Shopify Stores & Apps
A slow, generic theme is losing you sales you'll never see in the analytics. We build custom Shopify themes, private apps, and full store builds tuned to a 95+ Lighthouse score — so the store converts the traffic you're already paying for.

Who is a Shopify developer in Miami for custom themes and apps?
Cuanto Labs is a Miami-area Shopify development team. We build custom Liquid themes, private apps with Shopify Functions and extensions, and full store builds. Projects start at $5K, fixed price, and take 3–6 weeks, with app integrations such as Klaviyo and reviews included in the scope.
How much does a custom Shopify store cost in the US?
Cuanto Labs Shopify builds start at $5K. For context, OuterBox's 2026 guide puts a small professional ecommerce site at $5,000 to $25,000 or more, and a starter hosted store at $500 to $5,000 plus monthly platform fees. Our proposal gives you one fixed number before work starts.
Can a custom Shopify theme make my store faster?
Speed is part of the build: we tune themes to a 95+ Lighthouse score so the store converts the traffic you already pay for. A slow, generic theme loses sales you never see in the analytics. For an existing store we audit first, then quote the fix.
What is the difference between a theme, a private app and a full store build?
A custom Liquid theme controls how the store looks and loads. A private app adds integrations or internal workflows, built with Shopify Functions and extensions. A full store build combines both with app integrations such as Klaviyo and reviews. All three are fixed price, and the source transfers to you.
How long does a Shopify build take?
Three to six weeks. You see a working version in week two and review progress weekly, so the theme is shaped by your feedback instead of revealed at the end. Price and timeline are fixed in a written proposal before any code exists, and code, repositories and accounts transfer to you at launch.

More questions
Can you fix a slow store without rebuilding it?
Often, yes. Most slow stores carry app scripts they no longer use, oversized images, and a theme doing work in the wrong place. We audit first and quote the fix.
Do you build custom Shopify apps?
Yes — private apps for integrations and internal workflows, built with Shopify Functions and extensions, delivered with the source code.
Can you migrate us from another platform?
Yes, including the URL redirect map, which is the step most migrations skip and then regret when their rankings disappear.
What does it cost?
From $5K, fixed price, agreed in writing before work starts.
