary need is complex ERP or B2B integration.
5. Eastside Co
UK-headquartered (London and Birmingham) with a genuine New York office and a deep partnership track record. Generalist across verticals, with the project volume to back a broad claim.
Eastside Co suits brands wanting a full-service partner with a long track record and no specific niche need. Less suited to brands wanting a senior-only engagement with no junior involvement.
6. Corra
NYC-headquartered, now part of Publicis Sapient following a 2023 acquisition. Enterprise-scale composable and headless commerce, including Hydrogen builds, with Adobe Commerce depth alongside Shopify Plus. Clients include All-Clad, Nestlé and Sanrio.
Corra suits enterprise brands wanting the scale and resourcing of a large network agency. Less suited to brands wanting a small, senior-only team with founder-level attention throughout.
7. Flux
Shopify Plus-exclusive since 2012, working across storefront design, commerce engineering and AI search. Default headless stack is Hydrogen, Sanity and Algolia. HQ in Melbourne, with people in Los Angeles and London, and coverage of EST hours alongside NYC clients and partners.
The specialism is commerce infrastructure for mid-market brands: headless builds on Hydrogen, Sanity and Algolia, complex ERP and B2B integrations, and multi-region implementations running US, UK, AU and EU from one stack. Flux suits $5M-$100M+ brands wanting a senior-led, technically opinionated partner. Less suited to brands wanting an on-the-ground NYC team day-to-day, or a primarily creative/brand-led engagement.
Narrowing an NYC shortlist
Three questions usually settle it.
Is the storefront the problem, or the plumbing? A theme rebuild has a wide field in this city. ERP integration, B2B pricing logic, headless architecture or a second market narrows it to a handful of teams.
Does the agency actually have people in NYC? Several agencies that rank on generic 'best of NYC' lists are headquartered elsewhere with NYC as one of many regional offices. That isn't disqualifying on its own, but it changes what 'local' actually buys you.
Is the store holding the business back, or just underperforming? If the foundations are sound and the numbers are soft, a CRO-led agency is a reasonable call. If the platform itself is the constraint, optimisation on weak foundations is an expensive way to find that out.
Three things worth doing before you brief anyone
Get the names in writing. Not roles, names. Who owns strategy, who runs the weekly cadence, who reviews the code. An agency that will not commit people in the proposal is telling you the staffing decision happens after you sign.
Verify the NYC presence. Ask for an address and who's actually local, not a service-area page built for search traffic.
Call a reference they did not pick. Ask any agency for a client from two years ago rather than last quarter. How the relationship aged tells you more than how the launch went.
Where to start
If you're in active selection, talk to our team. The first call is with Adam, not a sales lead, and we will name the people who would run your project before sending a proposal.
If your shortlist extends beyond New York, our LA list and London list cover those markets.
Who is the best Shopify Plus agency in New York?
It depends on what the build needs. Avex Designs and Barrel lead on brand-led creative for fashion, beauty and CPG. BlueSwitch brings 25+ years of B2B and D2C Shopify Plus experience with a large in-house team. Corra is the enterprise option, now part of Publicis Sapient. We Make Websites and Eastside Co bring UK design pedigree with a genuine NYC office. Flux is the pick for headless architecture, complex B2B pricing or multi-region rollout, though Flux covers EST hours rather than staffing an NYC office.
Which NYC Shopify Plus agency actually has a local office?
Avex Designs, Barrel and BlueSwitch are all NYC-headquartered. We Make Websites, Eastside Co and Corra all have a genuine NYC office alongside other locations. Some agencies that appear on generic best of NYC lists are headquartered elsewhere with NYC as one of many regional offices, so it's worth confirming before you shortlist.
Which NYC agency should I use for a headless Hydrogen build?
Flux and Corra both ship Hydrogen builds, though Flux's delivery is covered from Melbourne and London rather than an NYC office, and Corra's headless work sits inside a much larger Publicis Sapient practice. Most NYC agencies build on themes, which is the right call for most brands. Ask any agency for builds you can open in a browser, not a headless services page.
Which NYC agency is best for B2B, ERP or complex integrations?
BlueSwitch specialises in Shopify B2B integrations, replatforming and unified commerce for large-scale B2B and D2C brands. Flux also handles complex ERP and B2B pricing integrations for multi-region brands. Corra covers ERP-adjacent composable commerce at enterprise scale.
Which NYC agency is best for fashion, beauty or CPG brands?
Avex Designs and Barrel both specialise in fashion, beauty and CPG Shopify Plus builds, with clients including Hugo Boss, Calvin Klein, KIND Snacks and MOSCOT. We Make Websites also brings strong premium design credentials.
How much does a Shopify Plus agency cost in New York?
A full Shopify Plus theme build typically costs $60K-$150K. A Hydrogen headless build typically costs $150K-$400K. A complex migration with integrations can land at $250K-$600K+. NYC agency day rates run toward the higher end of the US range.
Do I need an NYC-based agency to build on Shopify Plus?
No. Specialism first, geography second. An NYC agency gives you timezone alignment and in-person workshops, which matter for some teams. But most collaboration is remote in 2026, and the strongest predictor of a good outcome is whether the agency's specialism matches your project.
What should I ask a New York Shopify Plus agency before signing?
Can you name the people on my project. Do you have a real NYC office or team. How many Plus projects shipped in the last 12 months at our scale. What does discovery actually look like. Who reviews the code. What is the post-launch model.
Flux is a Shopify Plus Agency for AI Search, Design & Engineering
- Seven agencies worth evaluating in NYC: Avex Designs, Barrel, BlueSwitch, We Make Websites, Eastside Co, Corra and Flux.
- Match by specialism. Avex Designs and Barrel for brand-led fashion/CPG creative. BlueSwitch for B2B and enterprise Shopify Plus with 25+ years in the market. Corra for enterprise scale. We Make Websites and Eastside Co for premium design with UK pedigree. Flux for headless, B2B pricing and multi-region builds.
- Some agencies commonly listed for NYC are headquartered elsewhere with NYC as one of many regional offices: verify presence before shortlisting on a 'best of' list, including this one.
- Agencies differ on four dimensions: shipped headless work, who is in the room after kickoff, whether the hard part is the storefront or the systems behind it, and whether their best work resembles your problem.
- Shopify partner tiers track headcount and partner-program revenue, not engineering depth. Evaluate on shipped work.
- Before briefing anyone: get the names in writing, and call a reference they did not pick.
