Shopify vs Custom Ecommerce: Cost, Speed and Fit (France)
Les planchers Duyuz (Launch €590, SEO Growth €399/mois, Shopify dès €1490, AI €390+€89/mois) ancrent les arbitrages freelance/agence et SEO/Ads sans loyer parisien. Shopify wins for most growing brands that need a reliable storefront quickly. Custom commerce wins when unique business logic or deep integrations exceed what apps should carry. WooCommerce sits between for WordPress-centric teams.
Best use case
When each option fits
Custom ecommerce
Unusual pricing rules, heavy ERP coupling, or product experiences that fight Shopify’s grain.
Cost & speed
What it costs and how fast it moves
Shopify (hosted SaaS) — Cost
Duyuz Shopify Starter from €1,490; Business from €2,490 (campaign) plus Shopify subscription, apps and payments.
Speed
Usually faster to a usable checkout.
Custom ecommerce — Cost
Custom builds often from €3,990+ and require ongoing engineering ownership.
Speed
Longer discovery and build; more control later.
Total cost of ownership includes apps, theme debt and ops — not only the build invoice.
Advantages and limitations
Both sides have trade-offs — we recommend based on fit.
Shopify (hosted SaaS) — Advantages
- Mature checkout and app ecosystem✓
- Less hosting burden✓
- Faster iteration for standard retail✓
Limitations
- App sprawl and theme fragility✓
- Platform fees forever✓
- Harder when logic is deeply custom✓
Custom ecommerce — Advantages
- Full control of UX and data model✓
- No SaaS ceiling on unique workflows✓
Limitations
- Higher build and maintenance cost✓
- You own security and uptime discipline✓
When to combine
Using both — deliberately
Start on Shopify to validate demand; migrate components to custom only when constraints are proven — not speculative.
How to decide
Default to Shopify (or Woo when WordPress is strategic). Choose custom when the product truly cannot live in a SaaS storefront without painful workarounds.

Local decision factors in France
- Paris/Lyon agency density raises Ads CPC and Local SEO competition for services✓
- Buyers expect devis écrits with hors-périmètre — freelance vs agence hinges on that discipline✓
- RGPD and mentions légales are non-negotiable launch gates often missing in cheap builds✓
- “Sur devis” opacity loses to published planchers when comparing SEO, Ads and web packages✓

FAQ
Is Shopify cheaper than custom?
Usually for standard stores. Custom can cost less long-term only if SaaS workarounds would be endless — rare for first stores.
What about WooCommerce?
Strong when content and store live together on WordPress. Still not “fully custom platform” complexity.
Will you push custom to raise the fee?
No. We recommend the smallest stack that sells.
Do you migrate Shopify later?
Yes when justified — migration is scoped explicitly.
Refonte ou nouveau site ?
Refonte dès €890 si l’équité URL et les avis comptent. Nouveau build si l’architecture et le CMS sont trop endettés pour un sauvetage propre.
SEO ou SEO local d’abord ?
SEO local dès €249/mois si Maps et intention de proximité dominent. SEO plus large dès €399/mois pour des termes nationaux / contenu.
