Shopify vs Custom: Which Is Right for Your Business?
Every business owner launching an online store faces the same question: Shopify or custom? The answer depends on where you are today and where you're headed.
Here's the real comparison — not the one Shopify's marketing team wants you to see, and not the one custom dev shops use to upsell you.
The Case for Shopify
Shopify dominates e-commerce for good reason. For many businesses, it's the right call.
What Shopify Does Well
Speed to market. You can have a functioning store live in a weekend. Pick a theme, add products, connect Stripe, and you're selling. No developer needed.
App ecosystem. Need email marketing? There's an app. Subscription boxes? App. Loyalty programs, reviews, upsells — Shopify's app store covers nearly everything.
Managed infrastructure. Hosting, SSL, PCI compliance, CDN — Shopify handles it. You never think about server maintenance or security patches.
Proven checkout. Shop Pay converts. Shopify's checkout has been optimized across millions of stores and billions of transactions.
Where Shopify Costs You
Transaction fees. Shopify takes 0.5–2% of every sale on top of payment processing fees (unless you use Shopify Payments exclusively). On $500K/year in revenue, that's $2,500–$10,000 in platform fees alone.
Monthly costs compound. Basic Shopify is $39/month, but most real stores need Advanced ($399/month) plus apps. The average Shopify store spends $200–$500/month on apps. Over two years, that's $5,000–$12,000 in recurring costs — before transaction fees.
Template limitations. Shopify themes are rigid. Want a custom product configurator? A unique checkout flow? A non-standard content layout? You're fighting the platform, not building with it.
Platform lock-in. Your store lives on Shopify's infrastructure. Your data, your templates, your customer relationships — all tied to their ecosystem. Migration is painful and expensive.
Performance ceiling. Liquid (Shopify's templating language) is slow. Heavy apps inject JavaScript that tanks page speed. Your Google PageSpeed score drops, and so do your rankings.
The Case for Custom
Custom e-commerce means building your store on open-source infrastructure you own. Modern headless platforms like Medusa.js give you Shopify-level features without the platform tax.
What Custom Does Well
Zero transaction fees. You pay Stripe's processing fee (2.9% + $0.30) and nothing else. No platform cut. On $500K revenue, that saves $2,500–$10,000/year vs. Shopify.
Total design control. Your store looks exactly how you want it. Custom product pages, unique shopping experiences, brand-specific flows — no template constraints.
Performance. A custom Next.js storefront on Vercel loads in under a second. No bloated apps, no Liquid rendering bottleneck. Better Core Web Vitals = better SEO = more organic traffic.
You own everything. Your code, your data, your infrastructure. No platform can change pricing, ban your product category, or hold your store hostage.
Custom workflows. Unique fulfillment processes, B2B pricing tiers, multi-vendor marketplaces, complex discount rules — custom code handles what apps can't.
The Real Cost of Custom
Higher upfront investment. A custom Medusa + Next.js store runs $8,000–$25,000 to build. That's 2–5x what a Shopify setup costs initially.
You need a developer. Bug fixes, feature additions, and platform updates require a developer (or agency) relationship. You can't DIY it the way you can with Shopify's admin.
Longer launch timeline. 4–8 weeks for a custom build vs. a weekend for Shopify. If time-to-market is critical, that gap matters.
The Two-Year Cost Comparison
Let's run real numbers for a store doing $300K/year in revenue:
| Cost | Shopify | Custom (Medusa) |
|---|---|---|
| Platform / Hosting | $4,800/yr ($399/mo) | $240/yr (Vercel + Neon) |
| Apps / Plugins | $3,600/yr (~$300/mo) | $0 (built in) |
| Transaction Fees | $3,000/yr (1% on $300K) | $0 |
| Upfront Build | $2,000–$5,000 | $8,000–$25,000 |
| Year 1 Total | $13,400–$16,400 | $8,240–$25,240 |
| Year 2 Total | $24,800–$27,800 | $8,480–$25,480 |
By year two, the custom build is cheaper in almost every scenario — and you own the asset.
When Shopify Wins
Choose Shopify when:
- You need to sell this week — speed to market is everything
- Your product catalog is simple — standard products, standard checkout
- You're testing the market — validate before you invest
- You don't have a developer — and don't want to hire one
- Revenue is under $100K/year — the transaction fees don't hurt yet
When Custom Wins
Choose custom when:
- You're scaling past $200K/year — transaction fees and app costs compound
- Your brand needs to stand out — templates won't cut it
- You have unique workflows — fulfillment, pricing, or product configuration that apps can't handle
- Performance is a competitive advantage — SEO and conversion rates matter
- You're building a DTC brand — and want to own the customer relationship end-to-end
The Middle Path
You don't have to choose forever. Many of our clients start on Shopify to validate their business, then migrate to custom once revenue justifies the investment. That's not failure — that's smart staging.
The mistake is staying on Shopify after you've outgrown it because migration feels scary. The longer you wait, the more it costs.
