// Before platform, diagnosis

The biggest e-commerce mistake is choosing the platform before the diagnosis.

Many Paris SMBs launch a Shopify because everyone talks about it, then realize 18 months later that their catalog doesn't fit the model, transaction fees eat their margin, and required apps cost an extra €300/month. Conversely, some go custom because it sounds more prestigious, when Shopify would have covered 80 % of their needs.

My first deliverable is always a diagnosis. I look at your catalog, margin, volume, logistics processes and business constraints, then recommend the right platform. If Shopify is enough, I'll say so. If you need custom, we'll build it. If you already have a platform and just need consolidation, I'll handle it without selling unnecessary redesign.

For reference: Stripe fees in France are 1.5 % + €0.25 per EU card transaction, and GDPR compliance requires a privacy policy compliant with the CNIL. In 2025, the CNIL issued €487M in fines, a significant share for cookie mismanagement on e-commerce sites.

// Frequently asked

Everything you want to know about e-commerce in Paris

Shopify, WooCommerce or custom: which e-commerce platform for my Paris SMB?

+
Shopify is fastest to launch, most reliable and most expensive in margins (2 % transaction fees + €36/month subscription). Right for DTC brands launching with a standard catalog. WooCommerce is more flexible and cheaper but requires a technical team for maintenance and security. Custom Next.js + Stripe is the right choice when your business exceeds standard cases (multi-tier subscriptions, product configurators, complex business integration) or when your catalog exceeds several thousand SKUs. Free diagnosis before any choice.

How much does an e-commerce site in Paris cost?

+
Turnkey Shopify setup (custom theme, 50-200 products, payment and logistics integration): €2,990 to €5,990. Custom WooCommerce setup: €4,000 to €9,000. Custom Next.js + Stripe e-commerce with customer area: from €9,000. Add recurring fees: Shopify (€36/month), Stripe (1.4 % + €0.25 per EU transaction), Vercel hosting (free up to 100 GB bandwidth).

How long to deliver an e-commerce site?

+
Simple Shopify setup: 3-4 weeks after brief validation. Custom WooCommerce: 5-8 weeks. Custom Next.js e-commerce: 8-14 weeks. Timing depends mostly on your catalog readiness (photos, product sheets, technical specs) and number of business integrations (ERP, accounting, logistics).

How do you integrate payment and GDPR compliance for an e-commerce?

+
Stripe by default for payments (Ireland, GDPR-native, multi-currency, anti-fraud) or PayPal optional. For GDPR compliance: privacy policy compliant with LCEN, cookie banner, processing register, contract legal basis for order data, Brevo / Klaviyo integration for marketing emails with explicit consent. For sites subject to EU VAT OSS, I handle multi-country VAT configuration.

Which logistics integrations are possible?

+
For Shopify: Sendcloud, Boxtal, ColisPrivé, Mondial Relay, Chronopost natively. For WooCommerce and Next.js: direct API integrations with carriers, automatic label generation, real-time package tracking, dynamic shipping cost calculation. I can also plug in a WMS (Onestock, Shippingbo) for brands with their own warehouse.

What happens after go-live?

+
15-day warranty on delivered code. Evolution maintenance on monthly retainer (€99 to €499/month depending on volume) covering: monitoring, security updates, product/page additions, small evolutions, performance tracking. For structural evolutions (new feature, redesign), ad-hoc quote. You always keep full ownership of code and accounts.

Can you take over an existing e-commerce site that's underperforming?

+
Yes, frequent case: Shopify sites plateauing in SEO or performance, plugin-bloated WooCommerce crashing on traffic peaks, custom e-commerce abandoned by the original agency. Full audit (technical, SEO, conversion, code) within 5 days for €990, delivered with a prioritized action plan. I can then take over the project or refer you to the right provider if I'm not the right option.
