Custom online store: a unique e-commerce, built to sell

When your e-commerce needs more than a template

E-commerce templates are fine to start, but they have a ceiling: they limit your design, the buying experience and integrations, and slow down as you grow. When you sell for real, you need a store built to your measure.

At FCweb we design and build custom online stores, around your catalogue, your operations and your customer. Optimised checkout, secure gateways, integration with your ERP or logistics, and a buying experience designed to convert. No artificial limits.

15+ years and an in-house team in Barcelona, with projects for leading brands. Direct contact with the people who design and build your store.
