# Custom Online Stores in Barcelona | Stack Studio

We design and build your online store on Shopify or from scratch: catalogue, payments and shipping set up, fast on mobile and easy to run.

We build your online store on Shopify or as a custom development, depending on your catalogue and how you sell. You run it: products, orders and shipping.

## What's included

- Shopify or a custom store, depending on what you sell
- Your own design and carefully written product pages
- Payments and shipping set up
- Fast on mobile, where most people buy
- Technical SEO for product and category pages
- Training to manage orders and products

## Your products in AI answers too

AI assistants already recommend products and stores. We prepare the store so they understand it. This is known as GEO (Generative Engine Optimization).

- Structured product data: price, availability and brand
- llms.txt and Markdown versions for agents
- Product pages that answer questions before people buy

## Frequently asked questions

**How much does an online store cost?**

It depends on the catalogue, the platform and the integrations. After a first conversation we send you a written quote.

**Shopify or custom?**

Shopify suits most catalogues and is easy to run. Custom makes sense if you need pricing, stock or integrations that Shopify does not handle well.

**Can my products show up in ChatGPT or Perplexity?**

It cannot be guaranteed, but the store can be ready for it: structured product data, llms.txt and clear product pages that AI assistants can read and cite.

**Can you migrate my current store?**

Yes. We migrate products and content when the source platform allows it, and we review the URLs so you keep your rankings.

**Who runs the store afterwards?**

You do. We hand over the store ready to go and show you how to run it. If you prefer, we carry on with monthly maintenance.
