Core Web Vitals

Shopify headless / Hydrogen

FAQ

Frequently asked questions.

  • How long does it take for a Shopify store to be ready for sales?

    It depends on the project — we don't give generic deadlines. After reviewing your case, we will provide a clear calendar with delivery dates. Standard stores: weeks, not months. Large projects with data history: we'll give you the complete plan before starting. We prefer to deliver well over delivering quickly.

  • Do you only work with Shopify?

    Exclusively. We program in Liquid (Shopify's proprietary language) and also work with Hydrogen (Shopify's advanced technology for ultra-fast stores). This specialization allows us to solve things that agencies working with many platforms cannot.

  • Do you do marketing, ads, or social media management?

    No. We build and optimize the store: design, speed, Google positioning, and complete setup. If you need marketing or or advertising, we can recommend partner agencies.

  • What support is there post-launch?

    Monthly maintenance plans with guaranteed response times: we fix problems, add new features, and make sure your store stays fast and runs smoothly.

  • What is the migration process like from WooCommerce or Magento?

    We review your current store, export all your products, customers, and orders, replicate the design with speed improvements, and ensure that Google doesn't lose your ranked pages. We conduct comprehensive tests and migrate when your store has less traffic to avoid affecting sales.

  • Where are your clients located? Do you work with brands in the US?

    Yes. Our main focus is on stores in the U.S. — brands that sell directly to consumers in the American market. We also work with Shopify brands from Mexico, Colombia, Chile, Peru, and Ecuador. We operate 100% remotely in Spanish, during American business hours.

  • How much does a Shopify store built by Cartia cost?

    It depends on the scope. A store with a custom template starts at USD 800. A template designed and developed from scratch for your business starts at USD 2,500. Shopify Plus with full migration starts at USD 8,000. We quote each project without obligation in less than 48 hours. No intermediate steps.
