Most Shopify agencies only build for clients. We also ship our own products.

Two today, more in the works. Everything we learn building for the Theme Store and the App Store goes into client work.

Questions brands ask us

What does Developpy do?

Developpy is a Shopify software house founded by two Shopify Experts. We design, build and migrate Shopify stores for brands, and we make our own Shopify products: the Universe theme and the Checkout Upsell Builder app.

How much does a Shopify project cost?

Every project gets its own quote after a short call, once we know the scope. We don't publish prices or packages.

How long does a new store take?

It depends on the catalog, the design and the integrations. You get a launch date in the written scope before work starts, after a 15-minute call.

Do you work outside Spain and Italy?

Yes. We work with brands worldwide, in English, Spanish and Italian, from Barcelona and Padova.

Can you customize the Universe theme for our brand?

Yes. We customize Universe for brands, as a project or on a retainer.
