In short

Shopify development covers store architecture, custom theme engineering, app development and headless commerce on Shopify and Shopify Plus. We focus on speed, conversion and merchant velocity.

The problem

Why this matters now

Off-the-shelf Shopify themes plus 25 apps is how stores end up with 4-second LCPs and broken Buy Now flows. Conversion suffers, paid media gets expensive, and the brand blames the channel — when the real problem is the stack.

Our approach

How Marketer Zilla delivers

We engineer Shopify stores as performance-first conversion machines. Custom themes with minimal apps, headless Hydrogen when speed demands it, and a checkout / PDP architecture proven to lift conversion 15–40%.

Plus makes sense above ~$1M GMV/year or when you need Checkout Extensibility, B2B, Markets or Functions. Below that, regular Shopify is fine.
Themed for 80% of brands. Headless (Hydrogen) makes sense when speed, SEO or design demands exceed what Liquid can deliver — typically $5M+ GMV.
Yes. We've migrated catalogs of 50K+ SKUs from Magento, WooCommerce and BigCommerce to Shopify Plus with zero ranking loss.
Almost always. Most Shopify stores can drop 30–60% of their apps with custom theme code, improving speed and lowering monthly app fees.
