Shopify is excellent for starting. But beyond €50k/month in revenue, commissions and limitations become costly. A custom e-commerce can divide your costs by 3 in the long term.

How long to launch a store?

4 to 8 weeks for a complete store depending on the catalog. We can also migrate your existing store without service interruption.

How do you handle SEO?

Optimized architecture from design: clean URLs, schema markup, loading speed, automatic sitemap. Your store is ready for Google from launch.

Can I manage the catalog myself?

Absolutely. We develop an intuitive back-office adapted to your workflow. Video training included.

What about international payment?

Native multi-currency, automatic conversion, VAT management by country. Sell everywhere without friction.

Why a custom e-commerce?

Turnkey solutions (Shopify, WooCommerce) are fine for starting. But when you scale, their limitations become brakes: exploding commissions, impossible customization, shaky integrations. A custom e-commerce gives you back control.

Eliminate platform commissions that eat into your margins
Purchase journey optimized for YOUR audience (not a generic template)
Native integrations with your ERP, CRM, logistics
Multi-currency and multi-language for international
