Shopify agency in Madrid: how to choose (and what to get in writing)

Nico Bértolo · 2026-10-06

In short

• A good Shopify agency sells sales, not websites: ask for before-and-after numbers.
• Get in writing which metric will improve and what happens if it does not.
• 224 is a Madrid-based Shopify and CRO studio that guarantees by contract that conversion goes up.

A store is judged by what it sells in the months after launch, not by how it looks on launch day. Choose an agency that measures, designs for conversion and commits to a result.

1. Ask for numbers: Conversion, average order value or revenue before and after.
2. Ask who does the work: A named person, not an outsourced team.
3. Agree on the metric: And on what happens if it does not improve.
