Choosing a Shopify Plus agency for a New York brand starts with the work you need: a new store, a rebuild, migration or ongoing improvements. Compare relevant projects, the delivery team and the support after launch.
This guide includes agencies with a New York presence, plus Flux as a remote option. Flux covers EST hours from Melbourne, Los Angeles and London; we do not present that as an NYC office.
Shortlisting now? Talk to our team and we will name the people who would run your project before sending a proposal.
Editorial disclosure: Flux publishes this guide and is included in it. This is our shortlist, not an independent ranking or an audited comparison. Confirm current services, offices, partner status and delivery evidence directly with each agency.
What separates NYC agencies
Partner status can help you check an agency, but it does not replace project evidence. Shopify has announced new tier requirements from 1 January 2027. Confirm the current listing when you shortlist.
Use these four questions to compare a Shopify Plus agency for a New York project.
Who is local, and who covers your working hours? Ask where your delivery team works, whether workshops are available and what coverage is included. An office address alone does not tell you who will do the work.
What have they shipped that matches the brief? Ask for live stores and an explanation of the agency’s role. If headless is a requirement, ask about that architecture specifically; it is not a prerequisite for every new store or rebuild.
What systems and workflows must work at launch? Include ERP, fulfilment, B2B pricing and market requirements in the brief. Ask each agency for relevant integration examples.
→ 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 is worth evaluating for fashion, beauty and lifestyle work. It also publishes ERP, CRM, WMS and 3PL integration services. Ask for a comparable project and the team that would deliver yours; a design-led portfolio does not establish a limit on its engineering capability.
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 is worth evaluating where creative direction and the storefront experience matter. For ERP or backend requirements, ask for relevant delivery evidence and a clear integration scope rather than assuming capability from the agency’s positioning.
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 is worth evaluating for premium storefront work. If the brief includes ERP or B2B requirements, ask about comparable builds, ownership of the integrations and ongoing support.
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 is worth evaluating for a broad Shopify engagement. Ask who would lead strategy, design and engineering, how senior review works and which people are included in the proposal.
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.
What needs improving? Separate customer experience changes from platform, data and integration problems. Give each agency the same requirements so its proposed scope can be compared.
What does local delivery mean for your team? Confirm workshop arrangements, working hours and escalation coverage. A remote team may fit the brief, but it should be described accurately.
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?
There is no single best fit for every brief. Compare the agencies below against your category, required integrations, budget and delivery model. Flux publishes this shortlist and is included as a remote option, with EST coverage rather than an NYC office. Ask every agency for relevant work and the proposed team.
Which NYC Shopify Plus agency actually has a local office?
The profiles distinguish NYC-headquartered agencies, agencies with a New York office and Flux’s remote coverage. Confirm the current address and where your proposed delivery team works before relying on location. An office is not proof that every project role is based there.
Which NYC agency should I use for a headless Hydrogen build?
Ask for live Hydrogen stores, the agency’s role in each build and how it supports them after launch. Flux and Corra are included for headless work in this shortlist; assess the specific brief rather than treating architecture as a ranking. A theme may be the right choice when it meets the requirements.
Which NYC agency is best for B2B, ERP or complex integrations?
Compare relevant B2B and integration work from BlueSwitch, Avex, Corra, Flux and any other agency you shortlist. Ask which systems were connected, who owned the work and how failures are monitored. A broad services page is a starting point, not evidence that a particular team matches your brief.
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 Advanced Engineering & AEO
- Seven agencies worth evaluating in NYC: Avex Designs, Barrel, BlueSwitch, We Make Websites, Eastside Co, Corra and Flux.
- Match the shortlist to your category, storefront requirements, systems and markets. BlueSwitch reports 25+ years in ecommerce; that is not 25+ years of Shopify Plus experience.
- 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.
- Partner status is one check, not a substitute for delivery evidence. Shopify has announced new tier requirements from 1 January 2027.
- Before briefing anyone: get the names in writing, and call a reference they did not pick.
