E-commerce Website Development | Online Store

20 years of e-commerce expertise

Vitalyn has been helping businesses build and grow their online stores for more than 20 years. We've delivered dozens of e-commerce projects across a wide range of industries: fashion, food, B2B, publishing, cosmetics, equipment.

Our approach goes well beyond a simple product catalog: we design checkout flows optimized for conversion, smooth mobile interfaces and technically solid sites so your store gets found on Google.

Every project starts with an analysis of your business model so we can choose the e-commerce solution that fits best, not the one that's trendiest.

Frequently asked questions

How much should I budget for an online store?

Our e-commerce projects start at €6,000 for a standard Prestashop, Shopify or WooCommerce store. Custom projects start around €10,000. The final price depends on the number of products, the integrations required and the level of customization.

Which e-commerce platform should I choose?

Shopify is ideal for launching fast with few technical constraints. WooCommerce suits WordPress projects that need customization. Prestashop is recommended for tailored projects and custom features, open-source, with a controlled and predictable total cost of ownership. We make the choice during scoping, based on your budget, your catalog and your operational constraints.

Will my e-commerce site rank well on Google?

Yes. We optimize every e-commerce page for SEO: URL structure, title and meta tags, product structured data (Schema.org), load times and internal navigation. Product pages and category pages are designed for organic search.
