Quick Answer
Choose Shopify if you're launching a store, selling under ~$50k/mo, and need to get to market in weeks. Choose custom development if you have a business model Shopify can't fit, need unique functionality, or your volume is big enough that platform fees and performance limits cost you more than a custom build.
Shopify will cost $100–$1,500/mo all-in (fees + apps + processing). Custom development costs $25,000–$80,000+ upfront plus $500–$2,000/mo to maintain. The decision isn't about which is "better" — it's about which one fits your business model and timeline.
The Case for Shopify
What Shopify gives you
- ▪Speed to launch: 2–8 weeks, not 6 months
- ▪Everything included: hosting, checkout, payments, shipping, security — all handled
- ▪Huge app ecosystem: 8,000+ apps for almost any feature
- ▪Predictable pricing: $29–$399/mo for the platform
- ▪Low technical risk: you don't need a developer to run it day-to-day
The real cost of Shopify
The platform fee is the cheapest part:
| Line item | Cost |
|---|---|
| Shopify plan | $29–$399/mo |
| Apps (the average store runs 6+) | $100–$400/mo |
| Payment processing | 2.4%–2.9% + $0.30/order |
| Premium theme | $150–$350 one-time |
| Total for a typical store | $300–$1,000/mo |
For a store doing $50k/mo, processing alone costs roughly $1,500/mo — that's the number to watch as you scale.
When Shopify is the right call
- ▪You want to launch fast and validate a product
- ▪Your catalog is under a few thousand SKUs
- ▪You need standard features (subscriptions, discounts, reviews) — apps cover it
- ▪You don't want to manage infrastructure
The Case for Custom Development
What custom gives you
- ▪A business model, not a template: custom checkout logic, memberships, B2B pricing, marketplaces, multi-vendor — anything your idea requires
- ▪Performance: custom code loads faster, which directly lifts conversion
- ▪Lower per-transaction costs: no platform fee, and you control the payment stack
- ▪Full ownership: no platform rules, no app dependency, no migration risk later
- ▪Unique UX: your store doesn't look and behave like every other Shopify store
The real cost of custom
| Line item | Cost |
|---|---|
| Design + development | $25,000–$80,000 |
| CMS / backend setup | $3,000–$10,000 |
| Integrations (ERP, CRM, payments) | $3,000–$15,000 |
| Ongoing engineering | $500–$2,000/mo |
| Hosting + infra | $50–$500/mo |
When custom is the right call
- ▪Your business model doesn't fit a platform (complex subscriptions, marketplaces, B2B portals)
- ▪You're processing enough volume that a 0.5–1% fee difference is real money
- ▪Performance at scale is a competitive weapon (page speed = conversion)
- ▪You need integrations no app provides
- ▪You expect to sell the business — you own the asset
Head-to-Head
| Factor | Shopify | Custom |
|---|---|---|
| Time to launch | 2–8 weeks | 3–9 months |
| Upfront cost | $0–$5,000 | $25,000–$80,000 |
| Monthly cost | $300–$1,500 | $500–$2,500 |
| Transaction fees | 2.4%–2.9% + $0.30 | Negotiated processor rates |
| Customization | App-limited | Unlimited |
| Performance | Good, platform-constrained | Fully optimized |
| Owner's technical burden | Low | High (or ongoing engineering) |
| Risk | Platform rule changes, app churn | Scope creep, slower launch |
The "Headless" Middle Ground
Between Shopify and full custom sits headless commerce: Shopify as the backend (product, checkout, orders) with a fully custom frontend built in React/Next.js.
Why brands pick it:
- ▪Custom UX and speed on the frontend
- ▪Shopify handles the hard commerce plumbing
- ▪More flexibility than theme-based Shopify, less risk than full custom
The cost: $20,000–$50,000+ — because you're now running custom frontend code with two systems to maintain. Headless only makes sense if the conversion/UX benefit outweighs the engineering cost. For most small businesses, it doesn't.
How to Decide (Decision Framework)
Answer these honestly:
- ▪"What's the fastest I need to be selling?" → Under 3 months = Shopify. If the business model needs custom logic, budget 3–9 months.
- ▪"Does my business model fit a standard store?" → Products, cart, checkout = Shopify. Subscriptions, multi-vendor, custom pricing = custom.
- ▪"What's my projected volume in 24 months?" → Under $100k/mo, platform fees are acceptable. Above that, run the math on fees vs build cost.
- ▪"Do I have engineering resources?" → Custom needs ongoing development. Without it, you've bought infrastructure you can't operate.
- ▪"Is unique UX part of my competitive advantage?" → If your competitors all look identical, custom or headless can be the differentiator. If price/content wins, Shopify is fine.
The honest rule: most businesses overestimate their need for custom and underestimate the cost of operating it. Shopify handles 95% of e-commerce businesses well. Custom is for the 5% with a model Shopify can't serve — or the brands scaling past what the platform allows.
Migration Gotchas (The Hidden Trap)
The most expensive part of this decision is getting it wrong later:
- ▪Shopify → custom migration: rebuilding design, content, SEO URLs, and integrations — typically $15,000–$40,000
- ▪Custom → Shopify: a rewrite in the other direction, plus leaving behind custom code you paid for
- ▪Either way, you lose SEO equity if URLs and structure change without proper redirects
A store on a broken platform decision can cost you a full rebuild plus lost rankings plus weeks of downtime. This is why the decision deserves real analysis before you commit, not just "Shopify is cheap" or "custom is better."
The Bottom Line
- ▪Shopify: $300–$1,500/mo, launch in weeks, right for 95% of stores
- ▪Custom: $25,000–$80,000+, right for unique models and scale
- ▪Watch the monthly fees, not the sticker price — processing + apps are the real cost
- ▪Headless is the middle ground, but only worth it when UX is a weapon
- ▪The expensive mistake is the wrong decision, not the build — choose by business model and volume, not by opinion
If you're under $50k/mo with standard needs, start on Shopify and don't look back. If your model doesn't fit a template, custom is an investment in the business you're building — budget for the engineering to run it.
