Avelize - Shopify Expert Agency

The premier Shopify Plus agency for New York’s top brands.

Avelize is a premier Shopify Plus development and web design agency serving enterprise ecommerce brands in New York and globally.

What does a Shopify Plus agency do?

A Shopify Plus agency builds and maintains stores on Shopify's enterprise tier, where the work extends past theme customisation into checkout extensibility, Shopify Functions, B2B configuration, multi-store setups, and API integrations with ERP and OMS systems. Plus unlocks capabilities the standard plan does not — scripted checkout logic, higher API limits, and expansion stores — and those capabilities are what agency engagements are typically built around. The practical difference from a standard Shopify build is that Plus work is usually integration-led: the storefront is one part of a system that includes inventory, fulfilment, and finance.

How we work with New York brands

  1. Diagnose before proposing: We start with a crawl, Search Console and analytics review to establish which pages earn impressions, which earn links, and where the funnel actually loses people. Proposals that skip this stage are selling a service rather than solving a problem.
  2. Rank the work by revenue impact: Fixes are ordered by expected impact, crawlability risk, conversion risk and implementation effort. It is common for the highest-return item to be unglamorous — delivered cost shown earlier, a broken mobile variant selector, a template that renders its main content only after a client-side fetch.
  3. Ship in controlled releases: Changes go out in increments that can be attributed and reversed, not as a single relaunch. Content rewrites ship separately from design changes so the effect of each is measurable.
  4. Measure in Search Console and analytics: Every change has a defined before-and-after measure agreed in advance. We report what did not work alongside what did — a programme that only reports wins is selecting, not measuring.

New York Shopify Experts FAQs

Do you offer Shopify SEO as well as development?

Yes, and for most New York brands that reach us the SEO work is the reason. Technical SEO on Shopify is a development discipline: crawl and indexation behaviour, rendered HTML, collection and tag URL architecture, canonical handling, structured data, internal linking, and the performance cost of the app stack. Separating it from engineering is why it usually stalls.

Do we need to be in New York to work with you?

No. The work is remote by default and we work with brands across the United States and internationally. What matters more than geography is whether your team can make decisions on scope and sign off on changes without a long internal chain.

How do you price engagements?

Scoped projects for defined deliverables such as a build, a migration or an audit, and retained monthly capacity for ongoing optimisation. We prefer scoping a diagnostic first, because a proposal written before anyone has looked at the store is a guess with a number attached.

What if our problem is paid acquisition cost, not the store?

Then the store is usually still where the leverage is. Rising acquisition cost is felt as a media problem and solved as a conversion and retention problem — the same traffic converting at a higher rate, or customers returning without being reacquired. We look at the funnel and the repeat purchase data before agreeing that the answer lies in the ad account.

Can you work with our existing team or agency?

Yes. We frequently work alongside an in-house team or a creative agency, taking the engineering and technical SEO side while they keep brand and campaign work. Clear ownership boundaries matter more than who does what — most friction in that arrangement comes from two parties editing the same templates without a process.
