Junior devs, cookie-cutter themes
- Build handed to a junior
- Recycled template for every client
- Looks over speed and conversion
- Slow, unclear communication
- No support after launch

FAQ
Questions Shopify founders ask us
Do you only build on Shopify?
Yes. We focus exclusively on Shopify and Shopify Plus, so our themes, apps, and integrations are built specifically for the platform.
How much does a Shopify build cost?
Most custom builds start around $5,000 and scale with complexity. Ongoing development retainers start at $3,000/month. You get a fixed quote before any work begins.
How long does a build take?
You’ll get a project plan in 48 hours. Most custom themes ship in 3 to 6 weeks; larger Shopify Plus and headless builds take longer depending on scope.
Will my store be fast and SEO-friendly?
Yes. We build for Core Web Vitals and clean, semantic markup, so your store loads fast and stays search-friendly out of the box.
Do you offer fixed-price projects?
Yes. Most builds are quoted as fixed-scope projects so you know the cost upfront. Ongoing work runs on a flexible monthly retainer.
Can you work from our designs?
Yes. We build from your Figma or design files, or our team can handle design too. Either way you get a pixel-perfect, conversion-focused build.
Can you migrate my store to Shopify?
Yes. We migrate from WooCommerce, Magento, BigCommerce, and others to Shopify or Shopify Plus, with no lost data, products, or SEO.
Do you build custom Shopify apps?
Yes. We build custom public and private Shopify apps and integrations on the latest APIs when your store needs functionality off-the-shelf apps can’t cover.
Do you work with US and UK Shopify brands?
Yes. We build for DTC Shopify and Shopify Plus brands across the US, UK, and other English-speaking markets.
What makes you different from other Shopify development agencies?
Senior developers on every build, clean and maintainable code, conversion and speed engineered in, full QA, and post-launch support, with fixed-scope quotes.
How much does it cost to hire a Shopify development agency?
It depends on scope. Custom theme builds typically start around $5,000, full builds and migrations run higher, and ongoing development retainers start at $3,000/month. You get a fixed quote before any work begins.
Should I hire an agency or a freelancer?
A freelancer suits small, well-defined tasks. For a growing store where a failed build or migration would cost real revenue, an agency gives you a senior team, dedicated QA, a clear point of contact, and post-launch support.
Is my store ADA and accessibility compliant?
We build to accessibility best practices (semantic markup, contrast, keyboard navigation) and can run an accessibility audit on your existing store to identify and fix issues.
Who is my point of contact during the project?
You work with a dedicated project lead plus the senior developer on your build, with a live staging store and clear milestones so you always know the status.
Do you work with Shopify Hydrogen?
Yes — we have experienced Shopify Hydrogen developers for headless builds where performance and custom UX matter. For most stores, a well-built Online Store 2.0 theme is faster to ship and easier to maintain, and we'll recommend whichever fits your roadmap.
What does a Shopify development agency do?
A Shopify development agency designs, builds, and maintains stores on Shopify and Shopify Plus. Where a freelancer typically handles one piece, an agency brings a full team, senior developers, designers, QA, and project management, under one roof. At Optimize Goal that means custom theme development, new store builds, replatforming and migrations, custom app and API work, headless storefronts on Hydrogen, and ongoing performance and conversion optimization.
For a small, well-defined task, a freelancer can be faster and cheaper. For a growing store where downtime or a botched migration would cost real revenue, an agency is the safer choice: you get redundancy, dedicated QA, a clear point of contact, and support after launch. If your roadmap is complex or your store is your main revenue channel, the agency model protects you.
Every build is led by a senior Shopify developer, written in clean and well-documented code your team can extend, and engineered for Core Web Vitals and conversion, not just how it looks in a demo. We work to fixed-scope quotes, build on a staging store you can review at any time, run full QA across devices and browsers, and stay on for support once you are live. Whether you need a custom theme, a Shopify Plus build, a migration from WooCommerce or Magento, a custom app, or a headless storefront, the goal is the same: a fast, reliable store that converts and is easy to grow.
