Shopify powers millions of online stores, and for good reason: it's fast to launch, reliable, and handles hosting, security, and checkout for you. But "launching on Shopify" can mean anything from a weekend theme install to a multi-month custom build.

This guide explains the real choices you'll make, what each one costs in time and money, and where most stores go wrong.

Is Shopify the right platform for you?

Shopify is the best fit for most small to mid-size brands that sell physical or digital products with fairly standard processes. It's a weaker fit if your business depends on very complex B2B pricing, unusual product configurators, or deep custom workflows — those may suit Magento or a custom build better.

If you're still comparing platforms, read our Shopify vs WooCommerce vs Magento vs custom comparison first.

The four ways to build a Shopify store

ApproachBest forTypical timeline
Free or premium theme, lightly customizedNew brands, small catalogs, tight budgets1–3 weeks
Premium theme, heavily customizedGrowing brands wanting a distinct look fast3–5 weeks
Fully custom themeBrands where design and experience drive sales6–10 weeks
Headless (Hydrogen / Next.js)High-traffic brands needing speed and full freedom3+ months

1. Theme-based store

Shopify's Online Store 2.0 themes are flexible. With the theme editor, sections, and a few custom blocks, a good developer can turn a premium theme into something that feels like your brand — without the cost of starting from scratch.

2. Custom theme

A custom Liquid theme is designed and built around your products and customers. You get exactly the layouts you need, cleaner code with no unused features, and usually a faster store.

3. Headless Shopify

In a headless build, Shopify runs products, inventory, carts, and checkout, while a custom frontend (Shopify's Hydrogen or a framework like Next.js) handles everything customers see. It's the most flexible option, but it costs more to build and maintain, so it's worth it mainly for larger brands.

Apps: useful, but they add up

Shopify's app store covers reviews, subscriptions, upsells, loyalty, search, shipping, and more. Two common problems:

  • Monthly costs creep up. Ten apps at a modest monthly fee each quickly becomes a significant bill.
  • Speed suffers. Many apps load their own scripts on every page, slowing your store and hurting conversions and SEO.

A good rule: use an app when it solves a real problem well, remove apps you don't actively use, and consider a small custom app or theme feature when you'd otherwise pay for a large app just to use one small part of it.

Migrating to Shopify

Moving from WooCommerce, Magento, or another platform is very common. A clean migration covers:

  1. Products, variants, and images, with correct options and inventory
  2. Customers and order history, so returning buyers can still see past orders
  3. 301 redirects from every old URL to the new one, to protect your search rankings
  4. SEO data — page titles, meta descriptions, and structured data
  5. Replacing plugins with apps or theme features that do the same job
  6. Testing checkout, taxes, shipping, and emails before going live

Skipping redirects is the most costly mistake we see — stores can lose a large share of their organic traffic overnight.

Shopify vs Shopify Plus

Shopify Plus is the enterprise plan. It's worth considering when you need:

  • Checkout customization beyond what standard plans allow
  • B2B features such as company accounts and customer-specific pricing
  • Automation with Shopify Flow
  • Multiple stores for different countries or brands
  • Very high order volume during sales and launches

If none of these apply, a standard plan is usually enough — and you can upgrade later without rebuilding your store.

What drives the cost of a Shopify build

The biggest factors are:

  • Design: customized theme vs fully custom design
  • Catalog size and complexity: number of products, variants, and filters
  • Integrations: ERP, CRM, inventory, accounting, marketplaces, and shipping systems
  • Custom functionality: product builders, bundles, subscriptions, wholesale portals
  • Migration: how much data you're moving and how messy it is
  • Ongoing support: updates, new features, speed tuning, and app management

Ask for a feature-by-feature estimate rather than a single number, so you can see what each part costs and decide what can wait until after launch.

Common Shopify mistakes to avoid

  • Installing too many apps and ending up with a slow store
  • Launching without redirects from an old site
  • Ignoring mobile — most Shopify traffic is on phones
  • Writing thin product pages with no real descriptions, FAQs, or reviews
  • Not setting up analytics and conversion tracking before launch
  • Over-building version one instead of launching and improving with real data

Frequently asked questions

How long does it take to build a Shopify store?

A store on a customized premium theme usually takes 2–4 weeks. A fully custom-designed theme takes 6–10 weeks, and larger builds with migrations, custom apps, or a headless storefront can take 3 months or more.

Should I use a premium theme or a custom Shopify theme?

Start with a premium theme if your products and brand fit a common layout and you want to launch quickly. Go custom when your brand experience is a key selling point, or when you need layouts and features that a theme would only manage with heavy workarounds.

Can I move my WooCommerce or Magento store to Shopify?

Yes. Products, customers, and order history can all be migrated. The important parts are keeping your URLs working with 301 redirects so you don't lose search rankings, and checking that the apps you choose cover what your old plugins did.

Do I need Shopify Plus?

Most stores don't. Plus makes sense for high-volume brands that need checkout customization, B2B features, automation with Shopify Flow, or multiple stores for different markets.

What is headless Shopify?

Headless Shopify keeps Shopify as the backend for products, carts, and orders, but replaces the storefront with a custom frontend built in Hydrogen or Next.js. It gives you full design freedom and speed, at a higher build and maintenance cost.
