Who builds online stores on Long Island? Designs By Dave O. We have engineered Shopify and WooCommerce stores from Roslyn Heights since 2007: new builds, replatform migrations that keep your rankings, and B2B wholesale systems. One local team handles the store, the product feeds, and the marketing behind them.
E-Commerce Solutions, done right.
Custom Shopify Builds
Theme design and development built around your catalog and your customers.
Replatform Migrations
Move from any platform without losing products, customers, or rankings.

Dual pricing, customer groups, and quote workflows alongside retail.

AI-Powered Merchandising
Smart recommendations and automation that lift average order value.
Product Feed Optimization
Clean feeds for Google Shopping and Meta catalog ads.
A store built to sell, not just to exist.
Anyone can put products online. Getting strangers to trust you, add to cart, and come back a second time is a different discipline. We build stores around the buying experience: fast pages, frictionless checkout, honest product presentation, and the post purchase automation that turns one time buyers into repeat customers.
We work across Shopify, Shopify Plus, and WooCommerce, and we handle the unglamorous work that makes stores actually run: catalog migrations without losing rankings, B2B wholesale pricing alongside retail, payment and shipping configuration, product feeds for Google Shopping and Meta, and AI powered recommendations that lift average order value. Whether you have 12 products or 12,000, the store gets built right.
Retailers moving online or replatforming from a legacy cart
Wholesale businesses that want customers ordering self serve
Brands whose store traffic is fine but conversion is not

What businesses ask about e-commerce solutions.
Shopify or WooCommerce. Which is right for us?
Shopify for most retail businesses. Reliability and ecosystem. WooCommerce when you need deep WordPress integration or unusual customization. We’ll recommend based on your catalog and operations.
Can you migrate our store without losing SEO?
Yes. Full URL mapping, 301 redirects, and product data migration are standard in every replatform we do.
Do you handle B2B and wholesale pricing?
Yes. We build dual B2B/B2C stores with customer-specific pricing, minimums, and account workflows.
Can you improve our existing store instead of rebuilding?
Often, yes. We audit first. Sometimes conversion fixes and speed work beat a rebuild.
