Shopify agency in Paris

Custom Shopify stores, theme refits and migrations

A Shopify store is quick to launch and hard to make your own. Most of the work is in what a theme does not give you: product pages that carry the brand, a cart and checkout that hold up to payment, and a catalogue your team can run without a developer.

Della Mattia is an independent design and code studio founded in Paris in 2017. We build Shopify stores for fashion, hospitality and cultural brands in France, the United Kingdom and Spain, and the Webflow brand sites that sit next to them.

What we do on Shopify

Theme refit, from 5,500 EURAn existing theme adapted to the brand: typography, product pages, collections, cart. The faster and cheaper route.
Custom theme, from 12,000 EURBuilt from scratch for brands whose product pages need to look like no one else’s. Editorial pages your team edits itself.
Cart and checkoutThe moment of the visit with the highest intent. We redesign the cart and work within Shopify’s checkout so the brand holds up to payment.
Migration to ShopifyFrom WooCommerce, Squarespace or PrestaShop, with redirects and metadata handled. See our migration guide.
Multilingual storesEnglish, French, Spanish, Italian. One store, several markets, with the right titles and structured data in each language.
SEO and GEOSo that Google and AI assistants describe the brand, its products and its prices correctly.
Ongoing maintenanceNew collections, capsule landing pages and improvements after launch, as on L’Île Bleue.
