Minha Loojinha

WhatsApp storefront SaaS for fashion sellers

Minha Loojinha

Context

Hundreds of Brazilian fashion sellers sell through Instagram and WhatsApp — without an organized catalog, without a clear flow, without polish. Minha Loojinha fixes that: the brand registers products, sets up the storefront, and the end customer browses a shareable link that ends up in WhatsApp with the order pre-filled.

Positioning

For the buyer: a modern e-commerce experience (photo, size, price, shipping) with checkout in WhatsApp — no card friction, no signup.

For the seller: a professional storefront integrated with Instagram, an embedded admin panel, product and inventory management — without hiring an agency or a developer.

Architecture

  • Multi-tenant SaaS in Next.js (App Router) — each store has its own domain/subdomain, admin and isolated catalog.
  • Pre-filled WhatsApp order — the system generates the full message (product, size, price, shipping) for the customer to send in one tap.
  • Embedded admin — no separate app, same deploy, same session.
  • Public storefront using SSG/ISR for performance and SEO.
  • Single plan — R$ 16.90/mo, no per-sale fee. Affordable-by-design positioning.

Status

Live in production with real merchants. Continuous validation with the target audience in parallel to the technical build.
