What we set out to do
The store had to be quick to use and, at the same time, ready to connect to whatever sales system the business chooses, without rebuilding the shopping experience.
Tienda Premium is a studio demo, designed, developed, and deployed by DARVIA: it is not a client commission and does not prove commercial results.
What we built
An online store with a catalog, cart, and checkout process. The demo walks through the full interface; payments run in test mode, and the real-time and assistant features are interface only.

Key technical decision
The checkout was decoupled behind a single gateway interface: the provider can be swapped by configuration without touching the purchase flow or global state.
What you can check and what is outside the scope
You can check
The catalogue, cart and checkout screens.
Project limits
Payments run in test mode. Real-time features and the assistant are interface only; they do not establish live charges, automated support or real orders.
What it demonstrates
You can switch payment methods later without rebuilding the store, because the checkout does not depend on any single provider.
