## What E-commerce & Retail Software Looks Like for Your Business

- **Sector Expertise**: We build custom and headless storefronts, sync inventory and orders across your shop, POS and marketplaces (Amazon, marketplaces, retail), integrate payments and shipping, and add AI where it pays off: product discovery, abandoned-cart recovery, smart support and review auto-replies. The result is a store that loads fast, converts more and runs your operations, not just your catalogue.
- **Fast, Custom Storefronts**: Custom or headless commerce (Next.js + your platform) tuned for Core Web Vitals, because every second of load time is conversion you keep instead of losing.
- **Inventory, POS & Channel Sync**: One source of truth across your web shop, physical POS and marketplaces: no overselling, no manual stock juggling, orders unified in one place.
- **Conversion-Lifting AI**: Product discovery and recommendations, abandoned-cart recovery, a support assistant that answers product questions, and review auto-replies. AI aimed at revenue, not gimmicks.
- **Payments & Operations**: Stripe and local payment methods, shipping and returns flows, and back-office tooling that turns your store into an operations hub, not just a catalogue.
- **Bilingual Team (ES/EN)**: Our bilingual (Spanish/English) team ships, documents and supports your product in both languages, ideal for companies selling across Spain, LATAM and international markets.

## E-commerce & Retail Software: FAQ

### Shopify/WooCommerce or fully custom?

It depends on your needs. We build headless on top of platforms like Shopify when that's the fastest path, and fully custom when you need flows or integrations off-the-shelf platforms can't do. We recommend honestly based on your catalogue and operations.

### Can you sync with our marketplaces and POS?

Yes. We integrate your web shop, physical POS and marketplaces into one inventory and order source of truth, with webhooks and reconciliation so stock and orders stay consistent.

### How does AI actually increase sales?

Through better product discovery and recommendations, recovering abandoned carts with timely natural nudges, answering product questions instantly so buyers don't bounce, and auto-replying to reviews. Each is measured against revenue, not vanity metrics.

### Will my store be fast and SEO-friendly?

Yes. As developers we treat Core Web Vitals, structured data and crawlability as first-class. Fast, well-structured stores rank better and convert more, which is the whole point.

### Do you work with businesses across Spain and internationally remotely?

Yes. We work with clients across Spain and internationally, fully remote, with regular video check-ins and shared project boards. Most of our delivery is async and timezone-friendly, and we can meet on-site for kick-offs when it adds value.
