New York Metro • Shopify Plus & Custom Liquid Engineering

Custom Shopify & Plus Development in New York City

Q: Why invest in custom Liquid development instead of an app-heavy Shopify store?

Every third-party Shopify app installed injects external JavaScript trackers, render-blocking stylesheets, and slow API calls into your checkout funnel, often dropping mobile conversion rates by 20-35%. ONS Tech builds features—such as bundle builders, custom sticky carts, countdown timers, and product swatches—natively in lightweight Liquid and vanilla JavaScript, eliminating recurring monthly app fees and boosting Core Web Vitals to 90+ on mobile.

Q: Do you support Shopify Plus enterprise migrations from Magento, WooCommerce, or BigCommerce?

Yes. We have executed multi-million dollar catalog migrations with zero downtime. We handle customer password hashing, full historical order data transfers, 301 SEO redirects mapping, multi-currency price lists, and custom ERP/NetSuite synchronization for NYC and Tri-State enterprises.

Q: How do you optimize Shopify store speed for mobile shoppers in New York?

We optimize critical rendering paths by deferring non-essential analytics pixels, pre-loading hero product photography, purging dead app code snippets leftover in your theme, and restructuring collection filtering with instant client-side facets.

Q: Can you integrate our Tri-State warehouse ERP and 3PL fulfillment software with Shopify?

Yes. We engineer secure private Shopify apps hosted on AWS or Cloudflare Workers that listen to Shopify webhooks and synchronize bi-directional inventory, orders, tracking numbers, and returns with NetSuite, SAP, Brightpearl, ShipBob, or proprietary warehouse systems.

Q: Do you build Headless Shopify storefronts using Shopify Hydrogen in New York?

Yes. For high-growth DTC fashion, cosmetics, and luxury brands in Manhattan requiring sub-500ms page transitions and bespoke dynamic shopping experiences, we build headless architectures using Shopify Hydrogen and Oxygen backed by Shopify Storefront GraphQL API.

Q: What is your collaboration model during Eastern Time (ET) hours?

We provide guaranteed synchronous overlap from 10:00 AM – 3:00 PM Eastern Time. You work directly with senior Shopify engineers via Slack and weekly video sprint reviews, ensuring fast feedback loops and rapid feature turnaround.
